  2. Long-term impact of alcohol on the brain - Wikipedia

    The long-term impact of alcohol on the brain has become a growing area of research focus. While researchers have found that moderate alcohol consumption in older adults is associated with better cognition and well-being than abstinence, [ 1 ] excessive alcohol consumption is associated with widespread and significant brain lesions .

  3. Alcohol-related brain damage - Wikipedia

    en.wikipedia.org/wiki/Alcohol-related_brain_damage

    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 ...

    Another one of alcohol's agreeable effects is body relaxation, which is possibly caused by neurons transmitting electrical signals in an alpha waves-pattern; such waves are actually observed (with the aid of EEGs) whenever the body is relaxed. [citation needed] Short-term effects of alcohol include the risk of injuries, violence, and fetal ...

    en.wikipedia.org/wiki/Long-term_effects_of_alcohol

    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 ...

    Short-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain, with increased risk of several types of cancer and alcohol use disorder. [1] Alcohol intoxication affects the brain, causing slurred speech, clumsiness, and delayed reflexes.

  7. Effects of alcohol on memory - Wikipedia

    en.wikipedia.org/wiki/Effects_of_alcohol_on_memory

    Alcohol acts as a general central nervous system depressant, but it also affects some specific areas of the brain to a greater extent than others. Memory impairment caused by alcohol has been linked to the disruption of hippocampal function—particularly affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation ...

  8. Pharmacology of ethanol - Wikipedia

    en.wikipedia.org/wiki/Pharmacology_of_ethanol

    The reinforcing effects of alcohol consumption are mediated by acetaldehyde generated by catalase and other oxidizing enzymes such as cytochrome P-4502E1 in the brain. [60] Although acetaldehyde has been associated with some of the adverse and toxic effects of ethanol, it appears to play a central role in the activation of the mesolimbic ...

  9. Alcohol-related dementia - Wikipedia

    en.wikipedia.org/wiki/Alcohol-related_dementia

    Korsakoff's syndrome and Wernicke–Korsakoff syndrome are particular forms of alcohol related brain injury which may be related to alcohol related dementia. [18] Many experts use the terms alcohol (or alcoholic) dementia to describe a specific form of ARD, characterized by impaired executive function (planning, thinking, and judgment). [5]
