Scientists know that Black people are at a greater risk for health problems like heart disease, diabetes and Alzheimer’s disease than white people. A growing body of research shows that racism in health care and in daily life contributes to these long-standing health disparities for Black communities.
Now, some researchers are asking whether part of the explanation involves how racism, across individual interactions and systems, may physically alter the brain.
“That could be behaviors like, let’s say, a woman clutching her purse as a black man is walking next to her. Or they could be verbal, like someone saying, like… ‘I didn’t expect you to be so articulate,'” says Negar Fani, a clinical neuroscientist at Emory University who studies people experiencing Posttraumatic Stress Disorder, or PTSD.
Recently, Fani has collaborated with Nate Harnett, an assistant professor of psychiatry at Harvard Medical School, to study how the brain responds to traumatic events and extreme stress, including the events and stress related to racism.

Nathaniel G. Harnett, PhD, is a neuroscientist whose research is focused on understanding the brain basis for why some people are more likely to develop stress-related disorders, such as post-traumatic stress disorder (PTSD), after trauma. His current work leverages magnetic resonance imaging (MRI) techniques—including functional MRI, structural MRI, and diffusion weighted imaging—to identify multimodal neural signatures of PTSD susceptibility in the acute aftermath of trauma exposure.
