Clinical rating scales

SummaryIn Parkinson's disease (PD), rating scales are used to assess the degree of disease-related disability and to titrate long-term treatment to each phase of the disease. Recognition of non-motor symptoms required modification of existing widely used scales to integrate non-motor elements. In addition, new scales have been developed for the assessment of non-motor symptoms. In this article, assessment of PD patients will be discussed, particularly for non-motor symptoms such as pain and fatigue.
