Patterns of Child and Adolescent Psychiatric Admissions During COVID-19: Key Insights from Clinical Data

A recent study from Istanbul sheds light on how psychiatric admissions and diagnoses changed during the first few months of the pandemic compared to previous periods, offering critical insights for parents, clinicians, and policymakers. 

This study, conducted by a team of researchers led by Ozalp Ekinci, examined psychiatric admissions among children and adolescents during 2019 and 2020. 

By looking at diagnosis rates for various psychiatric conditions, the researchers aimed to pinpoint shifts in the mental health landscape as a direct response to the pandemic.

Findings: A Closer Look at Diagnosis Patterns

The analysis revealed several notable trends in psychiatric diagnoses among children and adolescents:

  1. Autism Spectrum Disorder (ASD): ASD diagnoses were notably higher in the early pandemic phase (6.4% in Group A) compared to the same period in the previous year (3.6%). This increase could reflect heightened stress or changes in routines that may have exacerbated underlying symptoms, leading to more frequent clinical presentations.
  2. Obsessive-Compulsive Disorder (OCD) and Tic Disorders: OCD and tic disorder diagnoses also saw a rise, increasing from 1.7% in 2019 to 2.9% during the pandemic’s onset. It’s possible that pandemic-driven anxieties and hygiene concerns, as well as disruptions to typical routines, may have worsened symptoms in those predisposed to OCD and similar disorders.
  3. Intellectual Disability (ID): Diagnoses for ID rose from 2.1% (Group C) to 3.7% (Group A). This increase highlights the challenges faced by children with developmental and intellectual disabilities, who may have experienced heightened difficulty adapting to the many changes imposed by the pandemic.
  4. Attention-Deficit Hyperactivity Disorder (ADHD): ADHD diagnoses were significantly higher in the pandemic phase (59.8% for Group A vs. 49.7% for Group B). With altered school structures, remote learning, and restricted socialization, ADHD symptoms could have been amplified, making it harder for children to concentrate and adhere to routines.
  5. Depression: Depression diagnoses also saw a rise (4.1% in Group A vs. 2.2% in Group C). Isolation, disruption of daily activities, and reduced social interactions likely contributed to increased depressive symptoms, particularly in adolescents who rely heavily on peer support.
  6. Conduct Disorder (CD): Interestingly, CD diagnoses were lower during the pandemic phase compared to pre-pandemic levels (3.6% in Group A vs. 6.4% in Group B). The reduction in face-to-face interactions and less exposure to traditional school settings may have lessened some of the typical triggers associated with conduct-related issues.
Implications

This study’s findings highlight some key takeaways that can guide mental health support efforts for children and adolescents:

  1. Increased Need for Early Support in Neurodevelopmental Disorders: The rise in ASD and ADHD diagnoses points to the need for specialized support in times of crisis, particularly for children who depend on routine and structure. Families and educators should work to create consistent environments that help manage symptoms.
  2. Addressing Pandemic-Induced Anxiety: With heightened cases of OCD and tic disorders, it’s clear that the pandemic’s emphasis on cleanliness and health may have intensified anxiety-driven behaviors. Future mental health responses should include strategies to manage health-related fears and equip children with coping skills.
  3. Supporting Emotional Resilience in Adolescents: Depression was notably higher among young people during the pandemic onset, suggesting a critical need for access to counseling and peer support, especially in times of isolation. Developing robust virtual mental health resources and promoting mental well-being in schools can help support children and adolescents both in and out of school.
  4. Recognizing the Complexity of Behavioral Changes: The drop in conduct disorder diagnoses during the pandemic suggests a link between behavioral disorders and social settings. Understanding these dynamics could lead to more tailored interventions that account for environmental factors impacting behavior.
Conclusion: 

As we continue to see the effects of the COVID-19 pandemic on mental health, studies like this one serve as important reminders of the unique mental health needs of young people. Supporting children and adolescents through proactive and targeted mental health services—especially during times of crisis—will be crucial to fostering resilience and well-being in future generations.

For Adults with ADHD: What Should you Doctor be Doing for your ADHD?

For Adults with ADHD: What Should Your Doctor be Doing for your ADHD?

