Summary
Every year, approximately 9,000 Parkinson disease (PD) patients undergo deep brain stimulator (DBS) placement into the subthalamic nucleus (STN-DBS). Studies suggest that PD patients with mutations in the glucocerebrosidase (GBA) gene are at high risk for cognitive impairment and approximately 10-17% of subjects undergoing DBS carry GBA mutations. There may be an interaction between STN-DBS, which also impairs cognitive function, and GBA, resulting in worsened cognitive function. This project will 1) determine the relationship between GBA mutation status and post-operative STN-DBS cognitive function, 2) broaden genotype-phenotype relationships of GBA mutation carriers and 3) provide scientific knowledge regarding the longitudinal cognitive effects of DBS in GBA mutation carriers through repeated neuropsychological testing.
