ReviewDiagnosis and classification of neuromyelitis optica (Devic's syndrome).
Neuromyelitis optica (NMO) is an autoimmune disorder, predominantly characterized by severe optic neuritis (ON) and transverse myelitis (TM). Historically considered a variant of Multiple sclerosis, the discovery that most NMO patients have autoantibodies against aquaporin-4 (AQP4) or NMO-IgG, dramatically changed our understanding of the disease. ⋯ Furthermore, symptoms other than optic-spinal involvement and the presence of brain lesions, do not exclude the diagnosis of NMO as traditionally accepted. We present an overview of the epidemiology, clinical manifestations and current diagnostic criteria for NMO and NMO spectrum disorders.
