Is this trial a fit for you?

Likely a good fit

Ideal candidates include Black or African American individuals aged 18 years or older, either diagnosed with Parkinson's disease or without any neurological conditions.

Probably not a fit

Patients who do not identify as Black or African American or those with a diagnosis of Parkinson's disease or other neurological conditions may not benefit from this study.

What this trial studies

BLAAC PD is an observational study aimed at exploring the genetic factors associated with Parkinson's disease specifically in Black and African American populations. Participants will provide blood or saliva samples, undergo a smell test, and may participate in a physical exam during a single visit at various research centers across the United States. This initiative is part of the Global Parkinson's Genetics Program, which seeks to enhance the understanding of Parkinson's disease genetics and its implications for diverse communities. The findings could lead to improved diagnostic tools and treatments tailored for Black and African American individuals affected by Parkinson's disease.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and treatment options for Parkinson's disease in Black and African American patients.

How similar studies have gone: While studies have explored genetic factors in Parkinson's disease, this specific focus on Black and African American populations is novel and addresses a significant gap in existing research.
