Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The study aims to investigate cognitive impairment associated with Deep Brain Stimulation (DBS) in Parkinson's Disease patients, with a focus on identifying neurophysiology biomarkers of DBS associated cognitive changes. Using neurophysiology data recorded during DBS surgeries and post-implantation, the research intends to identify biomarkers in order to optimize electrode placement, enhance programming, and ultimately minimize DBS-related cognitive side effects.
