A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off.
Like all organs, the brain needs the oxygen and nutrients provided by blood to function properly. If the supply of blood is restricted or stopped, brain cells begin to die. This can lead to brain damage and possibly death.
Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke, the less damage is likely to happen.
The NHS Stroke Act FAST pages offer a great deal of information about stroke, including how to recognise the signs, some real stories of stroke sufferers and advice on how to live your life after a stroke.
As TIAs are serious, it is important that they are always investigated so that appropriate treatment can be given quickly. With treatment, the risk of a further TIA or a full stroke can be greatly reduced.
