Psychiatry Res Neuroimaging 2024; 344:111888. [PMID: 39236486 DOI: 10.1016/j.pscychresns.2024.111888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 08/23/2024] [Accepted: 08/28/2024] [Indexed: 09/07/2024]
Abstract
BACKGROUND The experience of self-hood in posttraumatic stress disorder (PTSD) is altered cognitively and somatically. Dysfunctional negative cognitions about the self are a central mechanism of PTSD symptomatology and treatment. However, while higher-order brain models of disturbances in self-appraisal (i.e., cognitive processes relating to evaluating the self) have been examined in other psychiatric disorders, it is unclear how normative brain function during self-appraisal is impaired in PTSD. METHODS This paper presents a PRISMA systematic review of functional neuroimaging studies (n = 5), to establish a neurobiological account of how self-appraisal processes are disturbed in PTSD. The review was prospectively registered with PROSPERO (CRD42023450509). RESULTS Self-appraisal in PTSD is linked to disrupted activity in core self-processing regions of the Default Mode Network (DMN); and regions involved in cognitive control and emotion regulation, salience and valuation. LIMITATIONS Because self-appraisal in PTSD is relatively under-studied, only a small number of studies could be included for review. Cross-study heterogeneity in analytic approaches and trauma-exposure history prohibited a quantitative meta-analysis. CONCLUSIONS This paper proposes a mechanistic account of how neural dysfunctions may manifest clinically in PTSD and inform targeted selection of appropriate treatment options. We present a research agenda for future work to advance the field.

A network analysis of eating disorder, PTSD, major depression, state-trait anxiety, and quality of life measures in eating disorder patients treated in residential care. EUROPEAN EATING DISORDERS REVIEW 2024. [PMID: 39289909 DOI: 10.1002/erv.3136] [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: 01/11/2024] [Revised: 07/10/2024] [Accepted: 09/07/2024] [Indexed: 09/19/2024]
Abstract
BACKGROUND The network approach in the eating disorder (ED) field has confirmed important links between EDs and posttraumatic stress disorder (PTSD) symptoms. However, studies including comorbid symptoms are scarce, which limits our understanding of potentially important connections. We hypothesised that anxiety, depression and poor quality of life (QOL) would provide a more complete picture of central, maintaining factors. METHODS Network analysis using R was performed in 2178 adult ED patients (91% female) admitted to residential treatment. Assessments included the ED Examination Questionnaire (EDEQ), the Eating Disorders Inventory (EDI-2), the PTSD Checklist for DSM-5 (PTSD clusters (PCL-5)), the Patient Health Questionnaire (PHQ-9), the Spielberger State-Trait Anxiety Scale (STAI), and the ED QOL Scale (EDQOL), which measure symptoms of EDs, PTSD, major depression, state-trait anxiety, and QOL, respectively. RESULTS EDI-2 ineffectiveness showed the highest centrality (expected influence) followed by EDI-2 interoceptive awareness, STAI state anxiety, EDEQ shape concern, EDQOL psychological subscale, and PTSD cluster D (hyperarousal) symptoms. Eating Disorder Quality of Life psychological and physical-cognitive subscales and PHQ-9 major depressive, STAI state anxiety and PCL-5 PTSD cluster E (negative alterations in mood and cognition) symptoms showed the highest bridge expected influence, suggesting their interactive role in maintaining ED-PTSD comorbidity. CONCLUSIONS This is the first network analysis of the interaction between ED and PTSD symptoms to include the comorbid measures of depression, anxiety, and QOL in a large clinical sample of ED patients. Our results indicate that several symptom clusters are likely to maintain ED-PTSD comorbidity and may be important targets of integrated treatment.

Abstract
Alexithymia is characterised by difficulties in identifying, recognising, and describing emotions. We studied alexithymia in the context of speech comprehension, specifically investigating the incongruent condition between prosody and the literal meaning of words in emotion-based discourse. In two experiments, participants were categorised as having high or low alexithymia scores based on the TAS-20 scale and listened to three-sentence narratives where the emotional prosody of a key phrase or a keyword was congruent or incongruent with its literal meaning. The incongruent condition resulted in slower reaction times and lower accuracy in recognition of emotions. This incongruence effect was also evident for individuals with high alexithymia, except for anger. They recognised anger as accurately in both congruent and incongruent conditions. Contrary to our hypothesis, however, individuals with high alexithymia did not show an overall difference in emotion recognition compared to the low alexithymia group. These findings highlight the nuanced relationship between emotional prosody and literal meaning, offering insights into how individuals with varying levels of alexithymia process emotional discourse. Understanding these dynamics has implications for both cognitive research and clinical practice, providing valuable perspectives on speech comprehension, especially in situations involving incongruence between prosody and word meaning.

