Why is a person declared dead when their heart stops functioning even though their brain is still functioning?

As soon as the heart stops it's game over for your brain. You have less than a minute till the brain will shut down due to the lack of oxygen. Similarly you can be declared brain dead but still have your heart beating.
Like I said, as soon as you 'flatline' it's essentially game over. Obviously attempts of revival can succeed in cases but you only have a short window after the 'time of death' i.e the 'flatline' to do so.
There was one case (off the top of my head) where someone went around 3 hours I think it was before they were able to restart her heart. That was only due to the conditions in which the body was preserved in the accident (she was skiing and the body was cooled and slowed down enough in the ice for her to be able to have the brilliant medical staff bring her back hours later).

Why do doctors consider a person dead when the brain is not working but the heart is still beating?
This is because being dead is defined as stoppage in the functioning of brain and it is not having any relation with the functioning of heart. If the heart stops beating then there is no supply of oxygen rich blood to the brain and hence the brain dies and henceforth the person is declared dead.

Why people declared dead when the brain stops functioning?
Because there's got to be a line somewhere at which point a doctor can say "this person is now dead." It used to be when the heart stopped, but we've since discovered that it's possible to restart the heart if it's done quickly enough.

Did Ted Bundy have anything officially declared to be medically wrong with his brain?
Ted was a person that needed medical attention since his early days. Instead, he thought he was a smart person. When he was caught by a stupid mistake by overspeeding, he defended himself in court, which is a stupid thing to do, but anyways he really thought he was smart and never declared a crazy brain.
