Abstract	The study reports psychiatric and sleep EEG observations after 264 hours of sleep deprivation in a normal, 17-year-old, white boy. Our subject developed some behavioral changes frequently reported as characteristic of sleep deprivation, but the so-called psychosis of sleep deprivation did not develop. Several possible reasons for the maintenance of ego functions despite the severe stress of prolonged wakefulness are discussed. Sleep EEG data from three recovery sleep nights and from three postrecovery nights are presented. There was a marked increase in REM sleep during the recovery nights comparable to the increases seen in REM deprivation studies. The increase seen in Stage 4 sleep during the recovery nights was no greater than has been observed after 100 hours of wakefulness. These data do not support the idea that the deprivation of Stage 4 sleep is cumulative as is the deprivation of REM sleep. The data indicate that prolonged sleep deprivation does not necessarily result in psychosis. However, other behavioral changes noted during prolonged wakefulness may be specifically associated with either REM or NREM deprivation, and some possible mechanisms regarding this specificity are outlined.
