Parkinson’s is a progressive disease that begins with a distal tremor or strong value in one limb and slowly progresses to the other limb. Its main manifestations are resting tremor, muscle tonus, reduced or slowed movements, and postural balance and gait disturbances. Usually, after 3-5 years from the time of diagnosis, patients will be on 2-3 heavy medications and experience varying degrees of reduced efficacy or side effects of the medication. The patient’s quality of life is also greatly affected when there are anomalies, end-of-season phenomena, switching phenomena, etc. At this time, doctors often recommend that patients be evaluated for surgery and receive surgical treatment at the appropriate time. Due to economic conditions, patients with Parkinson’s disease in China are evaluated for surgery at least 2-3 years later than foreign patients. The preoperative evaluation mainly assesses two points: 1. whether the patient is suitable for surgery; 2. whether the patient can tolerate surgery; for the suitability of surgery, it is necessary to do: cranial MRI, Medobar shock test, disease progression assessment (previous disease, medical history analysis; the rate of development of Parkinson’s disease and changes in symptoms of the disease are also important assessment factors); mental psychological scale assessment; for the assessment of whether the patient can tolerate surgery, it is necessary to do electrocardiogram, liver and kidney function To ensure that the patient can tolerate the surgery, electrocardiogram, liver and kidney function tests are required.
