Aggression is an underappreciated mental health issue, and biological mechanisms might help explain more extreme forms like intermittent explosive disorder (IED), which is characterized by episodes of sudden impulses and inappropriate aggression, violence, or even verbal outbursts. IED can lead to road rage, domestic abuse, in addition to throwing objects and engaging in other destructive behaviors.

Despite those consequences, aggression hasn’t gained the same level of attention as other psychiatric conditions, according to Emil F. Coccaro, MD, who spoke about the topic at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

“People seem to think that aggressive behavior is bad behavior, and therefore people just need an attitude adjustment. So there’s this sort of stigma, and there are no advocacy groups for it. There are no poster children for it. But there’s a whole lot of biology and neuroscience behind it,” said Dr. Coccaro, in an interview. He is a professor and vice chair of research in psychiatry and behavioral health at Ohio State University, Columbus.

IED is also more common than people generally suspect, with an estimated 4% lifetime incidence, according to Dr. Coccaro, who spoke at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.

There is a general view that psychiatric conditions may lead to increased aggression, but there is little evidence of that. “As a general statement, having a psychological [illness] in and of itself does not really increase the risk of being aggressive. What does is being aggressive in general, and substance use disorder. And the thing with [people who have] substance use disorders is that they only get aggressive when they are aggressive to begin with,” said Dr. Coccaro, noting that the strongest case for the relationship surrounds alcohol abuse.

The DSM-5 criteria for IED include: verbal or physical aggression without destruction, at least twice per week, or three or more episodes of assault or physical destruction within a year. The behavior must be out of proportion to the provocation, cause distress or impairment, and not be accountable by other diagnoses. “If they’re blowing up twice a week, for a few months, and usually they’re doing it for a long time, then that’s different than just blowing up very occasionally. Healthy people, nonaggressive people, maybe they blow up once a year, or even less frequently than that,” Dr. Coccaro said.

Functional magnetic resonance imaging and other imaging studies consistently show differences associated with aggression.

“The IEDs really do distinguish themselves from the psychiatric controls. They also have other stuff going on with them; they have a hostile attribution. And they’re kind of irritable at baseline. They’re not walking around irritable all the time, but the people around them may be walking on eggshells,” Dr. Coccaro said.

The results from these sorts of studies aren’t fully conclusive and can’t be used for diagnosis, in part because of a lack of power. “It’s hard to do these MRI studies and lots and lots of subjects, because they’re kind of expensive,” Dr. Coccaro said. “We’re just not there yet.”

Other, less expensive imaging techniques like near-infrared spectroscopy may improve matters. “That might be something down the road that could lead to something (diagnostic). Right now, most imaging studies are being done to really understand mechanisms,” said Dr. Coccaro.

Those mechanistic studies suggest that the culprit for IED may be a combination of too much drive from subcortical structures like the amygdala and insufficient inhibitor function in the frontal part of the brain. The frontal cortex may suffer a loss of gray matter, according to Dr. Coccaro, and there may be insufficient connectivity, which could weaken signals coming from the frontal areas that might otherwise inhibit lower centers of the brain.

Treatment for IED could be aimed at improving that connectivity and signaling. Ketamine and other anesthetic agents like nitrous oxide may increase connectivity to nerve cells by increasing branching at synaptic dendrites.

Selective serotonin reuptake inhibitors have the potential to treat IED, but their utility is limited because they bind to the presynaptic transporter for serotonin, and more aggressive people have fewer of those transporters. “You only get so much bang for your buck,” Dr. Coccaro said.

Cognitive-behavioral therapy that focuses on anger management and relaxation shows promise. “CBT does help people deal with what’s coming at them. So it’s like, ‘oh, I’m getting angry, I better start doing those relaxation (techniques).’ It teaches them to rethink things.”

During the Q&A session following the presentation, Henry A. Nasrallah, MD, who moderated the session, pointed out that misattribution can occur, leading an affected individual to misread someone’s facial expression and react aggressively, which is a problem also seen in psychosis.

“There are studies showing [that if] you show them a series of faces with different affects, many times paranoid patients read a normal facial expression as threatening. So it may be that it’s the same thing with aggression,” said Dr. Nasrallah, who is a professor of psychiatry, neurology, and neuroscience at the University of Cincinnati.

In the midst of the ongoing COVID-19 pandemic, it’s also possible that mask-wearing could improve or worsen such misunderstandings. “There is expression in the eyes that you can see, but you miss a lot,” Dr. Coccaro said.

For now, the effects of masks remain largely unknown. But that will change. “Sooner or later we will have a bunch of papers coming out about how masks have changed a lot of behaviors,” Dr. Nasrallah said.

Dr. Coccaro has consulted for Avanir, Azevan, and Brackett. Dr. Nasrallah has consulted for Acadia, Alkermes, Allergan Janssen, Otsuka, Indivior, IntraCellular, Neurocrine, Sunovion, Teva, and Boehringer-Ingelheim. Dr. Nasrallah has been on a speaker’s bureau for Acadia, Alkermes, Allergan, Janssen, Otsuka, Indivior, Intracellular, Neurocrine, Noven, Sunovion, and Teva.

Patients aged 12 years and older with multiple sclerosis (MS) who are fully immunized against COVID-19 with either the Pfizer-BioNTech or Moderna mRNA vaccine may be eligible to receive an additional dose now, the National Multiple Sclerosis Society has announced.

New guidance, which is “based on available data from studies and expert consensus opinion” by a panel of MS neurologists and experts, was published Aug. 19 on the organization’s website.

The Food and Drug Administration has authorized an additional dose of the coronavirus vaccine for patients who are expected to not have a normal or adequate immune response to the first two doses. Patients with MS who use certain treatments have a reduced or absent antibody response to the vaccine, according to recent data.

“We want people living with MS to be aware of this additional dose and discuss when they need an additional dose or booster dose with their health care provider,” Julie Fiol, RN, MSW, associate vice president of health care access, National MS Society, said in an interview.

Those who may benefit from an additional dose include patients with MS who use sphingosine 1-phosphate receptor modulators, anti-CD20 monoclonal antibodies, or alemtuzumab (Lemtrada), the National MS Society noted. These particular disease modifying therapies (DMTs) have a stronger effect on the immune system than do other treatments.
 

Protecting ‘the most vulnerable’

Sphingosine 1-phosphate receptor modulators include fingolimod (Gilenya), siponimod (Mayzent), ozanimod (Zeposia), and ponesimod (Ponvory).

Anti-CD20 monoclonal antibodies include ocrelizumab (Ocrevus), ofatumumab (Kesimpta), rituximab (Rituxan), and corresponding biosimilars.

Current data do not support an additional dose for immunocompromised patients who received the Johnson & Johnson vaccine. The FDA and the Centers for Disease Control and Prevention are developing recommendations for these patients, and the National MS Society will update its guidance as needed, the organization noted in its statement.

“Like other medical decisions, the decision to get an additional dose is best made in partnership with your health care provider,” said Ms. Fiol. “Talk to your MS health care provider to determine what is best for you.”

MS itself does not compromise the immune system, but some MS therapies alter the immune system and reduce the body’s response to vaccination. Patients with MS who use B cell-depleting therapies have a better antibody response when they receive the vaccine 3 months or more after the last dose of MS therapy, according to the National MS Society.  

Data suggest that patients with MS are not more susceptible to COVID-19 infection, severe illness, or death than are patients without MS. However, certain groups of patients with MS, such as those who receive B cell-depleting treatments, are more susceptible to having a severe case of COVID-19.

That said, “everyone will need a booster at some point. Those who take DMTs that have greater impact on the immune system are the most urgent need now,” the organization noted.

