Patients with Parkinson's disease can control the progression of the disease through drug treatment, but it cannot cure the disease.

In the early stage, drug treatment can stimulate and supplement the secretion of dopamine. However, after 3 to 5 years of drug treatment, the effect is not very obvious, and certain side - effects may occur. Patients will then experience Parkinson's symptoms. At this time, surgical treatment can be selected, which can achieve the goal of relieving symptoms.

The functions of drug treatment include stimulating nerve cells to secrete dopamine, reducing the consumption of dopamine in the body, and enhancing the efficiency and activity of dopamine receptors.
