Addressing the Problem of Brain Death Misdiagnosis

Recent literature describes the controversy relating to brain death/death by neurological criteria (DNC), which some have referred to as "widely accepted, but not universally supported." This article provides an overview of differences in state laws relating to DNC and describes recent proposals to reform the definition of brain death. In 2023, the American Academy of Neurology (AAN) issued clinical guidelines stating that clinicians may declare a patient DNC despite evidence of neuroendocrine function - a position that directly conflicts with state law requirements for determining death. This article offers a critical analysis of AAN guidelines, an update on proposals to reform the Uniform Determination of Death Act, and explains why policy discussions should include how DNC exams occur in practice. Research suggests there are flaws with current clinical testing methods, which contributes to two separate problems: (1) false positives from insufficient testing, and (2) inadvertent misdiagnosis from unintentional errors. Together, this has produced confusion and reduced public trust in the concept of brain death. This article provides recommendations to clarify and retain the current legal standard for brain death, explains the ethical importance of accurate standards for determining DNC, and offers practical solutions to reduce errors.
