About 100,000 people worldwide undergo deep brain stimulation to treat Parkinson’s disease, dystonia and tremor when traditional medications or treatments fail to provide symptom improvement or relief. It is also being explored as a treatment for other neurological and psychiatric disorders for which medical therapy has not been effective in alleviating symptoms.
Deep brain stimulation (DBS) involves stimulating portions of the brain through a small implanted device. After the device is implanted, a clinician programs the device to target each patient’s individual symptoms. They establish settings that determine how much stimulation is needed to improve symptoms, a process called programming.
