Schizoaffective Disorder

Schizoaffective disorder can be difficult to diagnose because it has symptoms of both schizophrenia and either depression or bipolar disorder. There are two major types of schizoaffective disorder: depressive type and bipolar type. To be diagnosed with schizoaffective disorder a person must have the following symptoms:

  • A period during which there is a major mood disorder, either depression or mania, that occurs at the same time that symptoms of schizophrenia are present.
  • Delusions or hallucinations for 2 or more weeks in the absence of a major mood episode.

Symptoms that meet criteria for a major mood episode that are present for the majority of the total duration of the illness.

This diagnostic framework involves elements of both conditions, schizophrenia and mood disorders. As with schizophrenia and mood disorders such as bipolar disorder or major depressive disorder, these are symptom-based diagnoses. There are no biomarkers (like blood pressure or sugar levels) to confirm a diagnosis at this time. NAMI has partnered with the Foundation of the National Institute of Health and many other public and private entities to create the Accelerated Medicines Partnership for Schizophrenia (AMP-SCZ). This international coordinated research effort seeks to biologically identify people who are at risk of developing psychosis to help create biomarkers to improve diagnosis and early intervention.

For an accurate diagnosis, the symptoms cannot be attributed to substance use or another medical condition.

Cultural Considerations

Research shows that Black and Latino individuals are more likely to be misdiagnosed with schizoaffective or other psychotic . Factors such as provider bias and limited access to culturally responsive care can all contribute to this disparity. Working with a mental health professional who understands your cultural background and values can help ensure an accurate diagnosis and effective treatment.
