About Stroke

Stroke is the number 5 cause of death and the leading cause of adult disability in the United States.

What is Stroke?
Stroke is a disease that affects the arteries leading to and within the brain. It is theNo. 5 cause of death and a leading cause of disability in the United States. 

A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens
, part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die.

What are the types of stroke?
Stroke can be caused either by a clot obstructing the flow of blood to the brain (called an ischemic stroke) or by a blood vessel rupturing and preventing blood flow to the brain (called a hemorrhagic stroke). A TIA (transient ischemic attack), or "mini stroke", is caused by a temporary clot. 
What are the effects of stroke?
The brain is an extremely complex organ that controls various body functions.  If a stroke occurs and blood flow can't reach the region that controls a particular body function, that part of the body won't work as it should.
