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.
Hypomania (literally "under mania " or "less than mania") [3] is a mental and behavioral disorder, [4] characterised essentially by an apparently non-contextual elevation of mood (euphoria) that contributes to persistently disinhibited behavior. The individual with the condition may experience irritability, not necessarily less severe than full ...
Americans’ relationship with alcohol and their perception of how healthy it is may be changing — with younger people drinking a lot less, and many people in general reevaluating whether even ...
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 ...
The brain regions most sensitive to harm from binge drinking are the amygdala and prefrontal cortex. [28] People in adolescence who experience repeated withdrawals from binge drinking show impairments of long-term nonverbal memory. Alcoholics who have had two or more alcohol withdrawals show more frontal lobe cognitive dysfunction than those ...
Long-term, stable consequences of chronic hazardous alcohol use are thought to be due to stable alterations of gene expression resulting from epigenetic changes within particular regions of the brain. [26][27][28] For example, in rats exposed to alcohol for up to 5 days, there was an increase in histone 3 lysine 9 acetylation in the ...
The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol, so once it is in ...
Stolle, Sack and Thomasius define binge drinking as episodic excessive drinking. [7] There is currently no worldwide consensus on how many drinks constitute a "binge", but in the United States, the term has been described in academic research to mean consuming five or more standard drinks (male), or four or more drinks (female), [12] over a two-hour period.
