The death ‘dog’

Imagine you’re out in your backyard managing the grill for a big family barbecue. You’ve got a dazzling assortment of meat assorted on your fancy new propane grill, all charring nicely. Naturally, the hot dogs finish first, and as you pull them off, you figure you’ll help yourself to one now. After all, you are the chef, you deserve a reward. But, as you bite into your smoking hot sandwich, a cold, bony finger taps you on the shoulder. You turn and come face to face with the Grim Reaper. “YOU JUST LOST 36 MINUTES,” Death says. “ALSO, MAY I HAVE ONE OF THOSE? THEY LOOK DELICIOUS.”

Nonplussed and moving automatically, you scoop up another hot dog and place it in a bun. “WITH KETCHUP PLEASE,” Death says. “I NEVER CARED FOR MUSTARD.”

“I don’t understand,” you say. “Surely I won’t die at a family barbecue.”

“DO NOT CALL ME SHIRLEY,” Death says. “AND YOU WILL NOT. IT’S PART OF MY NEW CONTRACT.”

A new study, published in Nature Food, found that a person may lose up to 36 minutes for every hot dog consumed. Researchers from the University of Michigan analyzed nearly 6,000 different foods using a new nutritional index to quantify their health effects in minutes of healthy life lost or gained. Eating a serving of nuts adds an extra 26 minutes of life. The researchers determined that replacing just 10% of daily caloric intake from beef and processed foods with fruits, vegetables, and nuts can add 48 minutes per day. It would also reduce the daily carbon footprint by 33%.

“So you go around to everyone eating bad food and tell them how much life they’ve lost?” you ask when the Grim Reaper finishes his story. “Sounds like a drag.”

“IT IS. WE’VE HAD TO HIRE NEW BLOOD.” Death chuckles at its own bad pun. “NOW IF YOU’LL EXCUSE ME, I MUST CHASTISE A MAN IN FLORIDA FOR EATING A WELL-DONE STEAK.”
 

More stress, less sex

As the world becomes a more stressful place, the human population could face a 50% drop by the end of the century.

Think of stress as a one-two punch to the libido and human fertility. The more people are stressed out, the less likely they are to have quality interactions with others. Many of us would rather be alone with our wine and cheese to watch our favorite show.

Researchers have found that high stress levels have been known to drop sperm count, ovulation, and sexual activity. Guess what? There has been a 50% decrease in sperm counts over the last 50 years. That’s the second punch. But let’s not forget, the times are changing.

“Changes in reproductive behavior that contribute to the population drop include more young couples choosing to be ‘child-free,’ people having fewer children, and couples waiting longer to start families,” said Alexander Suvorov, PhD, of the University of Massachusetts, the paper’s author.

Let’s summarize: The more stress we’re dealing with, the less people want to deal with each other.

Who would have thought the future would be less fun?

This week’s preshow match-off involves face mask woes. The first comes to us from Alabama, where a woman wore a space helmet to a school board meeting to protest mask mandates. The second comes from Australia, in the form of mischievous magpies. We will explain.

It is not uncommon for magpies to attack those who come too close to their nests in the spring, or “swooping season,” as it’s affectionately called. The magpies are smart enough to recognize the faces of people they see regularly and not attack; however, it’s feared that mask wearing will change this.

While you’re chewing on that exciting appetizer, let’s take a look at our main course, which has a distinct governmental flavor. Jeff Landry is the attorney general of Louisiana, and, like our space-helmet wearer, he’s not a fan of mask mandates. According to Business Insider, Mr. Landry “drafted and distributed sample letters intended to help parents evade mask-wearing ordinances and COVID-19 vaccination requirements for their children in schools.”

Up against him is the Food and Drug Administration’s Twitter account. In an unrelated matter, the agency tweeted, “You are not a horse. You are not a cow. Seriously, y’all. Stop it.” This was in response to people using the nonhuman forms of ivermectin to treat very human COVID-19.

Well, there you have it. Who will win tonight’s exciting edition of Pandemic Pandemonium? The first reader to contact us gets to decide the fate of these worthy contestants.
 

From venomous poison to heart drug

It’s not likely that anyone who sees a giant, venomous spider is thinking, “Hey! That thing could save my life!” It’s usually quite the opposite. Honestly, we would run away from just about any spider. But what if one of the deadliest spiders in the world could also save you from dying of a heart attack?

You probably don’t believe us, right? That’s fair, but the deadly Fraser Island (K’gari) funnel web spider, might also be the most helpful. Investigators from the University of Queensland in Australia have found a way to extract a molecule from the spider’s venom that might help stop damage from heart attacks and may even preserve hearts being used for transplants. “The Hi1a protein from spider venom blocks acid-sensing ion channels in the heart, so the death message is blocked, cell death is reduced, and we see improved heart cell survival,” Nathan Palpant, PhD, of the university, noted in a written statement.

No one has ever developed a drug to stop the “death signal,” so maybe it’s time to befriend spiders instead of running away from them in horror. Just leave the venom extraction to the professionals.

Young Black athletes who suffered concussions while playing sports were quicker to return to school and less likely to adjust their daily routines than young White athletes, according to a new study on racial differences in concussion recovery.

“The findings from this study provide novel evidence that the recovery experience following sport-related concussion likely differs between Black and White athletes, and understanding these differences may serve to provide better and more personalized intervention and management strategies,” wrote lead author Aaron M. Yengo-Kahn, MD, of Vanderbilt University Medical Center in Nashville, Tenn. The study was published in the Journal of Neurosurgery: Pediatrics.

To assess how postconcussion experiences and recovery time differ among young White and Black athletes, the researchers launched a retrospective cohort study of youths between the ages of 12 and 23 from the middle Tennessee, northern Alabama, and southern Kentucky regions who had been treated for sport-related concussion. Using data from the Vanderbilt Sports Concussion Center’s outcome registry, they examined the records of 247 student-athletes, 211 of whom were White and 36 of whom were Black.

