Abstract
In 10 children with deficits in attention, motor control and perception (DAMP), the relation between daytime vigilance and night-time sleep quality was examined with polygraphic sleep recordings, multiple sleep latency tests and measurements of reaction times. Two girls and eight boys, 6-12 years of age were studied. Eighteen normal children served as controls. Normal sleep regulation and sleep quality was found, but the children with DAMP tolerated the recording procedure less well than the controls. Most patients did not suffer from increased daytime sleepiness, but at MSLT 3, patients had short sleep latencies as in daytime hypersomnolence. Reaction times were significantly longer among the patients than among the controls. It is proposed that the findings may be related to functional changes in the forebrain.
