Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 years old who are planning to undergo DBS surgery for Parkinson's Disease.

Probably not a fit

Patients with uncorrected visual or hearing impairments, claustrophobia, or those with non-MRI compatible implants may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This research aims to identify MRI-based brain biomarkers that predict how individuals with Parkinson's Disease respond to Deep Brain Stimulation (DBS) and to assess cognitive changes associated with the procedure. A total of 55 participants with Parkinson's Disease, who are scheduled for DBS, will undergo a series of visits including screening, MRI scanning, and cognitive assessments. Additionally, control participants without Parkinson's Disease will also be recruited for comparative MRI and cognitive evaluations. The study seeks to understand factors contributing to cognitive decline post-DBS, which could enhance patient selection and optimize stimulation targets.

Why it matters

Potential benefit: If successful, this study could lead to improved patient selection for DBS surgery and strategies to minimize cognitive side effects.

How similar studies have gone: While there is existing research on DBS and cognitive outcomes, this specific approach focusing on MRI biomarkers is relatively novel.
