Parkinson’s disease surgery is now more mature, namely the implantation of a deep brain electrical stimulator, commonly known as brain pacemaker surgery, which is less invasive and safer. Patients are rigorously evaluated before surgery and if they are deemed suitable for surgery, the procedure is more effective with fewer side effects. Some patients may experience side effects such as numbness of the limbs, blurred vision, and voice changes, which will gradually disappear by adjusting the stimulator’s voltage, frequency, pulse width, and other parameters outside the body at a later stage. Clinically, it is believed that Parkinson’s patients are less likely to experience side effects after they have passed the danger period of surgery.
