Finally, in Section IV, I explore ways of synthesizing our definitions of death with what we care about. It is vital that we examine the evaluative content in our concepts and practices relating to death, and reflect on what it is that we value or should value in persons. [9][10] The Harvard criteria gradually gained consensus toward what is now known as brain death. Also, a radionuclide cerebral blood flow scan that shows complete absence of intracranial blood flow must be considered with other exams – temporary swelling of the brain, particularly within the first 72 hours, can lead to a false positive test on a patient that may recover with more time. brain [brān] that part of the central nervous system contained within the cranium, comprising the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon); it develops from the embryonic neural tube. A brain-dead individual has no clinical evidence of brain function upon physical examination. This also help clears up some of the conceptual confusion as to whether such operations would be ‘head transplants’ or ‘body transplants’.55 If the brain is in some way what matters, then what matters in such a transplant is the head, not the body. The higher brain standard of death identifies key aspects of what makes us persons, and then identifies the death of the source of those aspects as the death of the person. In such a future, it is conceivable that we may come to value the personality of persons more. One of the fundamental problems with the identity theory of mind and thus with both the total brain and the higher brain standards is that the mind is not necessarily identical with the brain. Legal recognition of the brain-based standard would remove the doubt that exists in some states over the use of patients without brain functions as organ donors. The Commission sought to address a need for a legal definition of death which could incorporate advances made by new technologies that could perform necessary bodily functions.14 There was a wide agreement between physician testifiers to the Commission that a definition of death which referred to irreversible loss of brain functions was required.15 Among the reasons given for such a definition included the following: Such a law would establish the legality of pronouncing death based on brain criteria. President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research Defining Death: Medical, Legal and Ethical Issues in the Determination of Death, [hereinafter Commission] 13–16 (1981).

In virtually every case death may be sufficiently determined by what I shall call the ‘death criteria trifecta’ of cardiopulmonary, total brain, and higher brain criteria. It is conceivable that in such a world embodied persons may be thought of as the only ‘true’ persons and the gap between biological death and the death of persons will become narrower. See John Bickle, Multiple Realizability, The Stanford Encyclopedia of Philosophy, http://plato.stanford.edu/archives/spr2013/entries/multiple-realizability/ (last accessed Oct. 17, 2016). The whole-brain-death criterion is said by its proponents to focus on the integrated functioning of the organism as a whole. The Commission recognized this in its report and seemed to base its decision to adopt the total brain standard tacitly on problems with the higher brain criterion.51 Higher brain standards face measurement problems given currently existing medical knowledge and technology. If or when such changes in our values and practices occur, our conceptions of personal identity may thus shift as well. ©2009—2020 Bioethics Research Library Box 571212 Washington DC 20057-1212 202.687.3885 Using the current total-brain death standard, legally a patient must be totally brain dead in order to donate organs that they would not be able to live without. of brain death per se-regardless of the focus on "higher," "stem" or "whole"-is fundamentally flawed. This is essentially an application of the identity theory of mind. and (2) How can we determine that it has occurred? Indeed, in 2008 the President's Council on Bioethics went so far as to advocate for a ‘total brain failure/standard as opposed to the total brain death standard, in part for measurement reasons.52 However, given the current medical technology available, it seems that neurological criteria represent the most pragmatic set of standards for what constitutes death. [1][2][3][4] It differs from persistent vegetative state, in which the person is alive and some autonomic functions remain. A person in a vegetative state is alive and may recover to some degree, given time. As I will argue, what we think of as constituting death is shaped by what we value in persons. It is this latter possibility in particular that highlights a fundamental problem with identity views such as the total or higher brain conceptions of death. Today, both the legal and medical communities in the US use "brain death" as a legal definition of death, allowing a person to be declared legally dead even if life support equipment keeps the body's metabolic processes working. 