To succeed in AP Psychology, you must first grasp the fundamental definition provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Schizophrenia is categorized under psychotic disorders, which are conditions where a person loses some contact with reality.

One person might have severe hallucinations but mild cognitive issues, while another might have profound negative symptoms but fewer positive ones.
