Transient Ischemic Attack (TIA): A Serious Stroke Warning

A Transient Ischemic Attack (TIA) happens when blood flow to part of the brain is briefly blocked.
It causes stroke-like symptoms that resolve within minutes or hours.

Although symptoms disappear, a TIA is not harmless.

A TIA is a medical emergency and a strong warning sign of a future stroke.

Why a TIA Matters

  • Many full strokes occur within hours or days of a TIA
  • Early treatment can prevent permanent brain damage
  • Ignoring a TIA can lead to a major, disabling stroke

Think of a TIA as your brain’s early warning alarm.

TIA Symptoms: Use FAST

TIA symptoms are the same as stroke symptoms.

Remember FAST:

  • F — Face: drooping or numbness on one side
  • A — Arms: weakness or inability to raise both arms
  • S — Speech: slurred, confused, or strange speech
  • T — Time: call emergency services immediately

Other possible symptoms include:

  • Sudden vision problems
  • Sudden confusion or difficulty understanding speech
  • Sudden dizziness or loss of balance
  • Sudden severe headache with no known cause

If these symptoms occur — even briefly — seek emergency care.

If Symptoms Go Away, What Should You Do?

Even if symptoms completely resolve:

  • Call emergency services
  • Do not wait for a GP appointment
  • Do not assume it was “nothing”

Doctors can:

  • Identify the cause
  • Start medications to reduce stroke risk
  • Arrange further testing or procedures if needed

What Happens After a TIA?

Evaluation may include:

  • Brain imaging
  • Heart rhythm monitoring
  • Blood tests
  • Medication review

Treatment often focuses on preventing a future stroke, which may involve:

  • Blood pressure control
  • Blood thinners or antiplatelet medication
  • Cholesterol treatment
  • Lifestyle changes

Follow-up care is critical.

Can TIA Happen at Any Age?

Yes. TIA can occur in:

  • Older adults
  • Young adults
  • People without obvious risk factors

Any sudden neurological symptoms at any age should be treated as an emergency.

Bottom Line

A TIA is not a false alarm.

It is a chance to prevent a major stroke — but only if acted on immediately.

If you suspect a TIA, call emergency services right away.