Recognizing whether your ADHD is being managed appropriately requires an understanding of what constitutes effective treatment. Here are some indicators of proper ADHD treatment:

Recognizing whether your ADHD is being managed appropriately requires an understanding of what constitutes effective treatment. Here are some indicators of proper ADHD treatment:

Comprehensive Evaluation: An appropriate diagnosis of ADHD involves a comprehensive evaluation, including medical history, clinical interviews, and assessment tools. It should also exclude other conditions that may mimic ADHD.

Clear Communication: Your doctor should provide a clear explanation of ADHD, its symptoms, treatment options, potential side effects, and expected outcomes. They should answer your questions patiently and help dispel any misconceptions.

Individualized Treatment Plan: ADHD treatment often involves a combination of medication, psychotherapy, and lifestyle changes. Your doctor should tailor the treatment plan to your specific needs, symptoms, and life circumstances.

Medication Management: If medication is part of your treatment plan, your doctor should monitor its effects and side effects closely, adjusting the dosage as necessary. Remember, the aim is to maximize benefits and minimize side effects.  Much research shows that it is usually best to start treatment with an FDA approved medication.  If your doctor decides otherwise, you should ask why.

Psychotherapy and Coaching: Pills don’t provide skills.  Many adults with ADHD never acquired life skills due to untreated ADHD. Cognitive-behavioral therapy (CBT) is beneficial for managing ADHD. Your doctor might recommend this and refer you to a psychologist, or they might provide some elements of these services themselves.  

Regular Follow-Ups: Regular follow-ups are critical to assess the effectiveness of the treatment plan and to make necessary adjustments. Your doctor should be tracking your progress and adapting your treatment as needed.

Empowering You: A good doctor will support you in managing your ADHD, providing education, resources, and tools that empower you to lead a healthy, fulfilling life.

Focus on Strengths: ADHD can come with strengths, such as creativity, dynamism, and the ability to think outside the box. An effective healthcare provider will help you leverage these strengths.

Involvement of Loved Ones: Depending on your circumstances, involving your loved ones in your treatment process can be beneficial. They can provide additional support and understanding.

Co-ordinating with Other Healthcare Providers: If you have other healthcare providers involved in your care, your doctor should communicate and coordinate with them to ensure consistent and comprehensive care.

Remember, you have the right to seek a second opinion if you feel your ADHD is not being appropriately managed. Trust your instincts and advocate for your health. It may also be helpful to join ADHD support groups (online or offline) to connect with others who share similar experiences. Their insights and recommendations could be beneficial.  Also keep in mind that achieving an optimal outcome for one’s ADHD often requires the doctor to try a few different medications as it is not currently possible to predict which patients do best on which medications.

Hong Kong population study finds methylphenidate use is associated with reduced risk of fractures among persons with ADHD

Hong Kong Population Study Finds Methylphenidate Use is Associated With Reduced Risk of Fractures Among Persons with ADHD

Some animal studies and laboratory experiments have suggested that methylphenidate, the most widely prescribed pharmaceutical to treat ADHD, may weaken bones. On the other hand, other studies have indicated that methylphenidate is associated with lower risk of injury.

Some animal studies and laboratory experiments have suggested that methylphenidate, the most widely prescribed pharmaceutical to treat ADHD, may weaken bones. On the other hand, other studies have indicated that methylphenidate is associated with lower risk of injury.

What, then, is the overall effect? 

The Hong Kong Hospital Authority is the sole public health provider for the city’s 7.3 million residents. Using the Clinical Data Analysis and Reporting System, the Authority’s electronic database, an international study team set out to explore this question.

Among 43,841 individuals with ADHD medication, the team identified 2,023 children and youths 5 through 24 years old with both methylphenidate prescription and a fracture between January 2001 and December 2020. 

In the six months following prescription, individuals were found to be roughly 40% less likely to be treated for a fracture than in the six months prior to prescription. The same held true when comparing the period 7 to 12 months after prescription with the six months prior to prescription. 

As a control, the team also looked at the effect of methylphenidate prescription on a completely unrelated condition – diseases of the esophagus, stomach, and duodenum. 

