Study Summary

This study is designed to determine whether dextromethorphan, a drug commonly found in cough medicine, is beneficial and safe for the treatment of Parkinson's disease and other diseases that might share biochemical abnormalities with Parkinson's disease. Patients with Parkinson's disease are missing the chemical neurotransmitter dopamine. This occurs as a result of destructive changes in an area of the brain responsible for making dopamine, the basal ganglia. Rhythmical muscular tremors, rigidity of movement, shuffling footsteps, droopy posture, and a mask-like expression on the face characterize Parkinson's disease. Researchers believe that dextromethorphan may be able to safely modify psychomotor function of patients with Parkinson's Disease.
