For every minute that brain cells are deprived of oxygen and die during the stroke, brain damage increases and injures more of the brain. Furthermore, the damage does not stop there. Research has found that brain cells in the area of the stroke aren't the only ones in danger. Through a process called secondary injury, dying brain cells set off a chain reaction of electrical and chemical events that can endanger and kill brain cells in a much larger surrounding area. The larger the number of brain cells killed, the more extensive the injuries and disabilities the patient will suffer.
Stroke is the third leading cause of death in the U.S., and the top cause of permanent disabilities.
Nearly a third of all strokes are fatal, and another third cause long term physical challenges. Heart attack is caused by a lack of blood flow to the heart, and stroke is caused by a lack of blood flow to the brain. If you have heart disease, work with your physician to keep it under control. Only drink in moderation. Keep cholesterol under control.
