The old criteria in the DSM-IV divided schizophrenia by different Types. Though we not longer use such specifiers in the updated DSM-5, they remain below for informational/historical purposes.

A brief list of types of schizophrenia, according to DSM-IV:

  • Paranoid schizophrenia— a person feels extremely suspicious, persecuted, grandiose, or experiences a combination of these emotions.
  • Disorganized schizophrenia  — a person is often incoherent but may not have delusions.
  • Catatonic schizophrenia— a person is withdrawn, mute, negative and often assumes very unusual postures.
  • Residual schizophrenia — a person is no longer delusion or hallucinating, but has no motivation or interest in life. These symptoms can be most devastating.
