Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals diagnosed with Parkinson's disease for over five years who exhibit cognitive impairment and are eligible for deep brain stimulation.

Probably not a fit

Patients with severe cognitive impairment, psychiatric disorders, or atypical parkinsonism 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 observational study aims to investigate the effects of deep brain stimulation (DBS) and transcranial magnetic stimulation (TMS) on cognitive impairment in patients with Parkinson's disease (PD). Utilizing advanced neuroimaging techniques, the study will analyze structural and functional brain network changes before and after treatment. By examining the relationship between neural regulation and cognitive symptoms, the research seeks to identify optimal stimulation sites and improve clinical outcomes for PD patients. The findings could provide insights into the mechanisms underlying cognitive decline in Parkinson's disease.

Why it matters

Potential benefit: If successful, this study could lead to improved cognitive function in Parkinson's disease patients through targeted brain stimulation techniques.

How similar studies have gone: Previous studies have shown promising results with brain stimulation techniques in improving cognitive symptoms in Parkinson's disease, indicating potential for success in this approach.
