multiple sclerosis
A disorder of the central nervous system marked by weakness, numbness, a loss of muscle coordination, and problems with vision, speech, and bladder control. Multiple sclerosis is thought to be an autoimmune disease in which the body's immune system destroys myelin. Myelin is a substance that contains both protein and fat (lipid), serving as a nerve insulator and helping in the transmission of nerve signals.

Multiple sclerosis (MS)
The National Multiple Sclerosis Society says of MS that it is "a disease that randomly attacks your central nervous system, wearing away the control you have over your body. Symptoms may range from numbness to paralysis and blindness. The progress, severity and specific symptoms cannot be foreseen. You never know when attacks will occur, how long they will last, or how severe they will be. Most people are diagnosed with MS between the ages of 20 and 40...." In medical terms, MS involves demyelinization of the white matter sometimes extending into the gray matter. Demyelinization is loss of myelin, the coating of nerve fibers composed of lipids (fats) and protein that serves as insulation and permits efficient nerve fiber conduction. The "white matter" is the part of the brain which contains myelinated nerve fibers and appears white, whereas the gray matter is the cortex of the brain which contains nerve cell bodies and appears gray. When myelin is damaged in MS, nerve fiber conduction is faulty or absent. Impaired bodily functions or altered sensations associated with those demyelinated nerve fibers give rise to the symptoms of MS. Recent research (1998) has also identified nerve cell death as part of the nervous system injury in MS.

multiple sclerosis
a disease characterized by hardened plaques on the brain and spinal cord. MS can cause paralysis, tremors, and speech and vision disturbances. It typically occurs in early adulthood, and is characterized by exacerbations and remissions. MS has been associated with human herpesvirus 6 (HHV-6) infection.

Multiple sclerosis
Multiple sclerosis (abbreviated MS, also known as disseminated sclerosis or encephalomyelitis disseminata) is a chronic, inflammatory, demyelinating disease that affects the central nervous system (CNS). MS can cause a variety of symptoms, including changes in sensation, visual problems, muscle weakness, depression, difficulties with coordination and speech, severe fatigue, cognitive impairment, problems with balance, overheating, and pain. MS will cause impaired mobility and disability in more severe cases.
