Key symptoms of major depressive disorder are psycho motor disturbances. For example, body movements, reaction time, and speech may be so slowed that some depressed people seem to be doing everything in slow motion. Others experience the opposite extreme and are constantly moving and fidgeting, wringing their hands, and pacing. Depression can be so severe that people develop delusions or hallucinations, which are symptoms of psychotic depression. The more deeply a person descends into depression over an extended period, the more she or he withdraws from social activities.
