Back

Neuromyelitis optica (nmo), also known as devic's disease or devic's syndrome, is a heterogeneous condition consisting of the simultaneous inflammation and demyelination of the optic nerve (optic neuritis) and the spinal cord (myelitis).

SYMPTOMS

People who develop optic neuritis should not drive a vehicle due to reduced vision. They may also develop symptoms in the spinal cord from a process called transverse myelitis (tm) including: altered sensations, with sensitivity to temperature, numbness, tingling, and a sensation of coldness or burning.

CAUSES

The two types of devic's disease, or neuromyelitis optica (nmo) are relapsing nmo and monophasic nmo, and the type depends on the frequency of attacks. Symptoms can include a temporary loss of eyesight, eye pain, and altered sensations in the limbs. The cause is unknown, and there is no cure.
