title: Sleep disorders and depression: the 'chicken and egg' situation.
abstract: The question of whether sleep disorders are part of the clinical picture of depression or of its aetiology remains unanswered. Still, clinical observation in general, polysomnographic studies and the observed antidepressant effect of sleep deprivation, clearly indicate the intimate relationship between sleep disturbances and depression.
