ADHD

When selecting pharmacotherapy for patients with bipolar disorder, clinical and prognostic correlates will ultimately influence what treatments make the most sense for a patient – but the process is a balancing act, according to Joseph F. Goldberg, MD.

“Everything we do in medicine in general, and psychiatry, and bipolar disorder in particular is a risk-benefit analysis,” Dr. Goldberg said at the virtual Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “Everything has its side effects. We’re always balancing risks and benefits.”

Patients with bipolar disorder often present with three common subtypes of the illness: Those who have associated psychosis, comorbid anxiety disorders, and comorbid ADHD. “These are three common presentations of the many, many kinds of presentations,” said Dr. Goldberg, clinical professor of psychiatry at the Icahn School of Medicine at Mount Sinai in New York.

Bipolar disorder with associated psychosis

In the case of bipolar I disorder, more than 50% of manic episodes have some element of psychosis, with as many as 10% of patients showing signs of delusions 2 years after an episode, Dr. Goldberg explained. In these patients, mania relapse is predicted by mood-incongruent psychosis – a condition usually associated with schizophrenia, he said.

“If [they] have unusual beliefs and ideas, and they’re not consistent with a particular mood state, we sometimes clinically think this sounds more like a primary psychotic process,” he said. “Maybe, but not necessarily. So just because the patient may say, ‘The FBI is after me,’ or, ‘My thoughts are being read over the Internet,’ and they don’t connect that with a grandiose theme, it doesn’t negate a diagnosis of bipolar disorder.”

Psychotic mania is also associated with comorbid anxiety disorder. About half of patients with bipolar I disorder will also experience impairments of attention, executive functioning, and verbal memory separately from ADHD. “The cognitive symptoms of bipolar disorder that are part of what’s inherited doesn’t seem to be the case, that there’s a clear greater degree of neuropsychological impairment in psychotic than nonpsychotic mania,” Dr. Goldberg said.

Lithium has a poor response in the presence of psychosis in patients with bipolar disorder but performs better when the patient receives it alongside an antipsychotic. “Lithium does have value in psychotic mania,” Dr. Goldberg said. “Psychosis would be a negative prognostic sign, and certainly an indication for including an antipsychotic.”

In contrast to lithium, divalproex has shown evidence in reducing manic and psychotic symptoms similarly to haloperidol. “Divalproex may reduce mania symptoms, whether or not it’s helping psychosis. You’d think you have to get both reduced at the same time, but actually can see that even if there’s baseline psychosis, that does not diminish the chance of seeing a reduction in core mania symptoms,” Dr. Goldberg said.

Carbamazepine may also be advantageous to use over lithium when patients present with delusions, and a combination of carbamazepine and lithium may be comparable to haloperidol in combination with lithium when treating psychotic mania. “What we do know is, at least in some studies, there may be some greater value in treating psychotic mania with carbamazepine as compared to lithium, particularly when there are delusions present, more so than hallucinations or formal thought disorder,” Dr. Goldberg said.

In patients with bipolar disorder and associated psychotic mania, clinicians should avoid dopamine agonists such as amphetamine and pramipexole, as well as ketamine. While some evidence has shown that second-generation antipsychotics work to treat bipolar depression, “there’s not really an evidence base to suggest that first-generation antipsychotics are protective against depression,” Dr. Goldberg said.
 

Bipolar disorder with anxiety

An association exists between comorbid anxiety disorders in patients with bipolar disorder and having a younger age of onset, in people who are less likely to recover from an initial mood episode, in people with poorer quality of life and role functioning, and in people who are less euthymic and more likely to attempt suicide, Dr. Goldberg said.

In addition, some patients may demonstrate symptoms of anxiety that aren’t part of the DSM-5 criteria for an anxiety disorder. Dr. Goldberg said he asks his patients to specify what they mean when they say they feel anxious.

“I always ask patients to tell me in very basic terms what [they] mean by anxiety. If they say, ‘I just I can’t sit still; I’m very fidgety,’ maybe that’s akathisia,” he said. “Or maybe if they say they’re very anxious, what they mean is they have so much energy they can’t contain it. This is mania or hypomania that they’re misconstruing as anxiety. We have to be very diligent and vigilant in clarifying the language here.”

To treat comorbid anxiety in patients with bipolar disorder, consider adjunctive olanzapine or lamotrigine, as both have evidence of anxiolytic efficacy. “Olanzapine does count as an antianxiety agent. Would you use it just as an antianxiety agent? Probably not in and of itself, but there’s other compelling reasons to use it,” he said. Before assuming you need to add another medication to address anxiety in a patient, “step back and think perhaps their anxiety symptoms will in themselves remit with olanzapine,” he said. Olanzapine can also be potentially used in cases where a patient has mania and anxiety to treat both conditions, he added.

Divalproex is another option for patients that has anxiolytic efficacy. “In the context of bipolar depression, divalproex does have antianxiety properties,” Dr. Goldberg said. Other anxiolytic options include lurasidone, cariprazine, quetiapine, and combination olanzapine–fluoxetine.
 

Bipolar disorder and ADHD

Among patients with bipolar disorder and comorbid adult ADHD, cognitive dysfunction inherent to bipolar disorder may be difficult to distinguish from signs of ADHD, Dr. Goldberg explained, with about 20% of people with bipolar I disorder and about 30% of people with bipolar II disorder have deficits of attentional processing, verbal memory, and executive functioning.

“Some researchers are very intrigued by the notion that cognitive problems and attentional problems aren’t necessarily a sign of [ADHD] comorbidities. They might be, but they may just be part of the endophenotype or the non-overt, genetically driven phenomenology that makes bipolar disorder so heterogeneous,” he said.

Patients with bipolar disorder and comorbid ADHD are more likely to have mania than depression, the condition is more common in men, and these patients are more likely to have substance use problems, increased risk of suicide attempts, problems in school, lower socioeconomic status, greater unemployment history, higher divorce rates, and low family history of bipolar disorder. Clinicians should check a patient’s history if they suspect comorbid adult ADHD in their patients with bipolar disorder, as there is a good chance evidence of ADHD will be present around the time of adolescence.

“You don’t wake up with [ADHD] at age 40, at least that’s not the prevailing perspective,” Dr. Goldberg said.

Focus on the ADHD symptoms that do not overlap with bipolar disorder, such as nondiscrete, chronic symptoms; lack of psychosis and suicidality; no evidence of grandiose beliefs; lack of hypersexuality; and depression that is not prominent. “You really need to go back in time and get some clarity as to the longitudinal course. If this was present earlier on and it persists into adulthood and it’s not better accounted for by either what we think of as the cognitive pervasive problems that emerge in bipolar disorder, or in relatives as a collaborator for attentional problems and bipolar disorder, we can then contemplate [whether] there’s a plausible basis for using a stimulant or [other ADHD] treatment,” he said.

In patients who are found to have adult comorbid ADHD and are nonmanic and nonpsychotic, stimulants do have an effect. Studies suggest that amphetamines such as adjunctive lisdexamfetamine added to a mood stabilizer show an improvement in ADHD symptoms after 4 weeks (Hum Psychopharmacol. 2013; 28[5]:421-7).

Adjunctive methylphenidate added to a mood stabilizer has also shown evidence of not causing treatment-emergent mania. “If you’re going to use methylphenidate, make sure it’s in the context of an antimanic mood stabilizer,” Dr. Goldberg said. In one study, methylphenidate without a mood stabilizer caused an increase in manic episodes within 3 months (Am J Psychiatry. 2017 Apr 1;174:341-8).

“All may pose safe and effective evidence-based, albeit provisional, but evidence-based options to consider in targeting the attentional symptoms in patients with bipolar disorder,” Dr. Goldberg said.

Clinicians have numerous pharmacotherapy options available to treat ADHD in their toolbox. How do you know which formulation or combination of therapies is right for your patient with ADHD?

According to Jeffrey R. Strawn, MD, the answer depends on onset and duration of the medication and how that fits in to the patient’s current needs.

The most common treatment for ADHD, stimulants, are amphetamine-based and methylphenidate-based compounds known for improving core symptoms of inattention, impulsivity, and hyperactivity and are “probably associated with the most efficacy relative to the other interventions,” Dr. Strawn, associate professor of psychiatry, pediatrics, and clinical pharmacology at Cincinnati Children’s Hospital Medical Center, said at Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “But what I think is also really important for us to remember as clinicians is that they improve adherence, social interactions, [and] academic efficiency as well as accuracy.”

Other ADHD pharmacotherapy options include nonstimulant norepinephrine reuptake inhibitors (NRIs) like atomoxetine, and alpha-2 agonists like the extended-release forms of guanfacine and clonidine. All are Food and Drug Administration–approved for the treatment of ADHD, and the FDA has approved some combination alpha-2 agonists and stimulants treatments for ADHD as well.

When making decisions about formulations for ADHD pharmacotherapy, clinicians should think about whether the patient has issues swallowing tablets or capsules. Tablets, capsules, and chewable tablets may be appropriate for patients who can easily take these medications, while patients who have problems with swallowing pills may benefit from dissolvable tablets, solutions, and transdermal applications. Each of these options “have differences in terms of absorption, also differences in terms of intestinal transit time in younger children, as well as patients perhaps with irritable bowel, as well as other conditions that may affect absorption,” Dr. Strawn said. Different formulations have unique considerations: liquid formulations have the benefit of making precise adjustments, sublingual formulations may have quick absorption and onset, and oral dissolvable tablets can improve treatment adherence and reduce misuse of medication.

Formulations can be available as a delayed release, extended release, pulsatile release, targeted release, or a combination of immediate, delayed, and/or extended release. “Ultimately, what this gives rise to is differences in onset of action and duration, as well as differences in the elimination profile of the medication,” he said.

Transdermal formulations “avoid the first-pass metabolism, which may reduce side effects or increase efficacy,” but patients converting from an oral formulation may require reducing the dose. “It’s always important to remember, for example, with something like Daytrana, the transdermal methylphenidate formulation, if we’re converting a patient from an oral methylphenidate, we roughly need to use half the dose for the transdermal formulation,” Dr. Strawn explained. Transdermal formulations can carry benefits of steady plasma concentrations and longer duration of action but may cause skin irritation or accidentally be removed. “It’s really important they’re properly disposed of because oftentimes they do contain some active medication within the residual matrix.”
 

Methylphenidate, mixed amphetamine salt–based preparations

Modified-release formulations include matrix- or reservoir-based formulations and are most importantly differentiated from other formulations by their gastrointestinal (GI) transit time and the permeation through the GI membrane. When considering what formulation to choose, “it’s important to consider that, even with an ‘extended release formulation,’ all of these medications have some percentage that is immediately released, and that percentage varies considerably from formulation to formulation,” Dr. Strawn said.

