Schizoaffective disorder is a condition in which a person experiences a combination of schizophrenia symptoms — such as hallucinations or delusions — and of mood disorder symptoms, such as mania or depression.
Not all experts agree that schizoaffective disorder should be treated as a distinct disorder. Some regard the condition simply as schizophrenia with some mood symptoms, while others view schizoaffective disorder as a separate disease with its own symptoms and treatments.
Untreated, people with schizoaffective disorder may lead lonely lives and have trouble holding down a job or attending school. Or, they may rely heavily on family or psychiatric group homes.
With treatment, people with schizoaffective disorder have a better prognosis than do people with schizophrenia, but not as good as people with mood disorders alone.
