Multiple Sclerosis Symptoms and Causes
Multiple sclerosis (MS) is a chronic disease of the central nervous system that is thought to be an autoimmune disorder. It is an unpredictable condition that can be relatively benign, disabling or devastating. Some individuals with multiple sclerosis may be mildly affected while others may lose their ability to write, speak or walk when communication between the brain and other parts of the body becomes disrupted. Multiple sclerosis symptoms are many and varied and may include symptoms such as: numbness or weakness in one or more limbs, partial or complete loss of vision, double vision or blurring of vision and tingling or pain in parts of the body. The causes of multiple sclerosis are unknown. It's believed to be an autoimmune disease, in which the body's immune system attacks its own tissues. In multiple sclerosis, this process destroys myelin—the fatty substance that coats and protects nerve fibers in the brain and spinal cord.
