What is a stroke?
A stroke is a serious life-threatening medical condition that happens when the blood supply to part of the brain is cut off, explained the NHS.
The health site said: “Like all organs, the brain needs oxygen and nutrients provided by blood to function properly.
“If the supply of blood is restricted or stopped, brain cells begin to die and this can lead to brain injury, disability and possibly death.
“Strokes are a medical emergency and urgent treatment is essential.”
