How brain death occurs?

[Yver]

Brain stem death is when a person no longer has any brain stem functions and has permanently lost the potential for consciousness and the capacity to breathe. Can anyone tell me how brain death occurs? Thank You!!

@yver Brain death can occur when the blood and/or oxygen supply to the brain is stopped. This can be caused by:

• cardiac arrest – when the heart stops beating and the brain is starved of oxygen
• heart attack – a serious medical emergency that occurs when the blood supply to the heart is suddenly blocked
• stroke – a serious medical emergency that occurs when the blood supply to the brain is blocked or interrupted
• blood clot – a blockage in a blood vessel that disturbs or blocks the flow of blood around your body
