Abstract

Neuroanatomical evidence on the relationship between posttraumatic stress disorder (PTSD) and dissociative disorders is still lacking. We acquired brain structural magnetic resonance imaging (MRI) scans from 17 patients with dissociative identity disorder (DID) and co-morbid PTSD (DID-PTSD) and 16 patients with PTSD but without DID (PTSD-only), and 32 healthy controls (HC), and compared their whole-brain cortical and subcortical gray matter (GM) morphological measurements. Associations between GM measurements and severity of dissociative and depersonalization/derealization symptoms or lifetime traumatizing events were evaluated in the patient groups. DID-PTSD and PTSD-only patients, compared with HC, had similarly smaller cortical GM volumes of the whole brain and of frontal, temporal and insular cortices. DID-PTSD patients additionally showed smaller hippocampal and larger pallidum volumes relative to HC, and larger putamen and pallidum volumes relative to PTSD-only. Severity of lifetime traumatizing events and volume of the hippocampus were negatively correlated. Severity of dissociative and depersonalization/derealization symptoms correlated positively with volume of the putamen and pallidum, and negatively with volume of the inferior parietal cortex. Shared abnormal brain structures in DID-PTSD and PTSD-only, small hippocampal volume in DID-PTSD, more severe lifetime traumatizing events in DID-PTSD compared with PTSD-only, and negative correlations between lifetime traumatizing events and hippocampal volume suggest a trauma-related etiology for DID. Our results provide neurobiological evidence for the side-by-side nosological classification of PTSD and DID in the DSM-5.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Volumes of putamen and pallidum were negatively correlated with severity of derealization/depersonalization.

    “Volumes of these regions (implicated in motor control [103–105]) were negatively correlated with severity of derealization/depersonalization [103].”

    From Dissociation and Alterations in Brain Function and Structure: Implications for Borderline Personality Disorder (2017) · cites this paper as [103]

    Section 3.2.2 reports positive correlations between the dissociative-symptom component and bilateral putamen and right pallidum volumes; Table 4 gives positive coefficients for all three. The Discussion likewise says larger putamen and pallidum volumes were associated with more severe depersonalization/derealization symptoms, contrary to the claimed negative correlation. (LLM, conf=0.93)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Patients with PTSD+DID, but not PTSD patients without DID, showed smaller hippocampal volumes than healthy controls.

    “Patients with PTSD+DID (but not PTSD patients without DID) further showed smaller hippocampal volumes than healthy controls [103].”
  • Patients with comorbid PTSD+DID showed significantly larger volumes of the putamen and pallidum than PTSD patients without DID.

    “Patients with comorbid PTSD+DID showed significantly larger volumes of the putamen and pallidum than PTSD patients without DID [103].”

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.
