What causes stroke?

Stroke is caused by a blockage of blood supply to, or a bleed within, the brain.

How to recognise stroke and transient ischemic attack

  • Many people are not aware of the symptoms of stroke or transient ischemic attack (TIA) and often do not go to hospital if either of these events happen.
  • Symptoms of stroke are sudden. Common ones include:
    • numbness or weakness of face, arm or leg – especially on one side of the body
    • vision problems
    • loss of coordination
    • confusion or trouble speaking or understanding
    • severe headache.
  • Symptoms of a TIA are similar to stroke, but last only minutes or hours. Only a doctor can tell the difference between a TIA and a stroke. Do not wait to see if it goes away. If someone has the symptoms, phone for emergency medical help immediately.

What to do if stroke happens

  • Stroke is a medical emergency. If someone has a stroke, phone for emergency medical assistance urgently.
  • Even though the symptoms of a TIA are short-lasting and may not seem severe, a TIA is a medical emergency. Seek medical assistance urgently. Do not wait to see if ‘it goes away’.

Why is stroke a major health issue?

  • There are over 13.7 million new strokes each year*. Globally, one in four people over age 25 will have a stroke in their lifetime.**
