Most patients will not make a full recovery from attention-deficit/hyperactivity disorder in adulthood. This late-breaking finding headlined the World Congress on ADHD – Virtual Event. Held under the specter of SARS-CoV-2, the virtual program delved into the latest research on ADHD pathophysiology, imaging, genetics, and issues on medical and psychiatric comorbidities.

However, one of the conference’s highlights was a piece of unpublished work on remission patterns by Margaret Sibley, PhD, associate professor of psychiatry and behavioral sciences at the University of Washington, Seattle.

Anywhere from 65% to 67% of young adults have desistant ADHD – meaning that they no longer meet criteria. Only up to 23% experience full remission, said Dr. Sibley during a special late-breaking session. All research on remission and most on persistence consider just one endpoint – nothing is known about longitudinal fluctuations in remission status over time.

Her research sought to answer a key question: Do people fully recover from ADHD?

Using data from the Multimodal Treatment of Attention Deficit Hyperactivity Disorder (MTA) Study, Dr. Sibley prospectively followed over 550 children aged 7-9.9 years with DSM-IV combined-type ADHD over 14 years, until 16 years after baseline, using interviews, questionnaires, and rating scales to track symptoms, impairment, and treatment history.

The researchers also came up with a “winning” definition for full remission, which included three or fewer symptoms of inattention and hyperactive impulsivity from all available reporters, negligible ADHD-related impairment based on preestablished impairment rating thresholds, and discontinuation of medication and behavioral treatments for at least a month prior to assessment.

In the longitudinal results, Dr. Sibley and colleagues reported that the majority (63.8%) demonstrated fluctuations between full or partial remission and ADHD recurrence. Only 9.1% sustained full remission over the course of the study. From these findings, ADHD appears to be a fluctuating disorder. While it continues into adulthood for most people, there may also be periods of remission or “good functioning.”

Most desistance from ADHD represents partial, not full remission, said Dr. Sibley. The results also show that recovery by young adulthood is very rare – most patients with remitted ADHD have recurrences.

These are important findings, said Luis Augusto Rohde, MD, PhD, who co-organized the congress’ scientific program committee with Manfred Gerlach, PhD. It shows that a patient’s ADHD may sometimes be more definitive and at other times, no clear phenotype expression emerges.

COVID’s influence

COVID-19 greatly influenced this year’s program’s agenda, said Dr. Rohde. “There’s a lot of evidence that ADHD patients are at greater risk for COVID-19, which is not a surprise,” said Dr. Rohde, professor of child and adolescent psychiatry at the Federal University of Rio Grande do Sul’s department of psychiatry in Porto Alegre, Brazil.

ADHD is a combination of genetic liability and the demands of the environment. “In times like we are living in right now, if you have increasing demands and stress from the environment, you trigger symptoms in those even with lower genetic liability,” he said. ADHD’s pathophysiology involves attention and executive deficit disorder, which means these patients may not follow strategies to avoid infection.

This shows why COVID was so important to the discussion of program topics, he said.

Two experts addressed this subject head on in a point-counterpoint debate, “Residual effects of the 2019 pandemic will mirror the 1918 pandemic: Will we have lots of new ADHD cases?” James Swanson, PhD, professor of pediatrics at the University of California, Irvine, projected that biological coeffects of COVID-19 will lead to ADHD symptoms, generating potentially 5 million new ADHD cases.

David Coghill, MBChB, MD, a professor of child adolescent mental health at the University of Melbourne, countered that not enough data are available yet to back this hypothesis. “Researchers are asking this question, but clinically we don’t know enough.”

While the COVID virus might not directly lead to more cases of ADHD, this could potentially happen indirectly through environmental agents of the pandemic, offered Dr. Rohde. “We’ve clearly seen in our appointments with families and children that they can’t face the amount of schooling and working from home,” he said.

 

Novel treatments

The conference also addressed new treatments and nonpharmacologic interventions in the pipeline for ADHD. “We had a chance to discuss the possibilities about new medications that address the problems in the current market and to show the potential usefulness of nonpharma interventions such as neuromodulations in ADHD,” said Dr. Rohde. Speakers discussed strategies ranging from family-based mindfulness interventions to oligoantigenic diets in children with ADHD.

Other researchers are looking at novel digital tools to help patients manage and treat ADHD. Adherence is a major problem in chronic disorders like hypertension, diabetes, epilepsy, and ADHD, said Dr. Rohde. “Due to ADHD symptomatology including inattention, novelty-seeking, executive deficits, and difficulties in persistence, it is an even bigger problem in this disorder.”

Speakers at the “ADHD in the digital age – From pitfalls to challenges” session discussed video game strategies to reduce ADHD impairment, and a texting app to improve adherence. Dr. Rohde talked about the FOCUS app, which fosters collaboration between patients, families, and caregivers to efficiently track ADHD symptoms and help customize treatments.

Studies suggest these tools can significantly improve adherence. They’re also well accepted by patients, said Dr. Rohde. While the expectations are high, digital interventions are not a substitute for medication. “More data is needed to include them as part of the clinical interventions for ADHD.”

Dr. Sibley received book royalties from Guilford Press. Dr. Rohde has received grant or research support from, served as a consultant to, and served on the speakers’ bureau of Bial, Medice, Novartis/Sandoz, Pfizer, and Shire/Takeda in the last 3 years. The ADHD and Juvenile Bipolar Disorder Outpatient Programs chaired by Dr. Rohde have received unrestricted educational and research support from the following pharmaceutical companies in the last 3 years: Novartis/Sandoz and Shire/Takeda. Dr. Rohde has received authorship royalties from Oxford Press and ArtMed and travel grants from Shire to take part in the 2018 APA annual meeting. Dr. Swanson has two patents: (PIXA4), which uses a “time-of-flight” camera to measure growth of infants, and a provisional patent on the mechanism of tolerance to stimulant medication (PATSMTA). He has received travel support from Medice and has done legal review for NLS. Dr. Coghill worked for several pharmaceutical companies but had no disclosures relevant to the session debate on the pandemic.

Attention-deficit/hyperactivity disorder and autism spectrum disorder (ASD) often coexist in children and adults, but the range of cognitive abilities can vary widely in these patients. Researchers from around the world are leveraging symptom, cognitive assessment, and neurobiological measures to gain insights on how individuals with ADHD/ASD approach and solve problems.

Several experts discussed the progress of their research during the session, “Overlap and differences of ADHD and autism – new findings of functional imaging and cognition studies” at the World Congress on ADHD – Virtual Event.

“The overlap of these two disorders is a critical issue for our field,” said Sarah Karalunas, PhD, assistant professor of clinical psychology at Purdue University, West Lafayette, Ind., who moderated the session. Clinicians are often asked to make differential diagnoses between these two disorders. Only recently has the DSM-5 allowed their codiagnosis. “There’s increasing recognition that there may be shared cognitive and physiological features that reflect their shared risk and account for the high levels of symptom overlap,” said Dr. Karalunas.
 

Shared cognitive markers

Under the DSM’s change, “it’s now recognized that an estimated 20%-60% of children with ASD have comorbidities with ADHD, and around 20%-40% of children with ADHD have ASD symptoms,” said Beth Johnson, PhD, a research fellow with the Turner Institute for Brain and Mental Health at Monash University, Melbourne.

The shared overlap on genetic traits and comorbidities such as intellectual disability, anxiety, depression, and oppositional defiant disorder, make it difficult for clinicians to predict clinical outcomes, noted Dr. Johnson.

“We’re now understanding that they’re likely to be multiple autisms and ADHDs, that these symptoms exist on a spectrum of severity or ability,” she said. Dr. Johnson discussed a data-driven subtyping approach based on neurocognitive and symptom profiles in children with ADHD. The aim was to better understand how symptoms are managed across ADHD, ASD and comorbid ASD-ADHD.

As part of this research, her team recruited 295 controls and 117 children with ADHD who underwent clinical phenotyping and also completed working memory tasks, stop signal, and sustained attention tasks.

The researchers divided the children into four stable clusters based on the ADHD rating scale and autism questionnaire data: high ASD/ADHD traits, high ADHD/low ASD, low ADHD/moderate ASD, and low ADHD/ASD. Approximately half of the children with ADHD showed moderate to high ASD symptoms. Looking at neurocognition across the tasks, unsurprisingly, performance was lowest among the high-ASD/ADHD children, with performance on the stop signal being the most pronounced. “Notably, performance on the working memory task worsened with increasing ADHD symptoms,” she reported.
 

Drift model identifies information processing

Dr. Karalunas has also compared subgroups of ADHD and ASD children. “Our analysis examined whether cognitive impairments in ASD reflect a shared risk mechanism or co-occurring ADHD symptoms and why we see an overlap in these types of impairments,” she said.

Her study included 509 children with ADHD, 97 with ASD, and 301 controls (typical development). All three groups underwent a full cognitive assessment battery that measured attention arousal, basic processing speed, and working memory. Those tasks were collapsed into a series of variables as well as a set of tasks measuring response inhibition, switching, interference control, reward discounting, and measure of reaction time variability.

Four cognitive profiles emerged: a typically developing group, an ADHD group, an ASD group with low levels of ADHD symptoms and an ASD group with high levels of ADHD symptoms.

The ADHD group did worse on many of the tasks than the control group, and the ASD group with low ADHD levels also did poorly relative to the typically developing sample. This shows that autism – even in absence of co-occurring ADHD – demonstrates more cognitive impairment than typically developing kids. The ADHD group with high levels of autism did the most poorly across all of the tasks.

The findings also revealed a symptom severity pattern: the group with fewer symptoms did the best and the group with the most symptoms did the worst. “Overall, this reflects severity of impairment,” said Dr. Karalunas.

To identify measures more specific to either ADHD or autism, Dr. Karalunas and colleagues did a follow-up analysis to characterize cognitive performance. To accomplish this, they applied a drift-diffusion model to the same four cognitive profiles. The model assessed three parameters: drift rate, which relates to the speed or efficiency of information processing, boundary separation or speed accuracy trade-offs (impulsivity), and nondecision time such as motor preparation.

Using the same four cognitive profiles, they found that the ADHD group had slower drift rate relative to the control, although the two groups did not differ on boundary separation, which meant there were no differences on waiting to need to respond. The ADHD group had faster nondecision times. “This is a classic pattern, shown in the literature,” said Dr. Karalunas.
 

In other results, an interesting pattern began to evolve

Both ASD groups, for example, had much wider boundary separations, which meant they were waiting to be sure before they responded than the ADHD or typically developing groups. In contrast, the two ADHD groups had much faster non-decision times, whereas the two non-ADHD groups had similar nondecisions times.

Unlike the previous analysis, which saw a symptom severity pattern develop, “we’re getting two parameters that seem to track much more specifically to specific symptom domains,” observed Dr. Karalunas.