The majority of the athletes were male – 58% of the White group and 78% of the Black group – and their average age across groups was roughly 16 years. Thirty-three percent of the Black athletes were on public insurance, compared with just 6% of the White athletes, and 41% of the Black athletes lived in low–median income areas while 55% of the White athletes lived in areas with a high median income. Approximately 90% of each group played contact sports.

The median time to symptom resolution was 21 days (interquartile range, 10.5-61.0) for White athletes but just 12.3 days (IQR, 6.8-28.0) for Black athletes. Multivariable regression confirmed that Black athletes reached asymptomatic status sooner than White athletes (hazard ratio, 1.497; 95% confidence interval, 1.014-2.209; P = .042). “The observed shorter symptom resolution among the Black athletes may be explained by a complex interplay among race, concussion knowledge, attitudes toward sport-related concussion, reporting behavior, and sociodemographic disparities,” the authors noted.

The median time until returning to school post injury was 2 school days (IQR, 0-5) for White athletes and 0 school days (IQR, 0-2) for Black athletes. After multivariable analysis, being Black was indeed associated with returning to school sooner, compared with being White (HR, 1.522; 95% CI, 1.02-2,27; P = .040). Being Black was also associated with being less likely to a report a change in daily activity post concussion (odds ratio, 0.368; 95% CI, 0.136-0.996; P = .049).
 

Adding race to research

To make headway toward understanding race’s impact on concussion research, the authors proposed three immediate steps: Work directly with schools instead of clinics or emergency departments, match the diversity of study cohorts with the racial makeup of the surrounding community, and consider race as a covariate during study design.

“In our work with concussions, there is very little reported on race or racism or how racism affects how patients are navigating these spaces,” said coauthor Jessica Wallace, PhD, of the department of health science at the University of Alabama in Tuscaloosa, Ala., in an interview. “But we have so many athletes at the youth level, adolescent level, even the collegiate level; it’s such a diverse array of patients. We need to have data representative of all of our groups so that we know where we need to be intentional about reducing disparities and closing gaps.”

Dr. Wallace, who recently authored a study on the underreporting of concussions among Black and White high school athletes, emphasized the need for concussion research to be a true collaboration across disciplines.

“I approach this work from this public health and athletic training lens, whereas a lot of my collaborators are in neurosurgery and neurology,” she said. “Moving forward, we as a scientific clinical community have to do interdisciplinary work and be very intentional about how we go about closing these gaps. We have to recognize that there are differences in knowledge and in care, and they’re unacceptable, and we have to work collaboratively in providing resources to communities equitably to decrease them.”

The authors acknowledged their study’s limitations, including the retrospective nature of the study, using zip codes to determine median household income, and an unbalanced number of White and Black athletes. They did add, however, that the ratio of participants “generally aligns with census data in the surrounding metropolitan and county areas.” That said, they also surmised that the scarcity of Black athletes could indicate a deeper disparity in health care system usage and asked future researchers to “consider enrolling athletes directly from schools rather than from within the concussion clinic only.”

Dr. Yengo-Kahn disclosed holding a compensated position on the scientific advisory board of BlinkTBI, but the authors noted that the company had no role in the study and its products were not used. No other conflicts of interest were reported.

The novel calcitonin gene-related peptide (CGRP) antagonist atogepant is safe and effective for the preventive treatment of migraine, full results from a phase 3 trial suggest.

AbbVie, the company developing the oral therapy, announced topline results of the ADVANCE trial of atogepant last year. Safety results were presented in April at the 2021 annual meeting of the American Academy of Neurology.

The full results were published online Aug. 19 in the New England Journal of Medicine ahead of the upcoming target action date of the U.S. Food and Drug Administration.

The multicenter study included nearly 900 patients who were randomly assigned to receive either placebo or one of three doses of atogepant for 12 weeks. The mean number of monthly migraine days decreased by about 4 for all three doses of the active treatment, compared with a reduction of 2.5 days with placebo.

All doses effective

The study included 873 patients with episodic migraine with or without aura. Patients who were not assigned to the placebo control group received either 10 mg, 30 mg, or 60 mg of atogepant once daily.

After a 4-week screening period, all patients received treatment for 12 weeks and then entered a 4-week safety follow-up period. In total, the participants completed eight scheduled clinical visits.

The mean reduction from baseline in the mean number of migraine days per month was 3.7 with the 10-mg dose of atogepant, 3.9 with the 30-mg dose, 4.2 with the 60-mg dose, and 2.5 with placebo. The differences between each active dose and placebo was statistically significant (P < .001).

Treatment with the CGRP inhibitor was also associated with a reduction in the mean number of headache days per month. The mean reduction from baseline was 3.9 days for the 10-mg dose, 4.0 days for the 30-mg dose, 4.2 days for the 60-mg dose, and 2.5 days for placebo (P < .001 for all comparisons with placebo).

In addition, for 55.6% of the 10-mg group, 58.7% of the 30-mg group, 60.8% of the 60-mg group, and 29.0% of the control group, there was a reduction of at least 50% in the 3-month average number of migraine days per month (P < .001 for each vs. placebo).

The most commonly reported adverse events (AEs) among patients who received atogepant were constipation (6.9%-7.7% across doses), nausea (4.4%-6.1%), and upper respiratory tract infection (1.4%-3.9%). Frequency of AEs did not differ between the active-treatment groups and the control group, and no relationships between AEs and atogepant dose were observed.
 

Multidose flexibility

“Side effects were pretty even across the board,” said Dr. Ailani. She noted that the reported AEs were expected because of atogepant’s mechanism of action. In addition, the rate of discontinuation in the study was low.

The proportion of participants who experienced a reduction in monthly migraine days of at least 50% grew as time passed. “By the end of this study, your chance of having a greater than 50% response is about 75%,” Dr. Ailani said.

“Imagine telling your patient, ‘You stick on this drug for 3 months, and I can almost guarantee you that you’re going to get better,’” she added.

Although the treatment has no drug-drug contraindications, drug-drug interactions may occur. “The availability of various doses would allow clinicians to adjust treatment to avoid potential drug-drug interactions,” said Dr. Ailani. “That multidose flexibility is very important.”

