D29 – 2.2 Schizophrenia


Two or more of the following present for a significant portion of the time during a 1 month period. And at least 1 of this must be (1), (2) or (3):

  1. Delusions.
  2. Hallucinations.
  3. Disorganized speech.
  4. Grossly disorganized behavior or catatonia.
  5. Negative symptoms.

This differs from Treatment Resistant Depression because in that condition psychotic symptoms such as hallucinations, delusions and disorganized speech are not the prominent symptomatology criteria.
