In Multiple Sclerosis, inflammation of nervous tissue causes the loss of myelin, a fatty material that acts as a sort of protective insulation for the nerve fibers in the brain and spinal cord. This demyelination leaves multiple areas of scar tissue (sclerosis) along the covering of the nerve cells, which disrupts the ability of the nerves to conduct electrical impulses to and from the brain, producing the various symptoms of multiple Sclerosis.
