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.
In particular, the researchers found that among men and women 85 and older, individuals who consumed “moderate to heavy” amounts of alcohol five to seven days a week were twice as likely to be cognitively healthy than non-drinkers.
The researchers said the study does not suggest drinking is responsible for increased longevity and cognitive health. Alcohol consumption, particularly of wine, is associated with higher incomes and education levels, which in turn are associated with lower rates of smoking, lower rates of mental illness and better access to health care.
“This study shows that moderate drinking may be part of a healthy lifestyle to maintain cognitive fitness in aging,” said lead author Erin Richard, a graduate student in the Joint San Diego State University/UC San Diego Doctoral Program in Public Health.
