Abstract

Objective The present study examined prospectively the relationship between memory of the traumatic event and subsequent development of posttraumatic stress disorder (PTSD). More specifically, the aims of this study were to 1) investigate the possibility that lack of memory of the traumatic event might be a protective factor; 2) assess whether memory of the traumatic event equally affects the three symptom clusters of PTSD: reexperiencing, avoidance, and hyperarousal; and 3) explore the predictive value of memory of the traumatic event for the development of subsequent PTSD in the immediate aftermath of the event. Method One hundred twenty subjects with mild traumatic brain injury who were hospitalized for observation were assessed immediately after the trauma and followed up 1 week, 3 months, and 6 months later. All participants underwent psychiatric evaluation and self-assessment of their memory of the traumatic event. Results Overall, 17 (14%) of the participants met full criteria for PTSD at 6 months. Subjects with memory of the traumatic event were significantly more likely to develop PTSD than those without memory of the traumatic event; the difference between the groups resulted primarily from the reexperiencing cluster. Logistic regression analysis revealed that memory of the traumatic event within the first 24 hours is a strong predictor of PTSD 6 months after the event. Conclusions Our study indicated that memory of a traumatic event is a strong predictor and a pote…

  • Subsequent TBI studies concurred that trauma memory impairment does not prevent PTSD but is associated with fewer re-experiencing symptoms.

    “Subsequent TBI studies specifically assessing trauma memory impairment concurred that it does not prevent PTSD but is associated with fewer re-experiencing symptoms of PTSD (Bryant et al., 2009; Cnossen et al., 2017; Gil, Caspi, Ben-Ari, Koren, & Klein, 2005).”

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.
