Dexamethasone suppression test in borderline personality disorder: impact of PTSD symptoms

The purpose of the present study was to investigate the impact of post-traumatic stress disorder (PTSD) symptoms on hypothalamic-pituitary-adrenal axis feedback regulation in 18 female patients with borderline personality disorder (BPD) and 21 healthy controls. Reduced feedback sensitivity was found in BPD patients with a low number of PTSD symptoms, while findings in the BPD group with a high number of PTSD symptoms did not differ from those in controls. The results suggest a hypo-suppression in the dexamethasone suppression test in BPD with few PTSD symptoms.     

Axis II comorbidity of borderline personality disorder: description of 6-year course and prediction to time-to-remission

OBJECTIVE: The purpose of this study was to compare the axis II comorbidity of 202 patients whose borderline personality disorder (BPD) remitted over 6 years of prospective follow-up to that of 88 whose BPD never remitted. METHOD: The axis II comorbidity of 290 patients meeting both DIB-R and DSM-III-R criteria for BPD was assessed at baseline using a semistructured interview of demonstrated reliability. Over 96% of surviving patients were reinterviewed about their co-occurring axis II disorders blind to all previously collected information at three distinct follow-up waves: 2-, 4-, and 6-year follow-up. RESULTS: Both remitted and non-remitted borderline patients experienced declining rates of most types of axis II disorders over time. However, the rates of avoidant, dependent, and self-defeating personality disorders remained high among non-remitted borderline patients. Additionally, the absence of these three disorders was found to be significantly correlated with a borderline patient's likelihood-of-remission and time-to-remission; self-defeating personality disorder by a factor of 4, dependent personality disorder by a factor of 3 1/2, and avoidant personality disorder by a factor of almost 2. CONCLUSION: The results of this study suggest that axis II disorders co-occur less commonly with BPD over time, particularly for remitted borderline patients. They also suggest that anxious cluster disorders are the axis II disorders which most impede symptomatic remission from BPD.     

The course of dissociation for patients with borderline personality disorder and axis II comparison subjects: a 10-year follow-up study

Objective: The purpose of this study was to assess the severity of dissociation reported by borderline patients and axis II comparison subjects over 10 years of prospective follow‐up. Method: The Dissociative Experiences Scale (DES) – a 28‐item self‐report measure – was administered to 290 borderline in‐patients and 72 axis II comparison subjects during their index admission. It was also re‐administered at five contiguous 2‐year follow‐up periods. Results: The overall severity of dissociative experiences of those in both study groups decreased significantly over time but was discernibly greater in borderline patients (61% vs. 43%). The same pattern emerged for the subtypes of dissociation that were studied: absorption, depersonalization and amnesia. Conclusion: The severity of dissociation declines significantly over time for even severely ill borderline patients. However, it remains as a recurring problem for over a third of those with DES scores that initially were in the range associated with trauma‐spectrum disorders.     

Dexamethasone suppression test in borderline personality disorder--effects of posttraumatic stress disorder

BACKGROUND: Divergent findings of hypothalamic-pituitary-adrenal (HPA) axis functioning in borderline personality disorder (BPD) may be caused by a different degree of comorbid posttraumatic stress disorder (PTSD), in which alterations of the HPA axis are well known. Here we investigate alterations of the HPA axis in BPD patients with and without comorbid PTSD compared to healthy controls. Considering previous findings current major depression (MDD) was taken into account as a confounding variable. METHODS: Apart from clinical assessment the 0.5 mg dexamethasone suppression test (DST) was performed in 21 female borderline patients and 23 healthy controls. RESULTS: Twelve BPD patients suffered from comorbid PTSD. Relative suppression (%) did not differ between healthy controls and the total BPD group, but BPD patients with comorbid PTSD showed increased suppression compared to those without. Comorbid MDD was not associated with suppression. CONCLUSIONS: Our results do not indicate a dysfunction of the HPA axis in BPD. However, comorbid PTSD seems to be associated with a relative hypersuppression in the 0.5 mg DST.     

