Parkinson’s disease is a common neurological disorder that occurs in middle-aged and elderly people, mainly due to the loss of dopaminergic neurons in the substantia nigra of the brain. The main symptoms are slow movement, tremor, muscle stiffness and postural balance disorders. Other symptoms include smaller and smaller writing, dull expressions, and a monotonous, low-pitched voice. Although Parkinson’s disease does not directly lead to the death of the patient, it will seriously affect the patient’s daily life and reduce the quality of life. Parkinson’s disease medication, such as Dobasic Hydrazide (Medoxomil), Carbidopa (Xining) has a good effect on controlling the patient’s symptoms, the drug treatment has a “honeymoon period” of about 3 to 5 years, but with the progress of the disease, the efficacy of the drug will gradually decline, each time the medication to maintain the time is getting shorter and shorter, the symptoms of the ups and downs fluctuation, good and bad, as well as drug-induced fluctuations, the symptoms of the patient’s life. However, as the disease progresses, the efficacy of the medication gradually decreases, the duration of the medication becomes shorter and shorter, the symptoms fluctuate, come and go, as well as drug-induced “choreographic” movements (which we refer to as “anisocoria”) or severe gastrointestinal reactions, etc., at this stage, it is necessary to consider surgical treatment. Surgery can be categorized into disfiguring surgery and deep brain stimulation (DBS, also known as pacemaker surgery), which has fewer adverse effects, is safer, and is reversible and modifiable. The surgical procedure for DBS involves implanting stimulating electrodes into the nuclei of the brain (thalamic floor nuclei), which are connected via subcutaneous wires to a stimulation generator (battery) implanted under the skin in the chest. The entire device is buried under the skin, and the incision heals without interfering with activities such as moving around and bathing. After the surgery, the doctor can adjust the stimulation parameters according to the severity of the disease. the DBS procedure has good long-term results, and most patients can moderately reduce the amount of medication and improve the adverse effects of medication. Therefore, DBS is especially suitable for patients who suffer from side effects of drugs, poor therapeutic effects, uncontrollable fluctuation of symptoms and “anisotropy”.
