Borderline Personality Disorder Patients Research Articles

The comparison of hot and cold executive functions in patients with bipolar II disorder, borderline personality disorder, and healthy individuals.

Differential diagnosis of bipolar II disorder (BD-II) and borderline personality disorder (BPD) has always been challenging for clinicians due to symptoms' overlap. This study aimed to compare hot and cold executive functions (EFs) in BD-II patients, as well as BPD and healthy controls (HCs), in order to differentiate these two disorders. In the present study, 30 BD-II and 30 BPD patients undergoing the drug therapy with mood stabilizers, and 30 HC were examined using EFs evaluated tests. The data were then analyzed using ANOVA and Tukey post hoc test. The BD-II Patients performed significantly less in all cold EFs than the HC. Also, BPD patients had meaningfully lesser performance compared to HC in all cold EFs except sustained attention. No significant difference was perceived between the two patient groups in the cold EFs. In BD-II patients, the risky decision-making as a hot EFs' component was not significantly different from HC; nevertheless, its amount was significantly higher in BPD than in the HC and BD-II patients. These findings underline the differences between the two mentioned disorders based on the hot EFs, which may indicate further disorder in the emotional information processing system among the BPD patients.

A Cluster Analysis of Neuropsychological Impairment in Borderline Personality Disorder: Identifying a Neurocognitive Subtype Linked to Attention Deficit Hyperactivity Disorder.

Cognitive impairment associated with borderline personality disorder (BPD) has been consistently demonstrated. However, a specific neuropsychological profile has not yet been established for this disorder, maybe due to the heterogeneity of BPD. The aim of this work is the search for distinct neuropsychological subtypes among patients with BPD and for the association of neuropsychological subgroups with specific clinical characteristics. One hundred fifteen patients with BPD diagnosis received an extensive neuropsychological evaluation assessing attentional, memory and executive functions indexes. For subtyping strategies, a cluster analysis of neuropsychological BPD distribution was performed. Central clinical dimensions of BPD were measured and analysed in relation with the obtained neuropsychological clusters. Two clusters were found: Cluster 1 showed a significantly lower score on the working memory index, and Cluster 2 had significantly worse overall executive performance, response inhibition and planning abilities. Patients in the neurocognitive Cluster 2 showed significantly higher clinical deficits of attention as measured with subscales of the CAARS attention deficit hyperactivity disorder (ADHD) index (F = 2.549, p < 0.005, d = 11.49). Two neuropsychological clusters of patients were found in the BPD sample: Cluster 1 patients showed greater impairment in working memory, while Cluster 2 patients had greater deficits of executive functioning, particularly for response inhibition and planning. In addition, BPD patients with greater executive deficits presented greater levels of ADHD clinical features. These findings might also facilitate earlier diagnosis of severe BPD patient profiles and to establish more personalized treatment based on neurocognitive stimulation.

A Narrative Systematic Review of the Effectiveness of Repetitive Transcranial Magnetic Stimulation (rTMS) in the Treatment and Management of Borderline Personality Disorder

Background: Borderline Personality Disorder (BPD) is a psychiatric condition that affects approximately 2% of the population worldwide. It can present many challenges and can therefore be difficult to treat successfully by mental health professionals. Aim: The aim of this systematic review was to detect whether repetitive Transcranial Magnetic Stimulation (rTMS) is an effective intervention for the management of BPD to the point where there would be a reduction of the BPD symptoms and challenging behaviour. Methods: A literature search was conducted systematically using the following databases: PROSPERO, PUBMED, GOOGLE SCHOLAR, WEB OF SCIENCE, COCHRANE LIBRARY, SCOPUS, EMBASE and CLINICALTRIALS.GOV. Included studies were primary research studies of adult patients with a diagnosis of BPD who received rTMS treatment. Results: Nine studies were identified which ranged from a case report to a randomised controlled trial (RCT). While rTMS improved certain symptoms of BPD patients, such as affective instability, impulsivity and outbursts of anger; overall, some results lacked statistical significance and, due to the lack of robust evidence, it is uncertain if rTMS is an effective intervention for BPD. Conclusions: rTMS treatment showed some promising results in reducing the severity of symptoms for a number of patients. Studies varied with regard to the location of the target stimulation site, including different prefrontal brain regions and the cerebellum, as well as other rTMS protocol characteristics. These methodological differences in the application of the intervention and their impact on BPD symptomatology need to be explored more systematically in future research. Higher quality studies with larger sample sizes are needed in order to assess further the effectiveness of rTMS interventions on BPD symptoms.

