I continue to be puzzled why the concept of "no blood flow to the brain" is so very difficult for so many people to grasp and understand-- not just here, but in general society.
Dr. Fisher's report clearly says a rasdionuclide SPECT blood flow diagnostic test was done, with no flow. There is nothing more definitive than that, save doing an autopsy to SEE the dead brain.
When intracranial pressure exceeds blood pressure for long enough, brain tissue dies. The flow scan will show the tracer in the carotids, and not penetrating any tissue inside the skull. The tissue is not just "not perfused"-- it is not in suspended animation, waiting for blood flow-- the brain tissue is dead.
Back in another thread, a very insightful poster (I can't remember who :blushing:-- Donjeta or Beginner's Luck? ) made the analogy that if it was a finger or limb that did not have any blood flow to it for a month, it would be plainly obvious to anyone with eyes what the state of deterioration of the limb is. You can cut off a dead limb, and the person might live. But without a brain, there is no life. No possibility of recovery. At all. Ever. Functional decapitation.
There is also a rather persistent idea in a large swath of the public that when circulation stops to the brain, it goes into a state of "suspended animation". I have read many comments about waiting for "the brain swelling" to go down, and circulation will be restored, the person will wake up, etc.
It is just so puzzling to me how so many people don't have the most basic grasp of what "cell death" means. Is it because we are so urbanized as a society that a lot of people are removed from the realities of anatomy, birth, death, etc? Not to be too blunt, but why don't otherwise rational people realize that human beings will deteriorate and decompose, just like any other living organism? Have most people really never seen any kind of decomposition of a living organism? Just baffling to me.
But then, some first time moms who watch too many labor and delivery reality shows think labor happens in about half an hour! It's like we humans have urbanized and compartmentalized ourselves so much we think we are immortal, and not subject to the same laws of nature and science as any other living thing! Baffling.
