Neuropsychiatry affects pediatric OCD treatment
Treatment of pediatric obsessive-compulsive disorder (OCD) has evolved in recent years, with more attention given to some of the neuropsychiatric underpinnings of the condition and how they can affect treatment response.
At the Focus on Neuropsychiatry 2021 meeting, Jeffrey Strawn, MD, outlined some of the neuropsychiatry affecting disease and potential mechanisms to help control obsessions and behaviors, and how they may fit with some therapeutic regimens.
Dr. Strawn discussed the psychological construct of cognitive control, which can provide patients an “out” from the cycle of obsession/fear/worry and compulsion/avoidance. In the face of distress, compulsion and avoidance lead to relief, which reinforces the obsession/fear/worry; this in turn leads to more distress.
“We have an escape door for this circuit” in the form of cognitive control, said Dr. Strawn, who is an associate professor of pediatrics at Cincinnati Children’s Hospital Medical Center.
Cognitive control is linked to insight, which can in turn increase adaptive behaviors that help the patient resist the compulsion. Patients won’t eliminate distress, but they can be helped to make it more tolerable. Therapists can then help them move toward goal-directed thoughts and behaviors. Cognitive control is associated with several neural networks, but Dr. Strawn focused on two: the frontoparietal network, associated with top-down regulation; and the cingular-opercular network. Both of these are engaged during cognitive control processes, and play a role inhibitory control and error monitoring.
Dr. Strawn discussed a recent study that explored the neurofunctional basis of treatment. It compared the effects of a stress management therapy and cognitive-behavioral therapy (CBT) in children and adults with OCD at 6 and 12 weeks. The study found similar symptom reductions in both adults and adolescents in both intervention groups.
Before initiating treatment, the researchers conducted functional MRI scans of participants while conducting an incentive flanker task, which reveals brain activity in response to cognitive control and reward processing.
A larger therapeutic response was found in the CBT group among patients who had a larger pretreatment activation within the right temporal lobe and rostral anterior cingulate cortex during cognitive control, as well as those with more activation within the medial prefrontal, orbitofrontal, lateral prefrontal, and amygdala regions during reward processing. On the other hand, within the stress management therapy group, treatment responses were better among those who had lower pretreatment activation among overlapping regions.
“There was a difference in terms of the neurofunctional predictors of treatment response. One of the key regions is the medial prefrontal cortex as well as the rostral anterior cingulate,” said Dr. Strawn, at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.
On the neuropharmacology side, numerous medications have been approved for OCD. Dr. Strawn highlighted some studies to illustrate general OCD treatment concepts. That included the 2004 Pediatric OCD Treatment Study, which was one of the only trials to compare placebo with an SSRI, CBT, and the combination of SSRI and CBT. It showed the best results with combination therapy, and the difference appeared early in the treatment course.
That study had aggressive dosing, which led to some issues with sertraline tolerability. Dr. Strawn showed results of a study at his institution which showed that the drug levels of pediatric patients treated with sertraline depended on CYP2C19 metabolism, which affects overall exposure and peak dose concentration. In pediatric populations, some SSRIs clear more slowly and can have high peak concentrations. SSRIs have more side effects than serotonin and norepinephrine reuptake inhibitors in both anxiety disorders and OCD. A key difference between the two is that SSRI treatment is associated with greater frequency of activation, which is difficult to define, but includes restlessness and agitation and insomnia in the beginning stages of treatment.
SSRIs also lead to improvement early in the course of treatment, which was shown in a meta-analysis of nine trials. However, the same study showed that clomipramine is associated with a faster and greater magnitude of improvement, compared with SSRIs, even when the latter are dosed aggressively.
Clomipramine is a potent inhibitor of both serotonin and norepinephrine reuptake. It is recommended to monitor clomipramine levels in pediatric OCD patients, and Dr. Strawn suggested that monitoring should include both the parent drug and its primary metabolite, norclomipramine. At a given dose, there can be a great deal of variation in drug level. The clomipramine/norclomipramine ratio can provide information about the patient’s metabolic state, as well as drug adherence.
