PPMI online has been designed to capture your data securely online, over time, using the internet. While in the study, you will answer questions related to your demographics and health that may be related to your risk of developing Parkinson’s. Depending on the information you provide, you may also be invited to answer different questions and to visit a medical clinical for additional testing. Participants in PPMI online may also be asked to participate in additional PPMI studies as they are developed. PPMI is sponsored by the Michael J. Fox Foundation for Parkinson’s Research.
