Transient ischaemic attack (TIA)

Also called TIA or Mini-stroke

A transient ischaemic attack (TIA), or mini-stroke, is caused by a brief disruption in the blood supply to part of the brain. Symptoms are the same as a stroke, such as face drooping, arm weakness and speech problems, but they go away within 24 hours, often within minutes. A TIA is a warning that you are at higher risk of having a stroke soon.

What it is

Anyone who may have had a TIA should be assessed urgently, ideally within 24 hours.

Treatment aims to prevent a stroke and may include medicines to prevent clots and lower blood pressure and cholesterol, and sometimes surgery on a narrowed neck artery.

Common signs

  • Face drooping on one side
  • Weakness or numbness in one arm or leg
  • Slurred speech or difficulty understanding
  • Sudden loss of vision or double vision
  • Sudden dizziness or loss of balance

How it is usually diagnosed

  • Urgent assessment by a specialist
  • Brain scan
  • ECG and blood tests
  • Ultrasound of the neck arteries

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • TIA clinic letters
  • Brain and neck scan reports
  • ECG results
  • Medicine lists
  • Blood pressure and cholesterol results

Questions to ask your doctor

  • What caused the TIA?
  • Which medicines do I need to prevent a stroke?
  • Can I drive?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Any signs of a stroke, even if they go away: call 112 immediately