The results suggest there’s a substantial overlap in cognitive impairments in ADHD/ASD. “But we have pretty strong evidence at this point that these similarities are not accounted for by symptom overlap, especially for things like response and inhibition, working memory and processing speed. These seem to be independently related to ADHD and autism, regardless of the level of comorbid ADHD symptoms in the autism group,” said Dr. Karalunas.

The hope is to expand on these types of analyses to address the interaction of cognition-emotion and social cognition, and empirically define groups based on cognitive performance, she said.
 

Neurocognitive studies

Researchers have also been studying neural networks to assess ASD and ADHD. Roselyne Chauvin, PhD, a postdoctoral associate at Washington University, St. Louis, discussed the concept of “a task generic connectome,” in which researchers look for a common network between targeted task paradigms to get closer to a common alteration across impairments.

In her research, Dr. Chauvin and colleagues looked at connectivity modulations across three tasks: working memory, reward processing tasks, and stop signal tasks, comparing ADHD patients to siblings and controls. The ADHD group showed reduced sensitivity or a smaller number of connections modulated in the tasks compared with the other groups. Researchers wondered where those missed connections were located.

Dividing the cohorts into task generic and task specific groups, Dr. Chauvin and colleagues found that the ADHD group lacked common processing skills. They were also able to identify reproducible missing circuits in the ADHD participants. Among the cohorts, there was a higher modulation of task-specific edges in the ADHD group.

The ADHD patients seemed to be using more task-tailored alternative strategies that were more challenging and suboptimal.

She also previewed her ongoing work with the EU-AIMS Longitudinal European Autism Project (LEAP) database to study ASD-ADHD comorbidity. In this project, she and her colleagues looked at several tasks: probing emotion processing, inhibitory control, theory of mind, and reward anticipation. Comparing ASD groups with or without ADHD comorbidity or a shared connection, she and her team were able to devise a functional profile predictive of ADHD severity. As an example, “for the connection only used by the ASD with ADHD comorbidity, the more they were using those connections of higher amplitude in the modulation, inside this subset of connection, the higher they would have ADHD severity,” said Dr. Chauvin.

Neural correlates of different behavioral and cognitive profiles haven’t been widely studied, according to Charlotte Tye, PhD, who’s based at the Institute of Psychiatry, Psychology & Neuroscience, King’s College, London. Electroencephalography is a useful technique for understanding the neural correlates of cognitive impairments and teasing apart different models of co-occurrence in ASD and ADHD. 

Dr. Tye and colleagues tested this approach in a cohort of boys aged 8-13 years diagnosed with ASD and/or ADHD, measuring EEG while the children did various continuous performance tasks to assess changes in brain activity. Examining P3 amplitude (event-related potential components) they found that children with ADHD or ADHD+ASD showed an attenuated amplitude of the P3, compared with typically developing children and those with ASD.

“This suggests children with an ADHD diagnosis exhibited reduced inhibitory control,” said Dr. Tye. In contrast, children with ASD showed reduced conflict monitoring as indexed by altered N2 amplitude across task conditions.

These, and other studies conducted by Dr. Tye and colleagues indicate that children with ADHD show reduced neural responses during attentional processing, whereas autistic children show typical neural responses, supporting specific profiles.

“Autistic children with a diagnosis of ADHD appear to show the unique patterns of neural responses of autism and ADHD, supporting an additive co-occurrence rather than a distinct condition. This contributes to identification of transdiagnostic subgroups within neurodevelopmental conditions for targeting of personalized intervention, and suggests that children with co-occurring autism and ADHD require support for both conditions,” said Dr. Tye.

An important takeaway from all of these findings is “we can’t look just at how someone does overall on a single test,” said Dr. Karalunas in an interview. “There is a tremendous amount of variability between people who have the same diagnosis, and our research really needs to account for this.”

Attention-deficit/hyperactivity disorder and autism spectrum disorder (ASD) often coexist in children and adults, but the range of cognitive abilities can vary widely in these patients. Researchers from around the world are leveraging symptom, cognitive assessment, and neurobiological measures to gain insights on how individuals with ADHD/ASD approach and solve problems.

Comparing ASD groups with or without ADHD comorbidity or a shared connection, she and her team were able to devise a functional profile predictive of ADHD severity. As an example, “for the connection only used by the ASD with ADHD comorbidity, the more they were using those connections of higher amplitude in the modulation, inside this subset of connection, the higher they would have ADHD severity,” said Dr. Chauvin.

Neural correlates of different behavioral and cognitive profiles haven’t been widely studied, according to Charlotte Tye, PhD, who’s based at the Institute of Psychiatry, Psychology & Neuroscience, King’s College, London. Electroencephalography is a useful technique for understanding the neural correlates of cognitive impairments and teasing apart different models of co-occurrence in ASD and ADHD. 

Dr. Tye and colleagues tested this approach in a cohort of boys aged 8-13 years diagnosed with ASD and/or ADHD, measuring EEG while the children did various continuous performance tasks to assess changes in brain activity. Examining P3 amplitude (event-related potential components) they found that children with ADHD or ADHD+ASD showed an attenuated amplitude of the P3, compared with typically developing children and those with ASD.

“This suggests children with an ADHD diagnosis exhibited reduced inhibitory control,” said Dr. Tye. In contrast, children with ASD showed reduced conflict monitoring as indexed by altered N2 amplitude across task conditions.

These, and other studies conducted by Dr. Tye and colleagues indicate that children with ADHD show reduced neural responses during attentional processing, whereas autistic children show typical neural responses, supporting specific profiles.

“Autistic children with a diagnosis of ADHD appear to show the unique patterns of neural responses of autism and ADHD, supporting an additive co-occurrence rather than a distinct condition. This contributes to identification of transdiagnostic subgroups within neurodevelopmental conditions for targeting of personalized intervention, and suggests that children with co-occurring autism and ADHD require support for both conditions,” said Dr. Tye.

An important takeaway from all of these findings is “we can’t look just at how someone does overall on a single test,” said Dr. Karalunas in an interview. “There is a tremendous amount of variability between people who have the same diagnosis, and our research really needs to account for this.”

Attention-deficit/hyperactivity disorder and autism spectrum disorder (ASD) often coexist in children and adults, but the range of cognitive abilities can vary widely in these patients. Researchers from around the world are leveraging symptom, cognitive assessment, and neurobiological measures to gain insights on how individuals with ADHD/ASD approach and solve problems.

Several experts discussed the progress of their research during the session, “Overlap and differences of ADHD and autism – new findings of functional imaging and cognition studies” at the World Congress on ADHD – Virtual Event.

“The overlap of these two disorders is a critical issue for our field,” said Sarah Karalunas, PhD, assistant professor of clinical psychology at Purdue University, West Lafayette, Ind., who moderated the session. Clinicians are often asked to make differential diagnoses between these two disorders. Only recently has the DSM-5 allowed their codiagnosis. “There’s increasing recognition that there may be shared cognitive and physiological features that reflect their shared risk and account for the high levels of symptom overlap,” said Dr. Karalunas.
 

Shared cognitive markers

Under the DSM’s change, “it’s now recognized that an estimated 20%-60% of children with ASD have comorbidities with ADHD, and around 20%-40% of children with ADHD have ASD symptoms,” said Beth Johnson, PhD, a research fellow with the Turner Institute for Brain and Mental Health at Monash University, Melbourne.

The shared overlap on genetic traits and comorbidities such as intellectual disability, anxiety, depression, and oppositional defiant disorder, make it difficult for clinicians to predict clinical outcomes, noted Dr. Johnson.

“We’re now understanding that they’re likely to be multiple autisms and ADHDs, that these symptoms exist on a spectrum of severity or ability,” she said. Dr. Johnson discussed a data-driven subtyping approach based on neurocognitive and symptom profiles in children with ADHD. The aim was to better understand how symptoms are managed across ADHD, ASD and comorbid ASD-ADHD.

As part of this research, her team recruited 295 controls and 117 children with ADHD who underwent clinical phenotyping and also completed working memory tasks, stop signal, and sustained attention tasks.

The researchers divided the children into four stable clusters based on the ADHD rating scale and autism questionnaire data: high ASD/ADHD traits, high ADHD/low ASD, low ADHD/moderate ASD, and low ADHD/ASD. Approximately half of the children with ADHD showed moderate to high ASD symptoms. Looking at neurocognition across the tasks, unsurprisingly, performance was lowest among the high-ASD/ADHD children, with performance on the stop signal being the most pronounced. “Notably, performance on the working memory task worsened with increasing ADHD symptoms,” she reported.
 

Drift model identifies information processing

Dr. Karalunas has also compared subgroups of ADHD and ASD children. “Our analysis examined whether cognitive impairments in ASD reflect a shared risk mechanism or co-occurring ADHD symptoms and why we see an overlap in these types of impairments,” she said.

Her study included 509 children with ADHD, 97 with ASD, and 301 controls (typical development). All three groups underwent a full cognitive assessment battery that measured attention arousal, basic processing speed, and working memory. Those tasks were collapsed into a series of variables as well as a set of tasks measuring response inhibition, switching, interference control, reward discounting, and measure of reaction time variability.

Four cognitive profiles emerged: a typically developing group, an ADHD group, an ASD group with low levels of ADHD symptoms and an ASD group with high levels of ADHD symptoms.

The ADHD group did worse on many of the tasks than the control group, and the ASD group with low ADHD levels also did poorly relative to the typically developing sample. This shows that autism – even in absence of co-occurring ADHD – demonstrates more cognitive impairment than typically developing kids. The ADHD group with high levels of autism did the most poorly across all of the tasks.

The findings also revealed a symptom severity pattern: the group with fewer symptoms did the best and the group with the most symptoms did the worst. “Overall, this reflects severity of impairment,” said Dr. Karalunas.

To identify measures more specific to either ADHD or autism, Dr. Karalunas and colleagues did a follow-up analysis to characterize cognitive performance. To accomplish this, they applied a drift-diffusion model to the same four cognitive profiles. The model assessed three parameters: drift rate, which relates to the speed or efficiency of information processing, boundary separation or speed accuracy trade-offs (impulsivity), and nondecision time such as motor preparation.

Using the same four cognitive profiles, they found that the ADHD group had slower drift rate relative to the control, although the two groups did not differ on boundary separation, which meant there were no differences on waiting to need to respond. The ADHD group had faster nondecision times. “This is a classic pattern, shown in the literature,” said Dr. Karalunas.
 

In other results, an interesting pattern began to evolve

Both ASD groups, for example, had much wider boundary separations, which meant they were waiting to be sure before they responded than the ADHD or typically developing groups. In contrast, the two ADHD groups had much faster non-decision times, whereas the two non-ADHD groups had similar nondecisions times.

Unlike the previous analysis, which saw a symptom severity pattern develop, “we’re getting two parameters that seem to track much more specifically to specific symptom domains,” observed Dr. Karalunas.

The results suggest there’s a substantial overlap in cognitive impairments in ADHD/ASD. “But we have pretty strong evidence at this point that these similarities are not accounted for by symptom overlap, especially for things like response and inhibition, working memory and processing speed. These seem to be independently related to ADHD and autism, regardless of the level of comorbid ADHD symptoms in the autism group,” said Dr. Karalunas.

