Abstract

In a recent preliminary study it was reported that a severe head injury resulted in the deposition of beta amyloid protein (beta AP) in the cortical ribbon of 30% of patients who survived for less than two weeks. Multiple cortical areas have now been examined from 152 patients (age range 8 weeks-81 years) after a severe head injury with a survival time of between four hours and 2.5 years. This series was compared with a group of 44 neurologically normal controls (age range 51 to 80 years). Immunostaining with an antibody to beta AP confirmed the original findings that 30% of cases of head injury have beta AP deposits in one or more cortical areas. Increasing age seemed to accentuate the extent of beta AP deposition and potential correlations with other pathological changes associated with head injury were also investigated. In addition, beta amyloid precursor protein (beta APP) immunoreactivity was increased in the perikarya of neurons in the vicinity of beta AP deposits. The data from this study support proposals that increased expression of beta APP is part of an acute phase response to neuronal injury in the human brain, that extensive overexpression of beta APP can lead to deposition of beta AP and the initiation of an Alzheimer disease-type process within days, and that head injury may be an important aetiological factor in Alzheimer's disease.

  • The rapid accumulation of Aβ after TBI is well documented in both humans and experimental animal models.

    “The rapid accumulation of Aβ after TBI is well documented in both humans and experimental animal models.12–17”

    From Controlled Cortical Impact Results in an Extensive Loss of Dendritic Spines that Is Not Mediated by Injury-Induced Amyloid-Beta Accumulation (2013) · cites this paper as [15]

    The Abstract reports Aβ deposits in 30% of patients after severe head injury and says deposition can occur within days. The animal studies discussed in the βAPP Immunoreactivity section concern increased amyloid precursor protein (APP), not rapid accumulation of Aβ itself. This paper therefore supports the human part of the claim but not the animal-model part. (LLM, conf=0.88)

  • Accumulation of APP and extracellular deposition of the 40- to 42-amino acid Aβ peptide in senile plaques has been identified in human brain tissue soon after severe TBI.

    “Third, accumulation of APP and extracellular deposition of the 40- to 42-amino acid Aβ peptide in senile plaques has been identified in human brain tissue soon after severe TBI (29, 30).”

    From The Inflammatory Continuum of Traumatic Brain Injury and Alzheimer’s Disease (2018) · cites this paper as [29]

    The Abstract reports Aβ deposits after severe head injury and increased APP immunoreactivity near those deposits. The βAPP immunoreactivity section distinguishes the early diffuse deposits from classical or senile plaques, which it says were restricted to the oldest cases. Our copy does not establish that the deposited peptide was specifically 40–42 amino acids long. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Clinical studies indicate that Aβ accumulates within hours after severe TBI and is spread throughout the cerebral cortex compared to age-matched controls.

    “Clinical studies indicate that Aβ accumulates within hours after severe TBI and is spread throughout the cerebral cortex compared to age-matched controls (29, 31).”

    From The Inflammatory Continuum of Traumatic Brain Injury and Alzheimer’s Disease (2018) · cites this paper as [29]

    The βAP immunoreactivity results report deposits in 30% of severe-head-injury cases, including some who survived less than 24 hours, and higher positivity than in age-matched controls. They do not show that deposits were spread throughout the cerebral cortex: a positive case could have deposits in just one cortical area, and the pattern varied between cases. The copy does not establish that the patients who survived only four hours had deposits. Page numbers were not supplied for these passages. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The co-occurrence of TBI and APP mutation in the clinical setting is rare, thereby restricting the results of many of these studies.

    “The co-occurrence of TBI and APP mutation in the clinical setting is rare (29) thereby restricting the results of many of these studies.”

    From The Inflammatory Continuum of Traumatic Brain Injury and Alzheimer’s Disease (2018) · cites this paper as [29]

    In the discussion (page not available in our copy), the paper describes two pedigrees in which a person with an APP gene mutation had a history of significant head injury. It does not establish that this co-occurrence is rare in clinical settings or say that its rarity restricts the results of other studies. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Rapid generation and deposition of Aβ in stroke and after head trauma could benefit maintenance of BBB integrity and inhibit leakage of serum components into the brain, leading to neuroinflammation.

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.
