What is a TIA (Transient Ischaemic Attack)
TIA is a medical emergency
TIA stands for Transient Ischaemic Attack. A TIA is caused by a temporary blockage in the blood vessels in the brain. If someone has a TIA they usually recover within 24 hours so it is often called a mini-stroke or a warning stroke.
What is the difference between a TIA and an Ischaemic Stroke?
The difference between a TIA and an Ischaemic stroke is that the effects of a TIA are only temporary (transient). A small blood clot (thrombus or embolus) may cause a blockage in the blood vessel in the brain. Unlike a ischaemic stroke, the clot may break up quickly allowing the blood to flow through the blood vessel again.
What are the symptoms of a TIA?
If you have a TIA (mini-stroke) you will have the same types of feelings as if you were having a stroke, for example:
You may experience sudden;
Unlike a stroke, these symptoms only last for a short time - commonly between 30 - 60 minutes, but may last up to 24 hours. Unlike with a stroke, the effects of a TIA don't cause permanent damage.
However, a TIA (mini-stroke) can act as a ‘warning’ that you could have a more damaging stroke in the future and you should take it seriously.
Is there a risk of Stroke after a TIA
The risk of stroke is greater for people who have had a TIA. The most important issue is to reduce the risk of having a stroke.
It is important to report any strange feelings or sensations to your doctor immediately. Your doctor can do tests to determine whether you have had a TIA and if so, give you treatment to try to lower your chances of having another TIA (mini-stroke) or an even a bigger stroke.