Effect of Dialectical Behavior Therapy on Negative Affect, and Symptoms of Depression and Anxiety in Individuals with Borderline Personality Disorder during COVID-19 Pandemic.

Background: This study investigated the effectiveness of dialectical behavior therapy (DBT) in patients with borderline personality disorder (BPD) during the COVID-19 pandemic, assessing negative affect, depression, and anxiety levels as indicators of health. Methods: A total of 287 participants were recruited, including BPD patients at different stages of treatment and the general population without a diagnosis of BPD. Questionnaires were used to assess the fear of COVID-19 and the referenced health indicators. Results: No differences were observed between groups in levels of fear of COVID-19, but there were differences in the health indicators studied. BPD patients in long-term treatment showed levels of negative affect similar to those of the general population, while those in early treatment stages exhibited significantly higher levels. However, no significant improvements were observed in levels of depression and anxiety in the long-term treatment group compared to those who underwent the initial treatment phase. Conclusions: These findings underscore the importance of effectively intervening in BPD, especially in stress-inducing situations such as the pandemic, and suggest the need to explore complementary approaches to addressing depression and anxiety in this clinical context.

Mentalisation-based treatment for borderline personality disorder: a narrative review of recent process and outcome findings

This article presents a narrative review of recent process and outcome studies of mentalisation-based treatment (MBT) for borderline personality disorder (BPD). The author introduces the theoretical origins of mentalisation, its role in BPD, and the therapeutic approach of MBT. Quantitative and qualitative findings are then reviewed and critically appraised for their methodological strengths and limitations. The review finds that BPD patients benefit from the multicomponent structure and active ingredients of MBT. Finally, practical implications are discussed and directions for future research are proposed.

Human olfactory neural progenitor cells reveal differences in IL-6, IL-8, thrombospondin-1, and MCP-1 in major depression disorder and borderline personality disorder.

Discovering biological markers is essential for understanding and treating mental disorders. Despite the limitations of current non-invasive methods, neural progenitor cells from the olfactory epithelium (hNPCs-OE) have been emphasized as potential biomarker sources. This study measured soluble factors in these cells in Major Depressive Disorder (MDD), Borderline Personality Disorder (BPD), and healthy controls (HC). We assessed thirty-five participants divided into MDD (n=14), BPD (n=14), and HC (n=7). MDD was assessed using the Hamilton Depression Rating Scale. BPD was evaluated using the DSM-5 criteria and the Structured Clinical Interview for Personality Disorders. We isolated hNPCs-OE, collected intracellular proteins and conditioned medium, and quantified markers and soluble factors, including Interleukin-6, interleukin-8, and others. Analysis was conducted using one-way ANOVA or Kruskal-Wallis test and linear regression. We found that hNPCs-OE of MDD and BPD decreased Sox2 and laminin receptor-67 kDa levels. MASH-1 decreased in BPD, while tubulin beta-III decreased in MDD compared to controls and BPD. Also, we found significant differences in IL-6, IL-8, MCP-1, and thrombospondin-1 levels between controls and MDD, or BPD, but not between MDD and BPD. Altered protein markers are evident in the nhNPCs-OE in MDD and BPD patients. These cells also secrete higher concentrations of inflammatory cytokines than HC cells. The results suggest the potential utility of hNPCs-OE as an in vitro model for researching biological protein markers in psychiatric disorders. However, more extensive validation studies are needed to confirm their effectiveness and specificity in neuropsychiatric disorders.

