Nearly three million people worldwide are living with multiple sclerosis (MS), affecting individuals from diverse geographical, ethnic, racial, and socio-economic backgrounds. This diversity raises important questions about how these factors may influence the experiences and outcomes of those with MS, as well as whether research studies and clinical trials have sufficiently addressed this variability. To answer these questions and more, host Brett Drummond of MSTranslate speaks with two leading researchers in this field: Dr. Léorah Freeman, assistant professor at the Dell Medical School Department of Neurology, The University of Texas at Austin; and Dr. Lilyana Amezcua, Associate Professor of Clinical Neurology at the University of Southern California's Keck School of Medicine.
