About the MS program at Ohio State

Dr. Segal and patient in exam wearing masksThe Multiple Sclerosis (MS) and Neuroimmunology Division within the Department of Neurology at The Ohio State University Wexner Medical Center is one of the most advanced and comprehensive centers for MS care and research in the United States. We’ve brought together world-renowned clinicians, scientists and educators who specialize in MS and related diseases, becoming a destination for patients, as well as for physicians, learners and researchers, from well beyond central Ohio.

We offer the latest disease-modifying therapies, symptomatic treatments and rehabilitative interventions with the goals of preventing relapses and slowing or halting neurological decline. These clinical innovations are only strengthened by a robust research portfolio that includes fundamental studies on the causes of MS and investigator initiated clinical trials of innovative therapies, conducted by a faculty ardently committed to training the next generation of MS specialists and neuroimmunologists.

Program highlights

MS doctor with patient wearing masksCare is coordinated among a multidisciplinary team with specialized knowledge and experience in MS and neuroimmunology. Collaboration strengthens our approach. Depending on the needs of individual patients, the clinical care team may include a neurologist, pharmacist, nurse practitioner, infusion nurse, social worker, neuropsychologist, neuroradiologist, sleep and fatigue specialist, urologist, physical/occupational therapist, speech therapist, psychiatrist and ophthalmologist.

The latest diagnostic tools inform more effective and targeted treatment plans. This includes 3 Tesla MRI, optical coherence tomography, evoked potential tests and rapid onsite laboratory analysis of blood and cerebrospinal fluids. A dedicated network of clinical trial coordinators and internationally recognized research labs studying the pathogenesis of MS and related conditions keep the team at the forefront of medical innovation and knowledge. These efforts are facilitated by a state-of-the- art biorepository with integrated database.

Daily collaboration and active engagement with medical students, neurology residents and MS fellows challenge the entire team to keep informed about the latest clinical advancements and research findings.

We offer an internationally prominent MS research laboratory program investigating the pathogenesis of MS and exploring novel biomarkers and therapeutic targets to increase the accuracy of diagnosis and drive the discovery of superior and safer treatments.

The program is supported by Benjamin Segal, MD, chair of the Department of Neurology, along with an associate professor, six assistant professors and two postdoctoral fellows, as well as a team of technicians and graduate students.
