How can you differentiate schizophrenia from mood disorder with psychotic features in terms of psychotic symptom duration?

• A. In schizophrenia, psychotic symptoms persist across illness and can occur without mood symptoms; in mood disorders with psychotic features, psychotic symptoms occur only during mood episodes.
• B. In mood disorders psychotic symptoms persist across illness
• C. In schizophrenia psychotic symptoms only during mood episodes
• D. Duration cannot differentiate

Answer: (A)

What’s being tested is how the timing of psychosis relates to mood symptoms over the course of illness. In schizophrenia, psychotic symptoms can be present for long periods and may occur even when mood is not disturbed, meaning the psychosis persists across different times and states. In mood disorders with psychotic features, the psychotic symptoms appear only during mood episodes (depression or mania) and tend to disappear when the mood returns to baseline. So, the duration pattern is the clue: persistent, mood-independent psychosis suggests schizophrenia, while psychosis limited to mood episodes points to a mood disorder with psychotic features. If psychosis occurs both with and without mood symptoms, that would suggest another diagnosis, like schizoaffective disorder.
