Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Levodopa is the main drug treatment for Parkinson's disease. Levodopa can cause unwanted and uncontrolled movements called dyskinesias. A drug called amantadine can reduce these movements. To date, there are no objective measures of these movements. The purpose of this study is to measure the reduction of the movements by amantadine and/or topiramate using an objective measure.
