Hyperammonemia, or high ammonia levels, is a metabolic disturbance characterised by an excess of ammonia in the blood. Severe hyperammonemia is a dangerous condition that may lead to brain injury and death. It may be primary or secondary. Ammonia is a substance that contains nitrogen. It is a product of the catabolism of protein.
This ammonia will obviously have to be transported out of the neurons and back into the astrocytes for detoxification, as an elevated ammonia concentration has detrimental effects on a number of cellular functions and can cause a spectrum of neuropsychiatric and neurological symptoms (impaired memory, shortened attention span, sleep-wake ...
The resultant effect of this toxicity can be reduced brain energy metabolism and function. Importantly, the toxic effects of ammonia on astrocyte remodeling can be reduced through administration of L-carnitine. [89] This astrocyte remodeling appears to be mediated through ammonia-induced mitochondrial permeability transition.
GS is present predominantly in the brain, kidneys, and liver. [4] [10] GS in the brain participates in the metabolic regulation of glutamate, the detoxification of brain ammonia, the assimilation of ammonia, recyclization of neurotransmitters, and termination of neurotransmitter signals. [4] [14] GS, in the brain, is found primarily in ...
A recent study by the University of Southern California revealed that exposure to air pollution can harm children's learning and memory, the LA Post reports.. Ammonium nitrate, a specific ...
[2] [6] It may be supported by blood ammonia levels, an electroencephalogram, or computer tomography (CT scan) of the brain. [4] [6] Hepatic encephalopathy is possibly reversible with treatment. [1] This typically involves supportive care and addressing the triggers of the event. [4] Lactulose is frequently used to decrease ammonia levels. [1]
Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine.Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury.
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