He noted that brand names are sometimes used for formulations “because it’s often very difficult for us as clinicians and even for pharmacists to distinguish between these various formulations of the medication, which often have the same ‘extended’ or ‘delayed release’ modifying term within the name of the medication.”

Examples of medications that have greater immediate release include Metadate CD (30%), Aptensio XR (37%), long-acting methylphenidate (50%), dexmethylphenidate extended-release (50%), and Mixed Salts amphetamine extended release (50%). Formulations with a less immediate release include Quillivant solution or Quillichew chewable tablets (20%), Dyanaval XR solution (20%), OROS methylphenidate (22%), Daytrana that begins within 1 or 2 hours and lasts for 9 hours, or lisdexamfetamine that begins within 1 hour and lasts for 9 hours.

Depending on a patient’s needs, one particular formulation may work better than another. Dexmethylphenidate (Focalin XR) has a 50% immediate release and 50% extended release formulation, which “may be really important for a high school student who has first period precalculus followed by second period human geography,” Dr. Strawn said, while “a patient who may have first period study hall and second period art” may benefit from OROS methylphenidate.

Clinicians should also consider the effect of counterclockwise hysteresis when adding a short-acting stimulant later in the day. “There seems to be something really magic about having that ascending concentration time curve that, when we’re on the descending loop of that concentration time curve, we really seem to get a dramatic waning of the effect of the medication, even though technically the concentration is within the ‘therapeutic range,’ ” Dr. Strawn said. “With counterclockwise hysteresis, we see that the effect increases with time for a given concentration of the medication.”
 

Combining ADHD pharmacotherapies

For children and adolescents with ADHD, atomoxetine is a nonstimulant, FDA-approved treatment option. “It seems to be effective not just in terms of total ADHD symptoms, but also in terms of hyperactive and impulsive symptoms as well as the inattentive symptoms,” Dr. Strawn said.

Pharmacogenetics can be a guide for selecting an atomoxetine for a patient with ADHD, he noted. “What I think is most relevant here is the way in which pharmacogenetics can actually help guide our dosing, which then optimizes tolerability, potentially efficacy of atomoxetine,” he said. “Atomoxetine is pretty extensively metabolized by [CYP]2D6, and it’s one of about 300 medications that actually has specific labeling from the FDA on dosing based on genotype. It recommends a slower titration, as well as a lower target dose of atomoxetine in individuals who are P450 2D6 poor metabolizers relative to those patients who are ultra-rapid or normal metabolizers.”

Atomoxetine is most often combined with methylphenidate and has some evidence of benefit in children or adolescents who do not have an adequate response to stimulants alone. When combining stimulants with the alpha-2 agonists guanfacine or clonidine, “there are some improvements in terms of the combination treatment relative to the monotherapy,” Dr. Strawn said. He also emphasized that patients taking guanfacine immediate release tend to have better absorption and faster onset, compared with the extended release formulation. “This is something that potentially is very important when we think beyond steady state and we think about the practical use of this medication,” he said.
 

Baseline history is important

Overall, taking a baseline history of a patient with ADHD is “critically important” before starting them on stimulants, Dr. Strawn said. “Specifically, I would recommend documenting a negative history of syncope, family history of sudden cardiac death, as well as the lack of any known history of structural cardiac abnormalities,” he said. “Without a consultation with the cardiologist specifically around this question, I’m very, very, very hesitant – as in I don’t – use stimulants in patients who have histories of aortic stenosis, Wolff-Parkinson-White, as well as arrhythmogenic right ventricular dysplasia.”

Although patients with ADHD were typically followed with routine hemodynamic monitoring every 3 months prior to the COVID-19 pandemic, some clinicians see their patients with ADHD less frequently if they have been stabilized on a stimulant. “It is important to check not just with the patient, but also with parents and teachers as we’re adjusting medication dose and trying to optimize the treatment regimen, particularly in young children. In adults, it may also be very helpful to talk with spouses,” Dr. Strawn said.

Dr. Strawn also called attention to a recommendation to perform a routine electrocardiogram (EKG) in patients with ADHD who might receive stimulants. “At present, there is no recommendation to obtain a routine screening EKG in these patients, provided that we have an absence of those other red flags on the history,” he said. “Certainly, I would consider it in situations where I do have persistent tachycardia or hypertension, or there are other treatment-emergent symptoms, although really in many of these situations, I’m actually speaking on the phone with my pediatric or adult cardiology colleagues.”

The most common treatment for ADHD, stimulants, are amphetamine-based and methylphenidate-based compounds known for improving core symptoms of inattention, impulsivity, and hyperactivity and are “probably associated with the most efficacy relative to the other interventions,” Dr. Strawn, associate professor of psychiatry, pediatrics, and clinical pharmacology at Cincinnati Children’s Hospital Medical Center, said at Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “But what I think is also really important for us to remember as clinicians is that they improve adherence, social interactions, [and] academic efficiency as well as accuracy.”

Other ADHD pharmacotherapy options include nonstimulant norepinephrine reuptake inhibitors (NRIs) like atomoxetine, and alpha-2 agonists like the extended-release forms of guanfacine and clonidine. All are Food and Drug Administration–approved for the treatment of ADHD, and the FDA has approved some combination alpha-2 agonists and stimulants treatments for ADHD as well.

When making decisions about formulations for ADHD pharmacotherapy, clinicians should think about whether the patient has issues swallowing tablets or capsules. Tablets, capsules, and chewable tablets may be appropriate for patients who can easily take these medications, while patients who have problems with swallowing pills may benefit from dissolvable tablets, solutions, and transdermal applications. Each of these options “have differences in terms of absorption, also differences in terms of intestinal transit time in younger children, as well as patients perhaps with irritable bowel, as well as other conditions that may affect absorption,” Dr. Strawn said. Different formulations have unique considerations: liquid formulations have the benefit of making precise adjustments, sublingual formulations may have quick absorption and onset, and oral dissolvable tablets can improve treatment adherence and reduce misuse of medication.

Formulations can be available as a delayed release, extended release, pulsatile release, targeted release, or a combination of immediate, delayed, and/or extended release. “Ultimately, what this gives rise to is differences in onset of action and duration, as well as differences in the elimination profile of the medication,” he said.

Transdermal formulations “avoid the first-pass metabolism, which may reduce side effects or increase efficacy,” but patients converting from an oral formulation may require reducing the dose. “It’s always important to remember, for example, with something like Daytrana, the transdermal methylphenidate formulation, if we’re converting a patient from an oral methylphenidate, we roughly need to use half the dose for the transdermal formulation,” Dr. Strawn explained. Transdermal formulations can carry benefits of steady plasma concentrations and longer duration of action but may cause skin irritation or accidentally be removed. “It’s really important they’re properly disposed of because oftentimes they do contain some active medication within the residual matrix.”
 

Methylphenidate, mixed amphetamine salt–based preparations

Modified-release formulations include matrix- or reservoir-based formulations and are most importantly differentiated from other formulations by their gastrointestinal (GI) transit time and the permeation through the GI membrane. When considering what formulation to choose, “it’s important to consider that, even with an ‘extended release formulation,’ all of these medications have some percentage that is immediately released, and that percentage varies considerably from formulation to formulation,” Dr. Strawn said.

He noted that brand names are sometimes used for formulations “because it’s often very difficult for us as clinicians and even for pharmacists to distinguish between these various formulations of the medication, which often have the same ‘extended’ or ‘delayed release’ modifying term within the name of the medication.”

Examples of medications that have greater immediate release include Metadate CD (30%), Aptensio XR (37%), long-acting methylphenidate (50%), dexmethylphenidate extended-release (50%), and Mixed Salts amphetamine extended release (50%). Formulations with a less immediate release include Quillivant solution or Quillichew chewable tablets (20%), Dyanaval XR solution (20%), OROS methylphenidate (22%), Daytrana that begins within 1 or 2 hours and lasts for 9 hours, or lisdexamfetamine that begins within 1 hour and lasts for 9 hours.

Depending on a patient’s needs, one particular formulation may work better than another. Dexmethylphenidate (Focalin XR) has a 50% immediate release and 50% extended release formulation, which “may be really important for a high school student who has first period precalculus followed by second period human geography,” Dr. Strawn said, while “a patient who may have first period study hall and second period art” may benefit from OROS methylphenidate.

Clinicians should also consider the effect of counterclockwise hysteresis when adding a short-acting stimulant later in the day. “There seems to be something really magic about having that ascending concentration time curve that, when we’re on the descending loop of that concentration time curve, we really seem to get a dramatic waning of the effect of the medication, even though technically the concentration is within the ‘therapeutic range,’ ” Dr. Strawn said. “With counterclockwise hysteresis, we see that the effect increases with time for a given concentration of the medication.”
 

Combining ADHD pharmacotherapies

For children and adolescents with ADHD, atomoxetine is a nonstimulant, FDA-approved treatment option. “It seems to be effective not just in terms of total ADHD symptoms, but also in terms of hyperactive and impulsive symptoms as well as the inattentive symptoms,” Dr. Strawn said.

Pharmacogenetics can be a guide for selecting an atomoxetine for a patient with ADHD, he noted. “What I think is most relevant here is the way in which pharmacogenetics can actually help guide our dosing, which then optimizes tolerability, potentially efficacy of atomoxetine,” he said. “Atomoxetine is pretty extensively metabolized by [CYP]2D6, and it’s one of about 300 medications that actually has specific labeling from the FDA on dosing based on genotype. It recommends a slower titration, as well as a lower target dose of atomoxetine in individuals who are P450 2D6 poor metabolizers relative to those patients who are ultra-rapid or normal metabolizers.”

Atomoxetine is most often combined with methylphenidate and has some evidence of benefit in children or adolescents who do not have an adequate response to stimulants alone. When combining stimulants with the alpha-2 agonists guanfacine or clonidine, “there are some improvements in terms of the combination treatment relative to the monotherapy,” Dr. Strawn said. He also emphasized that patients taking guanfacine immediate release tend to have better absorption and faster onset, compared with the extended release formulation. “This is something that potentially is very important when we think beyond steady state and we think about the practical use of this medication,” he said.
 

Baseline history is important

Overall, taking a baseline history of a patient with ADHD is “critically important” before starting them on stimulants, Dr. Strawn said. “Specifically, I would recommend documenting a negative history of syncope, family history of sudden cardiac death, as well as the lack of any known history of structural cardiac abnormalities,” he said. “Without a consultation with the cardiologist specifically around this question, I’m very, very, very hesitant – as in I don’t – use stimulants in patients who have histories of aortic stenosis, Wolff-Parkinson-White, as well as arrhythmogenic right ventricular dysplasia.”

