Carotid artery supplies blood to brain. The greatest danger of carotid artery disease is carotid arteries blocking, which hamper the blood supply to brain and increases the risk of stroke. In the early stage, carotid artery disease has no symptom or sign. When the disease is serious enough that brain blood supply is affected, patients may have weakness, numbness or paralysis in arm or leg on one side. Patients also have slurred speech or difficulty understanding other people's words. They may also have sudden unilateral eye blindness. Hypertension is an important risk factor that leads to carotid artery disease. Treatment of carotid artery disease includes changing lifestyle, medication, surgery or stent implantation.
