Study Summary
Prospective trial of low frequency deep brain stimulation of the ventral subthalamic nucleus to improve cognitive performance in patients with advanced Parkinson's disease. All study participants have undergone DBS implantation surgery as part of their routine care for motor manifestations of Parkinson's disease. In this study, a temporary low frequency period of stimulation will be applied to determine its effects on cognition.
Primary Outcome
The Stroop Color and Word Test (SCWT) is a neuropsychological test extensively used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute, well-known as the Stroop Effect.
Interventions
- DEVICE deep brain stimulation