Abstract
Alexithymia, psychological distress, and posttraumatic stress disorder (PTSD) are highly related constructs. The ongoing debate about the nature and relationship between these constructs is perpetuated by an overreliance on cross-sectional research. We examined the longitudinal interactive relationship between alexithymia, psychological distress, and PTSD. We hypothesised that there is an interactive relationship between the three constructs. Military personnel (N = 1871) completed the Toronto Alexithymia Scale, the Kessler 10 and a PTSD Checklist (PCL-C) at pre-deployment, post-deployment, and at 3-4 years following the post-deployment assessment. We initially tested whether psychological distress is either a moderator or mediator in the relationship between alexithymia and PTSD across the time points. General psychological distress was a partial mediator of total PTSD severity and hyperarousal symptomology at all three time points. Psychological distress fully mediated re-experiencing and avoidance symptomology at all three time points. Our results suggest that those with alexithymia are at longitudinal risk of developing more severe PTSD symptomology and experiencing hyperarousal irrespective of temporal proximity to traumatic exposure. Further, vulnerability to the emergence of re-experiencing and avoidance symptomology for those with alexithymia is increased when one experiences greater distress. Our results show that alexithymia is a persistent risk factor for PTSD symptomology.

Abstract
BACKGROUND There is growing support for considering Dance Movement Therapy (DMT) as an effective approach to improving physical and psychological symptoms in eating disorders (ED), but additional evidence is needed. The current study aims to investigate the effectiveness of a DMT intervention for inpatients with ED during an in-hospital rehabilitation program for ED in reducing emotion dysregulation and alexithymia and improving interoceptive awareness. METHODS Forty-nine consecutive inpatient young women with ED (aged between 18 and 34 years) recruited from a clinical center for the rehabilitation of obesity and ED received four group sessions of DMT intervention. All participants completed the Difficulties in Emotion Regulation Scale (DERS), the Toronto Alexithymia Scale (TAS), and the Multidimensional Assessment of Interoceptive Awareness Scale (MAIA) before (Time 0) and after the intervention (Time 1). Paired-sample t-tests were run to assess differences between Time 0 to Time 1. RESULTS From pre-to-post interventions, there was a significant reduction in the means of all of the subscales of DERS, suggesting an improvement in emotion regulation competencies, with the only exception for difficulties in awareness that increased (p = 0.016). We also found a significant reduction in alexithymia, as proved by significant differences in all of the subscales and the total score of TAS (p < 0.001), and significant improvements in interoceptive awareness as suggested by increased scores of the noticing (p = 0.043), emotional awareness (p < 0.001), body listening (p < 0.001), and trusting (p < 0.001) subscales of MAIA. CONCLUSION Overall, our results point towards the efficacy of dance/movement in reducing symptoms of eating disorders. Our findings also suggest that dancing can be considered a useful intervention to increase emotional regulation, reduce alexithymia, and enhance interoceptive awareness.

An exploration of neurobiological and clinical correlates of alexithymia in trauma-exposed police-officers with and without PTSD. Eur J Psychotraumatol 2023; 14:2281187. [PMID: 38154073 PMCID: PMC10990451 DOI: 10.1080/20008066.2023.2281187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 10/25/2023] [Indexed: 12/30/2023] Open
Abstract
Background: Alexithymia, an inability to recognise one's emotions, has been associated with trauma-exposure and posttraumatic stress disorder (PTSD). Previous research suggests involvement of the oxytocin system, and socio-emotional neural processes. However, the paucity of neurobiological research on alexithymia, particularly in trauma-exposed populations, warrants further investigation.Objective: Explore associations between alexithymia, endogenous oxytocin levels, and socio-emotional brain function and morphometry in a trauma-exposed sample.Method: Dutch trauma-exposed police officers with (n = 38; 18 females) and without PTSD (n = 40; 20 females) were included. Alexithymia was assessed with the Toronto Alexithymia Scale (TAS-20). Endogenous salivary oxytocin was assessed during rest, using radioimmunoassay. Amygdala and insula reactivity to socio-emotional stimuli were assessed with functional MRI, amygdala and insula grey matter volume were derived using Freesurfer.Results: Alexithymia was higher in PTSD patients compared to trauma-exposed controls (F(1,70) = 54.031, p < .001). Within PTSD patients, alexithymia was positively associated with PTSD severity (ρ(36) = 0.497, p = .002). Alexithymia was not associated with childhood trauma exposure (β = 0.076, p = .509), police work-related trauma exposure (β = -0.107, p = .355), oxytocin levels (β = -0.164, p = .161), insula (β = -0.170, p = .158) or amygdala (β = -0.175, p = .135) reactivity, or amygdala volume (β = 0.146, p = .209). Insula volume was positively associated with alexithymia (β = 0.222, p = .016), though not significant after multiple testing corrections. Bayesian analyses supported a lack of associations.Conclusions: No convincing neurobiological correlates of alexithymia were observed with any of the markers included in the current study. Yet, the current study confirmed high levels of alexithymia in PTSD patients, independent of trauma-exposure, substantiating alexithymia's relevance in the clinical phenotype of PTSD.

