What are the subtypes of schizophrenia?

ANSWER

At one time, doctors classified schizophrenia based on distinct subtypes, including:

Scientists think the above distinctions are no longer as accurate or useful as once thought and therefore instead just focus on describing symptoms and their severity.

  • Paranoid: Where someone feels he is being persecuted or spied on.
  • Disorganized: Where people appear confused and incoherent.
  • Catatonic: Where people can be physically immobile or unable to speak.
  • Undifferentiated schizophrenia: A subtype in which no paranoid, disorganized or catatonic features are prominent .
  • Residual Schizophrenia: In which psychotic symptoms are markedly diminished or no longer present .
