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.     

The association of posttraumatic stress disorder,complex posttraumatic stress disorder,and borderline personality disorder from a network analytical perspective

BackgroundPosttraumatic Stress Disorder (PTSD), Complex PTSD, and Borderline Personality Disorder (BPD) share etiological risk factors and an overlapping set of associated symptoms. Since the ICD-11 proposal for trauma-related disorders, the relationship of these disorders has to be clarified. A novel approach to psychopathology, network analysis, allows for a detailed analysis of comorbidity on symptom level.MethodsSymptoms were assessed in adult survivors of childhood abuse (N = 219) using the newly developed ICD-11 Trauma-Questionnaire and the SCID-II. The psychopathological network was analyzed using the network approach.ResultsPTSD and Complex PTSD symptoms were strongly connected within disorders and to a lesser degree between disorders. Symptoms of BPD were weakly connected to others. Re-experiencing and dissociation were the most central symptoms.ConclusionsMental disorders are no discrete entities, clear boundaries are unlikely to be found. The psychopathological network revealed central symptoms that might be important targets for specific first interventions.     

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.

Neurochemical alterations in women with borderline personality disorder and comorbid attention-deficit hyperactivity disorder

Background. Borderline personality disorder (BPD) is associated with structural and functional brain changes. Recent models and findings refer to alterations of glutamate and total N-acetylaspartate (tNAA) in this condition. Methods. Absolute quantities of tNAA, creatine, glutamate, glutamine, myoinositol and total choline were measured using 3 Tesla magnetic resonance spectroscopy of the left anterior cingulate cortex and the left cerebellum in 14 unmedicated women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD) and 18 healthy women. Both groups were matched with respect to age, education and premorbid intelligence. Results. In the anterior cingulate, we found significantly higher tNAA and glutamate concentrations and a trend for lower glutamine levels in women with BPD and comorbid ADHD as compared to healthy women. There were no significant group differences in cerebellar metabolite concentrations. Conclusions. Glutamatergic changes in the anterior cingulate may be associated with BPD and comorbid ADHD. Increased anterior cingulate tNAA may indicate disturbed energy metabolism or impaired frontal maturation.

Electroconvulsive therapy for depression with comorbid borderline personality disorder or post-traumatic stress disorder: A matched retrospective cohort study

Background

The impact of comorbid borderline personality disorder (BPD) or post-traumatic stress disorder (PTSD) on clinical and cognitive outcomes of electroconvulsive therapy (ECT) in patients with major depressive episodes (MDE) is unknown.

Hippocampal volume deficits associated with exposure to psychological trauma and posttraumatic stress disorder in adults: A meta-analysis

Trauma exposure itself in the absence of posttraumatic stress disorder (PTSD) may be associated with hippocampal volume deficits. We meta-analytically compared hippocampal volumes in PTSD subjects, in trauma-exposed subjects without PTSD, and in trauma-unexposed subjects. Using the words and phrases PTSD, neuroimaging, hippocampus, brain, violence, trauma, abuse, rape, war, combat, accident, and disaster, we searched major computerized databases to obtain candidate studies through 2008 for inclusion. We identified 39 hippocampal volumetric studies in adults with PTSD compared to control groups consisting of either trauma-exposed controls without PTSD or trauma-unexposed controls, or both. We meta-analytically compared left, right, and total hippocampal volumes between 1) PTSD subjects and a trauma-unexposed group, 2) PTSD subjects and a trauma-exposed group without PTSD, and 3) a trauma-unexposed group and a trauma-exposed group without PTSD. Hippocampal volumes were smaller in the PTSD group and trauma-exposed group without PTSD compared to the trauma-unexposed group. Further, the right hippocampus was smaller in the PTSD group compared to the trauma-exposed group without PTSD. Additionally, the right hippocampus was larger than the left in the PTSD and trauma-unexposed groups but not in the trauma-exposed group without PTSD. Hippocampal volume reduction is associated with trauma exposure independent of PTSD diagnosis, albeit additional hippocampal reduction was found in PTSD compared to the trauma-exposed group without PTSD.     

