Summary

This trialwill test if stimulating the brain with low frequency in Parkinson's patients can improve their cognitive control.

Who is the study for?
This trial is for adults with advanced Parkinson's Disease who have had a specific type of deep brain stimulation (DBS) surgery using the Boston Scientific VerciseTM system. They must be able to consent, participate in cognitive tests, and not have severe cognitive or physical impairments.
What is being tested?
The study is testing low frequency stimulation of the ventral STN alongside standard high frequency stimulation of the dorsal STN in patients with Parkinson's. It aims to see if this can improve cognition without worsening motor symptoms.
What are the potential side effects?
Potential side effects may include changes in mood or behavior, headache, dizziness, difficulty concentrating, and other neurological effects related to DBS adjustments.
