Schizoaffective Disorder
Symptoms

This disorder is characterized by the presence of one of the following:

• Major Depressive Episode (must include depressed mood)
• Manic Episode
• Mixed Episode

(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).
