Sleep Patterns in Hyperkinetic and Normal Children

Abstract

Sleep patterns in nonmedicated hyperkinetic (n = 11) and normal control (n = 11) male children (8-12 years old) were compared to document possible sleep disturbance in hyperkinetic children. Electroencephalographic, electro-oculographic, electromyographic, and autonomic measures were monitored continuously for five consecutive nights. Analysis of sleep pattern variables revealed a significantly longer rapid eye movement onset latency (p less than 0.05) and marginally significant greater absolute and relative amounts of movement time (p less than 0.07) for the hyperkinetic group relative to controls. No other sleep parameters differentiated the groups. It was concluded that baseline tonic sleep parameters do not indicate marked sleep disturbance in hyperkinesis. The results are discussed within the context of hypothesized arousal dysfunction underlying this disorder. Key Words: Hyperkinetic children--Hyperkinesis--NREM and REM sleep cycles--Spontaneous skin potential responses.
