Infants exposed to SARS-CoV-2 in utero are at increased risk for neurodevelopmental disorders in the first year of life, new research suggests.

But whether it is exposure to the pandemic or maternal exposure to the virus itself that may harm early childhood neurodevelopment is unclear, caution investigators, led by Roy Perlis, MD, MSc, with Massachusetts General Hospital, Boston.

“In this analysis of 222 offspring of mothers infected with SARS-CoV-2, compared with the offspring of 7,550 mothers in the control group (not infected) delivered during the same period, we observed neurodevelopmental diagnoses to be significantly more common among exposed offspring, particularly those exposed to third-trimester maternal infection,” they write.

The study was published online in JAMA Network Open.
 

Speech and language disorders

The study included 7,772 mostly singleton live births across six hospitals in Massachusetts between March and September 2020, including 222 (2.9%) births to mothers with SARS-CoV-2 infection confirmed by polymerase chain reaction testing during pregnancy.

In all, 14 of 222 children born to SARS-CoV-2–infected mothers (6.3%) were diagnosed with a neurodevelopmental disorder in the first year of life versus 227 of 7,550 unexposed offspring (3%) (unadjusted odds ratio, 2.17; 95% confidence interval, 1.24-3.79; P = .006).

In models adjusted for preterm delivery, as well as race, ethnicity, insurance status, child sex, and maternal age, COVID-exposed offspring were significantly more likely to receive a neurodevelopmental diagnosis in the first year of life (adjusted OR, 1.86; 95% CI, 1.03-3.36; P = .04).

The magnitude of the association with neurodevelopmental disorders was greater with third-trimester SARS-CoV-2 infection (aOR, 2.34; 95% CI, 1.23-4.44; P = .01).

The majority of these diagnoses reflected developmental disorders of motor function or speech and language.

The researchers noted that the finding of an association between prenatal SARS-CoV-2 exposure and neurodevelopmental diagnoses at 12 months is in line with a “large body of literature” linking maternal viral infection and maternal immune activation with offspring neurodevelopmental disorders later in life.

They cautioned, however, that whether a definitive connection exists between prenatal SARS-CoV-2 exposure and adverse neurodevelopment in offspring is not yet known, in part because children born to women infected in the first wave of the pandemic haven’t reached their second birthday – a time when neurodevelopment disorders such as autism are typically diagnosed.

There is also the risk for ascertainment bias arising from greater concern for offspring of infected mothers who were ill during pregnancy. These parents may be more inclined to seek evaluation, and clinicians may be more inclined to diagnose or refer for evaluation, the researchers noted.

Nonetheless, as reported by this news organization, the study results support those of research released at the European Psychiatric Association 2022 Congress; those results also showed an association between maternal SARS-CoV-2 infection and impaired neurodevelopment in 6-week-old infants.

In an accompanying commentary, Torri D. Metz, MD, MS, with University of Utah Health, Salt Lake City, said the preliminary findings of Dr. Perlis and colleagues are “critically important, yet many questions remain.”

“Essentially all of what we know now about the effects of in utero exposure to maternal SARS-CoV-2 infection is from children who were exposed to the early and Alpha variants of SARS-CoV-2, as those are the only children now old enough to undergo rigorous neurodevelopmental assessments,” Dr. Metz pointed out.

Ultimately, Dr. Metz said it’s not surprising that the pandemic and in utero exposure to maternal SARS-CoV-2 infection may adversely affect neurodevelopmental outcomes in young children.

Yet, as a retrospective cohort study, the study can only demonstrate associations, not causality.

“This type of work is intended to be hypothesis generating, and that goal has been accomplished as these preliminary findings generate numerous additional research questions to explore,” Dr. Metz wrote.

Among them: Are there genetic predispositions to adverse outcomes? Will we observe differential effects by SARS-CoV-2 variant, by severity of infection, and by trimester of infection? Is it the virus itself or all of the societal changes that occurred during this period, including differences in how those changes were experienced among those with and without SARS-CoV-2?

“Perhaps the most important question is how do we intervene to help mitigate the adverse effects of the pandemic on young children,” Dr. Metz noted.

“Prospective studies to validate these findings, tease out some of the nuance, and identify those at highest risk will help health care practitioners appropriately dedicate resources to improve outcomes as we follow the life course of this generation of children born during the COVID-19 pandemic,” she added.

The study was supported by the National Institute of Mental Health and the National Institute of Child Health and Human Development. Dr. Perlis is an associate editor for JAMA Network Open but was not involved in the editorial review or decision for the study. Dr. Metz reported receiving personal fees and grants from Pfizer and grants from GestVision.

Extended-release methylphenidate (Concerta) had no effect on learning academic material taught in a small group of children with attention-deficit/hyperactivity disorder (ADHD), a controlled crossover study found.

As in previous studies, however, the stimulant did improve seat work productivity and classroom behavior, but these benefits did not translate into better learning of individual academic learning units, according to William E. Pelham Jr., PhD, of the department of psychology at Florida International University in Miami, and colleagues.

The results were published online in the Journal of Consulting and Clinical Psychology.

The authors said the finding raises questions about how stimulant medication leads to improved academic achievement over time. “This is important given that many parents and pediatricians believe that medication will improve academic achievement; parents are more likely to pursue medication (vs. other treatment options) when they identify academic achievement as a primary goal for treatment. The current findings suggest this emphasis may be misguided,” they wrote.

In their view, efforts to improve learning in children with ADHD should focus on delivering effective academic instruction and support such as individualized educational plans rather than stimulant therapy.
 

The study

The study cohort consisted of 173 children aged 7-12 (77% male, 86% Hispanic) who met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria for ADHD and were participating in a therapeutic summer camp classroom.

The experimental design was a triple-masked, within-subject, AB/BA crossover trial. Children completed two consecutive phases of daily, 25-minute instruction in both subject-area content (science and social studies) and vocabulary. Each phase was a standard instructional unit lasting for 3 weeks and lessons were given by credentialed teachers via small-group, evidence-based instruction.

Each child was randomized to receive daily osmotic-release oral system methylphenidate (OROS-MPH) during either the first or second instructional phase and to receive placebo during the other.

Seat work referred to the amount of work a pupil completed in a fixed duration of independent work time, and classroom behavior referred to the frequency of violating classroom rules. Learning was measured by tests, and multilevel models were fit separately to the subject and vocabulary test scores, with four observations per child: pretest and posttest in the two academic subject areas.

The results showed that medication had large, salutary, statistically significant effects on children’s academic seat work productivity and classroom behavior on every single day of the instructional period.

Pupils completed 37% more arithmetic problems per minute when taking OROS-MPH and committed 53% fewer rule violations per hour. In terms of learning the material taught during instruction, however, tests showed that children learned the same amount of subject-area and vocabulary content whether they were taking OROS-MPH or placebo during the instructional period.

