Abstract
Evidence for the importance of delta sleep is reviewed, and the hypothesis tested that marked deficits in these sleep stages are characteristic of chronic schizophrenics. The sleep patterns of 9 chronic schizophrenics were monitored for 8 consecutive nights by means of continuous all-night EEG, eye and chin-muscle recordings. The main finding was that all Ss showed dramatic and stable deficits in delta sleep stages 3 and 4. The role of factors other than chronic schizophrenia producing this finding is discussed.Keywords