Although patients with ADHD were typically followed with routine hemodynamic monitoring every 3 months prior to the COVID-19 pandemic, some clinicians see their patients with ADHD less frequently if they have been stabilized on a stimulant. “It is important to check not just with the patient, but also with parents and teachers as we’re adjusting medication dose and trying to optimize the treatment regimen, particularly in young children. In adults, it may also be very helpful to talk with spouses,” Dr. Strawn said.

Dr. Strawn also called attention to a recommendation to perform a routine electrocardiogram (EKG) in patients with ADHD who might receive stimulants. “At present, there is no recommendation to obtain a routine screening EKG in these patients, provided that we have an absence of those other red flags on the history,” he said. “Certainly, I would consider it in situations where I do have persistent tachycardia or hypertension, or there are other treatment-emergent symptoms, although really in many of these situations, I’m actually speaking on the phone with my pediatric or adult cardiology colleagues.”

Irritability appears to be a potent independent predictor of increased risk for suicidality in children and adolescents with ADHD, Tomer Levy, MD, said at the virtual congress of the European College of Neuropsychopharmacology.

While there is ample evidence that ADHD is associated with increased suicidality, Dr. Levy’s recent study involving 1,516 youths aged 6-17 years attending an outpatient ADHD clinic demonstrated that this increased risk is mediated by depression and irritability in roughly equal measures. Moreover, upon controlling for those two factors in a multivariate analysis, ADHD symptoms, per se, had no direct effect on risk of suicidality as defined by suidical ideation, attempts, or self-harm.

The clinical take-home message is that assessing irritability, as well as depression, may bolster an estimate of suicidality and help in managing suicidal risk in ADHD, according to Dr. Levy, a child and adolescent psychiatrist at the Hospital for Sick Children, Toronto, and head of behavioral regulation services at the Geha Mental Health Center in Petah Tikva, Israel.

The study included separate parent- and teacher-structured reports of the youths’ ADHD symptoms, suicidality, depression, irritability, and anxiety. Parents reported suicidality in 12.1% of the pediatric patients, significantly higher than the 3.8% rate reported by teachers.

In multivariate analyses, parent-reported depression accounted for 39.1% of the association between ADHD symptoms and suicidality, while irritability symptoms mediated 36.8% of the total effect. In the teachers’ reports, depression and irritability symptoms accounted for 45.3% and 38.4% of the association. Anxiety symptoms mediated 19% of the relationship between ADHD and suicidality by parental report but had no significant impact on the association according to teacher report in the recently published study.

Dr. Levy noted that, in the DSM-5, irritability cuts across diagnostic categories. It is not only a core dimension of ADHD, but of the other externalizing disorders – conduct disorder and oppositional defiant disorder – as well, and also of neurodevelopmental, internalizing, and stress-related disorders.

Interventional studies aimed at dampening irritability as a potential strategy to reduce suicidality haven’t yet been done, but they deserve research priority status, in Dr. Levy’s view. Numerous functional dimensions that influence irritability are potential targets, including aggression, negative affect, low tolerance of frustration, skewed threat perception, and impaired self-regulation, according to the psychiatrist.

Most suicidal youths are attempting to cope with mental disorders. The most prevalent of these are major depressive disorder and dysthymia, followed by externalizing disorders. And among the externalizing disorders, conduct disorder stands out in terms of the magnitude of associated suicidality risk. In a large Taiwanese national study including 3,711 adolescents with conduct disorder and 14,844 age- and sex-matched controls, conduct disorder was associated with an adjusted 5.17-fold increased risk of subsequent suicide attempts over the next 10 years in a multivariate regression analysis adjusted for other psychiatric comorbidities and demographics.

In addition to depression, irritability symptoms, and conduct problems, other risk factors that should be part of a suicidality assessment in children and adolescents with ADHD include substance use, anxiety, poor family support, and bullying and/or being bullied. But, perhaps surprisingly, not impulsivity, Dr. Levy said.

“There is a widely held perception that impulsivity imparts a risk for suicidality, and especially in the transition from ideation to attempt. However, more recent evidence fails to show a convincing association,” according to Dr. Levy.

He reported having no financial conflicts regarding his presentation.

Microdosing with lysergic acid diethylamide (LSD) is associated with improved mood and increased attention, early research suggests. However, at least one expert believes it’s far too soon to tell and warns against endorsing patient microdosing.

In a dose-finding exploratory study, three low doses of LSD were compared with placebo in healthy volunteers who were all recreational drug users. Adjusted results showed that the highest dose boosted attention and mood, although participants were aware of psychedelic effects, prompting researchers to conclude the results demonstrated “selective, beneficial effects.”

“The majority of participants have improved attention,” study investigator Nadia Hutten, PhD, Department of Neuropsychology and Psychopharmacology, Maastricht University, the Netherlands, told Medscape Medical News.

“So we think that patients with attention deficits might have more beneficial effects,” she added, noting her team plans to study LSD microdosing in patients with attention deficit hyperactivity disorder.

The study was presented at the 33rd European College of Neuropsychopharmacology (ECNP) Congress, which was held online this year because of the COVID-19 pandemic.

Growing interest

Over the past 10 years there has been growing interest in psychedelic microdosing, which is defined as a dose that aims to enhance mood and/or performance but does not affect perception.

However, there has been considerable debate over what constitutes a “microdose.” One tenth of a “full” psychedelic dose is typically suggested, but users report a much wider dose range in practice, suggesting potential “individual variation in response to low doses,” the researchers note.

In the current dose-finding study, the researchers explored whether the effects of LSD on cognition and subjective measures differed between individuals.

The study included 24 healthy recreational drug users and compared the acute effects of 5 mcg, 20 mcg, and 20 mcg LSD with placebo on a computer-based psychomotor vigilance task (PVT) that measured attention and on a Digit Symbol Substitution Test (DSST).

Participants also completed the 72-item Profile of Mood States (POMS) questionnaire, a visual analog scale (VAS) on mood, and the 94-item 5-Dimensional Altered States of Consciousness Rating scales (5D-ASC).

Unadjusted results showed that the 20-mcg LSD dose significantly reduced correct substitutions on the DSST vs placebo (P < .05), but had no effect on attentional lapses on the PCT or on positive mood on the POMS.

Correcting the DSST score for the number of total responses revealed no dose effect of LSD. This suggested that participants were no less accurate when under the influence of LSD, even though they encoded fewer digits, the researchers note.

Participants also reported that both the 10-mcg and 20-mcg dose of LSD increased subjective experiences on the VAS and alternated states of consciousness on the 5D-ASC compared with placebo.

After stratifying the results by dose and participant, the effect of LSD differed between individuals. For example, both the 5-mcg and 20-mcg doses were associated with improvement in attention on the PVT (P < .05), but not the 10-mcg dose.

These results also indicated that the 20-mcg dose was associated with a significant increase in the correct number of substitutions on the DSST and with a significant increase in positive mood on the POMS (P < .05 for both outcomes).

The findings suggest that future studies in patient populations with impaired attention are needed, “including biological parameters involved in LSD receptor-binding and metabolism, in order to understand the inter-individual variation in response to LSD,” the investigators note.

In an educational session at the meeting, the study’s lead researcher, Kim Kuypers, PhD, associate professor at Maastricht University, said research shows individuals are already self-medicating with psychedelic microdosing to treat a wide range of mental health problems, and rated it as significantly more effective than conventional therapy at alleviating symptoms and improving quality of life.

Nevertheless, Kuypers noted there have been fewer than 20 published placebo-controlled studies examining psychedelic microdosing in humans – and much of the current evidence is anecdotal.

However, there is some clinical research suggesting that low-dose LSD is associated with improved mood and cognitive performance and that it also has an effect on resting-state amygdala functional connectivity and acutely increases brain-derived neurotrophic factor plasma levels.

Furthermore, said Kuypers, the evidence in healthy volunteers thus far suggests microdosing is “safe.”
 

Jumping ahead of the science?

Commenting on the study for Medscape Medical News, Jeffrey A. Lieberman, MD, professor and chair of psychiatry at Columbia University, New York City, said he “gives the investigators credit for doing such a study” but does not believe anything can be gleaned from the findings.

He said he is also concerned that the resurgence of psychedelic research is not congruent with “the methodologic rigor and scientific thinking that accompanies treatment development in other disease areas.”

Lieberman, who is also psychiatrist-in-chief at the NewYork–Presbyterian Hospital Columbia Medical Center and was not involved with the study, added that some of the research is also being conducted in individuals who are “true believers and not sufficiently dispassionate and objective.”

“If this was just a treatment . . . for some type of skin fungus, no one would pay any attention to it. But because these are such notorious and interesting compounds, they have attracted a lot of peripheral interest to promote and to disseminate; and the risk is that it will be done in the wrong way and there may be consequences,” he said.

Moreover, Lieberman noted that the psychedelic drugs may be used in practice ahead of strong evidence of safety and efficacy. As an example, he pointed to ketamine, a drug that was identified as a treatment for people with depression who had not responded to standard treatments, he noted.

“But before you knew it, there were clinics being opened up all over the place by anesthesiologists or other people that were trying to make a quick buck,” he said.

“That was alarming because they were stretching the criteria for whom the treatment was appropriate; there were no protocols for dosing, for frequency of administration, and there was inadequate psychiatric follow-up,” Lieberman added.
 

Preliminary but promising

He agreed with Kuypers that cases of microdosing with psychedelics are largely anecdotal.

“So in that context, when these investigators tried to put it to a test, which is commendable, the results in no way tell you whether it’s good, bad, or indifferent,” Lieberman said. In fact, the results are “disappointing in terms of suggesting any beneficial effect.”

Lieberman said more and larger studies are needed in order to determine whether LSD microdosing is beneficial. 

In response to Lieberman’s comments, Kuypers told Medscape Medical News that the investigators tried to base their placebo-controlled research on previous anecdotal research.

She emphasized that the “whole field is still in its infancy,” including research on the use of “full” doses of psychedelics.

“I sometimes think that the message is too positive. We should never forget to communicate that not a lot of research has been done.” In addition, she agreed that researchers should “keep a balanced message.”

“All the data to date is preliminary, in my view, but promising,” she stressed, “and the evidence is growing.”

Microdosing with lysergic acid diethylamide (LSD) is associated with improved mood and increased attention, early research suggests. However, at least one expert believes it’s far too soon to tell and warns against endorsing patient microdosing.

In a dose-finding exploratory study, three low doses of LSD were compared with placebo in healthy volunteers who were all recreational drug users. Adjusted results showed that the highest dose boosted attention and mood, although participants were aware of psychedelic effects, prompting researchers to conclude the results demonstrated “selective, beneficial effects.”

