How to recognise the signs and symptoms of a stroke

A stroke is an illness that affects the blood vessels leading to and within the brain.

A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. When that happens, some part of the brain cannot get the blood and oxygen it needs, which causes the brain cells die.

Netcare 911 described the signs and symptoms of a stroke:

• Facial drooping: Ask a person to smile. Is one side of his or her face drooping downward? That may be the sign of stroke.

• Arms: Next, ask the person to raise both arms and note whether one drifts downwards.

• Slurred or strange speech: Finally, ask the person to repeat a simple sentence. Is it correct? Is it difficult to understand what the person is saying?

• Time: If someone shows these symptoms, call the emergency service on 10177 or 082 911 immediately.

Do not put off seeking medical attention, even if the symptoms disappear.