Consistent with previous studies, medication slightly helped to improve test scores when taken on the day of a test, but not enough to boost most children’s grades. For example, medication helped children increase on average 1.7 percentage points out of 100 on science and social studies tests.

“This finding has relevance for parents deciding whether to medicate their child for occasions such as a psychoeducational evaluation or high-stakes academic testing – while the effect size was small, findings suggest being medicated would improve scores,” the investigators wrote.

Sharing his perspective on the study but not involved in it, Herschel R. Lessin, MD, a pediatrician at The Children’s Medical Group in Poughkeepsie, N.Y., and coauthor of the American Academy of Pediatrics (AAP) guidelines on ADHD, said, “If you ignore the sensationalized headlines, this study is an interesting but preliminary first step, and justifies further research on the topic. It also has several potential defects, which the authors in fact address in the supplements.” The cohort size was small, for example, the doses of medication were very low, and the study took place in a controlled therapeutic setting – not the everyday classroom.

“Stimulant medications are targeting these core behavioral symptoms of ADHD ... but the goal of treatment is more than just the reduction of symptoms; it is to improve a child’s overall functioning so that they succeed at what is expected of them and avoid developing even more impairments,” Dr. Harris said, adding that symptom improvement can sometimes allow a child to learn better in the classroom and achieve more academically.

Children with ADHD may have diagnosed or undiagnosed comorbid learning disabilities, with one 2013 study suggesting a rate of 31%-45%.

With such learning disabilities being distinct from core behavioral symptoms, stimulant medications would not be expected to address a child’s learning disability. “In fact, best practice is for a child with ADHD who is not responding to stimulant medication (doctors might refer to this as complex ADHD) to undergo full individual evaluations either through the school system or an outside psychological assessment to assess for potential learning disabilities or other comorbid developmental/learning or psychiatric diagnosis,” Dr. Harris said.

Rather than changing prescribing patterns, she continued, pediatricians could consider advising parents to request learning evaluations through the school system if the child continues to struggle academically with no change in learning outcomes despite improvement in some behavioral outcomes.

As a reference, Dr. Harris recommended the Society for Developmental and Behavioral Pediatrics guidelines for complex ADHD.

Electroconvulsive therapy (ECT) may lower mortality for patients with treatment-resistant major depressive disorder (MDD), new research suggests.

In an analysis of data from a large database of inpatients across the United States, use of ECT for those with resistant MDD was associated with significantly lower in-hospital mortality compared with those who did not receive ECT.

This held true even after the researchers controlled for demographics and loss of function due to comorbid medical conditions.

“I think the risks of ECT are far less than the benefits in this population,” coinvestigator Nagy A. Youssef, MD, PhD, professor of psychiatry and director of clinical research, The Ohio State University, Columbus, told this news organization.

“My hope is that providers will not be afraid to refer appropriate cases for ECT. If meds and other therapeutics are not working, you should start discussing ECT as a second or third line,” he said.

The findings were presented at the American Society of Clinical Psychopharmacology annual meeting.
 

Lower mortality

Dr. Youssef, a brain stimulation researcher who uses ECT in his clinical practice, said that in his experience, it is a highly effective therapy for resistant depression.

“I see great responses in patients who have tried everything else. Most of the time, it works very well, and results are very rewarding.”

For the study, the investigators used a large, national insurance claims database that included 949,394 adult inpatients with MDD across the United States from 2012 to 2014. The cohort represented over 4,000 hospitals across the country.

The investigators used logistic regression to determine the odds ratio for in-hospital all-cause mortality for the 25,535 MDD patients who were treated with ECT in comparison with 923,859 patients with MDD who were not treated with ECT.

Results showed that ECT use was significantly higher among older patients (mean age, 56.9 years), women (64%), and White patients (86.9%). In addition, patients in the ECT group were physically sicker than were their peers in the non-ECT group.

A higher proportion of patients in the ECT group in comparison with the non-ECT group had experienced major loss of physical function (37% vs. 5%, respectively) and extreme loss of physical function (63% vs. 0.2%).

“By loss of function, I mean the degree of impairment caused by medical disease,” said Dr. Youssef.

He added that patients with MDD are more likely to care less for their health and do things that are not good for their well-being, such as drinking alcohol or using drugs, and are less likely to adhere to prescribed medication regimens or seek medical attention for physical illness.

“Also, there is probably a biological component where depression, by dysregulation of the hypothalamus and pituitary regions of the brain, can increase the likelihood of physical illness or disease,” Dr. Youssef said.

After adjusting for demographics and extreme loss of function because of medical conditions, the investigators found that in-hospital mortality was significantly lower in the ECT group (odds ratio [OR], 0.05; 95% confidence interval [CI], 0.02-0.11; P < .001).

In-hospital mortality was numerically but not statistically significantly lower in the ECT group (OR, 0.7; 95% CI, 0.41-1.50; P < .47) when adjusted for demographics and major loss of function.

“While this was not statistically significant with marked loss of function, it is clinically important and meaningful. With extreme loss of function, the decrease in mortality was statistically significant,” Dr. Youssef noted.

A lifesaving treatment

Commenting on the study, Jair C. Soares, MD, PhD, professor and chair, Pat Rutherford Chair in Psychiatry, UT Houston Medical School, Texas, said, “These are interesting results in a very large national sample suggesting some potential benefits of ECT.

“For the most severely ill patients with major depression who do not respond to currently available medications, ECT is still the most efficacious treatment and indeed a lifesaving treatment modality for many patients,” said Dr. Soares, who was not part of the study.

He noted that ECT is not right for everyone, but “as administered these days, with careful patient selection, it is indeed a safe treatment that can save many lives,” Dr. Soares said.

Electroconvulsive therapy (ECT) may lower mortality for patients with treatment-resistant major depressive disorder (MDD), new research suggests.

In an analysis of data from a large database of inpatients across the United States, use of ECT for those with resistant MDD was associated with significantly lower in-hospital mortality compared with those who did not receive ECT.

This held true even after the researchers controlled for demographics and loss of function due to comorbid medical conditions.

“I think the risks of ECT are far less than the benefits in this population,” coinvestigator Nagy A. Youssef, MD, PhD, professor of psychiatry and director of clinical research, The Ohio State University, Columbus, told this news organization.

“My hope is that providers will not be afraid to refer appropriate cases for ECT. If meds and other therapeutics are not working, you should start discussing ECT as a second or third line,” he said.

The findings were presented at the American Society of Clinical Psychopharmacology annual meeting.
 

Lower mortality

Dr. Youssef, a brain stimulation researcher who uses ECT in his clinical practice, said that in his experience, it is a highly effective therapy for resistant depression.

“I see great responses in patients who have tried everything else. Most of the time, it works very well, and results are very rewarding.”

