I found it very odd that their study basically says that people who currently drink 7-14 drinks per week have the lowest chance of dementia even lower than the “never drinkers”. While I somewhat understand that those who are heavy drinkers (>40 drinks per week) would have a greater dementia risk, and that current low/no drinkers may have been heavy drinkers in the past so would also increase their risk, how does the 7-14 DPW group having a much lower risk than the “never drinkers” in this study make sense given what they’re trying to say here? If any amount of alcohol intake increases risk then all the cohorts should carry a higher risk then the never drinker group but it does not.
