Research Focus
Dr. Ihab M. Hajjar's research lab at UT Southwestern Medical Center focuses on understanding how COVID-19 affects the brain, especially in older African Americans. They investigate long-term cognitive issues that some people face after recovering from the virus, examining factors like age, health conditions, and brain imaging. The goal is to better identify those at risk and improve healthcare outcomes for vulnerable populations.
