What is a stroke?

A stroke is caused by a disturbance of blood supply to the brain. Strokes are the leading cause of disability in the UK and the third most common cause of death after cancer and coronary heart disease.

 

There are two main types of stroke, ischaemic and haemorrhagic, which require different types of treatment.

 

A TIA (Transient ischaemic attack) or 'mini-stroke' is similar to a stroke and has the same signs, but gets better within 24 hours. However, it is important not to wait and see if the signs get better as it could be a full stroke. And, although TIA may not itself cause any serious illness, it could be a warning sign of a more serious stroke and requires the same F.A.S.T. action to call 999 for an ambulance.
