What is Carotid Artery Disease

Carotid Artery Disease is the narrowing or blockage (stenosis) of the carotid arteries, most commonly caused by atherosclerosis (hardening of the arteries). The carotid arteries are two large blood vessels, one at each side of the neck, that supply oxygenated blood and nutrients to the front part of the brain, where thinking, speech, personality, sensory and motor functions reside.
