Based on their alcohol consumption, participants were split into four groups: non-drinkers, mild drinkers (less than 15 grams (g) of alcohol a day, or about one drink), moderate drinkers (15 to 30g of alcohol), and heavy drinkers (more than 30g daily).
During the follow-up, the researchers detected 100,282 cases of various dementia types.
Interestingly, mild and moderate drinking were associated with a lower risk of the mind-robbing condition.
However, heavy drinking increased the risk of all-cause dementia instead.
