IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Objectives: Primary headache syndromes (eg, migraine and tension-type headache [TTH]) and attention-deficit/hyperactivity disorder (ADHD) are prevalent in childhood and may cause impairment in social and academic functioning. We tested if ADHD or its symptoms are associated with specific headache syndromes or with headache frequency. Study design: Cross-sectional epidemiological study with direct interviews to parents and teachers using validated and standardized questionnaires. Setting: Populational study. Participants: Children aged 5 to 11 years (n = 1856). Outcome measures: Prevalence of ADHD as a function of headache status in crude and adjusted analyses. Results: The prevalence of migraine was 3.76%. Infrequent episodic TTH occurred in 2.3% of the sample, and frequent episodic TTH occurred in 1.6%. The prevalence of ADHD was 6.1%. The prevalence of ADHD was not significantly different by headache category. For hyperactivity-impulsivity symptoms, the prevalence was 8.1% in children without headache, 23.7% in children with migraine (relative risk [RR], 2.6; 95% confidence interval [CI], 1.6-4.2), and 18.4% in children with probable migraine (RR, 2.1; 95% CI, 1.4-3.2). For inattention, no significant differences were seen. In multivariate analyses, ADHD or inattention symptoms were not predicted by headache subtypes or headache frequency. Hyperactivity-impulsivity symptoms were significantly associated with any headache (P < 0.01), TTH (P < 0.01), or migraine (P < 0.001). Conclusion: Migraine and TTH are not comorbid to ADHD overall, but are comorbid to hyperactive-impulsive behavior. Providers and educators should be aware of the association.