Hippocampal function during associative learning in patients with posttraumatic stress disorder

In the last decade several studies have shown memory deficits in patients with posttraumatic stress disorder (PTSD) which have been associated with a reduced hippocampus volume. However, until now we do not know how or whether these structural abnormalities turn into functional abnormalities. Thus, the primary purpose of the present study was the investigation of the hippocampal function using functional magnet resonance imaging (fMRI).We compared PTSD patients and healthy control participants using an associative learning paradigm consisting of two encoding and one retrieval condition. During fMRI scanning participants had to learn face-profession pairs. Afterwards only faces were presented as cue stimuli for associating the category of the prior learned target profession and the participants had to decide whether this face belonged to a scientific or an artistic profession. Additionally, cognitive functioning, i.e. memory and attention, was examined using neuropsychological standard tests.During encoding PTSD patients showed stronger hippocampal and weaker prefrontal activation compared to healthy control participants. During retrieval the two groups did not differ neither in hippocampus activation nor in accuracy of retrieval. PTSD patients however showed a reduced activation in the left parahippocampal gyrus and other memory-related brain regions. We did not find any significant memory differences between PTSD patients and healthy control participants.The results suggest that PTSD has an effect on memory-related brain function despite intact memory functioning. In particular the hippocampal/parahippocampal regions and the prefrontal cortex show functional alterations during associative learning and memory.     

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.     

Reduced hippocampal volume and total white matter volume in posttraumatic stress disorder.

BACKGROUND: Reduced hippocampal volumes in posttraumatic stress disorder (PTSD) patients are thought to reflect specific changes of this structure. Previous magnetic resonance imaging (MRI) studies have not consistently examined indices of overall brain atrophy, therefore it cannot be completely ruled out that hippocampal changes are explained by whole-brain atrophy. The purpose of this study was to assess hippocampal and whole-brain volume in civilian PTSD. METHODS: Twelve subjects with PTSD and 10 control subjects underwent brain MRI. Hippocampal volumes were visually quantified using a computerized volumetric program. Whole-brain volumes were obtained with automated k-means-based segmentation. RESULTS: No differences were found in intracranial volumes (ICV). Subjects with PTSD had higher cerebrospinal fluid (CSF)/ICV ratios and lower white matter/ICV ratios, consistent with generalized white matter (WM) atrophy. The effect of age on CSF/ICV was more pronounced in the PTSD group. Subjects with PTSD had smaller absolute and normalized bilateral hippocampal volumes. These differences persisted after adjusting for lifetime weeks of alcohol intoxication. Posttraumatic stress disorder and depression scores correlated negatively with left hippocampal volume, but PTSD scores were a better predictor of hippocampal volumes. CONCLUSIONS: Our results replicate previous findings of reduced hippocampal volume in PTSD but also suggest independent, generalized, white matter atrophy.     

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.

Obsessive-compulsive disorder comorbid with borderline personality disorder: A long-term case study

Abstract Three case reports of patients with borderline personality disorder (BPD) and obsessive-compulsive disorder (OCD) for more than 10 years are used to illustrate the relationship between OCD and borderline pathology. The recognizable features of the obsessive-compulsive symptoms in these reports are: (i) pervasiveness, the symptomatic overlap of obsessive-compulsive symptoms; (ii) poor insight and resistance; and (iii) obsessive control evident in personal relationships. These features are manifestations of OCD psychopathology as well as of a personality disorder. The symptoms with these features are located hypothetically towards the severe end of the symptomatic spectrum of OCD. The comorbidity is not a simple relationship, and the symptomatology of the comorbid patient is derived from OCD pathology linked with the personality disorder rather than from independent BPD pathology.     

Neuroimaging in borderline personality disorder

Neuroimaging has become one of the most important methods in the investigation of the neurobiological underpinnings of borderline personality disorder. Structural and functional imaging studies have revealed dysfunction in different brain regions which seem to contribute to borderline symptomatology. This review presents relevant studies using different methodologies: volumetry of limbic and prefrontal regions, investigations of brain metabolism under resting conditions, studies of serotonergic neurotransmission, and challenge studies using emotional, stressful, and sensory stimuli. Dysfunction in a frontolimbic network is suggested to mediate much, if not all of the borderline symptomatology.     

Reduced anterior and posterior cingulate gray matter in borderline personality disorder.

BACKGROUND: Structural abnormalities in prefrontal and cingulate gyrus regions-important in affective processing, impulse control and cognition may contribute to the psychopathology of borderline personality disorder (BPD). Previous MRI studies examining volume have reported that compared with healthy controls, BPD patients have decreases in right anterior cingulate, no differences in dorsolateral prefrontal cortex, and mixed findings for prefrontal cortex. We extended this investigation by examining gray and white matter volume of frontal and cingulate gyrus Brodmann areas (BAs) in a large group of patients and healthy controls. METHODS: MRI scans were acquired in 50 BPD patients (n = 13 with comorbid diagnosis of BPD and Schizotypal Personality Disorder (SPD) and n = 37 without SPD) and 50 healthy controls, and gray/white matter volume in cingulate gyrus and frontal lobe BAs were assessed. Normal BPD and BPD subgroup comparisons were conducted. RESULTS: Compared with controls, BPD patients showed reduced gray matter volume in BA 24 and 31 of the cingulate. BPD patients without comorbid SPD had isolated gray matter volume loss in BA 24, but were spared for BA 31 in contrast to BPD patients with SPD. There were no group differences in whole cingulate or frontal lobe volume. CONCLUSIONS: The finding of more pervasive cingulate shrinkage in the patients with BPD and SPD comorbidity resembles recent observations with the same methods in patients with schizophrenia. The pattern of reduced anterior and posterior cingulate gray matter volume in BPD patients, particularly those comorbid for SPD is consistent with the affective and attentional deficits observed in these personality disorders.     

