A stroke is a serious medical condition that occurs when the blood supply to the brain is disturbed.
Like all organs, our brain needs the oxygen and nutrients provided by our blood to function properly. If the supply of blood is restricted or stopped, brain cells begin to die. This can lead to brain damage and possibly death.
Strokes are a medical emergency, and prompt treatment is essential because the sooner a person receives treatment for a stroke, the less damage is likely to happen.
