Let's make a difference in our community


The Diversity in Aging Research (DAR) team is committed to advancing science that addresses neurocognitive disparities and promotes neurocognitive health equity in aging. We aim to develop accessible, sustainable, and ethical research that includes and benefits all by focusing our efforts on groups that have been underrepresented in science. We seek to promote an environment that fosters a sense of belonging in science among trainees, staff, and faculty from all backgrounds and allows all to thrive.

Current Studies

This study seeks to understand how Spanish-speaking people living in the US perform cognitive tests (meaning tests of memory and other thinking skills).    You could qualify if:  You are between 60 and 85 years old You are Hispanic or Latino/a Speak Spanish   You will receive the results of your memory tests at no cost to you.  You will also receive payment for your time.  We offer flexible hours to schedule study visits, and all information is confidential and voluntary.  Assistance is available for transportation to study visits.  If you are interested please call us at 919-681-3957 or send us an email to
