Abstract

OBJECTIVE: Bipolar disorder is associated with high risk for suicidal behavior that often develops in adolescence and young adulthood. Elucidation of involved neural systems is critical for prevention. This study of adolescents and young adults with bipolar disorder with and without a history of suicide attempts combines structural, diffusion tensor, and functional MR imaging methods to investigate implicated abnormalities in the morphology and structural and functional connectivity within frontolimbic systems. METHOD: The study had 26 participants with bipolar disorder who had a prior suicide attempt (the attempter group) and 42 participants with bipolar disorder without a suicide attempt (the nonattempter group). Regional gray matter volume, white matter integrity, and functional connectivity during processing of emotional stimuli were compared between groups, and differences were explored for relationships between imaging modalities and associations with suicide-related symptoms and behaviors. RESULTS: Compared with the nonattempter group, the attempter group showed significant reductions in gray matter volume in the orbitofrontal cortex, hippocampus, and cerebellum; white matter integrity in the uncinate fasciculus, ventral frontal, and right cerebellum regions; and amygdala functional connectivity to the left ventral and right rostral prefrontal cortex. In exploratory analyses, among attempters, there was a significant negative correlation between right rostral prefrontal connectivity and suicidal ideation and between left ventral prefrontal connectivity and attempt lethality. CONCLUSIONS: Adolescent and young adult suicide attempters with bipolar disorder demonstrate less gray matter volume and decreased structural and functional connectivity in a ventral frontolimbic neural system subserving emotion regulation. Among attempters, reductions in amygdala-prefrontal functional connectivity may be associated with severity of suicidal ideation and attempt lethality.

  • Reduced gray matter volume in the orbitofrontal cortex, anterior cingulate cortex, hippocampus, and amygdala has been linked to suicidal ideation and attempts.

    “Reduced gray matter volume in the orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), hippocampus, and amygdala has been linked to suicidal ideation and attempts (12, 13).”

    From Exploring the neurobiological markers of suicidal behaviors in pediatric population: a narrative review (2026) · cites this paper as [12]

    The Results (Group Differences Within Imaging Modalities; page unavailable) report lower gray matter volume in the orbitofrontal cortex and hippocampus of adolescent and young adult bipolar-disorder suicide attempters. They do not report a corresponding anterior cingulate finding; the Discussion explicitly says amygdala volume did not differ between groups. The association with suicidal ideation concerned functional connectivity, not gray matter volume. (LLM, conf=0.90)

  • Suicidal youth often exhibit subtle but significant structural MRI alterations in regions responsible for emotional regulation and executive functioning.

    “Structural MRI studies suggest that suicidal youth often exhibit subtle but significant alterations in regions responsible for emotional regulation and executive functioning.”

    From Exploring the neurobiological markers of suicidal behaviors in pediatric population: a narrative review (2026) · cites this paper as [12]

    The Results (page unavailable) report significant structural MRI differences in the orbitofrontal cortex and hippocampus among adolescent and young-adult suicide attempters with bipolar disorder, compared with non-attempters. The Discussion links the affected frontolimbic system to emotion regulation. The claim extends these findings to suicidal youth generally and to regions responsible for executive functioning, neither of which this study establishes. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Reduced serotonergic tone, compounded by diminished BDNF-TrkB signaling, compromises plasticity in the frontolimbic circuits whose alterations are the most reproducible neuroimaging finding in suicidal youth.

    “Reduced serotonergic tone, compounded by diminished BDNF–TrkB signaling, then compromises plasticity in the frontolimbic circuits whose alterations are the most reproducible neuroimaging finding in suicidal youth (11–13, 28).”

    From Exploring the neurobiological markers of suicidal behaviors in pediatric population: a narrative review (2026) · cites this paper as [12]

    The Conclusions and Discussion report frontolimbic structural and functional alterations in adolescent and young-adult suicide attempters with bipolar disorder. The Introduction says imaging evidence in youth is scant, so the paper does not establish that these are the most reproducible findings across suicidal youth. It also does not show that reduced serotonergic tone and BDNF–TrkB signaling compromise frontolimbic plasticity. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Compared with nonsuicidal controls, youths with a history of suicidal behavior had decreased gray matter volumes in the hippocampus and cerebellum and decreased amygdala-prefrontal functional connectivity when viewing emotional faces.

    “compared with nonsuicidal controls, youths with a history of suicidal behavior had decreased gray matter volumes in the hippocampus and cerebellum and decreased functional connectivity between the amygdala and the left ventral and right rostral PFC when viewing emotional faces (Johnston et al. 2017)”

  • Structural MRI evidence indicates reduced ventral prefrontal and orbitofrontal cortex volume in youth reporting STB.

    “Structural MRI research suggests reduced volume in the ventral prefrontal and orbitofrontal cortices among youth reporting STB”

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.
