Abstract
Posttraumatic stress disorder (PTSD) is a significant public health concern, with only a third of patients recovering within a year of treatment. While PTSD often disrupts the sense of body ownership and sense of agency (SA), attention to the SA in trauma has been lacking. This perspective paper explores the loss of the SA in PTSD and its relevance in the development of symptoms. Trauma is viewed as a breakdown of the SA, related to a freeze response, with peritraumatic dissociation increasing the risk of PTSD. Drawing from embodied cognition, we propose an enactive perspective of PTSD, suggesting therapies that restore the SA through direct engagement with the body and environment. We discuss the potential of agency-based therapies and innovative technologies such as gesture sonification, which translates body movements into sounds to enhance the SA. Gesture sonification offers a screen-free, noninvasive approach that could complement existing trauma-focused therapies. We emphasize the need for interdisciplinary collaboration and clinical research to further explore these approaches in preventing and treating PTSD.

Dissociative Experiences, Borderline Personality Disorder Features, and Childhood Trauma: Generating Hypotheses from Data-Driven Network Analysis in an International Sample. J Trauma Dissociation 2024; 25:436-455. [PMID: 38497592 DOI: 10.1080/15299732.2024.2323974] [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: 05/30/2023] [Accepted: 12/22/2023] [Indexed: 03/19/2024]
Abstract
Dissociation is a multifaceted phenomenon that occurs in various mental disorders, including borderline personality disorder (BPD), but also in non-clinical populations. Severity of childhood trauma (abuse, neglect) plays an important role in the development of dissociation and BPD. However, the complex interplay of different dissociative symptoms, BPD features, and self-reported childhood trauma experiences is not yet fully understood. Graph-theoretical network analysis can help to better understand such multivariate interrelations. Objective: This study aimed to investigate associations between self-reported dissociation, BPD features, and childhood trauma experiences using a graph-theoretical approach. Data was collected online via international mental health platforms and research sites. N = 921 individuals (77.4% female) were included; 40% reported pathological levels of dissociation. Variables were assessed with established psychometric scales (Dissociative Experiences Scale; Personality Assessment Inventory Borderline Features Scale; Childhood Trauma Questionnaire) and analyzed within a partial correlation network. Positive bivariate correlations between all variables were found. When accounting for their mutual influence on each other, dissociation was predominantly connected to BPD features with effect sizes between rp = .028 and rp = .126, while still showing a slight unique relationship with physical neglect (rp = .044). Findings suggest close associations between dissociative experiences and BPD features. While childhood trauma plays an important role in the development of dissociation and BPD, its recall may not fully explain their current co-occurrence. Prospective studies are needed to shed more light on causal pathways to better understand which factors contribute to dissociation and its link to BPD (features).

Abstract
To investigate the effects of adverse and protective childhood experiences on symptom improvement in outpatient psychotherapy. We evaluated n = 648 completed outpatient psychodynamic psychotherapies. First, we estimated the rate of symptom improvement for each patient using a two-stage hierarchical linear model. We then calculated the direct and indirect influences of childhood experiences on the improvement rate using a structural equation model. Personality functioning, according to the Operationalized Psychodynamic Diagnosis system, was examined as being a possible mediating factor. The presence of adverse childhood experiences was directly associated with a slower improvement rate in psychotherapy. Moreover, a higher number of adverse childhood experiences was associated with greater impairments in the ability to communicate as one dimension of personality functioning, which in turn was associated with a slower improvement of symptoms. Protective childhood experiences were associated with fewer impairments in specific dimensions of personality functioning, but had no direct effect on the improvement rate. Adverse childhood experiences can directly influence the course of psychotherapy. In addition, the communication dimension of personality functioning appears to be a central mediator on which adverse and protective childhood experiences act antagonistically and can thus indirectly affect the improvement rate in psychotherapy.

Abstract
Background Adverse childhood experiences were previously identified as relevant risk factors for the development of anxiety disorders. Furthermore, anxiety disorders were shown to be associated with impairments of personality functioning. The objective of this study was to investigate adverse and protective childhood experiences as well as personality functioning, as defined by the Operationalized Psychodynamic Diagnosis system, as potential predictors for the speed of recovery during psychotherapy for patients with anxiety disorders. Methods The sample consisted of n = 312 completed psychotherapies. The speed of recovery, defined as symptom abatement over time, was calculated using a two-stage hierarchical linear model. The effects of adverse and protective childhood experiences as well as personality functioning on the speed of recovery during psychotherapy were then examined using a structural equation model. Results The presence of adverse childhood experiences predicted a lower speed of recovery during psychotherapy. In addition, a higher number of adverse childhood experiences was associated with greater impairments in the abilities of perception and regulation as dimensions of personality functioning. A higher number of protective childhood experiences was associated with fewer impairments in the communication and attachment dimensions. Impairments in personality functioning in patients with anxiety disorders did not predict the speed of recovery during psychotherapy. Conclusions Among patients with anxiety disorders, adverse childhood experiences lead to a lower speed of recovery during psychotherapy. Therefore, childhood adversity should be routinely assessed before and thoroughly addressed during psychotherapy in patients with anxiety disorders.

Abstract
Borderline personality disorder (BPD) is characterized by instability in interpersonal, affective, cognitive, self-identity, and behavioral domains. For a BPD diagnosis, individuals must present at least five of nine symptoms, resulting in 256 possible symptom combinations; thus, individuals diagnosed with BPD can differ substantially. Specific symptoms of BPD tend to co-occur, suggesting BPD subgroups. To explore this potential, we analyzed data from 504 participants diagnosed with BPD enrolled in one of three randomized controlled trials conducted at center for Addiction and Mental Health in Toronto, Canada from 2002 to 2018. An exploratory latent class analysis (LCA) was conducted to identify symptom subgroups of BPD. Analyses indicated three latent subgroups. The first group (n = 53) is distinguished by a lack of affective instability and low levels of dissociative symptoms (non-labile type). The second group (n = 279) is characterized by high levels of dissociative and paranoid symptoms but low abandonment fears and identity disturbance (dissociative/paranoid type). The third group (n = 172) is characterized by high efforts to avoid abandonment and interpersonal aggression (interpersonally unstable type). Homogenous symptom subgroups of BPD symptoms exist and may have important implications for how to refine BPD treatment interventions.

Abstract
Dissociation is a complex phenomenon, which occurs in various clinical conditions, including dissociative disorders, (complex) post-traumatic stress disorder (CPTSD, PTSD), and borderline personality disorder (BPD). Traumatic stress is considered an important risk factor, while the etiology of dissociation is still debated. Next to traumatic experiences, temperamental and neurobiological vulnerabilities seem to contribute to the development of dissociation. Stress-related dissociation is a prevalent symptom of BPD, which may interfere with psychosocial functioning and treatment outcome. More research in the field is strongly needed to improve the understanding and management of this complex phenomenon. This article collection brings together research on dissociation and trauma, with a special focus on BPD or sub-clinical expressions of BPD. In this editorial, recent conceptualizations of dissociation and relevant previous research are introduced in order to provide a framework for this novel research.

