Carotid Artery Disease: Symptoms & Signs

Carotid artery disease refers to atherosclerosis, or plaque buildup, in the carotid arteries. The carotid arteries are in the neck and carry oxygen to the face, neck, brain, and head. Carotid artery disease itself can cause transient ischemic attack (mini-stroke) or stroke if oxygen supply is reduced to the brain.

Carotid artery disease may not produce signs and symptoms until it causes damage such as stroke. Then, symptoms and signs can include those of a stroke such as

  • weakness on one side of the body,
  • temporary or permanent vision loss in one eye,
  • speech problems, or
  • an inability to move facial muscles on one side.
