Which disorder has symptoms of both schizophrenia and affective mood disorder?

Schizoaffective Disorder is characterized by the presence of symptoms that are consistent with both schizophrenia and a mood disorder, such as depression or bipolar disorder. This means that in addition to exhibiting psychotic symptoms like delusions or hallucinations typical of schizophrenia, individuals with schizoaffective disorder also experience significant mood disturbances. These mood episodes can occur concurrently with the psychotic symptoms or may arise independently.

The diagnosis is crucial because it directly impacts treatment decisions and prognosis. For instance, the presence of mood symptoms may suggest the need for mood stabilizers or antidepressants in addition to antipsychotic medications. Understanding this overlap helps clinicians tailor their approach to effectively manage both the psychotic and mood symptoms, which is unique to schizoaffective disorder compared to other conditions.

The other disorders listed do not encompass the combination of both schizophrenia and affective mood disorder symptoms. Brief Psychotic Disorder involves sudden onset of psychotic symptoms but does not include mood disorder components. Schizophrenia primarily focuses on long-term psychotic symptoms without an essential mood element. Obsessive-Compulsive Disorder is primarily characterized by intrusive thoughts and compulsive behaviors, lacking the features of psychosis or mood instability.
