What is Devic's disease?
Devic's disease, also called neuromyelitis optica or NMO, is an immunological disorder that may be confused with multiple sclerosis (MS). Devic's disease is often characterized by immune attacks on the optic nerves (which transmit what you see to your brain) and the spinal cord. Patients may experience these attacks at the same time or at different times. They may also have just problems with the optic nerves alone or just problems with the spinal cord alone and still have Devic's disease.
