Rebecca Whitney of SRNA was joined by Dr. Jayne Ness and Dr. Silvia Tenembaum for an ABCs of NMOSD podcast entitled, "Pediatric NMOSD - History and Diagnosis, Part I." The experts begin by explaining the history of pediatric NMOSD, including the first known cases and a research paper that was published on the subject. They then discuss how common NMOSD is in pediatric patients and the diagnostic tests used for NMOSD. The experts compare NMOSD and MOGAD in children, including antibody levels, disease course, and treatment protocol. Finally, the experts provide information on differential diagnoses and prognosis.
