Stroke “stenosis” is typically caused by atherosclerosis, a condition in which the inside wall of a blood vessel supplying blood to the brain becomes narrowed due to the accumulation of fatty deposits, known as plaques, on the inside wall of the vessel. High blood pressure and high cholesterol are both risk factors for this form of stenosis, as is smoking.
