According to the American Stroke Association, stroke is the fifth leading cause of death and disability in the United States. But, what is a stroke, and what are the types of strokes that can occur?
The purpose of the blood vessel is to carry oxygen and nutrients to the brain. A stroke occurs if the blood vessel is blocked by a clot or bursts, according to the American Stroke Association. When a stroke occurs, the brain cannot get the blood and oxygen the brain needs. As a reaction to this, the brain cells die.
There are three different types of stroke: ischemic stroke, hemorrhagic stroke, and transient ischemic attack (TIA).
Ischemic stroke accounts for 87% of all strokes. Ischemic stroke occurs when a blood vessel that is supplying blood and oxygen to the brain is blocked. According to the American Stroke Association, fatty deposits that line the vessel walls of the blood vessel are the main cause of ischemic stroke.
Hemorrhagic stroke occurs when a weakened blood vessel ruptures and bleeds to the surrounding tissue. This blood compresses the brain tissue, according to the American Stroke Association. There are two types of weakened blood vessels that can cause hemorrhagic stroke: aneurysms and arteriovenous malformations (AVMs)
A transient ischemic attack is a temporary blood blockage to the brain. A TIA is a warning for a full-fledged stroke. The American Stroke Association states 1/3 of people who have a TIA will have a more severe stroke within one year.
If you believe you or a loved one is experiencing a stroke, seek medical attention as soon as possible. To reduce your risk for stroke, consult your doctor on healthier ways to reduce your risk for stroke.
