The GBA Multimodal Study in Parkinson's Disease

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

Source: ClinicalTrials.gov · Last updated 2 Sept 2026

Brief summary (registry, in English)

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 cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • intolerance to antiparkinsonian drug withdrawal (for GBA-PD subjects);
  • ongoing treatment with cholinergic drugs

Other illness

  • co-occurrence of other neurological disorders;

Other

  • severe claustrophobia;

Who the study is looking for

  • heterozygous for a pathogenic GBA mutation (e.g., p.L444P, p.N370S) or polymorphism;
  • age 18 to 80 years.

Age in the registry: 18 years to 80 years · Sex: All · Does not accept healthy volunteers
