Abstract

There is a high prevalence of non-suicidal self-injury (NSSI) amongst adolescents worldwide and therefore an urgency to investigate the underlying mechanisms that may facilitate such behaviours. This study aimed to investigate neurobiological alterations, specifically in regional brain volumes of the frontolimbic system, in adolescents engaging in NSSI in comparison to healthy controls. Regional grey matter volumes were compared between 29 adolescent female patients who presented with incidents of NSSI on ≥5 days within the last 12 months (DSM-5 criteria for NSSI) and 21 healthy age, gender and education matched controls who had never received any psychiatric diagnosis/treatment, or engaged in NSSI. Significant group effects in regional brain volumes were observed in insula, and a suggested change in the anterior cingulate cortex (ACC), while controlling for total segmented volume. Additionally, ACC volume showed a significant association with past suicide attempts, where estimated marginal means showed even smaller ACC volume in adolescents engaging in NSSI with a history of suicide attempt in comparison to those with no history of suicide attempt, including healthy controls. This study provides the first evidence of volumetric changes in adolescents engaging in NSSI and a potential neurobiological link between NSSI and suicide attempt.

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?

  • Reduced anterior cingulate cortex volume is associated with STB and NSSI in youth.

    “there is reduced anterior cingulate cortex volume related to STB and NSSI.”
  • Compared with healthy controls, self-injurers show reduced insula gray matter volume, but this is not substantiated in BPD youth reporting parasuicidal behaviors.

    “In comparison to healthy controls, self-injurers show reduced insula GMV (62, 64), but this is not substantiated in BPD youth reporting parasuicidal behaviors (65).”
  • Among adolescents with BPD, more lifetime parasuicidal behaviors in the past 6 months associates with smaller left ACC volume, consistent with findings comparing past-year self-injurers and healthy youth.

    “Among adolescents with BPD, a greater number of lifetime parasuicidal behaviors in the past 6 months associates with smaller left ACC volume (69), consistent with findings comparing past-year self-injurers and healthy youth (64).”
  • NSSI research reveals ACC structural alterations and disruptions in amygdala and ACC connectivity, which contribute to hyperarousal and reduced impulse control, central features of NSSI.

    “By contrast, NSSI research reveals ACC structural alterations (64, 69) as well as disruptions in amygdala and ACC connectivity (96), which contributes to hyperarousal and reduced impulse control—central features of NSSI (110, 111).”

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.
