Do you have any source other than a tabloid zealot who writes books declaring brain death diagnosis is a concocted scheme to exploit organs for profit?
Dr. Machado is my source. And as far as I'm aware he has never advocated that brain death is a "scheme."
If you would read the article I linked, it clearly quotes Dr. Machado:
I must affirm that I am a defender that brain death means death of the human being, and it is a state with no hope of recovery. Moreover, I am a Corresponding Fellow of the American Academy of Neurology (AAN), and I consider that AAN Criteria for Brain Death Diagnosis represent one the most outstanding and reliable Guidelines in the world for confirming the diagnosis of brain death.
