Which disorder features concurrent mood episodes with psychotic symptoms and is treated the same as schizophrenia?

• A. Schizophrenia
• B. Schizophrenia with mood disorder
• C. Schizoaffective disorder
• D. Delusional disorder

Answer: (C)

Schizoaffective disorder is defined by the presence of psychotic symptoms that meet schizophrenia criteria plus concurrent mood disturbances (depression or mania), with mood symptoms occupying a substantial portion of the illness, and a period of psychosis without prominent mood symptoms at some point in the course. This combination distinguishes it from pure schizophrenia (psychosis without significant mood episodes) and from mood disorders with psychotic features (psychosis occurs only during mood episodes). Treatment centers on antipsychotic medications, similar to schizophrenia. Because mood symptoms are also present, clinicians may add mood stabilizers or antidepressants as needed, but the core approach targets psychosis, which is why it’s treated the same as schizophrenia in many respects. Delusional disorder lacks prominent mood symptoms; a mood disorder with psychotic features involves psychosis only during mood episodes, not a sustained pattern of psychosis outside mood states.
