Dear PPMI Participant, Thank you for your wonderful contribution to Parkinson’s research. As a person with Parkinson’s, I have hope for the future because perhaps this trial will lead to significant results that could benefit millions. Thanks to your generosity, we will learn from this research, whatever the outcome. Please know that your volunteerism is greatly appreciated! Al Person with Parkinson’s “I see a common thread among those who live with this disease: a need to understand, a drive to see a cure, and always, a desire to help speed progress.” Andrew Siderowf, MD, MSCE PPMI Scientific Advisory Board 11
