狂犬病如何影响注意力和记忆

If you are 25 years or younger and you drink to excess even once a week, your brain may exhibit some deficits as a result of your binge drinking. Your ability to pay attention and use your visual工作记忆可能会受到损害, according to researchers.

喝到烂醉被定义为饮用5种或更多标准的酒精饮料，为2小时内为雌性为雌性进行四个或更多。在美国，高达45％的大学生每周至少举行一次狂欢饮酒或沉重的饮酒集。

Much of your brain develops early in life, but some regions of the brain continue to develop until age 25. Researchers say it is those very regions that are affected most by heavy episodic drinking.

Heavy Drinking Pattern Affects Brain

That intense pattern of drinking can cause more damage to your brain than consuming the same about of alcohol over a longer period. In fact, these heavy drinking episodes followed by "morning after"宿宿物研究人员表示，模仿通常在慢性酗酒者中观察到的模式，这些模式在滥用和排毒的循环中。

The regions of the brain that develop late may be the most vulnerable, according to Alberto Crego, a doctoral student at the University of Santiago de Compostela, Galicia, Spain.

Binge Drinkers, but Not Alcoholics

CREGO和他的同事是最新的科学家负面后果狂犬菌饮用。他们研究了95岁的西班牙大学生，年龄18至20岁。在95年，有42岁的人是狂欢饮酒者，53名“控制”的学生没有喝酒或者是轻饮用者。

All of the students in the study were considered otherwise healthy. In other words, none of the students were diagnosed with an alcohol-use disorder, alcohol dependence or any other alcohol-related disorders.

工作记忆的问题

The researchers used event-related electrophysiological brain response (ERP) technique to measure the students' brain response to a visual working memory task. The study found:

• Students who were binge drinkers displayed anomalies during execution of the task, even when they correctly executed the task.
• 狂欢饮用者在任务期间需要更好的注意处理来正确完成它。
• The binge drinking students had difficulties differentiating between relevant and irrelevant stimuli.
• 狂欢饮用学生在任务期间呈现的不同信息之间分发注意力和工作内存资源的效率较低。

Alterations in the Brain

The authors of the study concluded that healthy adolescents and young people who binge drink—even only once or twice a week, and who do not display chronic alcohol consumption or alcohol dependence, "may suffer alterations at the electrophysiological level in attentional and working memory processing."

The Spanish study is another in a long list of research that shows that binge-type drinking is harmful and can have long-term consequences. No matter which type of binge drinker you are, your health will benefit by changing your drinking pattern.

注意和记忆问题不是狂欢饮用者可以体验的唯一负面影响。有许多与狂欢饮酒相关的其他健康问题，包括代谢危险因素，决策受损，口头学习问题等组群。
