Carotid Artery Disease
Carotid artery disease occurs when the major blood vessels in your neck (carotid arteries) become narrowed or blocked by fatty deposits called plaque. These arteries supply blood to your brain, and when they become blocked, it can lead to stroke. Carotid artery disease is responsible for about 10-15% of all strokes.
How common is Carotid Artery Disease?
When to seek help?
Many people with carotid artery disease have no symptoms at all. This is called asymptomatic carotid disease. However, some people experience warning signs that require immediate medical attention:
-
Sudden weakness or numbness in your face, arm, or leg (especially on one side)
-
Difficulty speaking or understanding speech
-
Sudden vision problems in one or both eyes
-
Dizziness or loss of balance
-
Sudden severe headache
These symptoms may indicate a transient ischemic attack ("mini-stroke") or stroke. Call 911 immediately if you experience any of these symptoms.
Should you be screened?
-
Routine screening for carotid artery disease is not recommended for people without symptoms. The US Preventive Services Task Force recommends against screening the general adult population because the potential harms may outweigh the benefits.
-
However, screening may be considered for certain high-risk individuals, such as those aged 55 or older. Talk to your doctor about whether screening is right for you based on your individual risk factors.
