Deep brain stimulation includes implanting electrodes within certain areas of your brain. These electrodes produce electrical impulses that regulate abnormal impulses. Or the electrical impulses can affect some cells and chemicals within the brain. The amount of stimulation in deep brain stimulation is managed by a pacemaker-like device placed under the skin in your upper chest. A wire that travels under your skin attaches this device to the electrodes in your brain.
Deep brain stimulation is an established procedure for people with movement disorders, such as essential tremor, Parkinson’s disease and dystonia, and psychiatric conditions, such as obsessive-compulsive disorder. It’s also approved for use by the Food and Drug Administration to decrease seizures in difficult-to-treat epilepsy. This treatment is reserved for people who aren’t ready to get control of their symptoms with medications.
Deep Brain Stimulation (DBS)- Procedure
Before surgery, you’ll need medical tests to make sure that deep brain stimulation is a safe and appropriate option for you. You’ll also require brain-imaging studies, such as an MRI, before the surgery, to map the areas of your brain to implant the electrodes.
