Parkinson's Progression Markers Initiative Online Study (PPMI Online)

Parkinson Progression Marker Initiative Online (PPMI Online) is an observational study collecting participant reported information from people with and without Parkinson's disease (PD), for the goal of better understanding risk and predictive factors for PD.

PPMI Online is part of the broader Parkinson Progression Marker Initiative aimed at identifying markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability.

Detailed Description

PPMI is a broad program that is expanding the goals of the original PPMI study, and will include this PPMI Online protocol, as well the PPMI Clinical [NCT04477785], PPMI Remote, PPMI Digital protocols (with external regulatory oversight). All participants in PPMI may be asked to participate in one or all of these protocols and their enrollment in these studies may occur in varying order. PPMI participants may also be asked to participate in additional PPMI companion studies (as they are developed), which may only involve a subset of PPMI participants based on their cohort designation
