Deep brain electrical stimulation therapy involves the implantation of electrodes in specific nerve clusters in the brain, and the continuous release of high-frequency electrical stimulation by a pulse generator inhibits the electrical impulses of these neurons that are overexcited due to a decrease in dopaminergic neurons, thus achieving the purpose of treatment. The brain pacemaker is a sophisticated set of microelectronic devices consisting of a pulse generator, electrodes and extension leads, all of which are implanted in the body and do not interfere with daily life. Questions and answers about brain pacemakers: 1. What are the advantages of brain pacemakers for Parkinson’s disease? Safe and effective: more than 100,000 people worldwide have been treated with deep brain electrical stimulation therapy; Minimally invasive: fast recovery after surgery; Reversible: no permanent neurological or neurophysiological damage; Adjustable: according to the patient’s specific condition, the stimulation parameters can be adjusted; Can improve bilateral limb symptoms at the same time; Extend the patient’s open period time; Can enable Parkinson’s disease patients to significantly reduce the need for anti-Parkinson’s disease drugs; Deep brain electrical stimulation therapy can enable deep brain electrical stimulation treatment can make Parkinson’s disease patients significantly improve motor function and improve quality of life. 2.Surgical procedure? 3. What is the size and weight of the battery implanted in the brain pacemaker? In the design of the pacemaker battery, the human body characteristics are fully considered, and the implantable battery is designed to be compact and smooth in appearance on the basis of the battery’s electrical capacity to reduce the discomfort caused by the implantation of foreign bodies. The weight of the battery varies from 35 to 55 grams depending on the product model, and the thickness is about 1 cm. 4.Does the pacemaker have a power-saving mode and how can it be used to save power? It can be programmed by the doctor according to the patient’s own situation to set the cycle mode to meet the patient’s treatment needs to the greatest extent. 5. How long does it take to turn on the pacemaker after surgery? Why do I need regular follow-up after surgery? About how often? There is no principle requirement for the specific time to turn on the pacemaker after installation. The reason for not turning on the pacemaker immediately after surgery is that the electrode implantation will produce a micro-destructive effect after surgery, which is similar to the effect produced by turning on the pacemaker, but the micro-destructive effect usually disappears within a few weeks, so it is more appropriate to turn on the pacemaker in January after surgery to fully respond to the stimulation effect. The start-up time can also be flexible according to the actual needs of the patient. Patients can achieve the ideal effect of preoperative evaluation after a few times of postoperative programmed debugging, and the appointment time of programmed debugging can be mastered according to individual patient’s treatment situation and time.
