N2 - The growing body of evidence indicates that habitual coffee consumption has beneficial effects on brain functions in older adults, but its effects on different aspects of cognitive function are relatively unknown. We analyzed data of 104 elderly men and women to investigate the effects of habitual coffee consumption on attention and memory with respect to participants’ professional intellectual workload (scientists vs. people not engaged in professional scientific activity) and sex.