The hope is to expand on these types of analyses to address the interaction of cognition-emotion and social cognition, and empirically define groups based on cognitive performance, she said.
 

Neurocognitive studies

Researchers have also been studying neural networks to assess ASD and ADHD. Roselyne Chauvin, PhD, a postdoctoral associate at Washington University, St. Louis, discussed the concept of “a task generic connectome,” in which researchers look for a common network between targeted task paradigms to get closer to a common alteration across impairments.

In her research, Dr. Chauvin and colleagues looked at connectivity modulations across three tasks: working memory, reward processing tasks, and stop signal tasks, comparing ADHD patients to siblings and controls. The ADHD group showed reduced sensitivity or a smaller number of connections modulated in the tasks compared with the other groups. Researchers wondered where those missed connections were located.

Dividing the cohorts into task generic and task specific groups, Dr. Chauvin and colleagues found that the ADHD group lacked common processing skills. They were also able to identify reproducible missing circuits in the ADHD participants. Among the cohorts, there was a higher modulation of task-specific edges in the ADHD group.

The ADHD patients seemed to be using more task-tailored alternative strategies that were more challenging and suboptimal.

She also previewed her ongoing work with the EU-AIMS Longitudinal European Autism Project (LEAP) database to study ASD-ADHD comorbidity. In this project, she and her colleagues looked at several tasks: probing emotion processing, inhibitory control, theory of mind, and reward anticipation. Comparing ASD groups with or without ADHD comorbidity or a shared connection, she and her team were able to devise a functional profile predictive of ADHD severity. As an example, “for the connection only used by the ASD with ADHD comorbidity, the more they were using those connections of higher amplitude in the modulation, inside this subset of connection, the higher they would have ADHD severity,” said Dr. Chauvin.

While it’s possible that residual effects of SARS-CoV-2 could lead to an eruption of attention-deficit/hyperactivity disorder (ADHD) cases, a debate at the World Congress on ADHD – Virtual Event underscored the fact that this is still a hypothesis. The bottom line is there needs to be more data, said Luis Augusto Rohde, MD, PhD, cochair of the congress’ scientific program committee and moderator of the session, “Residual effects of the 2019 pandemic will mirror the 1918 pandemic: Will we have lots of new ADHD cases?”

Considering the current pattern of the pandemic, there is not enough evidence for this to be a concern, Dr. Rohde said in an interview.

James Swanson, PhD, professor of pediatrics at the University of California, Irvine, opined that biological co-effects of COVID-19 are likely to have selective effects in children that may produce symptoms representative of ADHD. Using the 1918 Spanish flu pandemic as a historical reference, he estimated that COVID-19 would produce 5 million individuals with new-onset symptoms related to ADHD. “If these cases meet DSM-5 or ICD-11 criteria, there will be lots of new ADHD cases,” he predicted.

David Coghill, MD, a professor of child adolescent mental health at the University of Melbourne, observed that the sums Dr. Swanson presented “are based on maxing out the potential rather than looking at the sums more realistically.”
 

Could the 1918 pandemic offer clues?

In a commentary, Dr. Swanson and Nora D. Volkow, MD, wrote about “lessons learned” from the 1918 pandemic, and how residual sequelae in that era led to a condition labeled hyperkinetic syndrome in children. “It may be worthwhile to consider the hypothesis that the COVID-19 pandemic may result in a novel etiologic subtype of ADHD that clinicians may recognize in patients in the future,” wrote the commentators. 

In survivors of the 1918 pandemic, brain inflammation or encephalitis sometimes emerged as residual sequelae, said Dr. Swanson. In some adult cases, these symptoms were diagnosed as “encephalitis lethargica” (EL) and were associated with Parkinson’s disease. In 1930, based on patients evaluated after 1918, researchers Franz Kramer and Hans Pollnow at Charité Hospital in Berlin described the behavioral manifestation of EL in children as hyperkinetic syndrome, a condition that was characterized by symptoms similar to the properties of ADHD: lack of concentration, insufficient goal orientation, and increased distractibility. “They even reported on autopsy cases that described brain regions that we now know are associated with ADHD from decades of brain imaging studies,” said Dr. Swanson.

COVID-19 rarely results in severe respiratory problems in children but the absolute number requiring hospitalization has accumulated and is now relatively large, said Dr. Swanson. One study of 1,695 severe COVID-19 cases in children and adolescents used MRI and detected neural effects in specific brain regions such as basal ganglia and frontal lobes that previous research had associated with ADHD. Approximately 22% of these rare but severe cases had documented neurologic involvement, and studies of affected children with mild or none of the initial respiratory symptoms of COVID-19 also detected similar selective effects in these brain regions.

A recent survey of medical records of 80 million people that identified 240,000 COVID cases (mostly adults) revealed that a third had neurological and psychiatric sequelae. Dr. Swanson also mentioned an article he wrote more than a decade ago on environmental as well as genetic factors that resulted in etiologic subtypes of ADHD, which provided a model for the impact of COVID-19 on specific brain regions that are associated with ADHD.

So far, the COVID-19 pandemic has produced 150 million cases worldwide and there are about 100 million survivors, setting an estimate of a maximum number of cases with residual sequelae. “I think that severe COVID-19 will probably be related to severe residual sequelae, and that mild or asymptomatic COVID-19 may be associated with less severe residual sequelae, which may resemble ADHD” said Dr. Swanson. If one-third of the cases manifest in some neurologic or psychiatric systems, this means 27 million would have residual sequelae. If 20% have impaired concentration or brain fog, this could result in about 5 million ADHD cases, he said. 
 

Estimates aren’t evidence

The Swanson/Volkow commentary contains a lot of references to “might, could, and may,” said Dr. Coghill. While it’s true that COVID-19 could produce a novel etiologic subtype of ADHD, “the point here is at the moment, all of this is based on hypotheses,” he said.

The Spanish flu did produce mental health consequences – survivors reported depression, sleep disturbances, mental distraction, dizziness, and difficulties coping at work. In the United States, flu death rates from 1918 to 1920 were directly attributed to suicide rates. Unfortunately, these impacts weren’t widely researched, said Dr. Coghill.

It also seems clear that the 1918 Spanish flu outbreak was associated with significant neurological consequences, said Dr. Coghill. By 1919 and 1920, physicians and researchers in the United Kingdom were reporting increases in a variety of symptoms among some patients recovering from flu, such as neuropathy, neurasthenia, meningitis, degenerative changes in nerve cells, and a decline in visual acuity.

The EL cases Dr. Swanson mentioned did coincide with and reach epidemic proportions alongside the Spanish flu. “But still, a causal relationship is far from proven,” said Dr. Coghill.

Sol Levy, MD, described a “disease of criminals” following the 1918 pandemic, in which patients exhibited a high degree of general hyperkinesis, a difficulty in maintaining quiet attitudes, abruptness and clumsiness, and “explosive motor release of all voluntarily inhibited activities.”

However, these impairments suggest a much broader presentation typically seen in ADHD, noted Dr. Coghill.

Neurological complications occur more commonly than initially thought in severe COVID-19, with estimates ranging from 36% to 84%. But in a systematic review of neuropsychiatric complications of severe coronavirus infection, researchers found few psychiatric sequelae of these infections. While they did mention impaired concentration and difficulties with emotional ability, it’s very important to remember that these conditions “are cardinal symptoms of a wide range of psychiatric disorders,” said Dr. Coghill.

Overall, more neurological and neuropsychiatric symptoms largely confine to those with severe COVID-19, meaning they’re much less likely to occur in children and young adults, he said.

If there are severe effects of COVID-19, Dr. Swanson countered that “they might have more ADHD than the complex residual effects [Dr. Coghill] described. I hope that he’s right, but I do think there will be biological co-effects of COVID-19 that will produce symptoms that are more ADHD than other neurological disorders.”
 

Epigenetic effects

Researchers are now seeing transgenerational and intergenerational effects of potential infection. “So I certainly back high-quality studies looking at the effects of maternal and paternal infection on offspring,” said Dr. Coghill. Establishing clinical cohort studies to follow up on this population would be essential in understanding the risks of SARS-CoV-2. “That might be one way we’ll see an increase in ADHD,” said Dr. Coghill.

The reality is COVID-19 hasn’t been around for that long, and current knowledge about it is limited, he said. Rapid publications, cross-sectional or retrospective data, and poor methodological quality and rigor make generalizability difficult. In addition, limited testing and detection probably underestimate prevalence of neurological and neuropsychiatric complications.

“If history teaches us anything, it is that we should always be measured in how we glean lessons from the past. So let’s not get ahead of ourselves,” he cautioned.

An informal, post-discussion survey of session participants revealed that a slight majority – 55%-60% – expected residual effects of COVID-19 to lead to more ADHD, compared to 40%-45% who didn’t think this would happen.

Dr. Swanson has two patents: (PIXA4), which uses a “time-of-flight” camera to measure growth on infants, and a provisional patent on the mechanism of tolerance to stimulant medication (PATSMTA). Dr. Coghill worked for several pharmaceutical companies but had no disclosures relevant to this debate.

“If history teaches us anything, it is that we should always be measured in how we glean lessons from the past. So let’s not get ahead of ourselves,” he cautioned.

An informal, post-discussion survey of session participants revealed that a slight majority – 55%-60% – expected residual effects of COVID-19 to lead to more ADHD, compared to 40%-45% who didn’t think this would happen.

Dr. Swanson has two patents: (PIXA4), which uses a “time-of-flight” camera to measure growth on infants, and a provisional patent on the mechanism of tolerance to stimulant medication (PATSMTA). Dr. Coghill worked for several pharmaceutical companies but had no disclosures relevant to this debate.

For children with attention-deficit/hyperactivity disorder, taking a weekend or summer break from methylphenidate may have some benefits. A drug “holiday” can help assess whether a drug is still useful and possibly help with drug tolerance, weight gain, and growth suppression. But drug holidays are not without their problems, Lily Hechtman, MD, FRCP, professor at the department of psychiatry, McGill University, Montreal, said during a session at the World Congress on ADHD – Virtual Event.

Ceasing a medication can have repercussions from a health and social standpoint, cautioned Dr. Hechtman, a presenter and moderator of the session, “Unsolved mysteries in the treatment of ADHD with psychostimulants.”

The rate of drug holidays is somewhere between 30% and 40% in ADHD patients. Patients have multiple reasons for taking them, said Dr. Hechtman. The American Academy of Child & Adolescent Psychology as well as the National Institute for Health and Clinical Excellence recommend this method to assess whether a medication is still necessary. Parents may opt for a drug holiday because most would prefer their children to take less medication.

A drug holiday can counteract some of the key side effects of stimulant medication such as decreased appetite and weight loss, and the moodiness and irritability that accompanies the medication, as well as sleep problems.

