Second Study

1. 5,054 men and 2,099 women's drinking habits were assessed three times over 10 years. 

    -A drink was considered wine, beer or liquor.    

2. Then, when the participants were an average age of 56, they took their first memory and executive function test. 

3.The tests were repeated twice over the next 10 years.

Results:

Heavy drinkers showed memory and executive function declines 1.5-6 years quicker than those who had fewer drinks per day.

*However, there were no differences in memory and executive function decline between men who did not drink and those who were light or moderate drinkers (drinking less than 20 grams, or two US drinks per day).