In this case, there was absolutely no difference in disease incidence for equal periods of time before and after initiation of methylphenidate treatment.

The team concluded, “for all-cause fractures, the results of the … within-individual comparison demonstrated that the use of methylphenidate is associated with lower risk … compared with the … period before the treatment initiation.”

Combined meta-analysis and nationwide population study indicates ADHD by itself has negligible effect on risk of type 2 diabetes

Study Indicates ADHD By Itself Has Negligible Effect on Risk of Type 2 Diabetes

Noting that “evidence on the association between ADHD and a physical condition associated with obesity, namely type 2 diabetes mellitus (T2D), is sparse and has not been meta-analysed yet,” a European study team performed a systematic search of the peer-reviewed medical literature followed by a meta-analysis, and then a nationwide population study.

Noting that “evidence on the association between ADHD and a physical condition associated with obesity, namely type 2 diabetes mellitus (T2D), is sparse and has not been meta-analysed yet,” a European study team performed a systematic search of the peer-reviewed medical literature followed by a meta-analysis, and then a nationwide population study.

Unlike type 1 diabetes, which is an auto-immune disease, type 2 diabetes is believed to be primarily related to lifestyle, associated with insufficient exercise, overconsumption of highly processed foods, and especially with large amounts of refined sugar. This leads to insulin resistance and excessively high blood glucose levels that damage the body and greatly lower life expectancy.

Because difficulty with impulse control is a symptom of ADHD, one might hypothesize that individuals with ADHD would be more likely to develop type-2 diabetes. 

The meta-analysis of four cohort studies encompassing more than 5.7 million persons of all ages spread over three continents (in the U.S., Taiwan, and Sweden) seemed to point in that direction. It found that individuals with ADHD had more than twice the odds of developing type 2 diabetes than normally developing peers. There was no sign of publication bias, but between-study variability (heterogeneity) was moderately high.

The nationwide population study of over 4.2 million Swedish adults came up with the same result when adjusting only for sex and birth year. 

Within the Swedish cohort there were 1.3 million families with at least two full siblings. Comparisons among siblings with and without ADHD again showed those with ADHD having more than twice the odds of developing type 2 diabetes. That indicated there was little in the way of familial confounding.

However, further adjusting for education, psychiatric comorbidity, and antipsychotic drugs dropped those higher odds among those with ADHD in the overall population to negligible (13% higher) and barely significant levels. 

The drops were particularly pronounced for psychiatric comorbidities, especially anxiety, depression, and substance use disorders, all of which had equal impacts.

The authors concluded, “This study revealed a significant association between ADHD and T2D [type 2 diabetes] that was largely due to psychiatric comorbidities, in particular SUD [substance use disorders], depression, and anxiety. Our findings suggest that clinicians need to be aware of the increased risk of developing T2D in individuals with ADHD and that psychiatric comorbidities may be the main driver of this association. Appropriate identification and treatment of these psychiatric comorbidities may reduce the risk for developing T2D in ADHD, together with efforts to intervene on other modifiable T2D risk factors (e.g., unhealthy lifestyle habits and use of antipsychotics, which are common in ADHD), and to devise individual programs to increase physical activity. Considering the significant economic burden of ADHD and T2D, a better understanding of this relationship is essential for targeted interventions or prevention programs with the potential for a positive impact on both public health and the lives of persons living with ADHD.”

Norwegian nationwide population study finds no association between maternal organophosphate pesticide exposure and offspring ADHD

Population Study Finds No Association Between Maternal Organophosphate Exposure and Offspring ADHD

Organophosphate pesticides were originally developed as nerve agents for chemical warfare, then used in lower doses as insecticides.

Organophosphate pesticides were originally developed as nerve agents for chemical warfare, then used in lower doses as insecticides. 

Their neurotoxicity raises the possibility of effects on development of the nervous system at lower doses, including psychiatric disorders.

Previous studies have found mixed results for any association with ADHD.

Norway has a single-payer health insurance system that covers virtually the entire population, facilitating nationwide population studies. 

