Schizoaffective Disorder Symptoms

Schizoaffective disorder is characterized by the presence of a generally continuous psychotic illness plus intermittent mood episodes. Mood episodes are present for the majority of the total duration of the illness, which can include either one or both of the following:

The psychotic illness criteria resembles Criterion A of the schizophrenia diagnosis, requiring at least two of the following symptoms for at least one month:

  • Delusions
  • Hallucinations
  • Disorganized speech (e.g., frequent derailment or incoherence)
  • Grossly disorganized or catatonic behavior
  • Negative symptoms (e.g., affective flattening, alogia, avolition)

(Only one symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the person’s behavior or thoughts, or two or more voices conversing with each other.)

The occurrence of the delusions or hallucinations must be in the absence of any serious mood symptoms for at least 2 weeks. The mood disorder, however, must be present for a significant minority of the time.

In order for this condition to be diagnosed, the symptoms experienced by a person must not be better explained by the use or abuse of a substance (alcohol, drugs, medications) or a general medical condition (such as a stroke). If the mood symptoms are present for only a relatively brief period, the diagnosis of schizophrenia is usually made, not schizoaffective disorder. Only a qualified mental health professional can make a diagnosis for this condition.

In schizoaffective disorder, occupational functioning is frequently impaired, but this is not a defining criterion (in contrast to schizophrenia).

Restricted social contact and difficulties with self-care are associated with schizoaffective disorder, but negative symptoms may be less severe and less persistent than those seen in schizophrenia.

Schizoaffective disorder is less common than schizophrenia.
