Abstract

The purpose of this study was to investigate the changes in resting-state brain functional network connectivity (FNC) in young depressed patients with and without suicidal behavior, and the relationship between FNC and suicidal attempts in depressed youths using resting-state fMRI (RS-fMRI). We conducted independent component analysis (ICA) to identify intrinsically connected neural networks and analyze the alterations of intra- and inter-network connectivity using FNC analysis in 35 depressed youth with suicidal attempts (SU group), 18 patients without suicidal attempts (NSU group) and 47 healthy controls (HC), and investigate brain-behavior associations between the FNC coefficients and clinical behavior in the SU group. SU group showed significantly decreased internetwork connectivity between anterior default mode network (aDMN) and salience network (SN), as well as the right frontal-parietal network (rFPN). However, the internetwork connectivity between the SN and rFPN in SU group was higher than that in NSU group. Moreover, decreased aDMN-rFPN connectivity was negatively correlated with BHS scores, and the differences in SN-rFPN and aDMN-pDMN connectivity were negatively associated with the HAMD score in the SU group. Our findings may provide new insights into the patterns of functional organization in the brain of suicidal depressed patients.

  • In adolescents who were currently experiencing depressive symptoms and had a history of suicide attempt, decreased connectivity between the default mode, salience, and executive control networks was reported, in addition to increased connectivity between the salience and executive control networks.

    “For example, decreased connectivity between the default mode, salience, and executive control networks was reported in adolescents who were currently experiencing depressive symptoms and had a history of suicide attempt, in addition to increased connectivity between the salience and executive control networks (71).”

  • These studies have mostly assessed suicide risk in larger clinical samples of participants diagnosed with mood disorders and other psychiatric conditions with which suicide is a comorbid phenotype, but rarely have they investigated suicide transdiagnostically.

    “Finally, these studies have mostly assessed suicide risk in larger clinical samples of participants diagnosed with mood disorders (64–75) and other psychiatric conditions (76–79) with which suicide is a comorbid phenotype, but rarely have they investigated suicide transdiagnostically.”

  • In attempters, resting-state functional connectivity shows reduced positive connectivity between the default mode network and salience network.

    “Resting state functional connectivity findings highlight reduced positive connectivity between the default mode network and salience network in attempters”
  • Across ICA networks, patients with an attempt history show reduced positive RSFC between anterior DMN and salience network, less negative anterior DMN-right fronto-parietal network connectivity, and increased right FPN-SN and DMN-cerebellum connectivity compared to patients without attempt history.

    “Across ICA networks, however, there is reduced positive RSFC between the anterior portion of the DMN and the salience network (SN), less negative anterior DMN-right fronto-parietal network connectivity, as well as increased right FPN-SN and DMN-cerebellum connectivity in patients with versus without an attempt history (102, 103).”
  • Compared to psychiatric controls, attempters show increased connectivity between an ICA-derived DMN component and cerebellum and lingual gyrus, and decreased connectivity with precuneus.

    “Compared to psychiatric controls, attempters show increased connectivity between an ICA-derived DMN component and the cerebellum and lingual gyrus, and decreased connectivity with precuneus.”

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.
