When does a Stroke Occur?

A stroke is a life-threatening condition that occurs when the blood vessel that carries nutrients and oxygen to the brain is blocked by a clot or ruptures.

It is one of the leading causes of death as well as one of the main causes of disability in many countries around the world. A Stroke falls into three main types, depending on what caused it:
