The relationship between disrupted anhedonia-related circuitry and suicidal ideation in major depressive disorder: A network-based analysis. Neuroimage Clin 2023; 40:103512.

Abstract
BACKGROUND Several epidemiological studies and psychological models have suggested that major depressive disorder (MDD) with anhedonia is associated with suicidal ideation (SI). However, little is known about whether the functional network pattern and intrinsic topologically disrupted in patients with anhedonia are related to SI. METHODS The resting-fMRI by applying network-based statistic (NBS) and graph-theory analyses was estimated in 273 patients with MDD (144 high anhedonia [HA], 129 low anhedonia [LA]) and 150 healthy controls. In addition, we quantified the SI scores of each patient. Finally, the mediation analysis assessed whether anhedonia symptoms could mediate the relationship between anhedonia-related network metrics and SI. RESULT The NBS analysis demonstrated that individuals with HA have a single abnormally increased functional connectivity component in a frontal-limbic circuit (termed the "anhedonia-related network", including the frontal cortex, striatum, anterior cingulate cortex and amygdala). The graph-theory analysis demonstrated that the anhedonia-related network showed a significantly disrupted topological organization (lower gamma and lambda), which the small-world property trend randomized. Furthermore, the anhedonia symptoms could mediate the relationship between the anhedonia-related network metrics (the mean functional connectivity values, the area under the curves values of gamma and nodal local efficiency in nucleus accumbens) and SI. CONCLUSIONS We found that disruption of the reward-related network in MDD leads to SI through anhedonia symptoms. These findings show the abnormal topological construction of functional brain network organization in anhedonia, shedding light on the neurological processes underlying SI in MDD patients with anhedonia symptoms.

Darquennes G, Wacquier B, Loas G, Hein M. Suicidal Ideations in Major Depressed Subjects: Role of the Temporal Dynamics of Anhedonia. Brain Sci 2023; 13:1065. [PMID: 37508997 PMCID: PMC10377246 DOI: 10.3390/brainsci13071065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 07/10/2023] [Accepted: 07/12/2023] [Indexed: 07/30/2023] Open
Abstract
Given the limited data available in the literature, the aim of this study was to investigate the potential role played by the temporal dynamics of anhedonia (lifelong anhedonia and recent changes in anhedonia) in the occurrence of suicidal ideations in major depressed subjects. The clinical data of 285 major depressed subjects recruited from the database of the Erasme Hospital Sleep Laboratory were analyzed. A score on item nine of the Beck Depression Inventory (BDI-II) ≥1 and/or an identification during the systematic psychiatric assessment were used to determine the presence of suicidal ideations. The association between anhedonia complaints (lifelong anhedonia and recent change in anhedonia) and suicidal ideations in major depressed subjects was assessed by logistic regression analyzes. The prevalence of suicidal ideations was 39.3% in our sample of major depressed subjects. After adjusting for the main confounding factors, multivariate logistic regression analysis demonstrated that unlike lifelong anhedonia, only recent changes in anhedonia were a risk factor for suicidal ideations in major depressed subjects. Given this potential involvement of the recent change in anhedonia in the occurrence of suicidal ideations in major depressed subjects, it seems essential to better identify and adequately manage this specific form of anhedonia in order to open new perspectives for the prevention of suicide in this particular sub-population.

Abstract
BackgroundsDecision-making deficits have been reported as trans-diagnostic characteristics of vulnerability to suicidal behaviors, independent of co-existing psychiatric disorders. Individuals with suicidal behaviors often regret their decision to attempt suicide and may have impairments in future-oriented processing. However, it is not clear how people with suicidal dispositions use future-oriented cognition and past experience of regret to guide decision-making. Here, we examined the processes of regret anticipation and experience in subclinical youth with and without suicidal ideation during value-based decision-making.MethodsIn total, 80 young adults with suicidal ideation and 79 healthy controls completed a computational counterfactual thinking task and self-reported measures of suicidal behaviors, depression, anxiety, impulsivity, rumination, hopelessness, and childhood maltreatment.ResultsIndividuals with suicidal ideation showed a reduced ability to anticipate regret compared to healthy controls. Specifically, suicidal ideators’ experience of regret/relief was significantly different from that of healthy controls upon obtained outcomes, while their disappointment/pleasure experience was not significantly different from healthy controls.ConclusionThese findings suggest that young adults with suicidal ideation have difficulty predicting the consequences or the future value of their behavior. Individuals with suicidal ideation showed impairments in value comparison and flat affect to retrospective rewards, whereas individuals with high suicidality showed blunted affect to immediate rewards. Identifying the counterfactual decision-making characteristics of at-risk suicidal individuals may help to elucidate measurable markers of suicidal vulnerability and identify future intervention targets.