It may also be used to avoid drug tolerance, the need to increase dosage as medication continues. A 2002 study of 166 children and adolescents treated with methylphenidate revealed that 60% had developed drug tolerance. Drug tolerance increases with duration. “So, the longer the child is on medication, the more likely he or she will develop some drug tolerance,” said Dr. Hechtman.

It is hypothesized that a drug holiday results in the resensitization of the neurons in the brain because they aren’t exposed to the stimulation of dopamine release and dopamine exposure.

The minimum time a patient needs a drug holiday to deal with some drug tolerance is about a month. “Even if you have a drug holiday and your drug tolerance has been decreased, it can reoccur with increasing dosages, once medication resumes” after the holiday, said Dr. Hechtman.
 

The growth factor

A drug holiday can also address concerns about growth suppression. “Some studies show that drug holidays help with growth suppression and others do not,” said Dr. Hechtman.

The Multimodal Treatment of ADHD (MTA) study, which followed children with ADHD from childhood to adolescence into adulthood, offers some key insights on the effects of treatment on growth.

Over a 10-year period, “you could see that the rate of medication use decreased significantly with time” among participants, said Dr. Hechtman, a coauthor of the MTA research. Only 10% who began the study aged 7-9 years were still using stimulants 10 years later. Looking at short-term effects on growth among these children, those who never went on stimulants to begin with had no growth suppression at all, whereas those who underwent early and consistent treatment experienced the greatest growth suppression.

Comparatively, inconsistently medicated participants had less growth suppression than those who remained on medication. “They were pretty close to the controls,” said Dr. Hechtman.

These patterns continued in a 16-year follow-up, as these patients became adults. Based on the results in the inconsistently treated group, this suggests that drug holidays can limit the effects of growth suppression, at least to a certain extent, said Dr. Hechtman.

Other studies have yielded varying results on the impact of drug holidays on height and weight. “The evidence for the utility of drug holidays for medication side effects is there for decreased appetite and weight, but not so much for decreased height,” summarized Dr. Hechtman.

One recent study of 230 children by James Waxmonsky and colleagues that examined drug holidays on weekends and summers showed that drug holidays did increase weight but interestingly, not height. Older studies Dr. Hechtman cited had inconsistent results on height and weight gain and loss. A 2012 study suggested that drug holidays resulted in a slight improvement in appetite for both weekend and school holidays. But only 9% of the children in the sample (n = 51) saw their appetite return to normal levels.
 

‘Negative things can happen’

The downside of drug holidays is parents may rationalize that their child is doing fine without the medication, and discontinue it. The process of stopping and starting medication can lead to other problems. “Negative things can happen during drug holidays,” said Dr. Hechtman.

The large variability of doses over the weekend can result in rebound and side effects.

A child may go from a full dose, which could be 50-60 mg of stimulant to zero from Friday to Saturday. As a result they have a lot of rebound on that Saturday. Similarly, they go from zero on Sunday to full dose on the Monday, causing lots of side effects. “Also, they will never have a stable effective dose because of the roller-coaster effect of being on and off the drugs,” she noted.

The lack of consistency and accommodation to the side effects can lead to discontinuation of the medication.

Off medication, the child may be more accident prone or have more injuries. “Their behavior off the medication may be such that it leads to social problems,” Dr. Hechtman continued. Weekend activities that require medication such as homework or school projects, family or religious gatherings, or sports and social activities with family and peers may be affected. If the child is behaving poorly off the medication, they may be expelled from such activities. If it’s a summer drug holiday, they may get kicked out of camp or the swimming pool.

If the child’s condition is already worsening, and a drug holiday takes place on top of this, the child may experience a rebound or relapse, in which the condition looks a lot worse than it did with the drugs.
 

Do drug holidays matter?

Another session speaker, James Swanson, PhD, who noted that the “emergence of tolerance may limit and eventually undermine initial relative benefit” of stimulants, said there may be instances in which drug holidays may be impractical.

Given the poor adherence to ADHD medication, “most treated ADHD cases stop medication anyway and these patients do not have an opportunity for drug holidays,” he said in an interview.

“If tolerance does emerge, then for long-term treatment the concept of drug holiday seems difficult to evaluate to me,” said Dr. Swanson, director of the Child Development Center at the University of California, Irvine.

Planned medication breaks may not be a good way to evaluate efficacy unless it is performed under “double-blind” conditions, he offered. The MTA used an approach of switching between short periods of time, with and without medication. “We did this to compare medication to placebo and to compare doses of medication to optimize the short-term benefit,” said Dr. Swanson, a coauthor of the MTA study.

Dr. Hechtman receives funding from The Canadian Institutes of Health Research. Dr. Swanson has two patents: (PIXA4), which uses a “time-of-flight” camera to measure growth on infants, and a provisional patent on the mechanism of tolerance to stimulant medication (PATSMTA).

Delirium is a condition commonly exhibited by hospitalized patients and by those who are approaching the end of life.¹ Patients who experience a disturbance in attention that develops over a relatively short period and represents an acute change may have delirium.² Furthermore, there is often an additional cognitive disturbance, such as disorientation, memory deficit, language deficits, visuospatial deficit, or perception. Terminal delirium is defined as delirium that occurs in the dying process and implies that reversal is less likely.³ When death is anticipated, diagnostic workups are not recommended, and treatment of the physiologic abnormalities that contribute to delirium is generally ineffective.⁴

Background

Delirium is often underdiagnosed and undetected by the clinician. Some studies have shown that delirium is not detected in 22 to 50% of cases.⁵ Factors that contribute to the underdetection of delirium include preexisting dementia, older age, presence of visual or hearing impairment, and hypoactive presentation of delirium. Other possible reasons for nondetection of delirium are its fluctuating nature and lack of formal cognitive assessment as part of a routine screening across care settings.⁵ Another study found that 41% of health care providers (HCPs) felt that screening for delirium was burdensome.⁶

To date, there are no veteran-focused studies that investigate prevalence or risk factors for terminal delirium in US Department of Veterans Affairs (VA) long-term care hospice units. Most long-term care hospice units in the VA are in community living centers (CLCs) that follow regulatory guidelines for using antipsychotic medications. The Centers for Medicare and Medicaid Services state that if antipsychotics are prescribed, documentation must clearly show the indication for the antipsychotic medication, the multiple attempts to implement planned care, nonpharmacologic approaches, and ongoing evaluation of the effectiveness of these interventions.⁷ The symptoms of terminal delirium cause significant distress to patients, family and caregivers, and nursing staff. Literature suggests that delirium poses significant relational challenges for patients, families, and HCPs in end-of-life situations.^8,9 We hypothesize that the early identification of risk factors for the development of terminal delirium in this population may lead to increased use of nonpharmacologic measures to prevent terminal delirium, increase nursing vigilance for development of symptoms, and reduce symptom burden should terminal delirium develop.

Prevalence of delirium in the long-term care setting has ranged between 1.4 and 70.3%.¹⁰ The rate was found to be much higher in institutionalized populations compared with that of patients classified as at-home. In a study of the prevalence, severity, and natural history of neuropsychiatric syndromes in terminally ill veterans enrolled in community hospice, delirium was found to be present in only 4.1% on the initial visit and 42.5% during last visit. Also, more than half had at least 1 episode of delirium during the 90-day study period.¹¹ In a study of the prevalence of delirium in terminal cancer patients admitted to hospice, 80% experienced delirium in their final days.¹²

Risk factors for the development of delirium that have been identified in actively dying patients include bowel or bladder obstruction, fluid and electrolyte imbalances, suboptimal pain management, medication adverse effects and toxicity (eg, benzodiazepines, opioids, anticholinergics, and steroids), the addition of ≥ 3 medications, infection, hepatic and renal failure, poor glycemic control, hypoxia, and hematologic disturbances.^4,5,13 A high percentage of patients with a previous diagnosis of dementia were found to exhibit terminal delirium.¹⁴

There are 2 major subtypes of delirium: hyperactive and hypoactive.⁴ Patients with hypoactive delirium exhibit lethargy, reduced motor activity, lack of interest, and/or incoherent speech. There is currently little evidence to guide the treatment of hypoactive delirium. By contrast, hyperactive delirium is associated with hallucinations, agitation, heightened arousal, and inappropriate behavior. Many studies suggest both nonpharmacologic and pharmacologic treatment modalities for the treatment of hyperactive delirium.^4,13 Nonpharmacologic interventions may minimize the risk and severity of symptoms associated with delirium. Current guidelines recommend these interventions before pharmacologic treatment.⁴ Nonpharmacologic interventions include but are not limited to the following: engaging the patient in mentally stimulating activities; surrounding the patient with familiar materials (eg, photos); ensuring that all individuals identify themselves when they encounter a patient; minimizing the intensity of stimulation, providing family or volunteer presence, soft lighting and warm blankets; and ensuring the patient uses hearing aids and glasses if needed.^4,14

Although there are no US Food and Drug Administration-approved medications to treat hyperactive delirium, first-generation antipsychotics (eg, haloperidol, chlorpromazine) are considered the first-line treatment for patients exhibiting psychosis and psychomotor agitation.^3,4,14-16 In terminally ill patients, there is limited evidence from clinical trials to support the efficacy of drug therapy.¹⁴ One study showed lack of efficacy with hydration and opioid rotation.¹⁷ In terminally ill patients experiencing hyperactive delirium, there is a significant increased risk of muscle tension, myoclonic seizures, and distress to the patient, family, and caregiver.¹ Benzodiazepines can be considered first-line treatment for dying patients with terminal delirium in which the goals of treatment are to relieve muscle tension, ensure amnesia, reduce the risk of seizures, and decrease psychosis and agitation.^18,19 Furthermore, in patients with history of alcohol misuse who are experiencing terminal delirium, benzodiazepines also may be the preferred pharmacologic treatment.²⁰ Caution must be exercised with the use of benzodiazepines because they can also cause oversedation, increased confusion, and/or a paradoxical worsening of delirium.^3,4,14

Methods

This was a retrospective case-control study of patients who died in the Edward Hines Jr. Veterans Affairs Hospital CLC in Hines, Illinois, under the treating specialty nursing home hospice from October 1, 2013 to September 30, 2015. Due to the retrospective nature of this trial, the use of antipsychotics within the last 2 weeks of life was a surrogate marker for development of terminal delirium. Cases were defined as patients who were treated with antipsychotics for terminal delirium within the last 2 weeks of their lives. Controls were defined as patients who were not treated with antipsychotics for terminal delirium within the last 2 weeks of their lives. Living hospice patients and patients who were discharged from the CLC before death were excluded.

The goals of this study were to (1) determine risk factors in the VA CLC hospice veteran population for the development of terminal delirium; (2) evaluate documentation by the nursing staff of nonpharmacologic interventions and indications for antipsychotic use in the treatment of terminal delirium; and (3) examine the current usage patterns of antipsychotics for the treatment of terminal delirium.

