The "brain death" standard as a criterion of death is closely associated with the need for transplantable organs from heart-beating donors. Are all of these potential donors really dead, or does the documented evidence of patients destined for organ harvesting who improve, or even recover to live normal lives, call into question the premise underlying "brain death"? The aim of this paper is to re-examine the notion of "brain death," especially its clinical test-criteria, in light of a broad framework, including medical knowledge in the field of neuro-intensive care and the traditional ethics of the medical profession. I will argue that both the empirical medical evidence and the ethics of the doctor-patient relationship point to an alternative approach toward the severely comatose patient (potential braindead donor).Lay Summary: Though legally accepted and widely practiced, the "brain death" standard for the determination of death has remained a controversial issue, especially in view of the occurrence of "chronic brain death" survivors. This paper critically re-evaluates the clinical test-criteria for "brain death," taking into account what is known about the neuro-critical care of severe brain injury. The medical evidence, together with the understanding of the moral role of the physician toward the patient present before him or her, indicate that an alternative approach should be offered to the deeply comatose patient.
The introduction of the “brain death” criterion constitutes a significant paradigm shift in the determination of death. The perception of the public at large is that the Catholic Church has formally endorsed this neurological standard. However, a critical reading of the only magisterial document on this subject, Pope John Paul II's 2000 address, shows that the pope's acceptance of the neurological criterion is conditional in that it entails a twofold requirement. It requires that certain medical presuppositions of the neurological standard are fulfilled, and that its philosophical premise coheres with the Church's teaching on the body-soul union. This article demonstrates that the medical presuppositions are not fulfilled, and that the doctrine of the brain as the central somatic integrator of the body does not cohere either with the current holistic understanding of the human organism or with the Church's Thomistic doctrine of the soul as the form of the body. Summary The concept of “brain death” (the neurological basis for legally declaring a person dead) has caused much controversy since its inception. In this regard, it has been generally perceived that the Catholic Church has officially affirmed the “brain death” criterion. The address of Pope John Paul II in 2000 shows, however, that he only gave it a conditional acceptance, one which requires that several medical and philosophical presuppositions of the “brain death” standard be fulfilled. This article demonstrates, taking into consideration both the empirical evidence and the Church's Thomistic anthropology, that the presuppositions have not been fulfilled.
“Brain death” (understood in the sense of “whole brain death” and not in the sense of “brainstem death”) was introduced into clinical practice in 1968 when the Harvard Ad Hoc Committee defined irreversible coma as a new criterion for death (understood in the full sense of the word). According to the Uniform Determination of Death Act (UDDA), promulgated in 1981 by the President’s Commission (which also formally advanced the first conceptual rationale for brain death), the legal declaration of death using the brain death standard requires the irreversible cessation of all functions of the entire brain, including the brain stem. The brain death standard has since evolved, however, to include significant modifications even though, on a literal reading, its clinical test criteria have remained unchanged. This article gives an account of why and how the brain death standard has been updated, leading to the currently practiced guidelines for the determination of brain death put forth by the American Academy of Neurology. According to the updated standard, the presence of certain brain or spinal cord functions does not invalidate the diagnosis of brain death. By analyzing these guidelines critically on the basis of scientific realism and Thomistic hylomorphism, this article demonstrates that the updated brain death standard contradicts both the UDDA and the tenets of sound anthropology held by the Catholic Church. Summary: This article examines the evolution of the “brain death” standard from the time of its introduction by the Harvard Committee until the current guidelines established by the American Academy of Neurology. This evolution consists mainly of a selective discarding of certain brain and spinal cord functions that are deemed insignificant. Based on the principles of scientific realism and a Thomistic substance view of human nature, this article shows that the evolved standard contradicts both the Uniform Determination of Death Act definition of brain death and the fundamental tenets of Christian anthropology as taught by the Catholic Church.
