Antiparkinson agents are medications that help to control the symptoms of Parkinson's disease. Parkinson's disease is a neurologic disorder which is progressive and eventually debilitating. Patients with Parkinson's experience tremors, difficulty walking, and cognitive problems. Antiparkinson agents allow the patient to live a relatively normal life, but unfortunately many of them have rather severe side effects.
