Brain attack
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.
Infarction
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.
