  1. The fact is that:

    Currently, “brain death” is understood as a pathological condition associated with total brain necrosis


    Necrosis is irreversible. In case of necrosis of any tissue, it is removed, the limbs are amputated. Do you remember the rotten apple?

    So, no, it's irreversible.�

    But the brain is a tenacious thing, even a prolonged coma does not always mean a lack of consciousness and an irretrievable loss of personality.

  2. The point is how extensive the necrotic changes in brain tissues and cells are. If all the nerve cells in the brain are dead, any memory elements of individual cells and the system are lost forever, and no procedures can revive these cells and reproduce the memory they generate, this is the end.
    Can it be that only part of the brain has died, a person is in a deep coma and is diagnosed with “brain death”? Probably not, because a CT scan, encephalogram, and other dynamic brain studies will reveal this. If brain necrosis really occurs, this condition is irreversible.