For the study, the investigators used a large, national insurance claims database that included 949,394 adult inpatients with MDD across the United States from 2012 to 2014. The cohort represented over 4,000 hospitals across the country.

The investigators used logistic regression to determine the odds ratio for in-hospital all-cause mortality for the 25,535 MDD patients who were treated with ECT in comparison with 923,859 patients with MDD who were not treated with ECT.

Results showed that ECT use was significantly higher among older patients (mean age, 56.9 years), women (64%), and White patients (86.9%). In addition, patients in the ECT group were physically sicker than were their peers in the non-ECT group.

A higher proportion of patients in the ECT group in comparison with the non-ECT group had experienced major loss of physical function (37% vs. 5%, respectively) and extreme loss of physical function (63% vs. 0.2%).

“By loss of function, I mean the degree of impairment caused by medical disease,” said Dr. Youssef.

He added that patients with MDD are more likely to care less for their health and do things that are not good for their well-being, such as drinking alcohol or using drugs, and are less likely to adhere to prescribed medication regimens or seek medical attention for physical illness.

“Also, there is probably a biological component where depression, by dysregulation of the hypothalamus and pituitary regions of the brain, can increase the likelihood of physical illness or disease,” Dr. Youssef said.

After adjusting for demographics and extreme loss of function because of medical conditions, the investigators found that in-hospital mortality was significantly lower in the ECT group (odds ratio [OR], 0.05; 95% confidence interval [CI], 0.02-0.11; P < .001).

In-hospital mortality was numerically but not statistically significantly lower in the ECT group (OR, 0.7; 95% CI, 0.41-1.50; P < .47) when adjusted for demographics and major loss of function.

“While this was not statistically significant with marked loss of function, it is clinically important and meaningful. With extreme loss of function, the decrease in mortality was statistically significant,” Dr. Youssef noted.

Designations of extreme and major loss of function were derived from ICD codes.

“This is a complex grading system that takes into account how sick the patient is and includes medical disease severity and comorbidities assessed by the clinician,” he said.

Herpes zoster does not appear to increase dementia risk – on the contrary, the viral infection may offer some protection, a large population-based study suggests.

“We were surprised by these results [and] the reasons for the decreased risk are unclear,” study author Sigrun Alba Johannesdottir Schmidt, MD, PhD, with Aarhus (Denmark) University Hospital, said in a news release.

The study was published online in Neurology.
 

Conflicting findings

Herpes zoster (HZ) is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus (VZV). Previous population-based studies have reported both decreased and increased risks of dementia after having HZ.

It’s thought that HZ may contribute to the development of dementia through neuroinflammation, cerebral vasculopathy, or direct neural damage, but epidemiologic evidence is limited.

To investigate further, Dr. Schmidt and colleagues used Danish medical registries to identify 247,305 people who had visited a hospital for HZ or were prescribed antiviral medication for HZ over a 20-year period and matched them to 1,235,890 people who did not have HZ. For both cohorts, the median age was 64 years, and 61% were women.

Dementia was diagnosed in 9.7% of zoster patients and 10.3% of matched control persons during up to 21 years of follow-up.

Contrary to the researchers’ expectation, HZ was associated with a small (7%) decreased relative risk of all-cause dementia during follow-up (hazard ratio, 0.93; 95% confidence interval, 0.90-0.95).

There was no increased long-term risk of dementia in subgroup analyses, except possibly among those with HZ that involved the central nervous system (HR, 1.94; 95% CI, 0.78-4.80), which has been shown before.

However, the population attributable fraction of dementia caused by this rare complication is low (< 1%), suggesting that universal vaccination against VZV in the elderly has limited potential to reduce dementia risk, the investigators noted.

Nonetheless, Dr. Schmidt said shingles vaccination should be encouraged in older people because it can prevent complications from the disease.

The research team admitted that the slightly decreased long-term risk of dementia, including Alzheimer’s disease, was “unexpected.” The reasons for this decreased risk are unclear, they say, and could be explained by missed diagnoses of shingles in people with undiagnosed dementia.

They were not able to examine whether antiviral treatment modifies the association between HZ and dementia and said that this topic merits further research.

The study was supported by the Edel and Wilhelm Daubenmerkls Charitable Foundation. The authors disclosed no relevant financial relationships.

Migraine headaches pose a challenge for many patients and their physicians, so new, effective approaches are always welcome. Sometimes new treatments come as total surprises. For example, who would have guessed that timolol eyedrops could be effective for acute migraine?¹ Granted, the results (discussed in this issue's PURLs) are from a single randomized trial, but they look very promising.

This is not the only new and innovative treatment for migraine. Everyone knows about the heavily marketed calcium gene-related peptide antagonists, which include monoclonal antibodies and the so-called “gepants.” The monoclonal antibodies and atogepant are approved for migraine prevention, and they do a decent job (although at a high price). In randomized trials, these agents reduced migraine days per month by an average of about 1.5 to 2.5 days compared to placebo.^2-5

Who would have guessed that timolol eyedrops could be effective for acute migraine?

Ubrogepant and rimegepant are approved for acute migraine treatment. In clinical trials, about 20% of patients taking ubrogepant or rimegepant were pain free at 2 hours post dose, compared to 12% to 14% taking placebo.^6,7 Unfortunately, that means 80% of patients still have some pain at 2 hours. By comparison, zolmitriptan performs a bit better, with 34% of patients pain free at 2 hours.⁸ However, for those who can’t tolerate zolmitriptan, these newer options provide an alternative.

We also now have nonpharmacologic options. The caloric vestibular stimulation device is essentially a headset with ear probes that change temperature, alternating warm and cold. In a randomized controlled trial, it reduced monthly migraine days by 1.1 compared to placebo, from a baseline of 7.7 to 3.9 days.⁹ It can also be used to treat acute migraine. There is also a vagus nerve–stimulating device that reduced migraine headache severity by 20% on average in 32.2% of patients in 30 minutes. Sham treatment was as effective for 18.5% of patients, giving a number needed to treat of 6 compared to sham.¹⁰

And finally, there are complementary and alternative medicine options. Two recent randomized trials demonstrated that ≥ 2000 IU/d of vitamin D reduced monthly migraine days an average of 2 days, which is comparable to the effectiveness of the calcium gene-related peptide antagonists at a fraction of the cost.^11,12 In another randomized trial, intranasal 1.5% peppermint oil was as effective as topical 4% lidocaine in providing substantial pain relief for acute migraine; about 42% of patients achieved significant relief with either treatment.¹³

While we may not have a perfect treatment for our patients with migraine headache, we certainly have many options to choose from.

