What is a Stroke

A stroke is any interruption in blood flow to the brain. This includes blockages cause by clots in a blood vessel or when a vessel bursts and blood leaks into the brain tissue causing damage. Without quick restoration of proper blood flow brain cells may die and permanent damage may occur.

About 80% of strokes are ischemic, which means they are caused by the interruption of blood flow to the brain due to a blood clot. The buildup of plaque (fatty materials, calcium and scar tissue) is involved in most ischemic strokes – narrowing the arteries that supply blood to the brain, interfering with, or blocking the flow of blood. This “narrowing” is called atherosclerosis

What is TIA?

A TIA, or Transient Ischemic Attack – which is also known as a “mini-stroke” – is caused by a temporary interruption of blood flow to the brain. The symptoms (warning signs) are similar to an ischemic stroke except they go away within a few minutes or hours. Many people can have a TIA without even knowing it. A TIA is an important warning sign that puts you at increased risk of a full-blown stroke.
