Schizophrenia is often thought of as "split personality". This is a misconception, as the person suffering from schizophrenia does not have more than one distinct personality as is seen in Dissociative Identity Disorder (Multiple Personality Disorder). Instead, they are characterized by having psychosis with, generally, two or more of the following: delusions, hallucinations (visual or auditory), disorganized speech (derailment of speech or incoherence), disorganized or catatonic behavior, or negative symptoms such as flattening of affect or lack of motivation.
