DEFICIT STATES OF SCHIZOPHRENIA
The concept of "deficit schizophrenia" was introduced to distinguish a relatively homogeneous subgroup of individuals within schizophrenia. Deficit schizophrenia is characterized by persistent primary negative symptoms such as restricted affect, diminished emotional range, poverty of speech, curbing of interests, and reduced sense of purpose and social drive. Kirkpatrick and colleagues (2001) found that deficit schizophrenia exists among 15% of firstepisode individuals and among 25%–30% of those with chronic schizophrenia. The clinical features of schizophrenic deficit states refer to the cohesive and idiopathic set of signs and symptoms as presented in the Schedule for Deficit Syndromes (Kirkpatrick et al. 1989).
