Deep Brain Stimulation (DBS) Data Base Study
Deep Brain Stimulation (DBS) Data Base Study
The primary goal of this study is to evaluate and compare outcomes, trends, and effectiveness
 of both awake and asleep Deep Brain Stimulation (DBS) surgical treatments, target selection,
 targeting accuracy and outcomes in patients with Parkinson's disease and Essential tremor.
Deep Brain Stimulation (DBS) surgery is a treatment that can improve some of the motor
 symptoms associated with several movement disorder diseases. DBS is recommended for patients
 with Parkinson's disease who respond well to medication, but still experience frequent
 wearing off of medications with return of symptoms. Patients may also be experiencing
 troubling medication side effects such as dyskinesias, sleepiness, hallucinations, confusion,
 and behavioral/personality changes. DBS is also used for patients with Essential tremor who
 have undergone long trials of medication therapy and are still symptomatic. The goal of DBS
 surgery is to capture that best response to medication and hold it through the day. The Food
 and Drug Administration (FDA) approved DBS as a treatment for essential tremor in 1997 and
 for Parkinson's disease in 2002.

 The goal of DBS surgery is to improve the quality of life of patients and their families by
 reducing motor symptoms such as slowness, stiffness and tremor and possibly reducing
 medication. In order to help with our understanding of its effects, we will collect
 information on patients who will be undergoing or have undergone DBS surgery.

 St. Joseph's Hospital and Medical Center / Barrow Neurological Institute is one of only a few
 hospitals in the United States offering a new procedure known as asleep DBS surgery,
 performed under general anesthesia, as well as the traditional awake DBS procedure; therefore
 it is important that this new asleep surgery option be studied and compared to awake DBS
 surgery.

 Objectives include:

 -  Comparison of data collected for both the awake and asleep DBS procedures during the
 pre-operative and post-operative periods including testing, diagnosis, surgical
 treatment, target accuracy, complications, motor function and quality of life outcomes.

 -  Comparison of the differential effects of STN and GPi DBS on gait and balance control

 -  Investigate the effects of DBS on the saccadic eye movements.
Inclusion Criteria:

 Exclusion Criteria:

 -  Clinical diagnosis for Parkinson's Disease or Essential Tremor
