Stroke Overview

A stroke happens when the blood supply to the brain is interrupted. Blood is carried to the brain by blood vessels called arteries. Blood contains oxygen and important nutrients for your brain cells. Blood may be interrupted or stop moving through an artery, because the artery is blocked (ischaemic stroke) or bursts (haemorrhagic stroke). When brain cells do not get enough oxygen or nutrients, they die.

Risk factors include high blood pressure, high cholesterol, smoking and atrial fibrillation (irregular heartbeat).

  • Every 10 minutes an Australian has a stroke
  • Over 400,000 Australians have an irregular heartbeat
