Carotid artery stenosis, also called carotid artery disease, is a condition that can lead to stroke. As the condition advances, the most common first sign of carotid artery disease may be a transient ischemic attack (TIA), also called a mini-stroke. For some people, a stroke is the first sign of any problem.
A TIA occurs when there is low blood flow or a plaque briefly blocks an artery that supplies blood to the brain. the person at a higher risk of stroke. With a TIA, the person may have the same symptoms as he would have for a stroke. It usually lasts a few minutes to an hour. Symptoms go away entirely within 24 hours, with complete recovery.
Signs and symptoms of a stroke or TIA include:
*Numbness or loss of feeling in the face or in an arm or leg
*Difficulty speaking (called aphasia) and understanding
*Sudden loss of vision, blurred vision, or difficulty in seeing out of one or both eyes
*Sudden dizziness or loss of balance
*Sudden, severe headache with no known cause
The symptoms of a TIA and stroke are the same. A stroke is loss of blood flow (ischemia) to the brain that continues long enough to cause permanent brain damage.