“Vaccination against COVID-19 is critical for public safety and, especially, the safety of the most vulnerable among us,” said Ms. Fiol. “We encourage everyone with MS get vaccinated.”

Adults aged 65 years and older who develop psychotic manifestations are significantly more likely than those without such manifestations to develop prodromal Parkinson’s disease, data from 925 individuals suggest.

“The presence of perceptual abnormalities and/or delusional ideation among community-dwelling elderly individuals is more widespread than considered in the past,” wrote Ioanna Pachi, MD, of National and Kapodistrian University of Athens Medical School and colleagues. However, those psychoses and their potential impact on prodromal Parkinson’s disease (PD) have not been well studied in community-dwelling populations, they noted in the study, published in Parkinsonism and Related Disorders.

In the study, Dr. Pachi and colleagues reviewed data from 914 participants in the Hellenic Longitudinal Investigation of Aging and Diet study (HELIAD), a cross-sectional, population-based cohort study of older adults in Greece. The average age of the participants was 76 years, and 41% were men. Participants had no delusional features at baseline; delusional features were assessed using the Neuropsychiatric Inventory scale and the Columbia University Scale for Psychopathology in Alzheimer’s disease. The researchers calculated the probability of prodromal PD (pPD) for each participant based on the 2019 International Parkinson and Movement Disorders Society research criteria for prodromal PD.

Over a 3-year follow-up period, 20 participants developed psychotic manifestations and were 1.3 times more likely to have pPD, compared with those without psychoses (P = .006). Those with new-onset psychotic features were categorized together as the NPSY group, regardless of symptom severity or frequency; those with no symptoms at either baseline or during follow-up were categorized as unaffected (UPSY). Most of the NPSY participants showed isolated delusional features, although some expressed hallucinations. Most symptoms were mild.

New-onset psychosis was associated with a fivefold increased risk of both subthreshold parkinsonism and depression (adjusted odds ratios, 4.5 and 5.0, respectively) and with a threefold increased risk of constipation (aOR 2.6). Other factors, including nonsmoking, global cognitive deficit, and anxiety were not significantly associated with new-onset psychotic symptoms after adjusting for confounding factors.

Although the mechanism behind the association remains unclear, “the parallel evolution of psychotic features and prodromal PD could be related to the spreading pattern of neuronal damage that occurs in PD,” the researchers wrote.

The study findings were limited by several factors, including the administration of neuropsychiatric questionnaires by nonpsychiatrists, and lack of detailed psychiatric history, including complete information on medication use, the researchers noted. The small size of the NPSY group also prevented evaluation of the potential associations between pPD and different modalities of hallucinations, they said.

However, the results were strengthened by the overall large and population-based sample size, and the comprehensive evaluation of psychotic features, they wrote. More follow-up evaluations in the HELIAD cohort are planned to further explore the underlying mechanism of the association between late-life psychosis and pPD.

“Provided that these results are confirmed in other community cohorts of elderly subjects, psychotic features may be added to the list of manifestations of pPD,” they concluded.

The study was supported in part by grants from the Alzheimer’s Association, ARISTEIA, and the ESPA-EU program Excellence Grant. It was cofunded by the European Social Fund and Greek National resources, the Ministry for Health and Social Solidarity, Greece, and the Greek State Scholarships Foundation. Dr. Pachi had no disclosures.

Most of the NPSY participants showed isolated delusional features, although some expressed hallucinations. Most symptoms were mild.

New-onset psychosis was associated with a fivefold increased risk of both subthreshold parkinsonism and depression (adjusted odds ratios, 4.5 and 5.0, respectively) and with a threefold increased risk of constipation (aOR 2.6). Other factors, including nonsmoking, global cognitive deficit, and anxiety were not significantly associated with new-onset psychotic symptoms after adjusting for confounding factors.

Although the mechanism behind the association remains unclear, “the parallel evolution of psychotic features and prodromal PD could be related to the spreading pattern of neuronal damage that occurs in PD,” the researchers wrote.

The study findings were limited by several factors, including the administration of neuropsychiatric questionnaires by nonpsychiatrists, and lack of detailed psychiatric history, including complete information on medication use, the researchers noted. The small size of the NPSY group also prevented evaluation of the potential associations between pPD and different modalities of hallucinations, they said.

However, the results were strengthened by the overall large and population-based sample size, and the comprehensive evaluation of psychotic features, they wrote. More follow-up evaluations in the HELIAD cohort are planned to further explore the underlying mechanism of the association between late-life psychosis and pPD.

“Provided that these results are confirmed in other community cohorts of elderly subjects, psychotic features may be added to the list of manifestations of pPD,” they concluded.

The study was supported in part by grants from the Alzheimer’s Association, ARISTEIA, and the ESPA-EU program Excellence Grant. It was cofunded by the European Social Fund and Greek National resources, the Ministry for Health and Social Solidarity, Greece, and the Greek State Scholarships Foundation.

Pimavanserin, a novel antipsychotic drug used to manage hallucinations and delusions in Parkinson’s disease, may lead to increased hospitalizations and deaths, according to a new study.

A retrospective cohort study of elderly patients with Parkinson’s disease who were in long-term care facilities found that the use of pimavanserin (Nuplazid) was associated with an increased risk of 30-day hospitalization and mortality for up to a year.

“Given that a previous study showed typical and atypical antipsychotics more than doubled mortality risk in patients with Parkinson’s disease, we aimed to assess the risk of hospitalization and death associated with pimavanserin,” wrote lead author Y. Joseph Hwang, MD, Johns Hopkins University, Baltimore, and colleagues in the paper. “These findings, in a large real-world cohort within long-term care facilities, may help to inform decisions regarding its risk-benefit balance among patients with Parkinson’s disease.”

The findings were published online Aug. 13 in Neurology.

The researchers enrolled 2,186 patients with Parkinson’s disease aged 65 years and older in Medicare-certified long-term care facilities who also had a pimavanserin prescription and 18,212 nonusers of pimavanserin between Nov. 1, 2015, and December 31, 2018. Patients in the pimavanserin group used the drug over the course of the entire study period. Hospitalization and mortality were calculated from the date of pimavanserin prescription. Propensity score–based inverse probability of treatment weighting (IPTW) was used to balance the two groups on 24 baseline characteristics such as age, sex, and comorbidities.

Pimavanserin use was associated with a 24% higher risk of 30-day hospitalization (adjusted hazard ratio, 1.24; 95% confidence interval, 1.06-1.43). However, “the association did not reach statistical significance in a smaller subcohort of propensity score-matched users and nonusers,” Dr. Hwang and colleagues wrote.

Pimavanserin use was also linked to higher mortality at:

• 90 days (aHR, 1.20; 95% CI, 1.02-1.41).
• 180 days (aHR, 1.28; 95% CI, 1.13-1.45).
• 365 days (aHR, 1.56; 95% CI, 1.42-1.72).

No associations were found between pimavanserin use and 90-day hospitalization (aHR, 1.10; 95% CI, 0.99-1.24) nor with 30-day mortality (aHR, 0.76; 95% CI, 0.56-1.03).
 

Important considerations

“This study raises three important points to consider for any practicing neurology provider: 1) how to address and interpret risks associated with pimavanserin use in this patient population 2) utility of pimavanserin 3) interpretation of data showing increased mortality in patients being treated for Parkinson’s disease psychosis,” wrote Farwa Ali, MBBS, of the Mayo Clinic, Rochester, Minn., in an accompanying editorial published in Neurology.

Hallucinations and delusions are highly prevalent in Parkinson’s disease; as many as 60% of patients will develop psychosis over the course of their illness. Pimavanserin is a selective serotonin inverse agonist which targets 5-HT_2A serotonin receptors in the brain, decreasing their activity in order to attenuate hallucinations and delusions.

