Hamid SHM, et al. - The researchers performed this study to compare the prevalence of seizures and encephalitis-like presentation, or both between aquaporin 4 antibody (AQP4-IgG)–positive and myelin oligodendrocyte glycoprotein IgG (MOG-IgG)–positive patients. Compared to patients with AQP4-IgG–associated disease, patients with MOG-IgG–associated disease were more likely to have seizures and encephalitis-like presentation.
