Antidepressant actions of ketamine: from molecular mechanisms to clinical practice

Open access
Monteggia, Lisa M, Zarate, Carlos·2015·Current Opinion in Neurobiology

Abstract

In the past decade the emergence of glutamate N-methyl-d-aspartate (NMDA) receptor blockers such as ketamine as fast-acting antidepressants fostered a major conceptual advance by demonstrating the possibility of a rapid antidepressant response. This discovery brings unique mechanistic insight into antidepressant action, as there is a substantial amount of basic knowledge on glutamatergic neurotransmission and how blockade of NMDA receptors may elicit plasticity. The combination of this basic knowledge base and the growing clinical findings will facilitate the development of novel fast acting antidepressants.

  • Ketamine is effective for treatment-refractory symptoms including suicidality, anxiety, and anhedonia, and it affects motivation-related functional circuits.

    “ketamine has been found to be effective for traditionally treatment-refractory symptoms such as suicidality, anxiety, and anhedonia, and to impact functional circuitries related to motivation [8,9].”

    From Ketamine in neuropsychiatric disorders: an update (2024) · cites this paper as [8]

    The Introduction (page not supplied) reports a rapid antidepressant response in treatment-resistant depression and rapid antisuicidal effects. It does not report efficacy for anxiety or anhedonia, or an effect on motivation-related functional circuits. (LLM, conf=0.86)

    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 [218]

    The ‘Synaptic and neuronal basis of ketamine action’ section describes ketamine-associated BDNF upregulation through protein translation, but does not report an increase in BDNF mRNA. The ‘NMDA receptor blocker memantine does not elicit a rapid antidepressant effect’ section discusses TrkB signaling and phosphorylation of mTOR, not observed TrkB phosphorylation after acute ketamine treatment. No page numbers are available in our copy. (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.
