DEAR MAYO CLINIC: If you get to the hospital quickly after having a stroke and get treatment right away, does that mean there won’t be any of the typical after-effects of a stroke?
ANSWER: Although early treatment does not guarantee that there won’t be any lasting effects from a stroke, it can dramatically decrease the risk of permanent brain damage. If you have any symptoms of a stroke, get emergency medical care right away.
There are two types of stroke. The first, called an ischemic stroke, is due to a lack of blood supply to an area of the brain, caused by a blocked artery. This deprives brain tissue of oxygen. Within minutes, the brain cells begin to die. Ischemic strokes make up about 85 percent of all strokes.