Dr. Strawn noted that peak levels occur around 1-3 hours after the dose, “and we really do want at least a 12-hour trough level.” EKGs should be performed at baseline and after any titration of clomipramine dose.
He also discussed pediatric OCD patients with OCD and tics. About one-third of Tourette syndrome patients experience OCD at some point. Tics often improve, whereas OCD more often persists. Tics that co-occur with OCD are associated with a lesser response to SSRI treatment, but not CBT treatment. Similarly, patients with hoarding tendencies are about one-third less likely to respond to SSRIs, CBT, or combination therapy.
Dr. Strawn discussed the concept of accommodation, in which family members cope with a patient’s behavior by altering routines to minimize distress and impairment. This may take the form of facilitating rituals, providing reassurance about a patient’s fears, acquiescing to demands, reducing the child’s day-to-day responsibilities, or helping the child complete tasks. Such actions are well intentioned, but they undermine cognitive control, negatively reinforce symptom engagement, and are associated with functional impairment. Reassurance is the most important behavior, occurring in more than half of patients, and it’s measurable. Parental involvement with rituals is also a concern. “This is associated with higher levels of child OCD severity, as well as parental psychopathology, and lower family cohesion. So
New developments in neurobiology and neuropsychology have changed the view of exposure. The old model emphasized the child’s fear rating as an index of corrective learning. The idea was that habituation would decrease anxiety and distress from future exposures. The new model revolves around inhibitory learning theory, which focuses on the variability of distress and aims to increase tolerance of distress. Another goal is to develop new, non-threat associations.
Finally, Dr. Strawn pointed out predictors of poor outcomes in pediatric OCD, including factors such as compulsion severity, oppositional behavior, frequent handwashing, functional impairment, lack of insight, externalizing symptoms, and possibly hoarding. Problematic family characteristics include higher levels of accommodation, parental anxiety, low family cohesion, and high levels of conflict. “The last three really represent a very concerning triad of family behaviors that may necessitate specific family work in order to facilitate the recovery of the pediatric patient,” Dr. Strawn said.
During the question-and-answer session after the talk, Dr. Strawn was asked whether there might be an inflammatory component to OCD, and whether pediatric autoimmune neuropsychiatric disorders associated with streptococcus (PANDAS) might be a prodromal condition. He noted that some studies have shown a relationship, but results have been mixed, with lots of heterogeneity within the studied populations. To be suspicious that a patient had OCD resulting from PANDAS would require a high threshold, including an acute onset of symptoms. “This is a situation also where I would tend to involve consultation with some other specialties, including neurology. And obviously there would be follow-up in terms of the general workup,” he said.
Dr. Strawn has received research funding from Allergan, Otsuka, and Myriad Genetics. He has consulted for Myriad Genetics, and is a speaker for CMEology and the Neuroscience Education Institute.

FROM FOCUS ON NEUROPSYCHIATRY 2021
Neurodegenerative nature of schizophrenia makes case for LAIs
Schizophrenia is a complex disease caused by dysfunction in specific brain regions or circuits. In fact, schizophrenia is not a single disease but several hundred different diseases, according to Henry A. Nasrallah, MD, who spoke on the topic at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
The underlying causes of schizophrenia can be either genetic or environmental, but all involve changes in brain development in the fetus or newborn. Psychosis can occur in a range of disorders, including epilepsy, Parkinson’s disease, cerebral tumors, and narcolepsy, to name just a few. Although it starts out as a neurodevelopmental disorder, schizophrenia becomes neurodegenerative after onset, with each new psychotic episode leading to further damage, said Dr. Nasrallah, professor of psychiatry, neurology, and neuroscience at the University of Cincinnati. Further damage leaves patients with greater and greater disability over time, said Dr. Nasrallah at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.
The course of illness in some ways resembles the cascading disability associated with strokes. Schizophrenia relapses lead to subcortical atrophy, ventricular enlargement, and further loss of white matter. The accumulating damage is a result of microglia activation, which leads to neuroinflammation and oxidative stress. Mitochondria may also produce insufficient amounts of the antioxidant glutathione.
