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 ...
When the brain stops receiving oxygen, ... 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 ...
The anoxic event is likely to cause damage to cytoplasmic ATP-dependent enzymes in oligodendrocytes. Because many of these enzymes play essential roles in myelin turnover, damage to these enzymes is thought to adversely affect the ability of the body to sustain myelin in white matter, leading to the demyelination of those areas of the brain ...
Lower brain oxygen levels caused by sleep apnea were linked to changes to the white matter, which could lead to cognitive problem, a new study suggests. ... or areas of brain damage. ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.

Anoxia means a total depletion in the level of oxygen, an extreme form of hypoxia or "low oxygen". The terms anoxia and hypoxia are used in various contexts: Anoxic waters, sea water, fresh water or groundwater that are depleted of dissolved oxygen; Anoxic event, when the Earth's oceans become completely depleted of oxygen below the surface levels
