Which drug is known for causing somnolence and metabolic syndrome but is often used for psychosis in Parkinson's disease due to lower EPS risk?

  1. Risperidone

  2. Quetiapine

  3. Olanzapine

  4. Paliperidone

The correct answer is: Quetiapine

Quetiapine is the correct answer because it is known for causing somnolence and metabolic syndrome. Despite these side effects, it is often preferred for psychosis in Parkinson's disease due to its lower risk of causing extrapyramidal symptoms (EPS) compared to other antipsychotic medications. Risperidone (Option A), Olanzapine (Option C), and Paliperidone (Option D) are all atypical antipsychotic medications which are commonly used in the treatment of psychosis. However, they have a higher risk of causing EPS compared to Quetiapine, making them less preferred in patients with Parkinson's disease.