“The main reason for relapse in schizophrenia is poor adherence to antipsychotic medications, due to anosognosia, memory impairment, avolition, and substance use. It is absolutely necessary to realize that, while oral antipsychotics are effective in the hospital due to enforced compliance by the nursing staff, patients should be switched to long-acting injectable antipsychotics (LAIs) upon discharge from the first episode, which astonishingly is rarely done by 99% of clinicians,” said Dr. Nasrallah in an interview.
That frequent failure leads to further neurodegeneration and increasing disability, which in turn can lead to high rates of homelessness, suicide, and as well as incarceration, because many state hospitals that used to provide medical care for relapsing individuals have been closed down. All of these consequences place great financial and emotional burdens on families and loved ones.
Reconceptualizing the illness
Dr. Nasrallah also advocated that schizophrenia should be classified as a neurologic disorder instead of a psychiatric disorder. He said that the neuropsychiatric mechanisms behind these related diseases support that classification, and neurologic disorders receive much more insurance coverage.
The neuroinflammatory mechanisms underlying schizophrenia suggest that therapies such as omega-3 fatty acids could provide benefit during the prodromal stages of illness. Antioxidants like N-acetyl cysteine could potentially be useful during psychotic episodes, since it boosts levels of glutathione to reduce damaging free radicals. Other approaches could prevent microglia activation, which appears to initiate neurodegeneration.
Another consequence of psychosis is programmed cell death, or apoptosis, in response to reduced levels of neurotropic agents. That could potentially be countered using agents to prevent apoptosis.
Dr. Nasrallah believes clinicians should not use first-generation antipsychotics such as haloperidol, because research has shown that those drugs, while effective, also destroy neurons. Second-generation antipsychotics (SGAs) are safer and avoid that neurotoxicity, and they also have a neuroprotective effect. The SGAs may owe their improved efficacy and safety to the fact that they don’t bind as strongly to dopamine receptors, and they are stronger 5-hydroxytryptamine2A antagonists, according to Dr. Nasrallah. A meta-analysis of 18 studies showed that patients on SGAs maintained gray matter volume, and may even achieve increases in the hippocampus and the prefrontal cortex.
In the Q&A session after the presentation, Dr. Nasrallah was asked whether treatment should be kept up for the rest of the patient’s life, or whether medication should be tapered – and perhaps stopped. He likened treatment of schizophrenia to diabetes or high blood pressure.
“It’s an illness. A lot of medical disorders require lifetime treatment, and there is no difference between psychiatry and the rest of medicine,” he said. “You have to continue the medication at the dose that worked in the acute episode, hopefully the lowest possible dose.”
Dr. Nasrallah did concede that it can be challenging to get patients to accept permanent treatment, and he shared his own strategy to achieve that outcome. “I don’t tell the patient, ‘You’re going to take this the rest of your life.’ It depresses them. So I say, ‘Let’s keep this on board for a year, and I’ll see you regularly, and I’ll monitor you, and we’ll see how it goes, and then we will make another decision at the end of the year.’ ”
During that year, Dr. Nasrallah educates the patient and develops a rapport. “I will show them a lot of data and information about the illness and the hazards of stopping [treatment]. And by the end of the year, most of my patients say: ‘Yeah, I agree. Let’s continue the good thing and let’s not fix something that’s not broken.’ ”
Dr. Nasrallah has consulted for Acadia, Alkermes, Allergan, Boehringer-Ingelheim, Indivior, Intra-Cellular, Janssen, Neurocrine, Otsuka, Sunovion, and Teva. He has also served on a speaker’s bureau for most of those companies, in addition to that of Noven.

The neuroinflammatory mechanisms underlying schizophrenia suggest that therapies such as omega-3 fatty acids could provide benefit during the prodromal stages of illness. Antioxidants like N-acetyl cysteine could potentially be useful during psychotic episodes, since it boosts levels of glutathione to reduce damaging free radicals. Other approaches could prevent microglia activation, which appears to initiate neurodegeneration.
Another consequence of psychosis is programmed cell death, or apoptosis, in response to reduced levels of neurotropic agents. That could potentially be countered using agents to prevent apoptosis.
