Epidemiology of Parkinson's disease

Parkinson's disease (PD) is a common neurodegenerative disease in the aged populations, which is characterized by resting tremor, rigidity, bradykinesia and abnormal gait, accompanied by a variety of non-motor symptoms (NMS). The prevalence and incidence of PD rise sharply with the increase of age. In the advent of global aging, the rapid growing of elderly populations results in a rising number of PD patients, especially in China. A correct understanding of the epidemiology of PD helps to respond to this challenge actively. This article aims to provide an overview of the prevalence, incidence and mortality of PD and their differences among regions. Special efforts are made to illustrate the current status and future trends of the epidemiology and economic burden of PD in China. DOI: 10.3969/j.issn.1672-6731.2016.02.007
