A 65-year-old man presents to a neurologist complaining of a resting tremor. He is accompanied by his wife, who points out that her husband has been moving much more slowly, he has not been sleeping well, and has been depressed and anxious. During the interview, the patient speaks in a low tone without facial expression, and his left hand has a resting tremor involving the fingers and wrist. Physical examination reveals a wide, shuffling gait without arm swing. Passive movement of the arms demonstrates uniform resistance to movement with a ratchet-like quality.
