Meta-analysis Finds Certain ADHD Meds Associated with Headaches, But Others Are Not

An international study team has just reported findings from a series of meta-analyses exploring associations between ADHD medications and headaches in children and adolescents. 

First, to compare headache occurrence in individuals with ADHD to those without ADHD, the team performed a very large meta-analysis of twelve studies with over 2.7 million children and adolescents. Those with ADHD had twice the rate of headaches. 

There was no indication of publication bias, but there was considerable variation (heterogeneity) among studies, with crude odds ratios spanning from 0.9 to 3.37. Nevertheless, ten of the twelve studies pointed to higher odds among children and adolescents with ADHD. The four studies that controlled for age, sex, race, and other socioeconomic status variables reaffirmed the finding of a doubling of headache risk, this time with acceptable heterogeneity.

Three studies with a combined 7,755 participants found no difference in tension headaches, but five studies with over a quarter million persons found more than a doubling of the rate of migraine in children and adolescents with ADHD.

Next, the team performed meta-analyses of 58 randomized controlled trials (RCTs) of specific ADHD medications that met eligibility criteria for their systematic review. Because only a single eligible RCT apiece looked at bupropion and clonidine, these ADHD medications could not be included in the meta-analyses.

A meta-analysis of ten RCTs with a total of 2,672 participants found absolutely no association between use of amphetamines (including lisdexamphetamine) and headaches. Variation (heterogeneity) between studies was minimal, and there was no sign of publication bias.

A smaller meta-analysis of six RCTs with a combined 818 participants found a 24% increase in headaches among modafinil users, but it was not statistically significant, perhaps because of the much smaller combined sample size.

A meta-analysis of 17 RCTs with a total of 3,371 participants found a 33% increase in headache occurrence among methylphenidate users over placebo. Between-study variation (heterogeneity) was negligible, and there was absolutely no sign of publication bias. 

Similarly, a meta-analysis of 22 RCTs with a combined 3,857 participants reported a 29% increase in headache occurrence among atomoxetine users over placebo. Again, heterogeneity between studies was negligible, with absolutely no indication of publication bias.

Finally, a meta-analysis of eight RCTs with 1,956 participants found a 43% increase in headache occurrence among guanfacine users over placebo. Once again, with negligible heterogeneity and no indication of publication bias.

NEWS TUESDAY: Decision-making and ADHD: A Neuroeconomic Perspective

The Neuroeconomic Perspective 

Neuroeconomics combines neuroscience, psychology, and economics to understand how people make decisions. Neuroeconomic studies suggest that brain regions responsible for evaluating risk and reward, including the prefrontal cortex and dopamine pathways, function differently in individuals with ADHD. These insights are crucial for developing more tailored interventions. For example, understanding how ADHD affects reward processing might inform strategies that help individuals resist impulsive choices or increase motivation for delayed rewards.

Understanding Decision-Making in ADHD 

We know that decision-making is a sophisticated process involving various cognitive procedures. It’s not just about choosing between options but also about how to weigh risks, rewards, and potential future outcomes; Attention, motivation, and cognitive control are core to this process. For individuals with ADHD, however, this neural framework is affected by impairments in attention and impulse control, often resulting in “delay discounting”—the tendency to prefer smaller, immediate rewards over larger, delayed ones.

This propensity for impulsive decisions is more than a personal challenge; it has broader societal and economic implications. Previous studies have shown that these tendencies in ADHD can lead to issues in academics, work, finances, and personal relationships, emphasizing the need for targeted support and interventions.

Implications and Future Directions 

This review highlights a need for continued research to bridge the gaps in understanding how ADHD-specific cognitive deficits influence decision-making. Viewing ADHD through a neuroeconomic lens clarifies how cognitive and neural differences affect decision-making, often leading to impulsive choices with economic and social impacts. This perspective opens doors to more effective interventions, improving decision-making for individuals with ADHD. Future policies informed by this approach could enhance support and reduce associated societal costs.

Exploring the Link Between ADHD and Student-Teacher Relationships: A Meta-Analysis

Children with ADHD face significant challenges in academic and social settings, often including difficult interactions with teachers. This meta-analysis investigates the quality of student-teacher relationships for children with ADHD, focusing on two key dimensions: closeness and conflict. By synthesizing data from 27 studies encompassing 17,236 participants, the study aims to provide a comprehensive understanding of these dynamics and inform interventions to support both students and teachers.

Methods

A systematic review was conducted using databases such as PsycInfo, ERIC, and ProQuest. Researchers identified 47 effect sizes from 27 studies, examining the association between ADHD symptoms and the quality of student-teacher relationships. Relationship quality was assessed through two primary dimensions:

  1. Closeness – Warmth, positivity, and openness between the student and teacher.
  2. Conflict – Hostility, negativity, and tension in interactions.

Eight moderator analyses were also performed to explore how factors like grade level, gender, ADHD presentation, and comorbid conditions influenced these relationships.

Summary

The findings reveal that children with ADHD symptoms typically experience relationships with teachers characterized by lower levels of closeness and higher levels of conflict. Notably, externalizing behaviors such as hyperactivity and impulsivity are more strongly associated with conflict than inattentive symptoms. Moderator analyses showed that factors like gender, ADHD presentation, and age influence the severity of these relationship dynamics. For instance, younger children and those with hyperactive-impulsive presentations tend to have higher conflict levels with teachers.

Additionally, the research emphasizes the reciprocal nature of these relationships: ADHD symptoms may exacerbate teacher frustration, while negative teacher-student interactions can intensify student behavioral challenges.

Conclusion

This meta-analysis highlights the critical role of student-teacher relationships in the development of children with ADHD. The findings underline the need for targeted interventions that foster positive teacher-student interactions and reduce conflict. Addressing these relationship dynamics could enhance academic performance, social integration, and emotional well-being for children with ADHD. Future research should explore the causal pathways between ADHD symptoms and relationship quality to better inform educational strategies and support systems.

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.
