The first choice is drug therapy, which is a better way to treat Parkinson's disease. The choice of drugs for drug therapy should be based on factors such as patients' age, work nature and disease type, starting with a small dose, gradually increasing and individualized treatment. In addition, the treatment of Parkinson's disease should adhere to long-term medication, and then combined medication, usually in the case of a single drug, the treatment effect is not good, but Parkinson's disease treatment. Secondly, we must distinguish between primary Parkinson's disease and Parkinson's syndrome. The principle of drug treatment for Parkinson's disease should be individualized treatment. Drug therapy is not simple drug therapy, but individualized guidance for different Parkinson's patients and different conditions.
