from Psych central websight:

SYMPTOMS
Schizoaffective Disorder is characterized by the presence of one of the following:

Major Depressive Episode (must include depressed mood)
Manic Episode
Mixed Episode
As well as the presence of 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. The symptoms of this disorder also can not be better explained by the use or abuse of a substance (alcohol, drugs, medications) or a general medical condition (stroke).
