About stroke

A stroke happens when someone has a bleed or a blood clot in their brain, which damages their brain tissue and usually produces physical signs of disability.

A blood clot in the brain can be caused by atherosclerosis (narrowing of the arteries) or atrial fibrillation. Bleeding can sometimes be caused by high blood pressure.

Some people develop symptoms similar to a stroke, but fully recover within a few hours. This may be a transient ischaemic attack (TIA), also called a mini stroke.

Important

A stroke is a medical emergency. If you think you or someone else is suffering from stroke symptoms, call 111 for an ambulance immediately.
