In the UK it is not considered to be of value because any continuing activity it might reveal in parts of the brain above the brain stem is held to be irrelevant to the diagnosis of death on the Code of Practice criteria. [23] The diagnosis of brain death is often required to be highly rigorous, in order to be certain that the condition is ...
The change of use, in the UK, to criteria for the diagnosis of death itself was protested immediately. [17] [18] The initial basis for the change of use was the claim that satisfaction of the criteria sufficed for the diagnosis of the death of the brain as a whole, despite the persistence of demonstrable activity in parts of the brain.

Dead on arrival (DOA), also dead in the field, brought in dead (BID), or dead right there (DRT) are terms which indicate that a patient was found to be already clinically dead upon the arrival of professional medical assistance, often in the form of first responders such as emergency medical technicians, paramedics, firefighters, or police.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
The phenomenon has been observed to occur several minutes after the removal of medical ventilators used to pump air in and out of brain-dead patients. [4] It also occurs during testing for apnea—that is, suspension of external breathing and motion of the lung muscles—which is one of the criteria for determining brain death used for example by the American Academy of Neurology.
Brain death is a different condition than persistent vegetative state. [2] Due to better seat belt use, bicycle helmets, and the general decrease in violent crime, there are lower numbers of brain deaths now than historically. Donation after cardiac death (DCD) is a new protocol applied when there is severe neurologic injury but the patient ...
Most legal determinations of death in the developed world are made by medical professionals who pronounce death when specific criteria are met. [4] Two categories of legal death are death determined by irreversible cessation of heartbeat (cardiopulmonary death), and death determined by irreversible cessation of functions of the brain (brain death).
Per the United Kingdom Medical Royal Colleges, a diagnosis of brain death is a two-fold process including 1) identifying the cause of irreversible brain damage and excluding reversible causes of brain damage and 2) conducting a series of clinical and laboratory tests to assess brain stem function.
