What Happens During a Stroke?

Ischemic Strokes

Ischemic Strokes

Ischemic strokes are caused by blood clots, and are the most common type of stroke—about 87 percent of stroke victims have an ischemic stroke. Blood clots form as a result of atherosclerosis (hardening of the arteries). In atherosclerosis, fatty deposits and cholesterol called “plaque” line the artery walls. Plaque eventually gets large enough that it causes a blockage, cutting off vital blood flow to the brain.
