Can someone come back to life if they are brain dead?
Well if someone is brain dead they are not literally dead they just no longer have human interaction
Nope, if they brain is dead the person is dead
idk for certain but i have heard that if they are brain dead for only a short time, like less than a min or so that they could come back
yes,they will just be vegitable.
Yes. With the help of God anything is possible!
I actually know a person who was declared brain dead and then later was... not. But you've no reason to believe a stranger on the internet.
