A new study found binge drinking affects attention and working memory in young university students.
Researchers defined binge drinkers as men who drink at least five drinks in a sitting, and women who have four or more.
Researchers found among about 100 students, those who binge have more problems completing tasks that require memory.
They also need to provide more attention to get that task done.
In a separate study -- researchers found excessive drinking can also damage brain regions used for processing facial emotions.
Both studies appear in the journal "Alcoholism: Clinical and Experimental Research."
