Abstract

OBJECTIVE: We evaluated the contribution of blast-pressure severity to cognitive functioning beyond posttraumatic stress disorder (PTSD) severity and traumatic brain injury (TBI). METHOD: = 254, 86.22% male) completed the Wechsler Adult Intelligence Scale (WAIS-IV) and Trail Making Test (TMT). The Clinician-Administered PTSD Scale (CAPS-5), Mid-Atlantic MIRECC Assessment of TBI, and the Salisbury Blast Interview evaluated PTSD diagnosis/severity, deployment TBI history/severity, and blast-exposure history/severity, respectively. RESULTS: = -2.01). CONCLUSION: Blast-pressure severity exacerbated the effects of mild TBI on a simple attention task, such that participants with TBI had gradual decrements in attention as blast severity increased. Veterans who incur a TBI and are exposed to blasts during deployment may experience persisting difficulties with cognitive functioning as a result of alterations in basic attention abilities.

  • Blast-related mTBI may have more enduring long-term effects on cognition compared to blunt mTBI, but the evidence is mixed.

    “Another factor specific to military populations with mixed research evidence is the concern that blast-related mTBI has more enduring long-term effects on cognition compared to blunt mTBI”

    From Can mild traumatic brain injury alter cognition chronically? A LIMBIC-CENC multicenter study. (2023) · cites this paper as Martindale et al., 2020

    The Discussion (page not available in our copy) says findings on blast-related versus non-blast mTBI are mixed: some studies find no cognitive difference, while others find subtle differences associated with blast exposure. The paper also raises the possibility of persisting cognitive difficulties, but it does not establish that effects of blast-related mTBI last longer than those of blunt mTBI. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • Extant literature has demonstrated inconsistent findings on the enduring deleterious effects of blast-related mTBI versus blunt mTBI including on cognition.

    “This is important because extant literature has demonstrated inconsistent findings on the enduring deleterious effects of blast-related mTBI versus blunt mTBI including on cognition (Belanger et al., 2009; Martindale et al., 2020).”

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.
