Schizophrenic Disorders

Schizophrenia (SZ) literally means "split" ("schizo-") + "mind" ("phrenia). However, the split was originally thought to be between the thinking and the feelings of the person. It DOES NOT mean that there are several people inside one person. That is a condition called "Dissociative Identity Disorder" (formerly, Multiple Personality Disorder).

= A class of disorders marked by delusions, hallucincations, disorganized speech, and deterioration in adaptive behaviors
