Neuromyelitis optica spectrum disorders / 中华神经科杂志

Neuromyelitis optica spectrum disorders (NMOSD) is an immune mediated inflammatory demyelinating disease of the central nervous system. Optic neuritis and longitudinally extensive transverse myelitis are the main clinical signs, and the etiology is mainly related to aquaporin 4 (AQP4) antibody. AQP4 is the target antigen of immune attack. NMOSD is characterized by optic neuritis, longitudinally extended transverse myelitis, medulla area postrema syndrome, brainstem syndrome, diencephalic syndrome and cerebral syndrome. In recent years, the etiological mechanism, clinical diagnosis and monoclonal antibodies targeting new mechanisms of NMOSD have made great progress, which promoted the development of clinical neurology.
