Question: 225
1. What is one "positive" symptom of schizophrenia?
- A. Catatonia
- B. Weight gain
- C. Flattened affect
- D. Auditory or visual hallucinations
Correct Answer: D
Explanation:
A "positive" symptom of schizophrenia is an addition to, excess of, or distortion of normal functions; auditory or visual hallucinations are positive symptoms of the illness (choice D is correct). A "negative" symptom of schizophrenia is a diminishment or absence of normal function; catatonia (lack or responsiveness to stimuli) and flattened affect (lack of emotion) are both negative symptoms (choice A and choice C are wrong). Weight gain is often a side effect of psychotropic medications, not a symptom of schizophrenia (choice B is wrong).
