What is a Stroke?
A stroke - also known as a cerebrovascular accident, is defined as the result of an acute deprivation of blood to part of the brain by the narrowing or thrombosis of an artery. This causes damage to, or death of, brain cells which are starved of oxygen. Alternatively it may be a result of physical damage to the brain caused by bleeding or a haemorrhage. Where the blood supply to part of the brain is interrupted for more than 24 hours - a stroke has occurred.
Stroke Symptoms
Strokes usually occur suddenly, and are unique to the individual, each one affecting a person in different ways, as different parts of the brain control different parts of the body. The main areas which may be affected are speaking, memory, swallowing and moving.

* numbness in the arms or legs
* loss of vision on one side
* weakness in the facial muscles & droop in the mouth
* slurred speech or speech difficult to understand

* difficulty swallowing
* loss of muscle coordination or balance