A primarily Norwegian study team used the Norwegian Mother, Father, and Child Cohort Study, a prospective population-based cohort that enrolled participants between 1999 and 2008 to explore possible associations. The study invited all 227,702 pregnant mothers to enroll, of which 112,908 (41%) actually enrolled.

Children were eligible for the present study if they were born after 2002, did not have Down’s syndrome or cerebral palsy, had available maternal biospecimens, were the result of a singleton pregnancy, and lived near Oslo (the location of the clinic). That left a sample of 24,035.

The team used the Norwegian Patient Registry (NPR) to identify diagnosed cases of ADHD. 

From the final eligible population, the team randomly selected 552 mother-child pairs to represent the exposure distribution in the population of pregnancies that gave rise to the cases of ADHD.

At about 17 weeks into pregnancy, maternal spot urine samples were collected at the mother’s first ultrasound appointment. These samples were then tested for concentrations of organophosphate metabolites (breakdown chemicals). 

Adjustments were made for a variety of possible confounding variables: season, birth year, maternal education, vegetable intake, fruit intake, maternal self-reported ADHD, financial status, other organophosphorus pesticides, and sex.

Comparing higher versus lower maternal exposures to organophosphates, no significant differences emerged in rates of ADHD diagnosis among offspring.

Nationwide population study finds lisdexamphetamine is associated with significantly lower risk of hospitalization and death among persons with methamphetamine and amphetamine use disorders

Nationwide Population Study Finds Lisdexamphetamine is Associated with Significantly Lower Risk of Hospitalization and Death Among Persons with Methamphetamine and Amphetamine Use Disorders

Unprescribed amphetamines are the second most commonly used illicit drugs worldwide. Persons with methamphetamine or amphetamine use disorders (MAUD) have elevated rates of mortality, primarily from acute poisoning, but also from suicide, homicide, cardiovascular disease, and injuries.

Unprescribed amphetamines are the second most commonly used illicit drugs worldwide. Persons with methamphetamine or amphetamine use disorders (MAUD) have elevated rates of mortality, primarily from acute poisoning, but also from suicide, homicide, cardiovascular disease, and injuries. Illicit amphetamine use is also associated with aggressive behavior and criminality.

There are presently no approved pharmacological interventions for treating MAUD. 

A Finnish study team used the Swedish national registers to explore relationships between various drug treatments, including ADHD medications, and hard outcomes – hospitalization and death – among persons with MAUD.

The team looked at all Swedish residents aged 16 to 64 years with a registered first-time treatment contact due to MAUD between July 1, 2006 and December 31, 2018. They matched this cohort with data from the Prescribed Drug Register from July 2005 to December 2018.

They adjusted for the following confounding variables: age, sex, education, granted disability pension, long-term sickness absence during previous year (more than 90 days), and medication-related comorbidities.

The cohort consisted of 13,965 persons diagnosed with MAUD. Of these, 11,492 (about three out of four) were either hospitalized (10,341) or died (1,151) in the follow-up period.

The study looked at a variety of prescription drugs, including six ADHD medications: methylphenidate, atomoxetine, modafinil, amphetamine, dexamphetamine, and lisdexamphetamine. Prescriptions for none of these were significantly associated with higher risk of hospitalization or death from substance used disorder.

On the other hand, persons diagnosed with MAUD but prescribed lisdexamphetamine were in all instances at significantly lower risk. Lisdexamphetamine users were 18% less likely to be hospitalized for substance use disorder in within-individual and 25% less likely to be hospitalized in between-individual analyses. Lisdexamphetamine users also had half the risk of all-cause mortality

The authors concluded, “In this Swedish nationwide cohort study, use of lisdexamphetamine was consistently associated with a reduction in risk of death and hospitalization in persons with amphetamine or methamphetamine. Use of antidepressants were associated with an increase in risk of hospitalization due to SUD and any hospitalization or death. Benzodiazepine use was associated with poor outcomes.”

Nationwide population study finds cancer survivors have much higher risk of ADHD

Nationwide Population Study Finds Cancer Survivors Have Much Higher Risk of ADHD

Thanks to improvements in cancer treatment, there is a growing population of childhood and adolescent cancer survivors (CACSs). CACSs are at an increased risk of chronic physical, psychological, and social problems because of their cancer experiences and intensive cancer treatments.

