When a Head Is about to Burst: Attachment Mediates the Relationship Between Childhood Trauma and Migraine

Early-life adversity as a predictor of fibromyalgia syndrome: the central role of perceived stress over endocrine stress indicators

ABSTRACT

This study investigates the associations between early childhood adversities, stress perception, and fibromyalgia syndrome (FMS). Although the interconnection between dysregulated stress systems and FMS is well documented, the interconnection between early adversities and FMS remains less understood. This study explores the relationship of early-life stress and FMS by examining its mediation through perceived stress, and acute and chronic endocrine stress indicators. Stress was assessed using the perceived stress scale, as well as using salivary and hair cortisol as endocrine indicators of acute and chronic stress, respectively. The sample consisted of 99 individuals with FMS and 50 pain-free controls. A structural equation model was used to assess the mediating effects of stress indicators between early adversities and the severity of FMS. Compared with controls, individuals with FMS had notably higher early adversity scores (d = 0.63) and greater occurrence of exposure to adversity (78.8% vs 66%). Structural equation modeling indicated that the influence of early adversities on FMS symptoms is mediated by perceived stress levels, with no direct effect observed. Our findings indicate that early-life adversity is a significant determinant of the development of FMS, with the relationship between these factors mediated by perceived stress rather than by endocrine stress indicators. These results underscore the critical role of stress perception in the development and management of FMS, suggesting that perceived stress may serve as a valuable therapeutic target. Incorporating trauma-informed and stress-targeted care into treatment strategies could significantly improve outcomes for individuals with FMS, emphasizing the importance of addressing psychological factors alongside physical symptoms.

Insecure Attachment, Oxytocinergic System and C-Tactile Fibers: An Integrative and Translational Pathophysiological Model of Fibromyalgia and Central Sensitivity Syndromes

Although the pathophysiology of fibromyalgia syndrome has been better understood in recent decades, a unified model of its pathogenesis and an effective therapeutic approach are still far from being realized. The main aim of this article will be to delve into the fundamental mechanisms of the pathophysiology of fibromyalgia conceptualized as stress intolerance syndrome. Using the biopsychosocial model of chronic pain syndromes, we will describe the potential role of the attachment system, C-tactile fibers, and oxytocinergic system dysfunction in the pathophysiology of fibromyalgia syndrome and other central sensitivity syndromes. At the end of the article, the therapeutic implications of this new global and translational pathophysiological model will be briefly discussed.

Adverse childhood experience is associated with an increased risk of reporting chronic pain in adulthood: a stystematic review and meta-analysis

Background: Adverse childhood experiences (ACEs) have been shown to negatively affect health in adulthood. Estimates of associations between ACEs and chronic painful conditions are lacking.Objectives: This systematic review and meta-analysis aimed to evaluate associations between exposure to ACEs and chronic pain and pain-related disability in adults.Methods: We searched 10 electronic databases from inception to February 2023. We included observational studies assessing associations between direct ACEs (childhood sexual, physical, emotional abuse, or neglect) alone or in combination with indirect ACEs (witnessing domestic violence, household mental illness), and adult chronic pain (≥3 months duration) and pain-related disability (daily activities limited by chronic pain). Pairs of reviewers independently extracted data and assessed study risks of bias. Random-effect models were used to calculate pooled adjusted odds ratios [aOR]. Tau square [T2], 95% prediction intervals [95%PI] and I2 expressed the amount of heterogeneity, and meta-regressions and subgroup meta-analyses investigated sources of heterogeneity (PROSPERO: CRD42020150230).Results: We identified 85 studies including 826,452 adults of which 57 studies were included in meta-analyses. Study quality was generally good or fair (n = 70). The odds of reporting chronic pain in adulthood were significantly higher among individuals exposed to a direct ACE (aOR, 1.45, 95%CI, 1.38-1.53). Individuals reporting childhood physical abuse were significantly more likely to report both chronic pain (aOR, 1.50, 95CI, 1.39-1.64) and pain-related disability (1.46, 95CI, 1.03-2.08) during adulthood. Exposure to any ACEs alone or combined with indirect ACEs significantly increase the odds of adult chronic painful conditions (aOR, 1.53, 95%CI, 1.42-1.65) and pain-related disability (aOR, 1.29; 95%CI, 1.01-1.66). The risk of chronic pain in adulthood significantly increased from one ACE (aOR, 1.29, 95%CI, 1.22-1.37) to four or more ACEs (1.95, 95%CI, 1.73-2.19).Conclusions: Single and cumulative ACEs are significantly associated with reporting of chronic pain and pain-related disability as an adult.

