If someone is brain dead and their organs are donated, they are a cadaveric donor. The most common causes of brain death are accidents, strokes, and cerebral hemorrhages (bleeding in the brain). Donors are screened for any health conditions that would prevent transplantation of their organs.
A brain dead person is legally dead and will never recover, even though their heart may continue to beat for a short time. If the personís family decides to donate, the body is kept on a ventilator to provide oxygen to the organs and tissues until they can be surgically removed. Once removed, a kidney can be transplanted up to 36 hours later. The donation is anonymous: you wonít know who your donor was, and the donorís family wonít know who you are (unless you both agree otherwise).