“Pimavanserin has been approved by the FDA [Food and Drug Administration] for Parkinson’s disease psychosis, but its safety has been called into question based on previous reports of increased mortality risk, compared with a rather modest benefit seen in a 6-week clinical trial, the duration of which limits determination of long-term safety,” wrote Dr. Ali.

Pimavanserin carries a boxed warning that elderly patients with dementia may be at an increased risk of death. After its approval in 2016, the U.S. FDA later reviewed 893 deaths in association with pimavanserin during the postmarketing surveillance period – “an unexpected number in a new drug,” Dr. Hwang and colleagues noted. “It [the FDA] noted that most reports occurred in a population with high underlying death rates and did not signal any additional risk beyond the current warning for all antipsychotics, which could have resulted in annual mortality rates of up to 60%.”

As the first cohort study to examine hospitalization and death between pimavanserin users and nonusers, “the study confirms previous concerns regarding safety of pimavanserin and more importantly brings to attention the importance of carefully considering risks and benefits of pharmacotherapy in Parkinson’s disease psychosis, clear communication with patients and families, and close observation to ensure safety,” wrote Dr. Ali.

The study limitations include its observational design, which subjected the findings to residual confounding.

“While we developed models to maximize the strength of causal inference, our comparison group was pimavanserin nonusers and the very reason for prescription of pimavanserin could have predisposed its users to the outcomes of hospitalization and death, introducing confounding by indication,” Dr. Hwang and colleagues wrote in the paper.

Additionally, “while robust analyses were conducted to ensure pimavanserin users and nonusers were comparable, Dr. Hwang et al. did find that pimavanserin users were more likely to concomitantly use other antipsychotic drugs which has been demonstrated as increasing the mortality risk,” Dr. Ali pointed out.

Since patients living in long-term care facilities may have a higher risk of mortality because of more severe or later-stage Parkinson’s disease, the study results “may not be generalizable to community-dwelling PD patients,” Dr. Ali wrote. “These factors are important to consider while making individual management decisions.”

Dr. Hwang and Dr. Ali disclosed no relevant financial relationships. The study authors reported no targeted funding.

Rates of minor diabetes-related lower extremity amputations (LEAs) in hospitalized patients increased between 2009 and 2017 in all racial and ethnic groups, in both rural and urban areas, and in all geographic regions across the United States, a new retrospective, observational study indicates.

In contrast, major lower extremity amputation rates held steady during the study period with a few exceptions.

There was also a decline in major-to-minor amputation ratios, especially among Native Americans – a sign that diabetes was being better managed and foot ulcers were being caught earlier, preventing the need for a major amputation above the foot or below or above the knee.

Minor LEAs include the loss of a toe, toes, or a foot.

“While I know an amputation is devastating either way, having a minor amputation is better than having a major amputation, and trends [at least to 2017] show that comprehensive foot examinations are paying off,” lead author Marvellous Akinlotan, PhD, MPH, a research associate at the Southwest Rural Health Research Center in Bryan, Texas, said in an interview.

Asked to comment, Marcia Ory, PhD, MPH, director of the Center for Population Health & Aging, Texas A&M School of Public Health, College Station, who was not involved in the study, said: “It points to some successes, but it also points to the need for continued education and preventive care to reduce all types of amputations.”

The study was published online in Diabetes Care.
 

Amputations increased during COVID-19

However, the study was conducted prior to the COVID-19 pandemic, and amputation rates appear to have significantly worsened during the past 18 months.

In a summary of recent evidence collated by the Amputee Coalition, the authors point out that not only does COVID-19 itself put patients at higher risk for limb loss because severe infection increases the risk of blood clots, but patients with diabetes appear to have been far more likely to undergo any level of amputation during the pandemic than before it began.

In a study of patients with diabetes attending a foot and ankle surgery service in Ohio, the risk of having any level of amputation was 10.8 times higher during compared with before the pandemic. And of patients undergoing any amputation, the odds for receiving a major amputation was 3.1 times higher than before the pandemic.

Telehealth and web-based options for diabetes care and education could help improve health outcomes, particularly during lockdowns.

“Having a diabetes-related amputation is life-changing – it brings disability and functional limitations to the individual – and within the health care system, it reflects the failure of secondary prevention efforts, which ideally should slow the progression of diabetic complications,” noted Dr. Akinlotan.
 

Race and geography affect risk of amputation

In their study, Dr. Akinlotan and colleagues used data from the National Inpatient Sample to identify trends in LEAs among patients primarily hospitalized for diabetes in the United States between 2009 and 2017.

“The primary outcome variable was documentation of either minor or major LEA during a diabetes-related admission,” they explain.

Minor LEAs increased significantly across all ethnic groups.

Spending more free time seated combined with engaging in low physical activity is associated with an increased risk of stroke in adults aged between 40 and 60 years, according to a new analysis.

While the risk of stroke increased more than fourfold among sedentary people under the age of 60, no significant increase in risk was observed among older individuals, according to the study based on self-reported data from more than 140,000 people. This highlights the need for relevant public health messaging directed at younger people, reported lead author, Raed A. Joundi, MD, DPhil, a stroke fellow at the University of Calgary (Alta.), and colleagues, in the paper published in Stroke.

“Sedentary time has increased over the past 2 decades in the United States and Canada, particularly in the young, raising the importance of characterizing its effect on long-term health , ” the investigators wrote. “A better understanding of the risk of sedentary time specific to stroke may be important for public health campaigns to reduce sedentary behavior.” Dr. Joundi and colleagues reviewed data from the Canadian Community Health Survey, including 143,180 healthy individuals without baseline history of cancer, heart disease, or stroke. Those under the age of 40 years were also excluded from the analysis.

Excess sedentary leisure time was defined as 8 or more hours of sedentary leisure time per day, whereas low physical activity was defined as less than 3.5 metabolic equivalent hours per week. The analysis also included a range of demographic and medical covariates, such as age, sex, marital status, smoking status, presence of hypertension, and others.

After a median follow-up of 9.4 years, 2,965 stroke events occurred, with a median time from survey response of 5.6 years. Risk of stroke among individuals aged younger than 60 years who engaged in low physical activity and excess sedentary leisure time was increased 4.5-fold, compared with individuals with low physical activity who were sedentary less than 4 hours per day (fully adjusted hazard ratio, 4.50; 95% confidence interval, 1.64-12.3).
 

Findings highlight benefits of physical activity

Similar risk elevations were not observed among individuals aged 60-79 years, or those older than 80. And among people younger than 60, high physical activity appeared to eliminate the additional risk imposed by excess sedentary leisure time.

“Sedentary time is associated with higher risk of stroke in inactive individuals, but not an active individual, ” Dr. Joundi said in an interview. “So it suggests that there’s two ways to lower risk: One would be to lower your sedentary time, and the other would be to engage in physical activity.”

These interpretations are speculative, Dr. Joundi cautioned, as the study was not interventional. Even so, he said that the findings “bring the spotlight back on physical activity,” thereby aligning with previous research.

“The more you exercise, the more that relationship between sedentary time and poor health outcomes is blunted, and in fact, can be completely negated with enough physical activity,” he said.

How exactly physical activity offers such protection remains unclear, Dr. Joundi added. He speculated that regularity of exercise may be key, with each session counteracting the adverse effects of prolonged sedentary time, which may include reduced blood flow, increased insulin resistance, and inflammatory changes that can affect blood vessels.

“This study is particularly a message for younger individuals,” Dr. Joundi said, suggesting that the findings may alter behavior, as many people have witnessed, or are aware of, the long-term impacts of stroke.

