What is a Stroke?

What is a Stroke?

A stroke can occur when the blood supply to an area of the brain is reduced or blocked, causing the brain to be starved of oxygen. It is essentially the same process as that which affects the heart in a heart attack. Strokes can also be caused by a haemorrhage in the brain. People who have strokes are affected in different ways, ranging from complete recovery to the chance of permanent disability and sometimes death. The effects of stroke depend on which part of the brain has been damaged. Recovery can continue to occur for several years after the stroke.
