ADHD Is Comorbid to Migraine in Childhood: A Population-Based Study.

OBJECTIVE Recurrent headaches and ADHD are prevalent in the pediatric population. Herein, we assess if ADHD is comorbid to headaches overall, to headache subtypes (e.g., migraine), and to headache frequency. METHOD Informed consent and analyzable data were obtained for 5,671 children aged 5 to 12 years (65.9% of the target sample). Parents and teachers were interviewed using validated questionnaires based on the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). Relative risks were modeled using univariate and multivariate analyses. RESULTS As contrasted to nonheadache controls, the prevalence of ADHD was significantly higher in children with migraine ( p < .001) but not in those with tension-type headaches. In children with migraine, risk of ADHD increased as a function of headache frequency ( p < .05). CONCLUSION Migraine and frequent migraine are comorbid to ADHD. Future studies should focus on the impact of the association on the burden to the children and their families.
