Investigation of Non-Invasive Outcomes Predictors in Patients Undergoing DBS for Movement Disorders

The purpose of the study is to determine if non-invasive measurements of brain waves from the
skin called electroencephalography (EEG) can predict whether the brain stimulator will help
your symptoms. Our goal is to obtain these brain wave measurements with patients both awake
and under general anesthesia, and then to evaluate which brain wave patterns are associated
with clinical improvement to determine if they could be useful for predicting whether the
surgery will work. If such predictive measures were established based upon the findings of
this study, they could be used in the future to improve surgical outcomes in the following
ways: (1) to help guide surgical targeting in the operating room awake or under anesthesia,
(2) to guide post-operative programming in clinic, and (3) and to develop potential feedback
systems for "automatic" programming of the brain stimulator system at home.
