Autopsy studies in patients who have been declared brain dead are rare. Total brain necrosis ("respirator brain") has been a common finding in the distant past. The time to brain fixation has been shortened as a result of timely organ transplant protocols, therefore the neuropathologic findings may be different than previously described.
