About this study

In plain language

BLAAC PD studies Parkinson's disease in Black and African American communities. It is for adults with and without Parkinson's disease. The study takes place across the United States and is part of a global project on genes and Parkinson's disease.

BLAAC PD is a research study to understand what Parkinson's disease looks like for Black and African American communities. BLAAC PD is happening at research centers around the United States. The study is part of the Global Parkinson's Genetics Program (GP2). GP2 is a research project working to transform understanding of the genetics of Parkinson's disease and make that knowledge globally relevant.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