The 10‐year course of psychosocial functioning among patients with borderline personality disorder and axis II comparison subjects

Zanarini MC, Frankenburg FR, Bradford Reich D, Fitzmaurice G. The 10‐year course of psychosocial functioning among patients with borderline personality disorder and axis II comparison subjects. Objective: The purpose of this study was to determine the 10‐year course of the psychosocial functioning of patients with borderline personality disorder (BPD). Method: The social and vocational functioning of 290 inpatients meeting both the Revised Diagnostic Interview for Borderlines (DIB‐R) and DSM‐III‐R criteria for BPD and 72 axis II comparison subjects were carefully assessed during their index admission. Psychosocial functioning was reassessed using similar methods at five contiguous 2‐year time periods. Results: Borderline patients without good psychosocial functioning at baseline reported difficulty attaining it for the first time. Those who had such functioning at baseline reported difficulty retaining and then regaining it. In addition, over 90% of their poor psychosocial functioning was due to poor vocational but not social performance. Conclusion: Good psychosocial functioning that involves both social and vocational competence is difficult for borderline patients to achieve and maintain over time. In addition, their vocational functioning is substantially more compromised than their social functioning.     

Hyperresponsiveness of hypothalamic-pituitary-adrenal axis to combined dexamethasone/corticotropin-releasing hormone challenge in female borderline personality disorder subjects with a history of sustained childhood abuse.

BACKGROUND: High coincidence of childhood abuse, major depressive disorder (MDD), and posttraumatic stress disorder (PTSD) has been reported in patients with borderline personality disorder (BPD). Animals exposed to early trauma show increased stress-induced hypothalamic-pituitary-adrenal (HPA) axis activity due to an enhanced corticotropin-releasing hormone (CRH) drive and glucocorticoid feedback resistance. In humans, PTSD and MDD are associated with decreased and increased resistance to glucocorticoid feedback, respectively, which might reflect persistent changes in neuroendocrine sequelae following childhood abuse. METHODS: We investigated the relationship between childhood abuse and HPA axis function using a combined dexamethasone/CRH (DEX/CRH) test in 39 BPD patients with (n = 24) and without (n = 15) sustained childhood abuse and comorbid PTSD (n = 12) or MDD (n = 11) and 11 healthy control subjects. RESULTS: Chronically abused BPD patients had a significantly enhanced corticotropin (ACTH) and cortisol response to the DEX/CRH challenge compared with nonabused subjects. Comorbid PTSD significantly attenuated the ACTH response. CONCLUSIONS: Hyperresponsiveness of the HPA axis in chronically abused BPD subjects might be due to the enhanced central drive to pituitary ACTH release. Sustained childhood abuse rather than BPD, MDD, or PTSD pathology accounts for this effect. Possibly due to an enhanced efficacy of HPA suppression by dexamethasone, PTSD attenuates the ACTH response to DEX/CRH.     

Posttraumatic stress disorder and substance use disorder in adolescent bipolar disorder

Objective: Anxiety disorders such as posttraumatic stress disorder (PTSD) and substance use disorders (SUD) are increasingly recognized as comorbid disorders in children with bipolar disorder (BPD). This study explores the relationship between BPD, PTSD, and SUD in a cohort of BPD and non‐BPD adolescents. Methods: We studied 105 adolescents with BPD and 98 non‐mood‐disordered adolescent controls. Psychiatric assessments were made using the Kiddie Schedule for Affective Disorders and Schizophrenia–Epidemiologic Version (KSADS‐E), or Structured Clinical Interview for DSM‐IV (SCID) if 18 years or older. SUD was assessed by KSADS Substance Use module for subjects under 18 years, or SCID module for SUD if age 18 or older. Results: Nine (8%) BPD subjects endorsed PTSD and nine (8%) BPD subjects endorsed subthreshold PTSD compared to one (1%) control subject endorsing full PTSD and two (2%) controls endorsing subthreshold PTSD. Within BPD subjects endorsing PTSD, seven (39%) met criteria for SUD. Significantly more SUD was reported with full PTSD than with subthreshold PTSD (χ² = 5.58, p = 0.02) or no PTSD (χ² = 6.45, p = 0.01). Within SUD, the order of onset was BPD, PTSD, and SUD in three cases, while in two cases the order was PTSD, BPD, SUD. The remaining two cases experienced coincident onset of BPD and SUD, which then led to trauma, after which they developed PTSD and worsening SUD. Conclusion: An increased rate of PTSD was found in adolescents with BPD. Subjects with both PTSD and BPD developed significantly more subsequent SUD, with BPD, PTSD, then SUD being the most common order of onset. Follow‐up studies need to be conducted to elucidate the course and causal relationship of BPD, PTSD and SUD.     