An FDA decision on atogepant could be made in the coming months. “I’m hopeful, as a clinician, that it is positive news, because we really have waited a long time for something like this,” Dr. Ailani said.

“You can easily identify patients who would do well on this medication,” she added.

In a different study of atogepant among patients with chronic migraine, there were recruitment delays because of the pandemic. That study is now almost complete, Dr. Ailani reported.
 

“Well-conducted study”

Commenting on the findings, Kathleen B. Digre, MD, chief of the division of headache and neuro-ophthalmology at the University of Utah Health, Salt Lake City, expressed enthusiasm for the experimental drug. “I’m excited to see another treatment modality for migraine,” said Dr. Digre, who was not involved with the research. “It was a very well-conducted study,” she added.

The treatment arms were almost identical in regard to disease severity, and all the doses showed an effect. Although the difference in reduction of monthly migraine days in comparison with placebo was numerically small, “for people who have frequent migraine, it’s important,” Dr. Digre said.

The results for atogepant should be viewed in a larger context, however. “Even though it’s a treatment that works better than placebo for well-matched controls, it may not be a medication that everybody’s going to respond to,” she noted. “And we can’t generalize it for some of the most disabled people, which is for chronic migraine,” she said.

It is significant that the study was published in the New England Journal of Medicine, Dr. Digre noted. “Sometimes migraine is dismissed as not important and not affecting people’s lives,” she said. “That makes me very happy to see migraine being taken seriously by our major journals.”

In addition, she noted that the prospects for FDA approval of atogepant seem favorable. “I’m hopeful that they will approve it, because it’s got a low side-effect profile, plus it’s effective.”

Migraine-specific preventive therapy has emerged only in the past few years. “I’m so excited to see this surge of preventive medicine for migraine,” Dr. Digre said. “It’s so important, because we see so many people who are disabled by migraine,” she added.

The study was funded by Allergan before atogepant was acquired by AbbVie. Dr. Ailani has received honoraria from AbbVie for consulting, has received compensation from Allergan and AbbVie for participating in a speakers’ bureau, and has received clinical trial grants from Allergan. Dr. Digre has reported no relevant financial relationships.

The novel calcitonin gene-related peptide (CGRP) antagonist atogepant is safe and effective for the preventive treatment of migraine, full results from a phase 3 trial suggest.

AbbVie, the company developing the oral therapy, announced topline results of the ADVANCE trial of atogepant last year. Safety results were presented in April at the 2021 annual meeting of the American Academy of Neurology.

The full results were published online Aug. 19 in the New England Journal of Medicine ahead of the upcoming target action date of the U.S. Food and Drug Administration.

The multicenter study included nearly 900 patients who were randomly assigned to receive either placebo or one of three doses of atogepant for 12 weeks. The mean number of monthly migraine days decreased by about 4 for all three doses of the active treatment, compared with a reduction of 2.5 days with placebo.

All doses effective

The study included 873 patients with episodic migraine with or without aura. Patients who were not assigned to the placebo control group received either 10 mg, 30 mg, or 60 mg of atogepant once daily.

After a 4-week screening period, all patients received treatment for 12 weeks and then entered a 4-week safety follow-up period. In total, the participants completed eight scheduled clinical visits.

The mean reduction from baseline in the mean number of migraine days per month was 3.7 with the 10-mg dose of atogepant, 3.9 with the 30-mg dose, 4.2 with the 60-mg dose, and 2.5 with placebo. The differences between each active dose and placebo was statistically significant (P < .001).

Treatment with the CGRP inhibitor was also associated with a reduction in the mean number of headache days per month.

In addition, for 55.6% of the 10-mg group, 58.7% of the 30-mg group, 60.8% of the 60-mg group, and 29.0% of the control group, there was a reduction of at least 50% in the 3-month average number of migraine days per month (P < .001 for each vs. placebo).

New consensus recommendations address diagnosis and management of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), with advice that may also be helpful for patients with lingering symptoms following acute COVID-19 infection.

The document was published online Aug. 25, 2021, in the Mayo Clinic Proceedings by the 23-member U.S. ME/CFS Clinician Coalition, headed by Lucinda Bateman, MD, of the Bateman Horne Center of Excellence, Salt Lake City. The document is the culmination of work that began with a summit held at the center in March 2018.

The target audience is both generalist and specialist health care providers. While ME/CFS is estimated to affect up to 2.5 million Americans, more than 90% are either undiagnosed or misdiagnosed with other conditions such as depression. And those who are diagnosed often receive inappropriate, outdated treatments such as psychotherapy and exercise prescriptions.

“Despite myalgic encephalomyelitis/chronic fatigue syndrome affecting millions of people worldwide, many clinicians lack the knowledge to appropriately diagnose or manage ME/CFS. Unfortunately, clinical guidance has been scarce, obsolete, or potentially harmful,” Dr. Bateman and colleagues wrote.

The urgency of appropriate recognition and management of ME/CFS has increased as growing numbers of people are exhibiting signs and symptoms of ME/CFS following acute COVID-19 infection. This isn’t surprising because the illness has long been linked to other infections, including Epstein-Barr virus, the authors noted.

The document covers the epidemiology, impact, and prognosis of ME/CFS, as well as etiology and pathophysiology. “Scientific studies demonstrate multiple dysfunctional organ systems, including neuro, immune, and metabolic, in ME/CFS. These findings are not explained merely by deconditioning,” document coauthor Lily Chu, MD, an independent consultant in Burlingame, Calif., said in an interview.

The document reviews the 2015 U.S. Institute of Medicine (now Academy of Medicine) diagnostic criteria that are now also recommended by the Centers for Disease Control and Prevention. They are based on four main symptoms: substantial reduction or impairment in the ability to engage in preillness levels of occupational, educational, social or personal activities for longer than 6 months; postexertional malaise, a worsening of all current symptoms, that patients often describe as a “crash”; unrefreshing sleep; and cognitive impairment and/or orthostatic intolerance.

“The new diagnostic criteria focusing on the key symptom of postexertional malaise rather than chronic fatigue, which is common in many conditions, may make the diagnostic process quicker and more accurate. Diagnosis now is both an inclusionary and not just exclusionary process, so it’s not necessary to eliminate all causes of fatigue. Diagnose patients who fit the criteria and be alert for it in people with persistent symptoms post COVID,” Dr. Chu said.

