Insights
Obstructive Sleep Apnea (OSA) is common in children with Attention Deficit Hyperactivity Disorder (ADHD). Treating OSA, like with adenotonsillectomy, can improve ADHD symptoms, potentially reducing the need for long-term medication.
Area of Science:
- Pediatric Medicine
- Neurology
- Sleep Medicine
Background:
- Obstructive Sleep Apnea (OSA) and Attention Deficit Hyperactivity Disorder (ADHD) are prevalent in children.
- OSA exacerbates ADHD symptoms through hypoxia and sleep fragmentation.
- Treatments for OSA may improve ADHD symptoms.
Purpose of the Study:
- To conduct an updated systematic review and meta-analysis on the relationship between OSA and ADHD in children.
- To synthesize evidence on the prevalence and impact of OSA in pediatric ADHD.
- To evaluate treatment outcomes for OSA in children with ADHD.
Main Methods:
- Systematic search of PubMed, Embase, and SCOPUS for longitudinal studies.
- Data extraction and bias assessment using Newcastle-Ottawa Scale.
- Meta-analysis for pooled prevalence and descriptive review for other outcomes.
Main Results:
- Pooled prevalence of OSA in children with ADHD was 44%.
- Adenotonsillectomy for OSA significantly improved both OSA and ADHD symptoms.
- This suggests adenotonsillectomy may complement pharmacological ADHD therapy.
Conclusions:
- OSA and ADHD are closely related comorbid conditions in children.
- Clinicians should consider concurrent OSA evaluation in children with ADHD.
- This approach can guide treatment and potentially decrease reliance on long-term medication.
Background:
Obstructive Sleep Apnea (OSA) and Attention Deficit Hyperactivity Disorder (ADHD) are two relatively common conditions in the pediatric population, with multiple studies demonstrating a strong association between the two. Hypoxia and sleep fragmentation caused by OSA has been shown to exacerbate ADHD symptoms, while treatment for OSA, such as with continuous positive airway pressure or adenotonsillectomy, may improve ADHD symptoms. We aim to provide an updated systematic review and meta-analysis on the complex relationship between OSA and ADHD in children.
Methods:
PubMed, Embase, and SCOPUS were searched from inception to 1 December 2024 for longitudinal studies investigating the association between OSA and ADHD in children. Two independent authors selected relevant articles, extracted data, assessed bias using the Newcastle-Ottawa Scale and evaluated quality of evidence following the Grading of Recommendations, Assessment, Development and Evaluations framework. Random-effects meta-analysis was performed to synthesize pooled prevalence, while descriptive reviews were performed for all other outcomes.
Results:
This systematic review and meta-analysis of 11 studies and 903 children formally diagnosed with OSA or ADHD found that the pooled prevalence of OSA in children with ADHD was 44% ( 95% CI [2%, 56%]). Descriptive analysis found that adenotonsillectomy for OSA consistently led to significant improvements in both OSA and ADHD symptoms, suggesting its potential in complementing existing pharmacological therapy in improving ADHD symptoms.
Conclusion:
OSA and ADHD are closely related comorbid conditions. Physicians should be cognizant of this association and consider concurrent evaluation for OSA in children with ADHD symptoms, which can effectively guide treatment strategies and potentially reduce the need for long-term pharmacological treatment.
