<unk> , also known as<unk> 's syndrome or neuromyelitis optica (NMO), is an autoimmune, inflammatory disorder in which a person's own immune system attacks the optic nerves and spinal cord. This produces an inflammation of the optic nerve (optic neuritis) and the spinal cord (myelitis). Although inflammation may also affect the brain, the lesions are different to those observed in the related condition multiple sclerosis. Spinal cord lesions lead to varying degrees of weakness or paralysis in the legs or arms, loss of sensation, and/or bladder and bowel dysfunction.<unk>  is a rare disorder which resembles multiple sclerosis (MS) in several ways, but requires a different course of treatment for optimal results.. The likely target of the autoimmune attack at least in some patients with NMO has been identified. The target is a  protein of the nervous system cells called aquaporin 4.
