Abstract

Ketamine is the prototype for a new generation of glutamate-based antidepressants that rapidly alleviate depression within hours of treatment. Over the past decade, there has been replicated evidence demonstrating the rapid and potent antidepressant effects of ketamine in treatment-resistant depression. Moreover, preclinical and biomarker studies have begun to elucidate the mechanism underlying the rapid antidepressant effects of ketamine, offering a new window into the biology of depression and identifying a plethora of potential treatment targets. This article discusses the efficacy, safety, and tolerability of ketamine, summarizes the neurobiology of depression, reviews the mechanisms underlying the rapid antidepressant effects of ketamine, and discusses the prospects for next-generation rapid-acting antidepressants.

  • Depression is characterized at the molecular level as a failure of neuroplasticity, including neuronal atrophy and synaptic depression in the medial prefrontal cortex (mPFC) and hippocampus.

    “At the molecular level, depression has been characterized as a failure of neuroplasticity, including neuronal atrophy and synaptic depression in the medial prefrontal cortex (mPFC) and hippocampus 3-5 .”

    From Neuroplasticity in cognitive and psychological mechanisms of depression: an integrative model (2020) · cites this paper as [3]

    The section “Synaptic Homeostasis and the Neurobiology of Depression” links depression to altered synaptic plasticity and reports neuronal atrophy and synaptic depression in the prefrontal cortex and hippocampus. It says prefrontal cortex (PFC), however, without specifying the medial prefrontal cortex (mPFC) as the claim does. Page numbers were not available in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Attempts to extend molecular findings to humans (e.g., BDNF and synapse levels) have yielded inconsistent results.

    “While molecular neuroplasticity effects are well-described in rodent models, attempts to extend molecular findings to humans (e.g., BDNF and synapse levels) have yielded inconsistent results 3 , in no small part because of the difficulty of assessing these endpoints in the living brain, the tissue of interest.”

    From Neuroplasticity in cognitive and psychological mechanisms of depression: an integrative model (2020) · cites this paper as [3]

    The 'Restoration of Neurotrophic Function' section reports mixed human findings for peripheral BDNF after ketamine: an early study found no relationship with response, while a larger trial found a positive relationship. It discusses an indirect EEG marker of synaptic strength, but does not report similarly inconsistent findings for human synapse levels. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Impairments of neuroplasticity often characterize disorders of negative affect including depression.

    “Impairments of neuroplasticity often characterize disorders of negative affect including depression 3,4 and multiple efficacious therapies often reverse such deficits 10,148-151 .”

    From Neuroplasticity in cognitive and psychological mechanisms of depression: an integrative model (2020) · cites this paper as [3]

    The “Synaptic Homeostasis and the Neurobiology of Depression” section associates depression with neuronal atrophy, reduced synaptic connectivity, and other changes in synaptic plasticity. It supports the claim for depression, but does not establish that these impairments often characterize disorders of negative affect more broadly. Page numbers are not available in the supplied passages. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Ketamine administration reverses synaptic loss and depressive-like behavior induced by chronic stress in preclinical models.

    “Pioneering preclinical work carried out by Duman et al. indicates that administration of ketamine reverses the synaptic loss and depressive-like behavior induced by chronic stress 15,29,30 .”

    From Imaging the effect of ketamine on synaptic density (SV2A) in the living brain (2022) · cites this paper as [30]

    The review’s “Synaptogenesis and the Rapid Antidepressant Effects of Ketamine” section (page unavailable) says that ketamine rapidly opposes stress-induced prefrontal neuronal atrophy and synaptic dysconnectivity, and it reports antidepressant effects in rodents. It does not specifically state that ketamine reverses depressive-like behavior induced by chronic stress. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Similar results in BDNF mRNA and TrkB phosphorylation have been observed after acute treatment with ketamine.

    “Similar results in BDNF mRNA and TrkB phosphorylation have been observed after acute treatment with ketamine [216,217,218,219].”

    From Neurotrophic Factor BDNF, Physiological Functions and Therapeutic Potential in Depression, Neurodegeneration and Brain Cancer (2020) · cites this paper as [217]

    In “Synaptogenesis and the Rapid Antidepressant Effects of Ketamine” (page unavailable), the review reports increased BDNF translation after acute ketamine treatment. It does not report increased BDNF mRNA or TrkB phosphorylation; the phosphorylation it names is reduced eEF2 phosphorylation. (LLM, conf=0.82)

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.
