Apathy has been defined as a "lack of motivation that is not attributable to diminished level of consciousness, cognitive impairment, or emotional distress" [Marin, 1990 and Marin, 1991]. It is manifested clinically by diminishment in goal-directed behaviour, goal-directed cognition, and affective responsivity to events. Signs and symptoms of apathy have long been recognized as common in schizophrenia.
