At present, the brain pacemaker has become an important surgical method for the treatment of Parkinson’s disease. More and more post-operative patients often ask questions about the improvement of symptoms and the adjustment of stimulation parameters after surgery, which I have summarized and give a unified answer here. 1.When is it better to turn on the computer after the brain pacemaker surgery? A: Generally, 1-3 weeks after pacemaker surgery is fine. However, for some special patients, a different time can be used. For example, patients with more severe tremor can be turned on earlier to facilitate the recovery of the patient after surgery. Adjustment of stimulation parameters will be performed afterwards. 2.When do the symptoms start to improve after pacemaker surgery and which symptoms improve best? A: After the brain pacemaker surgery is turned on, most of the symptoms of Parkinson’s disease will improve to varying degrees. Tremor, rigidity and slowness improve the best. The improvement of symptoms such as difficulty in starting and turning, difficulty in swallowing, and unclear speech will not be very good. And there is a possibility of aggravation. 3. Do I need to adjust the stimulation parameters frequently after the pacemaker surgery? A: The answer is no. If the stimulation electrodes are placed in an ideal position. If the stimulation parameters are adjusted two or three times within the first year, the chances of further adjustment should be very limited. 4.What do I need to pay attention to in my life after pacemaker surgery? A: Many patients are worried about whether their lives will be affected after surgery. In fact, after brain pacemaker surgery, life in general will not be affected. Just avoid the parts of the pacemaker battery from touching magnetic objects. For example, refrigerator door, microwave oven door, etc. If MRI examination is performed it needs to be turned off. 5. Do the batteries of the pacemaker need to be replaced? A: The answer is yes. If you have a non-rechargeable battery installed, you may need to replace the battery every 5 to 6 years, depending on the amount of electricity used. If you have a rechargeable one, then the battery needs to be replaced every 9 years. 6.Can I do airplane after pacemaker surgery? Can I go through security check? A: After pacemaker surgery, you can travel safely on any transportation, including airplanes. And you can go through the normal security check. If the security officer detects any metal objects in your body, you can simply show him your pacemaker implantation card.
