Pediatric acquired demyelinating syndromes: updates in diagnosis, testing, and management.

Purpose Of Review: To highlight the clinical presentation, diagnostic approach, and management of acquired inflammatory demyelinating syndromes in children.

Recent Findings: The identification of myelin oligodendrocyte glycoprotein antibody-associated disease in 2017 and evolving evidence regarding best practices for management has had a significant impact on pediatric neuroimmunology, as has the shift in treatment of pediatric-onset multiple sclerosis, with the use of high-efficacy disease-modifying therapies early in the disease course.

Summary: With expanding awareness and growing interest in pediatric onset neuroinflammatory conditions, the number of children diagnosed with acquired demyelinating syndromes is rising. It is critical to refine our understanding of the underlying pathophysiological mechanisms in these disorders to provide the most effective care. Much of our practice continues to be modeled on adult care, and further large-scale pediatric studies are necessary to explore the natural history and assess the safety and efficacy of immunotherapies in childhood-onset demyelinating diseases.
