Some people are confused about what exactly a stroke is.  A stroke, as defined by the World Health Organization, or WHO, is, “a neurological deficit of cerebrovascular cause that persists beyond 24 hours or is interrupted by death within 24 hours.”  In other words, a stroke is when you rapidly lose brain function due to lack of blood supply to the brain. 

The area of the brain that is unable to function causes you to lose the inability to move one or more limbs, makes you unable to understand or formulate speech, or you may lose vision.  Stokes may cause permanent neurological damage, complications, and death.  In the U.S. and Europe, strokes are the leading cause of adult disability.  Worldwide, strokes are the second most common cause of death.
