What is Stroke?

Stroke is a "brain attack", which occurs when the blood supply to the brain is interrupted. This type of stroke caused by the blockage of blood vessel in the brain or neck is called an ischemic stroke and is the most frequent cause of stroke.

A stroke is an emergency!

Stroke is a medical emergency in which every minute counts. The longer the blood flow is cut off to the brain, the greater the damage.

Stroke injures the brain. A bystander may not realize that someone is suffering from a stroke attack. Stroke victims have the best chance of recovery if someone recognizes the signs and acts quickly.

First Aid: If you suspect a person has had a stroke, use the FAST (Face-Arm-Speech-Test) guide:

F Facial weakness: the person is unable to smile and their eye and/or mouth is droopy
A Arm weakness: the person is only able to raise one arm
S Speech problems: the person is unable to speak clearly or cannot understand the spoken word
T Time is of the essence: call medical emergency help if you suspect the person has had a stroke