“The majority of participants have improved attention,” study investigator Nadia Hutten, PhD, Department of Neuropsychology and Psychopharmacology, Maastricht University, the Netherlands, told Medscape Medical News.

“So we think that patients with attention deficits might have more beneficial effects,” she added, noting her team plans to study LSD microdosing in patients with attention deficit hyperactivity disorder.

The study was presented at the 33rd European College of Neuropsychopharmacology (ECNP) Congress, which was held online this year because of the COVID-19 pandemic.

Growing interest

Over the past 10 years there has been growing interest in psychedelic microdosing, which is defined as a dose that aims to enhance mood and/or performance but does not affect perception.

However, there has been considerable debate over what constitutes a “microdose.” One tenth of a “full” psychedelic dose is typically suggested, but users report a much wider dose range in practice, suggesting potential “individual variation in response to low doses,” the researchers note.

In the current dose-finding study, the researchers explored whether the effects of LSD on cognition and subjective measures differed between individuals.

The study included 24 healthy recreational drug users and compared the acute effects of 5 mcg, 20 mcg, and 20 mcg LSD with placebo on a computer-based psychomotor vigilance task (PVT) that measured attention and on a Digit Symbol Substitution Test (DSST).

Participants also completed the 72-item Profile of Mood States (POMS) questionnaire, a visual analog scale (VAS) on mood, and the 94-item 5-Dimensional Altered States of Consciousness Rating scales (5D-ASC).

Unadjusted results showed that the 20-mcg LSD dose significantly reduced correct substitutions on the DSST vs placebo (P < .05), but had no effect on attentional lapses on the PCT or on positive mood on the POMS.

Correcting the DSST score for the number of total responses revealed no dose effect of LSD. This suggested that participants were no less accurate when under the influence of LSD, even though they encoded fewer digits, the researchers note.

Participants also reported that both the 10-mcg and 20-mcg dose of LSD increased subjective experiences on the VAS and alternated states of consciousness on the 5D-ASC compared with placebo.

After stratifying the results by dose and participant, the effect of LSD differed between individuals. For example, both the 5-mcg and 20-mcg doses were associated with improvement in attention on the PVT (P < .05), but not the 10-mcg dose.

These results also indicated that the 20-mcg dose was associated with a significant increase in the correct number of substitutions on the DSST and with a significant increase in positive mood on the POMS (P < .05 for both outcomes).

The findings suggest that future studies in patient populations with impaired attention are needed, “including biological parameters involved in LSD receptor-binding and metabolism, in order to understand the inter-individual variation in response to LSD,” the investigators note.

In an educational session at the meeting, the study’s lead researcher, Kim Kuypers, PhD, associate professor at Maastricht University, said research shows individuals are already self-medicating with psychedelic microdosing to treat a wide range of mental health problems, and rated it as significantly more effective than conventional therapy at alleviating symptoms and improving quality of life.

Nevertheless, Kuypers noted there have been fewer than 20 published placebo-controlled studies examining psychedelic microdosing in humans – and much of the current evidence is anecdotal.

However, there is some clinical research suggesting that low-dose LSD is associated with improved mood and cognitive performance and that it also has an effect on resting-state amygdala functional connectivity and acutely increases brain-derived neurotrophic factor plasma levels.

Furthermore, said Kuypers, the evidence in healthy volunteers thus far suggests microdosing is “safe.”
 

Jumping ahead of the science?

Commenting on the study for Medscape Medical News, Jeffrey A. Lieberman, MD, professor and chair of psychiatry at Columbia University, New York City, said he “gives the investigators credit for doing such a study” but does not believe anything can be gleaned from the findings.

He said he is also concerned that the resurgence of psychedelic research is not congruent with “the methodologic rigor and scientific thinking that accompanies treatment development in other disease areas.”

Lieberman, who is also psychiatrist-in-chief at the NewYork–Presbyterian Hospital Columbia Medical Center and was not involved with the study, added that some of the research is also being conducted in individuals who are “true believers and not sufficiently dispassionate and objective.”

“If this was just a treatment . . . for some type of skin fungus, no one would pay any attention to it. But because these are such notorious and interesting compounds, they have attracted a lot of peripheral interest to promote and to disseminate; and the risk is that it will be done in the wrong way and there may be consequences,” he said.

Moreover, Lieberman noted that the psychedelic drugs may be used in practice ahead of strong evidence of safety and efficacy. As an example, he pointed to ketamine, a drug that was identified as a treatment for people with depression who had not responded to standard treatments, he noted.

“But before you knew it, there were clinics being opened up all over the place by anesthesiologists or other people that were trying to make a quick buck,” he said.

“That was alarming because they were stretching the criteria for whom the treatment was appropriate; there were no protocols for dosing, for frequency of administration, and there was inadequate psychiatric follow-up,” Lieberman added.
 

Preliminary but promising

He agreed with Kuypers that cases of microdosing with psychedelics are largely anecdotal.

“So in that context, when these investigators tried to put it to a test, which is commendable, the results in no way tell you whether it’s good, bad, or indifferent,” Lieberman said. In fact, the results are “disappointing in terms of suggesting any beneficial effect.”

Lieberman said more and larger studies are needed in order to determine whether LSD microdosing is beneficial. 

In response to Lieberman’s comments, Kuypers told Medscape Medical News that the investigators tried to base their placebo-controlled research on previous anecdotal research.

She emphasized that the “whole field is still in its infancy,” including research on the use of “full” doses of psychedelics.

“I sometimes think that the message is too positive. We should never forget to communicate that not a lot of research has been done.” In addition, she agreed that researchers should “keep a balanced message.”

“All the data to date is preliminary, in my view, but promising,” she stressed, “and the evidence is growing.”

An ADHD brain thrives with daily routines, and requires spontaneity and challenge to remain engaged in work, academics, relationships, and even leisure activities. ADHD is a performance issue and not one of intellectual understanding. It is not a problem of knowing what to do, but rather, difficulty doing it.

The COVID-19 pandemic has led to the loss of structure, with many parents working out of their homes alongside their children engaged in virtual learning. There has been a significant loss of impromptu events, since all activities outside of the house require proper planning and safety precautions.

To help normalize the struggles of the adult patient with ADHD during the pandemic, I have compiled a list of everything I want my adult ADHD patients and their family members to know so they don’t feel shame, guilt, or hopelessness when others’ coping strategies do not work for their ADHD brains.
 

Adult ADHD is a misnomer – and not just a disorder of inattention and hyperactivity

A better name for this often misconstrued disorder is inconsistent attention and motivation disorder with internal or external hyperactivity/impulsivity.

An ADHD brain vacillates between inattention and hyperfocus. It is not uncommon for individuals with ADHD to lose interest in a new television series when they become hyperfocused on finding the best pandemic-friendly toy for their 5-year-olds, which inevitably turns into a 3-hour Google rabbit-hole search.

These same individuals with ADHD may have low motivation for mundane household chores but become highly motivated when their nonessential Amazon purchases arrive. They may even go as far as pulling an all-nighter to have an electric toy jeep built and ready for the youngster by morning.

Adults with ADHD can also exhibit hyperactive symptoms, such as physical restlessness with fidgeting, and an internal restlessness with anxious and repetitive thoughts that affect their ability to unwind, relax, and even sleep. Impulsivity in adults with ADHD can present as rushing through tasks that one finds uninteresting or unimportant, interrupting others on a Zoom work call, or impulse buying an expensive hot tub instead of a more affordable on their spouse agreed to.
 

ADHD is a risk factor for contracting COVID-19

Untreated ADHD can increase one’s risk of contracting COVID-19. Israeli researchers published a study in the Journal of Attention Disorders showing that individuals with ADHD are 52% more likely to test positive for COVID-19, compared with those without ADHD, because of risk-taking behaviors, impulsivity, and carelessness. However, individuals whose ADHD symptoms are treated with stimulant medication do not increase their risk of contracting COVID-19, the researchers wrote.

ADHD might be noticed in family members

ADHD is a neurodevelopmental disorder that affects the development of the brain. We know that structural, functional, and chemical differences affect our patients’ ability to regulate attention, motivation, impulses, and emotions. ADHD tends to run in families and is highly genetic. Since spending more time with family members during the pandemic, patients might even recognize ADHD symptoms in siblings, children, and one or both of parents. A child who has ADHD has a 25% chance of having a parent with ADHD.

Strengths and attributes are related to ADHD

Your ability to thrive in new, stressful, and challenging situations is an ADHD attribute that will be beneficial during the pandemic. Creativity, great problem-solving skills, and ability to be flexible will be admired and helpful to our patients with ADHD and others during these uncertain times.

Those with ADHD might be highly sensitive to their environments

As previously mentioned, ADHD is a misnomer and not just a disorder of inattention but also too much attention. Unfortunately, this hyperfocused attention is usually on the wrong things. Those with ADHD might find it difficult to filter and process sensory information correctly and, therefore, can be easily distracted by auditory, visual, tactile, and olfactory stimuli. The change to working at home during the pandemic might make it hard to ignore children’s voices, the uncomfortable new mask bought after losing yet another mask over the weekend, and the smell of cookies emanating from the kitchen. This increased sensitivity may affect one’s emotions.

Heightened emotions are expected during the pandemic and even more so among adults with ADHD. The inability of adults with ADHD to properly filter information can also affect emotional stimuli. These intense emotions, coupled with impulsive behaviors, can cause disagreements with partners, lack of patience with children, and conflict with colleagues. When individuals with ADHD feel attacked or invalidated, they can become emotionally dysregulated and “vomit” their pent up feelings.
 

ADHD may affect interpersonal relationships

ADHD symptoms of inattention and impulsivity can affect the ability to connect with friends and family. When one is easily distracted by the pandemic’s chaos, it is harder to be mindful and emotionally and physically connected to one’s partner, which also disrupts their sex life and intimacy.

ADHD sensory integration issues can make people sensitive to particular touches, smells, and sensory information. A gentle touch from one’s partner might be annoying during the pandemic, since other senses may already be overstimulated by the loud sounds of children screaming, the visual and auditory distractions of a neighbor mowing the lawn, and the sun beating down because one forgot to get blinds in the home office before the pandemic.

These minor distractions that are usually insignificant to a non-ADHD brain can profoundly affect an ADHD brain since one must use valuable energy to tune out these unwanted disturbances.
 

Your brain uses a different motivational system than a non-ADHD brain

You have a deficiency in the neurotransmitter dopamine, which affects your motivational system. Your motivational system is based on what you find interesting, challenging, new, exciting, and urgent. Your non-ADHD partner, family members, friends, and colleagues motivate and accomplish their daily tasks differently from you and most likely use a system based on rewards and consequences.

