The Impact of Stress and Major Depressive Disorder on Hippocampal and Medial Prefrontal Cortex Morphology
Open accessAbstract
Volumetric reductions in the hippocampus and medial prefrontal cortex (mPFC) are among the most well-documented neural abnormalities in major depressive disorder (MDD). Hippocampal and mPFC structural reductions have been specifically tied to MDD illness progression markers, including greater number of major depressive episodes (MDEs), longer illness duration, and nonremission/treatment resistance. Chronic stress plays a critical role in the development of hippocampal and mPFC deficits, with some studies suggesting that these deficits occur irrespective of MDE occurrence. However, preclinical and human research also points to other stress-mediated neurotoxic processes, including enhanced inflammation and neurotransmitter disturbances, which may require the presence of an MDE and contribute to further brain structural decline as the illness advances. Specifically, hypothalamic-pituitary-adrenal axis dysfunction, enhanced inflammation and oxidative stress, and neurotransmitter abnormalities (e.g., serotonin, glutamate, gamma-aminobutyric acid) likely interact to facilitate illness progression in MDD. Congruent with stress sensitization models of MDD, with each consecutive MDE it may take lower levels of stress to trigger these neurotoxic pathways, leading to more pronounced brain volumetric reductions. Given that stress and MDD have overlapping and distinct influences on neurobiological pathways implicated in hippocampal and mPFC structural decline, further work is needed to clarify which precise mechanisms ultimately contribute to MDD development and maintenance.

Findings from animal models of stress and depression can be generalized to human major depressive disorder neurobiology.
“Animal models have established that prolonged stress can lead to HPA axis hyperreactivity and depressive behaviors along with hippocampal and mPFC abnormalities (68,69).”
The paper relies on this without support.
Hippocampal and medial prefrontal cortex volume reductions measured by MRI reflect cellular damage or atrophy relevant to major depressive disorder.
“Volumetric reductions in the hippocampus and medial prefrontal cortex (mPFC) are among the most well documented neural abnormalities in major depressive disorder (MDD).”
The paper relies on this without support.
Peripheral and central measures of inflammation, oxidative stress, cortisol, and neurotransmitters index the same brain processes relevant to hippocampal and medial prefrontal cortex structure.
“higher levels of peripheral pro-inflammatory cytokines, greater expression of inflammation-related genes, and reduced expression of neuroprotective genes, have all been associated with greater hippocampal volume decline and mPFC thinning in MDD (95–97).”
The paper relies on this without support.
The stress sensitization and stress autonomy models apply to structural brain changes, not only to the onset of major depressive episodes.
“Two classes of stress-related models, the stress sensitization and stress autonomy models, have been proposed to explain how relationships between stress and depression change as a function of illness course (50).”
The paper relies on this without support.
The proposed indoleamine 2,3-dioxygenase-kynurenine pathway operates in humans with major depressive disorder as described.
“One possible common pathway involves chronic stress triggering HPA axis dysfunction and enhanced production of cell-mediated immune cytokines, which activate indoleamine 2,3-dioxygenase (IDO;68).”
The paper relies on this without support.
Major depressive disorder illness progression markers such as episode count, illness duration, and treatment resistance reflect a common progressive disease process.
“they have been consistently associated with markers of a progressive course of MDD characterized by more recurrent episodes/relapses (3,19–25), longer illness duration (24,26–30), and non-remission/treatment resistance (28,31–38).”

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.
A language model drew the claims from the paper on 2026-10-04, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-04 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
