SUMMAR Y The aim of the study was to characterize the sleep pattern in children with attention deficit/hyperactivity disorder (ADHD). By means of polysomnography (PSG), sleep patterns were studied in 17 unmedicated preadolescent boys rigorously diagnosed with ADHD and 17 control boys precisely matched for age and intelligence. Although ADHD children did not display a general sleep alteration, major PSG data showed a significant increase in the duration of the absolute rapid eye movement (REM) sleep and the number of sleep cycles in ADHD group when compared with controls. In addition, REM sleep latency tended to be shorter in ADHD children. These results suggest that in ADHD children, a forced REM sleep initiation may produce a higher incidence of sleep cycles and may also contribute to an increased duration of the absolute REM sleep. The overall pattern of the findings implies that a forced ultradian cycling appears characteristic for the sleep in ADHD children, which may be related to alterations of brain monoamines and cortical inhibitory control accompanying the ADHD psychopathology.k e y w o r d s attention deficit/hyperactivity disorder children, brain monoamines, cortical inhibition, rapid eye movement sleep, ultradian cycling
Praktische Pädiatrie TS und HKS Bei beiden psychiatrischen Störungen -sowohl dem Gilles-de-la-TouretteSyndrom (TS) als auch dem hyperkinetischen Syndrom (HKS) -liegt eine mangelnde inhibitorische Kontrolle zentralnervöser motorischer Aktivierungsmuster vor. Diese ist für den aktuellen Alltag und die zukünftige seelische Entwicklung des betroffenen Kindes höchst belastend, insbesondere wenn beide Störungen im Sinn einer Komorbidität gemeinsam auftreten. Daneben finden sich bei beiden Krankheitsbildern Beobachtungen, dass sich die Störungen der zentralnervösen motorischen Kontrolle in den Schlaf hinein fortsetzen können. Dies spiegelt sich in einer veränderten Schlafstruktur, vermehrtem Bewegen im Schlaf, Insomnien (Ein-und/oder Durchschlafstörungen) sowie Parasomnien (spezifische, unerwünschte Ereignisse im Schlaf wie z. B. Schlafwandeln) wider.
