Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
Excessive alcohol intake (binge drinking) causes a decrease in hippocampal neurogenesis, via decreases in neural stem cell proliferation and newborn cell survival. [19] [20] Alcohol decreases the number of cells in S-phase of the cell cycle, and may arrest cells in the G1 phase, thus inhibiting their proliferation. [19]
Excessive glutamate release is a known major cause of neuronal cell death. Glutamate causes neurotoxicity due to excitotoxicity and oxidative glutamate toxicity. Evidence from animal studies suggests that some people may be more genetically sensitive to the neurotoxic and brain damage associated with binge drinking regimes.
The level of ethanol consumption that minimizes the risk of disease, injury, and death is subject to some controversy. [16] Several studies have found a J-shaped relationship between alcohol consumption and health, [17] [18] [2] [19] meaning that risk is minimized at a certain (non-zero) consumption level, and drinking below or above this level increases risk, with the risk level of drinking a ...
Drugs which cause disulfiram-like reactions upon ingestion of alcohol as an unintended effect include: [6] [1] [7] Abacavir Cephalosporins , but only these with a methylthiotetrazole side chain or a methylthiodioxotriazine ring; thought to be due to common N -methylthiotetrazole metabolite , which is similar in structure to disulfiram.

Alcohol impairs episodic encoding, specifically for cued recall, recognition of completed word fragments, and free recall. [31] A blackout is an example of a difficulty in encoding episodic memories due to alcohol. Blackouts are caused by a rapid increase in blood alcohol concentration (BAC) which in turn distorts the neurons in the hippocampus ...
Dr. Clarke notes that mild liver damage usually starts with loss of appetite and fatigue, while more acute or severe liver damage has other symptoms. If you ever notice that you have jaundice, see ...
Consequently, LPS levels increase in the portal vein, liver and systemic circulation after alcohol intake. Immune cells in the liver respond to LPS with the production of reactive oxygen species, leukotrienes, chemokines and cytokines. These factors promote tissue inflammation and contribute to organ pathology.
