What is a stroke?
A stroke happens when the blood supply to part of the brain is cut off, killing brain cells. Damage to the brain can affect how the body works. It can also change how you think and feel. The effects of a stroke depend on where it takes place in the brain, and how big the damaged area is.
Different types of stroke
There are three different types of stroke:
An ischaemic stroke is caused by a blockage cutting off the blood supply to the brain. This is the most common type of stroke.
A haemorrhagic stroke is caused by bleeding in or around the brain.
A transient ischaemic attack or TIA is also known as a mini-stroke. It is the same as a stroke, except that the symptoms only last for a short amount of time. This is because the blockage that stops the blood getting to your brain is temporary.
What causes stroke?
As we age, our arteries become harder and narrower and more likely to become blocked. However, certain medical conditions and lifestyle factors can speed up this process and increase your risk of having a stroke.
Can you recover from stroke?
All strokes are different. For some people the effects may be relatively minor and may not last long. Others may be left with more serious problems that make them dependent on other people.
Unfortunately, some strokes can be very serious and some may lead to coma or sudden death. That's why it's so important to be able to recognise the symptoms and get medical help as quickly as possible.
The quicker you receive treatment, the better your chances for a good recovery.
Make sure you know how to recognise the symptoms of stroke.