Do not be surprised if you notice that your motivation is diminished during the pandemic because of less novelty and excitement in your life. The coronavirus’s chronic importance level may make everything else in your life not as essential and, therefore, less urgent, which indirectly also lowers your motivation.

Your non-ADHD partner may see that you can focus, prioritize, initiate, and complete tasks when you “choose” to, and confuse your inconsistent behaviors as being within your control. However, this lack of motivation for things that do not pique your interest, challenge you, and are not urgent is not voluntary. It is caused by a lack of neural connections in the area of the brain that controls motivation.
 

You can still have ADHD even though you were not diagnosed as a child or adolescent

Your symptoms of ADHD may not affect your level of functioning until you go away to college, obtain your first job, marry your partner, start a family, or even until a global pandemic alters every aspect of your daily life.

It is, therefore, never too late to get assessed and treated for ADHD. Stimulants are the first line of treatment for adult ADHD. Nonstimulants may also be prescribed if you do not tolerate the side effects of stimulants or have a history of certain medical conditions. These options include some antidepressants and high blood pressure medicines. Sometimes, just identifying the deficits of those with ADHD and how they may affect their performance at work, school, and interpersonal relationships can help the person living with ADHD. Many other any nonmedication types of effective treatment are available for adults with ADHD, including therapy, executive skills, and mindfulness training.

• ADHD focused cognitive-behavioral therapy can help one change your distorted, negative, and irrational thoughts about themselves, others, and situations and replace them with more realistic and rational thoughts that allow for helpful and adaptive behaviors.
• Executive skills training is a type of ADHD treatment that focuses on developing effective systems, routines, improving time management, organization, planning, productivity, and emotional self-regulation.
• Mindfulness meditation training is an additional treatment for adult ADHD. Mindfulness training teaches skills to focus on the present moment and become aware of one’s thoughts, emotions, and actions without judgment. The goal is to learn to accept your ADHD deficits and all that is out of your control while remaining mindful of your ADHD strengths and focusing on the daily choices within your control.

Silver linings of the pandemic

Numerous underserved and rural geographic areas lack adequate psychiatric care. Many primary care physicians and even some psychiatrists are uncomfortable diagnosing and treating attentional disorders because of a lack of proper training in medical school and fear related to the fact that the first-line treatment for adult ADHD is a controlled substance.

In response to the pandemic, the expansion of telepsychiatry services, state waivers that allow clinicians to practice across state lines, exemptions that enable the prescribing of controlled substances without an in-person medical evaluation, and the acceptance of employees working from home during the COVID-19 pandemic have increased the accessibility of adult ADHD psychiatric assessments and treatment.

It is hoped that when the COVID-19 pandemic is behind us, many of the benefits that have emerged, such as the growth of telepsychiatry, changes in state licensure and prescriber regulations, and reduced work commutes will continue into our postpandemic lives.

Those with ADHD might find it difficult to filter and process sensory information correctly and, therefore, can be easily distracted by auditory, visual, tactile, and olfactory stimuli. The change to working at home during the pandemic might make it hard to ignore children’s voices, the uncomfortable new mask bought after losing yet another mask over the weekend, and the smell of cookies emanating from the kitchen. This increased sensitivity may affect one’s emotions.

Heightened emotions are expected during the pandemic and even more so among adults with ADHD. The inability of adults with ADHD to properly filter information can also affect emotional stimuli. These intense emotions, coupled with impulsive behaviors, can cause disagreements with partners, lack of patience with children, and conflict with colleagues. When individuals with ADHD feel attacked or invalidated, they can become emotionally dysregulated and “vomit” their pent up feelings.
 

ADHD may affect interpersonal relationships

ADHD symptoms of inattention and impulsivity can affect the ability to connect with friends and family. When one is easily distracted by the pandemic’s chaos, it is harder to be mindful and emotionally and physically connected to one’s partner, which also disrupts their sex life and intimacy.

ADHD sensory integration issues can make people sensitive to particular touches, smells, and sensory information. A gentle touch from one’s partner might be annoying during the pandemic, since other senses may already be overstimulated by the loud sounds of children screaming, the visual and auditory distractions of a neighbor mowing the lawn, and the sun beating down because one forgot to get blinds in the home office before the pandemic.

These minor distractions that are usually insignificant to a non-ADHD brain can profoundly affect an ADHD brain since one must use valuable energy to tune out these unwanted disturbances.
 

Your brain uses a different motivational system than a non-ADHD brain

You have a deficiency in the neurotransmitter dopamine, which affects your motivational system. Your motivational system is based on what you find interesting, challenging, new, exciting, and urgent. Your non-ADHD partner, family members, friends, and colleagues motivate and accomplish their daily tasks differently from you and most likely use a system based on rewards and consequences.

Do not be surprised if you notice that your motivation is diminished during the pandemic because of less novelty and excitement in your life. The coronavirus’s chronic importance level may make everything else in your life not as essential and, therefore, less urgent, which indirectly also lowers your motivation.

Your non-ADHD partner may see that you can focus, prioritize, initiate, and complete tasks when you “choose” to, and confuse your inconsistent behaviors as being within your control. However, this lack of motivation for things that do not pique your interest, challenge you, and are not urgent is not voluntary. It is caused by a lack of neural connections in the area of the brain that controls motivation.
 

You can still have ADHD even though you were not diagnosed as a child or adolescent

Your symptoms of ADHD may not affect your level of functioning until you go away to college, obtain your first job, marry your partner, start a family, or even until a global pandemic alters every aspect of your daily life.

It is, therefore, never too late to get assessed and treated for ADHD. Stimulants are the first line of treatment for adult ADHD. Nonstimulants may also be prescribed if you do not tolerate the side effects of stimulants or have a history of certain medical conditions. These options include some antidepressants and high blood pressure medicines. Sometimes, just identifying the deficits of those with ADHD and how they may affect their performance at work, school, and interpersonal relationships can help the person living with ADHD. Many other any nonmedication types of effective treatment are available for adults with ADHD, including therapy, executive skills, and mindfulness training.

• ADHD focused cognitive-behavioral therapy can help one change your distorted, negative, and irrational thoughts about themselves, others, and situations and replace them with more realistic and rational thoughts that allow for helpful and adaptive behaviors.
• Executive skills training is a type of ADHD treatment that focuses on developing effective systems, routines, improving time management, organization, planning, productivity, and emotional self-regulation.
• Mindfulness meditation training is an additional treatment for adult ADHD. Mindfulness training teaches skills to focus on the present moment and become aware of one’s thoughts, emotions, and actions without judgment. The goal is to learn to accept your ADHD deficits and all that is out of your control while remaining mindful of your ADHD strengths and focusing on the daily choices within your control.

Silver linings of the pandemic

Numerous underserved and rural geographic areas lack adequate psychiatric care. Many primary care physicians and even some psychiatrists are uncomfortable diagnosing and treating attentional disorders because of a lack of proper training in medical school and fear related to the fact that the first-line treatment for adult ADHD is a controlled substance.

In response to the pandemic, the expansion of telepsychiatry services, state waivers that allow clinicians to practice across state lines, exemptions that enable the prescribing of controlled substances without an in-person medical evaluation, and the acceptance of employees working from home during the COVID-19 pandemic have increased the accessibility of adult ADHD psychiatric assessments and treatment.

It is hoped that when the COVID-19 pandemic is behind us, many of the benefits that have emerged, such as the growth of telepsychiatry, changes in state licensure and prescriber regulations, and reduced work commutes will continue into our postpandemic lives.

The disinhibited binge eating style often seen in individuals with high ADHD symptoms is attributable to a heightened neural reward response to food rather than to the impulsivity that’s a core feature of ADHD, Elizabeth Martin, MSc, reported at the virtual congress of the European College of Neuropsychopharmacology.

She presented a functional MRI brain-imaging study designed to help pin down the mechanism involved in the disordered eating patterns that often accompany ADHD.

“Determining the underlying mechanism between binge eating and ADHD may be helpful in developing novel therapies for both ADHD and binge eating disorder. Our research suggests that further investigation of the role of altered reward processing in ADHD may be an avenue for this,” said Ms. Martin, a doctoral researcher in the department of psychology at the University of Birmingham (England).

She and her coinvestigators recruited 31 university student volunteers with high ADHD symptoms as evidenced by their mean score of 29.3 on the 0-54 Conners’ Adult ADHD Rating Scale, and 27 others with low ADHD symptoms and a mean Conners’ score of 6.8. The two groups didn’t differ in age or BMI. However, not surprisingly, the high-ADHD group exhibited greater impulsivity, with a mean score of 72 on the Barratt Impulsiveness Scale, versus 56.5 in the low ADHD group.

A battery of eating disorder scales was applied to assess participants in terms of binge/disinhibited or restrictive eating patterns. The high- and low–ADHD symptom groups didn’t differ in terms of prevalence of a restrictive eating style, which was low, but the high-ADHD participants scored on average roughly 50% higher on the binge/disinhibited eating style measure, compared with the low-ADHD group.

Each study participant underwent a 1-hour BOLD (blood oxygen level dependent) functional MRI scan while performing two sets of tasks. One task entailed quickly looking at 120 photos of food items and an equal number of nonfood items and rating how appealing the pictures were. The other challenge was what psychologists call a go/no-go task, a computerized cognitive test used to assess inhibitory control based upon reaction times and error rates.

On the go/no-go task, there were no between-group differences in rates of errors of omission or commission or reaction time. Moreover, the MRI results indicated there were no between-group differences in neural circuitry activation during this task. The investigators therefore concluded that the tendency toward binge eating in the high–ADHD symptoms group was not tied to greater impulsivity as reflected in less effective inhibitory processes.

The food picture rating task told a different story. The MRIs demonstrated increased responses to food versus nonfood images in the high-ADHD subjects, compared with the low-ADHD subjects in reward-related brain areas, including the ventromedial prefrontal cortex, caudate nucleus, and ventral tegmental area.

“This is the first evidence that ADHD symptoms in young adults are associated with enhanced neural activation in key reward-related brain areas in response to viewing food pictures,” according to Ms. Martin. “This suggests that enhanced responsiveness to food cues may be a mediating mechanism underlying overeating in ADHD.”

Of note, only one drug – lisdexamfetamine dimesylate (Vyvanse) is Food and Drug Administration-approved for the treatment of both ADHD and binge-eating disorder.

“Until now it’s been unclear how lisdexamfetamine dimesylate reduces binge eating, but our results suggest that one mechanism worthy of further investigation is the potential effect of the drug on food reward processes,” Ms. Martin said.

She reported having no financial conflicts regarding the study, which was supported by university funding.

