Devic's disease, or neuromyelitis optica, (NMO) is a type of inflammatory demyelinating disease. A demyelinating disease occurs when the myelin sheath, a protective covering that surrounds brain and spinal cord nerves is damaged.In the case of Devic's disease, the patient develops myelitis (inflammation of the spinal cord) and optic neuritis (inflammation of the optic nerve).