Dr. Nasrallah believes clinicians should not use first-generation antipsychotics such as haloperidol, because research has shown that those drugs, while effective, also destroy neurons. Second-generation antipsychotics (SGAs) are safer and avoid that neurotoxicity, and they also have a neuroprotective effect. The SGAs may owe their improved efficacy and safety to the fact that they don’t bind as strongly to dopamine receptors, and they are stronger 5-hydroxytryptamine2A antagonists, according to Dr. Nasrallah. A meta-analysis of 18 studies showed that patients on SGAs maintained gray matter volume, and may even achieve increases in the hippocampus and the prefrontal cortex.
In the Q&A session after the presentation, Dr. Nasrallah was asked whether treatment should be kept up for the rest of the patient’s life, or whether medication should be tapered – and perhaps stopped. He likened treatment of schizophrenia to diabetes or high blood pressure.
“It’s an illness. A lot of medical disorders require lifetime treatment, and there is no difference between psychiatry and the rest of medicine,” he said. “You have to continue the medication at the dose that worked in the acute episode, hopefully the lowest possible dose.”
Dr. Nasrallah did concede that it can be challenging to get patients to accept permanent treatment, and he shared his own strategy to achieve that outcome. “I don’t tell the patient, ‘You’re going to take this the rest of your life.’ It depresses them. So I say, ‘Let’s keep this on board for a year, and I’ll see you regularly, and I’ll monitor you, and we’ll see how it goes, and then we will make another decision at the end of the year.’ ”
During that year, Dr. Nasrallah educates the patient and develops a rapport. “I will show them a lot of data and information about the illness and the hazards of stopping [treatment]. And by the end of the year, most of my patients say: ‘Yeah, I agree. Let’s continue the good thing and let’s not fix something that’s not broken.’ ”
Dr. Nasrallah has consulted for Acadia, Alkermes, Allergan, Boehringer-Ingelheim, Indivior, Intra-Cellular, Janssen, Neurocrine, Otsuka, Sunovion, and Teva. He has also served on a speaker’s bureau for most of those companies, in addition to that of Noven.
REPORTING FROM FOCUS ON NEUROPSYCHIATRY 2021
Nonmotor symptoms common in Parkinson’s
The hallmark of Parkinson’s disease is the accompanying motor symptoms, but the condition can bring other challenges. Among those are nonmotor symptoms, including depression, dementia, and even psychosis.
The culprit is Lewy bodies, which are also responsible for Lewy body dementia. “What we call Lewy body dementia and Parkinson’s disease are caused by the same pathological process – the formation of Lewy bodies in the brain,” Leslie Citrome, MD, MPH, said in an interview. Dr. Citrome discussed some of the psychiatric comorbidities associated with Parkinson’s disease at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
In fact, the association goes both ways. “Many people with Parkinson’s disease develop a dementia. Many people with Lewy body dementia develop motor symptoms that look just like Parkinson’s disease,” said Dr. Citrome, professor of psychiatry and behavioral sciences at New York Medical College, Valhalla, and president of the American Society for Clinical Psychopharmacology.
The motor symptoms of Parkinson’s disease are generally attributable to loss of striatal dopaminergic neurons, while nonmotor symptoms can be traced to loss of neurons in nondopaminergic regions. Nonmotor symptoms – often including sleep disorders, depression, cognitive changes, and psychosis – may occur before motor symptoms. Other problems may include autonomic dysfunction, such as constipation, sexual dysfunction, sweating, or urinary retention.
Patients might not be aware that nonmotor symptoms can occur with Parkinson’s disease and may not even consider mentioning mood changes or hallucinations to their neurologist. Family members may also be unaware.
Sleep problems are common in Parkinson’s disease, including rapid eye-movement sleep behavior disorders, vivid dreams, restless legs syndrome, insomnia, and daytime somnolence. Dopamine agonists may also cause unintended sleep.
