What is a TIA?

A Transient Ischaemic Attack (TIA) is sometimes termed a minor stroke or “mini” stroke. When the signs of stroke are present but go away within 24 hours, the term TIA is used. The causes and symptoms of a transient ischaemic attack (TIA) are similar to those of a stroke.

TIA episodes usually last only a few minutes but may last for several hours. They generally disappear quickly and unfortunately, are often ignored. Just like a stroke, a TIA will require emergency treatment. About 1 in 5 people who have a TIA will have a major stroke within the next three months and a large part of the risk occurs in the first few days.  Therefore, TIA should never be ignored.

TIA’s should be regarded as a warning sign that the person is at risk of a stroke and should be investigated promptly.

It is important that if stroke symptoms occur (see Signs of stroke) the person sees a doctor promptly, even if the signs go away and you feel completely better. The doctor will try to find the underlying cause of the TIA and then organise treatment to lower your risk of another TIA or stroke.

If you have experienced a TIA or a stroke, it is important that you prevent another stroke.
