Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators will also determine whether magnetic resonance imaging (MRI) network methods, which are less invasive and more broadly available than positron emission tomography (PET), produce comparable network progression measurements in individual patients. These determinations will be critical for the design of clinical trials of new disease-modifying drugs.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Parkinson's disease (PD) glucocerebrosidase (GBA) carriers
Parkinson's disease subjects with GBA mutation
DNA/GeneticTesting
Subjects will be tested for GBA and LRRK2 mutation status at baseline.
FDG PET scan
18F-Fluoro-2-deoxy-glucose (FDG) PET scan is a nuclear medicine test that measures glucose metabolism (energy) in your brain at baseline and 18 months later.
MRI scan
Magnetic Resonance Imaging (MRI) is a noninvasive scan which produces detailed pictures of the brain using a magnetic field. In addition, a special type of MRI, called resting state functional MRI (rs-fMRI), will measure and map brain activity. Conducted at baseline and 18 months later.
Clinical and neuropsychological assessments
Investigator will evaluate subjects according to the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), the standard clinical tool used to measure the severity and progression of PD. Neuropsychological evaluation will assess how one's brain functions (via pencil and paper testing), which indirectly yields information about the structural and functional integrity of the brain. Conducted at baseline and 18 months later.
Parkinson's disease (PD) non glucocerebrosidase (GBA) carriers
Parkinson's disease subjects without GBA mutation
DNA/GeneticTesting
Subjects will be tested for GBA and LRRK2 mutation status at baseline.
FDG PET scan
