"In a world that increasingly recognizes the crucial role of equitable health care, it remains concerning how little is known about the health disparities faced by LGBTQ+ people," said study author Shufan Huo, MD, PhD at the Yale School of Medicine in New Haven, Connecticut. "Our study looked at this group, which has been historically underrepresented in neurological research, and found that they had an increased risk of adverse brain health outcomes." For the study, researchers evaluated data from 393,041 people with.
