We don't know what causes MS, but there are certain factors that may increase the risk or trigger its onset. And this is characterized by attacks, or relapses. When you read about multiple sclerosis, you may hear about different types - the most frequent being relapsing-remitting multiple sclerosis. This happens very slowly, usually over decades and typically shows up as gradual walking difficulty happening over several years. But if part of the brain or spinal cord has been damaged by MS, the nerve cells in that area will die off faster than the areas around it that are normal. Now everyone loses brain cells and spinal cord cells as they get older. The resulting damage leaves lesions or scars, and this is where the name comes from: multiple sclerosis, multiple scars. The body can repair damage to the myelin sheath, but it's not perfect. The nerve fibers themselves might also be damaged. When that covering is damaged, it exposes the actual nerve fiber, which can slow or block the signals being transmitted within it.
And this sheath is often compared to the insulation on an electrical wire. Multiple sclerosis is a disorder in which the body's immune system attacks the protective covering of the nerve cells in the brain, optic nerve and spinal cord, called the myelin sheath. Whether you're looking for answers about your own health or that of someone you love, we're here to provide you with the best information available. What is it? Who gets it? The symptoms, diagnosis, and treatment. In this video, we'll be covering the basics of multiple sclerosis. Oliver Tobin, a neurologist specializing in multiple sclerosis at Mayo Clinic.
