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 induced by the loss of neuronal selective membrane permeability and the ion gradients across the membrane that are needed to support neuronal activity. Normally, the Na+/K+-ATPase pump maintains the transmembrane gradients of K + and Na + ions, but with anoxic brain injury, the supply of energy to drive this pump is ...
The hyperbaric oxygen treatment eliminates carbon dioxide from the brain, while the standard oxygen treatment normalizes carboxyhemoglobin levels. Another preventative measure one can take is to be on bed rest and abstain from stressful and strenuous procedures for the first 10 days after an extended hypoxic event.
The brain damage caused by radiation depends on where the brain tumor is located, the amount of radiation used, and the duration of the treatment. Radiosurgery can also lead to tissue damage that results in about 1 in 20 patients requiring a second operation to remove the damaged tissue.
Actor Anne Heche is legally dead after suffering a "severe anoxic brain injury" due to a car accident in Los Angeles last week.
Newborn hypoxic-ischaemic brain injury differs from injury in the adult brain in several ways: NMDA receptor toxicity is much higher in the immature brain. [18] Apoptotic mechanisms including activation of caspases, translocation of apoptosis-inducing factor and cytochrome-c release are much greater in the immature than the adult.