Abstract
BACKGROUND Posttraumatic Stress Disorder is associated with emotion regulation difficulties. However, our understanding of these difficulties has been limited by the reliance of previous work on retrospective trait self-reports, which are unable to capture dynamic, ecologically-valid use of emotion regulation strategies. METHODS To address this issue, this study used an ecological momentary assessment (EMA) design to understand the impact of PTSD on emotion regulation in daily life. We conducted an EMA study in a trauma exposed sample with varying levels of PTSD severity (N = 70; 7 days; 423 observations). RESULTS We found that PTSD severity was linked to greater use of disengagement and perseverative-based strategies to manage negative emotions, regardless of emotional intensity. LIMITATIONS Study design did not allow investigation into the temporal use of emotion regulation strategies and small sample size. CONCLUSIONS This pattern of responding to emotions may interfere with engaging with the fear structure and thus impair emotion processing in current frontline treatments; clinical implications are discussed.

Abstract
BACKGROUND Emotion processing deficits have been identified as a critical transdiagnostic factor that facilitates distress after trauma exposure. Limited skills in identifying and labelling emotional states (i.e. alexithymia) may present on the more automated (less conscious) end of the spectrum of emotional awareness and clarity. Individuals with alexithymia tend to exhibit a disconcordance between subjective experience and autonomic activity (e.g. where high levels of subjective emotional intensity are associated with low physiological arousal), which may exacerbate distress. Although there is a robust link between alexithymia and trauma exposure, no work to date has explored whether alexithymia is associated with emotional response disconcordance among trauma-exposed adults. METHOD Using a validated trauma script paradigm, the present study explored the impact of alexithymia on emotion response concordance [skin conductance (Galvanic Skin Response, GSR) and Total Mood Disturbance (TMD)] among 74 trauma-exposed adults recruited via a posttraumatic stress disorder (PTSD) treatment clinic and student research programme. RESULTS Unlike posttraumatic symptom severity, age, sex, participant type and mood (which showed no effect on emotion response concordance), alexithymia was associated with heightened emotion response disconcordance between GSR and TMD [F(1, 37) = 8.93, p = 0.006], with low GSR being associated with high TMD. Observed effects of the trauma script were entirely accounted for by the interaction with alexithymia, such that those with alexithymia showed a negligible association between subjective and physiological states. CONCLUSION This finding is paramount as it shows that a large proportion of trauma-exposed adults have a divergent emotion engagement profile.

Abstract
Emotional numbing symptoms are a core aspect of posttraumatic stress disorder (PTSD). Since the initial characterization of PTSD in DSM-III, emotional numbing symptoms have been revised and grouped under different symptom clusters (avoidance in DSM-IV, negative alterations in cognitions, and mood in DSM-5). Previous studies have found emotional numbing symptoms to be associated with greater PTSD severity, functional impairment, and worse treatment outcomes. Although considered an important feature, some argue that emotional numbing symptoms may simply reflect the manifestation of major depressive disorder (MDD) symptoms rather than be an inherent part of the PTSD phenotype. Here, we evaluated this question using two different data sets (N1 = 142; CAPS-5, N2 = 163; CAPS-4) of trauma-exposed individuals. First, we evaluated the unique variance of emotional numbing explained by diagnosis as binary variables (i.e., having PTSD, MDD, or both) and the severity of symptoms. Second, we examined the relative importance of each PTSD symptom in relation to emotional numbing symptoms. Results revealed that PTSD had a distinct contribution to the variance explaining emotional numbing symptoms above and beyond MDD. These findings suggest that emotional numbing should not be conceptualized as a simple manifestation of MDD symptoms. Rather, this symptom cluster may be a unique feature of PTSD that should be addressed within the context of trauma.

