A stroke is said to take place when blood flow to a part of the brain stops. A stroke is sometimes called a "brain attack." A stroke is a state of medical emergency. It happens when blood flow to a part of the brain stops. And then, within minutes, brain cells begin to die. A stroke is a brain attack which is more like a heart attack. Just like a heart attack, stroke is also a medical emergency.If blood flow is stopped for more than a few seconds, the brain cannot get blood and oxygen. The brain cell dies and causes a permanent damage. A stroke may occur when there is clot in the artery. Due to this, blood cannot reach the brain.

What are the causes of stroke?
A hemorrhagic stroke occurs when a blood vessel in part of the brain becomes weak and therefore, bursts open, which causes blood to leak into the brain. Some people have defects in the blood vessels of the brain that make this easier to happen.