Recent studies constitute a clarion call for clinicians to routinely screen adolescents with ADHD for nonsuicidal self-injury (NSSI) and its risk factors, Judit Balazs, MD, PhD, said at the virtual congress of the European College of Neuropsychopharmacology.

She was lead author of one of these studies, which drew a remarkable and disturbing conclusion: “We found – and it’s a very alarming result – that more than 70% of those people who had ADHD and [nonsuicidal self-injury] were girls. The girls with ADHD seem to be a high-risk population,” observed Dr. Balazs, professor and chair of the department of developmental psychology at Eotvos Lorand University, Budapest.

NSSI first became a specific diagnosis in the DSM-5. It is defined as deliberate, nonculturally sanctioned, nonsuicidal self-injury on at least five occasions within the past year and carried out with the aim of improving one’s emotional state as a result. The prevalence of NSSI among the general population of adolescents is high, with various investigators reporting rates of 15%-45%. Among adolescents with mental disorders, the reported prevalence climbs to 40%-80%. Intriguingly, however, the prevalence of NSSI among adults is just 4%, even though it’s now clear that many cases of pediatric-onset ADHD continue on well into adulthood, albeit often undiagnosed.

Whether NSSI and suicidal behavior are actually the same entity is currently a topic of intense research, according to Dr. Balazs, who is both a child and adolescent psychiatrist, as well as an adult psychiatrist.

She presented highlights of her cross-sectional study of 202 adolescent inpatients, 51% of them female, at the Vadaskert Child and Adolescent Psychiatry Hospital, a tertiary care center in Budapest. Using the structured diagnostic Mini International Neuropsychiatric Interview for Children and Adolescents (MINI Kid) and the self-rated Deliberate Self-Harm Inventory, Dr. Balazs and her coinvestigators determined that 52 of the adolescents, including 23 boys and 29 girls, met full diagnostic criteria for ADHD and another 77 demonstrated more than five subthreshold ADHD symptoms.

Strikingly, 35 of the 52 teens diagnosed with ADHD, or 67%, had current NSSI. Only 10 of these patients were boys. The other 25, or 71% of the total, were girls.

Psychiatric comorbidities proved to be the rule rather than the exception in the adolescent inpatients with ADHD plus NSSI. Among these inpatients, 94% had a history of suicidal behavior. In addition, 66% carried the diagnosis of oppositional defiant disorder, 63% generalized anxiety disorder, 60% had a psychotic disorder, and 51% had experienced a manic episode. Among them, 49% were diagnosed with social anxiety disorder, 46% with obsessive-compulsive disorder, 31% with panic disorder, 23% with conduct disorder, and an equal percentage with agoraphobia. Furthermore, 43% had a major depressive disorder and 34%, dysthymia. Alcohol abuse or dependence was present in 20%, and an equal percentage had psychoactive substance use disorder.

Dr. Balazs said she and her coinvestigators were surprised by the high prevalence of symptoms of comorbid psychotic disorder in conjunction with NSSI and ADHD. One possible explanation, she opined, is that as inpatients the study participants were at the more severe end of the disease spectrum, and some patients may have been admitted not solely because of the severity of their comorbidities. Another possibility is that, in some cases, what was labeled psychotic disorder may actually have been prodromal unipolar depression.

A key finding in Dr. Balazs’s study was that, according to a regression analysis, the relationship between ADHD and NSSI was mediated entirely by the symptoms of the ADHD comorbidities. Specifically, the significant risk factors for NSSI in patients with ADHD were affective disorders, suicidality, and psychotic disorders in both sexes, with the addition of comorbid alcohol abuse or dependence in girls only. There was no evidence of a direct causal relationship between ADHD, per se, and NSSI.
 

‘Findings warrant further investigation’

The study, which looks at the association between NSSI and adolescents is interesting, yet preliminary, said David Fassler, MD, in an interview.

“The authors conclude that girls with ADHD are at particularly high risk of NSSI,” said Dr. Fassler, clinical professor of psychiatry at the University of Vermont, Burlington. Dr. Fassler was not involved with the study.

“It is limited by sample size, acuity, and the incidence of comorbidities,” said Dr. Fassler, who had no conflicts of interest. “Nonetheless, the findings are intriguing and warrant further investigation with larger samples in diverse clinical settings.”

The study was supported by the Hungarian Scientific Research Fund. In addition, Dr. Balazs received funding from the Hungarian Academy of Sciences. The full details of the study have been published (BMC Psychiatry. 2018 Feb 6;18[1]:34).

Young people with certain learning disorders, such as attention-deficit disorder/attention-deficit/hyperactivity disorder (ADD/ADHD) and dyslexia, can perform worse on commonly used concussion tests, a new study shows.

“Our results suggest kids with certain learning disorders may respond differently to concussion tests, and this needs to be taken into account when advising on recovery times and when they can return to sport,” said lead author Mathew Stokes, MD. Dr. Stokes is assistant professor of pediatrics and neurology/neurotherapeutics at the University of Texas–Southwestern Medical Center, Dallas.

The study was presented at the American Academy of Neurology Sports Concussion Virtual Conference, held online July 31 to Aug. 1.
 

Learning disorders affected scores

The researchers analyzed data from participants aged 10-18 years who were enrolled in the North Texas Concussion Registry (ConTex). Participants had been diagnosed with a concussion that was sustained within 30 days of enrollment. The researchers investigated whether there were differences between patients who had no history of learning disorders and those with a history of dyslexia and/or ADD/ADHD with regard to results of clinical testing following concussion.

Of the 1,298 individuals in the study, 58 had been diagnosed with dyslexia, 158 had been diagnosed with ADD/ADHD, and 35 had been diagnosed with both conditions. There was no difference in age, time since injury, or history of concussion between those with learning disorders and those without, but there were more male patients in the ADD/ADHD group.

Results showed that in the dyslexia group, mean time was slower (P = .011), and there was an increase in error scores on the King-Devick (KD) test (P = .028). That test assesses eye movements and involves the rapid naming of numbers that are spaced differently. In addition, those with ADD/ADHD had significantly higher impulse control scores (P = .007) on the ImPACT series of tests, which are commonly used in the evaluation of concussion. Participants with both dyslexia and ADHD demonstrated slower KD times (P = .009) and had higher depression scores and anxiety scores.

Dr. Stokes noted that a limiting factor of the study was that baseline scores were not available. “It is possible that kids with ADD have less impulse control even at baseline, and this would need to be taken into account,” he said. “You may perhaps also expect someone with dyslexia to have a worse score on the KD tests, so we need more data on how these scores are affected from baseline in these individuals. But our results show that when evaluating kids pre- or post concussion, it is important to know about learning disorders, as this will affect how we interpret the data.”

At 3-month follow-up, there were no longer significant differences in anxiety and depression scores for those with and those without learning disorders. “This suggests anxiety and depression may well be worse temporarily after concussion for those with ADD/ADHD but gets better with time,” Dr. Stokes said.

Follow-up data were not available for the other cognitive tests.
 

Are recovery times longer?

Asked whether young people with these learning disorders needed a longer time to recover after concussion, Dr. Stokes said: “That is a million-dollar question. Studies so far on this have shown conflicting results. Our results add to a growing body of literature on this.” He stressed that it is important to include anxiety and depression scores on both baseline and postconcussion tests. “People don’t tend to think of these symptoms as being associated with concussion, but they are actually very prominent in this situation,” he noted. “Our results suggest that individuals with ADHD may be more prone to anxiety and depression, and a blow to the head may tip them more into these symptoms.”

Discussing the study at a virtual press conference as part of the AAN Sports Concussion meeting, the codirector of the meeting, David Dodick, MD, Mayo Clinic, Scottsdale, Ariz., said: “This is a very interesting and important study which suggests there are differences between adolescents with a history of dyslexia/ADHD and those without these conditions in performance in concussion tests. Understanding the differences in these groups will help health care providers in evaluating these athletes and assisting in counseling them and their families with regard to their risk of injury.

“It is important to recognize that athletes with ADHD, whether or not they are on medication, may take longer to recover from a concussion,” Dr. Dodick added. They also exhibit greater reductions in cognitive skills and visual motor speed regarding hand-eye coordination, he said. There is an increase in the severity of symptoms. “Symptoms that exist in both groups tend to more severe in those individuals with ADHD,” he noted.

“Ascertaining the presence or absence of ADHD or dyslexia in those who are participating in sport is important, especially when trying to interpret the results of baseline testing, the results of postinjury testing, decisions on when to return to play, and assessing for individuals and their families the risk of long-term repeat concussions and adverse outcomes,” he concluded.

The other codirector of the AAN meeting, Brian Hainline, MD, chief medical officer of the National Collegiate Athletic Association, added: “It appears that athletes with ADHD may suffer more with concussion and have a longer recovery time. This can inform our decision making and help these individuals to understand that they are at higher risk.”

Dr. Hainline said this raises another important point: “Concussion is not a homogeneous entity. It is a brain injury that can manifest in multiple parts of the brain, and the way the brain is from a premorbid or comorbid point of view can influence the manifestation of concussion as well,” he said. “All these things need to be taken into account.”

Attentional deficit may itself make an individual more susceptible to sustaining an injury in the first place, he said. “All of this is an evolving body of research which is helping clinicians to make better-informed decisions for athletes who may manifest differently.”

Young people with certain learning disorders, such as attention-deficit disorder/attention-deficit/hyperactivity disorder (ADD/ADHD) and dyslexia, can perform worse on commonly used concussion tests, a new study shows.

“Our results suggest kids with certain learning disorders may respond differently to concussion tests, and this needs to be taken into account when advising on recovery times and when they can return to sport,” said lead author Mathew Stokes, MD. Dr. Stokes is assistant professor of pediatrics and neurology/neurotherapeutics at the University of Texas–Southwestern Medical Center, Dallas.

The study was presented at the American Academy of Neurology Sports Concussion Virtual Conference, held online July 31 to Aug. 1.
 

Learning disorders affected scores

The researchers analyzed data from participants aged 10-18 years who were enrolled in the North Texas Concussion Registry (ConTex). Participants had been diagnosed with a concussion that was sustained within 30 days of enrollment. The researchers investigated whether there were differences between patients who had no history of learning disorders and those with a history of dyslexia and/or ADD/ADHD with regard to results of clinical testing following concussion.

Of the 1,298 individuals in the study, 58 had been diagnosed with dyslexia, 158 had been diagnosed with ADD/ADHD, and 35 had been diagnosed with both conditions. There was no difference in age, time since injury, or history of concussion between those with learning disorders and those without, but there were more male patients in the ADD/ADHD group.

