Multiple sclerosis (MS) is progressive degeneration and demyelination of neurons of the brain, spinal cord, and cranial nerves, especially the optic nerve. The loss of myelin ultimately leads to scarring or sclerosis and plaque formation, which interferes with the transmission of nerve impulses (similar to an electrical wire stripped of its insulation).
