Evolution of the Concepts of Brain Death and Brain Stem Death

Abstract

Brain stem death has remained a topic of contention among physicians and laypersons for many years. The evolution of the current definition of brain stem death has been the end result of decades of scientific study and deliberation. Although the concept has been known historically, a scientific probe into the matter had been made possible only during the late 20th century. This led to a healthy discussion regarding the obscure nature of brain stem death among experts on different continents, leading to the current definition provided by the American Association of Neurology in 2010. This review article aims at shedding light on the institution of brain stem death and the evolution of the definition, as we know it today.
