Abstract
The sleep pattern of 13 prepubertal children, nonmedicated, rigourously diagnosed as Attention Deficit Disorder (ADD) was recorded for two consecutive nights. Analyses of sleep pattern variables revealed a marked reduction of sleep onset latency (p less than .01), a great number of nocturnal awakenings (p less than .01), and a high increase of Delta sleep percentage (p less than .01) for the ADD children compared to normals. In addition, the two subtypes of the disorder--ADD with hyperactivity (ADD/H) and ADD without hyperactivity (ADD/WO) or ADD undifferentiated--showed distinct hypnopolygraphic correlates. Those ADD/H children had a greater sleep fragmentation and a lesser degree of sleep efficiency. These findings would support the hypothesis that ADD is related to a deficient control of arousal level and, on the other hand, suggest that ADD/H and ADD/WO are different clinical entities.

The narcoleptics had stage 1 rapid eye movement (REM) periods at sleep onset rather than approximately 90 min after sleep onset as most subjects do, interpreted as suggesting that narcoLEptics are susceptible to “precocious triggering” of the pontine reticular formation.

The two ADDH groups resembled each other but the addition of Conduct Disorder brought greater social disability and more adverse family environments.

The few studies that have compared Attention Deficit with Hyperactivity with Conduct Disorder with or without Anxiety Disorder suggest that ADDH may be a cognitive disorder, possibly of neurodevelopmental origin; Conduct Disorder one of social relationships of psychosocial origin; and Anxiety Disorder less predominantly male, associated with parental anxiety, and less severe than the other two.

In a series of three studies, sleep problems were investigated in preschool-aged children with attention deficit disorder relative to control children without the disorder, and it was demonstrated clearly that parents of hyperactive children considered their children to have many more sleep problems than did parents of the control children.

Results suggested that no simple level of arousal hypothesis can account for the behavior patterns of hyperkinetic children and thatlevel of arousal is not a particularly useful predictor of drug responding in these children.

Electroencephalographic sleep patterns in children with minimal brain dysfunction syndrome (MBDS or hyperkinesis) before and during stimulant treatment differed little from those of age-matched controls, suggesting that the therapeutic mechanisms of amphetamines in MBDS are unlikely to be exerted on or reflected in physiological sleep patterns.
