Multiple Sclerosis can present in a variety of different ways, often making diagnosis challengin. In this week’s episode, I interview Dr. Salim Chahin, a neurologist here at Washington University who specializes in the treatment of patients with Multiple Sclerosis (MS). We discuss how to evaluate a patient with suspected MS using a case of optic neuritis. Dr. Chahin went to medical school in Damascus University School of Medicine in Damascus, Syria. He completed a residency in Neurology at the University of Iowa Hospital and completed a fellowship in MS at the University of Pennsylvania. He is a faculty member in the MS department here at Washington University.