Study on the Correlation between Hcy and Hs-CRP Levels and Cognitive Function in Patients with Bipolar Disorder and Borderline Personality Disorder.

This study aims to explore the correlation and clinical significance of homocysteine and high-sensitivity C-reactive protein levels with cognitive function in patients with bipolar disorder (BD) and borderline personality disorder (BPD). Patients with BD admitted to our hospital from January 2022 to December 2022 were chosen retrospectively. BPD patients were categorized into comorbidity groups, while those without BPD were assigned to non-comorbidity groups, each consisting of 60 cases. Enzyme-linked immunosorbent assay (ELISA) was utilized to assess serum levels of homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) in both patient groups. Clinical symptoms were evaluated by the Hamilton Depression Rating Scale (HAMD) and the Young Mania Rating Scale (YMRS). Cognitive function was evaluated and compared using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Pearson correlation analysis was performed on the correlation between patients' serum Hcy and hs-CRP levels and HAMD, YMRS, and RBANS scores. In the comorbidity group, patients exhibited significantly elevated serum Hcy and hs-CRP levels compared to the non-comorbidity group (p < 0.05). Patients in the comorbidity group displayed higher HAMD and YMRS scores than those in the non-comorbidity group (p < 0.05). Additionally, attention, speech, visual span, immediate memory, and delayed memory in the comorbidity group were notably lower than in the non-comorbidity group (p < 0.05). The speech, visual span, and immediate memory of RBANS in bipolar depressive patients with comorbid BPD were lower than those in bipolar depressive patients without comorbid BPD (p < 0.05), the speech of RBANS in bipolar manic patients with comorbid BPD was lower than those in bipolar manic patients without comorbid BPD (p < 0.05). Pearson correlation analysis showed that the expression of Hcy and hs-CRP in the comorbid group was positively correlated with HAMD and YMRS scores, and negatively correlated with attention, speech, visual span, immediate memory, and delayed memory, and these differences were statistically significant (p < 0.05). High serum Hcy and hs-CRP expression levels may regulate inflammatory responses, aggravating cognitive impairment in patients with BD and BPD. Serum Hcy and hs-CRP expression levels are significantly related to cognitive dysfunction. They are expected to guide the prevention and treatment of BD comorbid BPD patients.

Decreased oxytocin levels related to social cognition impairment in borderline personality disorder.

Dysfunctions in the oxytocin system have been reported in patients with borderline personality disorder (BPD). Deficits could be related to interpersonal hypersensitivity, which has been previously associated with failures in social cognition (SC) in this disorder, especially in Theory of Mind (ToM) skills. The aim of this work is to study the links between the oxytocin system and SC impairments in patients with BPD. Plasma oxytocin levels (OXT) and protein expression of oxytocin receptors in blood mononuclear cells (OXTR) were examined in 33 patients with a diagnosis of BPD (age: M 28.85, DT = 8.83). Social cognition was assessed using the Movie for the Assessment of Social Cognition (MASC). Statistical associations between biochemical factors and different response errors in MASC were analyzed through generalized linear regression controlling for relevant clinical factors. Generalized linear regression showed a significant relationship between lower OXTR and overmentalization in BPD patients (OR = 0.90). This work supports the relationship between alterations in the oxytocin system and ToM impairments observed in BPD patients, enhancing the search for endophenotypes related to the phenotypic features of the disorder to improve current clinical knowledge and address more specific therapeutic targets.

