The diagnosis of brain death (BD) is legally and medically accepted. Recently, several high-profile cases have led to discussions regarding the integrity of current criteria, and many physiologic problems have been identified to support the necessity for their reevaluation. These include a global variability of the criteria, the suggestion of a clinical “hierarchy,” and the resultant approximation of BD. Further ambiguity has been exposed through case reports of reversible BD, and an inconsistent understanding from physicians who are viewed as experts in this domain. Meeting BD criteria clearly does not equate to a physiologic “death” of the brain, and a greater community perspective should be considered as the dialogue moves forward.
