Abstract

Mood disorders such as major depressive disorder (MDD) and bipolar disorder (BPD) are common, chronic, recurrent mental illnesses that affect the lives and functioning of millions of individuals worldwide. Growing evidence suggests that the glutamatergic system is central to the neurobiology and treatment of these disorders. Here, we review data supporting the involvement of the glutamatergic system in the pathophysiology of mood disorders as well as the efficacy of glutamatergic agents as novel therapeutics.

  • A single dose of ketamine alleviates depressive symptoms within hours in patients who have failed to respond to two or more conventional antidepressants, and the effects are sustained for 7 to 10 days.

    “A single dose of ketamine alleviates depressive symptoms within hours in patients who have failed to respond to two or more conventional antidepressants, and the effects are sustained for 7 to 10 days.”

    From Synaptic Dysfunction in Depression: Potential Therapeutic Targets (2012) · cites this paper as [47]

    Section 5.2 (Ketamine; page unavailable) reports that a single dose produced antidepressant effects within two hours in patients with treatment-resistant major depressive disorder, with effects described as lasting 1–2 weeks. It does not specify that these patients had failed two or more conventional antidepressants, and it reports a sustained response at one week in 35% of patients rather than all patients.

  • With more than 90% of CNS neurons acting through glutamatergic and GABAergic pathways, excitatory activity must be well-regulated by an inhibitory component.

    “With more than 90% of CNS neurons acting through these pathways, the excitatory activity must be well-regulated by an inhibitory component [12].”
  • The function of the CNS fundamentally relies on a delicate physiological balance between glutamatergic and GABAergic systems.

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.
