Therapeutic options in neuromyelitis optica spectrum disorders

Abstract

Neuromyelitis optica is a relapsing inflammatory disorder of the central nervous system that manifests predominantly with attacks of optic neuritis and longitudinally extensive transverse myelitis; attacks are often severe. In contrast to multiple sclerosis, a secondary progressive phase is rare, and disability in neuromyelitis optica spectrum disorders is related to relapses. Thus, prompt and effective treatment of relapses, and early initiation of long-term immunosuppression to prevent subsequent attacks is required in order to prevent morbidity and mortality.