Amygdala functional connectivity in borderline personality disorder

Borderline personality disorder (BPD) is characterised by structural and functional brain alterations. Yet, there is little data on functional connectivity (FC) across different levels of brain networks and parameters. In this study, we applied a multi-level approach to analyse abnormal functional connectivity. We analysed resting-state functional magnetic resonance imaging (fMRI) data sets of 69 subjects: 17 female BPD patients and 51 age-matched psychiatrically healthy female controls. fMRI was analysed using CONN toolbox including: a) seed-based FC analysis of amygdala connectivity, b) independent component analysis (ICA) based network analysis of intra- and inter-network FC of selected resting-state networks (DMN, SN, FPN), as well as c) graph-theory based measures of network-level characteristics. We show group-level seed FC differences with higher amygdala to contralateral (superior) occipital cortex connectivity in BPD, which correlated with schema-therapy derived measures of symptoms/traits across the entire cohort. While there was no significant group effect on DMN, SN, or FPN intra-network or inter-network FC, we show a significant group difference for local efficiency and cluster coefficient for a DMN-linked cerebellum cluster. Our findings demonstrate BPD-linked changes in FC across multiple levels of observation, which supports a multi-level analysis for future studies to consider different aspects of functional connectome alterations.

The use of optical coherence tomography (OCT) and OCT angiography in borderline personality disorder compared to health control subjects.

Optical coherence tomography (OCT) or OCT angiography (OCTA) has been investigated in few research studies of psychiatric disorders. No research has been done using OCT or OCTA in patients with borderline personality disorder (BPD). OCTA measured foveal avascular zone (FAZ), macular vessel density (MVD), and peripapillary vessel density (PVD). OCT measured the peripapillary retinal fiber layer (RNFL) and central retinal thickness (CRT). The study utilized the Ottawa Self-Injury Inventory, Hamilton Anxiety Rating Scale (HAMA), and Global Assessment of Functioning (GAF) to assess the symptom characteristics of individuals with BPD. Fifty-nine eyes of BPD patients and 58 eyes of normal subjects were analyzed, MVD of the superficial retinal capillary plexus declined noticeably in most subfields (p < 0.05). Significant differences were observed in the whole inner ring and outer ring index between BPD and HC groups (p < 0.05). The patients with BPD exhibited lower RNFL and CRT, the difference was significant (p < 0.05). CRT indicated a significant negative correlation with the Ottawa Self-Injury Inventory (p < 0.05). In addition, we observed that there was a negative correlation identified between the MVD of the inner ring and HAMA (p < 0.05). Meanwhile, the MVD of the outer ring was positively correlated with GAF (p < 0.05). The areas under the receiver operating characteristic curves (AUROCs) for distinguishing BPD and HC eyes in OCTA were the highest for fovea MVD (0.679), followed by outer ring MVD (0.669), inner ring MVD (0.641), FAZ (0.579). In OCT, CRT was highest for BPD (0.711), followed by RNFL (0.625). The OCT and OCTA can non-invasively detect microvascular and morphology changes of the retina in BPD patients compared to healthy control subjects.

Childhood adversity modulates structural brain changes in borderline personality but not in major depression disorder

Adverse childhood experiences (ACEs) negatively affect the function and structure of emotion brain circuits, increasing the risk of various psychiatric disorders. It is unclear if ACEs show disorder specificity with respect to their effects on brain structure. We aimed to investigate whether the structural brain effects of ACEs differ between patients with major depression (MDD) and borderline personality disorder (BPD). These disorders share many symptoms but likely have different etiologies. To achieve our goal, we obtained structural 3T-MRI images from 20 healthy controls (HC), 19 MDD patients, and 18 BPD patients, and measured cortical thickness and subcortical gray matter volumes. We utilized the Adverse Childhood Experiences (ACE) questionnaire to quantify self-reported exposure to childhood trauma. Our findings suggest that individuals with MDD exhibit a smaller cortical thickness when compared to those with BPD. However, ACEs showed a significantly affected relationship with cortical thickness in BPD but not in MDD. ACEs were found to be associated with thinning in cortical regions involved in emotional behavior in BPD, whereas HC showed an opposite association. Our results suggest a potential mechanism of ACE effects on psychopathology involving changes in brain structure. These findings highlight the importance of early detection and intervention strategies.

