Brain injury as a result of oxygen deprivation either due to hypoxic or anoxic mechanisms are generally termed hypoxic/anoxic injuries (HAI). Hypoxic ischemic encephalopathy ( HIE ) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total.
Anoxic depolarization is a progressive and uncontrollable depolarization of neurons during stroke or brain ischemia in which there is an inadequate supply of blood to the brain. [1] Anoxic depolarization is induced by the loss of neuronal selective membrane permeability and the ion gradients across the membrane that are needed to support ...
But that isn’t the end, because it's now time for the “wave of death,” which totally alters the function and structure of the brain. “This critical event, called anoxic depolarization ...
Brain death is used as an indicator of legal death in many jurisdictions, [6] but it is defined inconsistently and often confused by the public. [7] 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 death can be in the vehicle, or following loss of consciousness to be followed by death while in a coma, having presented with anoxic brain damage. The asphyxia can be caused by facial compression, neck compression, or chest compression.
Actor Anne Heche is legally dead after suffering a "severe anoxic brain injury" due to a car accident in Los Angeles last week.
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]
"Unfortunately, due to her accident, Anne Heche suffered a severe anoxic brain injury and remains in a coma, in critical condition," read the statement, sent on behalf of the actress's family ...