Abstract
BACKGROUND Borderline personality disorder (BPD) is characterized by altered perception of affective stimuli, including abnormal evaluation of nociceptive input. However, whether or not perceptual alterations are present for its positive counterpart, i.e. pleasant touch (PT), has not yet been examined. METHODS In the present study, we applied standardized PT stimuli to the hands of 25 patients with BPD and 25 healthy controls (HC) and compared their perception. We used the affect-modulated acoustic startle response as a physiological correlate of affective processing. We further explored the effect of PT stimulation on dissociative experiences in BPD. RESULTS Compared to HC, BPD perceived PT as less pleasant and less intense. The effect on perceived valence of touch was large even after controlling for the effect of reduced perceived intensity of touch (ƞ2 = .29). We further found qualitative alterations in touch perception in BPD, who rated the touch as significantly rougher and firmer compared to HC. There was a positive correlation between perceived valence of touch and changes in dissociative experiences in terms of body ownership of the stimulated body part from pre to post stimulation, suggesting that a more negative evaluation of touch is associated with an increase in body-related dissociative experiences, while a positive perception of touch might be related to a reduction of these dissociative experiences. CONCLUSIONS Our results confirm BPD-associated disturbances in the processing of affective somatosensory stimuli and indicate that not only pain perception but also pleasant touch perception is diminished in BPD. We discuss the role of altered touch perception for BPD psychopathology and its potential role for new treatment approaches.

Abstract
Despite high rates of adverse childhood experiences (ACEs) and personality-related disturbances among delinquent juveniles, associations among ACEs, youth personality, and juvenile crime involvement are still unclear. High-risk samples of institutionalized youth are in specific need of a comprehensive assessment of ACEs and personality features in order to broaden the current knowledge on the occurrence and persistence of juvenile crime and to derive implications for prevention and intervention. We examined a heterogeneous high-risk sample of 342 adolescents (35.1% females, 64.9% males) aged between 12 and 18 years (M = 15.74, SD = 1.61 years) living in child-welfare or juvenile justice institutions regarding cumulative ACEs, psychopathic traits, temperament, and clinical personality disorder ratings, and criminal involvement before and up to 10 years after assessment. We found considerable rates of ACEs, although cumulative ACEs did not predict future crime. Latent Profile Analysis based on dimensional measures of psychopathy, temperament, and personality disorders derived six distinct personality profiles, which were differently related to ACEs, personality disturbances, clinical psychopathology, and future delinquency. A socially difficult personality profile was associated with increased risk of future crime, whereas avoidant personality traits appeared protective. Findings indicate that the role of ACEs in the prediction of juvenile delinquency is still not sufficiently clear and that relying on single personality traits alone is insufficient in the explanation of juvenile crime.

Abstract
Dissociation is an involuntary defensive mechanism to protect oneself by avoiding unbearable internal conflicts or overwhelming emotions. Cultivating mindful awareness could allow the development of voluntary processes that can offer part of the self-protective function of dissociation while favoring internal integration processes. The aim of the present study was to explore the effects of a 7-week Mindfulness Oriented Meditation (MOM) training on healthy individuals' self-reported dissociative experience, mindfulness skills and interoceptive awareness. After the training, in comparison to a waiting-list control group (N = 102), the MOM group (N = 110) showed reduced dissociative tendencies (p < .05), increased dispositional mindfulness (p < .001) and increased interoceptive awareness (in the aspects of not-worrying, self-regulation and body listening; p < .001). Moreover, correlational evidence showed that the more MOM participants increased in mindfulness skills after the training the more they reported increased interoceptive awareness and decreased dissociative functioning (p < .05). Mindfulness skills also improved with more home meditation practice executed by MOM participants (p < .05). These findings were attributed to a possible role of mindfulness meditation in enabling the development of volitional processes that afford psychological safety and integration, in contrast with the involuntary nature of dissociation.

Abstract
Dissociative symptoms and suicidality are transdiagnostic features of posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD). The primary objective of this study was to examine associations between dissociation (i.e., depersonalization and derealization) and suicidality (i.e., self-harm and suicide attempts) among individuals with PTSD and BPD. We analyzed data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III; N = 36,309). The Alcohol Use Disorder and Associated Disabilities Interview Schedule for DSM-5 was used to assess lifetime PTSD and BPD. Estimated rates of self-harm among individuals who endorsed dissociation were 15.5%-26.2% for those with PTSD and 13.7%-23.5% for those with BPD, and estimates of suicide attempts among individuals who endorsed dissociation were 34.5%-38.1% for those with PTSD and 28.3%-33.1% for those with BPD. Multiple logistic regressions were conducted to examine the associations between dissociation (derealization, depersonalization, and both) and both self-harm and suicide attempts among respondents with PTSD and BPD. The results indicated that dissociation was associated with self-harm and suicide attempts, especially among individuals with BPD, aORs = 1.39-2.66; however, this association may be driven in part by a third variable, such as other symptoms of PTSD or BPD (e.g., mood disturbance, PTSD or BPD symptom severity). These results may inform risk assessments and targeted interventions for vulnerable individuals with PTSD, BPD, or both aimed at mitigating the risk of self-harm and suicide.

However, possible mediating pathways are still not fully understood. The aim of the present study was to investigate the potential mediating role of body connection, describing the awareness of the relationship of bodily and mental states, for the association between a history of traumatic childhood experiences and BPD core symptomatology. METHODS One-hundred-twelve adult female individuals with BPD and 96 healthy female controls (HC) were included. Impaired emotion regulation, traumatic childhood experiences, and BPD symptomatology were assessed with self-report questionnaires. The Scale of Body Connection was used to assess two dimensions of body connection, that is body awareness, describing attendance to bodily information in daily life and noticing bodily responses to emotions and/or environment and body dissociation, describing a sense of separation from one's own body, due to avoidance or emotional disconnection. Mann-Whitney U tests were employed to test for group differences (BPD vs. HC) on the two SBC subscales and associations with clinical symptoms were analyzed with Spearman correlations. We performed mediation analyses in the BPD group to test the assumption that body connection could act as a mediator between a history of traumatic childhood experiences and emotion dysregulation. RESULTS Individuals with BPD reported significantly lower levels of body awareness and significantly higher levels of body dissociation compared to HC. Body dissociation, traumatic childhood experiences, and emotion dysregulation were significantly positively associated. Further analyses revealed that body dissociation, but not body awareness, significantly and fully mediated the positive relationship between traumatic childhood experiences and impaired emotion regulation in the BPD sample. This mediation survived when trait dissociation, i.e., general dissociative experiences not necessarily related to the body, was statistically controlled for. CONCLUSION Certain dimensions of body connection seem to be disturbed in BPD patients, with body dissociation being an important feature linking a history of traumatic childhood experiences to current deficits in emotion regulation.