Depression is extremely common, affecting up to 90% of Parkinson’s disease patients, and this may be related to dopaminergic losses. Antidepressant medications can worsen Parkinson’s disease symptoms: Tricyclic antidepressants increase risk of adverse events from anticholinergic drugs. Selective serotonin reuptake inhibitors (SSRIs) can exacerbate tremor and may increase risk of serotonin syndrome when combined with MAO‐B inhibitors.
Dr. Citrome was not aware of any antidepressant drugs that have been tested specifically in Parkinson’s disease patients, though “I’d be surprised if there wasn’t,” he said during the Q&A session. “There’s no one perfect antidepressant for people with depression associated with Parkinson’s disease. I would make sure to select one that they would tolerate and be willing to take and that doesn’t interfere with their treatment of their movement disorder, and (I would make sure) that there’s no drug-drug interaction,” he said.
This can include reduced working memory, learning, and planning, and generally does not manifest until at least 1 year after motor symptoms have begun. Rivastigmine is Food and Drug Administration–approved for treatment of cognitive impairment in Parkinson’s disease.
As many as 60% of Parkinson’s disease patients suffer from psychosis at some point, often visual hallucinations or delusions, which can include beliefs of spousal infidelity.
Many clinicians prescribe quetiapine off label, but there are not compelling data to support that it reduces intensity and frequency of hallucinations and delusions, according to Dr. Citrome. However, it is relatively easy to prescribe, requiring no preauthorizations, it is inexpensive, and it may improve sleep.
The FDA approved pimavanserin in 2016 for hallucinations and delusions in Parkinson’s disease, and it doesn’t worsen motor symptoms, Dr. Citrome said. That’s because pimavanserin is a highly selective antagonist of the 5-HT2A receptor, with no effect on dopaminergic, histaminergic, adrenergic, or muscarinic receptors.
The drug improves positive symptoms beginning at days 29 and 43, compared with placebo. An analysis by Dr. Citrome’s group found a number needed to treat (NNT) of 7 to gain a benefit over placebo if the metric is a ≥ 30% reduction in baseline symptom score. The drug had an NNT of 9 to achieve a ≥ 50% reduction, and an NNT of 5 to achieve a score of much improved or very much improved on the Clinical Global Impression–Improvement (CGI-I) scale. In general, an NNT less than 10 suggests that a drug is clinically useful.
In contrast, the number needed to harm (NNH) represents the number of patients who would need to receive a therapy to add one adverse event, compared with placebo. A number greater than 10 indicates that the therapy may be tolerable.
Using various measures, the NNH was well over 10 for pimavanserin. With respect to somnolence, the NNH over placebo was 138, and for a weight gain of 7% or more, the NNH was 594.
Overall, the study found that 4 patients would need to be treated to achieve a benefit over placebo with respect to a ≥ 3–point improvement in the Scale of Positive Symptoms–Parkinson’s Disease (SAPS-PD), while 21 would need to receive the drug to lead to one additional discontinuation because of an adverse event, compared to placebo.
When researchers compared pimavanserin to off-label use of quetiapine, olanzapine, and clozapine, they found a Cohen’s d value of 0.50, which was better than quetiapine and olanzapine, but lower than for clozapine. However, there is no requirement of blood monitoring, and clozapine can potentially worsen motor symptoms.
Dr. Citrome’s presentation should be a reminder to neurologists that psychiatric disorders are an important patient concern, said Henry A. Nasrallah, MD, professor of psychiatry, neurology, and neuroscience at the University of Cincinnati, who moderated the session.
“I think this serves as a model to recognize that many neurological disorders actually present with numerous psychiatric disorders,” Dr. Nasrallah said during the meeting, presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.

FROM FOCUS ON NEUROPSYCHIATRY 2021
Explosive aggression may be neurologic
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.
, 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.

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.

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.

REPORTING FROM FOCUS ON NEUROPSYCHIATRY 2021
Managing sleep in the elderly
Sleep problems are prevalent in older adults, and overmedication is a common cause. Insomnia is a concern, and it might not look the same in older adults as it does in younger populations, especially when neurodegenerative disorders may be present. “There’s often not only the inability to get to sleep and stay asleep in older adults but also changes in their biological rhythms, which is why treatments really need to be focused on both,” Ruth M. Benca, MD, PhD, said in an interview.
