Abstract

Background Cumulative adversity and stress are associated with risk of psychiatric disorders. While basic science studies show repeated and chronic stress effects on prefrontal and limbic neurons, human studies examining cumulative stress and effects on brain morphology are rare. Thus, we assessed whether cumulative adversity is associated with differences in gray matter volume, particularly in regions regulating emotion, self-control, and top-down processing in a community sample.Methods One hundred three healthy community participants, aged 18 to 48 and 68% male, completed interview assessment of cumulative adversity and a structural magnetic resonance imaging protocol. Whole-brain voxel-based-morphometry analysis was performed adjusting for age, gender, and total intracranial volume.Results Cumulative adversity was associated with smaller volume in medial prefrontal cortex (PFC), insular cortex, and subgenual anterior cingulate regions (familywise error corrected, p < .001). Recent stressful life events were associated with smaller volume in two clusters: the medial PFC and the right insula. Life trauma was associated with smaller volume in the medial PFC, anterior cingulate, and subgenual regions. The interaction of greater subjective chronic stress and greater cumulative life events was associated with smaller volume in the orbitofrontal cortex, insula, and anterior and subgenual cingulate regions.Conclusions Current results demonstrate that increasing cumulative exposure to adverse life events is associated with smaller gray matter volume in key prefrontal and limbic regions involved in stress, emotion and reward regulation, and impulse control. These differences found in community participants may serve to mediate vulnerability to depression, addiction, and other stress-related psychopathology.

  • Despite limitations of retrospective measures, studies relying on retrospective reports of cumulative life stress have shown that lifetime stressor exposure negatively affects health-related processes and outcomes, including autonomic nervous system activity, systemic inflammatory activity, brain structure and function, rates of alcohol use, and physical and mental health status.

    “Despite the limitations of retrospective measures of historical life stress exposure, studies relying on retrospective reports of cumulative life stress have been illuminating in showing that lifetime stressor exposure negatively affects health-related processes and outcomes, including autonomic nervous system activity (Lampert et al., 2016), systemic inflammatory activity (O’Donovan et al., 2012a”

  • Higher cumulative adversity has been associated with reduced gray matter in several areas within the prefrontal cortex, including the mPFC, anterior cingulate, and insula.

    “Higher cumulative adversity has been associated with reduced gray matter in the several areas within the prefrontal cortex, including the mPFC, anterior cingulate, and insula (Ansell et al., 2012).”

    The Abstract Results report that cumulative adversity was associated with smaller gray matter volume in the medial prefrontal cortex, insular cortex, and subgenual anterior cingulate. The claim’s association and named regions are supported, but the paper does not place all three regions within the prefrontal cortex; it describes them as prefrontal and limbic regions.

  • In humans, chronic stress exposure is associated with reduced gray matter volume in dlPFC and mPFC and spine loss from the orbital PFC.

    Citation 27 is attached to the mPFC gray-matter-volume finding, not the dlPFC or orbital-PFC spine-loss claims. The Discussion reports smaller medial prefrontal volume with greater cumulative adversity, but also states that chronic stress alone was not independently associated with structural changes; the association involving chronic stress was an interaction with cumulative adverse events. (LLM, conf=0.87)

  • The loss of PFC gray matter with chronic stress has also been documented in humans.

    The Discussion (page not specified in our copy) reports smaller prefrontal gray matter volume in humans with greater cumulative adversity, and smaller orbitofrontal volume when adversity was accompanied by greater chronic stress. It also says chronic stress alone was not independently associated with structural changes. The study documents associations, not a measured loss of PFC gray matter over time caused by chronic stress. (LLM, conf=0.86)

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.
