Brain cells continue to die, and physical and mental functions continue to decline. It is not unusual for there to be a second stroke or a heart attack during this period. It can be weeks before improvement begins. In about one-third of all strokes there is good recovery with no lasting damage. In another third there is permanent disability.
Many strokes are fatal.
You can best prevent a stroke by keeping risk factors under control. Have your blood pressure checked regularly and seek treatment if it is high. Eat a low-fat diet and follow an exercise program. If you are at high risk, your physician may have you take low-dose aspirin daily to prevent blood clots. Cigarette smoking is another important factor that can lead to strokes.
