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.

Cooling treatment alone has permitted recovery after 17 minutes of clinical death at normal temperature, but with brain injury. [17] Under laboratory conditions at normal body temperature, the longest period of clinical death of a cat (after complete circulatory arrest) survived with eventual return of brain function is one hour. [18] [19]
A 2011 autopsy-based study found that sudden death was attributed to a cardiac condition in 79.3% of cases, and was unexplained in 20.7%. [3] In the Philippines, sudden adult death syndrome (or in their term, bangungot) is mainly caused by the Brugada syndrome. [14]
Locked-in syndrome may mimic loss of consciousness in patients, or, in the case that respiratory control is lost, may even resemble death. People are also unable to actuate standard motor responses such as withdrawal from pain ; as a result, testing often requires making requests of the patient such as blinking or vertical eye movement.
The suggested new definition of death was the "irreversible loss of the capacity for consciousness, combined with irreversible loss of the capacity to breathe". It was stated that the irreversible cessation of brainstem function will produce this state and "therefore brainstem death is equivalent to the death of the individual". [2]
The sudden passing of the wife of U.S. Rep. Andy Barr, is putting the spotlight on floppy valve syndrome, listed as the cause of her death.
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. [1] This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3]
