A stroke happens when the blood supply to your brain is cut off. If your brain doesn't get enough blood to provide the oxygen and nutrients it needs, your brain cells will become damaged or die.
Every year in the UK, around 150,000 people have a stroke. It's the third most common cause of death in the UK, and also the leading cause of severe disability .
Most people who have a stroke are over 65, but many are younger than this. Anyone can have a stroke, including babies and children.
A stroke is a medical emergency, so recognising the symptoms quickly and getting treatment in hospital as soon as possible is very important.