“There’s a sort of social or cognitive aversion to stroke, I think, in the general population, because of how disabling it can be, and how it can lower your quality of life,” he said.
 

Subtle lifestyle changes may be enough.

For those aiming to lower their risk of stroke, Dr. Joundi suggested that subtle lifestyle changes may be enough.

“Ultimately, what we saw is that even minimal amounts of physical activity – walking 3 hours a week, for example – could blunt the impact of sedentary time,” he said. “Doing what you can, even if it’s a small amount, tends to be quite meaningful over a long period of time.”

Daniel T. Lackland, DrPH, professor of epidemiology in the department of neurology at the Medical University of South Carolina, Charleston, offered a similar takeaway, noting that small efforts can lead to great benefits.

“Less intense activity is still better than being sedentary,” he said in an interview. “For many people, if you do get up and you just walk around, move your arms around – do any kind of movement – that’s better than being sedentary.”

Dr. Lackland applauded the practicality of studying sedentary leisure time, versus overall leisure time, as many people can’t control their work environment.

“You can’t do very much about how you work your job,” Dr. Lackland said. “Sometimes we have to sit, and I guess there are things you can do – you can put a treadmill instead of a chair and that kind of thing – but more often than not, you don’t really have that choice to do something. With leisure time, though, you’re in full control. And so what do you do with your leisure time? Do you sit and watch TV, or do you engage in some type of activity? Not necessarily aerobic activity, but some type of activity that would not let you be sedentary. You want to be active as much as you possibly can.”

Dr. Joundi disclosed grant support from the Canadian Institutes of Health Research. The other investigators and Dr. Lackland reported no relevant disclosures.

Those under the age of 40 years were also excluded from the analysis.

Excess sedentary leisure time was defined as 8 or more hours of sedentary leisure time per day, whereas low physical activity was defined as less than 3.5 metabolic equivalent hours per week. The analysis also included a range of demographic and medical covariates, such as age, sex, marital status, smoking status, presence of hypertension, and others.

After a median follow-up of 9.4 years, 2,965 stroke events occurred, with a median time from survey response of 5.6 years. Risk of stroke among individuals aged younger than 60 years who engaged in low physical activity and excess sedentary leisure time was increased 4.5-fold, compared with individuals with low physical activity who were sedentary less than 4 hours per day (fully adjusted hazard ratio, 4.50; 95% confidence interval, 1.64-12.3).
 

Findings highlight benefits of physical activity

Similar risk elevations were not observed among individuals aged 60-79 years, or those older than 80. And among people younger than 60, high physical activity appeared to eliminate the additional risk imposed by excess sedentary leisure time.

“Sedentary time is associated with higher risk of stroke in inactive individuals, but not an active individual, ” Dr. Joundi said in an interview. “So it suggests that there’s two ways to lower risk: One would be to lower your sedentary time, and the other would be to engage in physical activity.”

These interpretations are speculative, Dr. Joundi cautioned, as the study was not interventional. Even so, he said that the findings “bring the spotlight back on physical activity,” thereby aligning with previous research.

“The more you exercise, the more that relationship between sedentary time and poor health outcomes is blunted, and in fact, can be completely negated with enough physical activity,” he said.

How exactly physical activity offers such protection remains unclear, Dr. Joundi added. He speculated that regularity of exercise may be key, with each session counteracting the adverse effects of prolonged sedentary time, which may include reduced blood flow, increased insulin resistance, and inflammatory changes that can affect blood vessels.

“This study is particularly a message for younger individuals,” Dr. Joundi said, suggesting that the findings may alter behavior, as many people have witnessed, or are aware of, the long-term impacts of stroke.

“There’s a sort of social or cognitive aversion to stroke, I think, in the general population, because of how disabling it can be, and how it can lower your quality of life,” he said.
 

Subtle lifestyle changes may be enough.

For those aiming to lower their risk of stroke, Dr. Joundi suggested that subtle lifestyle changes may be enough.

“Ultimately, what we saw is that even minimal amounts of physical activity – walking 3 hours a week, for example – could blunt the impact of sedentary time,” he said. “Doing what you can, even if it’s a small amount, tends to be quite meaningful over a long period of time.”

Daniel T. Lackland, DrPH, professor of epidemiology in the department of neurology at the Medical University of South Carolina, Charleston, offered a similar takeaway, noting that small efforts can lead to great benefits.

“Less intense activity is still better than being sedentary,” he said in an interview. “For many people, if you do get up and you just walk around, move your arms around – do any kind of movement – that’s better than being sedentary.”

Dr. Lackland applauded the practicality of studying sedentary leisure time, versus overall leisure time, as many people can’t control their work environment.

“You can’t do very much about how you work your job,” Dr. Lackland said. “Sometimes we have to sit, and I guess there are things you can do – you can put a treadmill instead of a chair and that kind of thing – but more often than not, you don’t really have that choice to do something. With leisure time, though, you’re in full control. And so what do you do with your leisure time? Do you sit and watch TV, or do you engage in some type of activity? Not necessarily aerobic activity, but some type of activity that would not let you be sedentary. You want to be active as much as you possibly can.”

Spending more free time seated combined with engaging in low physical activity is associated with an increased risk of stroke in adults aged between 40 and 60 years, according to a new analysis.

While the risk of stroke increased more than fourfold among sedentary people under the age of 60, no significant increase in risk was observed among older individuals, according to the study based on self-reported data from more than 140,000 people. This highlights the need for relevant public health messaging directed at younger people, reported lead author, Raed A. Joundi, MD, DPhil, a stroke fellow at the University of Calgary (Alta.), and colleagues, in the paper published in Stroke.

Preterm and early birth is associated with an increased risk of autism independent of genetic or environmental factors, according to new research published in Pediatrics.

Although previous studies have linked preterm births to an increased risk of autism – one 2017 study published in Cerebral Cortex found that 27.4% of the children born extremely preterm were diagnosed with autism – Casey Crump, MD, PhD, said potential causality, sex-specific differences, and association with early-term births were still unclear.

“Preterm birth had previously been linked with higher risk of autism; however, several important questions remained unanswered,” said Dr. Crump, professor and vice chair for research at the department of family medicine and community health and professor of epidemiology in the department of population health science and policy at Icahn School of Medicine at Mount Sinai New York. “To our knowledge, [our study] is the largest to date of gestational age at birth in relation to autism, and one of the first to investigate sex-specific differences, early term birth, or the influence of shared familial factors.”

Dr. Crump and colleagues examined data from more than 4 million infants born in Sweden between 1973 and 2013 who were followed-up for autism spectrum disorder identified from nationwide outpatient and inpatient diagnoses through December 2015. Children born between 22 and 27 weeks were considered extremely preterm, those born between 28 and 33 week were characterized as very to moderate preterm, and those born between 34 and 36 weeks were considered late preterm. Early-term births are characterized as infants born between 37 and 38 weeks and children born between 39 and 41 weeks were considered term births.

They found that 6.1% of those born extremely preterm were diagnosed with autism. Meanwhile, autism spectrum disorder prevalences were 2.6% for very to moderate preterm, 1.9% for late preterm, 2.1% for all preterm, and 1.6% for early term, compared with 1.4% for term birth.

The researchers’ analysis showed that preterm and early birth were associated with a significantly increased risk of autism in males and females. Children who were born extremely preterm had an approximately fourfold increased risk of autism. Researchers also found that each additional week of gestation was associated with a 5% lower prevalence of autism spectrum disorder (ASD) on average.

