Glutamatergic mechanisms in schizophrenia

Tsai, Guochuan, Coyle, Joseph T.·2002·Annual Review of Pharmacology and Toxicology

Abstract

Schizophrenia is a chronic, severely disabling brain disorder with symptomatic onset in early adulthood. Typical antipsychotic medications that block dopamine D2 receptors are most effective in treating the psychosis but have limited effects on the negative symptoms and cognitive impairments. Considerable research has demonstrated that noncompetitive NMDA receptor antagonists, the dissociative anaesthetic like phencyclidine and ketamine, reproduce the cardinal symptomatic features of schizophrenia. Postmortem studies reveal variable alterations in glutamate receptors and their modulators in schizophrenia. Several clinical trials indicate agents that enhance NMDA receptor function via the glycine modulatory site reduce negative and variably improve cognitive function in schizophrenics receiving typical antipsychotics. Thus, hypofunction of a subpopulation of cortico-limbic NMDA receptors may participate in the pathophysiology of schizophrenia.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The resemblance between patient contrast response curves and NMDA antagonist effects is consistent with glutamatergic theories of schizophrenia.

    “The decreased slope at low contrast and decreased plateau in patients closely resembles results seen after microinfusion of an NDMA antagonist into cat LGN and visual cortex (16,17) (Figure 3A and 3B), consistent with glutamatergic theories of schizophrenia (23–25).”

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.