Abstract
BACKGROUND This article builds on a previous review (Ford and Courtois, Borderline Personal Disord Emot Dysregul 1:9, 2014) which concluded that complex posttraumatic stress disorder (cPTSD) could not be conceptualized as a sub-type of either PTSD or BPD. Recent research is reviewed that extends and clarifies the still nascent understanding of the relationship between cPTSD and BPD. MAIN BODY The circumscribed formulation of adult cPTSD that has been developed, validated, and included in the 11th Edition of the International Classification of Diseases has spurred research aimed at differentiating cPTSD and BPD both descriptively and empirically. A newly validated Developmental Trauma Disorder (DTD) syndrome for children and adolescents provides a basis for systematic research on the developmental course and origins of adult cPTSD and BPD. This review summarizes recent empirical findings regarding BPD, PTSD, and cPTSD in terms of: (1) prevalence and comorbidity; (2) clinical phenomenology; (3) traumatic antecedents; (4) psychobiology; (5) emotion dysregulation; (6) dissociation; and (7) empirically supported approaches to clinical assessment and psychotherapeutic treatment. CONCLUSION The evidence suggests that PTSD, cPTSD, and BPD are potentially comorbid but distinct syndromes. A hypothesis is advanced to stimulate scientific research and clinical innovation defining and differentiating the disorders, positing that they may represent a continuum paralleling the classic conceptualization of the stress response, with dissociation potentially involved in each disorder.

Abstract
PURPOSE OF REVIEW The aim of this review article is to give an overview over recent experimental neurobiological research on dissociation in borderline personality disorder (BPD), in order to inform clinicians and to stimulate further research. First, we introduce basic definitions and models that conceptualize dissociation from a transdiagnostic perspective. Then, we discuss recent findings in BPD. RECENT FINDINGS Stress-related dissociation is a key symptom of BPD, closely linked to other core domains of the disorder (emotion dysregulation, identity disturbances, and interpersonal disturbances). The understanding of neurobiological correlates of dissociation across different psychiatric disorders (e.g., dissociative disorders, post-traumatic stress disorder) is steadily increasing. At the same time, studies explicitly focusing on dissociation in BPD are still scarce. There is evidence for adverse effects of dissociation on affective-cognitive functioning (e.g., interference inhibition), body perception, and psychotherapeutic treatment response in BPD. On the neural level, increased activity in frontal regions (e.g., inferior frontal gyrus) and temporal areas (e.g., inferior and superior temporal gyrus) during symptom provocation tasks and during resting state was observed, although findings are still diverse and need to be replicated. Conceptual differences and methodological differences in study designs and sample characteristics (e.g., comorbidities, trauma history) hinder a straightforward interpretation and comparison of studies. Given the potentially detrimental impact of dissociation in BPD, more research on the topic is strongly needed to deepen the understanding of this complex clinical condition.

Abstract
Impairments in maintaining a differentiated sense of "self" and "other" are thought to be a central feature of borderline personality disorder (BPD). However, studies directly focusing on self-other distinction (SOD) in BPD are scarce, and these findings have not yet been integrated with novel insights into the neural mechanism involved in SOD. Here, we present a narrative review of recent behavioral and neuroimaging findings focusing on impairments in SOD in BPD. Behavioral findings of SOD at the embodied level provide preliminary evidence for impairments in multisensory integration in BPD. Furthermore, both behavioral and neuroscientific data converge to suggest that SOD impairments in BPD reflect an inability to shift between self and other representations according to task demands. Research also suggests that disruptions in infant-caregiver synchrony may play a role in the development of these impairments. Based on these findings, we present a new, integrative model linking impairments in SOD to reduced neural and behavioral synchrony in BPD. The implications of these findings for future research and clinical interventions are outlined.

Abstract
Opioid use disorder has long been associated with psychiatric symptoms, including dissociative experiences. Medications used to treat opioid use disorder can potentially impact dissociative symptoms, but the existing literature has not explored this. We examined the relationship between dissociative symptoms and opioid use disorder using the Dissociative Experiences Scale (DES). We studied subjects who were taking prescribed methadone, buprenorphine, or naltrexone for opioid use disorder. We gave the DES, the Patient Health Questionairre-9 (PHQ-9), and the PTSD Checklist for DSM-5 (PCL-5) with Criterion A to subjects in three substance use treatment facilities in Ohio. We conducted Analysis of Variance (ANOVA) and Spearman's Rank Correlations to examine associations between the variables and outcomes. We developed three separate multiple linear regression models. We included 116 participants in our exploratory and naturalistic study. The majority of participants were female (51.7%), white (89.5%), ≤ 40 years of age (64.7%), and taking buprenorphine (55%). The average DES score was 16.1 (standard deviation = 14.9) and we considered 80.9% to have low dissociation (score < 30). Approximately 55% (n = 64) of participants were taking prescribed buprenorphine. Approximately 27% (n = 32) were taking prescribed methadone and approximately 18% (n = 21) were taking prescribed naltrexone (oral or extended release). There was a significant association between opioid medication type and log dissociative symptoms (p = .01). Participants taking prescribed buprenorphine had higher mean log dissociation symptom scores (2.7) compared to those taking prescribed methadone (2.2) and prescribed naltrexone (2.1). Log dissociation symptom scores were significantly associated with last use of any opiates (rs = -0.21; p = .02) and time on medication (rs = -0.228; p = .01). Compared to those taking buprenorphine, those taking both methadone (β = -0.26; p = .01) and naltrexone (β = -0.27; p = .006) had significantly lower dissociation scores, controlling for the other variables in the model. Dissociation scores were positively correlated with depression scores (r = 0.45; p < .0001) and with PCL-5 scores (r = 0.51; p < .0001). Our study highlights the importance of diagnosing and monitoring dissociative symptoms in individuals who are taking prescribed medications for opioid use disorder, especially since dissociative symptoms can interfere with substance use treatment.

Abstract
Pathological dissociation is a severe, debilitating and transdiagnostic psychiatric symptom. This review identifies biomarkers of pathological dissociation in a transdiagnostic manner to recommend the most promising research and treatment pathways in support of the precision medicine framework. A total of 205 unique studies that met inclusion criteria were included. Studies were divided into four biomarker categories, namely neuroimaging, psychobiological, psychophysiological and genetic biomarkers. The dorsomedial and dorsolateral prefrontal cortex, bilateral superior frontal regions, (anterior) cingulate, posterior association areas and basal ganglia are identified as neurofunctional biomarkers of pathological dissociation and decreased hippocampal, basal ganglia and thalamic volumes as neurostructural biomarkers. Increased oxytocin and prolactin and decreased tumor necrosis factor alpha (TNF-α) are identified as psychobiological markers. Psychophysiological biomarkers, including blood pressure, heart rate and skin conductance, were inconclusive. For the genetic biomarker category studies related to dissociation were limited and no clear directionality of effect was found to warrant identification of a genetic biomarker. Recommendations for future research pathways and possible clinical applicability are provided.

