Abstract

OBJECTIVE: To assess whether family history (FH) of Alzheimer disease (AD) alone influences AD biomarker abnormalities. DESIGN: Adult Children Study. SETTING: Washington University's Charles F. and Joanne Knight Alzheimer's Disease Research Center. PARTICIPANTS: A total of 269 cognitively normal middle- to older-aged individuals with and without an FH for AD. MAIN OUTCOME MEASURES: Clinical and cognitive measures, magnetic resonance imaging-based brain volumes, diffusion tensor imaging-based white matter microstructure, cerebrospinal fluid biomarkers, and molecular imaging of cerebral fibrillar amyloid with positron emission tomography using the [(11)C] benzothiazole tracer, Pittsburgh compound B. RESULTS: A positive FH for AD was associated with an age-related decrease of cerebrospinal fluid Aβ42; the ε4 allele of apolipoprotein E (APOE4) did not alter this effect. Age-adjusted cerebrospinal fluid Aβ42 was decreased for individuals with APOE4 compared with the level for those without, and the decrease was larger for individuals with a positive FH compared with the decrease for those without. The variation of cerebrospinal fluid tau and Pittsburgh compound B mean cortical binding potential increased by age. For individuals younger than 55, an age-related increase in mean cortical binding potential was associated with APOE4 but not FH. For individuals older than 55, a positive FH and a positive APOE4 implied the fastest age-related increase in mean cortical binding potential. A positive FH was associated with decreased fractional anisotropy from diffusion tensor imaging in the genu and splenium of the corpus callosum. CONCLUSION: Independent of APOE4, FH is associated with age-related change of several cerebrospinal fluid, Pittsburgh compound B, and diffusion tensor imaging biomarkers in cognitively normal middle- to older-aged individuals, suggesting that non- APOE susceptibility genes for AD influence AD biomarkers.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The APOE ε4 allele has been linked to increased risk for Alzheimer's disease while the ε2 allele may provide protection from Alzheimer's disease.

    “The APOE ε 4 allele of apolipoprotein E gene (APOE ε 4) has been linked to increased risk for Alzheimer's disease 19 while the ε 2 allele (APOE ε 2) may provide protection from Alzheimer's disease 20,21 .”

    From OASIS-3: Longitudinal Neuroimaging, Clinical, and Cognitive Dataset for Normal Aging and Alzheimer Disease (2019) · cites this paper as [19]

    The Methods (Statistical Analysis; page unavailable) treat APOE ε4 as a risk factor, and the Results associate it with Alzheimer-related biomarker abnormalities. The paper does not address whether APOE ε2 protects against Alzheimer's disease, so that part of the claim is unsupported. (LLM, conf=0.85)

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.