Veterans’ medical records were reviewed from 2 weeks before death until the recorded death date. Factors that were assessed included age, war era of service, date of death, terminal diagnosis, time interval from cancer diagnosis to death, comorbid conditions, prescribed antipsychotic medications, and other medications potentially contributing to delirium. Nursing documentation was reviewed for indications for administration of antipsychotic medications and nonpharmacologic interventions used to mitigate the symptoms of terminal delirium.

Statistical analysis was conducted in SAS Version 9.3. Cases were compared with controls using univariate and multivariate statistics as appropriate. Comparisons for continuous variables (eg, age) were conducted with Student t tests. Categorical variables (eg, PTSD diagnosis) were compared using χ² analysis or Fisher exact test as appropriate. Variables with a P value < .1 in the univariate analysis were included in logistic regression models. Independent variables were removed from the models, using a backward selection process. Interaction terms were tested based on significance and clinical relevance. A P value < .05 was considered statistically significant.

Results

From October 1, 2013 to September 30, 2015, 307 patients were analyzed for inclusion in this study. Within this population, 186 received antipsychotic medications for the treatment of terminal delirium (cases), while 90 did not receive antipsychotics (controls). Of the 31 excluded patients, 13 were discharged to receive home hospice care, 11 were discharged to community nursing homes, 5 died in acute care units of Edward Hines, Jr. VA Hospital, and 2 died outside of the study period.

The mean age of all included patients was 75.5 years, and the most common terminal diagnosis was cancer, which occurred in 156 patients (56.5%) (Table 1). The baseline characteristics were similar between the cases and controls, including war era of veteran, terminal diagnosis, and comorbid conditions. The mean time between cancer diagnosis and death was not notably longer in the control group compared with that of the case group (25 vs 16 mo, respectively). There was no statistically significant difference in terminal diagnoses between cases and controls. Veterans in the control group spent more days (mean [SD]) in the hospice unit compared with veterans who experienced terminal delirium (48.5 [168.4] vs 28.2 [46.9]; P = .01). Patients with suspected infections were more likely found in the control group (P = .04; odds ratio [OR] = 1.70; 95% CI, 1.02-2.82).

Several risk factors for terminal delirium were identified in this veteran population. Veterans with a history of drug or alcohol abuse were found to be at a significantly higher risk for terminal delirium (P = .04; OR, 1.87; 95% CI, 1.03-3.37). As noted in previous studies, steroid use (P = .01; OR, 2.57; 95% CI, 1.26-5.22); opioids (P = .007; OR, 5.94; 95% CI, 1.54-22.99), and anticholinergic medications (P = .01; OR, 2.06; 95% CI, 1.21-3.52) also increased the risk of delirium (Table 2).

Discussion

Terminal delirium is experienced by many individuals in their last days to weeks of life. Symptoms can present as hyperactive (eg, agitation, hallucinations, heightened arousal) or hypoactive (lethargy, reduced motor activity, incoherent speech). Hyperactive terminal delirium is particularly problematic because it causes increased distress to the patient, family, and caregivers. Delirium can lead to safety concerns, such as fall risk, due to patients’ decreased insight into functional decline.

Many studies suggest both nonpharmacologic and pharmacologic treatments for nonterminal delirium that may also apply to terminal delirium. Nonpharmacologic methods, such as providing a quiet and familiar environment, relieving urinary retention or constipation, and attending to sensory deficits may help prevent or minimize delirium. Pharmacologic interventions, such as antipsychotics or benzodiazepines, may benefit when other modalities have failed to assuage distressing symptoms of delirium. Because hypoactive delirium is usually accompanied by somnolence and reduced motor activity, medication is most often administered to individuals with hyperactive delirium.

The VA provides long-term care hospice beds in their CLCs for veterans who are nearing end of life and have inadequate caregiver support for comprehensive end-of-life care in the home (Case Presentation). Because of their military service and other factors common in their life histories, they may have a unique set of characteristics that are predictive of developing terminal delirium. Awareness of the propensity for terminal delirium will allow for early identification of symptoms, timely initiation of nonpharmacologic interventions, and potentially a decreased need for use of antipsychotic medications.

Limitations

Limitations to the current study include hyperactive delirium that was misinterpreted and treated as pain; the probable underreporting of hypoactive delirium and associated symptoms; the use of antipsychotics as a surrogate marker for the development of terminal delirium; and lack of nursing documentation of assessment and interventions of terminal delirium. In addition, the total milligrams of antipsychotics administered per patient were not collected. Finally, there was the potential that other risk factors were not identified due to low numbers of veterans with certain diagnoses (eg, dementia).

Conclusions

Based on the findings in this study, several steps have been implemented to enhance the care of veterans under hospice care in this CLC: (1) Nurses providing direct patient care have been educated on the assessment by use of the mRASS and treatment of terminal delirium;²² (2) A hospice delirium note template has been created that details symptoms of terminal delirium, nonpharmacologic interventions, the use of antipsychotic medications if indicated, and the outcome of interventions; (3) Providers (eg, physician, advanced practice nurses) review each veteran’s medical history for the risk factors noted above; (4) Any risk factor(s) identified by this study will lead to a nursing order for delirium precautions, which requires completion of the delirium note template by nurses each shift.

The goal for this enhanced process is to identify veterans at risk for terminal delirium, observe changes that may indicate the onset of delirium, and intervene promptly to decrease symptom burden and improve quality of life and safety. Potentially, there will be less requirement for the use of antipsychotic medications to control the more severe symptoms of terminal delirium. A future study will evaluate the outcome of this enhanced process for the assessment and treatment of terminal delirium in this veteran population.

Most long-term care hospice units in the VA are in community living centers (CLCs) that follow regulatory guidelines for using antipsychotic medications. The Centers for Medicare and Medicaid Services state that if antipsychotics are prescribed, documentation must clearly show the indication for the antipsychotic medication, the multiple attempts to implement planned care, nonpharmacologic approaches, and ongoing evaluation of the effectiveness of these interventions.⁷ The symptoms of terminal delirium cause significant distress to patients, family and caregivers, and nursing staff. Literature suggests that delirium poses significant relational challenges for patients, families, and HCPs in end-of-life situations.^8,9 We hypothesize that the early identification of risk factors for the development of terminal delirium in this population may lead to increased use of nonpharmacologic measures to prevent terminal delirium, increase nursing vigilance for development of symptoms, and reduce symptom burden should terminal delirium develop.

Prevalence of delirium in the long-term care setting has ranged between 1.4 and 70.3%.¹⁰ The rate was found to be much higher in institutionalized populations compared with that of patients classified as at-home. In a study of the prevalence, severity, and natural history of neuropsychiatric syndromes in terminally ill veterans enrolled in community hospice, delirium was found to be present in only 4.1% on the initial visit and 42.5% during last visit. Also, more than half had at least 1 episode of delirium during the 90-day study period.¹¹ In a study of the prevalence of delirium in terminal cancer patients admitted to hospice, 80% experienced delirium in their final days.¹²

Risk factors for the development of delirium that have been identified in actively dying patients include bowel or bladder obstruction, fluid and electrolyte imbalances, suboptimal pain management, medication adverse effects and toxicity (eg, benzodiazepines, opioids, anticholinergics, and steroids), the addition of ≥ 3 medications, infection, hepatic and renal failure, poor glycemic control, hypoxia, and hematologic disturbances.^4,5,13 A high percentage of patients with a previous diagnosis of dementia were found to exhibit terminal delirium.¹⁴

There are 2 major subtypes of delirium: hyperactive and hypoactive.⁴ Patients with hypoactive delirium exhibit lethargy, reduced motor activity, lack of interest, and/or incoherent speech. There is currently little evidence to guide the treatment of hypoactive delirium. By contrast, hyperactive delirium is associated with hallucinations, agitation, heightened arousal, and inappropriate behavior. Many studies suggest both nonpharmacologic and pharmacologic treatment modalities for the treatment of hyperactive delirium.^4,13 Nonpharmacologic interventions may minimize the risk and severity of symptoms associated with delirium. Current guidelines recommend these interventions before pharmacologic treatment.⁴ Nonpharmacologic interventions include but are not limited to the following: engaging the patient in mentally stimulating activities; surrounding the patient with familiar materials (eg, photos); ensuring that all individuals identify themselves when they encounter a patient; minimizing the intensity of stimulation, providing family or volunteer presence, soft lighting and warm blankets; and ensuring the patient uses hearing aids and glasses if needed.^4,14

Although there are no US Food and Drug Administration-approved medications to treat hyperactive delirium, first-generation antipsychotics (eg, haloperidol, chlorpromazine) are considered the first-line treatment for patients exhibiting psychosis and psychomotor agitation.^3,4,14-16 In terminally ill patients, there is limited evidence from clinical trials to support the efficacy of drug therapy.¹⁴ One study showed lack of efficacy with hydration and opioid rotation.¹⁷ In terminally ill patients experiencing hyperactive delirium, there is a significant increased risk of muscle tension, myoclonic seizures, and distress to the patient, family, and caregiver.¹ Benzodiazepines can be considered first-line treatment for dying patients with terminal delirium in which the goals of treatment are to relieve muscle tension, ensure amnesia, reduce the risk of seizures, and decrease psychosis and agitation.^18,19 Furthermore, in patients with history of alcohol misuse who are experiencing terminal delirium, benzodiazepines also may be the preferred pharmacologic treatment.²⁰ Caution must be exercised with the use of benzodiazepines because they can also cause oversedation, increased confusion, and/or a paradoxical worsening of delirium.^3,4,14

Methods

This was a retrospective case-control study of patients who died in the Edward Hines Jr. Veterans Affairs Hospital CLC in Hines, Illinois, under the treating specialty nursing home hospice from October 1, 2013 to September 30, 2015. Due to the retrospective nature of this trial, the use of antipsychotics within the last 2 weeks of life was a surrogate marker for development of terminal delirium. Cases were defined as patients who were treated with antipsychotics for terminal delirium within the last 2 weeks of their lives. Controls were defined as patients who were not treated with antipsychotics for terminal delirium within the last 2 weeks of their lives. Living hospice patients and patients who were discharged from the CLC before death were excluded.

The goals of this study were to (1) determine risk factors in the VA CLC hospice veteran population for the development of terminal delirium; (2) evaluate documentation by the nursing staff of nonpharmacologic interventions and indications for antipsychotic use in the treatment of terminal delirium; and (3) examine the current usage patterns of antipsychotics for the treatment of terminal delirium.

Veterans’ medical records were reviewed from 2 weeks before death until the recorded death date. Factors that were assessed included age, war era of service, date of death, terminal diagnosis, time interval from cancer diagnosis to death, comorbid conditions, prescribed antipsychotic medications, and other medications potentially contributing to delirium. Nursing documentation was reviewed for indications for administration of antipsychotic medications and nonpharmacologic interventions used to mitigate the symptoms of terminal delirium.

Statistical analysis was conducted in SAS Version 9.3. Cases were compared with controls using univariate and multivariate statistics as appropriate. Comparisons for continuous variables (eg, age) were conducted with Student t tests. Categorical variables (eg, PTSD diagnosis) were compared using χ² analysis or Fisher exact test as appropriate. Variables with a P value < .1 in the univariate analysis were included in logistic regression models. Independent variables were removed from the models, using a backward selection process. Interaction terms were tested based on significance and clinical relevance. A P value < .05 was considered statistically significant.

