Cleveland Clinic’s Pediatric MS study group is led by Co-PIs Mary Rensel, MD and Gary Hsich, MD. They are on the steering committee of the National Network of Pediatric MS Centers, 12 centers sponsored by the National MS Society (NMSS) involved in specialized clinical care and research for pediatric MS. There is a national database of pediatric-onset demyelinating disorders enrolling participants since 2009. Additional projects include a puberty and obesity study, a nutritional study, and an environmental and genetic study. A 7T MRI project is recruiting patients to assess brain volume in Pediatric MS with the PI Kedar Mahajan, MD and Neuroradiology at Cleveland Clinic. We are starting our first treatment protocol for Pediatric MS in one month. We also have secured funding to look at No Evidence of Disease Activity (NEDA) in Pediatric MS on a project with our fellow Jenny Feng, MD as PI.

Pediatric MS Research has been presented as a poster at the 2019 AAN, 2019 ECTRIMS, and 2019 Child Neurology meeting.
