What Is A Plaque?

These spots of inflammation and scarring responsible for the hardening are often called plaques and are found in the white matter of the brain and spinal cord. They are called plaques because they looked like little plates to Charcot, the French doctor who first found them more than a century ago. Plaque is the French word for plate. They may also occur in the optic nerve, which is actually part of the brain and not really a “nerve.”
