Schizoaffective disorder is a mental disorder in which a person experiences a combination of schizophrenia symptoms, such as hallucinations or delusions, and mood disorder symptoms, such as depression or mania. The two types of schizoaffective disorder — both of which include some symptoms of schizophrenia — are:

  • Bipolar type, which includes episodes of mania and sometimes major depression
  • Depressive type, which includes only major depressive episodes

Schizoaffective disorder may run a unique course in each affected person, so it's not as well-understood or well-defined as other mental health conditions.

Untreated schizoaffective disorder may lead to problems functioning at work, at school and in social situations, causing loneliness and trouble holding down a job or attending school. People with schizoaffective disorder may need assistance and support with daily functioning. Treatment can help manage symptoms and improve quality of life.