“The elevated risk even in [late preterm] infants is not completely surprising because a number of investigators have shown higher incidences of early cognitive, language motor and impairment, and school problems ... and psychiatric disorders, some of which may extend to adulthood,” Elisabeth McGowan, MD, who was not involved in the study, said in a solicited editorial commentary about the study.

Dr. Crump believes the association between preterm birth and autism may be because of increased inflammatory marker levels. A 2009 study published in Reproductive Sciences found that increased proinflammatory cytokine levels have been associated with the timing and initiation of preterm birth, and also have been detected in the brain and cerebrospinal fluid of individuals with autism “and may play a key role in its pathogenesis,” Dr. Crump said.

“Inflammatory-driven alteration of neuronal connections during critical periods of brain development may be central to the development of autism,” Dr. Crump explained.

However, Dr. Crump said that, although the relative risks of autism were higher in those born preterm, the absolute risk of the condition is low.

“The report by Crump is in many ways a definitive accounting of the elevated rates of ASD in preterm infants,” said Dr. McGowan, associate professor of pediatrics at the Women and Infants Hospital, Providence, R.I. “And although the impact of prematurity on brain development may be part of the causal chain resulting in ASD (or other neurodevelopmental outcomes), these factors are operating in a complex biological landscape, with pathways to ASD outcomes that can be expected to be heterogeneous.”

ASD is a developmental condition that affects about 1 in 54 children, according to the Centers for Disease Control and Prevention. Many children are not diagnosed with ASD until later in childhood, which in some cases delays treatment and early intervention. ASD may be detected as early as 18 months, but the average age of diagnosis for ASD is 4.3 years, according to the CDC.

“Children born prematurely need early evaluation and long-term follow-up to facilitate timely detection and treatment of autism, especially those born at the earliest gestational ages,” Dr. Crump said in an interview. “In patients of all ages, gestational age at birth should be routinely included in history-taking and medical records to help identify in clinical practice those born preterm or early term. Such information can provide additional valuable context for understanding patients’ health and may facilitate earlier evaluation for autism and other neurodevelopmental conditions in those born prematurely.”

Dr. Crump and colleagues said more research is needed to understand the biologic mechanisms linking preterm birth with higher risks of autism, which “may reveal new targets for intervention at critical windows of neurodevelopment to improve the disease trajectory.”

Experts interviewed did not disclose any relevant financial relationships.

Second-generation antipsychotics (SGAs) taken by pregnant women are linked to a low rate of adverse effects in their children, new research suggests.

monkeybusinessimages/Thinkstock

Data from a large registry study of almost 2,000 women showed that 2.5% of the live births in a group that had been exposed to antipsychotics had confirmed major malformations compared with 2% of the live births in a non-exposed group. This translated into an estimated odds ratio of 1.5 for major malformations.

“The 2.5% absolute risk for major malformations is consistent with the estimates of the Centers for Disease Control and Prevention’s national baseline rate of major malformations in the general population,” lead author Adele Viguera, MD, MPH, director of research for women’s mental health, Cleveland Clinic Neurological Institute, told this news organization.

“Our results are reassuring and suggest that second-generation antipsychotics, as a class, do not substantially increase the risk of major malformations,” Dr. Viguera said.

The findings were published online August 3 in the Journal of Clinical Psychiatry.
 

Safety data scarce

Despite the increasing use of SGAs to treat a “spectrum of psychiatric disorders,” relatively little data are available on the reproductive safety of these agents, Dr. Viguera said.

The National Pregnancy Registry for Atypical Antipsychotics (NPRAA) was established in 2008 to determine risk for major malformation among infants exposed to these medications during the first trimester, relative to a comparison group of unexposed infants of mothers with histories of psychiatric morbidity.

The NPRAA follows pregnant women (aged 18 to 45 years) with psychiatric illness who are exposed or unexposed to SGAs during pregnancy. Participants are recruited through nationwide provider referral, self-referral, and advertisement through the Massachusetts General Hospital Center for Women’s Mental Health website.

The women are interviewed by phone at three timepoints: Enrollment, 7 months, and 3 months postpartum. Specific data collected are shown in the following table.

Demographic differences

Of the 1,906 women who enrolled as of April 2020, 1,311 (mean age, 32.6 years; 81.3% White) completed the study and were eligible for inclusion in the analysis.

Although the groups had a virtually identical mean age, fewer women in the exposure group were married compared with those in the non-exposure group (77% vs. 90%, respectively) and fewer had a college education (71.2% vs. 87.8%). There was also a higher percentage of first-trimester cigarette smokers in the exposure group (18.4% vs. 5.1%).

On the other hand, more women in the non-exposure group used alcohol than in the exposure group (28.6% vs. 21.4%, respectively).

The most frequent psychiatric disorder in the exposure group was bipolar disorder (63.9%), followed by major depression (12.9%), anxiety (5.8%), and schizophrenia (4.5%). Only 11.4% of women in the non-exposure group were diagnosed with bipolar disorder, whereas 34.1% were diagnosed with major depression, 31.3% with anxiety, and none with schizophrenia.

Notably, a large percentage of women in both groups had a history of postpartum depression and/or psychosis (41.4% and 35.5%, respectively).

The most frequently used SGAs in the exposure group were quetiapine (Seroquel), aripiprazole (Abilify), and lurasidone (Latuda).

Participants in the exposure group had a higher age at initial onset of primary psychiatric diagnosis and a lower proportion of lifetime illness compared with those in the non-exposure group.
 

Major clinical implication?

Among 640 live births in the exposure group, which included 17 twin pregnancies and 1 triplet pregnancy, 2.5% reported major malformations. Among 704 live births in the control group, which included 14 twin pregnancies, 1.99% reported major malformations.

The estimated OR for major malformations comparing exposed and unexposed infants was 1.48 (95% confidence interval, 0.625-3.517).

The authors note that their findings were consistent with one of the largest studies to date, which included a nationwide sample of more than 1 million women. Its results showed that, among infants exposed to SGAs versus those who were not exposed, the estimated risk ratio after adjusting for psychiatric conditions was 1.05 (95% CI, 0.96-1.16).

Additionally, “a hallmark of a teratogen is that it tends to cause a specific type or pattern of malformations, and we found no preponderance of one single type of major malformation or specific pattern of malformations among the exposed and unexposed groups,” Dr. Viguera said

“A major clinical implication of these findings is that for women with major mood and/or psychotic disorders, treatment with an atypical antipsychotic during pregnancy may be the most prudent clinical decision, much as continued treatment is recommended for pregnant women with other serious and chronic medical conditions, such as epilepsy,” she added.
 

The concept of ‘satisficing’

Commenting on the study, Vivien Burt, MD, PhD, founder and director/consultant of the Women’s Life Center at the Resnick University of California, Los Angeles (UCLA) Neuropsychiatric Hospital, called the findings “reassuring.”

The results “support the conclusion that in pregnant women with serious psychiatric illnesses, the use of SGAs is often a better option than avoiding these medications and exposing both the women and their offspring to the adverse consequences of maternal mental illness,” she said.

An accompanying editorial co-authored by Dr. Burt and colleague Sonya Rasminsky, MD, introduced the concept of “satisficing” – a term coined by Herbert Simon, a behavioral economist and Nobel Laureate. “Satisficing” is a “decision-making strategy that aims for a satisfactory (‘good enough’) outcome rather than a perfect one.”

The concept applies to decision-making beyond the field of economics “and is critical to how physicians help patients make decisions when they are faced with multiple treatment options,” said Dr. Burt, a professor emeritus of psychiatry at UCLA.

“The goal of ‘satisficing’ is to plan for the most satisfactory outcome, knowing that there are always unknowns, so in an uncertain world, clinicians should carefully help their patients make decisions that will allow them to achieve an outcome they can best live with,” she noted.

