Introduction

Neuromyelitis optica spectrum disorder is a rare autoimmune inflammatory disorder affecting the optic nerves and spinal cord, often associated with antibodies against aquaporin-4 or myelin oligodendrocyte glycoprotein. The disease can cause severe relapses leading to vision loss and neurological disability if not effectively controlled.

Historically, treatment relied on general immunosuppressants, but targeted biologic therapies now play a central role in relapse prevention. These therapies selectively block immune pathways involved in NMOSD pathogenesis. In USA, treatment approaches are shifting toward precision immunotherapy supported by antibody profiling and relapse-risk assessment. Advances in neuroimmunology research are improving therapeutic targeting and outcomes.
