What causes an ischemic stroke?

Ischemic strokes usually result when a blood clot or accumulation of fat in an artery (atherosclerosis) causes a reduction in blood flow in the brain. Occasionally, lipohyalinosis, a disorder in which fat and tissue build up in the arteries, leads to an ischemic stroke. Other causes of ischemic strokes include vasculitis (blood vessel inflammation), infections, substance abuse, and extremely low blood pressure.
