Deep Brain Stimulation (DBS) for Early Stage Parkinson's Disease (PD)

Deep brain stimulation (DBS) of both the right and left sub-thalamic nucleus (STN) is an FDA approved treatment for advanced PD. In mid- and advanced stage Parkinson's disease, using DBS in this area of the brain lessens symptoms and allows patients to take less drug to control the disease. Dosage and frequency are not applicable to the DBS. Once the DBS is placed, unless deemed necessary, it will not be removed.

The drugs used on this study are not investigational. They are drugs for Parkinson's disease that are standard of care. The drug form, dosage, frequency and duration will vary. Examples of drugs used include carbidopa/levodopa, pramipexole, ropinirole, and selegiline.
