Sleep and ADHD.

This paper, intended to provide useful insights for the clinical management of sleep disturbances in attention-deficit/hyperactivity disorder (ADHD), presents a critical, updated overview of the most relevant studies on the prevalence, etiopathophysiology and treatment strategies of sleep problems associated with ADHD, including restless legs syndrome, periodic limb movements in sleep, sleep-onset delay, increased nocturnal motor activity, sleep-disordered breathing, deficit in alertness, and sleep alterations accounted for by comorbid psychiatric disorders or ADHD medications. We also discuss some possible avenues for future research in the field.
