Abstract'Brain death' is defined pathophysiologically as intracranial circulatory arrest. The morphological features of brain death include cerebral edema, absence of reactive changes, and--after an interval of 15-36 h--the morphological hallmarks of respirator brain: edema, global softening of the brain, dusky discoloration of the gray matter, and often necrotic and sloughing tonsillar herniations. The following implications of brain death for forensic medicine are discussed: discriminating between respirator and autolytic brain, declaration of death, determining the time of brain death versus the time of the traumatic event leading to brain death, and neuropathological control of the clinical diagnosis of brain death. These issues are elucidated and their bearing on forensic practice is illustrated by several real-life situations. Thus, neuropathological examination in the case of clinically diagnosed brain death is--without doubt--necessary in order to answer several questions often or regularly expected.
