What is a stroke?
Stroke is a type of cardiovascular disease. It affects the arteries
leading to and within the brain. A stroke occurs when a blood vessel
that carries oxygen and nutrients to the brain is either blocked by a
clot or bursts. When that happens, part of the brain cannot get the
blood (and oxygen) it needs, so it starts to die.
Clots that block an artery cause ischemic strokes. This is the
most common type of stroke. Ischemic strokes account for about
80.8% of all strokes.
Ruptured blood vessels cause hemorrhagic or bleeding strokes.
When part of the brain dies from lack of blood flow, the part of
the body it controls is affected. Strokes can cause paralysis,
affect language and vision, and cause other problems.
Transient Ischemic Attacks (TIA) are also referred to as "mini
strokes." They usually last just a few minutes and cause no