Understanding the gaps in headache and migraine treatment with psychological and behavioral interventions: A narrative review

OBJECTIVE

In this narrative review, we summarize relevant literature pertaining to psychosocial risk factors for headache and migraine progression, current behavioral and psychological treatments, and consider promising treatments.

BACKGROUND

Headache and migraine are common and associated with significant burden and disability. Current treatments targeting psychosocial risk factors show modest outcomes and do not directly address the impact of early life adversity, including the development of maladaptive emotional processing. An intervention that could address these factors and include components of current evidence-based interventions may lead to improved outcomes.

METHODS

We searched PubMed and Google Scholar for articles through December 2022. Search terms included headache, migraine, psychological interventions, behavioral interventions, cognitive-behavioral therapy, mindfulness, psychiatric comorbidities, adverse childhood experiences, trauma, and emotional processing.

RESULTS

Trauma and childhood adversity show a correlation with headache and migraine progression. Developmental adversity and trauma interfere with adaptive emotional processing, which may worsen headache and migraine symptoms, while adaptive ways of experiencing emotions are shown to improve symptoms. Current behavioral and psychological interventions, such as cognitive-behavioral and mindfulness therapies, are effective treatments for headache, but they produce small to medium effect sizes and do not directly address the impact of trauma and emotional conflicts-common factors that contribute to chronicity and disability, especially among certain subpopulations of headache patients such as those with migraine. Thus, there exists a gap in current treatment.

CONCLUSION

There is a gap in headache and migraine treatment for those patients who have a history of trauma, childhood adversity, and maladaptive emotional processing. We suggest that an integrated psychological treatment that includes components of current evidence-based interventions and addresses gaps by focusing on processing trauma-related emotions may improve chronic and debilitating symptoms.

What is the association between childhood adversity and subsequent chronic pain in adulthood? A systematic review

Background

Adverse childhood experiences and chronic pain are complex problems affecting millions of people worldwide, and result in significant healthcare utilisation. Our review aimed to determine known associations between adversity in childhood and chronic pain in adulthood.

Methods

We performed a prospectively registered systematic review (PROSPERO ID: 135625). Six electronic databases (Pubmed, Medline, Cochrane, Scopus, APA PsycNet, Web of Science) were searched from January 1, 2009 until May 30, 2022. Titles and abstracts were screened, and all original research studies examining associations between adverse childhood experiences and chronic pain in adulthood were considered for inclusion. Full texts were reviewed, and a narrative synthesis was used to identify themes from extracted data. Ten percent of studies were dual reviewed to assess inter-rater reliability. Quality assessment of study methodology was undertaken using recognised tools.

Results

Sixty-eight eligible studies describing 196 130 participants were included. Studies covered 15 different types of childhood adversity and 10 different chronic pain diagnoses. Dual reviewed papers had a Cohen's kappa reliability rating of 0.71. Most studies were of retrospective nature and of good quality. There were consistent associations between adverse childhood experiences and chronic pain in adulthood, with a 'dose'-dependent relationship. Poor mental health was found to mediate the detrimental connection between adverse childhood experiences and chronic pain.

Conclusion

A strong association was found between adverse childhood experiences and chronic pain in adulthood. Adverse childhood experiences should be considered in patient assessment, and early intervention to prevent adverse childhood experiences may help reduce the genesis of chronic pain. Further research into assessment and interventions to address adverse childhood experiences is needed.

