What this research studies

If you join, you'll have noninvasive retinal scans (OCTA), brain MRIs, and blood draws over time to look for signs of small-vessel damage that can affect thinking and memory. The USC team will follow at least 200 people in the Los Angeles area from different ethnic backgrounds, with an emphasis on enrolling African American and other underrepresented groups. USC is working with several other sites as part of the MarkVCID consortium to make sure the same tests work across clinics. Your scans and blood samples could help link eye, blood, and brain changes to cognitive decline.

Who could benefit from this research

Good fit: Ideal participants are adults with risk factors for small-vessel disease or early memory concerns, especially African American and other underrepresented individuals who live near Los Angeles.

Not a fit: People whose memory problems are known to be caused by nonvascular conditions may not receive direct benefit from these biomarkers.

Why it matters

Potential benefit: If successful, these tests could help detect small-vessel-related cognitive problems earlier and improve monitoring of disease over time.

How similar studies have performed: Earlier phases of the MarkVCID consortium and pilot studies have shown promising signals for these retinal and blood markers, but full multi-site clinical validation is still under way.