The document provides advice for taking a clinical history to obtain the information necessary for making the diagnosis, including use of laboratory testing to rule out other conditions. Physical exams, while they may not reveal specific abnormalities, may help in identifying comorbidities and ruling out alternative diagnoses.

A long list of nonpharmacologic and pharmacologic treatment and management approaches is offered for each of the individual core and common ME/CFS symptoms, including postexertional malaise, orthostatic intolerance, sleep issues, cognitive dysfunction and fatigue, immune dysfunction, pain, and gastrointestinal issues.

The document recommends against using the “outdated standard of care” cognitive-behavioral therapy and graded exercise therapy as primary treatments for the illness. Instead, the authors recommend teaching patients “pacing,” an individualized approach to energy conservation aimed at minimizing the frequency, duration, and severity of postexertional malaise.

Clinicians are also advised to assess patients’ daily living needs and provide support, including acquiring handicap placards, work or school accommodations, and disability benefits.

“There are things clinicians can do now to help patients even without a disease-modifying treatment. These are actions they are already familiar with and carry out for people with other chronic diseases, which often have limited treatment options as well. Don’t underestimate the importance and value of supportive care for patients.” Dr. Chu said.

The recommendations are based primarily on clinical expertise because there are very few randomized trials, and much of the evidence from other types of trials has been flawed, document coauthor Anthony L. Komaroff, MD, of Brigham and Women’s Hospital and Harvard Medical School, both in Boston, said in an interview.

“The sad reality is there aren’t very many large randomized clinical trials with this illness and so what a group of very experienced clinicians did was to gather their collective experience and report it as that. It’s largely uncontrolled experience, but from people who have seen a lot of patients, for what it’s worth to the medical community.”

Dr. Komaroff also advised that clinicians watch out for ME/CFS in patients with long COVID. “If we find that those called long COVID meet ME/CFS criteria, the reason for knowing that is that there are already some treatments that according to experienced clinicians are helpful for ME/CFS, and it would be perfectly appropriate to try some of them in long COVID, particularly the ones that have minimal adverse reactions.”

The guidelines project was supported by the Open Medicine Foundation. Dr. Komaroff reported receiving personal fees from Serimmune outside the submitted work. Dr. Chu has no disclosures.

Parkinson’s disease patients who develop anxiety early in their disease are at risk for reduced physical activity, which promotes further anxiety and cognitive decline, data from nearly 500 individuals show.

Anxiety occurs in 20%-60% of Parkinson’s disease (PD) patients but often goes undiagnosed, wrote Jacob D. Jones, PhD, of California State University, San Bernardino, and colleagues.

“Anxiety can attenuate motivation to engage in physical activity leading to more anxiety and other negative cognitive outcomes,” although physical activity has been shown to improve cognitive function in PD patients, they said. However, physical activity as a mediator between anxiety and cognitive function in PD has not been well studied, they noted.

In a study published in Mental Health and Physical Activity the researchers identified 487 adults with newly diagnosed PD within the past 2 years who were enrolled in the Parkinson’s Progression Markers Initiative. Participants were followed for up to 5 years and completed neuropsychological tests, tests of motor severity, and self-reports on anxiety and physical activity. Anxiety was assessed using the State-Trait Anxiety Inventory-Trait (STAI-T) subscale. Physical activity was assessed using the Physical Activity Scale for the Elderly (PASE). Motor severity was assessed using the Unified Parkinson’s Disease Rating Scale-Part III (UPDRS). The average age of the participants was 61 years, 65% were men, and 96% were White.

Using a direct-effect model, the researchers found that individuals whose anxiety increased during the study period also showed signs of cognitive decline. A significant between-person effect showed that individuals who were generally more anxious also scored lower on cognitive tests over the 5-year study period.

In a mediation model computed with structural equation modeling, physical activity mediated the link between anxiety and cognition, most notably household activity.

“There was a significant within-person association between anxiety and household activities, meaning that individuals who became more anxious over the 5-year study also became less active in the home,” reported Dr. Jones and colleagues.

However, no significant indirect effect was noted regarding the between-person findings of the impact of physical activity on anxiety and cognitive decline. Although more severe anxiety was associated with less activity, cognitive performance was not associated with either type of physical activity.

The presence of a within-person effect “suggests that reductions in physical activity, specifically within the first 5 years of disease onset, may be detrimental to mental health,” the researchers emphasized. Given that the study population was newly diagnosed with PD “it is likely the within-person terms are more sensitive to changes in anxiety, physical activity, and cognition that are more directly the result of the PD process, as opposed to lifestyle/preexisting traits,” they said.

The study findings were limited by several factors, including the use of self-reports to measure physical activity, and the lack of granular information about the details of physical activity, the researchers noted. Another limitation was the inclusion of only newly diagnosed PD patients, which might limit generalizability.

“Future research is warranted to understand if other modes, intensities, or complexities of physical activity impact individuals with PD in a different manner in relation to cognition,” they said.

Parkinson’s disease patients who develop anxiety early in their disease are at risk for reduced physical activity, which promotes further anxiety and cognitive decline, data from nearly 500 individuals show.

Anxiety occurs in 20%-60% of Parkinson’s disease (PD) patients but often goes undiagnosed, wrote Jacob D. Jones, PhD, of California State University, San Bernardino, and colleagues.

“Anxiety can attenuate motivation to engage in physical activity leading to more anxiety and other negative cognitive outcomes,” although physical activity has been shown to improve cognitive function in PD patients, they said. However, physical activity as a mediator between anxiety and cognitive function in PD has not been well studied, they noted.

In a study published in Mental Health and Physical Activity the researchers identified 487 adults with newly diagnosed PD within the past 2 years who were enrolled in the Parkinson’s Progression Markers Initiative. Participants were followed for up to 5 years and completed neuropsychological tests, tests of motor severity, and self-reports on anxiety and physical activity. Anxiety was assessed using the State-Trait Anxiety Inventory-Trait (STAI-T) subscale. Physical activity was assessed using the Physical Activity Scale for the Elderly (PASE). Motor severity was assessed using the Unified Parkinson’s Disease Rating Scale-Part III (UPDRS). The average age of the participants was 61 years, 65% were men, and 96% were White.