Dr. Benca spoke on the topic of insomnia in the elderly at a virtual meeting presented by Current Psychiatry and the American Academy of Clinical Psychiatrists. She is chair of psychiatry at Wake Forest Baptist Health, Winston-Salem, N.C.
Sleep issues strongly affect quality of life and health outcomes in the elderly, and there isn’t a lot of clear guidance for physicians to manage these issues. who spoke at the meeting presented by MedscapeLive. MedscapeLive and this news organization are owned by the same parent company.
Behavioral approaches are important, because quality of sleep is often affected by daytime activities, such as exercise and light exposure, according to Dr. Benca, who said that those factors can and should be addressed by behavioral interventions. Medications should be used as an adjunct to those treatments. “When we do need to use medications, we need to use ones that have been tested and found to be more helpful than harmful in older adults,” Dr. Benca said.
Many Food and Drug Administration–approved drugs should be used with caution or avoided in the elderly. The Beers criteria provide a useful list of potentially problematic drugs, and removing those drugs from consideration leaves just a few options, including the melatonin receptor agonist ramelteon, low doses of the tricyclic antidepressant doxepin, and dual orexin receptor antagonists, which are being tested in older adults, including some with dementia, Dr. Benca said.
Other drugs like benzodiazepines and related “Z” drugs can cause problems like amnesia, confusion, and psychomotor issues. “They’re advised against because there are some concerns about those side effects,” Dr. Benca said.
Sleep disturbance itself can be the result of polypharmacy. Even something as simple as a diuretic can interrupt slumber because of nocturnal bathroom visits. Antihypertensives and drugs that affect the central nervous system, including antidepressants, can affect sleep. “I’ve had patients get horrible dreams and nightmares from antihypertensive drugs. So there’s a very long laundry list of drugs that can affect sleep in a negative way,” said Dr. Benca.
Physicians have a tendency to prescribe more drugs to a patient without eliminating any, which can result in complex situations. “We see this sort of chasing the tail: You give a drug, it may have a positive effect on the primary thing you want to treat, but it has a side effect. When you give another drug to treat that side effect, it in turn has its own side effect. We keep piling on drugs,” Dr. Benca said.
“So if [a patient is] on medications for an indication, and particularly for sleep or other things, and the patient isn’t getting better, what we might want to do is slowly to withdraw things. Even for older adults who are on sleeping medications and maybe are doing better, sometimes we can decrease the dose [of the other drugs], or get them off those drugs or put them on something that might be less likely to have side effects,” Dr. Benca said.
To do that, she suggests taking a history to determine when the sleep problem began, and whether it coincided with adding or changing a medication. Another approach is to look at the list of current medications, and look for drugs that are prescribed for a problem and where the problem still persists. “You might want to take that away first, before you start adding something else,” said Dr. Benca.
Another challenge is that physicians are often unwilling to investigate sleep disorders, which are more common in older adults. Physicians can be reluctant to prescribe sleep medications, and may also be unfamiliar with behavioral interventions. “For a lot of providers, getting into sleep issues is like opening a Pandora’s Box. I think mostly physicians are taught: Don’t do this, and don’t do that. They’re not as well versed in the things that they can and should do,” said Dr. Benca.
If attempts to treat insomnia don’t succeed, or if the physician suspects a movement disorder or primary sleep disorder like sleep apnea, then the patients should be referred to a sleep specialist, according to Dr. Benca.
During the question-and-answer period following her talk, a questioner brought up the increasingly common use of cannabis to improve sleep. That can be tricky because it can be difficult to stop cannabis use, because of the rebound insomnia that may persist. She noted that there are ongoing studies on the potential impact of cannabidiol oil.
Dr. Benca was also asked about patients who take sedatives chronically and seem to be doing well. She emphasized the need for finding the lowest effective dose of a short-acting medication. “Patients should be monitored frequently, at least every 6 months. Just monitor your patient carefully.”

FROM FOCUS ON NEUROPSYCHIATRY 2021
Wisdom may counter loneliness, burnout in older adults
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.
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.
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.

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.
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.
