The sleep therapies of depression

Abstract

This paper reviews five different types of deliberate sleep-wake manipulations which are reported to have antidepressant effects: total sleep deprivation, partial sleep deprivation, a phase advance of the sleep periods, and REM deprivation. The effects of total sleep deprivation are best documented. Of 852 depressed patients studied, 493 or 57.9% improved following sleep deprivation. The REM deprivation procedure acts more slowly, but is of more lasting clinical value than the other forms. Partial sleep deprivation during the second half of the night may be as good as total sleep deprivation and better tolerated. The findings are reviewed in terms of psychological, neurophysiological, biochemical, and chronobiological perspectives.
