There are several globally recognized tools used to monitor the severity of Parkinson’s disease as well as track the quality of life. The Unified Parkinson's Disease Rating Scale (UPDRS) is a globally recognized tool used to assess the severity of Parkinson’s disease. The Parkinson’s disease Questionnaire (PDQ-39) is used to measure the health status of people living with Parkinson’s disease specifically focusing on 8 aspects related to quality of life.

Multiple studies have demonstrated a reduction in UPDRS III and PDQ-39 scores, which correlates with an improvement in motor function & quality of life.
