Multiple sclerosis (MS) is a chronic disease that affects the central nervous system. While researchers don't know the exact cause of MS, they do believe that the disease is the result of an abnormal immune system response.
MS affects a person's neurons, the cells in the brain and spinal cord that are responsible for transmitting information and creating thought. These cells are coated in a myelin sheath, which helps the cells carry electrical signals. In people with MS, this myelin sheath is gradually destroyed in a process known as demyelination.