Thanks to improvements in cancer treatment, there is a growing population of childhood and adolescent cancer survivors (CACSs). CACSs are at an increased risk of chronic physical, psychological, and social problems because of their cancer experiences and intensive cancer treatments. These include depression, anxiety, suicidal ideation, and post-traumatic stress disorder (PTSD). 

To what extent, if at all, does this also apply to ADHD? Noting that “previous studies … have reported inconsistent findings,” a local research team took advantage of Taiwan’s mandatory single-payer National Health Insurance that covers over 99% of the island’s population. More specifically, the National Health Insurance Research Database (NHIRD) maintains data on the insured population available on formal request for study purposes.

Linking the catastrophic illness database, mental disorders database, and longitudinal health insurance database, they tracked children age younger than 10 years and adolescents aged 11-17 years who were diagnosed with any malignancy (cancer) between 2002 and 2011 with no history of major psychiatric disorders (including ADHD). Parental history of major psychiatric disorders was likewise controlled as a potential confounder.

The team identified 5,121 CACSs, which they matched one to ten with 51,210 age-, sex-, income-, and residence-matched cancer-free controls.

ADHD diagnoses were made by board-certified psychiatrists during the study follow-up period (from enrollment through 2011) based on a comprehensive clinical interview and clinical judgment. 

Cancer survivors were diagnosed with ADHD at more than six times the rate of matched controls. Survival duration made no significant difference in this outcome. 

Cancers of bone, connective tissue, skin, and breast were associated with a more than threefold increase in risk of an ADHD diagnosis. For cancers of the circulatory system, there was a more than sixfold increased risk of ADHD, and for those of the genitourinary organs, more than sevenfold increased risk. 

For brain cancer survivors, the increased risk of ADHD was more than twelvefold. That may be at least in part because the brain itself was targeted for treatment in these instances, which plausibly could cause damage resulting in psychiatric disorders.

The team concluded, “we observed a comparatively higher risk of MPDs [major psychiatric disorders] among CACSs than among controls and likewise found that such risks varied across different cancer types. Survivors of both CNS [central nervous system] and non-CNS cancers have increased risks of MPD diagnoses. Among the enrolled CACSs, ASD [autism spectrum disorder] and ADHD were associated with most types/categories of cancers. Long-term care of this vulnerable population must include psychosocial interventions for patients and their families. Physicians need to be aware of early signs of mental health problems in this high-risk subpopulation and arrange early interventions accordingly.”

Meta-analysis suggests regular exercise improves core symptoms and executive functions in child and adolescent ADHD

Meta-analysis Suggests Regular Exercise Improves Core Symptoms and Executive Functions in Child and Adolescent ADHD

A Chinese study team has performed an updated meta-analysis of randomized clinical trials (RCTs) published through July 2022, looking specifically at the effects of chronic exercise on ADHD core symptoms and executive functions in children and adolescents.

A Chinese study team has performed an updated meta-analysis of randomized clinical trials (RCTs) published through July 2022, looking specifically at the effects of chronic exercise on ADHD core symptoms and executive functions in children and adolescents.

The researchers defined chronic to mean exercise interventions lasting at least six weeks, with the longest clocking in at well over a year (72 weeks). 

They only included RCTs with blinding of all assessors who measured the primary outcomes, to guard against any conscious or unconscious bias.

A total of 22 studies met criteria for inclusion in the series of meta-analyses they performed. The RCTs were widely distributed, with four from North America, three from Africa, three from Europe, eleven from Asia, and one from Oceania.

Three studies were rated as being at low risk of bias, the other 19 at moderate risk of bias.

Meta-analysis of eleven RCTs with a combined 514 participants reported a small-to-medium reduction in ADHD core symptoms. Between-study variation (heterogeneity) was moderate, and there was no indication of publication bias.

Breaking that down by age group, for children (eight RCTs, 357 children) the reduction in core symptoms was likewise small-to-medium, versus a medium effect size reduction among adolescents (three RCTs, 157 adolescents), with no heterogeneity.

