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.
Reperfusion injury plays a major part in the biochemistry of hypoxic brain injury in stroke. Similar failure processes are involved in brain failure following reversal of cardiac arrest; [3] control of these processes is the subject of ongoing research.
Hypoxic ischemic encephalopathy has many causes and is defined essentially as the reduction in the supply of blood or oxygen to a baby's brain before, during, or even after birth. It is a major cause of death and disability, occurring in approximately 2–3 per 1000 births and causing around 20% of all cases of cerebral palsy .
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.
The concept of the ischemic penumbra was developed in Lindsay Symons laboratory, The National Hospital, Queens Square, London, in 1976 by combined focal measurements of neurofunction, blood flow and extracellular K + in the baboon brain following a MCA occlusion. Critical levels of blood flow was observed for function and energy metabolism.
Prolonged hypoxia induces neuronal cell death via apoptosis, resulting in a hypoxic brain injury. [34] [35] Oxygen deprivation can be hypoxic (reduced general oxygen availability) or ischemic (oxygen deprivation due to a disruption in blood flow) in origin. Brain injury as a result of oxygen deprivation is generally termed hypoxic injury.
HIGH POINT, N.C. (WGHP) — The holidays are a time to surround yourself with loved ones. The Dulin family spent last Christmas huddled around a hospital bed as Caleb Dulin recovered from a brain ...
[4] She was also the recipient of a Faculty Research Initiative Award worth $20,000 for her study Mechanistic pharmacological studies of striato-pallidal-thalamic integrity after cardiac arrest induced hypoxic ischemic brain injury.
