Carotid Artery Disease
What is carotid artery disease?
Carotid artery disease is a condition affecting the major blood vessel that supplies oxygen-rich blood to your head and brain.
Like other vascular diseases, like atherosclerosis and peripheral arterial disease, carotid artery disease develops when sticky fat deposits called plaque start to collect in your arteries. These can lead to blockages that cause a stroke, a potentially life-threatening condition that strikes when your brain isn’t receiving oxygen because of a lack of blood.
Stroke is the leading cause of death in the United States, as well as the most common cause of permanent disability.
Commonly asked questions about carotid artery disease:
Carotid artery disease doesn’t typically cause any symptoms. So it’s possible to have the condition and not know it until you have a stroke or a transient ischemic attack (TIA).
A TIA is sometimes called a mini-stroke because it causes a temporary problem with blood flow to the brain that mimics the symptoms of a stroke but to a lesser degree. Having a TIA is a clear warning sign that you have a high risk of stroke.
Symptoms of stroke and TIA include a sudden loss of feeling or weakness in your face and arm on one side of your body. You might have trouble talking, or not understand what someone’s saying to you.
Your vision might dim, and you could feel dizzy and off-balance. You might also have a severe headache that arrives suddenly without reason.
If you or someone you’re with shows signs of a stroke or TIA, get medical help right away.
