Reperfusion injury, sometimes called ischemia-reperfusion injury (IRI) or reoxygenation injury, is the tissue damage caused when blood supply returns to tissue (re-+ perfusion) after a period of ischemia or lack of oxygen (anoxia or hypoxia).
Cerebral hyperperfusion syndrome, also known as reperfusion syndrome, is a dysregulated state of cerebral blood flow following the restoration of arterial blood flow to the brain, usually following treatment of carotid artery stenosis. [1]
Brain injury as a result of oxygen deprivation either due to hypoxic or anoxic mechanisms is generally termed hypoxic/anoxic injury (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.
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.
Ischemia-reperfusion (IR) tissue injury is the resultant pathology from a combination of factors, including tissue hypoxia, followed by tissue damage associated with re-oxygenation. IR injury contributes to disease and mortality in a variety of pathologies, including myocardial infarction , ischemic stroke , acute kidney injury , trauma ...
Reperfusion is the restoration of blood flow to an organ or tissue after having been blocked, and may refer to: Reperfusion injury , tissue damage caused when blood supply returns to the tissue Reperfusion therapy , the medical treatment that restores blood flow through blocked arteries, typically after a heart attack
Schadenfreude (/ ˈ ʃ ɑː d ən f r ɔɪ d ə /; German: [ˈʃaːdn̩ˌfʁɔʏ̯də] ⓘ; lit. Tooltip literal translation "harm-joy") is the experience of pleasure, joy, or self-satisfaction that comes from learning of or witnessing the troubles, failures, pain, suffering, or humiliation of another.
Neuroglycopenia is a shortage of glucose (glycopenia) in the brain, usually due to hypoglycemia. Glycopenia affects the function of neurons, and alters brain function and behavior. Prolonged or recurrent neuroglycopenia can result in loss of consciousness, damage to the brain, and eventual death. [1] [2] [3]
