Parkinson's Disease Questionnaire-39 (PDQ-39) is the most widely used measurement tool in assessing the quality of life of PD patients. In PD, a series of features can affect the quality of life including the degree of disease severity and the number of medications. The aim of this study is to determine the relationship between the severity of the disease and the number of medications with the quality of life of people with PD so that it is hoped that it can help improve the quality of life of PD patients.

Stage 2 on Hoehn and Yahr Scales is the most common severity level of disease (55.3%), and polytherapy is the majority of the number of medications (74.5%). The median value of quality of life is 35, with the lowest score being 10 and the highest score being 98. From the results of the bivariate analysis, it was found that there was a very strong, significant association between the degree of disease severity and the quality of life (p |
