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 ...
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.”
A simple test for intellectual function, like the Folstein mini–mental state examination, is the minimum screen for dementia. The test requires 15–20 minutes to administer and is available in mental health centers. [8] Diagnosing alcohol-related dementia can be difficult due to the wide range of symptoms and a lack of specific brain ...
These adverse effects are believed to be due to the neurotoxic effects of repeated withdrawal from alcohol on aberrant neuronal plasticity and cortical damage. Repeated periods of acute intoxication followed by acute detoxification has profound effects on the brain and is associated with an increased risk of seizures as well as cognitive deficits.
Alcohol education is the practice of disseminating information about the effects of alcohol on health, as well as society and the family unit. [71] It was introduced into the public schools by temperance organizations such as the Woman's Christian Temperance Union in the late 19th century. [ 71 ]
Ethanol has a variety of analogues, many of which have similar actions and effects. In chemistry, "alcohol" can encompass other mind-altering alcohols besides the kind we drink. Some examples include synthetic drugs like ethchlorvynol and methylpentynol, once used in medicine. Also, ethanol is colloquially referred to as "alcohol" because it is ...
