n A stroke is a brain attack: For your brain to function, it needs a constant blood supply, which provides vital nutrients and oxygen to the brain cells. A stroke happens when the blood supply to part of the brain is cut off and brain cells are damaged or die.
n A person may become numb, weak or paralysed on one side of the body. They may slur their speech and find it difficult to find words or understand speech. Some people lose their sight or have blurred vision, and others become confused or unsteady.
n Strokes affect people in different ways, depending on the part of the brain that is affected, how widespread the damage is and how healthy the person was before the stroke. But strokes can damage: bodily functions; thought processes; ability to learn; and how people communicate.
n About a third of people who have a stroke make a significant recovery within a month. But most stroke survivors will have long-term problems. It may take a year or longer for them to make the best possible recovery. In the most severe cases, strokes can be fatal or cause long-term disability.
n A stroke is always a medical emergency and symptoms should be acted upon fast:
FACIAL weakness: Can the person smile? Has their mouth or eye drooped?
ARM weakness: Can the person raise both arms?
SPEECH problems: Can the person speak clearly and understand what you say?
