This study, called GBPDC, is looking into how the connection between your gut and brain (the gut-brain axis) might be involved in Parkinson's disease (PD). Researchers want to understand how this connection changes in people with PD, those at risk for PD, and those without the disease. They will compare different groups of people based on their PD status and severity. The study aims to collect information and samples over 24 months to better understand PD and potentially find new ways to diagnose or treat it. You might be able to join if you are between 21 and 80 years old and have a clinical diagnosis of PD, or if you are at risk for PD, or do not have PD.

Compensation

Not stated in the trial record.

Follow-up

Participants will be observed for up to 24 months to assess GI influences on PD and co-associations components of the gut-brain axis.
