Clinical outcome of ECT in patients with major depression and comorbid borderline personality disorder

OBJECTIVE: Previous research suggests that the comorbidity of major depression with a personality disorder, especially borderline personality disorder, is associated with a poorer response to ECT. The authors compared the acute outcome of ECT in depressed patients with borderline personality disorder, with personality disorders other than borderline personality disorder, and with no personality disorder. METHOD: The study subjects were 139 patients with a primary diagnosis of unipolar major depression and scores of at least 20 on the 24-item Hamilton Depression Rating Scale. Patients were treated with suprathreshold right unilateral or bilateral ECT in a standardized manner and were assessed with the Hamilton depression scale within 3 days and 4-8 days after completing ECT. RESULTS: Compared to patients with personality disorders other than borderline personality disorder (N=42) and those with no personality disorder (N=77), patients with borderline personality disorder (N=20) had less symptomatic improvement assessed up to 8 days after ECT. Patients with personality disorders other than borderline personality disorder responded as well to ECT as those with no personality disorder. Borderline personality disorder patients were more likely to be female and to have medication-resistant depression than the patients in the two comparison groups; they were also younger. However, none of these differences accounted for the borderline personality disorder patients' poorer response to ECT. CONCLUSIONS: Patients with borderline personality disorder have a poorer acute response to ECT, but explanations for this finding remain elusive.

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.     

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.     

Predicting outcome for borderline personality disorder

The purpose of this study is to identify variables predictive of the psychosocial outcomes of borderline patients 2 years following an acute psychiatric hospitalization. Of the initial 88 inpatients scoring positive for the Diagnostic Interview for Borderlines (DIB), 65 (73.8%) were reinterviewed, 14 (15.9%) refused, five (5.7%) were unable to be located, and four (4.6%) suicided. The dropouts (n = 19) were significantly more likely to be single, separated, or divorced, to be male, and to be diagnosed as having co-existing antisocial personality disorder than the followed-up probands (n = 69). In terms of global functioning, over the 2-year follow-up period, 61 (87.7%) of the 69 probands were judged to be functioning normally less than 50% of the follow-up interval. Using logistic regression, two variables, initial impulse action scores and poor premorbid functioning, predicted poor versus good outcome. This study supports the literature, which indicates that the early course of borderline personality disorder (BPD) is stormy. Impulsivity and poor premorbid functioning may be predictive of poor short-term outcome in borderline patients.     

Corpus callosum abnormalities in women with borderline personality disorder and comorbid attention-deficit hyperactivity disorder

OBJECTIVE: Decreased brain volumes in prefrontal, limbic and parietal areas have been found in women with borderline personality disorder (BPD). Recent models suggest impaired structural and functional connectivity in this condition. To investigate this, we studied the thickness of the corpus callosum, the largest connecting fibre bundle in the human brain. METHODS: We acquired magnetic resonance imaging scans from 20 healthy women and 20 women with BPD and comorbid attention-deficit hyperactivity disorder. A novel computational mesh-based method was applied to measure callosal thickness at high spatial resolution. RESULTS: Women with BPD had a thinner isthmus of the corpus callosum, compared with healthy women. In the patient group, a history of childhood sexual abuse was associated with a thinner posterior body of the corpus callosum. CONCLUSION: Interhemispheric structural connectivity involving parietal and temporal areas may be impaired in women with BPD and comorbid attention-deficit hyperactivity disorder.     