Results showed that in the dyslexia group, mean time was slower (P = .011), and there was an increase in error scores on the King-Devick (KD) test (P = .028). That test assesses eye movements and involves the rapid naming of numbers that are spaced differently. In addition, those with ADD/ADHD had significantly higher impulse control scores (P = .007) on the ImPACT series of tests, which are commonly used in the evaluation of concussion. Participants with both dyslexia and ADHD demonstrated slower KD times (P = .009) and had higher depression scores and anxiety scores.

Dr. Stokes noted that a limiting factor of the study was that baseline scores were not available. “It is possible that kids with ADD have less impulse control even at baseline, and this would need to be taken into account,” he said. “You may perhaps also expect someone with dyslexia to have a worse score on the KD tests, so we need more data on how these scores are affected from baseline in these individuals. But our results show that when evaluating kids pre- or post concussion, it is important to know about learning disorders, as this will affect how we interpret the data.”

At 3-month follow-up, there were no longer significant differences in anxiety and depression scores for those with and those without learning disorders. “This suggests anxiety and depression may well be worse temporarily after concussion for those with ADD/ADHD but gets better with time,” Dr. Stokes said.

Follow-up data were not available for the other cognitive tests.
 

Are recovery times longer?

Asked whether young people with these learning disorders needed a longer time to recover after concussion, Dr. Stokes said: “That is a million-dollar question. Studies so far on this have shown conflicting results. Our results add to a growing body of literature on this.” He stressed that it is important to include anxiety and depression scores on both baseline and postconcussion tests. “People don’t tend to think of these symptoms as being associated with concussion, but they are actually very prominent in this situation,” he noted. “Our results suggest that individuals with ADHD may be more prone to anxiety and depression, and a blow to the head may tip them more into these symptoms.”

Recently, the Yakima Health District (YHD), in collaboration with the Washington State Department of Health, issued dramatic revisions to its educational curriculum, opting for exclusively remote learning as an important next step in COVID-19 containment measures.

The newly implemented “enhanced” distance-learning paradigm has garnered considerable national attention. Even more noteworthy is how YHD addressed those with language barriers and learning differences such as ADHD as a “priority group”; these individuals are exempt from the newly implemented measures, and small instructional groups of no more than five “at-risk” students will be directly supervised by specialized educators.^1,2 To overcome these new unprecedented challenges from the coronavirus pandemic, especially from the perspective of distance education and mental health for susceptible groups such as those with ADHD, it is of utmost importance to explore various programs of interest, as well as the targeted therapies being considered during this crisis.

From a therapeutic standpoint, individuals with learning differences are more likely to play catch-up with their age-matched peers. This puts them at significant risk for developmental delays with symptoms manifesting as disruptive behavioral issues. This is why ongoing parental guidance, coupled with a paradoxically stimulating environment, is critical for children and adolescents with ADHD.³ Accumulating evidence, based on a myriad of studies, demonstrates that childhood treatment with ADHD stimulants reduces the incidence of future substance use, as well as that of other negative outcomes.^4,5

Therapeutic strategies that work

“The new normal” has forced unique challenges on clinicians for mitigating distress by novel means of health care delivery. Given the paucity of research exploring the interactions of individuals with ADHD within the context of COVID-19, American clinicians may need to draw inspiration from international pandemic studies in accordance with evidence-based medicine. Take for example, the suggested guidelines from the European ADHD Guidelines Group (EAGG) – such as the following:

• Telecommunications in general, and telepsychiatry in particular, should function as the primary mode of health care delivery to fulfill societal standards of physical distancing.
• Children and adolescents with ADHD should be designated as a “priority group” with respect to monitoring initiatives by educators in a school setting, be it virtual or otherwise.
• Implementation of behavioral strategies by parent or guardian to address psychological well-being and reduce the presence of comorbid behavioral conditions (such as oppositional defiant disorder).

In addition to the aforementioned guidance, EAGG maintains that individuals with ADHD may be initiated on medications after the completion of a baseline examination; if the patients in question are already on a treatment regimen, they should proceed with it as indicated. Interruptions to therapy are not ideal because patients are then subjected to health-related stressors of COVID-19. Reasonable regulations concerning access to medications, without unnecessary delays, undoubtedly will facilitate patient needs, allowing for a smooth transition in day-to-day activities. The family, as a cohesive unit, may benefit from reeducation because it contributes toward the therapeutic process. Neurofeedback, coping skills, and cognitive restructuring training are potential modalities that can augment medications.

Although it may seem counterintuitive, parents or caregivers should resist the urge to increase the medication dose during an outbreak with the intended goal of diminishing the psychosocial burden of ADHD symptomatology. Likewise, unless indicated by a specialist, antipsychotics and/or hypnotics should not be introduced for addressing behavioral dysregulation (such as agitation) during the confinement period.

Historically, numerous clinicians have suggested that patients undergo a routine cardiovascular examination and EKG before being prescribed psychostimulants (the rationale for this recommendation is that sympathomimetics unduly affect blood pressure and heart rate).^6,7 However, the American Academy of Pediatrics (AAP) and the American Heart Association (AHA) eventually amended their previous stance by releasing a joint statement in which they deemed a baseline EKG necessary only in ADHD patients with preexisting cardiac risk. For all other patients, the use of EKGs was entirely contingent on physician discretion. However, given the nature of safety precautions for COVID-19, it is prudent to discourage or delay in-person cardiovascular examination/monitoring protocols altogether, especially in those patients without known heart conditions.

Another area of concern is sleep dysfunction, which might exist as an untoward effect of ADHD medication intake or because of the presence of COVID-19 psychosocial stressors. However, clinicians advise that unnecessary psychopharmacology (such as hypnotics or melatonin) be avoided. Instead, conservative lifestyle measures should be enacted, emphasizing the role of proper sleep hygiene in maintaining optimal behavioral health. Despite setbacks to in-person appointments, patients are expected to continue their pharmacotherapy with “parent-focused” ADHD interventions taking a primary role in facilitating compliance through remote monitoring.

ADMiRE, a tertiary-level, dedicated ADHD intervention program from South Dublin, Ireland, has identified several roadblocks with respect to streamlining health care for individuals with ADHD during the confinement period. The proposed resolution to these issues, some of which are derived from EAGG guidelines, might have universal applications elsewhere, thereby facilitating the development of therapeutic services of interest. ADMiRE has noted a correspondence between the guidelines established by EAGG and that of the Canadian ADHD Resource Alliance (CADDRA), including minimal in-person interactions (in favor of virtual teleconferencing) and a cardiovascular screen can be performed in lieu of baseline cardiac auscultation. Moreover, in the event that the patient is a low cardiac risk candidate for ADHD treatment, monitoring protocols may be continued from a home setting. However, if a physical examination is indicated, CADDRA recommends the use of precautionary PPE before commencing ADHD pharmacotherapy.

One of the most significant hurdles is that of school closures because teacher feedback for baseline behavior was traditionally instrumental in dictating patient medical management (for example, for titration schedule). It is expected that, for the time being, this role will be supplanted by parental reports. As well as disclosing information on behavioral dysregulation, family members should be trained to relay critical information about the development of stimulant-induced cardiovascular symptoms – namely, dyspnea, chest pain, and/or palpitations. Furthermore, as primary caregivers, parents should harbor a certain degree of emotional sensitivity because their mood state may influence the child’s overall behavioral course in terms of symptom exacerbation.⁸

 

Toward adopting an integrated model for care

Developing an effective assessment plan for patients with ADHD often proves to be a challenging task for clinicians, perhaps even more so in environments that enforce social distancing and limited physical contact by default. As a neurodevelopmental disorder from childhood, the symptoms (including inattention, hyperactivity, and/or impulsivity) of ADHD do not arise in a vacuum – comorbid conditions include mood and anxiety disorders, which are complicated further by a background risk for substance use and self-medicating tendencies.⁹ Unfortunately, the pandemic has limited the breadth of non-COVID doctors visits, which hinders the overall diagnostic and monitoring process for identifiable comorbid conditions, such as autism spectrum disorder, intellectual disability, oppositional defiant and conduct disorders, and so on.¹⁰ Since ADHD symptoms cannot be treated by pharmacotherapy or behavioral interventions alone, our team advocates that families provide additional emotional support and continuous encouragement during these uncertain times.

ADHD and the self-medication hypothesis

The Khantzian self-medication hypothesis posits that a drug seeker may subconsciously gravitate toward a particular agent only to discover a sense of relief concerning inner turmoil or restlessness after use. Observations support the notion that individuals with undiagnosed ADHD have sought cocaine or even recreational designer drugs (such as methylenedioxypyrovalerone, or “bath salts”).¹¹ Given the similar mechanism of action between cocaine, methylenedioxypyrovalerone, and prescribed psychostimulants such as methylphenidate, the results are hardly surprising because these agents all work on the brain’s “reward center” (for example, the nucleus accumbens) by invoking dopamine release. Aside from the aforementioned self-medication hypothesis, “downers” such as Xanax recently have experienced a prescription spike during the outbreak. While there isn’t an immediate cause for concern of Xanax abuse in ADHD individuals, the potential for addiction is certainly real, especially when taking into account comorbid anxiety disorder or sleep dysfunction.

Because of limited resources and precautionary guidelines, clinicians are at a considerable disadvantage in terms of formulating a comprehensive diagnostic and treatment plan for children and adolescents with ADHD. This situation is further compounded by the recent closure of schools and the lack of feedback with respect to baseline behavior from teachers and specialized educators. This is why it is imperative for primary caregivers to closely monitor children with ADHD for developing changes in behavioral patterns (for example, mood or anxiety issues and drug-seeking or disruptive behavior) and work with health care professionals.

“The new normal” has forced unique challenges on clinicians for mitigating distress by novel means of health care delivery. Given the paucity of research exploring the interactions of individuals with ADHD within the context of COVID-19, American clinicians may need to draw inspiration from international pandemic studies in accordance with evidence-based medicine. Take for example, the suggested guidelines from the European ADHD Guidelines Group (EAGG) – such as the following:

• Telecommunications in general, and telepsychiatry in particular, should function as the primary mode of health care delivery to fulfill societal standards of physical distancing.
• Children and adolescents with ADHD should be designated as a “priority group” with respect to monitoring initiatives by educators in a school setting, be it virtual or otherwise.
• Implementation of behavioral strategies by parent or guardian to address psychological well-being and reduce the presence of comorbid behavioral conditions (such as oppositional defiant disorder).

In addition to the aforementioned guidance, EAGG maintains that individuals with ADHD may be initiated on medications after the completion of a baseline examination; if the patients in question are already on a treatment regimen, they should proceed with it as indicated. Interruptions to therapy are not ideal because patients are then subjected to health-related stressors of COVID-19. Reasonable regulations concerning access to medications, without unnecessary delays, undoubtedly will facilitate patient needs, allowing for a smooth transition in day-to-day activities. The family, as a cohesive unit, may benefit from reeducation because it contributes toward the therapeutic process. Neurofeedback, coping skills, and cognitive restructuring training are potential modalities that can augment medications.

