Summary

Deep brain stimulation for Parkinson's disease is a well established therapy. Current practice requires tedious adjustment of stimulation settings based on frequent patient assessments. Ultimately, the goal is to develop a system that can program itself using signals that are recorded directly from the brain on a continuous basis. Our previous work has identified abnormal electrical signals in the brain that are targeted for stimulation that can potentially be used to develop a self-programming system. In this study, the investigators will test the safety and utility of a novel adapted device that can not only deliver stimulation to the brain but also record brain signals in a patient that is implanted with a deep brain stimulation system. The purpose of this Phase I study is to understand the safety of the device as well as the relationship between these electrical signals measured from deep within the brain and Parkinson's symptoms and how these signals can be used to guide a self-programmed system. The study will entail implanting this special device (Activa PC+S) in place of the standard generator (Activa PC) and to compare clinical symptoms, recorded brain signals, and stimulation patterns during a one year period after implantation. Specifically, the investigators will use the Activa PC+S to record GPi (internal globus pallidus) local field potentials between and during programming visits, allowing the surgeon to better characterize a patient's disease. At the same time, the investigators will evaluate the safety of this new device.

DEVICE

Medtronic Activa PC+S Sensing Deep Brain Stimulator Generator

Patients undergoing deep brain stimulation for Parkinson's disease based on clinically indicated criteria will have the option to enroll in this study, in which the Activa PC+S generator and corresponding extension leads will be implanted rather than the standard Activa PC system. Patients will be assessed every month for 3 months and then every 3 months after, including off and on medication assessments.
