Is Death Reversible? Is it the right time to find out?

misty mort 3Death is defined as the termination of all biological functions that sustain a living organism.

Brain death, the complete and irreversible loss of brain function (including involuntary activity necessary to sustain life) as defined in the 1968 report of the Ad Hoc Committee of the Harvard Medical School, is the legal definition of human death in most countries around the world.

Either directly through trauma, or indirectly through secondary disease indications, brain death is the final pathological state that over 60 million people globally transfer through each year.

We are repeatedly told through the medical establishment (as well as through popular culture, in recent public cases such as those surrounding Jahi McMath and Bobbi Kristina Brown) that brain death is “irreversible” and should be considered the end of the line.

Or is it?

Have we come to a technological point where we are able to “push the envelope” to see if this is truly the case?

While it is true that human beings lack substantial regenerative capabilities in the CNS, many non-human species, such as amphibians, planarians, and certain fish, can repair, regenerate and remodel substantial portions of their brain and brain stem even after critical life-threatening trauma.

These epimorphic capabilities have been leveraged experimentally in past decades to perform complex brain transplantation in organisms such as salamanders, as well as to study the dynamics of memory storage.

Extensive study over the last century has shed a substantial amount of knowledge on the processes of epimorphic, intercalary regeneration and the unique and multi-mechanistic dynamics that are involved in re-starting a defined generative developmental pattern to specifically fill in missing or damaged tissues and organs in a living organism.

Additionally, recent studies on complex brain regeneration in organisms such as planaria, amphibians, and holomorphic insects, have highlighted unique findings in relation to the storage of memories following destruction of the entire brain, which may have wide ranging implications for our understanding of consciousness and the stability of memory persistence. Investigations into the areas of biologic information processing in aneural organisms, non-neural human tissues, and single cell organisms that form multi-cellular structures, add to a fascinating portfolio of questions, and potentially challenge the notion of the brain as the sole repository of long-term encoded information.

Brain ImageDespite the label of irreversibility associated with the 1968 Harvard Ad Hoc Committee definition, there are several documented cases in the literature of potential brain death reversal, primarily associated with younger subjects whose CNS maintained some degree of underlying neuroplasticity.

As most thought leaders in the space acknowledge that residual “nests” of neuronal activity and residual blood flow do indeed exist in the recently diagnosed brain dead, it makes sense that such transitions are theoretically possible with the right neuro-regeneration and remodeling tools.

Additionally, it is widely acknowledged that supported brain dead subjects can continue to maintain their own circulation, digestion, food metabolism, excretion, hormonal balance, growth, sexual maturation, fetus gestation, wound healing, and spike a fever.

We don’t think much about it any more, but the first cardiac defibrillation, mechanical pulmonary respiration, and complex organ transplants, all made their public debuts around a century ago.

So here we sit in 2016, at a very unique moment in scientific history where the convergence of the tools of regenerative biotechnology, resuscitation / reanimation research, and clinical neuroscience have placed us on the verge of being to answer some unique, profound, and controversial questions.

The question is do we take the next steps?

I believe we should.