CHARLOTTE, N.C. – Overnight sleep electroencephalography (EEG) contains an abundance of brain wave data that could be mined to identify an individual’s risk for a host of health outcomes, including dementia, cognitive impairment, and cardiovascular events, a researcher reported at the annual meeting of the Associated Professional Sleep Societies. “Sleep EEGs contain decodable information about the risk of unfavorable outcomes,” said Haoqi Sun, PhD, an instructor of neurology at Massachusetts General Hospital, Boston, and lead study author. “The results suggest that it’s feasible to use sleep to identify people with high risk of unfavorable outcomes and it strengthens the concept of sleep as a window into brain and general health.”

The researchers performed a quantitative analysis of sleep data collected on 8,673 adults who had diagnostic sleep studies that included polysomnography (PSG). The analysis used ICD codes to consider these 11 health outcomes: dementia, mild cognitive impairment (MCI) or dementia, ischemic stroke, intracranial hemorrhage, atrial fibrillation, myocardial infarction, type 2 diabetes, hypertension, bipolar disorder, depression, and mortality.

Then, Dr. Sun explained, they extracted 86 spectral and time-domain features of REM and non-REM sleep from sleep EEG recordings, and analyzed that data by adjusting for eight covariates including age, sex, body mass index, and use of benzodiazepines, antidepressants, sedatives, antiseizure drugs, and stimulants.

Participants were partitioned into three sleep-quality groups: poor, average, and good. The outcome-wise mean prediction difference in 10-year cumulative incidence was 2.3% for the poor sleep group, 0.5% for the average sleep group, and 1.3% for the good sleep group.

The outcomes with the three greatest poor to average risk ratios were dementia (6.2; 95% confidence interval, 4.5-9.3), mortality (5.7; 95% CI, 5-7.5) and MCI or dementia (4; 95% CI, 3.2-4.9).
 

Ready for the clinic?

In an interview, Dr. Sun said the results demonstrated the potential of using EEG brain wave data to predict health outcomes on an individual basis, although he acknowledged that most of the 86 sleep features the researchers used are not readily available in the clinic.

He noted the spectral features used in the study can be captured through software compatible with PSG. “From there you can identify the various bands, the different frequency ranges, and then you can easily see within this range whether a person has a higher power or lower power,” he said. However, the spindle and slow-oscillation features that researchers used in the study are beyond the reach of most clinics.
 

Next steps

This research is in its early stage, Dr. Sun said, but at some point the data collected from sleep studies could be paired with machine learning to make the model workable for evaluating individual patients. “Our goal is to first make this individualized,” he said. “We want to minimize the noise in the recording and minimize the night-to-night variability in the findings. There is some clinical-informed approach and there is also some algorithm-informed approach where you can minimize the variation over time.”

The model also has the potential to predict outcomes, particularly with chronic diseases such as diabetes and dementia, well before a diagnosis is made, he said.
 

‘Fascinating’ and ‘provocative’

Donald Bliwise, PhD, professor of neurology at Emory Sleep Center in Atlanta, said the study was “fascinating; it’s provocative; it’s exciting and interesting,” but added, “Sleep is vital for health. That’s abundantly clear in a study like that, but trying to push it a little bit further with all of these 86 measurements of the EEG, I think it becomes complicated.”

The study methodology, particularly the use of cumulative incidence of various diseases, was laudable, he said, and the use of simpler EEG-measured sleep features, such as alpha band power, “make intuitive sense.”

But it’s less clear on how the more sophisticated features the study model used – for example, kurtosis of theta frequency or coupling between spindle and slow oscillation – rank on sleep quality, he said, adding that the researchers have most likely done that but couldn’t add that into the format of the presentation.

“Kurtosis of the theta frequency band we don’t get on everyone in the sleep lab,” Dr. Bliwise said. “We might be able to, but I don’t know how to quite plug that into a turnkey model.”

The clinical components of the study were conducted by M. Brandon Westover, MD, PhD, at Massachusetts General Hospital, and Robert J. Thomas, MD, at Beth Israel Deaconess Medical Center, both in Boston. The study received support from the American Academy of Sleep Medicine Foundation. Dr. Sun has no relevant disclosures.

But it’s less clear on how the more sophisticated features the study model used – for example, kurtosis of theta frequency or coupling between spindle and slow oscillation – rank on sleep quality, he said, adding that the researchers have most likely done that but couldn’t add that into the format of the presentation.

“Kurtosis of the theta frequency band we don’t get on everyone in the sleep lab,” Dr. Bliwise said. “We might be able to, but I don’t know how to quite plug that into a turnkey model.”

The clinical components of the study were conducted by M. Brandon Westover, MD, PhD, at Massachusetts General Hospital, and Robert J. Thomas, MD, at Beth Israel Deaconess Medical Center, both in Boston. The study received support from the American Academy of Sleep Medicine Foundation. Dr. Sun has no relevant disclosures.

CHARLOTTE, N.C. – Overnight sleep electroencephalography (EEG) contains an abundance of brain wave data that could be mined to identify an individual’s risk for a host of health outcomes, including dementia, cognitive impairment, and cardiovascular events, a researcher reported at the annual meeting of the Associated Professional Sleep Societies. “Sleep EEGs contain decodable information about the risk of unfavorable outcomes,” said Haoqi Sun, PhD, an instructor of neurology at Massachusetts General Hospital, Boston, and lead study author. “The results suggest that it’s feasible to use sleep to identify people with high risk of unfavorable outcomes and it strengthens the concept of sleep as a window into brain and general health.”

The researchers performed a quantitative analysis of sleep data collected on 8,673 adults who had diagnostic sleep studies that included polysomnography (PSG). The analysis used ICD codes to consider these 11 health outcomes: dementia, mild cognitive impairment (MCI) or dementia, ischemic stroke, intracranial hemorrhage, atrial fibrillation, myocardial infarction, type 2 diabetes, hypertension, bipolar disorder, depression, and mortality.

Then, Dr. Sun explained, they extracted 86 spectral and time-domain features of REM and non-REM sleep from sleep EEG recordings, and analyzed that data by adjusting for eight covariates including age, sex, body mass index, and use of benzodiazepines, antidepressants, sedatives, antiseizure drugs, and stimulants.

Participants were partitioned into three sleep-quality groups: poor, average, and good. The outcome-wise mean prediction difference in 10-year cumulative incidence was 2.3% for the poor sleep group, 0.5% for the average sleep group, and 1.3% for the good sleep group.

The outcomes with the three greatest poor to average risk ratios were dementia (6.2; 95% confidence interval, 4.5-9.3), mortality (5.7; 95% CI, 5-7.5) and MCI or dementia (4; 95% CI, 3.2-4.9).
 

Ready for the clinic?

In an interview, Dr. Sun said the results demonstrated the potential of using EEG brain wave data to predict health outcomes on an individual basis, although he acknowledged that most of the 86 sleep features the researchers used are not readily available in the clinic.