Abstract
BACKGROUND Multiple published sources from around the world have confirmed an association between an array of adverse childhood experiences (ACEs) and other traumatic events with eating disorders (EDs) and related adverse outcomes, including higher morbidity and mortality. METHODS In keeping with this Special Issue's goals, this narrative review focuses on the ACEs pyramid and its purported mechanisms through which child maltreatment and other forms of violence toward human beings influence the health and well-being of individuals who develop EDs throughout the life span. Relevant literature on posttraumatic stress disorder (PTSD) is highlighted when applicable. RESULTS At every level of the pyramid, it is shown that EDs interact with each of these proclaimed escalating mechanisms in a bidirectional manner that contributes to the predisposition, precipitation and perpetuation of EDs and related medical and psychiatric comorbidities, which then predispose to early death. The levels and their interactions that are discussed include the contribution of generational embodiment (genetics) and historical trauma (epigenetics), social conditions and local context, the ACEs and other traumas themselves, the resultant disrupted neurodevelopment, subsequent social, emotional and cognitive impairment, the adoption of health risk behaviors, and the development of disease, disability and social problems, all resulting in premature mortality by means of fatal complications and/or suicide. CONCLUSIONS The implications of these cascading, evolving, and intertwined perspectives have important implications for the assessment and treatment of EDs using trauma-informed care and trauma-focused integrated treatment approaches. This overview offers multiple opportunities at every level for the palliation and prevention of EDs and other associated trauma-related conditions, including PTSD.

Abstract
While there are a number of recommended first-line interventions for posttraumatic stress disorder (PTSD), treatment efficacy has been less than ideal. Generally, PTSD treatment models explain symptom manifestation via associative learning, treating the individual as a passive organism - acted upon - rather than self as agent. At their core, predictive coding (PC) models introduce the fundamental role of self-conceptualisation and hierarchical processing of one's sensory context in safety learning. This theoretical article outlines how predictive coding models of emotion offer a parsimonious framework to explain PTSD treatment response within a value-based decision-making framework. Our model integrates the predictive coding elements of the perceived: self, world and self-in the world and how they impact upon one or more discrete stages of value-based decision-making: (1) mental representation; (2) emotional valuation; (3) action selection and (4) outcome valuation. We discuss treatment and research implications stemming from our hypotheses.

Acta Psychiatr Scand 2022; 145:628-639.

Abstract
OBJECTIVE Developmental trauma disorder (DTD) is a childhood psychiatric syndrome designed to include sequelae of trauma exposure not fully captured by PTSD. This study aimed to determine whether the assessment of DTD with an independent sample of children in mental health treatment will replicate results from an initial validation study. METHODS The DTD semi-structured interview (DTD-SI) was administered to a convenience sample in six sites in the United States (N = 271 children in mental health care, 8-18 years old, 47% female, 41% Black or Latinx) with measures of trauma history, DSM-IV PTSD, probable DSM-IV psychiatric diagnoses, emotion regulation/dysregulation, internalizing/externalizing problems, and quality of life. Confirmatory factor (CFA) and item response theory (IRT) analyses tested DTD's structure and DTD-SI's information value. Bivariate and multivariate analyses tested DTD's criterion and convergent validity. RESULTS A three-factor solution (i.e., emotion/somatic, attentional/behavioral, and self/relational dysregulation) best fit the data (CFI = 0.91; TLI = 0.89; BIC = 357.17; RMSEA = 0.06; SRMR = 0.05). DTD-SI items were informative across race/ethnicity, gender, and age with three exceptions. Emotion dysregulation was the most informative item at low levels of DTD severity. Non-suicidal self-injury was rare but discriminative in identifying children with high levels of DTD severity. Results supported the criterion and convergent validity of the DTD construct. CONCLUSION This replication provides empirical support for DTD as a construct and potential psychiatric syndrome, and the DTD-SI's validity as a clinical research tool.

