Abstract

BACKGROUND AND PURPOSE: Age and the apolipoprotein E ε4 allele are well-known risk factors for Alzheimer disease, but whether female sex is also a risk factor remains controversial. It is also unclear how these risk factors affect rates of structural brain and clinical decline across the spectrum of preclinical to clinical Alzheimer disease. Our objective is to estimate the effects of apolipoprotein E ε4 and sex on age-specific rates of morphometric and clinical decline in late-onset sporadic Alzheimer disease. MATERIALS AND METHODS: With the use of linear mixed-effects models, we examined the effect of age, apolipoprotein E ε4, and sex on longitudinal brain atrophy and clinical decline among cognitively normal older individuals and individuals with mild cognitive impairment and Alzheimer disease (total = 688). We also evaluated the relationship between these effects and CSF biomarkers of Alzheimer disease pathology. RESULTS: Apolipoprotein E ε4 significantly accelerated rates of decline, and women in all cohorts had higher rates of decline than men. The magnitude of the sex effect on rates of decline was as large as those of ε4, yet their relationship to measures of CSF biomarkers were weaker. CONCLUSIONS: These results indicate that in addition to apolipoprotein E ε4 status, diagnostic and therapeutic strategies should take into account the effect of female sex on the Alzheimer disease process.

  • After diagnosis, women progress faster with more rapid cognitive and functional declines.

    “After diagnosis, women also progress faster with more rapid cognitive and functional declines [3–8]”

    From Sex-specific DNA methylation differences in Alzheimer’s disease pathology (2021) · cites this paper as [6]

    The Results (Rates of Decline in MCI; page unavailable) report faster decline for women on CDR-SB and ADAS-Cog, supporting the claim for participants with MCI. But the Results (Rates of Decline in AD; page unavailable) report no significant sex effect on any cognitive measure in participants diagnosed with Alzheimer disease. The paper therefore does not support the unqualified claim of faster cognitive and functional decline after an AD diagnosis. (LLM, conf=0.88)

  • Sex is an important factor that contributes to clinical and biological heterogeneity in Alzheimer's disease.

    “Sex is an important factor that contributes to the clinical and biological heterogeneities in Alzheimer’s disease (AD)”
  • Women exhibit increased global Alzheimer's neuropathological burden and greater cognitive impairment compared to men.

    “However, despite their prolonged survival, even with Alzheimer’s disease [7–9], women exhibit increased global Alzheimer’s neuropathological burden and greater cognitive impairment [10–13].”

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.