Short- and Long-Term Outcomes of an Adventure Therapy Programme on Borderline Personality Disorder: A Pragmatic Controlled Clinical Trial.

Adventure Therapy (AT) is a therapeutic intervention utilizing the natural environment and adventure activities as tools for psychotherapeutic interventions. It has been demonstrated to be appropriate for the intervention of patients with borderline personality disorder (BPD). This study aims to evaluate the response to AT treatment compared with the response to treatment as usual (TAU), based on cognitive behavioural therapy, in the short and long term, assessing clinical, psychosocial, and functional outcomes; quality of life; and physical health levels. This study extends the sample of and is a follow-up to a pilot study published in 2021, with a sample of 30 patients in the AT group and 10 in the control group. It does not allow us to affirm that AT provides better outcomes than TAU, as the positive effects observed immediately after therapy seem to be attenuated in the long term. Therefore, the effectiveness of long-term psychotherapy did not show differences between AT and TAU therapies in the treatment of BPD patients. However, the effects of intangibles observed during therapy by professionals and patients were not reflected in the measurements collected. Therefore, we believe it is necessary to increase the programme duration, complement treatment with a specific physical health programme, assess results with more specific instruments, and/or move towards a qualitative methodology to measure perceived changes in clinical improvement. New studies are needed to evaluate the results of the proposed changes.

Physical health, primary care utilization and long-term quality of life in borderline personality disorder: A 10-year follow-up study in a Spanish sample

ObjectiveWe aimed to study physical health and primary care utilization in the long-term course of borderline personality disorder (BPD) and their impact on quality of life (QOL) in a Spanish clinical sample. MethodsThis study is part of a longitudinal study following a clinical cohort with BPD. A total of 41 participants were re-evaluated at 10-year follow-up, when current medical conditions, primary care utilization, and quality of life were assessed. Comparative population data were extracted from the Catalan Health Survey ESCA. Results68% of BPD patients reported physical health problems, and 32% informed of multiple medical illnesses at follow-up. Higher rates of musculoskeletal disorders and frequent use of general practitioner (GP) consultations were reported by BPD patients compared to the general population. Differences in physical health and use of primary care services between remitted and non-remitted BPD patients were not significant. BPD remission was independently associated with better long-term QOL. Comorbid somatic diseases worsened the long-term QOL of non-remitted BPD patients. ConclusionChronic somatic conditions are prevalent in people with BPD and interact negatively with persistent BPD pathology, worsening their QOL in the long-term. Health care strategies in the assistance of long-lasting BPD patients are recommended.

The Role of Pharmacotherapy and Psychotherapy in Borderline Personality Disorder - a literature review

Borderline personality disorder (BPD) is a severe and heterogeneous psychiatric disorder known to begin at a young age, often in adolescence. It is associated with suicidal behaviour and self-harm. Up to 10 per cent of BPD patients die by suicide, so it is very important to find effective methods to alleviate the symptoms of this disorder [1]. A combination of psychotherapy and pharmacotherapy seems reasonable. An obstacle to widespread access to psychotherapy is the relatively high costs associated with the salaries of highly qualified psychotherapists. Another impediment is the long time required for effective psychotherapy and the frequent phenomenon of patients with unstable emotions discontinuing therapy prematurely. On the other hand, pharmacotherapy is necessary during periods of aggravation of the disorder, such as increased emotional lability, dysphoric states associated with aggression, impulsive behaviour and the presence of pseudopsychotic symptoms. This paper is a compilation of available treatments for borderline disorder. In the context of considering effective therapies for BPD, an important aspect is the need to increase the length of therapy and the availability of professional help for patients. In addition, research points to the benefits of combining psychotherapy with pharmacotherapy to more effectively alleviate the symptoms of this heterogeneous disorder. It is noteworthy that the relatively high cost of psychotherapy and the need to decrease.

Bayesian Decision-Making Under Uncertainty in Borderline Personality Disorder.

