Parkinson’s syndrome is a degenerative disease of the nervous system that manifests as a cluster of Parkinson’s disease-like symptoms. Patients with Parkinson’s syndrome may exhibit limb tremors like those seen in Parkinson’s disease. There are many causes of Parkinson’s syndrome, and the common ones are as follows: 1, drug effects: the use of drugs that block or interfere with dopamine transmission, or drugs that cause impairment of smooth muscle movement mechanisms, causing patients to develop movement disorders in their motor muscles; 2, degenerative diseases: such as Alzheimer’s disease, progressive supranuclear palsy, and degenerative changes in the cortical basal ganglia; 3, viral encephalitis: including West Nile viral encephalitis and rare brain inflammation following influenza-like infections; 4, head injuries: especially recurrent injuries in boxing; 5, various toxic substances: such as manganese, carbon monoxide, methanol and other poisoning, which may damage the brain nerves and cause symptoms such as tremor and myotonia; 6, Wilson’s disease: an autosomal recessive genetic disorder common in adolescents that presents with congenital copper metabolism disorders.
