Brain pacemaker, also known as deep brain electrical stimulation (DBS), this treatment implants electrodes in specific nuclei in the brain to release high-frequency electrical stimulation, which inhibits the electrical impulses of these neurons that are overexcited due to the reduction of dopaminergic neurons and decreases their overexcited state, thus alleviating the symptoms of Parkinson’s disease. The treatment alleviates the three main symptoms of Parkinson’s disease: tremor, rigidity and motor retardation, especially for The treatment alleviates the three main symptoms of Parkinson’s disease: tremor, rigidity and bradykinesia, and especially improves the midline symptoms, such as difficulty starting and turning over. What can be achieved with pacemaker surgery? The brain pacemaker can control the symptoms of dyskinesia, such as tremor, rigidity, and bradykinesia in Parkinson’s disease patients; at the same time, it can also reduce the duration and severity of the symptoms of dyskinesia caused by long-term use of levodopa drugs, and reduce the fluctuation of symptoms. Professor Wang Xuelian explained that brain pacemaker therapy can control the symptoms of movement disorder continuously and effectively, and improve the patient’s daily living ability and quality of life through long-term electrical stimulation of the brain’s motor nuclei. What tests are required before surgery? Routine physical tests, such as blood tests, cardiac ultrasound, EEG, etc., will be performed 2-3 days before the deep brain electrical stimulation procedure, and the improvement rate of the preoperative Medobar shock test will be measured. Will the deep brain stimulation procedure be visible in appearance? The entire deep brain electrical stimulation system: electrodes, extension leads, and neurostimulator (batteries) are embedded in the body. A small bump, about the size of a matchbox, can be felt on the surface of the skin of the chest, but is not easily visible with clothing on. There may be a small bump on the head, which will be covered by hair for a while after the surgery and is not easily noticed. After the surgery, there is no effect on bathing or even swimming. Is the battery usage of deep brain electrical stimulation permanent? What happens when the battery runs out? The battery life of a neurostimulator varies from person to person, depending on the parameters set and the number and time of day the neurostimulator is turned on, the battery usually lasts 5-8 years. There are currently rechargeable types of pacemakers that can last for more than 10 years. Battery depletion requires battery replacement. Battery replacement is a minor procedure compared to general surgery.
