Sub-Types

Some researchers believe schizophrenia is a single disorder, but others believe it is a syndrome based on numerous underlying disorders. Subtypes of schizophrenia have been proposed in an effort to classify people into more distinct groups but just because you are in one subtype that does not mean you stay in that subtype. Subtypes include the following:


 * **Paranoid:** People are preoccupied with delusions or auditory hallucinations. Disorganized speech and inappropriate emotions are less prominent.
 * **Disorganized:** Speech and behavior are disorganized, and people do not express emotions or have inappropriate emotions.
 * **Catatonic:** Symptoms are mainly physical. They include immobility, excessive motor activity, and assumption of bizarre postures.
 * **Undifferentiated:** People have a mixture of symptoms from the other subtypes: delusions and hallucinations, thought disorder and bizarre behavior, and negative symptoms.
 * **Residual:** People have had a clear history of prominent schizophrenia symptoms that are followed by a long period of mild negative symptoms.