Using a direct-effect model, the researchers found that individuals whose anxiety increased during the study period also showed signs of cognitive decline. A significant between-person effect showed that individuals who were generally more anxious also scored lower on cognitive tests over the 5-year study period.

Obstructive sleep apnea is becoming more common in children and adolescents as the prevalence of obesity increases, but it may also be a preventable risk factor for cardiovascular disease, according to a new scientific statement from the American Heart Association.

The statement focuses on the links between OSA and CVD risk factors in children and adolescents, and reviews diagnostic strategies and treatments. The writing committee reported that 1%-6% of children and adolescents have OSA, as do up to 60% of adolescents considered obese.

The statement was created by the AHA’s Atherosclerosis, Hypertension, and Obesity in the Young subcommittee of the Council on Cardiovascular Disease in the Young and was published online in the Journal of the American Heart Association.

Carissa M. Baker-Smith, MD, chair of the writing group chair and director of pediatric preventive cardiology at Nemours Cardiac Center, Alfred I. duPont Hospital for Children, Wilmington, Del., explained the rationale for issuing the statement at this time, noting that the relationship between OSA and CVD in adults is well documented.

“There has been less focus on the importance of recognizing and treating sleep apnea in youth,” she said in an interview. “Thus, we felt that it was vitally important to get the word out to parents and to providers that paying attention to the quality and duration of your child’s sleep is vitally important to a child’s long-term heart health. Risk factors for heart disease, when present in childhood, can persist into adulthood.”
 

Clarity on polysomnography

For making the diagnosis of OSA in children, the statement provides clarity on the use of polysomnography and the role of the apnea-hypopnea index, which is lower in children with OSA than in adults. “One controversy, or at least as I saw it, was whether or not polysomnography testing is always required to make the diagnosis of OSA and before proceeding with tonsil and adenoid removal among children for whom enlarged tonsils and adenoids are present,” Dr. Baker-Smith said. “Polysomnography testing is not always needed before an ear, nose, and throat surgeon may recommend surgery.”

The statement also noted that history and physical examination may not yield enough reliable information to distinguish OSA from snoring.

In areas where sleep laboratories that work with children aren’t available, alternative tests such as daytime nap polysomnography, nocturnal oximetry, and nocturnal video recording may be used – with a caveat. “These alternative tests have weaker positive and negative predictive values when compared with polysomnography,” the writing committee noted. Home sleep apnea tests aren’t recommended in children. Questionnaires “are useful as screening, but not as diagnostic tools.”

Pediatric patients being evaluated for OSA should also be screened for hypertension and metabolic syndrome, as well as central nervous system and behavioral disorders. Diagnosing OSA in children and adolescents requires “a high index of suspicion,” the committee wrote.

Pediatricians and pediatric cardiologists should exercise that high index of suspicion when receiving referrals for cardiac evaluations for attention deficit hyperactivity disorder medication, Dr. Baker-Smith said. “Take the time to ask about a child’s sleep – snoring, apnea, etc. – especially if the child has obesity, difficulty focusing during the day, and if there is evidence of systemic hypertension or other signs of metabolic syndrome,” she said.

Risk factors for OSA in children

The statement also reviewed risk factors for OSA, among them obesity, particularly among children younger than 6 years. Other risk factors include upper and lower airway disease, hypotonia, parental history of hyperplasia of the adenoids and tonsils, craniofacial malformations, and neuromuscular disorders. However, the committee cited “limited data” to support that children with congenital heart disease may be at greater risk for OSA and sleep-disordered breathing (SDB).

Black children are at significantly greater risk, and socioeconomic factors “may be potential confounders,” the committee stated. Other risk factors include allergic rhinitis and sickle cell disease.

But the statement underscores that “obesity is the main risk factor” for OSA in children and adolescents, and that the presence of increased inflammation may explain this relationship. Steroids may alleviate these symptoms, even in nonobese children, and removal of the adenoids or tonsils is an option to reduce inflammation in children with OSA.

“Obesity is a significant risk factor for sleep disturbances and obstructive sleep apnea, and the severity of sleep apnea may be improved by weight-loss interventions, which then improves metabolic syndrome factors such as insulin sensitivity,” Dr. Baker-Smith said. “We need to increase awareness about how the rising prevalence of obesity may be impacting sleep quality in kids and recognize sleep-disordered breathing as something that could contribute to risks for hypertension and later cardiovascular disease.”

Children in whom OSA is suspected should also undergo screening for metabolic syndrome, and central nervous system and behavioral disorders.
 

Cardiovascular risks

The statement explores the connection between cardiovascular complications and SDB and OSA in depth.

“Inadequate sleep duration of < 5 hours per night in children and adolescents has been linked to an increased risk of hypertension and is also associated with an increased prevalence of obesity,” the committee wrote.

However, the statement left one question hanging: whether OSA alone or obesity cause higher BP in younger patients with OSA. But the committee concluded that BP levels increase with the severity of OSA, although the effects can vary with age. OSA in children peaks between ages 2 and 8, corresponding to the peak prevalence of hypertrophy of the tonsils and adenoids. Children aged 10-11 with more severe OSA may have BP dysregulation, while older adolescents develop higher sustained BP. Obesity may be a confounder for daytime BP elevations, while nighttime hypertension depends less on obesity and more on OSA severity.

“OSA is associated with abnormal BP in youth and, in particular, higher nighttime blood pressures and loss of the normal decline in BP that should occur during sleep,” Dr. Baker-Smith said. “Children with OSA appear to have higher BP than controls during both sleep and wake times, and BP levels increase with increasing severity of OSA.”

Nonetheless, children with OSA are at greater risk for other cardiovascular problems. Left ventricular hypertrophy may be a secondary outcome. “The presence of obstructive sleep apnea in children is associated with an 11-fold increased risk for LVH in children, a relationship not seen in the presence of primary snoring alone,” Dr. Baker-Smith said.

