Parkinson’s disease, also known as tremor palsy, was first introduced by British physician James Parkinson 200 years ago as a common movement disorder in middle-aged and elderly people. The medical definition of Parkinson’s disease is a chronic progressive disease that gradually worsens over time, not fatal but affecting the patient’s ability to work and quality of life; it is mainly manifested by abnormalities in movement and is a movement disorder; clinical symptoms can be improved or alleviated through treatment. There are more than four million people with Parkinson’s disease worldwide, and there are more than two million people with PD in China. The prevalence of PD increases with age, generally above 1% in people over 55 years of age, and increases to 1.7% in people over 65 years of age. With the advent of an aging global population, there is an increasing trend of Parkinson’s disease patients. Parkinson’s disease is the most common neurodegenerative disease other than Alzheimer’s disease.
