Zapping the brain to ease Parkinson's hidden struggles

This small study explored whether gentle electrical stimulation to the brain's surface could help control the depression, anxiety, and impulsive behaviors that often accompany Parkinson's disease. Five patients who were already having surgery for a standard deep brain stimulator also had a flexible electrode placed over the front part of their brain. Researchers recorded brain signals and tested stimulation over two years to see if it could reduce these difficult non-motor symptoms and improve patients' quality of life.