Individuals with cognitively stimulating jobs are at a lower risk of developing dementia than their peers with less challenging employment, new research suggests.

Results from a large, multicohort study also showed an association between cognitive stimulation and lower levels of certain plasma proteins, providing possible clues on a protective biological mechanism.

“These new findings support the hypothesis that mental stimulation in adulthood may postpone the onset of dementia,” Mika Kivimäki, PhD, professor and director of the Whitehall II Study, department of epidemiology, University College London, said in an interview.

The results were published online Aug. 19, 2021, in the BMJ.
 

‘Work fast and hard’

Researchers assessed the association between workplace cognitive stimulation and dementia incidence in seven cohorts that included almost 108,000 men and women (mean age, 44.6 years). All were free of dementia at baseline.

Participants included civil servants, public sector employees, forestry workers, and others from the general working population.

Investigators separated the participants into three categories of workplace cognitive stimulation: “high,” which referred to both high job demand and high job control; “low,” which referred to low demands and low control; and “medium,” which referred to all other combinations of job demand and job control.

“Highly cognitively stimulating jobs require you to work fast and hard, learn new things, be creative, and have a high level of skill,” said Dr. Kivimäki.

The researchers controlled for low education, hypertension, smoking, obesity, depression, physical inactivity, diabetes, low social contact, excessive alcohol consumption, and traumatic brain injury. These represent 10 of the 12 dementia risk factors named by the 2020 Lancet Commission on Dementia Prevention as having convincing evidence, Dr. Kivimäki noted.

Although the investigators had no data on the other two risk factors of hearing loss and air pollution, these are unlikely to be confounding factors, he said.

Follow-up for incident dementia varied from 13.7 to 30.1 years, depending on the cohort, and was 16.7 years in the total patient population. The mean age at dementia onset was 71.2 years.
 

Benefits across the life course

Results showed that incident dementia per 10,000 person years was 7.3 in the low–cognitive stimulation group and 4.8 in the high-stimulation group, for a difference of 2.5.

“These differences were relatively small because the incidence of dementia in this relatively young population was low,” Dr. Kivimäki said.

Compared with those with low stimulation, the adjusted hazard ratio for dementia for this with high stimulation was 0.77 (95% CI, 0.65-0.92).

The results were similar for men and women, and for those younger and older than 60 years. However, the link between workplace cognitive stimulation appeared stronger for Alzheimer’s disease than for other dementias.

There also appeared to be additive effects of higher cognitive stimulation in both childhood, as indicated by higher educational attainment, and adulthood, based on work characteristics, said Dr. Kivimäki.

“These findings support the benefits of cognitive stimulation across the life course, with education leading to higher peak cognitive performance and cognitive stimulation at work lowering age-related cognitive decline,” he added.

The findings don’t seem to be the result of workers with cognitive impairment remaining in unchallenging jobs, he noted. Separate analyses showed lower dementia incidence even when 10 years or more separated the assessment of cognitive stimulation and the dementia diagnosis.

“This suggests that the findings are unlikely to be biased due to reverse causation,” Dr. Kivimäki said.
 

Possible mechanism

Findings were similar when the researchers assessed effect from job changes. “This is probably because people in highly stimulating jobs are more likely to change to another highly stimulating job than to a low-stimulating job,” said Dr. Kivimäki. “Similarly, people with less stimulating jobs are seldom able to change to a substantially more stimulating job.”

As a dementia risk factor, low workplace stimulation is comparable with high alcohol intake and physical inactivity, but is weaker than education, diabetes, smoking, hypertension, and obesity, Dr. Kivimäki noted.

When asked about individuals with less cognitively stimulating jobs who are enormously stimulated outside work, he said that “previous large-scale studies have failed to find evidence that leisure time cognitive activity would significantly reduce risk of dementia.”

To explore potential underlying mechanisms, the investigators examined almost 5,000 plasma proteins in more than 2,200 individuals from one cohort in the Whitehall II study. They found six proteins were significantly lower among participants with high versus low cognitive stimulation.

In another analysis that included more than 13,500 participants from the Whitehall and another cohort, higher levels of three of these plasma proteins were associated with increased dementia risk – or conversely, lower protein levels with lower dementia risk.

The findings suggest a “novel plausible explanation” for the link between workplace cognitive stimulation and dementia risk, said Dr. Kivimäki.

He noted that higher levels of certain proteins prevent brain cells from forming new connections.
 

‘Some of the most compelling evidence to date’

In an accompanying editorial, Serhiy Dekhtyar, PhD, assistant professor (Docent), Aging Research Center, Karolinska Institute, Stockholm, noted that the study is “an important piece of work” and “some of the most compelling evidence to date” on the role of occupational cognitive stimulation in dementia risk.

The large-scale investigation in multiple cohorts and contexts has “advanced the field” and could help “explain previously mixed findings in the literature,” Dekhtyar said in an interview.

Importantly, the researchers provide “an indication of biological mechanisms potentially connecting work mental stimulation and dementia,” he added.

However, Dr. Dekhtyar noted that the difference of 2.5 incident cases of dementia per 10,000 person years of follow-up between the low and high mental-stimulation groups “is not especially large” – although it is comparable with other established risk factors for dementia.

He suspects the effect size would have been larger had the follow-up for dementia been longer.

Dr. Dekhtyar also raised the possibility that “innate cognition” might affect both educational and occupational attainment, and the subsequent dementia risk.

“Without taking this into account, we may inadvertently conclude that education or occupational stimulation help differentially preserve cognition into late life – when in reality, it may be initial differences in cognitive ability that are preserved throughout life,” he concluded.

Funding sources for the study included Nordic Research Programme on Health and Welfare (NordForsk), Medical Research Council, Wellcome Trust, Academy of Finland, and Helsinki Institute of Life Science. Dr. Kivimäki has received support from NordForsk, the UK Medical Research Council, the Wellcome Trust, the Academy of Finland, and the Helsinki Institute of Life Science. Dr. Dekhtyar disclosed no relevant financial relationships.

