There are more than 100,000 strokes in the UK each year, or around one every five minutes.
Around 40,000 people die each year from a stroke, making it the UK's fourth biggest killer.
It’s crucial that the signs of a stroke are caught quickly, as early treatment can mean the difference between recovery, disability or death.
Symptoms include numbness or weakness in the face, being unable to speak properly, loss of focus and difficulty moving limbs.
There are also less well-known symptoms such as dizziness, a very bad headache, difficulty swallowing and confusion.iPhone transfer software
Age is a risk factor – the average age for men to have a stroke is 72 and for women is 78.
A family history of stroke also makes you more susceptible, particularly if a parent suffered a stroke.
While you can’t reverse certain risk factors, there are lifestyle changes you can make to mitigate your chances of having a stroke.
Heavy drinkers are more likely to have strokes, but studies have shown that drinking a little alcohol can actually decrease your risk.
"Studies show that if you have about one drink per day, your risk may be lower," said Dr Natalia Rost, associate professor of neurology at Harvard Medical School.
