Question

A 78-year-old man with Parkinson disease experiences worsening of his symptoms. He is already taking levodopa. Since the disease is characterized by degeneration of dopaminergic neurons, leading to the lack of inhibition of cholinergic neurons, the addition of which medication is likely to help alleviate the patient's symptoms?

(A) Benztropine
(B) Reserpine
(C) Doxazocin
(D) Timolol
(E) Tubocurarine

Answer 1

The addition of Benztropine is likely to alleviate the patient's symptoms of Parkinson's disease.
