What this trial studies

This observational study aims to utilize PET/MR imaging techniques that target TSPO to investigate the changes in neuroinflammation associated with Multiple System Atrophy (MSA). It focuses on both the cerebellar and parkinsonian subtypes of MSA, assessing the potential of neuroinflammation as a biomarker for diagnosing, determining disease severity, and predicting prognosis. The study includes patients aged over 35 who have been clinically diagnosed with MSA and have ruled out other genetic conditions. Participants will undergo neuroimaging to gather data on the temporal and spatial characteristics of neuroinflammation in MSA.

Who should consider this trial

Good fit: Ideal candidates are individuals over 35 years old with clinically confirmed or probable MSA who have excluded polyQ diseases.

Not a fit: Patients who are pregnant, breastfeeding, or have other neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance diagnostic accuracy and treatment strategies for patients with Multiple System Atrophy.

How similar studies have performed: While the approach of using PET imaging for neuroinflammation is established, the specific application to MSA is relatively novel and less explored.
