Alcohol consumption and incident dementia in older Japanese adults

A study evaluated the association between the amount and frequency of alcohol consumption and incident dementia in 53,311 older Japanese adults over a long follow-up period. A health checkup questionnaire was used to assess the amount and frequency of alcohol consumption.

The authors conclude that occasional or daily moderate drinking of alcoholic beverages (≤ 2 units per day), could reduce the risk of incident dementia compared to non-drinkers, with greater benefit for men with this level of daily consumption.
