Abstract

BACKGROUND: Establishing an evidence-based diagnostic system informed by the biological (dys)function of the nervous system is a major priority in psychiatry. This objective, however, is often challenged by difficulties in identifying homogeneous clinical populations. Melancholia, a biological and endogenous subtype for major depressive disorder, presents a canonical test case in the search of biological nosology. METHOD: We employed a unique combination of naturalistic functional magnetic resonance imaging (fMRI) paradigms - resting state and free viewing of emotionally salient films - to search for neurobiological signatures of depression subtypes. fMRI data were acquired from 57 participants; 17 patients with melancholia, 17 patients with (non-melancholic) major depression and 23 matched healthy controls. RESULTS: Patients with melancholia showed a prominent loss of functional connectivity in hub regions [including ventral medial prefrontal cortex, anterior cingulate cortex (ACC) and superior temporal gyrus] during natural viewing, and in the posterior cingulate cortex while at rest. Of note, the default mode network showed diminished reactivity to external stimuli in melancholia, which correlated with the severity of anhedonia. Intriguingly, the subgenual ACC, a potential target for treating depression with deep brain stimulation (DBS), showed divergent changes between the two depression subtypes, with increased connectivity in the non-melancholic and decreased connectivity in the melancholic subsets. CONCLUSION: These findings reveal neurobiological changes specific to depression subtypes during ecologically valid behavioural conditions, underscoring the critical need to respect differing neurobiological processes underpinning depressive subtypes.

  • A dyshomeostasis-induced sense of low self-efficacy may play a particularly important role in melancholia, a subtype of depression with pronounced somatic symptoms and endocrine disturbances that differs physiologically from other forms of depression with respect to functional connectivity of visceromotor areas, including SGC and ACC.

    “Instead, we propose that it may play a particularly important role in melancholia, a subtype of depression with pronounced somatic symptoms and endocrine disturbances (Parker and Paterson, 2014) that differs physiologically from other forms of depression with respect to functional connectivity of visceromotor areas, including SGC and ACC (Guo et al., 2016).”
  • Decreased functional connectomes in areas of the DMN and LIM are related to anhedonia.

    “On the other hand, the decreased functional connectomes in areas of the DMN and LIM are considered to be related to anhedonia [62-68]”

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.
