A stroke is sometimes called a ‘brain attack’. It happens when a blood clot in an artery breaks and plugs up the flow of blood to an area of the brain. When this happens brain cells begin to die because of lack of oxygen. This takes only 3 minutes of lack of oxygen from arterial supply before the brain cells begin to die. This death of the cells will result in brain damage.

This brain damage is called a stroke. Many times the abilities that are lost include speech, memory or movement. How much damage is done and to what functions depends upon where the stroke happened in the brain and how much of it was damaged.
