Prognosis of Strokes

Some strokes are minor and cause little or no permanent damage. Major strokes, however, can cause life-long disability. A severe stroke typically results in paralysis of one side of the body, possibly accompanied by difficulty speaking, loss of sight, or trouble with balance. Sometimes a severe stroke can cause a coma or death. The severity of a stroke and the eventual degree of recovery depends on a variety of factors including which areas of the brain are damaged, how much of the brain has been damaged, how quickly blood flow is restored to the damaged brain, and the age of the patient.