Abstract
Functional neurological disorder (FND) symptoms resemble neurological symptoms but are unexplained by disease or injury to the body. Psychological trauma and posttraumatic stress disorder (PTSD) are prevalent among patients with FND. This is a case report of a 64-year-old female who began treatment 2 years after developing PTSD, generalised anxiety disorder, major depressive disorder and agoraphobia following a physical assault. She subsequently developed FND approximately 18 months later. Her FND symptomology was characterised by aphasia and paraplegia. These symptoms usually lasted for a period of hours to days and usually occurred on a weekly basis. She had not previously engaged in psychological therapy due to limited insight into the relationship between her psychological and physiological symptomology. She was treated with Prolonged Exposure for PTSD (PE), and by the last session, she no longer met the diagnostic criteria for either FND or PTSD disorder. PE successfully treated both PTSD and FND. Theoretical understandings of the mechanisms underpinning this improvement are discussed.

Abstract
Women with endometriosis often suffer from genito-pelvic pain. The objective of the present study was to analyze the relationship between cognitive and psycho-emotional factors and sexual functioning of women with endometriosis, comparing women with and without endometriosis. A total of 87 women with endometriosis (EG) and 100 women without endometriosis (CG) completed a socio-demographic questionnaire; the short-form of McGill Pain Questionnaire (SF-MPQ); the Female Sexual Functioning Index (FSFI); the Sexual Distress Scale (SDS); the Symptoms Checklist (SCL-90-R); the Toronto Alexithymia Scale (TAS-20); the Positive and Negative Affects Scale (PANAS); the Sexual Dysfunctional Belief Questionnaire (SDBQ); the Sexual Modes Questionnaire (SMQ); and the Questionnaire of Cognitive Schema Activation in Sexual Context (QCSASC). EG obtained worse scores than CG in SF-MPQ, Pain subscale of FSFI, and SDS. EG reached higher scores than CG on almost all scales of SCL-90-R and lower scores in the “Identifying Feelings” scale of TAS-20. Furthermore, EG reported more negative emotions toward sexuality than CG (PANAS) higher scores on the “Affection Primacy” scale of SDBQ and the “Helpless” sexual cognitive schema of QCSASC than CG. No significant differences were found in SMQ. Sexual health professionals should address psychological, emotional, and cognitive factors since they seem involved in patients’ sexual experiences.

Abstract
Background Posttraumatic stress disorder (PTSD) is a debilitating mental disorder that develops in the aftermath of traumatic life experiences, especially those that occurred in childhood. PTSD is associated with intrusive memories, distressing dreams, dissociative reactions, avoidance of trauma-related stimuli, negative mood and sense of well-being, increased arousal and irritability, and clinically significant distress and impaired functioning. Case Presentation. The following case report presents a 42-year-old male displaying symptoms of PTSD, alexithymia, and depression. Conclusion Untreated alexithymia may aggravate the trauma and cause the development of PTSD and depression.

Beyond Neuropsychiatric Manifestations of Systemic Lupus Erythematosus: Focus on Post-traumatic Stress Disorder and Alexithymia. Curr Rheumatol Rep 2021; 23:52.

Abstract
PURPOSE OF REVIEW To deepen the comprehension of the role of specific psychological conditions in the pathogenesis and in the treatment of systemic lupus erythematosus (SLE). Specifically, the present comprehensive review aims at examining the association between SLE, alexithymia (AT)-a personality construct referring to the inability to identify, describe, and express sensations, emotions, and physical state-and post-traumatic stress disorder (PTSD), to infer potential biological relationships between these psychopathological issues and disease course, and to draw up a research agenda on gray areas of these topics. RECENT FINDINGS Whereas several studies document the presence of neuropsychiatric symptoms in patients with SLE, psychological distress, alexithymia, and post-traumatic manifestations are usually neglected by healthcare professionals and poorly investigated in research contexts. However, the interplay of these aspects, which affect physiologic stress coping mechanisms, potentially plays an important role in SLE pathogenesis. In particular, research documents that cytokine repertoire pattern alteration and hypothalamic-pituitary-adrenal axis impairment leading to inflammation and pain represent the main links between emotional health and immunity. AT and PTSD seem to be common in patients with SLE and account for multiple aspects of SLE-related morbidity. Furthermore, abnormal processing of stressful stimuli as hallmarks of PTSD and AT might promote neuroendocrine dysfunction and dysregulated immunity, thus contributing to the pathogenesis of SLE. A comprehensive, multidisciplinary clinical approach, based on a cooperation between immunologists, rheumatologists, neurologists, and mental health professionals, is crucial to promote patients' global health.