When the control group received no treatment or was sedentary (8 RCTs, 422 participants), the effect size remained small-to-medium, whereas when the control group received education, it became large (two RCTs, 58 participants). 

Improvements in executive functions were even more pronounced. Meta-analysis of 17 RCTs with a combined 795 participants yielded a medium-to-large effect size reduction in executive functions overall. Heterogeneity was moderate, with absolutely no sign of publication bias.

More specifically, there was a medium effect size improvement in working memory (10 RCTs, 290 participants), a medium-to-large effect size improvement in cognitive flexibility (8 RCTs, 206 participants), and a large effect size improvement in inhibition (12 RCTs, 299 participants). 

Once again, adolescents benefited more than children. Whereas children showed medium effect size improvements in executive function (14 RCTs, 659 children), adolescents registered enormous improvements (3 RCTs, 136 adolescents).

One note of caution, though. Among RCTs rated low risk of bias, effect size improvements in both ADHD core symptoms (3 RCTs, 180 participants) and executive functions (2 RCTs, 86 participants) were small and did not reach statistical significance. That suggests a need for more and better RCTs to reach a more settled verdict.

For now, the authors concluded, “This meta-analysis suggests that CEIs [chronic exercise interventions] have small-to-moderate effects on overall core symptoms and executive functions in children and adolescents with ADHD.”

Meta-analysis reports weak evidence for mindfulness interventions for children and adolescents with ADHD

Meta-analysis Reports Weak Evidence for Mindfulness Interventions for Children and Adolescents with ADHD

Mindfulness involves focusing on the present moment. Mindfulness meditations include choosing a point of focus, such as breathing, and focusing on it continuously. They may also involve focusing single-mindedly on body movements, as in Yoga.

Mindfulness involves focusing on the present moment. Mindfulness meditations include choosing a point of focus, such as breathing, and focusing on it continuously. They may also involve focusing single-mindedly on body movements, as in Yoga. This could be potentially useful because in focusing on the present moment with attention and emotion regulation, it addresses regulatory capacities impaired in ADHD.

Previous studies of efficacy of mindfulness interventions have been inconclusive, limited by low methodological quality. A Taiwanese study team tried to remedy this with a fresh meta-analysis of randomized controlled trials (RCTs).

The team included three types of RCTs: yoga intervention, mindfulness-based psychological intervention, and mediation training. There was a lot of variation in the length of individual sessions and in the total number of hours of intervention.

Five studies used a waiting list control group. Two studies used treatment as usual or standard care as control groups. Only four studies followed best practices of using an active control group, such as a listening task, behavioral therapy, cooperative activities, or an emotional education program.

Twelve studies scored between 4 and 7 points from a possible total of 10 points, suggesting at best moderate methodological quality. More seriously, there was no indication of patient and therapist blinding.

With all these limitations, the one nominally positive result was for improvement in ADHD symptoms. A meta-analysis of seven RCTs with a combined 184 participants found a large reduction in ADHD symptoms post-treatment that did not persist at follow-up a couple months later. But between-study variation (heterogeneity) was extreme, with evidence of publication bias. The authors did not offer a revised estimate of efficacy based on the standard trim-and-fill adjustment.

Two additional meta-analyses, of seven RCTs with 200 participants, and seven RCTs with 215 participants, found no improvement in either externalizing or internalizing behaviors post-treatment. This time there was no sign of publication bias in either case. For externalizing behaviors, there was negligible heterogeneity, and moderate heterogeneity for internalizing behaviors.

A meta-analysis of four RCTs combining 122 participants found a moderate improvement in child mindfulness post-treatment, but it was not statistically significant.

Nationwide population study suggests ADHD medication may reduce child abuse

Nationwide Population Study Suggests ADHD Medication May Reduce Child Abuse

Child abuse includes any of the following inflicted on a minor under 18 years old: physical or emotional harm, sexual abuse, or neglect.

Child abuse includes any of the following inflicted on a minor under 18 years old: physical or emotional harm, sexual abuse, or neglect.

It is known to be associated with environmental factors such as poverty, parents or neighbors with a history of violence, and gender inequality.