Results

From October 1, 2013 to September 30, 2015, 307 patients were analyzed for inclusion in this study. Within this population, 186 received antipsychotic medications for the treatment of terminal delirium (cases), while 90 did not receive antipsychotics (controls). Of the 31 excluded patients, 13 were discharged to receive home hospice care, 11 were discharged to community nursing homes, 5 died in acute care units of Edward Hines, Jr. VA Hospital, and 2 died outside of the study period.

The mean age of all included patients was 75.5 years, and the most common terminal diagnosis was cancer, which occurred in 156 patients (56.5%) (Table 1). The baseline characteristics were similar between the cases and controls, including war era of veteran, terminal diagnosis, and comorbid conditions. The mean time between cancer diagnosis and death was not notably longer in the control group compared with that of the case group (25 vs 16 mo, respectively). There was no statistically significant difference in terminal diagnoses between cases and controls. Veterans in the control group spent more days (mean [SD]) in the hospice unit compared with veterans who experienced terminal delirium (48.5 [168.4] vs 28.2 [46.9]; P = .01). Patients with suspected infections were more likely found in the control group (P = .04; odds ratio [OR] = 1.70; 95% CI, 1.02-2.82).

Several risk factors for terminal delirium were identified in this veteran population. Veterans with a history of drug or alcohol abuse were found to be at a significantly higher risk for terminal delirium (P = .04; OR, 1.87; 95% CI, 1.03-3.37). As noted in previous studies, steroid use (P = .01; OR, 2.57; 95% CI, 1.26-5.22); opioids (P = .007; OR, 5.94; 95% CI, 1.54-22.99), and anticholinergic medications (P = .01; OR, 2.06; 95% CI, 1.21-3.52) also increased the risk of delirium (Table 2).

Discussion

Terminal delirium is experienced by many individuals in their last days to weeks of life. Symptoms can present as hyperactive (eg, agitation, hallucinations, heightened arousal) or hypoactive (lethargy, reduced motor activity, incoherent speech). Hyperactive terminal delirium is particularly problematic because it causes increased distress to the patient, family, and caregivers. Delirium can lead to safety concerns, such as fall risk, due to patients’ decreased insight into functional decline.

Many studies suggest both nonpharmacologic and pharmacologic treatments for nonterminal delirium that may also apply to terminal delirium. Nonpharmacologic methods, such as providing a quiet and familiar environment, relieving urinary retention or constipation, and attending to sensory deficits may help prevent or minimize delirium. Pharmacologic interventions, such as antipsychotics or benzodiazepines, may benefit when other modalities have failed to assuage distressing symptoms of delirium. Because hypoactive delirium is usually accompanied by somnolence and reduced motor activity, medication is most often administered to individuals with hyperactive delirium.

The VA provides long-term care hospice beds in their CLCs for veterans who are nearing end of life and have inadequate caregiver support for comprehensive end-of-life care in the home (Case Presentation). Because of their military service and other factors common in their life histories, they may have a unique set of characteristics that are predictive of developing terminal delirium. Awareness of the propensity for terminal delirium will allow for early identification of symptoms, timely initiation of nonpharmacologic interventions, and potentially a decreased need for use of antipsychotic medications.

Limitations

Limitations to the current study include hyperactive delirium that was misinterpreted and treated as pain; the probable underreporting of hypoactive delirium and associated symptoms; the use of antipsychotics as a surrogate marker for the development of terminal delirium; and lack of nursing documentation of assessment and interventions of terminal delirium. In addition, the total milligrams of antipsychotics administered per patient were not collected. Finally, there was the potential that other risk factors were not identified due to low numbers of veterans with certain diagnoses (eg, dementia).

Conclusions

Based on the findings in this study, several steps have been implemented to enhance the care of veterans under hospice care in this CLC: (1) Nurses providing direct patient care have been educated on the assessment by use of the mRASS and treatment of terminal delirium;²² (2) A hospice delirium note template has been created that details symptoms of terminal delirium, nonpharmacologic interventions, the use of antipsychotic medications if indicated, and the outcome of interventions; (3) Providers (eg, physician, advanced practice nurses) review each veteran’s medical history for the risk factors noted above; (4) Any risk factor(s) identified by this study will lead to a nursing order for delirium precautions, which requires completion of the delirium note template by nurses each shift.

The goal for this enhanced process is to identify veterans at risk for terminal delirium, observe changes that may indicate the onset of delirium, and intervene promptly to decrease symptom burden and improve quality of life and safety. Potentially, there will be less requirement for the use of antipsychotic medications to control the more severe symptoms of terminal delirium. A future study will evaluate the outcome of this enhanced process for the assessment and treatment of terminal delirium in this veteran population.

Delirium is a condition commonly exhibited by hospitalized patients and by those who are approaching the end of life.¹ Patients who experience a disturbance in attention that develops over a relatively short period and represents an acute change may have delirium.² Furthermore, there is often an additional cognitive disturbance, such as disorientation, memory deficit, language deficits, visuospatial deficit, or perception. Terminal delirium is defined as delirium that occurs in the dying process and implies that reversal is less likely.³ When death is anticipated, diagnostic workups are not recommended, and treatment of the physiologic abnormalities that contribute to delirium is generally ineffective.⁴

Background

Delirium is often underdiagnosed and undetected by the clinician. Some studies have shown that delirium is not detected in 22 to 50% of cases.⁵ Factors that contribute to the underdetection of delirium include preexisting dementia, older age, presence of visual or hearing impairment, and hypoactive presentation of delirium. Other possible reasons for nondetection of delirium are its fluctuating nature and lack of formal cognitive assessment as part of a routine screening across care settings.⁵ Another study found that 41% of health care providers (HCPs) felt that screening for delirium was burdensome.⁶

The composition of street drugs like heroin and cocaine are changing. According to a new analysis, almost all contain at least one toxic adulterant, and many contain a plethora. Most adulterants have pharmacologic activities and toxicities. Their presence has added impact in the context of the COVID-19 pandemic, since some may cause a drastic drop in white blood cells that could leave drug users more vulnerable to infection.

“It’s remarkable that we just forgot to notice, in the horrendous transition from prescription opioid epidemic to the illicit opioid and psychostimulant epidemics, that we would have to pay special attention to what the medications are in the drugs that the person was exposed to – and for how long,” said Mark S. Gold, MD, a coauthor of the review.

The analysis showed that adulterants include new psychoactive substances, industrial compounds, fungicides, veterinary medications, and various impurities. In addition, other various medications are being found in street drugs, such as antipsychotics, antidepressants, anxiolytics, antihistamines, anthelmintics, anesthetics, anti-inflammatory agents, antipyretics, analgesics, antispasmodics, antiarrhythmics, antimalarials, bronchodilators, decongestants, expectorants, muscle relaxers, natural/synthetic hallucinogens, and sedatives.

Illicit drugs are by nature manufactured without Food and Drug Administration oversight, and it is becoming increasingly common that substances like leftover medicines and other active drugs are added to illicit drug batches to add weight, said Dr. Gold, a professor at Washington University,St. Louis. The study appeared in Current Psychopharmacology.
 

Effects of adulterants ‘terrifying’

The findings of adulterants and their consequences are concerning, according to Jean Lud Cadet, MD, who was asked to comment on the findings. “The blood dysplasia, the pulmonary problems that some of those adulterants can cause – it’s actually terrifying, to put it bluntly,” said Dr. Cadet, who is a senior investigator and chief of the Molecular Neuropsychiatry Research Branch at the National Institute on Drug Abuse.

Before 2000, street drugs were generally diluted with comparatively benign substances such as caffeine, sugars, or lidocaine. Drugs like phenacetin, levamisole, acetaminophen, and diltiazem began to appear in heroin and cocaine in the late 1990s, and by 2010, more powerful adulterants like fentanyl, ketamine, and quetiapine became common. Adulterants can lead to a range of clinical effects, including renal and liver problems, blood disorders, infections, respiratory depression, and cardiac arrest.

In 2015, the U.S. Department of State partnered with the Colombo Plan, an international organization based in Sri Lanka, to use field spectroscopy to detect toxins directly in cocaine and heroin samples found in Argentina, Brazil, Ecuador, Peru, Sri Lanka, Thailand, Honduras, Guatemala, Mexico, Colombia, and South Africa. They found a range of adulterants such as aminopyrine, diltiazem, metamizole, levamisole, and phenacetin.

A similar project with 431 heroin and cocaine samples from Vermont and Kentucky found that 69% of samples had five or more controlled drugs, toxic adulterants, or impurities. About 15% had nine or more, and 95% of samples had at least one toxic adulterant.

In the midst of the COVID-19 pandemic, these adulterants take on even greater significance. Individuals with substance use disorders often have other health conditions that can make them more vulnerable to viral infections, and this could be exacerbated by the effects of adulterants on white blood cells or other systems. The pandemic has also had an indirect effect by causing a shortage of street drugs. During production shortages, traffickers might boost potency by adding more cutting agents and adulterants. As a result, COVID-19 and opioid addiction tend to reinforce each other.

“The clinical message would be that our [substance use] patients will contract infectious disease and need to be prioritized for [COVID-19] vaccination,” said Dr. Gold.

The findings came as a surprise to Dr. Cadet, and that illustrates a need to publicize the presence of adulterants in street drugs.

“If I wasn’t aware of many of these, then the general public is also not going to be aware of them,” Dr. Cadet said. “Scientists, including myself, and government agencies need to do a better job [of communicating this issue].”

The study references individuals with substance use disorder, but Dr. Cadet cautioned that anyone who uses street drugs, even once or twice, could be a victim of adulterants. “You don’t need to have met criteria for diagnosis in order to suffer the consequences.”

The study had no funding. Dr. Gold and Dr. Cadet have no relevant financial disclosures.

In addition, other various medications are being found in street drugs, such as antipsychotics, antidepressants, anxiolytics, antihistamines, anthelmintics, anesthetics, anti-inflammatory agents, antipyretics, analgesics, antispasmodics, antiarrhythmics, antimalarials, bronchodilators, decongestants, expectorants, muscle relaxers, natural/synthetic hallucinogens, and sedatives.

Illicit drugs are by nature manufactured without Food and Drug Administration oversight, and it is becoming increasingly common that substances like leftover medicines and other active drugs are added to illicit drug batches to add weight, said Dr. Gold, a professor at Washington University,St. Louis. The study appeared in Current Psychopharmacology.
 

Effects of adulterants ‘terrifying’

The findings of adulterants and their consequences are concerning, according to Jean Lud Cadet, MD, who was asked to comment on the findings. “The blood dysplasia, the pulmonary problems that some of those adulterants can cause – it’s actually terrifying, to put it bluntly,” said Dr. Cadet, who is a senior investigator and chief of the Molecular Neuropsychiatry Research Branch at the National Institute on Drug Abuse.

