More evidence moderate alcohol consumption helps stave off dementia

April, 2011

More evidence that a moderate amount of alcohol helps protect against Alzheimer’s —but not vascular dementia or age-related cognitive decline.

A review of 23 longitudinal studies of older adults (65+) has found that small amounts of alcohol were associated with lower incidence rates of overall dementia and Alzheimer dementia, but not of vascular dementia or age-related cognitive decline. A three-year German study involving 3,327 adults aged 75+ extends the evidence to the older-old.

The study found alcohol consumption was significantly associated with 3 other factors that helped protect against dementia: better education, not living alone, and absence of depression. Nevertheless, the lower risk remained after accounting for these factors.

The ‘magic’ amount of alcohol was between 20-29g, roughly 2-3 drinks a day. As in other studies, a U-shaped effect was found, with higher risk found among both those who consumed less than this amount of alcohol, and those who consumed more.
