A transient ischaemic attack (TIA), sometimes called a 'mini-stroke', happens when the blood supply to part of the brain is temporarily interrupted, causing stroke-like symptoms that resolve within 24 hours, often much sooner. Despite resolving, a TIA is a serious warning sign of stroke risk.

01 · Know
What is Transient ischaemic attack (TIA)?
A transient ischaemic attack (TIA), sometimes called a 'mini-stroke', happens when the blood supply to part of the brain is temporarily interrupted, causing stroke-like symptoms that resolve within 24 hours, often much sooner. Despite resolving, a TIA is a serious warning sign of stroke risk.
Symptoms are the same as those of a stroke, including facial drooping, arm weakness, and speech difficulty, but they go away on their own. A TIA needs the same emergency response as a stroke, since it can't be distinguished from one at the time it's happening.
02 · Understand
Clinical context
This is a medical emergency, even after symptoms pass
Anyone with symptoms of a TIA needs emergency assessment and urgent follow-up, since the short-term risk of a full stroke is significantly increased.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Treat any stroke-like symptoms as an emergency.Call emergency services immediately, even if symptoms resolve quickly, since a TIA cannot be told apart from a stroke as it's happening.
- 2Seek urgent medical assessment even after symptoms pass.A TIA significantly increases the short-term risk of a full stroke, so urgent investigation and preventive treatment are essential.
- 3Take any prescribed preventive medication.Blood-thinning or cholesterol-lowering medication may be prescribed to reduce future stroke risk.
- 4Address risk factors.Managing blood pressure, cholesterol, diabetes, and smoking all help reduce the risk of a future stroke.
- 5Attend all follow-up appointments and tests.These help identify the cause of the TIA and guide ongoing preventive treatment.

BarnMD Bottom Line
A TIA is a serious warning sign and a medical emergency, even though symptoms resolve on their own — it significantly raises the risk of a full stroke soon after.
Never wait to see if TIA symptoms come back — call emergency services immediately, exactly as you would for a stroke.
