A stroke occurs when flow of blood to the brain is stopped (usually due to blockage, haemorrhage or ischaemia). There are two types of strokes: haemorrhagic or ischaemic.

  • A haemorrhagic stroke occurs when there is a blood vessel in the brain that bursts due to weakness – this causes blood to leak into the brain, resulting in a stroke.
  • An ischaemic stroke occurs when arteries become blocked due to plaque (fat, cholesterol and other matter) build up.



Factors that increase the chance of having a stroke can include:



Symptoms of stroke can include:

  • Sudden and severe headache
  • Changes in hearing, vision and alertness
  • Memory loss
  • Numbness in body parts
  • Muscle weakness
  • Face may droop on one side
  • Slurred speech
  • Dizziness
  • Difficulty swallowing


  • Medication
  • Surgery
