Types of Schizophrenia

Definition: A mental disorder in which the ability to function is impaired by severely distorted beliefs, perceptions, and thought processes.

Disorganized: Incoherent speech and inappropriate, often silly, emotion. The individual may be extremely withdrawn and behavior may include odd grimaces and mannerisms.

Catatonic: Bizarre physical movements, ranging from motionless stupor to violent hyperactivity and sometimes alternating between these two extremes.

Paranoid: Delusion of persecution or grandeur. The individual may trust no one and may be anxious or angry about supposed tormentors.

Undifferentiated: Delusions, hallucinations, and incoherence typical of schizophrenia; however, the individual does not neatly fit any of the other types.

Residual: Minor symptoms of schizophrenia lingering after a serious episode.
