What is a Stroke?

A stroke is a brain injury caused when a blood vessel to the brain becomes blocked or bursts, cutting off blood flow and oxygen to the brain. When injury occurs to the brain, and part of the brain cannot get the  blood (and oxygen) it needs, the brain cells die. The symptoms of your stroke depend on where in the brain the cells are impacted.

Types

The two major kinds of stroke are:

  • Ischemic stroke is caused by a blood clot, which blocks an artery feeding the brain. When the blood supply is interrupted, that portion of the brain can no longer function.. About 80 percent of all strokes are ischemic. In many individuals, stroke is preceded by transient episodes of diminished blood supply. These transient ischemic attacks provide warning of impending stroke and create an opportunity to intervene before stroke occurs.
  • Hemorrhagic stroke results when a blood vessel bursts and leaks blood into the brain. A cerebral hemorrhage occurs when an artery in the brain ruptures, and blood under pressure forces itself into brain tissue. This creates a mass of blood that distorts nearby brain structures and interrupts brain function.