He noted the spectral features used in the study can be captured through software compatible with PSG. “From there you can identify the various bands, the different frequency ranges, and then you can easily see within this range whether a person has a higher power or lower power,” he said. However, the spindle and slow-oscillation features that researchers used in the study are beyond the reach of most clinics.
 

Next steps

This research is in its early stage, Dr. Sun said, but at some point the data collected from sleep studies could be paired with machine learning to make the model workable for evaluating individual patients. “Our goal is to first make this individualized,” he said. “We want to minimize the noise in the recording and minimize the night-to-night variability in the findings. There is some clinical-informed approach and there is also some algorithm-informed approach where you can minimize the variation over time.”

The model also has the potential to predict outcomes, particularly with chronic diseases such as diabetes and dementia, well before a diagnosis is made, he said.
 

‘Fascinating’ and ‘provocative’

Donald Bliwise, PhD, professor of neurology at Emory Sleep Center in Atlanta, said the study was “fascinating; it’s provocative; it’s exciting and interesting,” but added, “Sleep is vital for health. That’s abundantly clear in a study like that, but trying to push it a little bit further with all of these 86 measurements of the EEG, I think it becomes complicated.”

The study methodology, particularly the use of cumulative incidence of various diseases, was laudable, he said, and the use of simpler EEG-measured sleep features, such as alpha band power, “make intuitive sense.”

Opioid use in the elderly is associated with an almost 40% increased risk of dementia in new findings that suggest exposure to these drugs may be another modifiable risk factor for dementia.

“Clinicians and others may want to consider that opioid exposure in those aged 75-80 increases dementia risk, and to balance the potential benefits of opioid use in old age with adverse side effects,” said Stephen Z. Levine, PhD, professor, department of community mental health, University of Haifa (Israel).

The study was published online in the American Journal of Geriatric Psychiatry.
 

Widespread use

Evidence points to a relatively high rate of opioid prescriptions among older adults. A Morbidity and Mortality Weekly Report noted 19.2% of the U.S. adult population filled an opioid prescription in 2018, with the rate in those over 65 double that of adults aged 20-24 years (25% vs. 11.2%).

Disorders and illnesses for which opioids might be prescribed, including cancer and some pain conditions, “are far more prevalent in old age than at a younger age,” said Dr. Levine.

This high rate of opioid use underscores the need to consider the risks of opioid use in old age, said Dr. Levine. “Unfortunately, studies of the association between opioid use and dementia risk in old age are few, and their results are inconsistent.”

The study included 91,307 Israeli citizens aged 60 and over without dementia who were enrolled in the Meuhedet Healthcare Services, a nonprofit health maintenance organization (HMO) serving 14% of the country’s population. Meuhedet has maintained an up-to-date dementia registry since 2002.

The average age of the study sample was 68.29 years at the start of the study (in 2012).

In Israel, opioids are prescribed for a 30-day period. In this study, opioid exposure was defined as opioid medication fills covering 60 days (or two prescriptions) within a 120-day interval.

The primary outcome was incident dementia during follow-up from Jan. 1, 2013 to Oct. 30, 2017. The analysis controlled for a number of factors, including age, sex, smoking status, health conditions such as arthritis, depression, diabetes, osteoporosis, cognitive decline, vitamin deficiencies, cancer, cardiovascular conditions, and hospitalizations for falls.

Researchers also accounted for the competing risk of mortality.

During the study, 3.1% of subjects were exposed to opioids at a mean age of 73.94 years, and 5.8% of subjects developed dementia at an average age of 78.07 years.
 

Increased dementia risk

The risk of incident dementia was significantly increased in those exposed to opioids versus unexposed individuals in the 75- to 80-year age group (adjusted hazard ratio, 1.39; 95% confidence interval, 1.01-1.92; z statistic = 2.02; P < .05).

The authors noted the effect size for opioid exposure in this elderly age group is like other potentially modifiable risk factors for dementia, including body mass index and smoking.

The current study could not determine the biological explanation for the increased dementia risk among older opioid users. “Causal notions are challenging in observational studies and should be viewed with caution,” Dr. Levine noted.

However, a plausible mechanism highlighted in the literature is that opioids promote apoptosis of microglia and neurons that contribute to neurodegenerative diseases, he said.

The study included 14 sensitivity analyses, including those that looked at females, subjects older than 70, smokers, and groups with and without comorbid health conditions. The only sensitivity analysis that didn’t have similar findings to the primary analysis looked at dementia risk restricted to subjects without a vitamin deficiency.

“It’s reassuring that 13 or 14 sensitivity analyses found a significant association between opioid exposure and dementia risk,” said Dr. Levine.

Some prior studies did not show an association between opioid exposure and dementia risk. One possible reason for the discrepancy with the current findings is that the previous research didn’t account for age-specific opioid use effects, or the competing risk of mortality, said Dr. Levine.

Clinicians have a number of potential alternatives to opioids to treat various conditions including acetaminophen, non-steroidal anti-inflammatory drugs, amine reuptake inhibitors (ARIs), membrane stabilizers, muscle relaxants, topical capsaicin, botulinum toxin, cannabinoids, and steroids.

A limitation of the study was that it didn’t adjust for all possible comorbid health conditions, including vascular conditions, or for use of benzodiazepines, and surgical procedures.

In addition, since up to 50% of dementia cases are undetected, it’s possible some in the unexposed opioid group may actually have undiagnosed dementia, thereby reducing the effect sizes in the results.

Reverse causality is also a possibility as the neuropathological process associated with dementia could have started prior to opioid exposure. In addition, the results are limited to prolonged opioid exposure.
 

Interpret with caution

Commenting on the study, David Knopman, MD, a neurologist at Mayo Clinic in Rochester, Minn., whose research involves late-life cognitive disorders, was skeptical.

“On the face of it, the fact that an association was seen only in one narrow age range – 75+ to 80 years – ought to raise serious suspicion about the reliability and validity of the claim that opioid use is a risk factor for dementia, he said.

Although the researchers performed several sensitivity analyses, including accounting for mortality, “pharmacoepidemiological studies are terribly sensitive to residual biases” related to physician and patient choices related to medication use, added Dr. Knopman.

The claim that opioids are a dementia risk “should be viewed with great caution” and should not influence use of opioids where they’re truly indicated, he said.

“It would be a great pity if patients with pain requiring opioids avoid them because of fears about dementia based on the dubious relationship between age and opioid use.”

Dr. Levine and Dr. Knopman report no relevant financial disclosures.

A person’s ‘genetic’ height – the height they are predicted to reach independent of environmental influences – may be an underappreciated risk factor for a wide range of chronic conditions, according to a study published in PLOS Genetics.

Prior studies have investigated height as a risk factor for chronic diseases, such as a higher risk for atrial fibrillation and a reduced risk of cardiovascular disease. It’s been consistently difficult, however, to eliminate the confounding influences of diet, socioeconomics, lifestyle behaviors, and other environmental factors that may interfere with a person’s reaching their expected height based on their genes.

