The Dead Donor Rule is an important component of the protections afforded to donors in organ donations. It states that medical professionals must be certain that a patient has truly passed away before procuring their organs for transplantation. One method of assessing this is using the neurological criteria. Patients satisfying these criteria have achieved what is commonly referred to as Brain Death. However, the question of whether brain death is true death is one hotly contested in some areas of Catholic bioethics. Recently, however, new guidelines provided by the American Academy of Neurology have given rise to a new disagreement: whether these new guidelines accurately assess brain death at all. This article gives an introduction to a longer call to action, Catholics United on Brain Death and Organ Donation, which describes the issues with this new guidance and objects to its use.
