Facts About Stroke
For the human brain to function at peak levels, blood must flow through its many vessels. If blood flow is obstructed to any part, the brain loses its energy supply and becomes injured. If blood is obstructed for more than several minutes, the brain cells' injury becomes permanent and tissue dies in the affected region. The loss or alteration of bodily function that results from an insufficient supply of blood to part of the brain is called a stroke.
