For psychosis in Parkinson's disease, which medication is commonly used?

  1. Risperidone

  2. Quetiapine

  3. Ziprasidone

  4. Olanzapine

The correct answer is: Quetiapine

In Parkinson's disease, psychosis is a common symptom that can be challenging to manage. Quetiapine is the preferred choice among the options listed for treating psychosis in Parkinson's disease patients. Quetiapine is an atypical antipsychotic that has a lower risk of worsening motor symptoms compared to typical antipsychotics like risperidone, ziprasidone, and olanzapine. It is also considered to have a favorable side effect profile in this patient population. Therefore, quetiapine is often the medication of choice for treating psychosis in Parkinson's disease patients.
