Parkinson’s disease is a degenerative disease of the nervous system that commonly occurs in middle-aged and elderly people, mostly after the age of 60. It is characterized by slow movements, tremors in the arms and legs or other parts of the body, and a loss of flexibility and stiffness. The earliest systematic description of the disease was made by the British physician Dr. James Parkinson, who did not know which category the disease should be classified as and called the disease “tremor palsy”. This name was also used in our old textbooks and is still used by some non-specialists today. Later, more careful observation of the disease revealed that in addition to tremor, there were other symptoms such as muscle stiffness and smaller and smaller writing, but the strength of the muscles of the limbs was not impaired, so it was suggested that the disease be named “Parkinson’s disease.