Bayesian decision theory suggests that optimal decision-making should use and weigh prior beliefs with current information, according to their relative uncertainties. However, some characteristics of borderline personality disorder (BPD) patients, such as fast, drastic changes in the overall perception of themselves and others, suggest they may be underrelying on priors. Here, we investigated if BPD patients have a general deficit in relying on or combining prior with current information. We analyzed this by having BPD patients (n = 23) and healthy controls (n = 18) perform a coin-catching sensorimotor task with varying levels of prior and current information uncertainty. Our results indicate that BPD patients learned and used prior information and combined it with current information in a qualitatively Bayesian-like way. Our results show that, at least in a lower-level, nonsocial sensorimotor task, BPD patients can appropriately use both prior and current information, illustrating that potential deficits using priors may not be widespread or domain-general.

Impact of clinical severity on treatment response in a randomized controlled trial comparing day hospital and intensive outpatient mentalization-based treatment for borderline personality disorder.

This study examined the impact of clinical severity on treatment outcome in two programs that differ markedly in treatment intensity: day hospital mentalization-based treatment (MBT-DH) and intensive outpatient mentalization-based treatment (MBT-IOP) for borderline personality disorder (BPD). A multicenter randomized controlled trial was conducted. Participants include the full intention-to-treat sample of the original trial of N= 114 randomized BPD patients (MBT-DH n= 70, MBT-IOP n= 44), who were assessed at baseline and subsequently every 6 up to 36 months after start of treatment. Outcomes were general symptom severity, borderline features, and interpersonal functioning. Clinical severity was examined in terms of severity of BPD, general symptom severity, comorbid symptom disorders, comorbid personality disorders, and cluster C personality features. None of the severity measures was related to treatment outcome or differentially predicted treatment outcome in MBT-DH and MBT-IOP, with the exception of a single moderating effect of co morbid symptom disorders on outcome in terms of BPD features, indicating less improvement in MBT-DH for patients with more symptom disorders. Overall, patients with varying levels of clinical severity benefited equally from MBT-DH and MBT-IOP, indicating that clinical severity may not be a useful criterion to differentiate in treatment intensity.

Brain Functional Correlates of Recall of Life Events in Medication-Naïve Adolescents with Borderline Personality Disorder

Introduction: Recall of autobiographical events has been found to be impaired in borderline personality disorder (BPD), but few studies have examined if this impairment has brain functional correlates. This study evaluated brain functional alterations during autobiographical recall using medication-naive adolescent patients to avoid potential confounding effects of treatment. Methods: Thirty-two adolescent female patients with BPD who were never-medicated and without psychiatric comorbidity and 33 matched healthy females underwent fMRI while they viewed individualized cue words that evoked autobiographical memories. Control conditions included viewing non-memory-evoking cues and a low-level baseline (cross-fixation). Results: During autobiographical recall, in comparison to the low-level baseline, the BPD patients showed increased brain activity in regions including the posterior hippocampus, the lingual and calcarine cortex, and the precuneus compared to the healthy controls. The BPD patients also showed a failure to deactivate the right dorsolateral prefrontal cortex during autobiographical recall. No patient-control differences were found when memory-evoking words were compared to non-memory-evoking words. Discussion/Conclusions: This study finds evidence of hippocampal/lingual/calcarine/precuneus hyperactivation to stimuli that evoke autobiographical memories in patients with BPD. As the changes were seen in never-treated patients without other comorbidities, they could be considered intrinsic to the disorder. Our study also adds to existing evidence for failure of deactivation in BPD, this time outside the default mode network.