Improvement in borderline personality disorder in relationship to age

Objective: It is commonly believed that some features of borderline personality disorder (BPD) improve as individuals reach their late 30s and 40s. This study examined age‐related change in borderline criteria and functional impairment, testing the hypothesis that older age would be associated with relatively more improvement than younger age. Method: A total of 216 male and female participants with BPD were followed prospectively with yearly assessments over 6 years. Results: Participants showed similar rates of improvement in borderline features regardless of age. A significant age by study year interaction showed functioning in older subjects to reverse direction and begin to decline in the latter part of the follow‐up, in contrast to younger subjects who maintained or continued improvement over the 6 years. Despite the decline, functioning for the older subjects was comparable with or slightly better at year 6 than at year 1. Conclusion: Improvement in borderline features is not specific to the late 30s and 40s. There may be a reversal of improvement in functioning in some borderline patients in this older‐age range.     

Trauma and posttraumatic stress disorder in treatment-resistant obsessive-compulsive disorder

Prior research has indicated a seemingly unique relation between obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) that appears to relate to negative treatment outcome for OCD. However, to date, the prevalence of trauma and PTSD in individuals seeking treatment for OCD is unclear. To begin to address this gap, this study assessed history of traumatic experiences and current PTSD in individuals seeking treatment for treatment-resistant OCD. Trauma predictors of PTSD severity also were examined in this sample. Participants included 104 individuals diagnosed with treatment-resistant OCD who sought treatment over the course of 1 year from OCD specialty treatment facilities. Data were collected via naturalistic retrospective chart reviews of pre-treatment clinical intake files. Findings revealed that 82% of participants reported a history of trauma. Over 39% of the overall sample met criteria for PTSD, whereas almost 50% of individuals with a trauma history met criteria for PTSD. Interpersonal traumas and greater frequency of traumas were most predictive of PTSD severity, and individuals diagnosed with OCD and additional major depressive disorder (MDD) or borderline personality disorder (BPD) appeared at particular risk for a comorbid PTSD diagnosis. PTSD may be relatively common in individuals diagnosed with treatment-resistant OCD; and interpersonal traumas, MDD, and BPD may play a relatively strong predictive role in PTSD diagnosis and severity in such OCD patients.     

Affect intensity and lability: the role of posttraumatic stress disorder symptoms in borderline personality disorder

Background: Emotion dysregulation is likely a core psychological process underlying the heterogeneity of presentations in borderline personality disorder (BPD) and is associated with BPD symptom severity. Emotion dysregulation has also been independently associated with posttraumatic stress disorder (PTSD), a disorder that has been found to co‐occur with BPD in 30.2% of cases in a nationally representative sample. However, relatively little is known about the specific relationships between emotion dysregulation and PTSD among those diagnosed with BPD. The purpose of this study was to evaluate relationships between PTSD symptom severity and negative affect intensity and affective lability among individuals with BPD. Method: Participants were 67 individuals diagnosed with BPD (79% women; M _age = 38, SD = 10), who reported one or more DSM‐IV PTSD Criterion A events. Results: Hierarchical multiple regression analyses indicated that when examined concurrently with BPD symptom severity, PTSD symptom severity, but not BPD symptom severity, was related to negative affect intensity and affective lability. Re‐experiencing symptoms uniquely predicted affective lability, and hyperarousal symptoms uniquely predicted negative affect intensity, lending additional support to emerging literature linking re‐experiencing and hyperarousal symptoms with emotion dysregulation. Conclusions: PTSD symptom severity among individuals with a BPD diagnosis is related to elevations in emotion dysregulation. It is important to evaluate whether early treatment of PTSD symptoms provided concurrently with BPD treatment leads to enhanced improvements in emotion regulation among individuals with co‐occurring PTSD and BPD.

