Diagnostics
- An uninterrupted duration of illness during which there is a major mood episode (manic or depressive) in addition to criterion A for schizophrenia; the major depressive episode must include depressed mood.
- Hallucinations and delusions for two or more weeks in the absence of a major mood episode (manic or depressive) during the entire lifetime duration of the illness.
- Symptoms that meet the criteria for a major mood episode are present for most of the total duration of both the active and residual portions of the illness.
- The disturbance is not the result of the effects of a substance (e.g., a drug of misuse or a medication) or another underlying medical condition.
- ≥ 2 weeks of psychosis without prominent manic/depressive symptoms during the illness episode, to differentiate from a mood disorder with psychotic features (Like MDD)
- MDD doesn’t have psychotic symptoms alone without mood symptoms
- A single illness episode where both of the following occur concurrently:
- Psychotic symptoms that meet the criteria for schizophrenia
- Features of a major mood episode (major depressive episode OR manic episode OR mixed episode)
- Psychotic symptoms occur at least once in the absence of mood disorder symptoms.
