What is TIA?
A transient ischaemic attack (TIA) is often called a ‘mini-stroke’ or’ warning stroke.’
The symptoms are similar to those of a full-blown stroke, but they do not last as long – anything from a few minutes up to 24 hours. As with a stroke, the symptoms mean that a part of the brain is not getting enough blood and oxygen. A TIA should never be ignored. Without treatment, about one in four people who have had a TIA will go on to have a full blown stroke within a few years. (Stroke Association factsheet on TIA). The risk of a full blown stroke after a TIA is greatest in the first few days and so all patients with TIA symptoms should seek urgent medical attention.