Predictors of self-mutilation in patients with borderline personality disorder: A 10-year follow-up study

Background

Self-mutilation is a common and serious problem in patients with borderline personality disorder (BPD). The purpose of this study was to determine the most clinically relevant baseline and time-varying predictors of self-mutilation over 10 years of prospective follow-up among patients with BPD.

Method

Four semistructured interviews assessing axis I disorders, childhood adversity, adult experiences of abuse, and experiences of self-mutilation were administered at baseline to 290 patients meeting DIB-R and DSM-III-R criteria for BPD. Three of these interviews (all except for the childhood adversity interview) and two self-report measures pertaining to dysphoric affects and cognitions were administered at each of five contiguous two-year follow-up periods.

Results

Eleven variables were found to be significant bivariate predictors of self-mutilation over the five follow-up periods. Six of these predictors remained significant in multivariate analyses: female gender, severity of dysphoric cognitions (mostly overvalued ideas), severity of dissociative symptoms, major depression, history of childhood sexual abuse, and sexual assaults as an adult.

Conclusions

Taken together, the results of this study suggest that factors pertaining to traumatic experiences throughout the lifespan are significant risk factors for self-mutilation over time. These results also suggest that major depressive episodes and cognitive symptoms, particularly overvalued ideas and dissociation, significantly heighten the risk of self-injurious behaviors tracked for a decade.     

Reduced size and abnormal asymmetry of parietal cortex in women with borderline personality disorder.

BACKGROUND: Evidence is accumulating that suggests borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) are related to small hippocampal size. Psychotic symptoms are frequent in both disorders. Psychotic spectrum disorders are known to be related to abnormalities of temporoparietal cortices. METHODS: Using structural magnetic resonance imaging (3D-MRI), parietal cortex and hippocampal volumes were assessed in 30 young women with BPD who had been exposed to severe childhood sexual and physical abuse and in 25 healthy control subjects. RESULTS: Compared with control subjects, BPD subjects had significantly smaller right parietal cortex (-11%) and hippocampal (-17%) volumes. The parietal cortex of borderline subjects showed a significantly stronger leftward asymmetry when compared with control subjects. Stronger psychotic symptoms and schizoid personality traits in borderline subjects were significantly related to reduced leftward asymmetry. Stronger trauma-related clinical symptoms and neuropsychologic deficits were significantly related to smaller hippocampal size. CONCLUSIONS: Our results are consistent with previous findings of small hippocampal size in BPD and PTSD. Reduced right parietal cortex size in individuals with BPD may reflect a neurodevelopmental deficit of the right hemisphere.     

Comorbidity of borderline personality disorder and posttraumatic stress disorder in the U.S. population

While placed on different axes of the DSM classification system, borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) have important relationships with trauma, and overlap between these disorders has long been recognized. The current study is the first to examine comorbidity of PTSD and BPD in a large nationally representative sample using a reliable and valid method of assessing Axis I and II mental disorders. Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) Wave II (N = 34,653; response rate 70.2%). Multiple regression models were used to examine differences in psychopathology, traumatic events and health-related quality of life across individuals with PTSD alone (n = 1820), BPD alone (n = 1290) and those with comorbid PTSD–BPD (n = 643). The lifetime prevalence of PTSD and BPD were 6.6% and 5.9%, respectively. Of individuals with BPD, 30.2% were also diagnosed with PTSD, whereas 24.2% of individuals with PTSD were also diagnosed with BPD. Individuals with comorbid PTSD–BPD had a poorer quality of life, more comorbidity with other Axis I conditions, increased odds of a lifetime suicide attempt, and a higher prevalence of repeated childhood traumatic events than individuals with either condition alone. These results show that PTSD and BPD have a high degree of lifetime co-occurrence but are not entirely overlapping. Their concurrence is associated with poorer functioning compared to either diagnosis alone, emphasizing the clinical utility of diagnosing both conditions. Future research should explore the determinants of having either or both diagnoses with an aim toward improved identification, prevention, and intervention.     

Posttraumatic stress disorder and fMRI activation patterns of traumatic memory in patients with borderline personality disorder.