The investigators note that their findings may not be generalizable to the larger population of women taking SGAs, given that their participants were “overwhelmingly White, married, and well-educated women.”

They add that enrollment into the NPRAA registry is ongoing and larger sample sizes will “further narrow the confidence interval around the risk estimates and allow for adjustment of likely sources of confounding.”

The NPRAA is supported by Alkermes, Johnson & Johnson/Janssen Pharmaceuticals, Otsuka America Pharmaceutical, Sunovion Pharmaceuticals, SAGE Therapeutics, Teva Pharmaceuticals, and Aurobindo Pharma. Past sponsors of the NPRAA are listed in the original paper.

The most frequently used SGAs in the exposure group were quetiapine (Seroquel), aripiprazole (Abilify), and lurasidone (Latuda).

Participants in the exposure group had a higher age at initial onset of primary psychiatric diagnosis and a lower proportion of lifetime illness compared with those in the non-exposure group.
 

Major clinical implication?

Among 640 live births in the exposure group, which included 17 twin pregnancies and 1 triplet pregnancy, 2.5% reported major malformations. Among 704 live births in the control group, which included 14 twin pregnancies, 1.99% reported major malformations.

The estimated OR for major malformations comparing exposed and unexposed infants was 1.48 (95% confidence interval, 0.625-3.517).

The authors note that their findings were consistent with one of the largest studies to date, which included a nationwide sample of more than 1 million women. Its results showed that, among infants exposed to SGAs versus those who were not exposed, the estimated risk ratio after adjusting for psychiatric conditions was 1.05 (95% CI, 0.96-1.16).

Additionally, “a hallmark of a teratogen is that it tends to cause a specific type or pattern of malformations, and we found no preponderance of one single type of major malformation or specific pattern of malformations among the exposed and unexposed groups,” Dr. Viguera said

“A major clinical implication of these findings is that for women with major mood and/or psychotic disorders, treatment with an atypical antipsychotic during pregnancy may be the most prudent clinical decision, much as continued treatment is recommended for pregnant women with other serious and chronic medical conditions, such as epilepsy,” she added.
 

The concept of ‘satisficing’

Commenting on the study, Vivien Burt, MD, PhD, founder and director/consultant of the Women’s Life Center at the Resnick University of California, Los Angeles (UCLA) Neuropsychiatric Hospital, called the findings “reassuring.”

The results “support the conclusion that in pregnant women with serious psychiatric illnesses, the use of SGAs is often a better option than avoiding these medications and exposing both the women and their offspring to the adverse consequences of maternal mental illness,” she said.

An accompanying editorial co-authored by Dr. Burt and colleague Sonya Rasminsky, MD, introduced the concept of “satisficing” – a term coined by Herbert Simon, a behavioral economist and Nobel Laureate. “Satisficing” is a “decision-making strategy that aims for a satisfactory (‘good enough’) outcome rather than a perfect one.”

The concept applies to decision-making beyond the field of economics “and is critical to how physicians help patients make decisions when they are faced with multiple treatment options,” said Dr. Burt, a professor emeritus of psychiatry at UCLA.

“The goal of ‘satisficing’ is to plan for the most satisfactory outcome, knowing that there are always unknowns, so in an uncertain world, clinicians should carefully help their patients make decisions that will allow them to achieve an outcome they can best live with,” she noted.

The investigators note that their findings may not be generalizable to the larger population of women taking SGAs, given that their participants were “overwhelmingly White, married, and well-educated women.”

They add that enrollment into the NPRAA registry is ongoing and larger sample sizes will “further narrow the confidence interval around the risk estimates and allow for adjustment of likely sources of confounding.”

Second-generation antipsychotics (SGAs) taken by pregnant women are linked to a low rate of adverse effects in their children, new research suggests.

monkeybusinessimages/Thinkstock

Data from a large registry study of almost 2,000 women showed that 2.5% of the live births in a group that had been exposed to antipsychotics had confirmed major malformations compared with 2% of the live births in a non-exposed group. This translated into an estimated odds ratio of 1.5 for major malformations.

“The 2.5% absolute risk for major malformations is consistent with the estimates of the Centers for Disease Control and Prevention’s national baseline rate of major malformations in the general population,” lead author Adele Viguera, MD, MPH, director of research for women’s mental health, Cleveland Clinic Neurological Institute, told this news organization.

“Our results are reassuring and suggest that second-generation antipsychotics, as a class, do not substantially increase the risk of major malformations,” Dr. Viguera said.

The findings were published online August 3 in the Journal of Clinical Psychiatry.
 

Safety data scarce

Despite the increasing use of SGAs to treat a “spectrum of psychiatric disorders,” relatively little data are available on the reproductive safety of these agents, Dr. Viguera said.

The National Pregnancy Registry for Atypical Antipsychotics (NPRAA) was established in 2008 to determine risk for major malformation among infants exposed to these medications during the first trimester, relative to a comparison group of unexposed infants of mothers with histories of psychiatric morbidity.

The NPRAA follows pregnant women (aged 18 to 45 years) with psychiatric illness who are exposed or unexposed to SGAs during pregnancy. Participants are recruited through nationwide provider referral, self-referral, and advertisement through the Massachusetts General Hospital Center for Women’s Mental Health website.

The women are interviewed by phone at three timepoints: Enrollment, 7 months, and 3 months postpartum. Specific data collected are shown in the following table.

Demographic differences

Of the 1,906 women who enrolled as of April 2020, 1,311 (mean age, 32.6 years; 81.3% White) completed the study and were eligible for inclusion in the analysis.

Although the groups had a virtually identical mean age, fewer women in the exposure group were married compared with those in the non-exposure group (77% vs. 90%, respectively) and fewer had a college education (71.2% vs. 87.8%). There was also a higher percentage of first-trimester cigarette smokers in the exposure group (18.4% vs. 5.1%).

On the other hand, more women in the non-exposure group used alcohol than in the exposure group (28.6% vs. 21.4%, respectively).

The most frequent psychiatric disorder in the exposure group was bipolar disorder (63.9%), followed by major depression (12.9%), anxiety (5.8%), and schizophrenia (4.5%). Only 11.4% of women in the non-exposure group were diagnosed with bipolar disorder, whereas 34.1% were diagnosed with major depression, 31.3% with anxiety, and none with schizophrenia.

Notably, a large percentage of women in both groups had a history of postpartum depression and/or psychosis (41.4% and 35.5%, respectively).

The most frequently used SGAs in the exposure group were quetiapine (Seroquel), aripiprazole (Abilify), and lurasidone (Latuda).

There is currently no evidence that newer antiseizure medications increase the risk for suicide among patients with epilepsy, new research shows. “There appears to be no justification for the FDA to label every new antiseizure medication with a warning that it may increase risk of suicidality,” said study investigator Michael R. Sperling, MD, professor of neurology, Thomas Jefferson University, Philadelphia.

“How many patients are afraid of their medication and do not take it because of the warning – and are consequently at risk because of that? We do not know, but have anecdotal experience that this is certainly an issue,” Dr. Sperling, who is director of the Jefferson Comprehensive Epilepsy Center, added.

The study was published online August 2 in JAMA Neurology.
 

Blanket warning

In 2008, the FDA issued an alert stating that antiseizure medications increase suicidality. The alert was based on pooled data from placebo-controlled clinical trials that included 11 antiseizure medications – carbamazepine, felbamate, gabapentin, lamotrigine, levetiracetam, oxcarbazepine, pregabalin, tiagabine, topiramate, valproate, and zonisamide.

