Unified Parkinson's Disease Rating Scale (UPDRS) ADL + Motor Score
The UPDRS has 3 subscales including Mentation (4 questions based on patient report with answers on a scale of 0-4, with a total of 16 points), Activities of Daily Living (13 questions based on patient report with answers on a scale of 0-4, with a total of 52 points) and Motor (27 questions based on clinician assessment on a scale of 0-4, with a total of 108 points).

Parkinson's Disease Questionnaire - 39 (PDQ-39)
The PDQ-39 is a measure of quality of life in Parkinson's disease patients. It has 39 questions each with a response from 0-4 for a total of 156 points. The total score is calculated as a percentage so the scores of the 39 items are added and divided by 156 and multiplied by 100. The higher the score the worse quality of life.
Time frame: 4 months
Montreal Cognitive Assessment (MoCA)
The MoCA is an assessment of cognitive function. The total possible score ranges from 0 to 30 points with a lower score representing greater cognitive impairment.
