What is a stroke?
A stroke occurs when the blood supply to the brain is interrupted causing brain damage and its associated signs.
This is usually caused by a blockage of a brain blood vessel or bleeding when a brain blood vessel bursts. Blood carries oxygen and nutrients to the brain and this is essential for its normal function. When the blood supply is cut off, brain cells die and this causes the signs of stroke.
What are the signs of stroke?
The most common signs of a stroke are sudden drooping of one side of the face, weakness of one side of the body and difficulty speaking or understanding speech.
A stroke may also cause numbness on one side of the body, loss of balance or incoordination, double vision, difficulty seeing with one or both eyes and severe headache.
The mnemonic F.A.S.T. can help you remember how to recognise the important signs of a stroke. Learn about F.A.S.T. here.
FACE – Is it drooping on one side?
ARMS – Can they lift both arms and keep them there?
SPEECH – Does it sound strange or unclear?
TIME – Call 995 immediately if you spot any of those signs.
