carotid artery stenosis

Carotid artery stenosis is a narrowing of the carotid arteries, which are major blood vessels in the neck that supply blood to the brain. This narrowing is usually caused by a buildup of plaque—made up of fats, cholesterol, and other substances—within the artery walls. When the arteries narrow, blood flow to the brain can be reduced, increasing the risk of stroke. Symptoms may include sudden weakness, difficulty speaking, or loss of coordination. Diagnosis often involves imaging tests, and treatment options range from lifestyle changes and medications to surgery, depending on the severity of the condition.
