Abstract

While a history of a single traumatic brain injury (TBI) is associated with the later development of syndromes of cognitive impairment such as Alzheimer's disease, the long-term pathology evolving after single TBI is poorly understood. However, a progressive tauopathy, chronic traumatic encephalopathy, is described in selected cohorts with a history of repetitive concussive/mild head injury. Here, post-mortem brains from long-term survivors of just a single TBI (1-47 years survival; n=39) vs. uninjured, age-matched controls (n=47) were examined for neurofibrillary tangles (NFTs) and amyloid-β (Aβ) plaques using immunohistochemistry and thioflavine-S staining. Detailed maps of findings permitted classification of pathology using semiquantitative scoring systems. NFTs were exceptionally rare in young, uninjured controls, yet were abundant and widely distributed in approximately one-third of TBI cases. In addition, Aβ-plaques were found in a greater density following TBI vs. controls. Moreover, thioflavine-S staining revealed that while all plaque-positive control cases displayed predominantly diffuse plaques, 64% of plaque-positive TBI cases displayed predominantly thioflavine-S-positive plaques or a mixed thioflavine-S-positive/diffuse pattern. These data demonstrate that widespread NFT and Aβ plaque pathologies are present in up to a third of patients following survival of a year or more from a single TBI. This suggests that a single TBI induces long-term neuropathological changes akin to those found in neurodegenerative disease.

  • Sustaining even a single traumatic brain injury can result in progressive neurofibrillary tangle formation that is more extensive and severe than what is expected with normal aging.

    “For instance, sustaining even a single TBI can result in progressive NFT formation that is more extensive and severe than what is expected with normal aging (Johnson et al., 2012; Zanier et al., 2018).”

    From Tauopathy and Epilepsy Comorbidities and Underlying Mechanisms (2022) · cites this paper as Johnson et al., 2012

  • Other studies indicate that neuroinflammation, b-amyloid deposition, and accumulation of TDP-43 and p-tau can arise following a single moderate-severe TBI, and there is emerging evidence that multiple types of neuropathology can be present following repetitive mild TBI.

    “There are other studies, however, indicating that different types of neuropathology, such as neuroinflammation (36), b-amyloid deposition (37), and accumulation of TDP-43 (38) and p-tau (37, 39, 40) can and do arise following a single moderate-severe TBI (41)(42)(43), and there is emerging evidence that multiple types of neuropathology can be present following repetitive mild TBI (43,44).”

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.
