Argument by authority, eh?
I have discussed physiology, you law and rhetoric - hardly have you made medical or scientific arguments, by your own admission.
You claim to know a lot about her condition. Perhaps you can tell us how you are privy to such detail You have apparently seen her medical records. That’s probably where you saw the results from the brain analyzing machine that can tell when a brain is liquified vs being jellied or mushy or A-OK.
"He who knows what he knows not is wise, follow him...He who knows not what he knows not is a fool -- shun him".
It is evident you know not what you know not. All the best of luck, but also remember it is better to be silent and thought a fool than speak up and remove all doubt. I have no doubt when it comes to your statements, and by extension...you. Good day.
We do have brain analyzing machines. These are called reflexes. They do not depend on whether one is awake, sleeping, ill or well. When the brain is functioning “alive” these reflexes are intact. Loss of the reflex reveals no brain function.
In addition there are multiple scans that can be done that prove no blood flow to the crucial areas of the brain, EEGs that can show lack of electrical activity in the brain, etc.
It seems you do not want to hear the truth, just hold to your own opinion. As is famously said, you have the right to be wrong.