Abstract
Objective: Nonsuicidal self-injury (NSSI) is a prevalent and clinically significant behavior. There is a substantial association between adverse childhood experiences (ACEs) and NSSI. However, there are no studies investigating the impact of ACEs on NSSI treatment (psychotherapy) outcome. The aim of this secondary analysis of a randomized controlled trial (RCT) on psychotherapy of NSSI was to investigate the relationship between ACEs and treatment outcome in adolescents engaging in NSSI. Method: A sample of 74 adolescent outpatients engaging in repetitive NSSI (incidents on ≥ 5 days within the last 6 months) was recruited for a RCT. ACEs were assessed by the Childhood Experience of Care and Abuse (CECA) interview before treatment onset. Based on the CECA, participants were divided in two groups: with a history of ACEs (n = 30) and without a history of ACEs (n = 44). Frequencies of NSSI, depression, and suicide attempts as well as quality of life were measured at three points in time: before treatment onset (baseline; T0), 4 (T1), and 10 months (T2) after treatment onset. Results: Both participants with and without ACEs were able to reduce the frequency of NSSI significantly [χ2 (1) = 26.72; p < 0.001]. Surprisingly, participants with ACEs reached a significantly greater reduction in NSSI frequency within the past 6 months compared to participants without ACEs [χ2 (1) = 5.08; p = 0.024]. There were also substantial and similar improvements regarding depressive symptoms, suicide attempts and quality of life in both groups. Conclusion: ACEs seem to positively predict treatment response in psychotherapy for adolescent NSSI. This is contrary to prior research suggesting ACE as an unfavorable prognostic factor in the treatment of mental disorders.

Abstract
INTRODUCTION There is currently no general agreement on how to best conceptualize dissociative symptoms and whether they share similar neural underpinnings across dissociative disorders. Neuroimaging data could help elucidate these questions. OBJECTIVES The objective of this review is to summarize empirical evidence for neural aberrations observed in patients suffering from dissociative symptoms. METHODS A systematic literature review was conducted including patient cohorts diagnosed with primary dissociative disorders, post-traumatic stress disorder (PTSD), or borderline personality disorder. RESULTS Results from MRI studies reporting structural (gray matter and white matter) and functional (during resting-state and task-related activation) brain aberrations were extracted and integrated. In total, 33 articles were included of which 10 pertained to voxel-based morphology, 2 to diffusion tensor imaging, 10 to resting-state fMRI, and 11 to task-related fMRI. Overall findings indicated aberrations spread across diverse brain regions, especially in the temporal and frontal cortices. Patients with dissociative identity disorder and with dissociative PTSD showed more overlap in brain activation than each group showed with depersonalization/derealization disorder. CONCLUSION In conjunction, the results indicate that dissociative processing cannot be localized to a few distinctive brain regions but rather corresponds to differential neural signatures depending on the symptom constellation.

Abstract
BACKGROUND From a developmental and pathogenic perspective, child maltreatment is strongly linked to later dissociative symptoms, as ultimate forms of human response to chronic stress. The present study aimed to investigate the mediating role of early maladaptive schemas (EMSs) in the relationship between child maltreatment and dissociation among patients with borderline personality disorder (BPD). METHODS In this cross-sectional study, a total of 152 BPD patients (men: 52%; women: 48%) with an average age of 29.64 years (standard deviation (SD) = 7.29, range = 18-47) were selected by systematic random sampling from the patients who referred to Baharan psychiatric hospital in Zahedan, Iran, with the sampling interval of 3. The Childhood Trauma Questionnaire-Short Form, Dissociative Experiences Scale, and Young Schema Questionnaire-Short Form 3 were used to assess the patients. Data were analyzed using SPSS v25 software, and the statistical significance level was set at p < 0.05. RESULTS four main findings were obtained from the present study: (1) Heterogeneity of the levels of dissociation (LOD) in BPD patients; (2) The predicting roles of emotional neglect (EN), vulnerability to harm, and defectiveness/shame schemas in the total DES scores; (3) The vague role of childhood sexual abuse (SA) in developing dissociative symptoms; and (4) The mediating role of the core schemas of vulnerability to harm (β = 0.28, 95% confidence interval (CI): 0.04, 0.61) and defectiveness/shame (β = 0.21, 95% CI: 0.008, 0.45) in the relationship between EN and dissociation. CONCLUSIONS Regarding the heterogeneity of LOD and its crucial role in the successful treatment of BPD patients, it is highly essential to evaluate the present-state dissociation of the patient during the diagnosis process and provide effective interventions to reduce it. The obtained results highlighted the potential role of schema therapy in reducing dissociative responses to emotional stimuli (based on EN), vulnerability to harm, and defectiveness/shame. Nevertheless, psychopathology of dissociation among BPD patients should be further investigated in depth.

Abstract
BACKGROUND There is evidence that incarcerated people show higher rates of symptoms of psychopathology. In the present study, we assessed male Iranian incarcerated people with borderline personality disorders (BPD) and investigated the occurrence of past and current trauma and their associations with dissociative experiences. METHODS A total of 69 male Iranian incarcerated people (mean age: 33.76 years) diagnosed with PBD completed questionnaires covering sociodemographic information, dissociative experiences, and past and current traumatic events. RESULTS Participants reporting the occurrence of childhood trauma also reported the occurrence of adulthood trauma. Dissociation and adulthood trauma were associated in a U-shaped, non-linear fashion: Low and high adulthood trauma were associated with higher dissociation. Younger age, the presence of childhood trauma, and being single or divorced predicted adulthood trauma. CONCLUSION The pattern of results suggests that both childhood and adulthood trauma are highly prevalent among male incarcerated people, while the association between adulthood trauma and dissociation appeared to be more complex. When treating male incarcerated people, a complex interplay between past and current traumas and dissociation should be considered.

Abstract
AbstractBackgroundPsychosis-like experiences (PEs) are common in patients with non-psychotic disorders. Several factors predict reporting of PEs in mood disorders, including mood-associated cognitive biases, anxiety and features of borderline personality disorder (BPD). Childhood traumatic experiences (CEs), often reported by patients with BPD, are an important risk factor for mental disorders. We hypothesized that features of BPD may mediate the relationship between CEs and PEs. In this study, we investigated the relationships between self-reported PEs, CEs and features of BPD in patients with mood disorders.MethodsAs part of the Helsinki University Psychiatric Consortium study, McLean Screening Instrument (MSI), Community Assessment of Psychic Experiences (CAPE-42) and Trauma and Distress Scale (TADS) were filled in by patients with mood disorders (n = 282) in psychiatric care. Correlation coefficients between total scores of scales and their dimensions were estimated, multiple regression and mediation analyses were conducted.ResultsTotal scores of MSI correlated strongly with scores of the CAPE-42 dimension “frequency of positive symptoms” (rho = 0.56; p ≤ 0.001) and moderately with scores of TADS (rho = 0.4; p ≤ 0.001). Total score of MSI and its dimension “cognitive symptoms”, including identity disturbance, distrustfulness and dissociative symptoms, fully mediated the relation between TADS and CAPE-42. Each cognitive symptom showed a partial mediating role (dissociative symptoms 43% (CI = 25–74%); identity disturbance 40% (CI = 30-73%); distrustfulness 18% (CI = 12-50%)).ConclusionsSelf-reported cognitive-perceptual symptoms of BPD fully mediate, while affective, behavioural and interpersonal symptoms only partially mediate the relationships between CEs and PEs. Recognition of co-morbid features of BPD in patients with mood disorders reporting PEs is essential.

