It is estimated that nearly 800,000 people have a stroke each year, according to the Centers of Disease Control and Prevention (CDC). A stroke occurs when there is a blockage of oxygen to the brain. They can occur at any age, but the risks increase as you get older.
There are two main types of stroke: Ischemic and Hemorrhagic.
About 87% of strokes are Ischemic strokes. These occur when a blood clot prevents blood from flowing to parts of the brain. Blood clots can form in two different ways.
First, a clot can form due to a buildup of plaque in the arteries. The plaque forms from fat, cholesterol and other inhibitors, and causes the blood vessels to narrow, affecting blood flow.
Second, a clot can form after a break in another blood vessel in the body. It can travel throughout the body and get caught in the much smaller vessels in the brain.
A transient ischemic attack (TIA) is often referred to as a “mini stroke” and is caused by a temporary blockage, and can be a warning to a potential, future stroke.
Hemorrhagic strokes happen when blood vessels in the brain are weakened and rupture. The pressure builds on the surrounding tissue, cutting off blood supply and causes damage to the brain. Blood vessels can be weakened by an aneurysm or chronically high blood pressure.
Stroke is potentially very serious, but there are preventative measures to take that can help lower the risk of stroke. Learn how the services at Kingston can help you stay proactive with your health.
