Global cerebral ischemia – A complete stoppage of blood flow to the brain. Cerebral infarction – A "stroke", caused by complete oxygen deprivation due to an interference in cerebral blood flow which affects multiple areas of the brain. Cerebral hypoxia can also be classified by the cause of the reduced brain oxygen: [23]
It has been found to increase oxygen consumption in the brain, apparently in connection to ATP metabolism, and increases the activity of adenylate kinase in rat brains. [ 26 ] [ 27 ] Piracetam, while in the brain, appears to increase the synthesis of cytochrome b5 , [ 28 ] which is a part of the electron transport mechanism in mitochondria .
Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2) at increased partial pressures.Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes.
Brain trauma or stroke can cause ischemia, in which blood flow is reduced to inadequate levels. Ischemia is followed by accumulation of glutamate and aspartate in the extracellular fluid, causing cell death, which is aggravated by lack of oxygen and glucose.
Allergy medications may cause brain damage, increase dementia risk because of course they can, everything can. Alex Lasker. Updated July 14, 2016 at 7:50 PM.
“Therefore, the slow oscillation in norepinephrine concentration drives a slow fluctuation in the diameter of the arteries and in the blood volume in the brain.” ”This dynamic change in ...
