Understanding and Preventing Stroke: Key Risk Factors & Actions

According to the National Stroke Association, stroke is the number three cause of death in the United States. Strokes happen when a clot blocks a blood vessel and interrupts the flow of blood to a portion of the brain. Functions controlled by that area are lost with the cells die. The effects of a stroke depend on the location and amount of damage to the brain cells, and 80 percent of strokes are preventable.
