Abstract

Depression is one of the most common psychological diseases with significant potential morbidity and mortality. Although the underlying pathophysiology of depression has not been clearly defined, preclinical and clinical evidence suggest disturbances in serotonin (5-HT), norepinephrine (NE), and dopamine (DA) neurotransmission in the central nervous system. Virtually all currently available antidepressants act on one or more of the following mechanisms: inhibition of reuptake of 5-HT or NE (and DA), antagonism of inhibitory presynaptic 5-HT or NE receptors, or inhibition of monoamine oxidase. All of these mechanisms result in an enhanced neurotransmission of 5-HT and/or NE. Evidence for the involvement of NE in depression is abundant, and recent studies on neuronal pathways and symptoms highlight the specific role of NE in this disorder. NE plays a determinant role in executive functioning regulating cognition, motivation, and intellect, which are fundamental in social relationships. Social dysfunction is possibly one of the most important factors affecting the quality of life in depressed patients.

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

  • The pathophysiology of depression is complex and includes social environmental stress factors; genetic and biological processes, such as the overdrive of the HPA axis, inflammation, and disturbances in monoamine neurotransmission.

    “The pathophysiology of depression is complex and includes social environmental stress factors; genetic and biological processes, such as the overdrive of the HPA axis, inflammation (31), and disturbances in monamine neurotransmission as described above (91).”
  • NE is a neurotransmitter of major importance in the pathophysiology and treatment of depressive disorders.

    “Several lines of evidence suggest that NE is a neurotransmitter of major importance in the pathophysiology and treatment of depressive disorders (91).”
  • Experimental depletion of NE in the brain leads to a return of depressive symptoms after successful treatment with NE antidepressant drugs.

    “Thus, experimental depletion of NE in the brain led to a return of depressive symptoms after successful treatment with NE antidepressant drugs (91).”

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.