The meta-analytic review showed that, compared with placebo, antiseizure medications nearly doubled suicide risk among patients treated for epilepsy, psychiatric disorders, and other diseases. As a result of the FDA study, all antiseizure medications that have been approved since 2008 carry a warning for suicidality.

However, subsequent analyses did not show the same results, Dr. Sperling and colleagues noted.

“Pivotal” antiseizure medication epilepsy trials since 2008 have evaluated suicidality prospectively. Since 2011, trials have included the validated Columbia Suicidality Severity Rating Scale, they noted.
 

Meta analysis showed no increased risk

Dr. Sperling and colleagues conducted a meta-analysis of 17 randomized placebo-controlled epilepsy trials of five antiseizure medications approved since 2008. These antiseizure medications were eslicarbazepine, perampanel, brivaracetam, cannabidiol, and cenobamate. The trials involved 5,996 patients, including 4,000 who were treated with antiseizure medications and 1,996 who were treated with placebo.

Confining the analysis to epilepsy trials avoids potential confounders, such as possible differences in suicidality risks between different diseases, the researchers noted.

They found no evidence of increased risk for suicidal ideation (overall risk ratio, antiseizure medications vs. placebo: 0.75; 95% confidence interval: 0.35-1.60) or suicide attempt (risk ratio, 0.75; 95% CI: 0.30-1.87) overall or for any individual antiseizure medication.

Suicidal ideation occurred in 12 of 4,000 patients treated with antiseizure medications (0.30%), versus 7 of 1,996 patients treated with placebo (0.35%) (P = .74). Three patients who were treated with antiseizure medications attempted suicide; no patients who were treated with placebo attempted suicide (P = .22). There were no completed suicides.

“There is no current evidence that the five antiseizure medications evaluated in this study increase suicidality in epilepsy and merit a suicidality class warning,” the investigators wrote. When prescribed for epilepsy, “evidence does not support the FDA’s labeling practice of a blanket assumption of increased suicidality,” said Dr. Sperling.

“Our findings indicate the nonspecific suicide warning for all epilepsy drugs is simply not justifiable,” he said. “The results are not surprising. Different drugs affect cells in different ways. So there’s no reason to expect that every drug would increase suicide risk for every patient,” Dr. Sperling said in a statement.

“It’s important to recognize that epilepsy has many causes – perinatal injury, stroke, tumor, head trauma, developmental malformations, genetic causes, and others – and these underlying etiologies may well contribute to the presence of depression and suicidality in this population,” he said in an interview. “Psychodynamic influences also may occur as a consequence of having seizures. This is a complicated area, and drugs are simply one piece of the puzzle,” he added.

Dr. Sperling said the FDA has accomplished “one useful thing with its warning – it highlighted that physicians and other health care providers must pay attention to their patients’ psychological state, ask questions, and treat accordingly.”

The study had no specific funding. Dr. Sperling has received grants from Eisai, Medtronic, Neurelis, SK Life Science, Sunovion, Takeda, Xenon, Cerevel Therapeutics, UCB Pharma, and Engage Pharma; personal fees from Neurelis, Medscape, Neurology Live, International Medical Press, UCB Pharma, Eisai, Oxford University Press, and Projects in Knowledge. He has also consulted for Medtronic outside the submitted work; payments went to Thomas Jefferson University. A complete list of authors’ disclosures is available with the original article.

Wisdom increases with age, and although this personality trait is regarded as nebulous by many, there is evidence that it has biological and neuropsychiatric underpinnings. It could even hold the key to reducing loneliness and burnout among older people.

Courtesy Dr. Tanya T. Nguyen

Those were some of the key messages delivered by Tanya T. Nguyen, PhD, of the department of psychiatry at the University of California, San Diego, who spoke at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

“To many people, wisdom remains a fuzzy concept that’s difficult to operationalize and measure. It’s analogous to the concepts of consciousness, emotions, and cognitions, which at one point were considered nonscientific, but today we accept them as biological and scientific entities,” Dr. Nguyen said during her talk at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.

Interest in quantifying and studying wisdom has picked up in recent years, and Dr. Nguyen gave a definition with six elements that includes prosocial behaviors such as empathy and compassion, as well as emotional regulation, self-reflection, decisiveness, and social decision-making. She also included a spirituality component, though she conceded that this is controversial.

She noted that there are cultural variations in the definition of wisdom, but it has changed little over time, suggesting that it may be biological rather than cultural in nature, and therefore may have a neuropsychiatric underpinning.

Loss of some or all characteristics of wisdom occurs in some behaviors and disorders, including most markedly in the neurodegenerative disorder frontotemporal dementia (FTD), which is characterized by damage only in the prefrontal cortex and anterior temporal lobes. It usually occurs before age 60, and patients exhibit poor social awareness, impulsivity, antisocial behavior, and a lack of insight and empathy.

This and other lines of evidence have led to the suggestion that wisdom may be governed by processes in the prefrontal cortex and the limbic striatum. The prefrontal cortex controls executive functions such as planning, predicting, and anticipating events, as well as managing emotional reactions and impulses. “Thus, wisdom involves parts of the brain that balance cold, hard analytical reasoning with primitive desires and drives, which ultimately leads to self-regulation, social insight, theory of mind, and empathy,” said Dr. Nguyen.

Wisdom has long been associated with age, but age is also linked to cognitive decline. A recent discovery that the brain does not stop evolving at older age may help explain this contradiction. Brains develop in a back to front order, so that the prefrontal cortex is the last to mature. As we age, neural activity shifts from the occipital lobes to the prefrontal cortex and its executive decision-making power.

“The brain may recruit higher-order networks to the prefrontal cortex that are associated with wisdom development,” said Dr. Nguyen. She also pointed out that asymmetry between the left and right hemisphere is reduced with age, as tasks that relied on circuits from one hemisphere or another more often call upon both. “In order to make up for lost synapses and neurons with aging, active older adults use more neuronal networks from both hemispheres to perform the same mental activity,” Dr. Nguyen said.

Some interventions can improve scores in traits associated with wisdom in older adults, and could be an important contributor to improvements in health and longevity, said Dr. Nguyen. Randomized, controlled trials have demonstrated that psychosocial or behavioral interventions can improve elements of wisdom such as prosocial behaviors and emotional regulation, both in people with mental illness and in the general population, with moderate to large effect sizes. But such studies don’t prove an effect on overall wisdom.

Dr. Nguyen’s group tested a manualized intervention called Raise Your Resilience, which attempts to improve wisdom, resilience, and perceived stress through engagement in value-based activities. The intervention achieved positive results in 89 participants in senior housing communities, though the effect sizes were small, possibly because of high baseline resilience. A subanalysis suggested that reduction in loneliness was mediated by an increase in compassion.

“One of the most striking findings from our research on wisdom is this consistent and very strongly negative correlation between wisdom and loneliness,” Dr. Nguyen said. She highlighted other U.S. nationwide and cross-cultural studies that showed inverse relationships between loneliness and wisdom.

Loneliness is an important topic because it can contribute to burnout and suicide rates.

“Loneliness has a profound effect on how we show up in the workplace, in school, and in our communities. And that leads to anxiety, depression, depersonalization, and emotional fatigue. All are key features of burnout. And together loneliness and burnout have contributed to increased rates of suicide by 30%, and opioid-related deaths almost sixfold since the late 1990s,” Dr. Nguyen said.

Loneliness also is associated with worse physical health, and it may be linked to wisdom. “Loneliness can be conceptualized as being caused and maintained by objective circumstances, such as physical or social distancing, and by thoughts, behaviors, and feelings surrounding those experiences, including biased perceptions of social relations, and a negative assessment of one’s social skills, which then results in a discrepancy between one’s desired and perceived social relationships, which then can contribute to social withdrawal,” Dr. Nguyen said.

