Abstract

PET was used to evaluate the effect of estrogen use on regional cerebral glucose metabolism in postmenopausal women. Women receiving estrogen replacement therapy (ERT+), women not receiving estrogen (ERT-), and women with AD were studied. The ERT- group showed metabolic ratios that were intermediate to the ERT+ and AD groups, although they did not show any signs of cognitive impairment. These findings show an effect of estrogen depletion on brain metabolic activity.
