Abstract

Traumatic brain injury (TBI) due to explosive blast exposure is a leading combat casualty. It is also implicated as a key contributor to war related mental health diseases. A clinically important consequence of all types of TBI is a high risk for development of seizures and epilepsy. Seizures have been reported in patients who have suffered blast injuries in the Global War on Terror but the exact prevalence is unknown. The occurrence of seizures supports the contention that explosive blast leads to both cellular and structural brain pathology. Unfortunately, the exact mechanism by which explosions cause brain injury is unclear, which complicates development of meaningful therapies and mitigation strategies. To help improve understanding, detailed neuropathological analysis is needed. For this, histopathological techniques are extremely valuable and indispensable. In the following we will review the pathological results, including those from immunohistochemical and special staining approaches, from recent preclinical explosive blast studies.

  • It is estimated that over 50% of severe traumatic brain injury cases will result in seizures or post-traumatic epilepsy.

    “Furthermore, it is estimated that over 50% of severe TBI cases will result in seizures or PTE (Kovacs et al., 2014), 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 Kovacs et al., 2014

    The Introduction estimates that over 50% of patients with penetrating TBI will develop post-traumatic epilepsy, and says seizure risk rises with TBI severity. It does not give that estimate for severe TBI cases generally; its over-50% figure is specific to penetrating injury. (LLM, conf=0.88)

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.
