Sleepiness in subjects with possible attention-deficit hyperactivity disorder

Ito et al. investigated the relationship between excessive daytime sleepiness (EDS) and attention deficit/hyperactivity disorder (ADHD) symptoms in adults with possible ADHD [1]. Compared with non-ADHD participants, participants with possible ADHD showed an evening chronotype, depressive symptoms, sleepiness and sleep disturbances. Hierarchical logistic regression analyses revealed that adjusted odds ratio (95% CI) of possible ADHD symptoms for EDS was 1.91 (1.59-2.29). Furthermore, the inattention score in relation to ADHD was significantly higher in the severe EDS group compared with the moderate and non-EDS groups.
