Sleep deprivation in depressed adolescents and psychiatric controls

Abstract

Up to 70% of depressed adults have an antidepressant response to sleep deprivation. To study the effects of sleep deprivation on depression severity and level of arousal in psychiatrically disturbed adolescents, we deprived 17 patients of sleep for 36 hours. Severity of depression and subjective arousal were assessed at baseline, during sleep deprivation, and after 1 night's recovery sleep. We found that severely depressed adolescents showed a significant decrease in depression severity, whereas depressed patients in remission and psychiatric controls worsened after sleep deprivation. Patients with depression in remission showed a significant decrease in subjective arousal after sleep deprivation. In contrast to findings in depressed adults, the effects of sleep deprivation persisted after 1 night of recovery sleep, and diurnal variation of mood did not predict response to sleep deprivation. These findings are consistent with those reported in the adult literature, and suggest a common psychophysiology between adult and adolescent depression.
