Parkinson's Disease

Rating Scales

The standard tool for tracking Parkinson's disease progress and response to therapy is the United Parkinson's Disease Rating Scale (UPDRS). The UPDRS is subdivided into three scales including cognitive and mood aspects, motor aspects, and activities of daily living (ADL). A lower score indicates a better condition than a higher score. The UPDRS is available at http://www.mdvu.org/library/ratingscales/pd/.
