Schizophrenia is a stress-related, neurobiological disorder characterized by disturbances
in the form and content of an individual's thought and perceptual processes, affect and
social and instrumental role behavior.
The pervasive impact of schizophrenia across
perceptual, cognitive, emotional and behavioral domains, as well as the heterogeneity
within those domains require a multimodal and comprehensive approach to treatment and
rehabilitation which involves the individual and his or her environment.
