Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 40 and older who are scheduled for deep brain stimulation surgery at Vanderbilt University Medical Center and have a diagnosis of Parkinson's disease.

Probably not a fit

Patients under 40 years old or those with movement disorders other than Parkinson's disease 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 study aims to investigate the brain activity associated with cognitive impairment in patients with Parkinson's disease. By utilizing neural recordings from corticostriatal structures during deep brain stimulation surgery, researchers will measure the neural activity that underlies nonmotor symptoms of the disease. The approach involves direct observation of brain function in a clinical setting, providing valuable insights into the cognitive aspects of Parkinson's disease.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment options for cognitive impairment in Parkinson's disease patients.

How similar studies have gone: While there have been studies on deep brain stimulation and Parkinson's disease, this specific focus on cognitive impairment through neural recordings is relatively novel.
