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 used as an indicator of legal death in many jurisdictions, [7] but it is defined inconsistently and often confused by the public. [8] Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations.
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.

Researchers studying the brain’s final moments have gained new insight into the “wave of death” that occurs before a brain’s activity fully flatlines. When neural activity stops, it doesn ...
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.

In other areas of the brain, viable human neurons have been recovered and grown in culture hours after clinical death. [10] Brain failure after clinical death is now known to be due to a complex series of processes called reperfusion injury that occur after blood circulation has been restored, especially processes that interfere with blood ...
So while the symptoms of brain fog can be vague and all over the place, they may stem from real changes in the brain. Your brain health matters! BrainHQ rewires the brain so you can think faster ...
The test is commonly used by physicians, audiologists and other trained professionals to validate a diagnosis of asymmetric function in the peripheral vestibular system. Calorics are usually a subtest of the electronystagmography (ENG) battery of tests. It is one of several tests which can be used to test for brain stem death.
