摘要：

Objective Women have a higher lifetime risk of Alzheimer's disease (AD) than men. Among cognitively normal (CN) older adults, women exhibit elevated tau positron emission tomography (PET) signal compared with men. We explored whether menopause exacerbates sex differences in tau deposition in middle-aged adults. Methods 328 CN participants from the Framingham Study (mean age = 57 years (+/- 10 years), 161 women, of whom, 104 were post-menopausal) underwent tau and beta-amyloid (A beta)-PET neuroimaging. We examined global A beta-PET, and tau-PET signal in 5 regions identified a priori as demonstrating significant sex differences in older adults (in temporal, inferior parietal, middle frontal, and lateral occipital regions). We examined sex and menopause status-related differences in each region-of-interest, using linear regressions, as well as interactions with A beta and APOE epsilon 4 genotype. Results Women exhibited higher tau-PET signal (p < 0.002), and global A beta-PET (p = 0.010), than men in inferior parietal, rostral middle frontal, and lateral occipital regions. Compared with age-matched men, post-menopausal women showed significantly higher tau-PET signal in parieto-occipital regions (p < 0.0001). By contrast, no differences in tau-PET signal existed between pre-menopausal women and men. A beta-PET was not associated with menopausal status or age. Neither A beta-PET nor APOE epsilon 4 status moderated sex or menopause associations with tau-PET. Interpretation Clear divergence in tauopathy between the sexes are apparent approximately 20 years earlier than previously reported. Menopause status moderated sex differences in A beta and tau-PET burden, with tau first appearing post-menopause. Sex and menopause differences consistently appeared in middle frontal and parieto-occipital regions but were not moderated by A beta burden or APOE epsilon 4, suggesting that menopause-related tau vulnerability may be independent of AD-related pathways.
