From what I redon on wikipedia, she was living, but they chose to pull out her feeding tube. There are no cases where people came back from a persistent vegetative state. Their brains are turned into mush if they are at this point. The bizarre cases I've have all been anecdotal in news articles or some shit. Nothing reported in a journal.

Common misconception is that there have been people who have been brain dead and have regained consciousness later on. That has actually never happened. People have entered vegetative states/comas and regained consciousness, but nobody with diagnosed brain death has ever come back from it.

Schiavo was in a persistent vegetative state, which people have regained consciousness from. But you can also look up her CT scans and see that massive parts of her cortical brain tissue are completely gone. Would have been pretty unprecedented to make a full recovery from that when even moderate injuries result in chronic disability.

Please treat our language with the respect it deserves.

shoulda dosed her on lsd first to see if that'd fix it, if not then do as they did

this is the kind of errant pedantry up with which this board ought not to put

Give them lanthanum 500mg/day and manganese 40mg/day.

The brain can regenerate, but it's normally prevented from doing so by too much iron or zinc and too little copper or manganese. Lanthanum should fix the iron zinc and copper imbalances if the nutrition is otherwise adequate and the brain should be able to repair itself if you add manganese.

No, there have been straight up people completely die, brain, heart and all, and wake up in the morgue an hour or so later. Science still hasn't explained some of those documented cases. I remember studying them in a bio class in college as unexplained scientific "miracles".

>>10588843
Why don't we just take iron and zinc completely out of our diets so our brains can get better?

>Why don't they try to jolt people in vegetarian states out of it by dosing them with say crack, meth, adrenaline, or electroconvolusive therapy?

In most of those cases the brain death diagnosis is a poor diagnosis of a deep coma or similar state, where brain activity still occurs. True brain death, where there is no brain activity (including for involuntary actions) has never been recovered from.

There is one documented case of it happening. Lazarus of the Bible was brought back by the greatest doctor known to mankind. Lazarus was about as a brain dead as anybody can ever get.

>>10588884
What about this guy who was declared brain dead by not one, not two, not three, but four different doctors? Are you telling me that they all suck?

If you bothered to read your article you would see that they detected faint brain waves. That’s brain activity, and the four physicians gave a faulty diagnosis.

I actually read through this list before making my post.

It’s been written by someone who doesn’t understand what brain death is, which is easily seen by him referring to someone as being in a coma and wouldn’t recover as brain dead, and the same for someone in a vegitative state. Most are of people who were in comas and pronounced they wouldn’t recover (still had brain activity but it was predicted they wouldn’t recover back to consciousness). For the few that were actually a brain death diagnosis, the coma was misdiagnosed as brain death (brain activity was not detected but was still present, just weak enough to not be detected without further investigation by a neurologist).
The only one that stands out is the 2008 Virginia women, though I am pretty confident further, more rigorous testing by a neurologist would have found weak activity, similar to the case >>10588903 brings up.

Again, brain death is only diagnosed when there is no brain activity. Weak brain activity in deep comas and vegitative states do not constitute brain death, even when enough time has passed that it’s safe to say that the patient won’t recover.

Doctors aren’t infallible, and these decisions are probably rushed through faster than they should be so that organ donations can be made while they have the greatest chance of success.

While manganese does readily take place of iron in molecules like hemoglobin, I don't think they would work the same way. I don't know what could replace zinc. I suppose you would die. It's the dysregulation that is the problem, you can suffer from iron overload and be anemic. But it is true we probably eat too much iron anyway.

>>10588850
Then they probably weren't brain dead - something about their physiology or cause of death meant that their brain tissue wasn't destroyed.

Brain death requires EEG and loss of all reflexes and autonomic control. When people call time of death, they're mainly just looking at heart activity and breathing.

Except there's nothing wrong with that sentence.

>grammar wars again

Yes, we are having a discussion on /sci/, which should garner some grammatical tact and respect. However, let's not forget that we are also on 4chan. It strikes me as the paradoxical equivalent of shopping for a microscope at Walmart.
