I have Multiple Sclerosis, MS for short.
What does that mean? Well, sclerosis means scars, so literally it means “multiple scars.” But where are those scars? In my brain and on my spinal cord.
MS means that the myelin sheath has been destroyed in some parts of my nervous system. Picture an electrical cord or a stereo wire: there are wires inside of a plastic sheath, right? In your body, that sheath is made of a fatty substance called myelin. Its presence helps the nerves to transmit their electrical impulses correctly. When myelin gets damaged, scars form on your brain or spinal cord and the messages traveling down those specific nerves get thrown out of whack.
Scientists believe that MS is an autoimmune disease, that tiny Pac-Man guys produced by my own body are nibbling at my spinal cord and brain. (Okay, that’s not how demyelination is technically described, but you get the picture.) The thing is, the scientists have no idea why this happens, so they can’t stop it or prevent it.
People don’t always understand that living with MS means something different for every single person. It all depends on which specific nerve is being attacked.
Let’s say someone told you that they had a computer virus. You might say, “Oh, yeah, bummer – I had a computer virus and I couldn’t print,” but they might respond, “Print? I can print! The computer virus I have makes my web browser crash whenever I download something.” Someone else might say, “Man, when I got a computer virus, I got the Blue Screen of Death.” Obviously, it all depends on which part of the computer system gets attacked by the virus.
That’s how MS is. If the nerves to your eyes are being attacked, you are going to have very different symptoms than someone whose myelin is being destroyed on the nerves to their arms or legs or bladder. The human body has two kinds of nerves, too – sensory nerves, which affect what you feel, and motor nerves, which allow muscle movement – and depending on which type of nerve is being attacked, symptoms can be very different. In fact, no two people with MS are going to have the same course of the disease.
So what does MS mean for me? Continue reading “What is MS, anyway?”