This study, however, was able to better parse those differences by using Mendelian randomization within the comprehensive clinical and genetic dataset of a national health care system biobank. Mendelian randomization uses “genetic instruments for exposures of interest under the assumption that genotype is less susceptible to confounding than measured exposures,” the authors explained. The findings confirmed previously suspected associations between height and a range of cardiovascular and metabolic conditions as well as revealing new associations with several other conditions.
 

Prior associations confirmed, new associations uncovered

The results confirmed that being tall is linked to a higher risk of atrial fibrillation and varicose veins, and a lower risk of coronary heart disease, high blood pressure, and high cholesterol. The study also uncovered new associations between greater height and a higher risk of peripheral neuropathy, which is caused by damage to nerves on the extremities, as well as skin and bone infections, such as leg and foot ulcers.

The meta-analysis “identified five additional traits associated with genetically-predicted height,” wrote Sridharan Raghavan, MD, assistant professor of medicine at the University of Colorado Anschutz Medical Campus, and colleagues. “Two were genitourinary conditions – erectile dysfunction and urinary retention – that can be associated with neuropathy, and a third was a phecode for nonspecific skin disorders that may be related to skin infections – consistent with the race/ethnicity stratified results.”
 

Removing potential confounders

F. Perry Wilson, MD, associate professor of medicine at Yale University, New Haven, Conn., who was not involved in the study, said the findings were not particularly surprising overall, but it’s striking that the researchers had ”such a large cohort with such detailed electronic health records allowing for the comparison of genetic height with a variety of clinical outcomes.” He also noted the study’s strength in using Mendelian randomization so that the exposure is the predicted genetic height instead of a person’s measured height.

“This is key, since lots of things affect actual height – nutrition is an important one that could certainly be linked to disease as well,” Dr. Wilson said. ”By using genetic height, the authors remove these potential confounders. Since genetic height is “assigned” at birth (or conception), there is little opportunity for confounding. Of course, it is possible that some of the gene variants used to predict genetic height actually do something else, such as make you seek out less nutritious meals, but by and large this is how these types of studies need to be done.”
 

Height may impact over 100 clinical traits

The study relied on data from the U.S. Veteran Affairs Million Veteran Program with 222,300 non-Hispanic White and 58,151 non-Hispanic Black participants. The researchers first estimated the likelihood of participants’ genetic height based on 3,290 genetic variants determined to affect genetic height in a recent European-ancestry genome-wide meta-analysis. Then they compared these estimates with participants’ actual height in the VA medical record, adjusting for age, sex, and other genetic characteristics.

In doing so, the researchers found 345 clinical traits that were associated with the actual measured height in White participants plus another 17 clinical trials linked to actual measured height in Black participants. An overall 127 of these clinical traits were significantly associated with White participants’ genetically predicted height, and two of them were significantly associated with Black participants’ genetically predicted height.

In analyzing all these data together, the researchers were largely able to separate out those associations between genetically predicted height and certain health conditions from those associations between health conditions and a person’s actual measured height. They also determined that including body mass index as a covariate had little impact on the results. The researchers conducted the appropriate statistical correction to ensure the use of so many variables did not result in spurious statistical significance in some associations.

“Using genetic methods applied to the VA Million Veteran Program, we found evidence that adult height may impact over 100 clinical traits, including several conditions associated with poor outcomes and quality of life – peripheral neuropathy, lower extremity ulcers, and chronic venous insufficiency. We conclude that height may be an unrecognized nonmodifiable risk factor for several common conditions in adults.”
 

Height linked with health conditions

Genetically predicted height predicted a reduced risk of hyperlipidemia and hypertension independent of coronary heart disease, the analysis revealed. Genetically predicted height was also linked to an approximately 51% increased risk of atrial fibrillation in participants without coronary heart disease but, paradoxically, only a 39% increased risk in those with coronary heart disease, despite coronary heart disease being a risk factor for atrial fibrillation. Genetically predicted height was also associated with a greater risk of varicose veins in the legs and deep vein thrombosis.

Another novel association uncovered by the analysis was between women’s genetically predicted height and both asthma and nonspecific peripheral nerve disorders. “Whether these associations reflect differences by sex in disease pathophysiology related to height may warrant exploration in a sample with better balance between men and women,” the authors wrote. “In sum, our results suggest that an individual’s height may warrant consideration as a nonmodifiable predictor for several common conditions, particularly those affecting peripheral/distal extremities that are most physically impacted by tall stature.”

A substantial limitation of the study was its homogeneity of participants, who were 92% male with an average height of 176 cm and an average BMI of 30.1. The Black participants tended to be younger, with an average age of 58 compared with 64 years in the White participants, but the groups were otherwise similar in height and weight.* The database included data from Hispanic participants, but the researchers excluded these data because of the small sample size.

The smaller dataset for Black participants was a limitation as well as the fact that the genome-wide association study the researchers relied on came from a European population, which may not be as accurate in people with other ancestry, Dr. Wilson said. The bigger limitation, however, is what the findings’ clinical relevance is.
 

What does it all mean?

“Genetic height is in your genes – there is nothing to be done about it – so it is more of academic interest than clinical interest,” Dr. Wilson said. It’s not even clear whether incorporating a person’s height – actual or genetically predicted, if it could be easily determined for each person – into risk calculators. ”To know whether it would be beneficial to use height (or genetic height) as a risk factor, you’d need to examine each condition of interest, adjusting for all known risk factors, to see if height improved the prediction,” Dr. Wilson said. “I suspect for most conditions, the well-known risk factors would swamp height. For example, high genetic height might truly increase risk for neuropathy. But diabetes might increase the risk so much more that height is not particularly relevant.”

On the other hand, the fact that height in general has any potential influence at all on disease risk may inspire physicians to consider other risk factors in especially tall individuals.

”Physicians may find it interesting that we have some confirmation that height does increase the risk of certain conditions,” Dr. Wilson said. “While this is unlikely to dramatically change practice, they may be a bit more diligent in looking for other relevant risk factors for the diseases found in this study in their very tall patients.”

The research was funded by the U.S. Department of Veteran Affairs, the Boettcher Foundation’s Webb-Waring Biomedical Research Program, the National Institutes of Health, and a Linda Pechenik Montague Investigator award. One study coauthor is a full-time employee of Novartis Institutes of Biomedical Research. The other authors and Dr. Wilson had no disclosures.

An overall 127 of these clinical traits were significantly associated with White participants’ genetically predicted height, and two of them were significantly associated with Black participants’ genetically predicted height.

In analyzing all these data together, the researchers were largely able to separate out those associations between genetically predicted height and certain health conditions from those associations between health conditions and a person’s actual measured height. They also determined that including body mass index as a covariate had little impact on the results. The researchers conducted the appropriate statistical correction to ensure the use of so many variables did not result in spurious statistical significance in some associations.

