Adys Mendizabal, MD, MS, is an assistant professor in the Department of Neurology at the University of California, Los Angeles (UCLA). She earned a Bachelor of Science in Psychobiology from the University of Miami and completed medical school at the Lewis Katz School of Medicine at Temple University. While in medical school, she also earned a Master of Arts in Urban Bioethics, focusing on social determinants of health in urban communities. She completed her neurology residency at the Hospital of the University of Pennsylvania and movement disorders fellowship at UCLA. She also completed a Master of Science in Health Policy and Management from the Fielding School of Public Health at UCLA.

Dr. Mendizabal's research focuses on health services in neurology. Health services is a field that studies how patients access care, assess healthcare outcomes and use this information to shape healthcare policy. One focus of health services research is evaluating the role of social determinants of health in a person’s ability to access healthcare and how they could lead to differences in health outcomes. Dr. Mendizabal’s current research ooks at racial and ethnic disparities in Huntington’s Disease (HD), a rare progressive neurogenetic condition. She’s also developing projects improving sociodemographic data collection in HD, with the goal of understanding how minoritized groups with HD access specialized care, and with the ultimate goal to ensure equitable access to specialized care for HD and other neurological disorders. She hopes to use these methods to enhance the study of health services in other rare genetic conditions. In addition to research on Huntington’s Disease, her work also looks at the relationship between Adverse Childhood Experiences (ACEs) and healthcare outcomes in adults with neurological diseases.

In addition to her research work, she is actively involved in health equity efforts at UCLA and nationally. She's a member of the American Neurological Association (ANA) inclusion, diversity, equity, anti-racism, and social justice committee (IDEAS), has implemented neurology residency health equity curriculums at the Hospital of the University of Pennsylvania and UCLA, and currently serves as the faculty lead for the EDI-Advocacy neurology residency educational track.
