International experts say a clinical examination demonstrating coma, brainstem areflexia and apnoea should be used to determine brain death/death by neurologic criteria.

Although the idea of brain death was first recognised in 1959 and the first clinical definition was published in 1968, there has continued to be wide variance in practice internationally and within countries.