Chronic mental disorders in minors are also associated with child abuse. To what extent, if any, might that be true of ADHD?

Taiwan has a single-payer national health insurance system that covers more than 99.6% of all residents, enabling nationwide population studies.

A local research team used data from almost two million Taiwanese in their country’s National Health Insurance Research Database (NHIRD) spanning 15 years (2000-2015) to carry out a matched-cohort study. 

All diagnoses of ADHD were made by board-certified specialists such as psychiatrists, pediatricians, neurologists, or physiatrists with a specialty in child and adolescent development.

3,540 children and adolescents between 6 and 18 years old with a diagnosis of ADHD were matched on a one-to-three basis with 10,620 peers from the NHIRD without an ADHD diagnosis.

The team adjusted for age, gender, location of residence (Northern, Central, Southern, and Eastern Taiwan), urbanization level of residence, level of hospitals as medical centers, and monthly insured premium. They further adjusted for comorbid conditions: intellectual disability, autistic disorder/pervasive developmental disorder, conduct disorder (CD)/oppositional defiant disorder (ODD), other developmental disorders, childhood emotional disorder, Tourette syndrome/tics disorders, and involuntary urination and defecation.

Overall, children and adolescents with an ADHD diagnosis were 1.8 times as likely to be abused as those without an ADHD diagnosis.

Unmedicated children and adolescents with an ADHD diagnosis were three times more likely to be abused. ADHD medication cut that risk in half.

That held true whether the medication used was methylphenidate or atomoxetine. Methylphenidate appeared to be slightly more effective than atomoxetine, and the combination of methylphenidate and atomoxetine slightly more effective yet, but these differences were not statistically significant.

The team concluded, “The results support that pharmacotherapy may attenuate the risk of child abuse in ADHD patients.”

Meta-analysis indicates physical activity interventions lead to major improvements in motor proficiency in children and adolescents with ADHD

Meta-analysis Indicates Physical Activity Lead to Major Improvements in Motor Proficiency in Children with ADHD

The three primary symptoms of ADHD are inattention, hyperactivity, and impulsivity, which can significantly limit personal, social, academic, or occupational functioning.

The three primary symptoms of ADHD are inattention, hyperactivity, and impulsivity, which can significantly limit personal, social, academic, or occupational functioning. 

In addition to these symptoms, between a third and a half of children and adolescents with ADHD have limited motor proficiency. They are less coordinated or skilled in performing motor tasks than their peers. This in turn reduces their participation in physical activities. They are more likely to become overweight or obese. They are also more likely to have difficulty socializing with peers.

Current ADHD medications are effective at treating the primary symptoms of ADHD, but have no known effect on impaired motor proficiency. 

Noting that “physical activity interventions are relatively easy to implement and have been shown to improve motor proficiency compared to other behavioral therapies,” a joint Chinese and American study team set out to explore effect sizes through a systematic review of the peer-reviewed medical literature.

They identified ten studies with a total of 413 participants suitable for meta-analysis. Overall, physical activity interventions led to very large effect size improvements in motor proficiency. There was no sign of publication bias, but considerable variation (heterogeneity) between studies.

To address this heterogeneity, the team next investigated how different types of physical activity intervention affected outcomes. Those that concentrated on body coordination, fine motor control (manual dexterity, using the small muscles in our hands and wrists), and object control (moving or receiving an object such as a ball with accuracy) were found to be responsible for the large effect size improvements in motor proficiency, this time with low heterogeneity.

By contrast, strength and agility training and locomotor training (such as walking, running, hopping, skipping) were associated with smaller effect size improvements that were no longer significant, and continued to vary significantly between studies.

Despite combining ten separate studies, sample sizes remained small, even more so when broken down by type of physical activity intervention. Strength and agility interventions were associated with a medium-to-large effect size improvement, but with only four studies combining 131 participants, may simply have been under-powered to achieve significance. Similarly, locomotor interventions were associated with small-to-medium effect size improvement, but with only three studies and a total of 117 participants, may again have been under-powered. 

While these preliminary findings look promising, they will need additional studies and greater numbers of total participants to be confirmed.
