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.
PBA is most commonly observed in people with neurologic injuries such as traumatic brain injury (TBI) and stroke, [19] [21] and neurologic diseases such as dementias including Alzheimer's disease, attention deficit hyperactivity disorder (ADHD), [5] [22] multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), and Parkinson's disease (PD).
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 ...
Yawning has also been likened to “a hit of caffeine,” Sullivan adds. “So anytime that we’re kind of threatened by being under-stimulated or overstimulated, that [yawning] part of the brain ...
Brain injury (BI) is the destruction or degeneration of brain cells. Brain injuries occur due to a wide range of internal and external factors. ... Symptoms of a mild ...
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 ...
In a new study, researchers from the University of Nottingham looked at the brain to determine what makes yawning contagious. The BBC reports it happens in the part of the brain that controls ...
Reflex anoxic seizures are a particular type of anoxic seizure, most commonly seen in young children in whom an anoxic seizure or syncope is provoked or precipitated by a noxious stimulus (hence "reflex"). Various precipitants have been identified, but the most common is an unexpected bump to the head.
