ABSTRACT
Schizophrenia is one of the most disabling of all mental illnesses. It is characterized by disordered thinking, perceptual disturbances such as hallucinations, and delusional beliefs (positive symptoms), as well as deficits in motivation, socializa tion, and affect (negative symptoms). The illness begins in adolescence or early adulthood and leads to a marked decline in occupational and interpersonal function.