13, 23 (1975). When mechanical ventilation is used to support the body of a brain dead organ donor pending a transplant into an organ recipient, the donor's date of death is listed as the date that brain death was diagnosed. Higher brain functions are the operations of the brain that stand at the pinnacle of evolution and are largely unique to humans. [15][16] The Australia and New Zealand Intensive Care Society (ANZICS) states that the "determination of brain death requires that there is unresponsive coma, the absence of brain-stem reflexes and the absence of respiratory centre function, in the clinical setting in which these findings are irreversible. As the Commission notes: “the traditional “vital signs” of heartbeat and respiration were merely surrogate signs with no significance in themselves.24 On this view, the heart and lungs are not important as basic prerequisites to continued life but rather because the irreversible cessation of their functions shows that the brain had ceased functioning.”25 Insofar as the traditional criteria indicated the change that really mattered, they were helpful in determining death. The Trump Administration’s Flawed Decision on coronavirus Vaccine Injury Compensation: Recommendations for Changes, Transparency too little, too late? An answer to this question will consist of a definition (or conceptualization). Ch. Law Serv. (Cal. Edward O. Wilson, Consilience: The Unity of Knowledge 105 (1999). In these cases, death shall be declared, and the time of death fixed, solely upon the basis of cardio-respiratory criteria …28. See also H. Tristram Englehardt, Jr., Defining Death: A Philosophical Problem for Medicine and Law, 112 Ann. Thus, the electronic process related to encoded memories, links between memories, predispositions, and even consciousness and pain—all the things that make us persons—could be replicated through computers and without brains. Differences in operational definitions of death have obvious medicolegal implications (in medical jurisprudence and medical law). The concept was `sold' to the public on the basis of whole brain death, the President's Commission rejecting the alternative higher brain definition (declaring death once consciousness is permanently lost). These definitions include historical and current standards, but also proposed alternative standards. The patient should have a normal temperature and be free of drugs that can suppress brain activity if the diagnosis is to be made on EEG criteria. It should be noted, however, that the President's Commission does not have the power to make laws. [6] Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations. Complaint, McMath v. Rosen. As I will argue, the total brain criterion represents an advance over the old criteria in the sense that the brain is what matters in death. Sam Kean, The Audacious Plan to Save This Man's Life by Transplanting His Head, The Atlantic, Sept. 2016. In Section III, I examine what we care about in the death of a person. The organism is the body, which is not essential to who a person is. Health Resources and Services Administration, Organ Procurement and Transplantation Network, https://optn.transplant.hrsa.gov/ (last accessed Dec.17, 2015). As James Bernat has argued, neurological criteria currently represent optimum policy as they encompass ‘the critical functions of the organism as a whole’.53. However, these and other practical problems in determining higher brain death do not prevent us from pragmatically defining death. Two recent cases have sent this sensitive and thorny issue once again into the media spotlight. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. The higher-brain-death criterion centers on the irreversible absence of a capacity for consciousness. [22], CT angiography is neither required nor sufficient test to make the diagnosis. The personal identity standards come even closer to matching what we care about, and adherence to those standards would bring us perhaps as close as possible to adequate criteria for death. Human death is described as being different from the death of other life forms, in part because of the different types of functioning that persons have and in part because of certain duties and customs we (at least in the West) have toward other persons. Brain death: Irreversible cessation of all functions of the entire brain, including the brain stem. [29], "Brain-dead" redirects here. Further precision would be obtained if we were to one day move to utilize the higher brain criterion instead. It is the complete stopping of all brain function and cannot be reversed. Brain dead patients can be supported with ventilators and blood pressure can be artificially maintained while the heart continues to pump blood, allowing for donation of organs. This will include not only what we currently value in persons, but also what we would value if our beliefs were fully consistent. The organism is the physical body, the ‘housing’ of the person and what is left behind after a person dies. While the enormous need for organs does not influence the truth of the matters as to what we value in persons or what constitutes death, our legal and social institutions must take the need for organs into account in developing beneficent social policy. As we have seen, this is because we do not value all parts of the brain, and thus total brain death is not necessary for death of the person, only sufficient. Brain death definition, complete cessation of brain function as evidenced by absence of brain-wave activity on an electroencephalogram: sometimes used as a legal definition of death. L. Rev. This means they will not regain consciousness