“Using genetic methods applied to the VA Million Veteran Program, we found evidence that adult height may impact over 100 clinical traits, including several conditions associated with poor outcomes and quality of life – peripheral neuropathy, lower extremity ulcers, and chronic venous insufficiency. We conclude that height may be an unrecognized nonmodifiable risk factor for several common conditions in adults.”
 

Height linked with health conditions

Genetically predicted height predicted a reduced risk of hyperlipidemia and hypertension independent of coronary heart disease, the analysis revealed. Genetically predicted height was also linked to an approximately 51% increased risk of atrial fibrillation in participants without coronary heart disease but, paradoxically, only a 39% increased risk in those with coronary heart disease, despite coronary heart disease being a risk factor for atrial fibrillation. Genetically predicted height was also associated with a greater risk of varicose veins in the legs and deep vein thrombosis.

Another novel association uncovered by the analysis was between women’s genetically predicted height and both asthma and nonspecific peripheral nerve disorders. “Whether these associations reflect differences by sex in disease pathophysiology related to height may warrant exploration in a sample with better balance between men and women,” the authors wrote. “In sum, our results suggest that an individual’s height may warrant consideration as a nonmodifiable predictor for several common conditions, particularly those affecting peripheral/distal extremities that are most physically impacted by tall stature.”

A substantial limitation of the study was its homogeneity of participants, who were 92% male with an average height of 176 cm and an average BMI of 30.1. The Black participants tended to be younger, with an average age of 58 compared with 64 years in the White participants, but the groups were otherwise similar in height and weight.* The database included data from Hispanic participants, but the researchers excluded these data because of the small sample size.

The smaller dataset for Black participants was a limitation as well as the fact that the genome-wide association study the researchers relied on came from a European population, which may not be as accurate in people with other ancestry, Dr. Wilson said. The bigger limitation, however, is what the findings’ clinical relevance is.
 

What does it all mean?

“Genetic height is in your genes – there is nothing to be done about it – so it is more of academic interest than clinical interest,” Dr. Wilson said. It’s not even clear whether incorporating a person’s height – actual or genetically predicted, if it could be easily determined for each person – into risk calculators. ”To know whether it would be beneficial to use height (or genetic height) as a risk factor, you’d need to examine each condition of interest, adjusting for all known risk factors, to see if height improved the prediction,” Dr. Wilson said. “I suspect for most conditions, the well-known risk factors would swamp height. For example, high genetic height might truly increase risk for neuropathy. But diabetes might increase the risk so much more that height is not particularly relevant.”

On the other hand, the fact that height in general has any potential influence at all on disease risk may inspire physicians to consider other risk factors in especially tall individuals.

”Physicians may find it interesting that we have some confirmation that height does increase the risk of certain conditions,” Dr. Wilson said. “While this is unlikely to dramatically change practice, they may be a bit more diligent in looking for other relevant risk factors for the diseases found in this study in their very tall patients.”

The research was funded by the U.S. Department of Veteran Affairs, the Boettcher Foundation’s Webb-Waring Biomedical Research Program, the National Institutes of Health, and a Linda Pechenik Montague Investigator award. One study coauthor is a full-time employee of Novartis Institutes of Biomedical Research. The other authors and Dr. Wilson had no disclosures.

A person’s ‘genetic’ height – the height they are predicted to reach independent of environmental influences – may be an underappreciated risk factor for a wide range of chronic conditions, according to a study published in PLOS Genetics.

Prior studies have investigated height as a risk factor for chronic diseases, such as a higher risk for atrial fibrillation and a reduced risk of cardiovascular disease. It’s been consistently difficult, however, to eliminate the confounding influences of diet, socioeconomics, lifestyle behaviors, and other environmental factors that may interfere with a person’s reaching their expected height based on their genes.

This study, however, was able to better parse those differences by using Mendelian randomization within the comprehensive clinical and genetic dataset of a national health care system biobank. Mendelian randomization uses “genetic instruments for exposures of interest under the assumption that genotype is less susceptible to confounding than measured exposures,” the authors explained. The findings confirmed previously suspected associations between height and a range of cardiovascular and metabolic conditions as well as revealing new associations with several other conditions.
 

Prior associations confirmed, new associations uncovered

The results confirmed that being tall is linked to a higher risk of atrial fibrillation and varicose veins, and a lower risk of coronary heart disease, high blood pressure, and high cholesterol. The study also uncovered new associations between greater height and a higher risk of peripheral neuropathy, which is caused by damage to nerves on the extremities, as well as skin and bone infections, such as leg and foot ulcers.

The meta-analysis “identified five additional traits associated with genetically-predicted height,” wrote Sridharan Raghavan, MD, assistant professor of medicine at the University of Colorado Anschutz Medical Campus, and colleagues. “Two were genitourinary conditions – erectile dysfunction and urinary retention – that can be associated with neuropathy, and a third was a phecode for nonspecific skin disorders that may be related to skin infections – consistent with the race/ethnicity stratified results.”
 

Removing potential confounders

F. Perry Wilson, MD, associate professor of medicine at Yale University, New Haven, Conn., who was not involved in the study, said the findings were not particularly surprising overall, but it’s striking that the researchers had ”such a large cohort with such detailed electronic health records allowing for the comparison of genetic height with a variety of clinical outcomes.” He also noted the study’s strength in using Mendelian randomization so that the exposure is the predicted genetic height instead of a person’s measured height.

“This is key, since lots of things affect actual height – nutrition is an important one that could certainly be linked to disease as well,” Dr. Wilson said. ”By using genetic height, the authors remove these potential confounders. Since genetic height is “assigned” at birth (or conception), there is little opportunity for confounding. Of course, it is possible that some of the gene variants used to predict genetic height actually do something else, such as make you seek out less nutritious meals, but by and large this is how these types of studies need to be done.”
 

Height may impact over 100 clinical traits

The study relied on data from the U.S. Veteran Affairs Million Veteran Program with 222,300 non-Hispanic White and 58,151 non-Hispanic Black participants. The researchers first estimated the likelihood of participants’ genetic height based on 3,290 genetic variants determined to affect genetic height in a recent European-ancestry genome-wide meta-analysis. Then they compared these estimates with participants’ actual height in the VA medical record, adjusting for age, sex, and other genetic characteristics.

In doing so, the researchers found 345 clinical traits that were associated with the actual measured height in White participants plus another 17 clinical trials linked to actual measured height in Black participants. An overall 127 of these clinical traits were significantly associated with White participants’ genetically predicted height, and two of them were significantly associated with Black participants’ genetically predicted height.

In analyzing all these data together, the researchers were largely able to separate out those associations between genetically predicted height and certain health conditions from those associations between health conditions and a person’s actual measured height.

