Our analyses adjusted for multiple testing accounting for multiplicity of exposures. Finally, residual confounding and selection bias could explain some positive findings and low power may underlie some negative findings. In conclusion, associations of caffeine and alcohol intake and nutrient adequacy with longitudinal cognitive performance are mixed in this sample of older adults. Consistent with prior studies, potential beneficial effects were found for some measures, but not others, with moderation by baseline age and sex. Although findings for alcohol consumption were mixed, the findings were generally supportive of the idea that a high-quality diet and higher caffeine intake may benefit cognition acutely and even prevent age-related Quinagolide (hydrochloride) chemical information declines in certain cognitive domains, including global cognition, verbal memory, and attention. Further longitudinal studies conducted on larger samples of adults are needed to determine whether dietary factors individually or in combination are modifiers of cognitive trajectories among adults.
