Deep-brain Stimulation

Definition: Deep-brain stimulation is a technique that involves precise stimulation of particular parts of the brain through the implantation of removable electrodes. The way in which deep-brain stimulation works is still unknown, but it has been suggested that it restores normal activity to areas of the brain that have become dysregulated. Deep-brain stimulation has shown considerable promise in the treatment of movement disorders such as Parkinson’s disease, and there is a growing evidence that it may be helpful for the treatment of OCD that has not responded to other forms of therapy.