[PMID: 36603315 DOI: 10.1016/j.jpsychires.2022.12.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 12/11/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022]
Abstract
Previous studies have evaluated the relationship between anhedonia and suicidality; however, to our knowledge, there has been no quantitative synthesis evaluating the foregoing association to date. Herein, this meta-analysis aims to provide a quantitative synthesis of the extant literature reporting on the association between levels of anhedonia across all dimensions (e.g., anticipatory, consummatory) amongst individuals endorsing suicidality. Online databases (i.e., PubMed, PsycINFO, Google Scholar) were searched from inception to 13 June 2022. Studies which assessed an aspect of suicidality (i.e., ideation, attempts) and a validated anhedonia scale were included. The risk of bias was assessed using the ROBINS-1 tool, and the quality of the sources was evaluated using GRADE criteria. The results of the studies were quantitatively synthesized using Pearson's r effect sizes via a random-effects meta-analysis. A total of 20 studies and 11,212 individuals were included in the final quantitative synthesis. Overall, results indicate that anhedonia has a significant and moderate correlation with suicidality in general and psychiatric populations (r = 0.31, p < 0.001 and r = 0.32, p < 0.001 respectively). Sub-analysis suggests a larger effect of anticipatory and consummatory interpersonal anhedonia (r = 0.40, p < 0.001). The identification of increased levels of anhedonia in individuals with suicidality indicates that anhedonia may be a core risk factor for suicidal ideation and behaviours. Future studies should endeavour to develop a comprehensive risk assessment encompassing all domains of anhedonia which can be utilized in a primary care setting as a potential prevention strategy for suicidal behaviours and outcomes.

Intersecting identities and adolescent depression: Patterns of depressed mood and anhedonia in the past decade. J Affect Disord 2022; 319:518-525. [PMID: 36162694 DOI: 10.1016/j.jad.2022.09.088] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 09/16/2022] [Accepted: 09/20/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Research suggests adolescent depression is increasing and certain adolescents may be uniquely vulnerable. However, limited conceptualizations of identity and time, as well as the reliance on unitary conceptualizations of depression, inhibits a nuanced perspective on these trends. In response, we examined how adolescent depressive symptoms, depressed mood, and anhedonia, vary across intersecting identities over time. METHODS Secondary data analysis on the National Survey on Drug Use and Health between 2009 and 2017 was conducted. In total 145,499 nationally representative adolescents (ages 12-17) completed a diagnostic assessment for depression. Lifetime and past year reports of depressive symptoms, depressed mood, and anhedonia were treated as separate variables. A novel, mixed-level model in which participants were nested within identity (defined by one's age, gender, race/ethnicity, poverty level) and time was used to test our aims. RESULTS Overall, the relation between depression outcomes and identity did not vary over time (p > .01). Further, identity's impact on depression was approximately ten-fold that of temporal effects. Multiracial, late adolescent, female adolescents were at particular risk. Findings concerning depressed mood and anhedonia were similar across analyses. LIMITATIONS All facets of identity (e.g., sexual identity) were not included in the model and a unidimensional measure of poverty may have underestimated its depressogenic influence. CONCLUSION Adolescent depression outcomes are mostly consistent across criterial symptom subtypes and time, but vary as a function of identity. Prevention protocols that highlight mechanisms of risk tethered to social identity, and include salient experiences of females, late adolescents, and multiracial youth in particular, need to be prioritized in mental health initiatives.

Abstract
The aim of the study was to explore in depression the relationship between recent suicidal ideation and the different anhedonias taking into account the severity of depression. Recent studies have suggested that recent change of anhedonia and not state or trait anhedonia is associated with recent suicidal ideations even when the level of depression is controlled. Three samples were used (74 severe major depressives, 43 outpatients with somatic disorders presenting mild or moderate depression and 36 mild or moderate depressives hospitalized in the intensive coronary unit). Recent change of anhedonia was rated by the anhedonia subscale of the Beck Depression Inventory (BDI-II), state anhedonia by the Snaith-Hamilton Pleasure Scale (SHAPS), trait anhedonia by the TEPS (Temporal Experience of Pleasure Scale), musical anhedonia by the BMRQ (Barcelona Music Reward Questionnaire), social recent change of anhedonia by the SLIPS (Specific Loss of Interest and Pleasure Scale), the severity of depression by the BDI-II and the distinction between melancholic and non-melancholic was found using a subscale of the BDI-II. Bivariate and multivariate regression analyses were performed in each sample. In severe major depressives and, notably, in melancholia, recent suicidal ideation was associated with trait anhedonia; however, in mild or moderate depression, recent suicidal ideation was associated with recent change of anhedonia. Musical anhedonia and social recent change of anhedonia were not associated with recent suicidal ideation. Trait anhedonia could be, in severe depression, a strong predictor of recent suicidal ideation.