Although it may seem counterintuitive, parents or caregivers should resist the urge to increase the medication dose during an outbreak with the intended goal of diminishing the psychosocial burden of ADHD symptomatology. Likewise, unless indicated by a specialist, antipsychotics and/or hypnotics should not be introduced for addressing behavioral dysregulation (such as agitation) during the confinement period.

Historically, numerous clinicians have suggested that patients undergo a routine cardiovascular examination and EKG before being prescribed psychostimulants (the rationale for this recommendation is that sympathomimetics unduly affect blood pressure and heart rate).^6,7 However, the American Academy of Pediatrics (AAP) and the American Heart Association (AHA) eventually amended their previous stance by releasing a joint statement in which they deemed a baseline EKG necessary only in ADHD patients with preexisting cardiac risk. For all other patients, the use of EKGs was entirely contingent on physician discretion. However, given the nature of safety precautions for COVID-19, it is prudent to discourage or delay in-person cardiovascular examination/monitoring protocols altogether, especially in those patients without known heart conditions.

Another area of concern is sleep dysfunction, which might exist as an untoward effect of ADHD medication intake or because of the presence of COVID-19 psychosocial stressors. However, clinicians advise that unnecessary psychopharmacology (such as hypnotics or melatonin) be avoided. Instead, conservative lifestyle measures should be enacted, emphasizing the role of proper sleep hygiene in maintaining optimal behavioral health. Despite setbacks to in-person appointments, patients are expected to continue their pharmacotherapy with “parent-focused” ADHD interventions taking a primary role in facilitating compliance through remote monitoring.

ADMiRE, a tertiary-level, dedicated ADHD intervention program from South Dublin, Ireland, has identified several roadblocks with respect to streamlining health care for individuals with ADHD during the confinement period. The proposed resolution to these issues, some of which are derived from EAGG guidelines, might have universal applications elsewhere, thereby facilitating the development of therapeutic services of interest. ADMiRE has noted a correspondence between the guidelines established by EAGG and that of the Canadian ADHD Resource Alliance (CADDRA), including minimal in-person interactions (in favor of virtual teleconferencing) and a cardiovascular screen can be performed in lieu of baseline cardiac auscultation. Moreover, in the event that the patient is a low cardiac risk candidate for ADHD treatment, monitoring protocols may be continued from a home setting. However, if a physical examination is indicated, CADDRA recommends the use of precautionary PPE before commencing ADHD pharmacotherapy.

One of the most significant hurdles is that of school closures because teacher feedback for baseline behavior was traditionally instrumental in dictating patient medical management (for example, for titration schedule). It is expected that, for the time being, this role will be supplanted by parental reports. As well as disclosing information on behavioral dysregulation, family members should be trained to relay critical information about the development of stimulant-induced cardiovascular symptoms – namely, dyspnea, chest pain, and/or palpitations. Furthermore, as primary caregivers, parents should harbor a certain degree of emotional sensitivity because their mood state may influence the child’s overall behavioral course in terms of symptom exacerbation.⁸

 

Toward adopting an integrated model for care

Developing an effective assessment plan for patients with ADHD often proves to be a challenging task for clinicians, perhaps even more so in environments that enforce social distancing and limited physical contact by default. As a neurodevelopmental disorder from childhood, the symptoms (including inattention, hyperactivity, and/or impulsivity) of ADHD do not arise in a vacuum – comorbid conditions include mood and anxiety disorders, which are complicated further by a background risk for substance use and self-medicating tendencies.⁹ Unfortunately, the pandemic has limited the breadth of non-COVID doctors visits, which hinders the overall diagnostic and monitoring process for identifiable comorbid conditions, such as autism spectrum disorder, intellectual disability, oppositional defiant and conduct disorders, and so on.¹⁰ Since ADHD symptoms cannot be treated by pharmacotherapy or behavioral interventions alone, our team advocates that families provide additional emotional support and continuous encouragement during these uncertain times.

ADHD and the self-medication hypothesis

The Khantzian self-medication hypothesis posits that a drug seeker may subconsciously gravitate toward a particular agent only to discover a sense of relief concerning inner turmoil or restlessness after use. Observations support the notion that individuals with undiagnosed ADHD have sought cocaine or even recreational designer drugs (such as methylenedioxypyrovalerone, or “bath salts”).¹¹ Given the similar mechanism of action between cocaine, methylenedioxypyrovalerone, and prescribed psychostimulants such as methylphenidate, the results are hardly surprising because these agents all work on the brain’s “reward center” (for example, the nucleus accumbens) by invoking dopamine release. Aside from the aforementioned self-medication hypothesis, “downers” such as Xanax recently have experienced a prescription spike during the outbreak. While there isn’t an immediate cause for concern of Xanax abuse in ADHD individuals, the potential for addiction is certainly real, especially when taking into account comorbid anxiety disorder or sleep dysfunction.

Because of limited resources and precautionary guidelines, clinicians are at a considerable disadvantage in terms of formulating a comprehensive diagnostic and treatment plan for children and adolescents with ADHD. This situation is further compounded by the recent closure of schools and the lack of feedback with respect to baseline behavior from teachers and specialized educators. This is why it is imperative for primary caregivers to closely monitor children with ADHD for developing changes in behavioral patterns (for example, mood or anxiety issues and drug-seeking or disruptive behavior) and work with health care professionals.

Concussion is associated with increased risk for subsequent development of attention-deficit/hyperactivity disorder (ADHD), as well as dementia and Parkinson’s disease, new research suggests. Results from a retrospective, population-based cohort study showed that controlling for socioeconomic status and overall health did not significantly affect this association.

The link between concussion and risk for ADHD and for mood and anxiety disorder was stronger in the women than in the men. In addition, having a history of multiple concussions strengthened the association between concussion and subsequent mood and anxiety disorder, dementia, and Parkinson’s disease compared with experiencing just one concussion.

The findings are similar to those of previous studies, noted lead author Marc P. Morissette, PhD, research assistant at the Pan Am Clinic Foundation in Winnipeg, Manitoba, Canada. “The main methodological differences separating our study from previous studies in this area is a focus on concussion-specific injuries identified from medical records and the potential for study participants to have up to 25 years of follow-up data,” said Dr. Morissette.

The findings were published online July 27 in Family Medicine and Community Health, a BMJ journal.
 

Almost 190,000 participants

Several studies have shown associations between head injury and increased risk for ADHD, depression, anxiety, Alzheimer’s disease, and Parkinson’s disease. However, many of these studies relied on self-reported medical history, included all forms of traumatic brain injury, and failed to adjust for preexisting health conditions.

An improved understanding of concussion and the risks associated with it could help physicians manage their patients’ long-term needs, the investigators noted.

In the current study, the researchers examined anonymized administrative health data collected between the periods of 1990–1991 and 2014–2015 in the Manitoba Population Research Data Repository at the Manitoba Center for Health Policy.

Eligible patients had been diagnosed with concussion in accordance with standard criteria. Participants were excluded if they had been diagnosed with dementia or Parkinson’s disease before the incident concussion during the study period. The investigators matched three control participants to each included patient on the basis of age, sex, and location.

Study outcome was time from index date (date of first concussion) to diagnosis of ADHD, mood and anxiety disorder, dementia, or Parkinson’s disease. The researchers controlled for socioeconomic status using the Socioeconomic Factor Index, version 2 (SEFI2), and for preexisting medical conditions using the Charlson Comorbidity Index (CCI).

The study included 28,021 men (mean age, 25 years) and 19,462 women (mean age, 30 years) in the concussion group and 81,871 men (mean age, 25 years) and 57,159 women (mean age, 30 years) in the control group. Mean SEFI2 score was approximately −0.05, and mean CCI score was approximately 0.2.
 

Dose effect?

Results showed that concussion was associated with an increased risk for ADHD (hazard ratio [HR], 1.39), mood and anxiety disorder (HR, 1.72), dementia (HR, 1.72), and Parkinson’s disease (HR, 1.57).

After a concussion, the risk of developing ADHD was 28% higher and the risk of developing mood and anxiety disorder was 7% higher among women than among men. Gender was not associated with risk for dementia or Parkinson’s disease after concussion.

Sustaining a second concussion increased the strength of the association with risk for dementia compared with sustaining a single concussion (HR, 1.62). Similarly, sustaining more than three concussions increased the strength of the association with the risk for mood and anxiety disorders (HR for more than three vs one concussion, 1.22) and Parkinson›s disease (HR, 3.27).

A sensitivity analysis found similar associations between concussion and risk for mood and anxiety disorder among all age groups. Younger participants were at greater risk for ADHD, however, and older participants were at greater risk for dementia and Parkinson’s disease.

Increased awareness of concussion and the outcomes of interest, along with improved diagnostic tools, may have influenced the study’s findings, Dr. Morissette noted. “The sex-based differences may be due to either pathophysiological differences in response to concussive injuries or potentially a difference in willingness to seek medical care or share symptoms, concussion-related or otherwise, with a medical professional,” he said.

“We are hopeful that our findings will encourage practitioners to be cognizant of various conditions that may present in individuals who have previously experienced a concussion,” Dr. Morissette added. “If physicians are aware of the various associations identified following a concussion, it may lead to more thorough clinical examination at initial presentation, along with more dedicated care throughout the patient’s life.”
 

Association versus causation

Commenting on the research, Steven Erickson, MD, sports medicine specialist at Banner–University Medicine Neuroscience Institute, Phoenix, Ariz., noted that although the study showed an association between concussion and subsequent diagnosis of ADHD, anxiety, and Parkinson’s disease, “this association should not be misconstrued as causation.” He added that the study’s conclusions “are just as likely to be due to labeling theory” or a self-fulfilling prophecy.

“Patients diagnosed with ADHD, anxiety, or Parkinson’s disease may recall concussion and associate the two diagnoses; but patients who have not previously been diagnosed with a concussion cannot draw that conclusion,” said Dr. Erickson, who was not involved with the research.

Citing the apparent gender difference in the strength of the association between concussion and the outcomes of interest, Dr. Erickson noted that women are more likely to report symptoms in general “and therefore are more likely to be diagnosed with ADHD and anxiety disorders” because of differences in reporting rather than incidence of disease.

“Further research needs to be done to definitively determine a causal relationship between concussion and any psychiatric or neurologic diagnosis,” Dr. Erickson concluded.

The study was funded by the Pan Am Clinic Foundation. Dr. Morissette and Dr. Erickson have disclosed no relevant financial relationships.