Reduced cortical and subcortical volumes in female adolescents with borderline personality disorder

Volumetric alterations in limbic structures have been detected in adults, but not in adolescents with borderline personality disorder (BPD). We examined adolescents in the early stages of BPD to provide a unique opportunity to investigate which parts of the brain are initially affected by the disorder before confounding factors such as long-term medication or chronicity can mask them. A group of 60 right-handed female adolescents between 14 and 18 years of age (20 patients with BPD, 20 clinical controls, and 20 healthy controls) underwent magnetic resonance imaging (MRI). Focus was on the examination of hippocampal and amygdalar volume differences. Furthermore, a cortical thickness analysis was conducted. FreeSurfer software detected significant group differences in the right and left hippocampus and in the right amygdala. Additionally, significant volume reductions in frontal (right middle frontal gyrus, orbital part of the inferior frontal gyrus bilaterally), and parietal regions (superior parietal gyrus bilaterally) were found in adolescents with BPD compared with controls. No group differences in cortical thickness were revealed.     

Differences in attention and impulsivity between borderline personality disorder and bipolar disorder

This study aims at investigating attention and impulsivity differences between borderline personality disorder and bipolar disorder, as both diseases may share neuropsychological deficits. Differential cognitive outcomes on the Continuous Performance Test-II were observed between disorders, and also when compared to healthy controls.     

Hippocampal and amygdala volumes in children and adults with childhood maltreatment-related posttraumatic stress disorder: a meta-analysis

Little work has directly examined the course of hippocampal volume in children and adults with childhood maltreatment-related posttraumatic stress disorder (PTSD). Data from adults suggest that hippocampal volume deficits are associated with PTSD, whereas findings from children with PTSD generally show no hippocampal volume deficits in PTSD. Additionally, the role of the amygdala in emotional response makes it a possible region for investigation in children and adults with childhood maltreatment-related PTSD. The objectives of this study were 2-fold: (1) to meta-analytically determine whether hippocampal and amygdala volumes in children and adults with PTSD from childhood maltreatment differ from those in healthy controls, and (2) to use cross-sectional findings performed with meta-analyses as a proxy for longitudinal studies to estimate the course of hippocampal and amygdala volumes in child and adult subjects with PTSD from childhood maltreatment. Using electronic databases, we identified articles containing hippocampal and amygdala data for children with PTSD and adults with PTSD from childhood maltreatment. Data were extracted and effect sizes were calculated using Comprehensive Meta-Analysis Version 2.0. Reduced bilateral hippocampal volume was found in adults with childhood maltreatment-related PTSD compared with healthy controls, but this deficit was not seen in children with maltreatment-related PTSD, suggesting hippocampal volume deficits from childhood maltreatment may not be apparent until adulthood. Greater left than right hippocampal volume was found in the adult healthy control group but not in the PTSD group. Amygdala volume in children with maltreatment-related PTSD did not differ from that in healthy controls. Hippocampal volume is normal in children with maltreatment-related PTSD but not in adults with PTSD from childhood maltreatment, suggesting an initially volumetrically normal hippocampus with subsequent abnormal volumetric development occurring after trauma exposure. However, longitudinal studies are needed to support these preliminary findings.     

Voxel-based morphometric gray matter correlates of posttraumatic stress disorder

Posttraumatic stress disorder (PTSD) is associated with functional abnormalities within a neurocircuitry that includes the hippocampus, amygdala, and medial prefrontal cortex. Evidence of structural abnormalities within these regions, and their association with PTSD severity and symptom burden is, however, sparse. The present study evaluated the relation between indices of gray matter volume and PTSD symptom severity using voxel-based morphometry. Fifteen individuals meeting DSM-IV criteria for PTSD completed the Clinician Administered PTSD Scale and underwent structural magnetic resonance imaging. Greater PTSD severity and avoidance/numbing were correlated with increased gray matter volume of the right amygdala–hippocampal complex. Greater hyper-arousal was associated with reduced gray matter volume in the left superior medial frontal gyrus. Findings are consistent with current neurocircuitry models of PTSD, which posit that the disorder is associated with structural and functional variance within this distributed network.
