Deep brain stimulation is a surgical procedure in which a thin wire is implanted deep within the brain to deliver an electrical current. The current helps to block abnormal brain activity that causes the tremors and other symptoms that are the hallmark of Parkinsons Disease. While it is not a cure, it is effective in improving quality of life for people with this disease. Other than the dangers of the surgical procedure itself, it seems to carry fewer side effects than the medications that have traditionally been used for Parkinson’s. A new study being reported in the New England Journal of Medicine confirms these findings. Deep brain stimulation has generally only been available to those with the most severe symptoms of advanced Parkinson’s.
