Brain death is the irreversible end of all brain activity (including involuntary activity necessary to sustain life) due to total necrosis of the cerebral neurons following loss of brain oxygenation. It should not be confused with a persistent vegetative state. Patients classified as brain dead can have their organs surgically removed for organ donation.
Brain death, either of the whole brain or the brain stem, is used as a legal indicator of death in many jurisdictions.

Famous quotes containing the words brain and/or death:
“Public morning diversions were the last dissipating habit she obtained; but when that was accomplished, her time was squandered away, the power of reflection was lost, [and] her ideas were all centered in dress, drums, routs, operas, masquerades, and every kind of public diversion. Visionary schemes of pleasure were continually present to her imagination, and her brain was whirled about by such a dizziness that she might properly be said to labor under the distemper called the vertigo.”
—Sarah Fielding (1710–1768)
“Now they heap the funeral pyre,
And the torch of death they light;
Ah! ‘tis hard to die by fire!”
—William Makepeace Thackeray (1811–1863)
