Neuromyelitis Optica Spectrum Disorder
- What it is
Neuromyelitis optica spectrum disorder (NMOSD) is a chronic immune mediated condition, in which the body’s immune system mistakenly attacks the central nervous system. People with NMOSD often develop inflammation of the nerves of the eyes or optic nerves (optic neuritis), of the spinal cord (transverse myelitis), or sometimes of the brain.
