The whole idea of "brain death" is fraudulent. There is no empirical support for it, and there is no agreed definition of it. The concept was invented by doctors who wanted to justify taking organs out of still-living people. See the paper at this site: http://www.prolifetechnology.org/proceedings/2007/slides/byrne.pdf
“The whole idea of “brain death” is fraudulent. ... there is no agreed definition of it.”
If
1. there is *no* EEG activity; and
2. there is no CBF (cerebral blood flow); and
3. there is no effect on the heart rate of a 1mm injection of atropine
then the patient is generally determined to be “brain dead.” If she had *all* of these indicators and then woke up, I agree that it is truly a miracle.