Risk of current suicidal ideations associated with lifelong anhedonia and recent change of anhedonia in individuals with insomnia: A cross-sectional study. J Psychiatr Res 2022; 150:338-345. [PMID: 34838265 DOI: 10.1016/j.jpsychires.2021.11.034] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 11/02/2021] [Accepted: 11/20/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Individuals with insomnia are a subpopulation at high-risk of suicide. However, despite the elements in favour of an implication of anhedonia in the occurrence of current suicidal ideations (SI), no study has investigated the role played by this affective symptom in the occurrence of current SI in individuals with insomnia. The aim of this study was to investigate the risk of current SI associated with lifelong anhedonia and recent change of anhedonia in individuals with insomnia. METHOD Demographic and polysomnographic data from 493 individuals with insomnia selected retrospectively from the clinical database of the Erasme Hospital Sleep Laboratory were analysed. Current SI were considered present if the score in item 9 of the Beck Depression Inventory (BDI-II) was ≥1 and/or if they were highlighted during the systematic psychiatric assessment conducted on admission to the Sleep Laboratory. Logistic regression analyses were used to determine the risk of current SI associated with anhedonia in individuals with insomnia. RESULTS The prevalence of current SI was 21.5% in our sample of individuals with insomnia. After adjusting for major confounding factors, multivariate logistic regression analyses demonstrated that unlike lifelong anhedonia, only recent change of anhedonia was a risk factor for current SI in individuals with insomnia. CONCLUSION In this study, we demonstrated that in individuals with insomnia, recent change of anhedonia is a risk factor for current SI, which seems to justify more systematic research and adequate therapeutic management of this condition to allow better prevention in this particular subpopulation at high-risk of suicide.

Abstract
Suicide is a leading cause of death and morbidity worldwide, yet few interventions are available to mitigate its risk. Barriers to effective treatments involve a limited understanding of factors that predict the onset of suicidal thoughts and behaviors. In the context of suicide risk, stress is a precipitating factor that is largely overlooked in the literature. Indeed, the pathophysiology of stress and suicide are heavily interconnected, underscoring the need to target the stress system in suicide prevention. In this review, we integrate findings from the preclinical and clinical literature that links stress and suicide. We focus specifically on the effects of stress on underlying biological functions and processes associated with suicide, allowing for the review of research using animal models. Owing to the rapid anti-suicidal effects of (R,S)-ketamine, we discuss its ability to modulate various stress-related endophenotypes of suicide, as well as its potential role in preventing suicide in those with a history of chronic life stress (e.g., early life adversity). We highlight future research directions that could advance our understanding of stress-related effects on suicide risk, advocating a dimensional, endophenotype approach to suicide research. Suicide and chronic stress pathophysiology are interconnected. Chronic stress has profound impacts on several endophenotypes of suicide. Animal and human research points to stress as a precipitating factor in suicide. Ketamine modulates specific biological processes associated with stress and suicide. Suicide research into endophenotypes can help inform risk-mitigation strategies.

Abstract
BACKGROUND Evidence suggests that recent changes in anhedonia may be more predictive of suicidal ideation than either state or trait anhedonia alone. However, the individual role that anhedonia symptoms play in suicidality is not yet well established. METHODS This study investigated whether state, trait, and recent changes in anhedonia predicted recent suicidal ideation, using cross-sectional data from two independent samples, one non-clinical (n = 2,138) and one clinical (n = 859), using binary logistic regression analyses. RESULTS In Study 1, loss of interest in people and loss of pleasure were associated with recent suicidal ideation independent of other depression symptoms, state and trait anhedonia. In Study 2, loss of interest in people, loss of interest in sex, and work inhibition were associated with recent suicidal ideation. In both studies, recent changes in anhedonia was uniquely associated with recent suicidal ideation. CONCLUSIONS These results indicate that recent changes in anhedonia and particularly the social aspect of the Loss of Interest in People item could be a significant risk factor in suicidal ideation.

Abstract
OBJECTIVE This study aims to investigate the indirect effect of impulsiveness on suicidal ideation through depression and the moderating effect of impulsiveness on the indirect effect in an integrated path model. METHODS Self-rating depression scale (SDS), Barratt impulsiveness scale-11th version (BIS-11), and self-rating idea of suicide scale (SIOSS) were applied. A moderated mediation path model was established including impulsiveness, depression, and suicidal ideation as observed variables. RESULTS The main results revealed that the moderated mediation path model fit well in describing the relationships among impulsiveness, depression, and suicidal ideation. The indirect effect of impulsiveness mediated by depression and the moderating effect of impulsiveness on suicidal ideation was significant. Multiple comparisons showed that the indirect effects under different conditions of impulsiveness had statistical differences. The higher the impulsiveness was, the stronger the predictive effect of depression on suicidal ideation was. CONCLUSIONS The present study confirms that people who have impulsive traits are riskier to generate suicidal thoughts because they are more likely to suffer from depression and that people who are depressive have even higher risk to develop suicidal thoughts when they simultaneously have impulsive traits. In clinical and health care work, when considering depression to prevent suicidal ideation, impulsiveness needs to be monitored throughout the process of premorbid and onset stages of depression.

