Parkinson's disease, also known as paresis shaking, is a movement disease caused by extrapyramidal lesions. It is mainly due to the degeneration of dopamine neurons in the substantia nigra, resulting in insufficient dopamine content in the extrapyramidal system, or an excessive amount of a protein called "PAEL" in the human body, which makes the cholinergic nerve function in this system relatively dominant, causing pathological conditions. Its main characteristics are progressive bradykinesia, muscle rigidity, and tremor. Anti-parkinson's disease APIs are divided into dopamine mimetics and centrally acting anticholinergics.