Four common motor abnormalities in schizophrenia patients were associated with at least one poor functional outcome, based on data from 156 individuals.

Approximately half of adults with schizophrenia suffer from motor abnormalities that may impair their ability to work and decrease their quality of life, wrote Niluja Nadesalingam, MD, of the University of Bern, Switzerland, and colleagues. “Although previous reports show strong associations between single movement abnormalities and global as well as social functioning, we still struggle to understand the contribution of various motor domains,” they said.

The impact of these abnormalities on social and global functioning and on functional capacity remains unclear, but the researchers proposed that motor abnormalities would be associated with worse functional outcomes in schizophrenia patients.

In a study published in Comprehensive Psychiatry, the researchers identified patients with diagnosed schizophrenia spectrum disorders who were treated on an inpatient or outpatient basis at a single center. They collected data on five motor abnormalities: parkinsonism, catatonia, dyskinesia, neurological soft signs (NSS), and psychomotor slowing (PS). They assessed functional outcomes using the Global Assessment of Functioning (GAF), the Social and Occupational Functioning Assessment Scale (SOFAS), and the UCSD Performance-Based Skills Assessment (UPSA-B). The average age of the participants was 37.9 years and 88 of the 156 were male. The average duration of illness was 12.5 years.

Overall, patients with catatonia and parkinsonism scored significantly lower on GAF and SOFAS scale compared to those without catatonia and parkinsonism (P < .035 and P < .027, respectively).

No significant differences in functional outcomes appeared between patients with and without dyskinesia.

However, significant negative correlations were identified for parkinsonism and PS with GAF, SOFAS, and UPSA-B (P < .036 for all). “Our study further found that parkinsonism and psychomotor slowing also impair the functional capacity of patients,” which may be influenced by factors including deficits in social interaction and cognitive impairment, the researchers said.

Overall, the study findings demonstrate that motor abnormalities in patients with schizophrenia are strongly associated with poor functional outcomes, and the stronger the motor impairment, the worse the global and social functioning, the researchers said.

As for potential pathways, “motor abnormalities are readily observable signs, allowing laypersons to perceive subjects with schizophrenia as somebody with severe mental illness. Thus, motor abnormalities might lead to stigmatization of patients suffering from schizophrenia,” they wrote in their discussion.

The researchers emphasized the need to explore alternative treatment options that might improve motor abnormalities, such as transcranial magnetic stimulation, given the potential of antipsychotic medications to introduce additional motor abnormalities.

The study findings were limited by several factors including the potential for missed confounding variables, the small number of patients with dyskinesia, and the inability to deduce the course of illness because most of the patients were in psychotic episodes, the researchers noted.

However, the results suggest that specific motor abnormalities are associated with poor global and social functioning, and with reduced functional capacity, in adults with schizophrenia, the researchers said. “Future studies need to test whether amelioration of motor abnormalities may improve community functioning,” they concluded.

The study was supported by the Swiss National Science Foundation, the Bangerter Rhyner Foundation, and the Adrian and Simone Frutiger Foundation. Lead author Dr. Nadesalingam had no financial conflicts to disclose.

Deaf babies and toddlers with developmental delays may benefit significantly from receiving cochlear implants over hearing aids.

A new study, published in the journal Pediatrics, pushes against the notion that children with low nonverbal cognition and adaptive functioning skills won’t improve if given cochlear implants. Some insurers cover hearing aids for children with developmental disorders but not the implants, which can cost between $60,000 and $100,000 per ear.

“We were surprised [by] the large magnitude of the improvements, not only in quality of life, but also in cognition, ability to function in daily living situations, and speech and language,” lead author John S. Oghalai, MD, of the University of Southern California, Los Angeles, told this news organization. “Remember, these are children with substantial developmental delays. Any improvements are incredibly important and meaningful.”

All children with severe hearing loss should be referred for cochlear implant evaluation, “regardless of the presence of other disabilities,” Dr. Oghalai said. “The younger this referral happens, the better the outcomes will be.”

Dr. Oghalai and his colleagues reviewed data from 204 children approximately 1-3 years old with hearing aids receiving treatment in Texas and California. Of these, 138 received a cochlear implant and had normal cognitive skills and social competence (referred to as adaptive behavior). Another 37 received a cochlear implant and also met criteria for early developmental impairment (EDI), defined by measures of nonverbal cognitive scores and adaptive functioning.

A third group of 29 children with EDI continued with hearing aids without a cochlear implant.

The children were evaluated annually for 1-5 years, with the average follow-up of 2 years. At baseline, no significant differences were noted between the children with EDI who received implants and those who did not on cognition, language, auditory skills, or measures of parental or child stress.

Overall, children who received implants scored higher on cognitive and social measures than those who continued using hearing aids.

Compared with children with EDI who received implants, children without EDI who received implants had significantly higher developmental scores by the study’s end (P ≤ .001), whereas children with EDI who did not receive implants had significantly lower scores (P ≤ .04).

Children who received implants, and their parents, also experienced less stress than those who did not receive the devices, according to the researchers.

Dr. Oghalai and colleagues also measured developmental trajectories for each cohort. Children without delays who received implants had the best outcomes, but those with EDI who received implants had better outcomes than those with EDI and hearing aids.
 

Findings ‘overdue’

“This study is overdue,” Howard Francis, MD, chair of the department of head and neck surgery & communication sciences at Duke University, Durham, N.C., told this news organization.

Dr. Francis called the new research “reasonably powered and designed,” and said it “documents benefits in the cognitive, language, and patient-child relationship domains” in children who received cochlear implants “compared to children with similar levels of developmental delay whose hearing loss was treated using hearing aids.”  

However, “larger studies will be needed to account for potential effects of older age at intervention in the hearing aid group,” he said. Socioeconomic effects are a topic for future research as well, Dr. Francis added.

The researchers initially wanted to perform a controlled clinical trial. However, by the time they secured funding, health insurance policy had changed to cover cochlear implants for children without EDI because of demonstrated benefits shown in studies.

They also were unable to determine the reasons for families’ decisions to choose implants or hearing aids and were unable to assess the impact of insurance on the choice of implantation. But they did find that families with insurers who would cover implants often did choose the devices. Children were also followed for an average of 2 years, so long-term outcomes are unknown.  

Despite these limitations, the results support the value of cochlear implantation in children with disabilities and developmental delays, and it should be discussed with parents, the researchers concluded.

“Cochlear implants are just a tool; they do not provide speech and language,” Dr. Oghalai said. “Any child with severe hearing loss requires significant therapy and education via sign language, auditory-verbal therapy, or both. Making the decision about what type of therapy to do is personal, and it depends upon the family and the options that are available to them in their community.”

The study was funded by the National Institutes of Health. The researchers and Dr. Francis have disclosed no relevant financial relationships.
