Dysregulation of adult hippocampal neuroplasticity in major depression: pathogenesis and therapeutic implications
Open accessAbstract
Major depressive disorder (MDD) was previously hypothesized to be a disease of monoamine deficiency in which low levels of monoamines in the synaptic cleft were believed to underlie depressive symptoms. More recently, however, there has been a paradigm shift toward a neuroplasticity hypothesis of depression in which downstream effects of antidepressants, such as increased neurogenesis, contribute to improvements in cognition and mood. This review takes a top-down approach to assess how changes in behavior and hippocampal-dependent circuits may be attributed to abnormalities at the molecular, structural, and synaptic level. We conclude with a discussion of how antidepressant treatments share a common effect in modulating neuroplasticity and consider outstanding questions and future perspectives.

What the sources say
- Partly supportedcites [51] Hamilton JP, Gotlib IH. Neural substrates of increased memory sensitivity for negative stimuli in major depression. Biol Psychiatry. 2008;63:1155–62. sourceExperimental — accuracy not yet measured
The Results report greater amygdala–hippocampus and amygdala–caudate-putamen functional connectivity in depressed participants during successful encoding of negative stimuli. The Methods and Results describe connectivity between the amygdala and these regions, not connectivity within the hippocampus; the claim also omits the negative-memory task condition.

The Discussion section on amygdala–hippocampus/parahippocampus resting-state connectivity reports altered connectivity between these limbic regions in adolescents with MDD. It does not report intra-hippocampal connectivity—that is, connectivity within the hippocampus—so that part of the claim is unsupported. No page number is available in our copy. (LLM, conf=0.87)

“In rodents, BDNF haploinsufficiency resulted in smaller hippocampal volume and increased anxiety-related behaviors when exposed to chronic stress80, 81.”

The indexed text (labeled Abstract, page unavailable) reports a 13.8% smaller hippocampal volume in heterozygous BDNF knockout mice and increased anxiety-related behavior in two tests. It does not report that these mice were exposed to chronic stress; its separate discussion of chronic stress describes reduced hippocampal BDNF expression and heightened anxiety, not a chronic-stress experiment in the haploinsufficient mice.

The Results section (page unavailable) reports smaller hippocampal volume in BDNF-haploinsufficient mice than in wild-type mice. The paper does not report increased anxiety-related behavior after chronic stress; the Discussion (page unavailable) says anxiety-like behavior has not been consistently observed in these mice.

The introduction (p. 2) describes abnormalities across a frontolimbic network, and the results (p. 2) report altered structural and functional connectivity in MDD. However, the Patients section (p. 4) includes participants taking psychotropic medication, so the findings do not specifically establish this account for untreated MDD.

The Discussion reports that depressed patients did not recruit the DLPFC when ignoring fearful stimuli and showed enhanced amygdala responses in the same condition. But the Correlational Analyses report a significant DLPFC–amygdala correlation only when patients attended to fearful stimuli, not when they ignored them. The claimed correlation in the ignore condition is therefore unsupported. (LLM, conf=0.90)

Section 2.2 (page not provided) says serotonin receptors modulate LTP and/or LTD and links synaptic plasticity to learning and memory.

“First, the hippocampus plays a critical role in mood regulation, in part, due to its connections with emotion-related brain regions such as amygdala and anterior cingulate cortex (ACC)17, 18 as well as its feedback role in regulating the hypothalamus-pituitary-adrenal (HPA) axis.”

“In healthy controls, when asked to downregulate emotional responses in the presence of an aversive stimuli, the PFC and ACC were hyperactivated and the amygdala was hypoactivated. When participants were asked to upregulate negative emotions in response to aversive stimuli, both the PFC and amygdala were activated47, suggesting a PFC-dependent cognitive component in emotional regulation in healthy”

The paper relies on this without support.
Antidepressant medications are pharmacologically active within hours, but their antidepressant effects are not apparent for weeks after starting treatment.
“First, although these medications are pharmacologically active within hours, their antidepressant effects are not apparent for weeks after starting treatment.”
The paper relies on this without support.
Even when antidepressants have meaningful pharmacologic effects, many patients do not improve.
“Second, even when the medications are having meaningful pharmacologic effects, many patients do not improve.”
The authors state this as an assumption.
The effects of antidepressants depend on downstream processes, such as increased neurogenesis, that take time to appear and are robust only in medication responders.
“The most widely accepted response to both questions is to assume that the effects of antidepressants are dependent on downstream processes, such as an increase in neurogenesis, that take time to appear and are only robust in medication responders.”
The paper relies on this without support.
High concentrations of hippocampal glucocorticoid receptors make the hippocampus particularly vulnerable to allostatic load.
“Third, given its role in HPA axis regulation, the high concentrations of hippocampal glucocorticoid receptors make it particularly vulnerable to allostatic load.”
The paper relies on this without support.
Hippocampal volume loss is not pathognomonic for depression and can occur in the presence of environmental stressors, other psychiatric conditions, and neurodegenerative diseases.
“Hippocampal volume loss is not pathognomonic for depression and can occur in the presence of environmental stressors, other psychiatric conditions, and neurodegenerative diseases.”

Traditional antidepressants act on the monoaminergic system to increase synaptic monoamine neurotransmitter levels.
“As previously discussed, traditional antidepressants target the monoaminergic system to increase levels of monoaminergic neurotransmitters in the synapse.”
The paper relies on this without support.
To increase LTP, some NMDA receptors must remain available.
“The dosage and affinity are important because, to increase LTP, some NMDA receptors must be available.”
The paper relies on this without support.
Neuroplasticity is integral to healthy cognitive and affective functioning.
“Neuroplasticity is integral to healthy cognitive and affective functioning.”
The paper relies on this without support.
Major depressive disorder clinical heterogeneity remains poorly understood, particularly how it relates to pathogenesis and treatment choices.
“MDD clinical heterogeneity remains poorly understood, particularly in terms of how it relates to pathogenesis and implications for treatment choices.”
The paper relies on this without support.
The duration or presence of major depression correlates with declines in neuroplasticity.
“While duration or presence of major depression correlates with declines in neuroplasticity, administration of antidepressants may reverse some of the neurobiological changes observed in MDD (Figure 4).”

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 2026-10-05, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-05 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
