Slow-wave Sleep Deprivation as a Possible Treatment for Major Depressive Disorder
Sleep deprivation can acutely reverse depressive symptoms in patients with major depression.
Although underlying mechanisms of the antidepressant action in sleep deprivation are unclear,
many of these observations can be explained by abnormal slow wave homeostasis. This study
will test the prediction that selectively reducing slow waves during sleep (slow wave
deprivation; SWD), without disrupting total sleep time, will yield an antidepressant effect.
