[Night sleep study in acute and chronic psychosis (author's transl)]. 1980

R Julien, and E Balzamo, and H Dufour, and J Bert

A group of 22 psychotics (19 schizophrenics) was recorded in acute and/or chronic phase by series of 3 consecutive nights. Our main purposes were to study correlations between subgroups and sleep patterns and to follow the clinical evolution of these patients in looking at the quantitative and/or qualitative modifications of the various sleep states. Schizoaffective psychotics showed a lack of the "first night effect". The patients recorded in acute and in remission phases differ from unmedicated normal subjects: the former had less deep sleep and more "intermediate phases": the later presented an increase, sometimes very high, of REM total duration. Finally, within each subgroup, the analysis of individuals pointed out, for some of them, an evolution opposite to the general tendency.
