A transient ischaemic attack, often called a TIA, is a temporary stroke-like event caused by a brief interruption of blood flow to part of the brain. Even if the signs go away, it still needs urgent medical assessment.
What is a transient ischaemic attack?
A TIA can cause the same kinds of warning signs as a Stroke, but the symptoms usually settle within a short time.
Because the signs can disappear, people sometimes call it a mini stroke. That wording is common, but it can be misleading if it makes the event seem harmless. A TIA can be a warning sign of a future stroke.
What signs might you notice?
Possible signs include:
- facial drooping
- weakness or numbness in one arm or one side
- slurred speech
- trouble understanding speech
- sudden confusion
- vision changes
- balance problems
You can still use FAST to look for common stroke-style signs.
Is a TIA an emergency?
Yes. Even if the person seems better after a short time, they still need urgent medical attention.
That is because a TIA can be an early warning sign that a full stroke may happen later.
What should you do in first aid?
- Treat it seriously.
- Call
000or seek urgent medical help straight away. - Note when the signs started and when they changed, if you can.
- Keep the person safe and calm.
- Watch breathing and responsiveness.
If the person becomes Unresponsive and is not breathing normally, start CPR.
Is a TIA the same as a stroke?
No. A TIA is temporary, while a stroke causes more lasting interruption or damage. But the practical first aid point is similar: both need urgent action.
That is why this page supports the broader Stroke page rather than replacing it.
Why does FAST still matter?
FAST is helpful because the first few signs may look exactly like a stroke at the time.
If you see facial drooping, arm weakness, or speech problems, the safest approach is to act quickly and get urgent help.
Quick answer
A transient ischaemic attack, or TIA, is a temporary stroke-like event caused by a brief interruption of blood flow to the brain. Even if the signs pass, it still needs urgent medical assessment because it can be a warning sign of future stroke.
