[Premature and usual periods of "rapid" sleep during attacks of diurnal narcolepsy].

The authors studied some psychophysiological characteristics of precocious and usual periods of rapid sleep in 17 patients with polysymptomatic narcolepsy during 92 attacks of day sleep. Precocious rapid sleep duffers from usual one in an inclusion into the dream content the experimental situations and their emotional saturation. The patients underestimated the duration of sleep and were unsatisfied by its quality. These differences indicate to a functional interconnection of rapid sleep with delta-sleep in the process of brain integration of information and assist to understand the pathogenesis of some traits of narcolepsy.