BACKGROUND: Early traumatization and additional posttraumatic stress disorder are frequent in patients with borderline personality disorder (BPD). The purpose of this study was to investigate neural correlates of traumatic memory in BPD with and without posttraumatic stress disorder (PTSD) using functional magnetic resonance imaging (fMRI). METHODS: We studied 12 traumatized female patients BPD, 6 of them with and 6 without PTSD. According to an autobiographical interview key words (cues) were defined for traumatic and for negative but nontraumatic episodes. In a block-designed fMRI task patients recalled these episodes. Contrasts between trauma condition and nontrauma condition were analyzed. RESULTS: Analyses for all subjects revealed activation of orbitofrontal cortex areas in both hemispheres, anterior temporal lobes, and occipital areas. In the subgroup without PTSD, activation of orbitofrontal cortex on both sides and Broca's area predominated. In the subgroup with additional PTSD, we observed right more than left activation of anterior temporal lobes, mesiotemporal areas, amygdala, posterior cingulate gyrus, occipital areas, and cerebellum. CONCLUSIONS: Dependent on absence or presence of additional PTSD different neural networks seem to be involved in the traumatic memory of patients with BPD.     

The 10-year course of physically self-destructive acts reported by borderline patients and axis II comparison subjects

Objective: The purpose of this paper was to determine the frequency and methods of two forms of physically self‐destructive acts (i.e. self‐mutilation and suicide attempts) reported by borderline patients and axis II comparison subjects over 10 years of prospective follow‐up. Method: Two hundred and ninety borderline patients and 72 axis II comparison subjects were interviewed about their physically self‐destructive acts during their index admission and at five contiguous 2‐year follow‐up periods. Results: It was found that a high percentage of borderline patients reported multiple acts and methods of each of these two forms of physically self‐destructive behavior prior to their index admission. It was also found that the percentage of borderline patients reporting multiple acts and methods declined significantly over time. However, these acts remained significantly more common among borderline patients than axis II comparison subjects. Conclusion: The course of self‐mutilation and suicide attempts among borderline patients is initially more serious and ultimately more benign than previously recognized.     

A three‐year follow‐up study of the psychosocial predictors of delayed and unresolved post‐traumatic stress disorder in Taiwan Chi‐Chi earthquake survivors

Aims: To predict the longitudinal course of post‐traumatic stress disorder (PTSD) in survivors three years following a catastrophic earthquake using multivariate data presented six months after the earthquake. Methods: Trained assistants and psychiatrists used the Disaster‐related Psychological Screening Test (DRPST) to interview earthquake survivors 16 years and older and to assess current and incidental psychopathology. A total of 1756 respondents were surveyed over the three‐year follow‐up period. Results: A total of 38 (9.1%) of the original 418 PTSD subjects and 40 of the original 1338 (3.0%) non‐PTSD subjects were identified as having PTSD at the 3‐year post‐earthquake follow up. Younger age, significant financial loss, and memory/attention impairment were predictive factors of unresolved PTSD and delayed PTSD. Conclusions: The longitudinal course of PTSD three years after the earthquake could be predicted as early as six months after the earthquake on the basis of demographic data, PTSD‐related factors, and putative factors for PTSD.     

Trauma, dissociation, and posttraumatic stress disorder in female borderline patients with and without substance abuse problems

OBJECTIVE: To examine the associations of childhood traumatic experiences and childhood neglect with dissociative experiences and posttraumatic stress disorder (PTSD) in a population of female borderline personality disorder (BPD) patients with and without substance abuse. METHOD: The sample included 64 female patients with BPD. Childhood traumatic experiences and childhood neglect were measured using the Structured Trauma Interview, dissociative experiences with the Dissociative Experiences Scale, and PTSD with the Structured Clinical Interview for DSM-IV. RESULTS: In general, dissociation scores were higher among those with a history of childhood trauma and neglect, in particular among those who reported both sexual and physical abuse before age 16, more than one perpetrator and severe maternal dysfunction. The prevalence of PTSD was clearly associated with the severity of childhood sexual abuse (CSA) in terms of the occurrence of penetration during CSA, intrafamilial CSA, a duration of CSA longer than 1 year and more than one perpetrator. Comorbid substance abuse problems modified the observed associations such that the associations mentioned above were also present or even more pronounced among those without substance abuse, whereas no associations were found in those with substance abuse. CONCLUSIONS: The results suggest a moderately strong association between childhood trauma and neglect with dissociation and PTSD. However, trauma-dissociation and trauma-PTSD links were only observed among BPD patients without addictive problems. The findings are largely consistent with the literature. Potential explanations for the lack of a trauma-dissociation and trauma-PTSD link in the addicted subgroup are discussed.     

