Pediatric-Onset Multiple Sclerosis: A Single Center Study
Pediatric-onset multiple sclerosis (POMS), once thought to be rare, is now being diagnosed in increasing numbers in children. Despite improvements to diagnostic criteria, the diagnosis and management of POMS remains challenging. The aim of this study is to retrospectively describe a growing POMS patient population seen at a single center over a 13 year period. Epidemiologic, clinical, neuroimaging, laboratory features and therapeutic management and outcome data were collected and analyzed. These data support associations between MS and environmental triggers such as obesity and vitamin D deficiency. Presenting symptoms, magnetic resonance imaging and laboratory findings were consistent with the existing literature; however, the prevalence of cortical lesions and abnormal saccadic pursuit is higher than other reports. Data also demonstrate a shift in practice from first- to second-line therapies over the observed period.
