Schizophrenia: An Information Guide
Over the years, different types of schizophrenia have been described in a number of ways. The following classifications have
been taken from the Diagnostic and Statistical Manual of Mental Disorders (fourth edition) – DSM-IV.
- Disorganized type – Obvious personality disorganization marked by incoherence and a flat, silly affect. Other common features are making faces,
odd mannerisms, preoccupation with bodily complaints and wanting to be left alone.
- Catatonic type – Marked disturbance in physical activity, either a long period of immobility in a strange position or uncontrollable excitement.
- Paranoid type – Belief that others are plotting against them and persecuting them. May exhibit unreasonable jealousy or think they are
unusually powerful and important. Auditory hallucinations (hearing voices) may accompany these ideas.
- Undifferentiated type – Psychotic symptoms that cannot be found in the above categories. Symptoms from more than one category.
- Residual type – Symptoms of schizophrenia which remain after an active episode.
