Binge drinking effects on the brain

Binge drinking effects on the brain, Binge drinking affects brain memory, That old joke about going out drinking to kill a few brain cells may not be so funny any more.

Young people who binge drink could be risking serious damage to their brains now and increasing memory loss later in adulthood, according to new research. Adolescents may be even more vulnerable to brain damage from excessive drinking than older drinkers. Binge drinking or heavy episodic drinking is the modern epithet for drinking alcoholic beverages with the primary intention of becoming intoxicated by heavy consumption of alcohol over a short period of time. It is a kind of purposeful drinking style that is popular in several countries worldwide, and overlaps somewhat with social drinking since it is often done in groups. The degree of intoxication, however, varies between and within various cultures that engage in this practice. A binge on alcohol can occur over hours or last up to several days. Due to the long-term effects of alcohol misuse, binge drinking is considered to be a major public health issue.


Binge drinking is associated with a profound social harm, economic costs as well as increased disease burden. Binge drinking is more common in males, during adolescence and young adulthood. Most binge drinkers are not familiar with the risks associated with binge drinking. Heavy regular binge drinking is associated with adverse effects on neurologic, cardiac, gastrointestinal, hematologic, immune, musculoskeletal organ systems as well as increasing the risk of alcohol induced psychiatric disorders. A US-based review of the literature found that up to one third of adolescents binge drink, with six percent reaching the threshold of having an alcohol related substance use disorder. Approximately one in twenty five women binge drink during pregnancy, which can lead to fetal alcohol syndrome and fetal alcohol spectrum disorders. Binge drinking during adolescence is associated with traffic accidents and other types of accidents, violent behavior as well as suicide. The more often a child or adolescent binge drinks and the younger they are the more likely that they will develop an alcohol use disorder including alcoholism. A large number of adolescents who binge drink also consume other psychotropic substances.

Binge drinking has the propensity to result in brain damage faster as well as more severely than chronic 'non stop' drinking (alcoholism), due to the neurotoxic effects of the repeated rebound withdrawal effects. The tolerance that occurs during chronic ('non-stop') drinking delays alcohol related brain damage compared to binge drinking which induces immediate and repeated insults to the brain. The neurotoxic insults to the brain are due to very large amounts of glutamate being released on a repeated basis which over-stimulates the brain after each binge finishes, resulting in excitotoxicity. The developing adolescent brain is thought to be particularly susceptible to the neurotoxic effects of binge drinking, with some evidence of brain damage occurring from drinking more than 4 or 5 drinks once or twice per month.
