Abstract

Background: Gender‐specific risks for dementia and Alzheimer's disease (AD) starting in midlife remain largely unknown. Methods: Prospectively ascertained dementia/AD and cause‐specific mortality in Framingham Heart Study (FHS) participants was used to generate 10‐ to 50‐year risk estimates of dementia/AD on the basis of the Kaplan–Meier method (cumulative incidence) or accounting for competing risk of death (lifetime risk [LTR]). Results: Overall, 777 cases of incident dementia (601 AD) occurred in 7901 participants (4333 women) over 136,266 person‐years. Whereas cumulative incidences were similar in women and men, LTRs were higher in women older than 85 years of age. LTR of dementia/AD at age 45 was 1 in 5 in women and 1 in 10 in men. Cardiovascular mortality was higher in men with rate ratios decreasing from approximately 6 at 45 to 54 years of age to less than 2 after age 65. Conclusion: Selective survival of men with a healthier cardiovascular risk profile and hence lower propensity to dementia might partly explain the higher LTR of dementia/AD in women.

  • Lifetime risk for Alzheimer's dementia for both sexes was slightly higher at age 65 than at age 45.

    “The risks for both sexes were slightly higher at age 65. 261”

    From 2023 Alzheimer's disease facts and figures (2023) · cites this paper as [261]

    Results §4.2 reports lifetime risk of Alzheimer’s dementia at age 45 for women and men and says that the same trends applied when observation began at age 65. The passages available from our copy do not give the age-65 estimates or establish that they were slightly higher for both sexes than the age-45 estimates (page not provided). (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • Women live longer than men on average, and older age is the greatest risk factor for Alzheimer's.

    “Women live longer than men on average, and older age is the greatest risk factor for Alzheimer's.”

    From 2024 Alzheimer's disease facts and figures (2024) · cites this paper as [286]

    The Discussion says women have longer life expectancy, and the Background and Results report that AD risk increases with age. The paper does not establish that older age is the greatest risk factor for AD relative to other factors. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Women have a greater prevalence of Alzheimer disease than men, at least partly because women live longer.

    “It is known that women have a greater prevalence of Alzheimer disease (AD) than men, at least partly because women live longer.1,2,3”

    From Sex differences in cognitive decline among US adults (2021) · cites this paper as [2]

    The Results (§4.2; page unavailable) report a higher lifetime risk of AD in women than men. The Discussion (§5; page unavailable) suggests that women’s longer life expectancy partly explains that difference, alongside selective survival among men. The paper does not establish the claimed difference in AD prevalence specifically; its prevalence statement concerns dementia in the oldest-old. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The lifetime risk for Alzheimer's dementia at age 45 was approximately 1 in 5 (20%) for women and 1 in 10 (10%) for men.

    “As shown in Figure 4, the study estimated that the lifetime risk for Alzheimer's dementia at age 45 was approximately 1 in 5 (20%) for women and 1 in 10 (10%) for men.”

    From 2024 Alzheimer's disease facts and figures (2024) · cites this paper as [286]

  • The lifetime risk for developing Alzheimer's disease is two times higher in women than in men.

    “The lifetime risk for developing AD is two times higher in women than men [3].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
