Stroke: Causes, symptoms and prevention

What is a stroke?

A stroke is a life-threatening medical emergency that happens when the blood supply to part of the brain is cut off.



The blood supply may be cut off by a blood clot or from a burst blood vessel.



A person having a stroke may lose control over their movement, perception and speech. They may also lose consciousness.



Prompt hospital treatment is essential for stroke survival.
