Abstract

Background The association between antecedent head injury and AD is inconsistent. Objective To examine the association between early adult head injury, as documented by military hospital records, and dementia in late life; and to evaluate the interaction between head injury and APOE epsilon4 as risk factors for dementia. Methods The study had a population-based prospective historical cohort design. It included men who were World War II Navy and Marine veterans, and were hospitalized during their military service with a diagnosis of either a nonpenetrating head injury or another unrelated condition. In 1996 to 1997, military medical records were abstracted to document the occurrence and details of closed head injury. The entire sample was then evaluated for dementia and AD using a multistage procedure. There were 548 veterans with head injury and 1228 without head injury who completed all assigned stages of the study. The authors estimated risk of dementia, specifically AD, using proportional hazards models. Results Both moderate head injury (hazard ratio [HR] = 2.32; CI = 1.04 to 5.17) and severe head injury (HR = 4.51; CI = 1.77 to 11.47) were associated with increased risk of AD. Results were similar for dementia in general. The results for mild head injury were inconclusive. When the authors stratified by the number of APOE epsilon4 alleles, they observed a nonsignificant trend toward a stronger association between AD and head injury in men with more epsilon4 alleles.

Claims other papers make about this one

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

  • Numerous population-based studies demonstrate that head injury during adulthood increases the risk of AD later in life.

    “First, numerous population-based studies demonstrate that head injury during adulthood increases the risk of AD later in life (12–19)”
  • Several studies have suggested that the association between Alzheimer's disease and head injury may be stronger in carriers of the APOE-4 allele.

    “several studies have suggested that this association may be stronger in carriers of the APOE-4 allele (30–32).”
  • Synergistic effects of head injury and APOE genotypes in AD were reported by some studies but not all.

    “Synergistic effects of head injury and APOE genotypes in AD were reported by some (30–32), but not all studies (53;54).”

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.
