Brain death.
Current law in the United States authorizes physicians to diagnose brain death by applying generally accepted neurologic criteria for determining loss of function of the entire brain. This article offers a medical-legal perspective on problems that may arise with respect to the determination of brain death. These include the possibility of diagnostic error, conceptual disagreements that may constrain the use of neurologic criteria to diagnose death, and the conflation of brain death and loss of consciousness. This article also addresses legal aspects of the debate over whether to expand the definition of brain death to include permanent unconsciousness. Although existing laws draw a clear distinction between brain death and the persistent vegetative state, many courts have authorized removal of life support from individuals whose unconsciousness is believed to be permanent on proof that removal accords with preferences expressed before sentience was lost.
