Parkinson's disease is a degenerative disease of the nervous system. The actual mechanism of the disease is not very clear, and its fundamental cause has not yet been identified. It is generally believed that Parkinson's disease is mainly caused by the following factors. First, genetic factors. Some cases of Parkinson's disease have a clear familial tendency, where patients may experience mutations in synaptic nuclear protein genes, leading to abnormal aggregation of these proteins. This abnormal aggregation can damage the neurons in the substantia nigra of the midbrain, leading to Parkinson's disease. Second, there are some external factors related to sporadic cases of Parkinson's. These may be closely related to oxidative stress, trauma, poisoning, or an excessive stress response of the body. However, the specific cause is not very clear. Parkinson's disease, which causes symptoms such as bradykinesia, tremors, and rigidity, requires active treatment to improve the quality of life of the patients.
