What causes the symptoms of multiple sclerosis?

ANSWER

A plaque in the brain or spinal cord changes the electrical signals that zip up and down nerves. They can get slower, distorted, or stop altogether. Those signal changes cause the symptoms of multiple sclerosis (MS). One example of an MS flare is optic neuritis, inflammation of the nerve that connects the eye and the brain, which makes it harder to see.
