Associations between alcohol consumption and cognitive function are discordant and data focusing on midlife exposure are scarce.


To estimate the association between midlife alcohol consumption and cognitive performance assessed 13 y later while accounting for comorbidities and diet.


3,088 French middle-aged adults included in the SU.VI.MAX 1994 study with available neuropsychological evaluation 13 y later. Data on alcohol consumption were obtained from repeated 24h dietary records collected in 1994–1996. Cognitive performance was assessed in 2007–2009 via a battery of 6 neuropsychological tests. A composite score was built as the mean of the standardized individual test scores mean = 50, SD = 10. ANCOVA were performed to estimate mean differences in cognitive performance and 95% confidence intervals CI.


In women, abstainers displayed lower cognitive scores than did low-to-moderate alcohol drinkers 1 to 2 drinks-day mean difference = −1.77; 95% CI: −3.29, −0.25. In men, heavy drinkers >3 drinks-day had higher cognitive scores than did low-to-moderate 1 to 3 drinks-day mean difference = 1.05; 95% CI: 0.10, 1.99. However, a lower composite cognitive score was detected in male drinkers consuming ≥90 g-d ≈8 drinks-d. A higher proportion of alcohol intake from beer was also associated with lower cognitive scores. These associations remained significant after adjustment for diet, comorbidities and sociodemographic factors.


In men, heavy but not extreme drinking was associated with higher global cognitive scores. Given the known harmful effects of alcohol even in low doses regarding risk of cancer, the study does not provide a basis for modifying current public health messages.