Results showed that incident dementia per 10,000 person years was 7.3 in the low–cognitive stimulation group and 4.8 in the high-stimulation group, for a difference of 2.5.

“These differences were relatively small because the incidence of dementia in this relatively young population was low,” Dr. Kivimäki said.

Compared with those with low stimulation, the adjusted hazard ratio for dementia for this with high stimulation was 0.77 (95% CI, 0.65-0.92).

The results were similar for men and women, and for those younger and older than 60 years. However, the link between workplace cognitive stimulation appeared stronger for Alzheimer’s disease than for other dementias.

There also appeared to be additive effects of higher cognitive stimulation in both childhood, as indicated by higher educational attainment, and adulthood, based on work characteristics, said Dr. Kivimäki.

“These findings support the benefits of cognitive stimulation across the life course, with education leading to higher peak cognitive performance and cognitive stimulation at work lowering age-related cognitive decline,” he added.

The findings don’t seem to be the result of workers with cognitive impairment remaining in unchallenging jobs, he noted. Separate analyses showed lower dementia incidence even when 10 years or more separated the assessment of cognitive stimulation and the dementia diagnosis.

“This suggests that the findings are unlikely to be biased due to reverse causation,” Dr. Kivimäki said.
 

Possible mechanism

Findings were similar when the researchers assessed effect from job changes. “This is probably because people in highly stimulating jobs are more likely to change to another highly stimulating job than to a low-stimulating job,” said Dr. Kivimäki. “Similarly, people with less stimulating jobs are seldom able to change to a substantially more stimulating job.”

As a dementia risk factor, low workplace stimulation is comparable with high alcohol intake and physical inactivity, but is weaker than education, diabetes, smoking, hypertension, and obesity, Dr. Kivimäki noted.

When asked about individuals with less cognitively stimulating jobs who are enormously stimulated outside work, he said that “previous large-scale studies have failed to find evidence that leisure time cognitive activity would significantly reduce risk of dementia.”

To explore potential underlying mechanisms, the investigators examined almost 5,000 plasma proteins in more than 2,200 individuals from one cohort in the Whitehall II study. They found six proteins were significantly lower among participants with high versus low cognitive stimulation.

In another analysis that included more than 13,500 participants from the Whitehall and another cohort, higher levels of three of these plasma proteins were associated with increased dementia risk – or conversely, lower protein levels with lower dementia risk.

The findings suggest a “novel plausible explanation” for the link between workplace cognitive stimulation and dementia risk, said Dr. Kivimäki.

He noted that higher levels of certain proteins prevent brain cells from forming new connections.
 

‘Some of the most compelling evidence to date’

In an accompanying editorial, Serhiy Dekhtyar, PhD, assistant professor (Docent), Aging Research Center, Karolinska Institute, Stockholm, noted that the study is “an important piece of work” and “some of the most compelling evidence to date” on the role of occupational cognitive stimulation in dementia risk.

The large-scale investigation in multiple cohorts and contexts has “advanced the field” and could help “explain previously mixed findings in the literature,” Dekhtyar said in an interview.

Importantly, the researchers provide “an indication of biological mechanisms potentially connecting work mental stimulation and dementia,” he added.

However, Dr. Dekhtyar noted that the difference of 2.5 incident cases of dementia per 10,000 person years of follow-up between the low and high mental-stimulation groups “is not especially large” – although it is comparable with other established risk factors for dementia.

He suspects the effect size would have been larger had the follow-up for dementia been longer.

Dr. Dekhtyar also raised the possibility that “innate cognition” might affect both educational and occupational attainment, and the subsequent dementia risk.

“Without taking this into account, we may inadvertently conclude that education or occupational stimulation help differentially preserve cognition into late life – when in reality, it may be initial differences in cognitive ability that are preserved throughout life,” he concluded.

Funding sources for the study included Nordic Research Programme on Health and Welfare (NordForsk), Medical Research Council, Wellcome Trust, Academy of Finland, and Helsinki Institute of Life Science. Dr. Kivimäki has received support from NordForsk, the UK Medical Research Council, the Wellcome Trust, the Academy of Finland, and the Helsinki Institute of Life Science. Dr. Dekhtyar disclosed no relevant financial relationships.

Individuals with cognitively stimulating jobs are at a lower risk of developing dementia than their peers with less challenging employment, new research suggests.

Results from a large, multicohort study also showed an association between cognitive stimulation and lower levels of certain plasma proteins, providing possible clues on a protective biological mechanism.

“These new findings support the hypothesis that mental stimulation in adulthood may postpone the onset of dementia,” Mika Kivimäki, PhD, professor and director of the Whitehall II Study, department of epidemiology, University College London, said in an interview.

The results were published online Aug. 19, 2021, in the BMJ.
 

‘Work fast and hard’

Researchers assessed the association between workplace cognitive stimulation and dementia incidence in seven cohorts that included almost 108,000 men and women (mean age, 44.6 years). All were free of dementia at baseline.

Participants included civil servants, public sector employees, forestry workers, and others from the general working population.

Investigators separated the participants into three categories of workplace cognitive stimulation: “high,” which referred to both high job demand and high job control; “low,” which referred to low demands and low control; and “medium,” which referred to all other combinations of job demand and job control.

“Highly cognitively stimulating jobs require you to work fast and hard, learn new things, be creative, and have a high level of skill,” said Dr. Kivimäki.

The researchers controlled for low education, hypertension, smoking, obesity, depression, physical inactivity, diabetes, low social contact, excessive alcohol consumption, and traumatic brain injury. These represent 10 of the 12 dementia risk factors named by the 2020 Lancet Commission on Dementia Prevention as having convincing evidence, Dr. Kivimäki noted.

Although the investigators had no data on the other two risk factors of hearing loss and air pollution, these are unlikely to be confounding factors, he said.

Follow-up for incident dementia varied from 13.7 to 30.1 years, depending on the cohort, and was 16.7 years in the total patient population. The mean age at dementia onset was 71.2 years.

Pregnant women who experience migraine with aura – and also the far more common tension-type headache – are at increased risk for giving birth to small-for-gestational-age babies, according to results from an observational study.

