Sleep research has underlined how sleep is a specific functional moment inserted in the more complex system of circadian psychobiological rhythms. Many experimental data have evidenced that in particular REM sleep is involved in information processing and cognitive processes. The authors examine correlations between daytime cognitive performances and sleep patterns in a group of 11 schizophrenic patients, and in a control group made of 11 non-schizophrenic (borderline, depressed, character disorders) patients. Results show that there exists a relationship between REM sleep and cognitive activities, beyond nosographic partitions. They on the other side suggest caution in using sleep as a means of discrimination between schizophrenic and non-schizophrenic patients.
