Prospective case-control study compares cognitive and motor outcomes in Parkinson’s disease patients, suggesting limited cognitive benefits from stimulation.
The study suggests that DBS STN does not have a significant additional impact on cognition performance in PD patients. Our results also suggest that while active DBS STN continues to improve motor symptoms, it did not prevent the longitudinal worsening of OFF-motor severity (UPDRS III OFF), which progressed similarly in both groups.
