Model helps explain why some patients with multiple sclerosis have seizures

Why does multiple sclerosis sometimes cause seizures?

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system that affects nearly 2.3 million people worldwide. MS is triggered when the immune system attacks the protective covering around nerve fibers, called the myelin sheath. The “demyelination” that follows damages nerve cells and causes impaired exchange of information between the brain and body as well as within the brain itself.

As the protective sheath — best imagined as the insulating material around an electrical wire — wears off, nerve signals slow down or stop. The result is impairment to a patient’s vision, sensation, and use of limbs depending where the damage takes place. Permanent paralysis occurs when nerve fibers are destroyed by the disease.