Abstract
Post-traumatic stress disorder (PTSD), a diagnosis that may follow the experience of trauma, has multiple symptomatic phenotypes. Generally, individuals with PTSD display symptoms of hyperarousal and of hyperemotionality in the presence of fearful stimuli. A subset of individuals with PTSD; however, elicit dissociative symptomatology (i.e., depersonalization, derealization) in the wake of a perceived threat. This pattern of response characterizes the dissociative subtype of the disorder, which is often associated with emotional numbing and hypoarousal. Both symptomatic phenotypes exhibit attentional threat biases, where threat stimuli are processed preferentially leading to a hypervigilant state that is thought to promote defensive behaviors during threat processing. Accordingly, PTSD and its dissociative subtype are thought to differ in their proclivity to elicit active (i.e., fight, flight) versus passive (i.e., tonic immobility, emotional shutdown) defensive responses, which are characterized by the increased and the decreased expression of the sympathetic nervous system, respectively. Moreover, active and passive defenses are accompanied by primarily endocannabinoid- and opioid-mediated analgesics, respectively. Through critical review of the literature, we apply the defense cascade model to better understand the pathological presentation of defensive responses in PTSD with a focus on the functioning of lower-level midbrain and extended brainstem systems.

Abstract
Three and a half decades of research on posttraumatic stress disorder (PTSD) has produced substantial knowledge on the pathobiology of this frequent and debilitating disease. However, despite all research efforts, so far no drug that has specifically targeted PTSD core symptoms progressed to clinical use. Instead, although not overly efficient, serotonin re-uptake inhibitors continue to be considered the gold standard of PTSD pharmacotherapy. The psychotherapeutic treatment and symptom-oriented drug therapy options available for PTSD treatment today show some efficacy, although not in all PTSD patients, in particular not in a substantial percent of those suffering from the detrimental sequelae of repeated childhood trauma or in veterans with combat related PTSD. PTSD has this in common with other psychiatric disorders - in particular effective treatment for incapacitating conditions such as resistant major depression, chronic schizophrenia, and frequently relapsing obsessive-compulsive disorder as well as dementia has not yet been developed through modern neuropsychiatric research.In response to this conundrum, the National Institute of Mental Health launched the Research Domain Criteria (RDoC) framework which aims to leave diagnosis-oriented psychiatric research behind and to move on to the use of research domains overarching the traditional diagnosis systems. To the best of our knowledge, the paper at hand is the first that has systematically assessed the utility of the RDoC system for PTSD research. Here, we review core findings in neurobiological PTSD research and match them to the RDoC research domains and units of analysis. Our synthesis reveals that several core findings in PTSD such as amygdala overactivity have been linked to all RDoC domains without further specification of their distinct role in the pathophysiological pathways associated with these domains. This circumstance indicates that the elucidation of the cellular and molecular processes ultimately decisive for regulation of psychic processes and for the expression of psychopathological symptoms is still grossly incomplete. All in all, we find the RDoC research domains to be useful but not sufficient for PTSD research. Hence, we suggest adding two novel domains, namely stress and emotional regulation and maintenance of consciousness. As both of these domains play a role in various if not in all psychiatric diseases, we judge them to be useful not only for PTSD research but also for psychiatric research in general.

Abstract
Recent research has highlighted the contribution of interoceptive signals to different aspects of bodily self-consciousness (BSC) by means of the cardio-visual stimulation - i.e. perceiving a pulsing stimulus in synchrony with one's own heart. Here, for the first time, we investigate the effects of individual heartbeats on a critical feature of BSC, namely the recognition of one's own face. Across two studies, we explored the cardiac-timing effects on a classic self-face recognition task. In Study 1, participants saw morphed faces that contained different percentages of the self-face and that of another unfamiliar individual. Study 2 used a similar design, albeit participants saw morphed faces of the self-face and that of a familiar other to provide a better control of self-familiarity. Results from both studies consistently revealed that the cortical processing of cardiac afferent signals conveyed by the firing of arterial baroreceptors affects the speed, but not the accuracy, of self-face recognition, when a single picture is presented during cardiac systole, as compared to diastole. This effect is stronger and more stable for stimuli with more self-cues than other-cues and for 'ambiguous' stimuli - i.e. at the individual point of subjective equality. Results from Study 2 also revealed that cardiac effects on the speed of self-face recognition cannot be explained simply on the basis of the imbalanced familiarity between the self's and other's faces used. The present findings highlight the interoceptive contributions to self-recognition and may be expand our understanding of pathological disturbances of self-experience.

Abstract
The dissociative subtype of posttraumatic stress disorder (PTSD) was officially introduced in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). In accordance with this new classification, prior studies using Latent Class Analysis (LCA) empirically identified a subgroup of patients that were characterized by a high severity of dissociative symptoms. Despite the high prevalence of PTSD in patients with substance use disorders (SUD), however, no LCA studies on the dissociative subtype of PTSD exist in this population so far. Therefore, the current study aimed to identify subgroups of patients with different symptom and exposure profiles in patients with SUD and PTSD. It was assumed that one symptom and exposure profile could be identified that would be characterized by higher dissociative symptoms, higher additional psychopathology and a higher burden of childhood trauma, as compared to other subgroups. In N = 258 female patients with SUD and PTSD, clinical characteristics of dissociative symptoms, PTSD severity, borderline personality disorder (BPD), depression, childhood trauma and substance abuse were assessed. To identify symptom and exposure profiles, Latent Class Analysis was applied. A three-class solution indicated the best model fit to our data. One class was characterized by a high probability of dissociative symptoms (D-PTSD class), whereas the other two classes were characterized by lower probabilities of dissociative symptoms. The D-PTSD class encompassed 18.7% of the patients. In accordance with our hypothesis, the D-PTSD class showed higher probabilities of PTSD severity, borderline personality disorder symptoms, depressive symptoms, childhood emotional and sexual abuse, childhood emotional neglect, and drug abuse. Our results indicate that the dissociative subtype of PTSD could also be identified in a sample of female patients with SUD. Patients with SUD and PTSD characterized by the dissociative subtype showed more severe psychopathological symptoms than the remaining patients, indicating enhanced clinical needs for this vulnerable group.