Before 2000, street drugs were generally diluted with comparatively benign substances such as caffeine, sugars, or lidocaine. Drugs like phenacetin, levamisole, acetaminophen, and diltiazem began to appear in heroin and cocaine in the late 1990s, and by 2010, more powerful adulterants like fentanyl, ketamine, and quetiapine became common. Adulterants can lead to a range of clinical effects, including renal and liver problems, blood disorders, infections, respiratory depression, and cardiac arrest.

In 2015, the U.S. Department of State partnered with the Colombo Plan, an international organization based in Sri Lanka, to use field spectroscopy to detect toxins directly in cocaine and heroin samples found in Argentina, Brazil, Ecuador, Peru, Sri Lanka, Thailand, Honduras, Guatemala, Mexico, Colombia, and South Africa. They found a range of adulterants such as aminopyrine, diltiazem, metamizole, levamisole, and phenacetin.

A similar project with 431 heroin and cocaine samples from Vermont and Kentucky found that 69% of samples had five or more controlled drugs, toxic adulterants, or impurities. About 15% had nine or more, and 95% of samples had at least one toxic adulterant.

In the midst of the COVID-19 pandemic, these adulterants take on even greater significance. Individuals with substance use disorders often have other health conditions that can make them more vulnerable to viral infections, and this could be exacerbated by the effects of adulterants on white blood cells or other systems. The pandemic has also had an indirect effect by causing a shortage of street drugs. During production shortages, traffickers might boost potency by adding more cutting agents and adulterants. As a result, COVID-19 and opioid addiction tend to reinforce each other.

“The clinical message would be that our [substance use] patients will contract infectious disease and need to be prioritized for [COVID-19] vaccination,” said Dr. Gold.

The findings came as a surprise to Dr. Cadet, and that illustrates a need to publicize the presence of adulterants in street drugs.

“If I wasn’t aware of many of these, then the general public is also not going to be aware of them,” Dr. Cadet said. “Scientists, including myself, and government agencies need to do a better job [of communicating this issue].”

The study references individuals with substance use disorder, but Dr. Cadet cautioned that anyone who uses street drugs, even once or twice, could be a victim of adulterants. “You don’t need to have met criteria for diagnosis in order to suffer the consequences.”

The study had no funding. Dr. Gold and Dr. Cadet have no relevant financial disclosures.

A new study finds that alpha2-adrenergic agonists may be of benefit and have fewer side effects than stimulant medications for the treatment of attention-deficit/hyperactivity disorder in preschool-age children.

The study was published online May 4 in JAMA.

As part of a retrospective analysis, Elizabeth Harstad, MD, MPH, of Boston Children’s Hospital and colleagues evaluated health record data from 497 preschool-age children with ADHD across seven developmental-behavioral pediatric practices in the United States. Children included in the evaluation were younger than 6 years and were treated for ADHD between Jan. 1, 2013, and July 1, 2017, with either an alpha2-adrenergic agonist or a stimulant.

Overall, 175 children (35%) were prescribed an alpha2-adrenergic agonist (most often guanfacine) as first-line ADHD medication, and 322 children (65%) were prescribed a stimulant (most often a methylphenidate-based preparation). Before any medication regimens were initiated, 62% of children received behavioral therapy.

“These findings suggest that for some children there may be a concern about either how well a stimulant will work or how well a stimulant will be tolerated that is leading clinicians to instead prescribe an alpha2-adrenergic agonist as the first medication tried,” Dr. Harstad said in an interview.

Clinical improvement was noted in 66% of children treated with alpha2-adrenergic agonists (95% confidence interval, 57.5%-73.9%) and in 78% of children treated with stimulants (95% CI, 72.4%-83.4%).

Most adverse effects were more common among children who received stimulants than among those who received alpha2-adrenergic agonists. These adverse effects included difficulty falling asleep (21% vs. 11%), decreased appetite (38% vs. 7%), increased stomachaches (13% vs. 5%), and increased skin picking/repetitive behaviors (11% vs. 5%). Only daytime sleepiness was more frequent among children who received an alpha2-adrenergic agonist rather than a stimulant (38% vs. 3%).

“We also found that for the youngest children (<4 years old), those initiated on alpha2-adrenergic agonists stayed on these medications longer than those initiated on stimulants, which may indicate that they are better tolerated, although more research is needed to confirm this,” Dr. Harstad said.

“While our study focused on how well medications work and how well they are tolerated when used to treat preschool-age children with ADHD, it is important to remember that behavioral therapy is recommended as first-line treatment for ADHD in preschool-age children, not medication,” Dr. Harstad added.

Mark Wolraich, MD, of the University of Oklahoma, echoed that sentiment. “The article mentions that behavioral interventions, in the form of parent training in behavior management, is an effective first-line treatment” and, per the American Academy of Pediatrics guidelines, “is the first line of treatment recommended for preschool-age children before medication should be considered.”

Dr. Wolraich also noted that “neither drug has official FDA [U.S. Food and Drug Administration] approval in this age group” but that “methylphenidate comes the closest to having met the FDA requirements for approval in this age group, which is why the AAP guidelines recommended its use if parent training in behavior management is not sufficient.”

Although Dr. Harstad and colleagues note that the study included a large and diverse sample size from across the United States, they acknowledge that “further research, including from randomized clinical trials, is needed to assess comparative effectiveness of alpha2-adrenergic agonists versus stimulants.”

Funding for the study was provided through a cooperative agreement with the Maternal and Child Health Bureau, the Health Resources and Services Administration, and the U.S. Department of Health & Human Services. Dr. Harstad has reported receiving reported receiving compensation for serving as a medical reviewer for Understood.org and grant funding from the Palmer Family Fund for Autism Research to conduct research related to autism spectrum disorder at Boston Children’s Hospital. Disclosures for the other authors are listed in the original article. Dr. Wolraich has disclosed no relevant financial relationships.

An online, culturally based peer support group that uses theater and other creative outlets is helping Asian Americans cope with the COVID-19 pandemic, new research shows.

The findings of the qualitative study suggest that the program could be a model to support the mental health of other minority community groups during the COVID pandemic and beyond, say investigators from the Yale University Child Study Center, New Haven, Conn.

The Yale Compassionate Home, Action Together (CHATogether) group was created to promote emotional wellness among Asian American youth, young adults, and their families.

Early in the pandemic, it expanded its purpose to serve as a COVID-19 support group. Through social media outreach, CHATogether encourages members to cope with COVID-19 by using productive and creative outlets.

“We are a community education program serving Asian American families,” said Eunice Yuen, MD, PhD, the program’s founder and director, who is with the Yale University Child Study Center.

“We started when the pandemic began, and we realized the unique emotional distress shared among Asian American families, such as family conflict and xenophobic attacks,” said Dr. Yuen.

She discussed the program at the annual meeting of the American Psychiatric Association, which was held as a virtual live event.
 

Skits, role playing

CHATogether groups consist of people with similar experiences and challenges who support each other through weekly online group meetings, she explained.

Group members work together to create family conflict scenarios and role-play dialogues on topics amplified during the COVID-19 pandemic, such as cross-cultural challenges among Asian Americans, academic expectations in home schooling, and Black Lives Matter and LGBTQ conflicts within Asian families.

Group members create skits that are based on their personal experiences and that allow them to work through their own internal conflicts and gain a sense of agency, said Dr. Yuen.

“CHATogether is really the interface of mental health, art, and theater, and we’re trying to create a vehicle that can be a lighthearted way for people to talk about mental health, especially for Asian American families,” said Dr. Yuen.

Preliminary results from a focus group with 10 CHATogether members who joined the program since the pandemic started identified four major ways in which the program has had a positive impact on the mental health and well-being of participants:

• It provides a safe and supportive environment, strengthens bonds between members, and increases the sense of belonging, thus encouraging engagement.
• It provides structural consistency/stability through regular meetings and consistent group functions. Weekly meetings provide a sense of control and hope in the midst of uncertainty during periods of sheltering in place.
• Through adapting the group to virtual platforms, group members experience the inherent strengths of a growth mindset and cognitive flexibility when facing challenges.
• It supports healthy coping skills through sublimation and altruism.

Looking ahead, Dr. Yuen said, the team plans to investigate the validity and effectiveness of this model and to expand the group to include other minorities, school educators, and medical education for trainees and medical students.

Commenting on the program, briefing moderator Jeffrey Borenstein, MD, president and CEO of the Brain and Behavior Research Foundation and editor-in-chief of Psychiatric News, described the initiative as a “great project that serves as a model that can be used not only for Asian Americans but for other groups.

“I think the key to it is that cultural sensitivity that we need to really take into account and cultural differences among people in order to best engage them and help support them. I think this program does that beautifully,” said Dr. Borenstein.

The work was supported by the APA’s Substance Abuse and Mental Health Services Administration Minority Fellowship, which provides a 1-year fellowship to psychiatry residents committed to addressing minority psychiatric mental health issues. Dr. Yuen and Dr. Borenstein disclosed no relevant financial relationships.

Current models used to predict suicide risk fall short for racialized populations including Black, Indigenous, and people of color (BIPOC), new research shows.

Investigators developed two suicide prediction models to examine whether these types of tools are accurate in their predictive abilities, or whether they are flawed.

They found both prediction models failed to identify high-risk BIPOC individuals. In the first model, nearly half of outpatient visits followed by suicide were identified in White patients versus only 7% of visits followed by suicide in BIPOC patients. The second model had a sensitivity of 41% for White patients, but just 3% for Black patients and 7% for American Indian/Alaskan Native patients.

Racial inequities

Suicide risk prediction models have been “developed and validated in several settings” and are now in regular use at the Veterans Health Administration, HealthPartners, and Kaiser Permanente, the authors wrote.

But the performance of suicide risk prediction models, while accurate in the overall population, “remains unexamined” in particular subpopulations, they noted.

“Health records data reflect existing racial and ethnic inequities in health care access, quality, and outcomes; and prediction models using health records data may perpetuate these disparities by presuming that past healthcare patterns accurately reflect actual needs,” Dr. Coley said.

Dr. Coley and associates “wanted to make sure that any suicide prediction model we implemented in clinical care reduced health disparities rather than exacerbated them.”

To investigate, researchers examined all outpatient mental health visits to seven large integrated health care systems by patients 13 years and older (n = 13,980,570 visits by 1,422,534 patients; 64% female, mean age, 42 years). The study spanned from Jan. 1, 2009, to Sept. 30, 2017, with follow-up through Dec. 31, 2017.

In particular, researchers looked at suicides that took place within 90 days following the outpatient visit.

Researchers used two prediction models: logistic regression with LASSO (Least Absolute Shrinkage and Selection Operator) variable selection and random forest technique, a “tree-based method that explores interactions between predictors (including those with race and ethnicity) in estimating probability of an outcome.”

The models considered prespecified interactions between predictors, including prior diagnoses, suicide attempts, and PHQ-9 [Patient Health Questionnaire–9] responses, and race and ethnicity data.