Abstract
The aim of the study was to explore the relationships between recent changes of anhedonia or particular symptoms of recent changes of anhedonia and suicidal ideation taking into account the severity of suicidal ideations. In a group of 173 medical students, scores of the anhedonia subscale (ANH-BDI) of the BDI-II (i.e. 4 anhedonia items: loss of pleasure, loss of interest, loss of energy and loss of interest in sex) were compared between 95 subjects without suicidality, 24 subjects with life-time suicidal ideation, 28 subjects with recent suicidal ideation and 26 planners. Analyses of covariance (ANCOVA) were performed referring to groups as independent variables, the cognitive-affective subscale (CA-BDI) of the BDI-II as a covariate, the ANH-BDI and each of the four anhedonia items as dependent variables. High levels of loss of interest characterized planners when compared to the other three groups. Loss of interest could be associated with recent and severe suicidal ideation.

Abstract
Abstract. Background: Recent work suggests that state anhedonia and its social aspect of loss of interest in people was an important predictor of suicidal ideation in adults. Aim: The current study investigated the relationship between state anhedonia, trait anhedonia, suicidal ideation, and suicide attempts in adolescents. Method: State anhedonia was assessed using the anhedonia subscale from the Child Mood and Feelings Questionnaire, while trait social anhedonia was assessed using the Adolescent Anticipatory and Consummatory Interpersonal Pleasure Scale and the Temporal Experience of Pleasure Scale. Results: Results indicated that state anhedonia was associated with suicidal ideation but not associated with past suicide attempts after controlling for depressive symptoms. Academic stressful events moderated the relationship between state anhedonia and suicidal ideation. Symptom-level analyses revealed that loss of interest in friends was most highly predictive of suicidal ideation compared with the other anhedonia components. Limitations: The current investigation was limited by its reliance on student samples and data from a single time point. Conclusion: The current study indicated that state anhedonia and its social component may be more informative of near-term suicidal ideation than trait anhedonia in adolescents.

Abstract
OBJECTIVE Our primary aim was to test the Interpersonal Theory of Suicide's synergy hypothesis (i.e., the interaction between perceived burdensomeness and thwarted belongingness) in the proximal prediction of suicide ideation, while accounting for quadratic effects. METHOD We used MTurk to recruit participants (N = 478) with a lifetime history of suicidal thoughts and behaviors; they completed two batteries of self-report questionnaires three days apart. RESULTS Contrary to the synergy hypothesis, only suicide ideation and the quadratic effect of perceived burdensomeness at Time 1 were significant predictors of suicide ideation at Time 2. The quadratic effect of perceived burdensomeness indicated a u-shaped function, whereby scores at or above the 80th percentile on perceived burdensomeness at Time 1 had increasingly strong, positive associations with suicide ideation at Time 2, while scores under the 80th percentile were not predictive of suicide ideation at Time 2. Also, thwarted belongingness and suicide ideation at Time 1 were significant predictors of perceived burdensomeness at Time 2. CONCLUSIONS These findings add to a growing literature that does not support the synergy hypothesis and suggests the importance of including nonlinear terms when examining the Interpersonal Theory of Suicide's constructs.

Abstract
BACKGROUND Recent works suggested taking into account the severity and the type of anhedonia when examining suicidal ideation. The present study investigated a moderated mediation model addressing the psychosocial mechanisms that account for the association between state or trait anhedonia and suicidal ideation. METHODS State anhedonia was assessed using the Snaith-Hamilton Pleasure Scale, while trait anhedonia was assessed using the Temporal Experience of Pleasure Scale. A total number of 1,361 of undergraduates completed questionnaires at three different times, with one-year intervals. RESULTS The direct effect of stress on suicidal ideation was significantly greater for those students who had lower trait anticipatory and consummatory anhedonia, whereas the indirect effect from stress on suicidal ideation through depression was significantly greater for those who had higher state anhedonia. Moreover, trait consummatory anhedonia moderated the relationship between stress and suicidal ideation after one year, and trait anticipatory anhedonia moderated the relationship between stress and suicidal ideation after two years. CONCLUSIONS Low levels of trait anhedonia were associated with elevated suicidal ideation, while high levels of state anhedonia were associated with elevated suicidal ideation. Trait consummatory anhedonia was associated with short-term suicidal ideation, while trait anticipatory anhedonia was associated with long-term suicidal ideation.
