What this trial studies

This project aims to enhance our understanding of neuroplastic changes in the cortex and subthalamic nucleus of individuals with Parkinson's disease (PD) and how these changes relate to motor and non-motor symptoms. Utilizing advanced neuroimaging techniques such as 7T MRI and non-invasive brain stimulation methods like TMS, the study will quantify structural and functional brain changes. Participants will undergo quantitative assessments of motor and neuropsychological functions at baseline and again after 30-36 months to evaluate disease progression and intervention efficacy.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with idiopathic Parkinson's disease who are not currently receiving levodopa or dopamine agonist treatment.

Not a fit: Patients with dementia or significant neurological disorders, as well as those with a history of severe mood disorders, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection and monitoring of Parkinson's disease progression.

How similar studies have performed: Other studies have shown promise in using neuroimaging and neurostimulation techniques to understand neuroplasticity in neurological conditions, suggesting potential for success in this approach.
