Practice guidelines for determining brain death have long been established by the American Academy of Neurology. Is there uniformity across the United States in adhering to these standard guidelines? How might the proper clinical exam for brain death declarations be adversely persuaded? Dr. David Greer, assistant professor of neurology at Harvard Medical School, directed a national survey of neurology and neurosurgery programs to analyze policies for making brain death declarations. Dr. Greer details his research with host Dr. Mark Nolan Hill.
