Older adults who consume alcohol moderately on a regular basis are more likely to live to the age of 85 without dementia or other cognitive impairments than non-drinkers, according to a University of California San Diego School of Medicine-led study.
. 
The findings are published in the August issue of the Journal of Alzheimer's Disease.

Previous studies have found a correlation between moderate alcohol intake and longevity. "This study is unique because we considered men and women's cognitive health at late age and found that alcohol consumption is not only associated with reduced mortality, but with greater chances of remaining cognitively healthy into older age," said senior author Linda McEvoy, PhD, an associate professor at UC San Diego School of Medicine.
