Autoimmune Neurology
Upon completion of this program, participants should be able to describe the immunopathogenesis of Aquaporin-4 (AQP4-IgG) antibody–positive Neuromyelitis optica spectrum disorder, including the role of complement-mediated astrocytopathy; apply current diagnostic criteria for NMOSD, including appropriate use and interpretation of AQP4-IgG testing, MRI findings, and supportive clinical features; differentiate NMOSD from multiple sclerosis and other inflammatory, infectious, and vascular myelopathies based on clinical presentation, imaging, and serologic profiles; evaluate acute attack management strategies for NMOSD, including first-line use of high-dose corticosteroids, plasma exchange, and escalation approaches in refractory disease; and develop evidence-based long-term treatment plans for AQP4-IgG–positive NMOSD, incorporating recently approved complement inhibitors and other targeted immunotherapies, while balancing relapse prevention and safety considerations.