The Brain Structure of Patients with Borderline Personality Disorder: A Review of Positron Emission Tomography and Structural Magnetic Resonance Imaging

Borderline personality disorder (BPD) is a severe mental disorder characterized by a consistent pattern of emotional inconsistency, poor impulse management, unstable personal relationships, and a constantly fluctuating self-image. Researchers have lately made significant progress in grasping the potential neurobiological underpinnings of BPD, and neuroimaging has emerged as a pivotal instrument in examining differences between BPD patients and healthy controls. This article will explore past studies on neuroimaging of patients with bipolar disorder, including PET and sMRI. BPD patients are likely to display hypometabolism in prefrontal regions and metabolic changes in temporal and parietal lobes. There are also studies pointing to the significance of anterior cingulate cortex (ACC) and structural volume. However, the results are mainly inconsistent. The limiting sample sizes may be one of the reasons for such a high level of variance. Therefore, studies with larger and more inclusive sample sizes are needed to reach firm conclusions. Moreover, the relationship between medication/therapy and the changes in BPD patients brain activities also needed to be explored.

Gender differences in borderline personality disorder: a narrative review.

Borderline personality disorder (BPD) is a severe and complex mental disorder that traditionally has been found to be more frequent in the female gender in clinical samples. More recently, epidemiological studies have provided conflicting data about the prevalence of borderline disorder in the two genders in community samples. In order to explain this heterogeneity, some authors hypothesized the presence of a bias in the diagnostic criteria thresholds (more prevalent in one gender than another), in the population sampling (community versus clinical), in the instruments of evaluation (clinician versus self-report measures), and in the diagnostic construct of BPD. Beyond the question of the different prevalence of the disorder between genders, the debate remains open as to how personality and clinical characteristics, and attitude toward treatments express themselves in the two genders. This narrative review is aimed to provide an updated overview of the differences among genders in BPD in terms of diagnosis, temperamental and clinical characteristics, comorbidities, findings of neuroimaging, and treatment attitudes. Studies that specifically investigated the gender differences in BPD patients are rather limited. Most of the investigations did not consider gender as a variable or were characterized by a significant imbalance between the two genders (more commonly in favor the female gender). The main results indicated that men were more likely to endorse the criteria "intense and inappropriate anger" and "impulsivity," whereas women endorsed the criteria "chronic feelings of emptiness," "affective instability," and "suicidality/self-harm behaviors." These findings reflect differences in temperament and symptoms of the two genders. Other relevant differences concern pattern of comorbidity, specific neurobiological mechanisms and attitude to treatments. Main limitations were that only one database was searched, time of publications was limited, non-English manuscripts were excluded, and the quality of each paper was not commented.

Dream themes and rejection sensitivity of individuals with and without borderline personality disorder: a comparative study

Objectives: This study aims to determine how the dream themes of borderline personality disorder patients differ from those of without borderline personality disorder diagnosis and the mediating role of rejection sensitivity in this differentiation process. Methods: The convenience sampling method was used in the study, and the participants were 79 female borderline patients diagnosed with semi-structured interviews with criteria of DSM-5 and 79 female individuals who had not received a psychological diagnosis before and at the study interviews. Sociodemographic Information Form, Dream Themes Scale, Borderline Personality Questionnaire, and Rejection Sensitivity Scale were used in the study. Linear Regression Analysis, Hierarchical Regression Analysis, and Independent Groups T-Test were used during the investigations. Results: Borderline personality disorder patients scored higher in all sub-dimensions of the dream themes scale and rejection sensitivity scale than the control group. Borderline personality traits predicted rejection sensitivity. Borderline personality traits and rejection sensitivity together predicted dream themes. Borderline personality predicts anxiety dreams, fear dreams, and experience dreams, and rejection sensitivity mediates these predictive relationships. Conclusions: The dreams of borderline personality disorder patients have negative content covered by the impact of experiences sub-dimension on dream themes, as they contain reflections of negative content in beliefs, thoughts and emotions related to their daily lives. Rejection sensitivity plays a mediator role in borderline patient’s dreams. The study results show that it would be beneficial not to ignore the content of dreams in patients with borderline personality disorder, considering the relationship of negative dreams with daily functioning, dissociative symptoms, self-harming behaviors, and suicide attempts. Results also indicate that it might be beneficial to target rejection sensitivity to reduce aggravating dream contents.
