Neuromyelitis optica, also known as Devic disease, is an autoimmune disorder that affects the spinal cord and optic nerve. This atypical demyelinating syndrome can be difficult to diagnose and responds poorly to treatments that are used for multiple sclerosis, a similar demyelinating disease. This article discusses the epidemiology, pathophysiology, clinical presentation, latest diagnostic criteria, and treatment options for neuromyelitis optica and neuromyelitis spectrum disorders.
