Neuromyelitis optica (NMO) is a central nervous system disorder that primarily affects the eye nerves (optic neuritis) and the spinal cord (myelitis). NMO is also known as neuromyelitis optica spectrum disorder or Devic’s disease. It occurs when your body’s immune system reacts against its own cells in the central nervous system, mainly in the optic nerves and spinal cord, but sometimes in the brain.
The cause of neuromyelitis optica is usually unknown, although it sometimes appears after an infection, or it can be associated with another autoimmune condition. Neuromyelitis optica is often misdiagnosed as multiple sclerosis (MS) or perceived as a type of MS, but NMO is a distinct condition.
Neuromyelitis optica can cause blindness in one or both eyes, weakness or paralysis in the legs or arms, Painlessful spasms, loss of sensation, uncontrollable vomiting and hiccups, and bladder or bowel dysfunction from spinal cord damage. Children can have confusion, seizures or coma with NMO. Neuromyelitis optica flare-ups might be reversible, but they can be severe enough to cause permanent visual loss and problems with walking.
