A stroke is a brain attack
A stroke is what happens when the blood supply to part of the brain is cut off. Blood carries essential nutrients and oxygen to the brain. Without a blood supply, brain cells can be damaged or destroyed and won.t be able to do their job.
Because the brain controls everything the body does, damage to the brain will affect body functions. For example, if a stroke damages the part of the brain that controls how limbs move, limb movement will be affected. The brain also controls how we think, learn, feel and communicate. A stroke can also affect these mental processes. A stroke is sudden and the effects on the body are immediate.
Stroke can cause brain tissue to die, and this is called cerebral infarction. An infarct is an area of dead tissue. It can be tiny or affect a larger part of the brain.
Common symptoms of a stroke
The first signs that someone has had a stroke are very sudden. Symptoms include: numbness, weakness or paralysis on one side of the body (signs of this may be a drooping arm, leg or lower eyelid, or a dribbling mouth); slurred speech or difficulty finding words or understanding speech; sudden blurred vision or loss of sight; confusion or unsteadiness; and a severe headache.
A stroke is a medical emergency.
If you see the signs of a stroke, act FAST and call 999. The sooner someone receives treatment, the better their chance of recovery.
