STROKE: ARE YOU AT RISK? WHAT YOU SHOULD KNOW


Strokes occur due to problems with the blood supply to the brain: either the blood supply is blocked or a blood vessel within the brain ruptures, causing brain tissue to die. A stroke is a medical emergency, and treatment must be sought as quickly as possible!

There are three main kinds of stroke:

1. Ischemic strokes (caused by blockage or narrowing of arteries supplying blood to the brain)

2. Hemorrhagic strokes (caused by rupturing or bleeding of arteries in the brain)

3. Transient ischemic attacks (TIAs), also referred to as mini-strokes (caused by temporal interruption of blood flow to the brain)

People at risk for stroke include
1. those who have high blood pressure,
2. high cholesterol,
3. diabetes,
4. and those who smoke.
5. People with heart rhythm disturbances, especially atrial
fibrillation are also at risk.
