Carotid Atherosclerosis

Carotid artery disease occurs when fatty deposits or plaques (atherosclerosis) block the blood vessels that transports oxygen-rich blood from the heart to the brain and carotid arteries in the head. The clogging increases the chances of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or effectively reduced.
Stroke deprives the brain of oxygen. Within a fraction of minutes, brain cells begin to die. Stroke is the most common cause of death. 
Carotid artery disease develops slowly. The first sign of this disease is a stroke or transient ischemic attack. A TIA is a temporary reduced blood flow to the brain.
Treatment of carotid artery disease usually involves a combination of lifestyle changes, medications and sometimes surgery. Treatment aims to reduce the chances of stroke by controlling or removing plaque buildup and preventing blood clots.
