Abstract

Objective: Trauma‐exposed individuals with post‐traumatic stress disorder (PTSD) display reduced amygdala and hippocampal size and impaired cognition. However, studies on trauma‐exposed individuals with dissociative amnesia (DA) or dissociative identity disorder (DID) are lacking. Method: Twenty‐three young women who had experienced severe childhood sexual/physical abuse, diagnosed with DA/DID or PTSD, and 25 healthy control subjects were subjected to 3D structural magnetic resonance imaging of amygdala and hippocampus and a clinical and neuropsychological investigation. Results: Compared with controls, trauma‐exposed subjects with PTSD ( n = 10) displayed significantly reduced amygdala and hippocampal size and significantly impaired cognition. By contrast, trauma‐exposed subjects with DA or DID ( n = 13) displayed normal amygdala and hippocampal size and normal cognition. Conclusion: We report for the first time volumetric results in subjects with DA/DID without PTSD as comorbid diagnosis. Our results indicate preserved amygdala and hippocampal size and preserved cognition in subjects with these disorders.

  • In DID, reduced volumes in amygdala and hippocampus and parahippocampus were found, although discrepant findings of normal amygdala and hippocampal volumes compared to healthy controls were also reported.

    “In DID, reduced volumes in the amygdala and hippocampus [94, 95] and parahippocampus [95] were found, although discrepant findings of normal amygdala and hippocampal volumes compared to healthy controls were also reported [96].”

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.
