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 ...
Binge drinking, or heavy episodic drinking, can lead to damage in the limbic system that occurs after a relatively short period of time. This brain damage increases the risk of alcohol-related dementia, and abnormalities in mood and cognitive abilities. Binge drinkers also have an increased risk of developing chronic alcoholism.

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 .
This “can help optimize blood flow to the brain,” he says. Stay on top of your vision Research has found that untreated vision loss increases the risk of dementia by about 50 percent, so go to ...
"For binge-drinkers, it's a little bit worse because their brain gets sensitized to alcohol: When they drink, their brain is happy, but when they stop drinking for a period of time, the brain ...
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 ...
Alcohol intoxication affects the brain, causing slurred speech, clumsiness, and delayed reflexes. There is an increased risk of developing an alcohol use disorder for teenagers while their brain is still developing. [2] Adolescents who drink have a higher probability of injury including death. [2]
