The Parkinson Progression Marker Initiative (PPMI) is a study to learn more about Parkinson's disease (PD) by observing people over time. It looks at how PD changes in patients and tries to find markers or signs that show how the disease progresses. This information can help in developing treatments to slow down PD. Participants can include people with Parkinson's, those who might develop it (prodromal), and healthy controls. The study involves various tests like imaging and biological assessments.
Key Points:- Eligibility: Participants need to meet specific age and health criteria, and they should be able to give informed consent.
- Commitment: Involves multiple visits for imaging and other tests, possibly across different parts of a larger study program.
- Exclusions: People with certain medical conditions or who have taken specific medications recently may not be eligible.
