A 2011 study from Loyola University looked at research dating back as far as 1977 and found that moderate drinking didn't impair cognition in young people. It also found these moderate drinkers were 23 percent less likely to develop dementia, Alzheimer's disease, and other kinds of cognitive impairment as they aged. A smaller result from the same study suggested that wine was more protective than other alcohols. However, Robinson says people need to be aware that too much drinking can cause cognitive problems, such as alcohol-related dementia.
