A chronic degenerative disease of the central nervous system in which gradual destruction of myelin occurs in the brain or spinal cord or both, interfering with the nerve pathways and causing muscular weakness, loss of coordination, and speech and visual disturbances. It occurs chiefly in young adults and is thought to be caused by a defect in the immune system that may be of genetic or viral origin.
