What is multiple sclerosis? Dr. Oz uses an electrical cable to explain how the disease attacks a patient's central nervous system.
"Imagine that [the cable is] a nerve going down to your hand," he says. "They have cables around them—insulation that protects you so the electricity can go where it's supposed to go. … With multiple sclerosis, your immune system attacks that lining, that insulation, and it makes little cracks. As soon as that illness gets a little more aggressive, it actually takes whole chunks of that insulation away."
As the nerves become more exposed, Dr. Oz says patients experience electrical, firing pain throughout their bodies. "The nerves send back messages because they're not getting the right kind of input from the brain," he says.
