Brain death: legal obligations and the courts.

Brain death, or death determined by neurologic criteria, has been legally adopted in all U.S. states for decades. Despite its long-established history, a lack of clear understanding has led to disputes requiring a legal forum for resolution. Recently, physicians and hospitals across the country have been impacted by a growing number of disputes about brain death. The authors offer clinicians a historical perspective on the evolution of brain death as a legal cause of death in the United States. They then review the more common legal categories of disputes encountered, including representative court cases for each. This overview provides physicians with a general legal perspective on brain death so they may better appreciate the pertinent issues if and when later confronted.
