What is Stroke ?
A stroke or “brain attack” occurs when a blood clot blocks an artery (a blood vessel that carries blood from the heart to the body) or a blood vessel (a tube through which the blood moves through the body) breaks, interrupting blood flow to an area of the brain. When either of these things happen, brain cells begin to die and brain damage occurs.
When brain cells die during a stroke, abilities controlled by that area of the brain are lost. These abilities include speech, movement and memory. How a stroke patient is affected depends on where the stroke occurs in the brain and how much the brain is damaged.
For example, someone who has a small stroke may experience only minor problems such as weakness of an arm or leg. People who have larger strokes may be paralyzed on one side or lose their ability to speak. Some people recover completely from strokes, but more than 2/3 of survivors will have some type of disability.
Types of Stroke
There are two major kinds of stroke. The first, called an ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel or artery in the brain. About 80 percent of all strokes are ischemic. The second, known as a hemorrhagic stroke, is caused by a blood vessel in the brain that breaks and bleeds into the brain. About 20 percent of strokes are hemorrhagic.
Stroke Symptons
If you have any stroke symptoms, seek immediate medical attention.
Stroke Symptoms include:
SUDDEN numbness or weakness of face, arm or leg – especially on one side of the body.
SUDDEN confusion, trouble speaking or understanding.
SUDDEN trouble seeing in one or both eyes.
SUDDEN trouble walking, dizziness, loss of balance or coordination.
SUDDEN severe headache with no known cause.
If you think someone may be having a stroke, act F.A.S.T. and do this simple test:
Know the Symptoms & Act F.A.S.T.
Face
Is the face dropping on one side?
Arm
Is one arm weaker than the other?
Speech
Is the person able to speak? Are words jumbled or slurred?
Time
To act quickly and seek medical help!
FACE
Ask the person to smile. Does one side of the face droop?
ARMS
Ask the person to raise both arms. Does one arm drift downward?
SPEECH
Ask the person to repeat a simple sentence. Are the words slurred? Can he/she repeat the sentence correctly?
TIME
If the person shows any of these symptoms, time is important.
What should a bystander do?
If you believe someone is having a stroke- if he or she suddenly loses the ability to speak, or move an arm or leg on one side, or experiences facial paralysis on one side- please consult doctor.
Act in Time.
Stroke is a medical emergency. Every minute counts when someone is having stroke. The longer blood flow is cut off to the brain, the greater the damage. Immediate treatment can save people’s lives and enhance their chance their chances for successful recovery.
