Recent evidence has been accumulating that the sleep of individuals with attention deficit hyperactivity disorder (ADHD) is not only disrupted in a nonspecific way but that ADHD has an increased association with simple sleep related movement disorders such as restless legs syndrome/periodic limb movements in sleep (RLS/PLMS), rhythmic movement disorder (body rocking and head banging), and parasomnias, such as disorders of partial arousal (sleep walking, sleep terrors, and confusional arousals). In addition increased associations have been reported between ADHD and hypersomnias such as narcolepsy and sleep apnea as well as circadian rhythm disorders, such as delayed sleep phase syndrome. These relationships are reviewed and the implications for such associations are explored. Patients with sleep disorders should be queried about the symptoms of ADHD and vice versa.

Subjects using opioids on a chronic basis have been reported to have a high prevalence of abnormal sleep architecture and central sleep apnea (CSA). The severity of CSA is, in part, related to blood opioid concentration. The aim of this study was to investigate subjective daytime sleepiness and daytime function in patients who are on stable methadone maintenance treatment (MMT) and to assess the possible mechanisms involving abnormal sleep architecture, CSA severity, and blood methadone concentration. ⋯ Patients on stable MMT have, in general, normal subjective daytime sleepiness but impaired daytime function that partially relates to depression. The changes in sleep architecture, presence of CSA, and blood methadone concentrations do not significantly affect subjective daytime sleepiness and daytime function in these patients.

To evaluate the health-related quality life (HRQOL) of drug-naïve patients with narcolepsy with cataplexy (NAwith CA), narcolepsy without cataplexy (NA without CA) and idiopathic hypersomnia without long sleep time (IHS without LST), and to explore the factors influencing the HRQOL. Factors associated with the occurrence of automobile accidents are also discussed. ⋯ Our results indicated that HRQOL decreases in drug-naïve patients with hypersomnia, but neither disease category nor severity of the disorder appears as an associated factor. Increased severity of hypersomnia, however, was thought to play an important role in the occurrence of automobile accidents.