Dr. Nguyen highlighted the AARP Foundation’s Experience Corps program, which recruits older adults to act as mentors and tutors for children in kindergarten through third grade. It involves 15 hours per week over an entire school year, with a focus on child literacy, development, and behavioral management skills. A study revealed a significant impact. “It showed improvements in children’s grades and happiness, as well as seniors’ mental and physical health,” Dr. Nguyen said.

Dr. Nguyen concluded that wisdom “may be a vaccine against compassion fatigue and burnout that drive today’s behavioral epidemics of loneliness, opioid abuse, and suicide. It’s a tool for our times. It’s nuanced, flexible, pragmatic, compassionate, and it presents a reasonable framework for getting along in the often messy world that we all share.”
 

Implications for psychiatrists

Henry A. Nasrallah, MD, who organized the conference, suggested that the benefits of wisdom may not be limited to patients. He pointed out that surgeons often retire at age 60 or 65 because of declining physical skills, while psychiatrists continue to practice.

“We develop more wisdom and better skills, and we can practice into our 60s and 70s. I know psychiatrists who practice sometimes into their 80s. It’s really a wonderful thing to know that what you do in life develops or enhances the neuroplasticity of certain brain regions. In our case, in psychiatry, it is the brain regions involved in wisdom,” commented Dr. Nasrallah, who is a professor of psychiatry, neurology, and neuroscience at the University of Cincinnati.

Dr. Nguyen has no financial disclosures. Dr. Nasrallah has received grants from Abbott, AstraZeneca, Forest, Janssen, Lilly, Pfizer, and Shire, and advises Abbott, AstraZeneca, and Shire.

Wisdom increases with age, and although this personality trait is regarded as nebulous by many, there is evidence that it has biological and neuropsychiatric underpinnings. It could even hold the key to reducing loneliness and burnout among older people.

Loss of some or all characteristics of wisdom occurs in some behaviors and disorders, including most markedly in the neurodegenerative disorder frontotemporal dementia (FTD), which is characterized by damage only in the prefrontal cortex and anterior temporal lobes. It usually occurs before age 60, and patients exhibit poor social awareness, impulsivity, antisocial behavior, and a lack of insight and empathy.

This and other lines of evidence have led to the suggestion that wisdom may be governed by processes in the prefrontal cortex and the limbic striatum. The prefrontal cortex controls executive functions such as planning, predicting, and anticipating events, as well as managing emotional reactions and impulses. “Thus, wisdom involves parts of the brain that balance cold, hard analytical reasoning with primitive desires and drives, which ultimately leads to self-regulation, social insight, theory of mind, and empathy,” said Dr. Nguyen.

Wisdom has long been associated with age, but age is also linked to cognitive decline. A recent discovery that the brain does not stop evolving at older age may help explain this contradiction. Brains develop in a back to front order, so that the prefrontal cortex is the last to mature. As we age, neural activity shifts from the occipital lobes to the prefrontal cortex and its executive decision-making power.

“The brain may recruit higher-order networks to the prefrontal cortex that are associated with wisdom development,” said Dr. Nguyen. She also pointed out that asymmetry between the left and right hemisphere is reduced with age, as tasks that relied on circuits from one hemisphere or another more often call upon both. “In order to make up for lost synapses and neurons with aging, active older adults use more neuronal networks from both hemispheres to perform the same mental activity,” Dr. Nguyen said.

Some interventions can improve scores in traits associated with wisdom in older adults, and could be an important contributor to improvements in health and longevity, said Dr. Nguyen. Randomized, controlled trials have demonstrated that psychosocial or behavioral interventions can improve elements of wisdom such as prosocial behaviors and emotional regulation, both in people with mental illness and in the general population, with moderate to large effect sizes. But such studies don’t prove an effect on overall wisdom.

Dr. Nguyen’s group tested a manualized intervention called Raise Your Resilience, which attempts to improve wisdom, resilience, and perceived stress through engagement in value-based activities. The intervention achieved positive results in 89 participants in senior housing communities, though the effect sizes were small, possibly because of high baseline resilience. A subanalysis suggested that reduction in loneliness was mediated by an increase in compassion.

“One of the most striking findings from our research on wisdom is this consistent and very strongly negative correlation between wisdom and loneliness,” Dr. Nguyen said. She highlighted other U.S. nationwide and cross-cultural studies that showed inverse relationships between loneliness and wisdom.

Loneliness is an important topic because it can contribute to burnout and suicide rates.

“Loneliness has a profound effect on how we show up in the workplace, in school, and in our communities. And that leads to anxiety, depression, depersonalization, and emotional fatigue. All are key features of burnout. And together loneliness and burnout have contributed to increased rates of suicide by 30%, and opioid-related deaths almost sixfold since the late 1990s,” Dr. Nguyen said.

Loneliness also is associated with worse physical health, and it may be linked to wisdom. “Loneliness can be conceptualized as being caused and maintained by objective circumstances, such as physical or social distancing, and by thoughts, behaviors, and feelings surrounding those experiences, including biased perceptions of social relations, and a negative assessment of one’s social skills, which then results in a discrepancy between one’s desired and perceived social relationships, which then can contribute to social withdrawal,” Dr. Nguyen said.

Dr. Nguyen highlighted the AARP Foundation’s Experience Corps program, which recruits older adults to act as mentors and tutors for children in kindergarten through third grade. It involves 15 hours per week over an entire school year, with a focus on child literacy, development, and behavioral management skills. A study revealed a significant impact. “It showed improvements in children’s grades and happiness, as well as seniors’ mental and physical health,” Dr. Nguyen said.

Dr. Nguyen concluded that wisdom “may be a vaccine against compassion fatigue and burnout that drive today’s behavioral epidemics of loneliness, opioid abuse, and suicide. It’s a tool for our times. It’s nuanced, flexible, pragmatic, compassionate, and it presents a reasonable framework for getting along in the often messy world that we all share.”
 

Implications for psychiatrists

Henry A. Nasrallah, MD, who organized the conference, suggested that the benefits of wisdom may not be limited to patients. He pointed out that surgeons often retire at age 60 or 65 because of declining physical skills, while psychiatrists continue to practice.

“We develop more wisdom and better skills, and we can practice into our 60s and 70s. I know psychiatrists who practice sometimes into their 80s. It’s really a wonderful thing to know that what you do in life develops or enhances the neuroplasticity of certain brain regions. In our case, in psychiatry, it is the brain regions involved in wisdom,” commented Dr. Nasrallah, who is a professor of psychiatry, neurology, and neuroscience at the University of Cincinnati.

Wisdom increases with age, and although this personality trait is regarded as nebulous by many, there is evidence that it has biological and neuropsychiatric underpinnings. It could even hold the key to reducing loneliness and burnout among older people.

Those were some of the key messages delivered by Tanya T. Nguyen, PhD, of the department of psychiatry at the University of California, San Diego, who spoke at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

“To many people, wisdom remains a fuzzy concept that’s difficult to operationalize and measure. It’s analogous to the concepts of consciousness, emotions, and cognitions, which at one point were considered nonscientific, but today we accept them as biological and scientific entities,” Dr. Nguyen said during her talk at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.

Interest in quantifying and studying wisdom has picked up in recent years, and Dr. Nguyen gave a definition with six elements that includes prosocial behaviors such as empathy and compassion, as well as emotional regulation, self-reflection, decisiveness, and social decision-making. She also included a spirituality component, though she conceded that this is controversial.

She noted that there are cultural variations in the definition of wisdom, but it has changed little over time, suggesting that it may be biological rather than cultural in nature, and therefore may have a neuropsychiatric underpinning.
