People with carotid stenosis should also work closely with their healthcare providers to control other risk factors for stroke. Depending on the blood levels and the person's other risk factors, medications to lower cholesterol may be given.

This is a type of reversible stroke that often goes away after a few minutes. These people can often get treatment that will prevent a stroke in the future. For instance, people may be advised to take aspirin or have carotid artery surgery to correct a blockage in a neck artery.
