Understanding the severity of stroke
What is a stroke?
Stroke is a disease that affects the arteries leading to and within the brain. It is the No. 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.
