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.
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 ...
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 ...
The closer a person drinks to sleep, the worse the effects. "Alcohol has a half-life of four to five hours, so if you drink at happy hour at, say, 6 p.m., that alcohol will stick with you until ...
Excessive alcohol intake, in particular, can adversely impact various aspects of your well-being, from your immediate safety to your long-term health. Excessive alcohol use can be categorized in ...
We’ve all seen the headlines: “6 Reasons Why a Little Glass of Wine Each Day May Do You Good,” or “Study Finds Drinking Wine with Meals Was Associated with Lower Risk of Type 2 Diabetes.”
The long-term effects of alcohol have been extensively researched. The health effects of long-term alcohol consumption vary depending on the amount consumed. Even light drinking poses health risks, [ 1 ] but atypically small amounts of alcohol may have health benefits. [ 2 ]
Epidemiological studies show an association between long-term alcohol intoxication and dementia. [5] Alcohol can damage the brain directly as a neurotoxin, [5] or it can damage it indirectly by causing malnutrition, primarily a loss of thiamine (vitamin B1). [2]
