Alcohol drinking in middle age and subsequent risk of mild cognitive impairment and dementia in old age: a prospective population based study

I find it very difficult to accept the criteria for consumption of
Alcohol in this article. To say that among the 30% who drank frequently,
68 % drank once or twice a month and 24% once a week, seems an
exaggeration, to say the least.