Abstract
Objective To overview the phenomenology, etiology, assessment, and treatment of psychotic-like symptoms in trauma-related disorders focusing on the proposed role of temporal lobe dysfunction. Method We describe the literature pertaining to (i) psychotic-like symptoms and temporal lobe dysfunction in trauma-related disorders and (ii) psychological testing profiles in trauma-related disorders. We define trauma-related disorders as borderline personality disorder, post-traumatic stress disorder, and the dissociative disorders. Our search terms were dissociative disorders, temporal lobe, trauma, post-traumatic stress disorder, borderline personality disorder, psychosis, and malingering. Results Trauma-related psychotic-like symptoms are common and can differ in phenomenology from primary psychotic symptoms. Hallucinations consist of auditory and nonauditory content that may or may not relate to traumatic content. Child voices are highly suggestive of complex dissociative disorders. Critically, not only do these symptoms resemble those seen in temporal lobe epilepsy, but the temporal lobe is implicated in trauma-related disorders, thus providing a plausible neurobiological explanation. Despite such evidence, these symptoms are frequently considered atypical and misdiagnosed. Indeed, common structured psychological assessment tools categorize these symptoms as possible indicators of invalid testing profiles. Conclusion Psychotic-like symptoms are common in trauma-related disorders, may be related to temporal lobe dysfunction, and are frequently misinterpreted. This may lead to ineffective treatment and inappropriate determinations of malingering in the forensic system.

Abstract
Purpose of Review In this article, we aim to give an overview over recent neuroimaging research on dissociation in borderline personality disorder (BPD). Stress-related dissociation is highly prevalent in BPD, while so far only little is known about its neural underpinnings. Recent Findings Based on research in depersonalization and the dissociative subtype of posttraumatic stress disorder, it has been proposed that dissociation involves alterations in a cortico-limbic network. In BPD, neuroimaging research explicitly focusing on dissociation is still scarce. Summary Functional neuroimaging studies have provided preliminary evidence for an altered recruitment and interplay of fronto-limbic regions (amygdala, anterior cingulate, inferior frontal gyrus, medial and dorsolateral prefrontal cortices) and temporoparietal areas (superior temporal gyrus, inferior parietal lobule, fusiform gyrus), which may underlie disrupted affective-cognitive processing during dissociation in BPD. More neuroimaging research with larger samples, clinical control groups, and repeated measurements is needed to deepen the understanding of dissociation in BPD.

Abstract
OBJECTIVE To examine the two constitutes of cortical volume (CV), that is, cortical thickness (CT) and surface area (SA), in individuals with dissociative identity disorder (DID) with the view of gaining important novel insights into the underlying neurobiological mechanisms mediating DID. METHODS This study included 32 female patients with DID and 43 matched healthy controls. Between-group differences in CV, thickness, and SA, the degree of spatial overlap between differences in CT and SA, and their relative contribution to differences in regional CV were assessed using a novel spatially unbiased vertex-wise approach. Whole-brain correlation analyses were performed between measures of cortical anatomy and dissociative symptoms and traumatization. RESULTS Individuals with DID differed from controls in CV, CT, and SA, with significantly decreased CT in the insula, anterior cingulate, and parietal regions and reduced cortical SA in temporal and orbitofrontal cortices. Abnormalities in CT and SA shared only about 3% of all significantly different cerebral surface locations and involved distinct contributions to the abnormality of CV in DID. Significant negative associations between abnormal brain morphology (SA and CV) and dissociative symptoms and early childhood traumatization (0 and 3 years of age) were found. CONCLUSIONS In DID, neuroanatomical areas with decreased CT and SA are in different locations in the brain. As CT and SA have distinct genetic and developmental origins, our findings may indicate that different neurobiological mechanisms and environmental factors impact on cortical morphology in DID, such as early childhood traumatization.

Abstract
Affective hyper-reactivity and impaired cognitive control of emotional material are core features of borderline personality disorder (BPD). A high percentage of individuals with BPD experience stress-related dissociation, including emotional numbing and memory disruptions. So far little is known about how dissociation influences the neural processing of emotional material in the context of a working memory task in BPD. We aimed to investigate whole-brain activity and amygdala functional connectivity (FC) during an Emotional Working Memory Task (EWMT) after dissociation induction in un-medicated BPD patients compared to healthy controls (HC). Using script-driven imagery, dissociation was induced in 17 patients ('BPD_D'), while 12 patients ('BPD_N') and 18 HC were exposed to neutral scripts during fMRI. Afterwards, participants performed the EWMT with neutral vs. negative IAPS pictures vs. no distractors. Main outcome measures were behavioral performance (reaction times, errors) and whole-brain activity during the EWMT. Psychophysiological interaction analysis was used to examine amygdala connectivity during emotional distraction. BPD patients after dissociation induction showed overall WM impairments, a deactivation in bilateral amygdala, and lower activity in left cuneus, lingual gyrus, and posterior cingulate than BPD_N, along with stronger left inferior frontal gyrus activity than HC. Furthermore, reduced amygdala FC with fusiform gyrus and stronger amygdala FC with right middle/superior temporal gyrus and left inferior parietal lobule was observed in BPD_D. Findings suggest that dissociation affects reactivity to emotionally salient material and WM. Altered activity in areas associated with emotion processing, memory, and self-referential processes may contribute to dissociative states in BPD.

Abstract
PURPOSE Dissociation is a common symptom in Borderline Personality disorder (BPD) and its consideration is important for the therapeutic outcome. The aim of this cross-sectional study was to scrutinize the co-occurrence of BPD symptoms and dissociative experiences. In particular, we were interested in the occurrence of specific symptom clusters characterizing qualitatively different patient groups in a clinical sample of BPD patients. BASIC PROCEDURES We analyzed the data of 103 patients in a specialized acute inpatient care crisis intervention unit. Measures were the Borderline Symptom List (BSL-95), a German adaption of the Dissociative Experience Scale (FDS), and the Symptom Checklist SCL-90-R. We applied a Latent Profile Analysis (LPA) using the subscales of BSL-95 and FDS to investigate the existence of distinct latent classes of symptom profiles. Afterwards, we related the obtained profiles to other clinical and demographic characteristics. MAIN FINDINGS Dissociative experiences of moderate to severe intensity were common among patients with BPD. LPA revealed that a model of three classes fitted the data best: one class was characterized by co-occurrence of severe borderline symptoms and frequent dissociative experiences, one class showed low symptom burden in both measures, and one class showed considerable borderline symptoms but only moderate dissociative experiences. The classes were closely related to the severity of other self-rated psychological problems and showed significantly different occurrences of stress-related comorbid disorders. PRINCIPAL CONCLUSIONS The results underline that dissociation is an important factor in many (but not all) BPD patients. This should be addressed by increased attention to dissociative symptoms in the diagnostic process and the adjustment of treatment plans.

