The GBA Multimodal Study in Parkinson's Disease
Recruiting now NCT04101968
Run by Pacific Parkinson's Research Centre · for 18 to 80 · All sexes
What this study is about
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 (things the study team will check)
✅ You may be able to join if…
- heterozygous for a pathogenic GBA mutation (e.g., p.L444P, p.N370S) or polymorphism;
- age 18 to 80 years.
🚫 You may not be able to join if…
- co-occurrence of other neurological disorders;
- implants that contraindicate the MRI scanning (e.g. cardiac pacemaker, ferromagnetic implants or devices);
- severe claustrophobia;
- intolerance to antiparkinsonian drug withdrawal (for GBA-PD subjects);
- ongoing treatment with cholinergic drugs
