For simplification, symptoms and signs in psychiatry can be grouped into the following categories: • Abnormalities of behavior and movements. • Abnormalities of mood and emotion. • Abnormalities of speech. • Abnormalities of thinking. • Abnormalities of perception. • Abnormalities of awareness of self and others. • Abnormalities of consciousness. • Abnormalities of attention and concentration. • Abnormalities of memory. • Abnormality of judgment. • Abnormality of insight. • Abnormality of sleep, eating and sex. 2 ABNORMALITIES OF BEHAVIOR AND MOVEMENTS Very important to understand. 1. *Psychomotor Retardation: slowed mental and motor activities, the most common diagnosis are major depressive disorder. 2. *Stupor: a state in which a person, although is fully awake with open eyes, does not react to the surroundings: mute, immobile and unresponsive.
