Abstract/Summary Background: Epidemiologic studies indicate that women are at higher risk for the development of AD compared to men. Clinical studies have not been verified by neuropathologic findings. Objective(s): We compared the extent of AD changes for men and women at age 25 and each decade of age thereafter to age 95. Methods: information on Braak staging for SP (none, A to C) and NFT (none, I to VI) was available for more than 5000 subjects ascertained at routine autopsy. About a third of the subjects had APOE genotype information. Linear models were constructed. Results: There was on average over all APOE genotypes (n > 5000) a 3-year acceleration of NFT staging for women. In more detail, men and women had the same likelihood for NFT at the initial predilection site in the transentorhinal cortex (I). But, women were more likely to reach stages II (entorhinal) and III (hippocampal) clearly evident at ages 65 (p = 0.01) and 75 (p = 0.01). Isocortical stages IV to VI were also more common for women. Looking at subjects who had APOE information, there was no gender gap for APOE2/3+ subjects. There was a large gender gap for APOE4+ subjects. In addition, women at early NFT stages I to IiI APOE4+ and in late middle age were much more likely to have extensive SP deposits throughout the brain compared to APOFA+ men. Conclusions: APOE4+ women had more brain regions containing NFT and SP compared to APOFA+ men of the same age from about age 55 years onward. The rapid increase in AD neuropathology in late middle age for a subgroup of women argues in favor of development of early interventional strategies to be selectively applied and for better genetic definition of the high-risk subgroup.