Abstract
Symptoms of dissociation, including dissociative amnesia, depersonalization, and derealization, commonly develop in individuals subject to chronic and repeated trauma during development. This includes the trauma of environmental inability to facilitate development of adequate cognitive strategies for coping with strong negative emotions. Dissociation likely involves dysregulated balance of prefrontal inhibition of limbic structures and inadequate regulation of attentional bias by both prefrontal and limbic systems. There is currently no established psychopharmacologic treatment for dissociative symptoms. Here the case of a woman with severe dissociative symptoms that were markedly improved with the administration of mixed amphetamine salts is discussed. Potential neurobiologic mechanisms for dissociative symptom improvement with psychostimulants are discussed.

Abstract
Emotion instability in borderline personality disorder (BPD) has been associated with an impaired fronto-limbic inhibitory network. However, functional connectivity (FC) underlying altered emotion regulation in BPD has yet to be established. Here, we used resting-state fMRI to investigate enduring effects of effortful emotion regulation on the amygdala intrinsic FC in BPD. In this multicenter study, resting-state fMRI was acquired before and after an emotion regulation task in 48 BPD patients and 39 non-patient comparison individuals. The bilateral amygdalae were used as a seed in the whole-brain FC analysis and two-way mixed ANOVA to test whether BPD patients exhibited weaker post-task increase in the amygdala intrinsic FC with the prefrontal cortex (PFC), compared to non-patients. Subsequently, we explored whether the results are common for personality disorders characterized by emotional problems, using additional data of 21 cluster-C personality disorder patients. In contrast to non-patients, BPD patients failed to show increased post-task amygdala resting-state FC with the medial, dorsolateral, ventrolateral PFC, and superior temporal gyrus, but surprisingly exhibited decreased FC with the posterior cingulate cortex and increased FC with the superior parietal lobule. In BPD patients, the emotion regulation task failed to increase resting-state amygdala FC with brain regions essential for effortful emotion regulation, which suggests: (a) altered cognitive control typically used to indirectly alleviate distress by reinterpreting the meaning of emotional stimuli; (b) impaired direct regulation of emotional responses, which might be common for personality disorders;

Abstract
BACKGROUND Functional neurological disorder (FND) is an elusive disorder characterized by unexplained neurological symptoms alongside aberrant cognitive processing and negative affect, often associated with amygdala reactivity. METHODS We examined the effect of negative conditioning on cognitive function and amygdala reactivity in 25 FND patients and 20 healthy volunteers (HV). Participants were first conditioned to stimuli paired with negative affective or neutral (CS +/CS -) information. During functional MRI, subjects then performed an instrumental associative learning task to avoid monetary losses in the context of the previously conditioned stimuli. We expected that FND patients would be better at learning to avoid losses when faced with negatively conditioned stimuli (increased harm avoidance). Multi-echo resting state fMRI was also collected from the same subjects and a robust denoising method was employed, important for removing motion and physiological artifacts. RESULTS FND subjects were more sensitive to the negative CS + compared to HV, demonstrated by a reinforcement learning model. Contrary to expectation, FND patients were generally more impaired at learning to avoid losses under both contexts (CS +/CS -), persisting to choose the option that resulted in a negative outcome demonstrated by both behavioural and computational analyses. FND patients showed enhanced amygdala but reduced dorsolateral prefrontal cortex responses when they received negative feedback. Patients also had increased resting state functional connectivity between these two regions. CONCLUSIONS FND patients had impaired instrumental avoidance learning, findings that parallel previous observations of impaired action-outcome binding. FND patients further show enhanced behavioural and neural sensitivity to negative information. However, this did not translate to improved avoidance learning. Put together, our findings do not support the theory of harm avoidance in FND. We highlight a potential mechanism by which negative contexts interfere with adaptive behaviours in this under-explored disorder.

Abstract
OBJECTIVE To consider the use of the diagnostic category 'complex posttraumatic stress disorder' (c-PTSD) as detailed in the forthcoming ICD-11 classification system as a less stigmatising, more clinically useful term, instead of the current DSM-5 defined condition of 'borderline personality disorder' (BPD). CONCLUSIONS Trauma, in its broadest definition, plays a key role in the development of both c-PTSD and BPD. Given this current lack of differentiation between these conditions, and the high stigma faced by people with BPD, it seems reasonable to consider using the diagnostic term 'complex posttraumatic stress disorder' to decrease stigma and provide a trauma-informed approach for BPD patients.

Abstract
Several authors have studied dissociation within the borderline personality disorder (BPD) population and postulated 3 dissociative subgroups. Conversely, other authors suggest that dissociation may play a central role in the development of trauma-related disorders and specifically in BPD. Nevertheless, the role of dissociation in BPD seems to be controversial. Our aim is to perform a meta-analytic review of the literature to evaluate the extent of dissociation in BPD compared to other psychopathological disorders to clarify its role in this specific condition. Ten eligible studies resulted in a total of 2,035 subjects. Results show that levels of dissociation are higher in BPD than in other psychiatric disorders in general, although this difference is moderate and the heterogeneity of effect sizes is large. In particular, individuals with BPD seem to show higher levels of dissociation than those with several psychiatric and personality disorders but not dissociative disorders or posttraumatic stress disorder. These findings support the fact that dissociation is not specifically a core feature of BPD and, in addition, sustain the existence of a continuum of severity within the psychiatric population. Nevertheless, the current work has several limitations related to the paucity of studies included, the heterogeneity of control groups, their clear definition, and the statistical robustness of the results. In addition, our conclusions require future research in order to explain the role of different forms of dissociation and their etiological factors among the psychiatric population. Eventually, we invite clinicians and researchers to systematically evaluate dissociation in order to reach a better diagnosis for a more specific treatment indication.

Relationships between self-reported childhood traumatic experiences, attachment style, neuroticism and features of borderline personality disorders in patients with mood disorders.

Abstract
BACKGROUND Co-occurring borderline personality disorder (BPD) features have a marked impact on treatment of patients with mood disorders. Overall, high neuroticism, childhood traumatic experiences (TEs) and insecure attachment are plausible aetiological factors for BPD. However, their relationship with BPD features specifically among patients with mood disorders remains unclear. We investigated these relationships among unipolar and bipolar mood disorder patients. METHODS As part of the Helsinki University Psychiatric Consortium study, the McLean Screening Instrument (MSI), the Experiences in Close Relationships-Revised (ECR-R), the Short Five (S5) and the Trauma and Distress Scale (TADS) were filled in by patients with mood disorders (n=282) in psychiatric care. Correlation coefficients between total scores of scales and their dimensions were estimated, and multivariate regression (MRA) and mediation analyses were conducted. RESULTS Spearman's correlations were strong (rho=0.58; p<0.001) between total scores of MSI and S5 Neuroticism and moderate (rho=0.42; p<0.001) between MSI and TADS as well as between MSI and ECR-R Attachment Anxiety. In MRA, young age, S5 Neuroticism and TADS predicted scores of MSI (p<0.001). ECR-R Attachment Anxiety mediated 33% (CI=17-53%) of the relationships between TADS and MSI. LIMITATIONS Cross-sectional questionnaire study. CONCLUSIONS We found moderately strong correlations between self-reported BPD features and concurrent high neuroticism, reported childhood traumatic experiences and Attachment Anxiety also among patients with mood disorders. Independent predictors for BPD features include young age, frequency of childhood traumatic experiences and high neuroticism. Insecure attachment may partially mediate the relationship between childhood traumatic experiences and borderline features among mood disorder patients.