Migraine during pregnancy has been associated in previous studies with hypertensive pregnancy complications including preeclampsia; however, little is known about other headache types and their effects on pregnancy and birth outcomes.

For their research, published online July 20 in Cephalalgia, Isabella Neri, MD, PhD, and colleagues at Hospital Policlinico of Modena, Italy, looked at headache status for 515 consecutive pregnant women evaluated during their first trimester and followed through childbirth. 

Altogether 224 women, or 43.5% of the cohort, were diagnosed with migraine without aura (n = 72), migraine with aura (n = 27), or tension-type headache (n = 125). The authors did not report on the severity or frequency of headaches.

Women with migraine with aura and tension-type headache saw higher rates of small-for-gestational-age infants (25.9% and 10.4% of births, respectively) compared with 5.5% for women without headache. Women presenting with tension-type headache saw elevated risk for small-for-gestational-age infants (odds ratio [OR] 4.19, P = .004) as did women with migraine with aura (OR 5.37, P = .02).

Admission to neonatal intensive care was significantly higher in all the headache groups. However, the authors found no statistically significant associations between headaches and any other perinatal outcome investigated in the study, including gestational diabetes, placental abruption, gestational hypertension, and preterm delivery.

A previous study conducted by the same research group had reported a relationship between migraine and gestational hypertension. The authors cited the small sample size of the migraine groups in the current study, “the diverse features of the population,” and the popularity of low-dose aspirin administration as potentially affecting that outcome.
 

Interpret findings with caution

Asked by this news organization to comment on the research, two headache neurologists praised Dr. Neri and colleagues’ research for focusing on an understudied topic – but also said that the results would not change their practice unless replicated in larger studies.

Elizabeth W. Loder, MD, MPH, chief emeritus of the division of headache at Brigham and Women’s Faulkner Hospital in Boston, urged caution in interpreting the findings, particularly with regard to tension-type headache. “This study adds to information suggesting that pregnancy complications probably are higher in women who have migraine with aura, and there’s biological plausibility for that,” Dr. Loder said. “Having aura means you may have some vascular abnormalities and things that logically might be associated with an increased risk of small-for-gestational age infants.” But the small size of the migraine-with-aura group in this study – 27 women – and the fact that other perinatal outcomes measured in the study did not reach significance, allows for the possibility that the small-for-gestational-age findings were due to chance, Dr. Loder noted.

With tension-type headache, a biological rationale for small-for-gestational-age risk is more elusive, Dr. Loder said. “I would want to see that association replicated in another study before I thought that I needed to warn women with tension-type headache about this potential outcome. There’s lot of uncertainty here about the magnitude of the risk.”

While Dr. Neri and colleagues described the instruments used in their study to diagnose migraine and migraine with aura, they did not explain how tension-type headache was diagnosed. 

Tension-type headache, while common, is still not well characterized, Dr. Loder noted, and may represent a heterogeneous condition or the milder end of a biological continuum that includes migraine with aura. Also, the group in the study had a higher prevalence of smoking, and though the authors made statistical adjustments for smoking status, “smokers are systematically different than people who aren’t in other ways that could be associated with these outcomes,” Dr. Loder said.

While the authors of the study suggested that interventions might be indicated for women with tension-type headache in pregnancy, “showing an association doesn’t necessarily mean that intervening would make a difference” on pregnancy outcomes, Dr. Loder said.

Amaal J. Starling, MD, of the Mayo Clinic in Phoenix, Ariz., said in an interview that she, too, appreciated that this study looked at pregnancy outcomes in the setting of headache disorders. “Unfortunately even though headache disorders and especially migraine affect women so much, we still know very little about migraine in pregnancy,” she said.

Dr. Starling noted that many women with migraine are discouraged by their health care providers from becoming pregnant, because of the false belief that migraine cannot be managed in pregnancy. In her own practice, she said, she treats many patients with severe headache who become pregnant and who require pharmacological intervention during pregnancy.

This does not mean she regards headache in pregnancy as innocent. “I want patients to be on high alert for changes in headache symptoms in pregnancy. If someone has worsening of headache or migraine or aura in the setting of pregnancy, we consider that a red flag,” potentially indicating complications such as high blood pressure, gestational hypertension, or a blood clot.

Like Dr. Loder, Dr. Starling said she was not surprised by Dr. Neri and colleagues’ finding that migraine with aura might impact pregnancy outcomes. “We know that migraine with aura has a lot of vascular abnormalities that underlie the pathogenesis,” she said.

Dr. Starling found the findings related to tension-type headache less convincing, not least because the diagnostic criteria for tension-type headache was not made clear in the study. “I view this as an exploratory study that says maybe there’s a signal here. A larger epidemiological study would need to be done to confirm or refute this data,” Dr. Starling said. Until the findings can be replicated, “this study would not affect my clinical practice in any way.”

Dr. Neri and colleagues described no outside funding for their research or financial conflicts of interest. Dr. Starling has received consulting fees from pharmaceutical manufacturers but reported no disclosures relevant to the study discussed. Dr. Loder reported no financial conflicts of interest.

Spinal muscular atrophy (SMA) is a progressive, autosomal recessive neuromuscular disease caused by survival motor neuron protein deficiency. SMA has four phenotypes, characterized by varying levels of severity and age of onset. Types 1 and 2 are the most common and the most deadly, affecting children from birth to age 2 years. SMA is the leading genetic cause of infant death.

In this ReCAP, neurologist Emma Ciafaloni, MD, explains how novel gene therapies for SMA disrupt the pathophysiology of the disease. Use of these agents should be left to a specialist who has expertise in monitoring progression of SMA. Dr Ciafaloni is director of the Muscular Dystrophy Association Clinic at Strong Memorial Hospital in Rochester, New York, where she leads a multidisciplinary SMA care team that includes a pulmonologist, pediatrician, physical therapist, orthopedist, and dietitian.

She recommends that pediatricians stay abreast of their state's position on newborn screening for SMA because research shows that early diagnosis and treatment can improve outcomes, including life expectancy and quality of life.

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.
 

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.
