The GBA Multimodal Study in Parkinson's Disease (NCT04101968)

Multimodal Molecular Imaging and Biometric Analysis in GBA-PD and Asymptomatic GBA-mutation Carriers

🟢 Recruiting Interventional Protocol 📊 Observational Clinical Research Sponsor: Pacific Parkinson's Research Centre

🩺 Plain-English Summary (8th-Grade Level)

This study plans to analyze the molecular and clinical mechanisms of the relationship between the GBA mutations and Parkinson's disease. This will be assessed through the use of advanced neuroimaging techniques called PET (positron emission tomography) to study the accumulation of the tau protein and the dysfunction of acetylcholine and dopamine in the brain of people with a mutation in the GBA gene, with and without Parkinson's disease. The ingestigators will also use a technology-based assessment to study the typing patterns as possible biomarkers of early motor dysfunctions.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (2 items) and avoid the listed exclusions (6 items).

Location: Oregon Health & Science University — Portland, Oregon

Age range: 18 Years to 80 Years