or be able to breathe without support. Coma: A state of profound unresponsiveness as a result of severe illness or brain injury. Brain death - anguish for the family Patients in a coma do not open their eyes or speak, and they do not exhibit purposeful behaviors. This report was the basis for the Uniform Determination of Death Act, which has been enacted in 39 states of the United States. The aspects of the mind that we care about—personality, memory, consciousness, and so on—are thus traceable in some way to particular operations of the brain, operations which themselves can be performed in other ways. With the further development of technology, these criteria have become more imperfect as measures of death. There are over 122,000 candidates awaiting organ donation.56 As it stands, only 18,000 donations are made each year from deceased donors, despite a much larger pool of potential donors.57 It is estimated that an average of 22 people die in the USA each day due to a shortage of organs that they desperately need in order to survive.58 One of the largest obstacles in the way of increasing the number of donations is the dead-donor rule, which proscribes doctors from procuring organs for donation in a way which causes death.59 This rule requires death for organ donation and thus our conception of what constitutes death will be vitally important. That command center of the body that regulates the central nervous system is unable to perform. A person who is brain dead is dead, with no chance of revival. It means that, as a result of severe trauma or injury to the brain, the body’s blood supply to the brain is blocked, the brain dies, and it cannot be revived. What guidance does HIPAA offer to providers considering familial risk notification and cascade genetic testing? [14] This new definition, the irreversible loss of the capacity for consciousness and for spontaneous breathing, and the essentially unchanged 1976 tests held to establish that state, have been adopted as a basis of death certification for organ transplant purposes in subsequent Codes of Practice. Such is the case with anencephaly. Any injury that causes brain death injures the entire brain and its function. Death went hand in hand with the loss of the capacity to breathe or cessation of the heart pumping blood. Abstract. Brain death is death. Other situations possibly requiring confirmatory testing include severe facial trauma where determination of brainstem reflexes will be difficult, pre-existing pupillary abnormalities, and patients with severe sleep apnea and/or pulmonary disease. Such cases will occur when medical technology creates a gap between the body and death. 587 (1975); Jeff McMahan, The Metaphysics of Brain Death, 9 Bioethics 91, 102 (1995). American Academy of Neurology. None of the patients recovered. However, there is a mismatch between our values and our legal definition of death. [24] The continuing function of vital organs in the bodies of those diagnosed brain dead, if mechanical ventilation and other life-support measures are continued, provides optimal opportunities for their transplantation. The higher brain standard of death identifies key aspects of what makes us persons, and then identifies the death of the source of those aspects as the death of the person. The idea of these transplants, as of yet not successfully implemented, is to transplant a patient's head on to the body of a donor (who is brain dead).54 In such a case, the death of the brain in some way is what counts as the death of the person. The brain also produces hormones to control individual organ function. The reverse statement, that all cases of death are cases of total brain death, is thus not addressed. The higher brain standard will more closely mirror what we care about, as it tracks the portions of the brain which produce memories, consciousness, and personality, all of which constitute what we ultimately care about in persons. The value for the EEG test is reported as "53-80, 4/97". Reflexes include pupillary response (fixed pupils), oculocephalic reflex, corneal reflex, no response to the caloric reflex test, and no spontaneous respirations. That is, the mind is multiply realizable because it can conceivably be instantiated without a brain. The philosophical investigation of human death has focused on two overarching questions: (1) What is human death? Technological advances seem as if they will inevitably make this question inescapable. In the vast majority of cases, traditional cardiopulmonary standards for death will be sufficient.49 Furthermore, as the Commission noted in its Defining Death report, ‘The [total] brain-based standard is after all, merely supplementary to the older [cardiopulmonary] standard, which will continue to be adequate in the overwhelming majority of cases in the foreseeable future’.50 Indeed, it will be in the hard cases that a brain-based standard becomes necessary. This includes no response to pain and no cranial nerve reflexes. The first question is ontological or conceptual. ‘Body transplant’ would thus be more apt, as the body would be another transplanted part (albeit majority part) such as a liver or hand. The total brain standard is what every group espousing a brain-based definition can agree on, in which case it is adopted as a politically pragmatic way of distinguishing the dead from the living.