Abstract
BACKGROUND Little is known about the frontolimbic abnormalities thought to underlie borderline personality disorder (BPD). We endeavoured to study regional responses, as well as their connectivity and habituation during emotion processing. METHODS 14 BPD patients and 14 normal female controls (NC) controlled for menstrual phase underwent emotion-induction during an fMRI task using standardised images in a block design. We then performed psychophysiological interaction (PPI) analysis to investigate functional connectivity. RESULTS BPD patients reported more disgust in questionnaires compared to controls. Relative to NC, they showed reduced left amygdala and increased dorsolateral prefrontal cortex (dlPFC) activation to all emotions collapsed versus neutral. Habituation of ventral striatal activity to repeated emotional stimuli was observed in controls but not in BPD. Finally, in the context of disgust (but not other emotions) versus neutral, BPD patients displayed enhanced left amygdala coupling with the dlPFC and ventral striatum. LIMITATIONS Strict inclusion criteria reduced the sample size. CONCLUSIONS In summary, BPD showed abnormal patterns of activation, habituation and connectivity in regions linked to emotion regulation. Amygdala deactivation may be mediated by abnormal top-down regulatory control from the dorsolateral prefrontal cortex. Aberrant emotion processing may play a unique role in the pathophysiology of BPD.

Abstract
Dissociation involves disruptions of usually integrated functions of consciousness, perception, memory, identity, and affect (e.g., depersonalization, derealization, numbing, amnesia, and analgesia). While the precise neurobiological underpinnings of dissociation remain elusive, neuroimaging studies in disorders, characterized by high dissociation (e.g., depersonalization/derealization disorder (DDD), dissociative identity disorder (DID), dissociative subtype of posttraumatic stress disorder (D-PTSD)), have provided valuable insight into brain alterations possibly underlying dissociation. Neuroimaging studies in borderline personality disorder (BPD), investigating links between altered brain function/structure and dissociation, are still relatively rare. In this article, we provide an overview of neurobiological models of dissociation, primarily based on research in DDD, DID, and D-PTSD. Based on this background, we review recent neuroimaging studies on associations between dissociation and altered brain function and structure in BPD. These studies are discussed in the context of earlier findings regarding methodological differences and limitations and concerning possible implications for future research and the clinical setting.

Abstract
Swift switching, along with atypical ability on updating and inhibition, has been found in non-clinical dissociators. However, whether swift switching is a cognitive endophenotype that intertwines with traumatisation and pathological dissociation remains unknown. Unspecified acute psychiatric patients were recruited to verify a hypothesis that pathological dissociation is associated with swift switching and traumatisation may explain this relationship. Behavioural measures of intellectual function and three executive functions including updating, switching and inhibition were administered, together with standardised scales to evaluate pathological dissociation and traumatisation. Our results showed superior control ability on switching and updating in inpatients who displayed more symptoms of pathological dissociation. When all three executive functions were entered as predictors, in addition to intellectual quotient and demographic variables to regress upon pathological dissociation, switching rather than updating remained the significant predictor. Importantly, the relationship between pathological dissociation and switching became non-significant when the effect of childhood trauma were controlled. The results support a trauma-related switching hypothesis which postulates swift switching as a cognitive endophenotype of pathological dissociation; traumatisation in childhood may explain the importance of swift switching.

Abstract
In this paper, I argue that the pervasive assignment of the psychiatric diagnosis of borderline personality disorder (BPD) to female survivors of chronic childhood trauma pathologizes their life experiences, behavior, and survival strategies. I build on Nancy Potter's argument that diagnostic and clinical practices related to BPD are significantly informed by cultural and gender norms. I maintain that clinicians and society need to appreciate better the life experiences, social situations, and moral virtues of survivors. I conclude with a consideration of Judith Herman's alternate diagnosis of complex post-traumatic stress disorder (C-PTSD) and discuss various limitations of current mental health treatment of survivors.

Abstract
This paper presents an analysis of dream-reality confusion (DRC) in relation to the characteristics of borderline personality disorder (BPD), based on research findings and theoretical considerations. It is hypothesized that people with BPD are more likely to experience DRC compared to people in non-clinical population. Several variables related to this hypothesis were identified through a theoretical analysis of the scientific literature. Sleep disturbances: problems with sleep are found in 15–95.5% of people with BPD (Hafizi, 2013), and unstable sleep and wake cycles, which occur in BPD (Fleischer et al., 2012), are linked to DRC. Dissociation: nearly two-thirds of people with BPD experience dissociative symptoms (Korzekwa and Pain, 2009) and dissociative symptoms are correlated with a fantasy proneness; both dissociative symptoms and fantasy proneness are related to DRC (Giesbrecht and Merckelbach, 2006). Negative dream content: People with BPD have nightmares more often than other people (Semiz et al., 2008); dreams that are more likely to be confused with reality tend to be more realistic and unpleasant, and are reflected in waking behavior (Rassin et al., 2001). Cognitive disturbances: Many BPD patients experience various cognitive disturbances, including problems with reality testing (Fiqueierdo, 2006; Mosquera et al., 2011), which can foster DRC. Thin boundaries: People with thin boundaries are more prone to DRC than people with thick boundaries, and people with BPD tend to have thin boundaries (Hartmann, 2011). The theoretical analysis on the basis of these findings suggests that people who suffer from BPD may be more susceptible to confusing dream content with actual waking events.

Abstract
Dissociation, particularly the shutting down of sensory, motor and speech systems, has been proposed to emerge in susceptible individuals as a defensive response to traumatic stress. In contrast, other individuals show signs of hyperarousal to acute threat. A key question is whether exposure to particular types of stressful events during specific stages of development can program an individual to have a strong dissociative response to subsequent stressors. Vulnerability to ongoing shutdown dissociation was assessed in 75 inpatients (46M/29F, M = 31±10 years old) with schizophrenia spectrum disorder and related to number of traumatic events experienced or witnessed during childhood or adulthood. The Maltreatment and Abuse Chronology of Exposure (MACE) scale was used to collect retrospective recall of exposure to ten types of maltreatment during each year of childhood. Severity of shutdown dissociation was related to number of childhood but not adult traumatic events. Random forest regression with conditional trees indicated that type and timing of childhood maltreatment could predictably account for 31% of the variance (p < 0.003) in shutdown dissociation, with peak vulnerability occurring at 13-14 years of age and with exposure to emotional neglect followed by various forms of emotional abuse. These findings suggest that there may be windows of vulnerability to the development of shutdown dissociation. Results support the hypothesis that experienced events are more important than witnessed events, but challenge the hypothesis that “life-threatening” events are a critical determinant.
