A new study published in The Journal of the American Medical Association shows that deep brain stimulation may show better improvements in disability and quality of life, as compared to other state-of-the-art treatments for patients with advanced Parkinson’s disease. However, there were also more serious side effects in patients who got deep brain stimulation. Deep brain stimulation requires the surgical implantation of electrodes and a device in the brain in order to electrically stimulate certain brain regions.
