Disorganized schizophrenia

Disorganized schizophrenia, also known as hebephrenia, is a subtype of schizophrenia, although it is not recognized in the latest version of the DSM.

Disorganized schizophrenia is thought to be an extreme expression of the disorganization syndrome that has been hypothesized to be one aspect of a three-factor model of symptoms in schizophrenia, the other factors being reality distortion (involving delusions and hallucinations) and psychomotor poverty (lack of speech, lack of spontaneous movement and various aspects of blunting of emotion).