Researchers evaluated performance of the prediction models in the overall validation set and within subgroups defined by race/ethnicity.

The area under the curve measured model discrimination, and sensitivity was estimated for global and race/ethnicity-specific thresholds.
 

‘Unacceptable’ scenario

Within the total population, there were 768 deaths by suicide within 90 days of 3,143 visits. Suicide rates were highest for visits by patients with no recorded race/ethnicity, followed by visits by Asian, White, American Indian/Alaskan Native, Hispanic, and Black patients.

Both models showed “high” AUC sensitivity for White, Hispanic, and Asian patients but “poor” AUC sensitivity for BIPOC and patients without recorded race/ethnicity, the authors reported.

“Implementation of prediction models has to be considered in the broader context of unmet health care needs,” said Dr. Coley.

“In our specific example of suicide prediction, BIPOC populations already face substantial barriers in accessing quality mental health care and, as a result, have poorer outcomes, and using either of the suicide prediction models examined in our study will provide less benefit to already-underserved populations and widen existing care gaps,” a scenario Dr. Coley said is “unacceptable.”

“We must insist that new technologies and methods be used to reduce racial and ethnic inequities in care, not exacerbate them,” she added.
 

Biased algorithms

Commenting on the study, Jonathan Singer, PhD, LCSW, associate professor at Loyola University, Chicago, described it as an “important contribution because it points to a systemic problem and also to the fact that the algorithms we create are biased, created by humans, and humans are biased.”

Although the study focused on the health care system, Dr. Singer believes the findings have implications for individual clinicians.

“If clinicians may be biased against identifying suicide risk in Black and Native American patients, they may attribute suicidal risk to something else. For example, we know that in Black Americans, expressions of intense emotions are oftentimes interpreted as aggression or being threatening, as opposed to indicators of sadness or fear,” noted Dr. Singer, who is also president of the American Academy of Suicidology and was not involved with the study,

“Clinicians who misinterpret these intense emotions are less likely to identify a Black client or patient who is suicidal,” Dr. Singer said.

The research was supported by the Mental Health Research Network from the National Institute of Mental Health. Dr. Coley has reported receiving support through a grant from the Agency for Healthcare Research and Quality. Dr. Singer reported no relevant financial relationships.

“We must insist that new technologies and methods be used to reduce racial and ethnic inequities in care, not exacerbate them,” she added.
 

Biased algorithms

Commenting on the study, Jonathan Singer, PhD, LCSW, associate professor at Loyola University, Chicago, described it as an “important contribution because it points to a systemic problem and also to the fact that the algorithms we create are biased, created by humans, and humans are biased.”

Although the study focused on the health care system, Dr. Singer believes the findings have implications for individual clinicians.

“If clinicians may be biased against identifying suicide risk in Black and Native American patients, they may attribute suicidal risk to something else. For example, we know that in Black Americans, expressions of intense emotions are oftentimes interpreted as aggression or being threatening, as opposed to indicators of sadness or fear,” noted Dr. Singer, who is also president of the American Academy of Suicidology and was not involved with the study,

“Clinicians who misinterpret these intense emotions are less likely to identify a Black client or patient who is suicidal,” Dr. Singer said.

The research was supported by the Mental Health Research Network from the National Institute of Mental Health. Dr. Coley has reported receiving support through a grant from the Agency for Healthcare Research and Quality. Dr. Singer reported no relevant financial relationships.

Current models used to predict suicide risk fall short for racialized populations including Black, Indigenous, and people of color (BIPOC), new research shows.

Investigators developed two suicide prediction models to examine whether these types of tools are accurate in their predictive abilities, or whether they are flawed.

They found both prediction models failed to identify high-risk BIPOC individuals. In the first model, nearly half of outpatient visits followed by suicide were identified in White patients versus only 7% of visits followed by suicide in BIPOC patients. The second model had a sensitivity of 41% for White patients, but just 3% for Black patients and 7% for American Indian/Alaskan Native patients.

Racial inequities

Suicide risk prediction models have been “developed and validated in several settings” and are now in regular use at the Veterans Health Administration, HealthPartners, and Kaiser Permanente, the authors wrote.

But the performance of suicide risk prediction models, while accurate in the overall population, “remains unexamined” in particular subpopulations, they noted.

“Health records data reflect existing racial and ethnic inequities in health care access, quality, and outcomes; and prediction models using health records data may perpetuate these disparities by presuming that past healthcare patterns accurately reflect actual needs,” Dr. Coley said.

Dr. Coley and associates “wanted to make sure that any suicide prediction model we implemented in clinical care reduced health disparities rather than exacerbated them.”

To investigate, researchers examined all outpatient mental health visits to seven large integrated health care systems by patients 13 years and older (n = 13,980,570 visits by 1,422,534 patients; 64% female, mean age, 42 years). The study spanned from Jan. 1, 2009, to Sept. 30, 2017, with follow-up through Dec. 31, 2017.

In particular, researchers looked at suicides that took place within 90 days following the outpatient visit.

Researchers used two prediction models: logistic regression with LASSO (Least Absolute Shrinkage and Selection Operator) variable selection and random forest technique, a “tree-based method that explores interactions between predictors (including those with race and ethnicity) in estimating probability of an outcome.”

The models considered prespecified interactions between predictors, including prior diagnoses, suicide attempts, and PHQ-9 [Patient Health Questionnaire–9] responses, and race and ethnicity data.

Researchers evaluated performance of the prediction models in the overall validation set and within subgroups defined by race/ethnicity.

The area under the curve measured model discrimination, and sensitivity was estimated for global and race/ethnicity-specific thresholds.
 

‘Unacceptable’ scenario

Within the total population, there were 768 deaths by suicide within 90 days of 3,143 visits. Suicide rates were highest for visits by patients with no recorded race/ethnicity, followed by visits by Asian, White, American Indian/Alaskan Native, Hispanic, and Black patients.

Both models showed “high” AUC sensitivity for White, Hispanic, and Asian patients but “poor” AUC sensitivity for BIPOC and patients without recorded race/ethnicity, the authors reported.

“Implementation of prediction models has to be considered in the broader context of unmet health care needs,” said Dr. Coley.

“In our specific example of suicide prediction, BIPOC populations already face substantial barriers in accessing quality mental health care and, as a result, have poorer outcomes, and using either of the suicide prediction models examined in our study will provide less benefit to already-underserved populations and widen existing care gaps,” a scenario Dr. Coley said is “unacceptable.”

The past year presented unprecedented challenges for many. In addition, mental health services have also been stretched to capacity. Anecdotally, some hospitals and emergency departments note that more youth have been presenting in mental health crises, and the severity of symptoms has also been higher. Safety planning is important, including working with patients to identify skills they can use in distress. Even those who do not experience suicidal thoughts may struggle with dysregulation or may use coping strategies that may not be the healthiest in the long term.

Within my practice, I see some families who are still waiting for an available therapist, or some may not wish to participate in therapy despite its being recommended. For these families, supporting them in using strategies that they may be willing and able to use in the moment to help them get through the moment of crisis can been helpful:
 

Case example (identifying details have been changed)

Emily is a 17-year-old girl who has a history of generalized anxiety disorder and obsessive-compulsive disorder. She has had multiple medication trials and a course of cognitive behavioral therapy when younger, with significant improvement in symptoms. She returns to clinic because of increased anxiety related to stressors of the pandemic. She wishes to not return to therapy because of feeling that she received maximal benefit and that further sessions would not be fruitful. However, she struggles with identifying what skills she can use, and her anxiety heightens significantly to near-panic and hyperventilating with even cursory exploration of triggers for her symptoms. Medications are also discussed during this appointment, and it is noted that it may take some time to see therapeutic effect. Of note, she reports no acute safety concerns. She has engaged in skin picking. No reported substance use. As she hyperventilates, she was asked to identify items in the room matching the colors of the rainbow in order. She was able to quickly do this, and then was asked to do it again. Afterward, she noted feeling much less anxious because it distracted her from her thoughts.

Distress tolerance skills can be very helpful to navigate getting through a crisis. When under stress, some may be more likely to engage in behaviors that are not helpful in the long term such as using avoidance; procrastinating; consuming tobacco, alcohol, or other substances; spending too much time on screens; or engaging in self-harm behaviors. While some of these activities may be okay in moderation, others are always harmful. At times, when encouraging patients to use skills with which they may be more familiar, e.g., deep breathing, progressive muscle relaxation, the response may be, “these don’t work!” It can be important to distinguish that the function of these skills is not to make someone feel good or to eliminate the stressor, but to “take some of the edge off” so they are less likely to slide into problematic behaviors. It can be beneficial to have multiple tools at one’s disposal because not all skills will always be effective or available.

TIPP skills (temperature, intense exercise, paced breathing, progressive muscle relaxation) are distress tolerance skills from dialectical behavioral therapy (DBT),¹ which was initially developed to treat individuals with borderline personality disorder. More recently, the therapy modality has been applied to individuals who may struggle with emotion regulation for a variety of reasons. TIPP skills work quickly (within seconds to minutes) with the aim to decrease physiological arousal. They do not require a lot of thinking, and many are portable or easy to use. Given the speed of effect, these skills can also be used in lieu of p.r.n. medications or patients can be counseled about trying these instead of turning to substance use. The effect is brief (5-20 minutes), although this may lower the affective temperature sufficiently for someone to get through the intense moment or to be able to then utilize other skills that may require more cognitive reserves.
 

T – Temperature

Holding one’s breath and placing one’s face in cold water (above 50°) for 10-20 seconds to stimulate the diving response and decrease heart rate. Patients can repeat this up to 3 times. Alternatively, cold compresses or gel eye masks can be used.

I – Intense exercise

Aerobic exercise for 10-20 minutes. This can include running, jumping jacks, dancing to loud music in a way that feels intense. The parasympathetic nervous system (PNS) is activated for approximately 20 minutes after cessation of intense exercise.

P – Paced breathing

Decreasing rate of breathing, with each inhalation/exhalation cycle lasting 10-12 seconds and the exhale being longer than the inhale also activates the PNS.

P – Progressive muscle relaxation (PMR)

Sequentially tensing and relaxing muscles from head to toes. Having at least 5-10 minutes to perform this exercise is preferred.² Children’s Hospital of Philadelphia offerssample PMR recordings.

Body scans can also be helpful. This practice differs from PMR in that it is a mindfulness practice noting body sensations without trying to change them. The University of Vermont offers some sample exercises.³

These skills were described to Emily. She noted that dunking her face in cold water was effective and it was reassuring knowing she had a tool to help her anxiety. She started to push herself to go outside to exercise. We additionally incorporated other distraction techniques such as identifying items from colors of the rainbow that were around her. She appreciated that she could even do this discreetly while at school. At times she had to do a couple of rounds, but this could help stop her repetitive thoughts so she could use other skills.

Helping patients identify skills that can help in the moment can help them feel supported and gain traction in other areas.
