This time, Mr. Li came to Beijing General Hospital because he felt some stiffness in one of his limbs again after a period of time and had frequent tremors. After a brief consultation and examination at the outpatient clinic, the chief surgeon, Dr. Jianghong He, performed a neuromodulation parameter adjustment for him, and Mr. Li’s tremor disappeared completely and he was able to walk freely again. However, he also complained that the effect was unstable and caused him a lot of trouble. This was his third visit to the clinic to adjust the parameters. Mr. Li lives in Fuzhou City and each time he makes a special trip to Beijing, it is quite difficult and costly to travel. This time, the voltage of the stimulation was only slightly increased. The last adjustment had set a certain range for the patient controller, and the stimulation effect can be increased appropriately when it decreases. Mr. Lee said, I dare not myself, although I am also a doctor, but this kind of brain inside with a little something, I dare not. This is a problem often encountered after Parkinson’s DBS. In fact, the benefit of DBS is that it is safe, controllable and adjustable. The machine itself has an adjustment function and the patient himself can make adjustments according to his symptoms. However, because they are not familiar with the performance of the machine at the beginning, patients are always particularly worried that messing with the adjustments will lead to danger. This is a misconception, because usually the adjustment range authorized by the doctor to the patient is within a certain safety range, and as long as the doctor’s instructions are followed, none of them will bring danger. This is a small issue, but a technique that can greatly reduce the number of outpatient follow-up visits, especially for patients who live far away. Parkinson’s disease is a common neurodegenerative disease that is treated with medications in the early stages, but generally after a 5-6 year drug “honeymoon” period, symptoms can increase significantly and worsen, and continued increases in medications can lead to a series of serious side effects. In the later stages of Parkinson’s disease, surgery becomes the only means to relieve symptoms, reduce drug doses, and eliminate drug side effects. The most common procedure used today is the implantation of a brain pacemaker (DBS). The vast majority of postoperative results are very good and it is currently the standard of care in the treatment of Parkinson’s disease. However, this procedure requires high technical requirements for surgical equipment and surgeons, so it is mostly performed in some larger hospitals.
