Antibody-mediated encephalitides: distinct diseases with transdisciplinary implications.

Antibody-mediated glial disorders targeting aquaporin-4 and myelin oligodendrocyte glycoprotein are distinct nosological entities with specific targets, mechanisms, syndromes, and treatment implications.

• Why it matters: Immune-mediated neurological conditions were previously treated as idiopathic, and pooling diverse neuronal antibody disorders can obscure differences that matter for diagnosis and therapy.
• What they did: The work contrasts glial antibody-mediated diseases with neuronal autoimmune encephalitides, using anti-NMDA receptor encephalitis, anti-LGI1 encephalitis, and anti-IgLON5 disease to highlight differences in demographics, triggers, mechanisms, clinical features, post-acute course, and treatment needs.
• The result: Recognizing autoimmune encephalitides as distinct entities supports coordinated multidisciplinary care, improving recognition of new diseases and enabling more targeted therapeutic development.
