Brief Summary
Most leading academic centers including Baylor College of Medicine (BCM) perform deep brain stimulation surgery in the awake patient using microelectrode recording to guide final electrode placement. Microelectrode recording is a means of analyzing the electrical activity of the brain, and assessing whether we have found the target for the deep brain stimulator electrode. However, no evidence exists that microelectrode recording improves patient outcomes. The use of microelectrode recording does extend the duration of surgery and there is evidence to suggest that microelectrode recording may increase the risk of bleeding in the brain during surgery.

Outcome Measures
Primary Outcomes (1)
percentage improvement in the UPDRS part III motor score
The primary outcome measure for this study is the percentage improvement in the Unified Parkinson Disease Rating Scale (UPDRS) part III motor score from baseline to 6 months in patients who receiving stimulation in the "OFF" medication state. Secondary outcome measures include rate of radiographically visible intracranial hemorrhage and changes in neurocognitive function and quality of life testing. The student's two sample t-test will be used to perform the statistically comparisons.
from baseline to 6 months
Study Arms (2)
MER guidance
Will undergo DBS implantation in the awake state using a frame based stereotactic technique and intraoperative microelectrode recording to guide final lead placement.
MRI Guidance
Will undergo DBS implantation under general anesthesia using anatomical targeting in an operating room equipped with an intraoperative MRI to guide electrode placement
Eligibility Criteria
Adult patients between the ages of 30 and 79 Diagnosis of idiopathic Parkinson's disease
You may qualify if:
- Determined to be candidates for subthalamic nucleus (STN) or Globus pallidus (GPi) DBS by consensus recommendation of a multidisciplinary team as evidenced by:
- Ability to provide informed consent as determined by preoperative neuropsychological assessment
- Optimized medically by a neurologist who is an expert in the treatment of movement disorders.
- Persistent motor symptoms which are not effectively controlled with optimal medical management. These symptoms may include levodopa-induced dyskinesias, tremor, or fluctuations in the effectiveness of levodopa throughout the day.
You may not qualify if:
- Dementia
- Previous intracranial surgery
- Intracranial tumor
- Lack of ability to provide informed consent as determined by preoperative neuropsychological assessment
- Medical co-morbidities that would make the patient a poor surgical candidate