Age at onset of bipolar disorder and risk for comorbid borderline personality disorder

Objectives: The relationship between bipolar disorder and cluster B personality disorders remains phenomenologically complex and controversial. We sought to examine the relationship between early age at onset of bipolar disorder and development of comorbid borderline personality disorder. Methods: A total of 100 adults in an academic specialty clinic for bipolar disorder underwent structured diagnostic interviews and clinical assessments to determine lifetime presence of comorbid borderline personality disorder, histories of childhood trauma, and clinical illness characteristics. Results: Logistic regression indicated that increasing age at onset of bipolar disorder was associated with a lower probability of developing comorbid borderline personality disorder (odds ratio = 0.91, 95% confidence interval: 0.83–0.99) while controlling for potential confounding factors, including a history of severe child trauma/abuse. Conclusion: Early onset of bipolar disorder increases the probability of developing comorbid borderline personality disorder, independent of the effects of severe childhood trauma/abuse. In patients with borderline personality disorder, prospective studies of new‐onset bipolar disorder may underestimate the prevalence of true comorbidity unless they capture the primary risk window for first‐episode mania arising before the end of adolescence.     

Juror decision-making regarding a defendant diagnosed with borderline personality disorder

Stigma is an established consequence of the Borderline Personality Disorder (BPD) diagnosis. This diagnosis is subject to revision in the International Classification of Diseases–11th Revision (ICD–11). Using the legal issue of diminished responsibility, this study applied an experimental mock-jury methodology to explore the impact of diagnostic stigma of BPD on jury decision-making. Participants were allocated to one of two versions of a simplified fictitious homicide trial. The group whose defendant was described as having a ‘severe personality disorder, borderline pattern’ rated the defendant as more dangerous, and more in need of segregation and coercive treatment, than controls where the defendant was described as having a ‘complex mental health problem’. Between-group differences in other measures, including the decision to agree a verdict of diminished responsibility, were not found. The ICD-11 ‘severe personality disorder, borderline pattern’ diagnosis may adversely impact the attitudes of jurors considering the question of diminished responsibility.     

Striatal activity in borderline personality disorder with comorbid intermittent explosive disorder: sex differences

Borderline Personality Disorder (BPD) is associated with behavioral and emotional dysregulation, particularly in social contexts; however, the underlying pathophysiology at the level of brain function is not well understood. Previous studies found abnormalities in frontal cortical and limbic areas suggestive of poor frontal regulation of downstream brain regions. However, the striatum, which is closely connected with the medial frontal cortices and plays an important role in motivated behaviors and processing of rewarding stimuli, has been understudied in BPD. Here we hypothesized that, in addition to frontal dysfunction, BPD patients may show abnormal striatal function. In this study, 38 BPD patients with intermittent explosive disorder (BPD-IED) and 36 healthy controls (HC) participated in the Point Subtraction Aggression Paradigm (PSAP), a computer game played with a fictitious other player. (18)Fluoro-deoxyglucose positron emission tomography (FDG-PET) measured relative glucose metabolism (rGMR) within caudate and putamen in response to aggression-provoking and non-provoking versions of the PSAP. Male BPD-IED patients had significantly lower striatal rGMR than all other groups during both conditions, although male and female BPD-IED patients did not differ in clinical or behavioral measures. These sex differences suggest differential involvement of frontal-striatal circuits in BPD-IED, and are discussed in relation to striatal involvement in affective learning and social decision-making.     

The correlates of comorbid antisocial personality disorder in schizophrenia

More than 15 years ago, findings from the Epidemiological Catchment Area Study indicated that antisocial personality disorder (APD) is more prevalent among persons with schizophrenia than in the general population. The present study analyzed data from a multisite investigation to examine the correlates of APD among 232 men with schizophrenic disorders, three-quarters of whom had committed at least one crime. Comparisons of the men with and without APD revealed no differences in the course or symptomatology of schizophrenia. By contrast, multivariate models confirmed strong associations of comorbid APD with substance abuse, attention/concentration problems, and poor academic performance in childhood; and in adulthood with alcohol abuse or dependence and deficient affective experience (a personality style indexed by lack of remorse or guilt, shallow affect, lack of empathy, and failure to accept responsibility for one's own actions). At first admission, men with schizophrenia and APD presented a long history of antisocial behavior that included nonviolent offending and substance misuse, and an emotional dysfunction that is thought to increase the risk of violence toward others. Specific treatments and management strategies are indicated.     

