What is Parkinson's disease?

Parkinson's disease is a degenerative disease of the central nervous system. It was first reported by a British doctor named James Parkinson, so it was named Parkinson's disease after him. Parkinson's disease is a group of clinical symptoms caused by the decrease of dopamine after the decrease of substantia nigra cells in the brain. It is a systemic disease, so there are many symptoms, including motor symptoms and non-motor symptoms. Motor symptoms are unique symptoms of Parkinson's disease. Although non-motor symptoms are not unique to Parkinson's disease, they often exist in patients before the symptoms of Parkinson's disease appear, and along with the whole course of Parkinson's disease, they will also affect the quality of life of patients.

The typical manifestations of exercise symptoms are slow movements, that is, slow movements, slow movements such as walking, dressing and doing housework, and easy to stoop. When you walk, you can't take a step, your steps are very small, your legs are particularly heavy, and your feet are like sticking to the ground, so you get tired easily. When you are quiet, your hands or legs will shake, which is clinically called static tremor. Some patients have no obvious tremor, but the stiffness is more obvious. There are many non-motor symptoms, such as very common sense of smell loss, constipation, sleep disorders, and emotional disorders, such as anxiety and depression. Others include dizziness, numbness of limbs, backache and backache. Parkinson's disease can't be cured at present, and its symptoms will get worse with age, so it can only be maintained by taking medicine for life.
