BACKGROUND HLA-DRB1*15 genotype, previous infection with Epstein-Barr virus, and vitamin D insufficiency are susceptibility factors for multiple sclerosis, but whether they act synergistically to increase risk is unknown. We aimed to assess the contributions of these risk factors and the effect of established precursors of multiple sclerosis, such as brain(More)
OBJECTIVES For most adults with initial clinical presentation of multiple sclerosis (MS), biological disease was likely initiated many years prior. Pediatric-onset MS provides an opportunity to study early disease processes. METHODS Using antigen microarrays, including CNS-related proteins, lipids, and other autoantigens, we studied early immunologic(More)
OBJECTIVE We evaluated the relationship of optical coherence tomography (OCT)-measured ganglion cell layer (GCL) and retinal nerve fiber layer (RNFL) thickness to other functional measures of afferent visual pathway competence including high-contrast visual acuity (HCVA) and low-contrast visual acuity (LCVA), visual field sensitivity, and color vision(More)
The diagnosis of acquired demyelinating syndromes of the central nervous system in children requires exclusion of other acute central nervous system disorders. In a 23-site national demyelinating disease study, standardized clinical, laboratory, and magnetic resonance imaging (MRI) data were obtained prospectively from onset, and serially at 3, 6, and 12(More)
This article reviews the features that should prompt consideration of diseases that mimic acquired demyelinating syndromes and multiple sclerosis using vignettes to highlight unusual clinical and radiologic features. Cases of transverse myelitis, spinal infarction, acute disseminated encephalomyelitis, fever-induced refractory epileptic encephalopathy in(More)