Attachment anxiety as mediator of the relationship between childhood trauma and personality dysfunction in borderline personality disorder

Insecure attachment has been described as mediating the relationship between childhood trauma and dysfunctional personality traits in different mental disorders. Despite the role insecure attachment and childhood trauma have independently demonstrated to play as determinants of borderline personality disorder, less is known about the mediating mechanisms explaining these associations. For the first time, we assessed adult attachment, childhood trauma and dimensional personality pathology in a sample of outpatients with borderline personality disorder and tested whether the association between childhood trauma and personality dysfunction was at least partially attributable to insecure attachment. The results showed that attachment anxiety fully mediated the relationship between specific types of trauma (emotional abuse and physical neglect) and emotional dysregulation. Further, emotional abuse was both directly associated with dissocial behaviour and indirectly via attachment anxiety (partial mediation). Emotional abuse has been described as an essential environmental factor for the development of borderline personality disorder and emotional dysregulation, on its part, as the core feature of the condition. Our results indicate that attachment anxiety explains the link between these central aspects of borderline personality disorder. Our findings are consistent with previous research and current etiological understanding of the condition and provide support for recommending a careful assessment of childhood traumatic experiences and adult attachment style to gain a more comprehensive insight into the symptoms and its heterogeneity. As a secondary aim, we assessed the effect parental mental illness may have in these mediation models, but no significant influence on childhood trauma, attachment or personality was found.

Effects of childhood trauma on pain-related distress in adults

BACKGROUND

Much of the work in post-musculoskeletal (MSK) trauma and distress has been conducted through frameworks that start from the injury and go forward to better understand the trajectories and predictors of recovery. However, stress-diatheses models suggest that reactions to trauma are shaped by pre-existing experiences of the person more than the parameters of the event itself. In this study, we explore the effects of adverse childhood experiences (ACEs) on traumatic threat appraisal, distress and pain-related functional interference in adulthood.

METHODS

Adult participants with acute, non-catastrophic musculoskeletal trauma completed a battery of questionnaires that included the Adverse Childhood Experiences Questionnaire (ACEQ), the Brief Illness Perceptions Questionnaire (BIPQ), the Traumatic Injuries Distress Scale (TIDS) and the Brief Pain Inventory (BPI). An a priori model was evaluated through path analysis to determine the variance in BPI Interference scores explained through direct or indirect pathways between these variables (ACEQ->BIPQ, BIPQ->TIDS, TIDS->BPI). The analysis was repeated for the sample when disaggregated by sex.

RESULTS

In n = 114, the base model was saturated. After removing non-significant pathways, the ACEQ->BIPQ->TIDS->BPI paths were significant and in the expected direction, explaining 57.1% of variance in acute BPI Interference score. When disaggregated by sex, the effect of ACEs on threat appraisal was only significant in men and not women, although this analysis was exploratory.

CONCLUSIONS

Acute pain-related interference could be predicted by post-traumatic distress and threat appraisal. Threat appraisal could be further predicted through ACEs, more childhood adversities were associated with more threatening appraisal of trauma in adulthood. The disaggregated finding that the effects of childhood adversities were only significant in males requires further exploration.

SIGNIFICANCE

This study explores the potential pathways of the stress-diathesis model while focusing on adverse childhood experiences as a novel contribution to the field of acute post-trauma pain. The findings may inform future research design and interpretation of acute-to-chronic pain risk stratification tools.

The Direct and Indirect Influences of Adverse Childhood Experiences on Physical Health: A Cross-Sectional Study

A growing and significant body of research has documented the close relationship between adverse childhood experiences (ACEs) and health outcomes in adults. Less is known about the complex pathways through which ACEs exert their influence. This article examines the direct relationship between the quality of perceived physical health and childhood adversities. The association between the adversities and the physical health with other psychological and social variables is also analyzed. Data were collected from a sample of 170 subjects, using tools to assess adverse childhood experiences, physical health-related quality of life, socioeconomic vulnerability, emotion regulation, coping strategies, attachment, and social support. Results showed a high frequency of ACEs among the adult population, and the correlation with poor physical health was highly significant. Regression equations to predict physical health also revealed the following as significant variables: wishful thinking, social withdrawal, and cognitive restructuring as coping styles; reappraisal to achieve emotion regulation; fear of rejection or abandonment, and desire for closeness in relation to attachment figures; hardship; and poor financial support. The relationship between the different forms of ACE and social vulnerability identifies the important indirect contribution of childhood adversity to health and socioeconomic conditions in adulthood.
