Annotation	Some recent studies have suggested that oestrogen replacement therapy improves cognition in healthy pre- and post-menopausal women. This study tested the hypothesis that bone mineral density (BMD), a marker of cumulative oestrogen exposure, is associated with cognitive function in non-demented older adults. A total of 8333 older community-dwelling women participated in the study. Compared with women with higher bone mineral density, women with low baseline BMD had up to 8% worse baseline cognitive scores and up to 6% worse repeat cognitive scores, even after multivariate adjustments. Women with vertebral fractures had lower cognitive test scores and a greater odds of cognitive deterioration than those without fractures. The findings indicate that women with osteoporosis have poorer cognitive function and a greater risk of cognitive deterioration. (AKM).
