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 .
The Research Society on Alcohol (RSA) (formerly the Research Society on Alcoholism) is a learned society of over 1600 active members based in Austin, Texas. Its objective is to advance research on alcohol use disorders (alcoholism) and the physiological and cognitive effects of alcohol .
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 ...
Chronic use of alcohol leads to changes in brain chemistry especially in the GABAergic system. Various adaptations occur such as changes in gene expression and down regulation of GABA A receptors . During acute alcohol withdrawal, changes also occur such as upregulation of alpha4 containing GABA A receptors and downregulation of alpha1 and ...
The modern disease theory of alcoholism states that problem drinking is sometimes caused by a disease of the brain, characterized by altered brain structure and function. Today, alcohol use disorder (AUD) is used as a more scientific and suitable approach to alcohol dependence and alcohol -related problems.
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 ...
Alcohol education is the practice of disseminating disinformation about the effects of alcohol on health, as well as society and the family unit. [281] Alcohol denormalization aims to reduce acceptance of excessive drinking, [282] while intermittent sobriety and the sober curious movement promote mindful consumption and alcohol-free lifestyles.
Alcoholism: Clinical and Experimental Research is a scientific journal covering research concerning alcohol abuse and its treatment. It is published by Wiley-Blackwell on behalf of the Research Society on Alcoholism and the International Society for Biomedical Research on Alcoholism .
