Abstract

Traumatic brain injury (TBI) is a prominent risk factor for dementias including tauopathies like chronic traumatic encephalopathy (CTE). The mechanisms that promote prion-like spreading of Tau aggregates after TBI are not fully understood, in part due to lack of tractable animal models. Here, we test the putative role of seizures in promoting the spread of tauopathy. We introduce ‘tauopathy reporter’ zebrafish expressing a genetically encoded fluorescent Tau biosensor that reliably reports accumulation of human Tau species when seeded via intraventricular brain injections. Subjecting zebrafish larvae to a novel TBI paradigm produced various TBI features including cell death, post–traumatic seizures, and Tau inclusions. Bath application of dynamin inhibitors or anticonvulsant drugs rescued TBI-induced tauopathy and cell death. These data suggest a role for seizure activity in the prion-like seeding and spreading of tauopathy following TBI. Further work is warranted regarding anti-convulsants that dampen post-traumatic seizures as a route to moderating subsequent tauopathy.

  • Tau aggregation following traumatic brain injury administration was prevented by the anti-convulsant ezogabine and exacerbated by kainate treatment, demonstrating a role of seizure activity in mediating tauopathy development.

    “Furthermore, tau aggregation following TBI administration was prevented by the anti-convulsant ezogabine and exacerbated by kainate treatment, demonstrating a role of seizure activity in mediating tauopathy development (Alyenbaawi et al., 2021).”

    From Tauopathy and Epilepsy Comorbidities and Underlying Mechanisms (2022) · cites this paper as Alyenbaawi et al., 2021

    In Results, “Post-traumatic seizure intensity influences tauopathy progression” (page unavailable), the paper reports that retigabine significantly reduced tau aggregates after TBI, with many—but not all—treated zebrafish larvae developing no aggregates. Kainate increased tauopathy fourfold, and the authors attribute the drugs’ opposing effects largely to their modulation of post-traumatic seizures. The claim overstates the retigabine finding as complete prevention; our copy also calls the drug retigabine, not ezogabine. (LLM, conf=0.87)

  • Animal models reveal increased p-tau levels in the brain associated with traumatic brain injury-induced epileptic activity.

    “and animal models reveal increased p-tau levels in the brain associated with TBI-induced epileptic activity (Cho et al., 2020; Alyenbaawi et al., 2021).”

    From Tauopathy and Epilepsy Comorbidities and Underlying Mechanisms (2022) · cites this paper as Alyenbaawi et al., 2021

    The Results (‘Post-traumatic seizure intensity influences tauopathy progression’; page unavailable) report more tau aggregates in TBI-treated zebrafish larvae that displayed seizure-like behavior, supporting the association. But this paper measures Tau aggregates, not increased phosphorylated tau (p-tau) levels; its Discussion mentions p-tau expression only when describing a separate epilepsy study. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Tau aggregation positively correlated with traumatic brain injury severity and the presence of seizure-like clonic shaking in a transgenic zebrafish model.

    “Tau aggregation positively correlated with TBI severity and the presence of seizure-like clonic shaking.”

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.
