Step-by-step explanation:
Devic's disease, or neuromyelitis optica (NMO), is an autoimmune disease of the central nervous system that primarily affects the optic nerves and spinal cord. It is characterized by inflammation and demyelination, which disrupts the normal functioning of these structures. Symptoms of NMO include visual disturbances, weakness or paralysis of the limbs, sensory disturbances, and bladder and bowel dysfunction. Treatment typically involves immunosuppressive therapy to reduce inflammation and prevent relapses.