Implementation and clinical characteristics of a posttraumatic stress disorder brain collection

A postmortem human brain collection to study posttraumatic stress disorder (PTSD) is critical for uncovering the molecular mechanisms that contribute to this psychiatric disorder. We describe here the PTSD brain collection at the Lieber Institute for Brain Development in Baltimore, Maryland, consisting of postmortem brain donations acquired between 2012 and 2017. Thus far, 87 brains from individuals meeting DSM‐5 criteria for PTSD were collected after consent was obtained from legal next‐of‐kin, and subsequently clinically characterized for molecular studies. PTSD brain donors had high rates of comorbid diagnoses, including depression (62.1%), substance abuse (74.7%), drug‐related death (69.0%), and suicide completion (17.2%). PTSD cases were subdivided into two categories: combat‐related PTSD (n = 24) and noncombat/domestic PTSD (n = 63). The major differences between the combat‐related and domestic PTSD cohorts were sex, drug‐related death, and the prevalence of bipolar disorder (BPD) comorbidity. The combat‐related group was entirely male, with only one BPD subject (4.2%), and had significantly fewer drug‐related deaths (45.8%) in contrast to the domestic group (31.8% male, 36.5% bipolar, and 77.8% drug‐related deaths). Medical examiners' offices, particularly in areas with higher military populations, are an excellent source for PTSD brain donations of both combat‐related and domestic PTSD.     

Predictors of response to Systems Training for Emotional Predictability and Problem Solving (STEPPS) for borderline personality disorder: an exploratory study

Objective: Few predictors of treatment outcome or early discontinuation have been identified in persons with borderline personality disorder (BPD). Aim: The aim of the study was to examine the relationship between baseline clinical variables and treatment response and early discontinuation in a randomized controlled trial of System Training for Emotional Predictability and Problem Solving, a new cognitive group treatment. Method: Improvement was rated using the Zanarini Rating Scale for BPD, the Clinical Global Impression Scale, the Global Assessment Scale and the Beck Depression Inventory. Subjects were assessed during the 20 week trial and a 1‐year follow‐up. Results: Higher baseline severity was associated with greater improvement in global functioning and BPD‐related symptoms. Higher impulsivity was predictive of early discontinuation. Optimal improvement was associated with attending ≥15 sessions. Conclusion: Subjects likely to improve have the more severe BPD symptoms at baseline, while high levels of impulsivity are associated with early discontinuation.     

Pain sensitivity is reduced in borderline personality disorder,but not in posttraumatic stress disorder and bulimia nervosa

Background. Several studies revealed reduced pain sensitivity in patients suffering from borderline personality disorder (BPD) under baseline and stress conditions. To establish whether these findings are specific for BPD, we compared pain thresholds in patients with BPD, posttraumatic stress disorder (PTSD), bulimia nervosa, and healthy controls. Methods. The study included 76 female subjects: 16 patients with BPD, 16 patients with PTSD, 20 patients with bulimia nervosa and 24 healthy controls. Heat and cold pain thresholds were assessed under baseline and stress conditions, using a contact thermode. Mental stress was induced by the Paced Auditory Serial Addition Task. Results. Under baseline conditions, pain thresholds in patients with BPD were significantly higher compared to healthy controls. Patients with PTSD and bulimia nervosa did not show significant differences in pain thresholds compared to healthy controls. Under stress conditions, the difference between BPD patients and healthy controls became even more prominent, whereas the results in the other patient groups remained insignificant. Conclusions. Our results support the hypothesis that reduced pain sensitivity is a prominent feature of BPD, which may differentiate this disorder from other stress-related psychiatric conditions.