Auditory P300 in borderline personality disorder and schizophrenia

Using three sets of clinical criteria to define borderline personality disorder (BPD), P300 (P3) and other long-latency auditory event-related electroencephalographic potentials were measured in 22 subjects with BPD, 32 subjects with other personality disorders, 29 schizophrenics, 22 depressives, and 74 volunteer controls. The patients with BPD were found to differ from patients with nonborderline personality disorders, having a longer P3 latency and smaller P3 amplitude. Long-latency event-related potentials were similar in the BPD and schizophrenic groups and did not differentiate patients with BPD with a concurrent diagnosis of schizotypal personality disorder from those without schizotypal personality disorder. The P3 latency and amplitude changes distinguished the BPD and schizophrenic groups from normal controls, those with major depressive disorder, and those with nonborderline personality disorders. These findings suggest that though some patients with BPD may have depressive symptomatology, they share with schizophrenics a dysfunction of auditory neurointegration.     

Olanzapine safety and efficacy in patients with borderline personality disorder and comorbid dysthymia.

BACKGROUND: Numerous medications have been tested in patients with borderline personality disorder (BPD) and/or schizotypal personality disorder (SPD). Although many of the medications tested have been demonstrated to be useful, no clear main treatment for BPD has emerged. Despite the efficacy of some of the medicines, acceptability and side effects have proven to be barriers to the use of medication. Therefore, an open-label olanzapine trial utilizing objective ratings was performed. METHODS: Patients suffering from BPD and dysthymia were included in an 8-week, open-label study of olanzapine monotherapy. The first 4 weeks of the trial allowed for flexible dosing; during the last 4 weeks, olanzapine dose was held constant. Patients were rated on Hopkins Symptoms Checklist 90 (SCL-90), Brief Psychiatric Rating Scale (BPRS), Global Assessment of Function (GAF), Barratt Impulsivity Scale (BIS 11), and Buss-Durkee Hostility Inventory (BDHI). RESULTS: Eleven patients completed at least 2 weeks; nine of the patients finished the entire trial. There was a robust and statistically significant reduction in the five global ratings. Within the global ratings, symptoms of psychoticism, depression, interpersonal sensitivity, and anger were among the symptoms to be reduced. No movement disorder symptoms were noted for any of the patients. CONCLUSIONS: In this open-label pilot study, patients treated with olanzapine showed statistically significant reduction in self-rated and clinician-rated scales. Symptoms associated with BPD and dysthymia were among those to be substantially reduced. Further studies to explore olanzapine's efficacy versus placebo, as well as comparison to other potential treatments for BPD, are important next steps.     

Hippocampal volume in borderline personality disorder with and without comorbid posttraumatic stress disorder: A meta-analysis

Background

Several studies have found a reduction in hippocampal volume in borderline personality disorder (BPD) patients.

Methods

In order to investigate the degree to which comorbid posttraumatic stress disorder (PTSD) could account for reduction in hippocampal volume in these patients, we conducted a systematic review and meta-analysis of studies that compared hippocampal volume in BPD patients with and without PTSD relative to healthy controls.

Results

Seven articles, involving 124 patients and 147 controls, were included. We found a statistically significant reduction for the left and right hippocampus. Data from the four studies that discriminated BPD patients with and without PTSD indicate that hippocampal volumes were reduced bilaterally in BPD patients with PTSD, relative to healthy controls, but that results were mixed for BPD patients without PTSD, relative to healthy controls.

Conclusions

Results from this meta-analysis suggest that hippocampal volumes are reduced in patients with BPD, relative to healthy controls, but particularly in cases in which patients are diagnosed with comorbid PTSD.     

Posttraumatic stress disorder among children clinically diagnosed as borderline personality disorder

Using the Diagnostic Interview for Children and Adolescents, Revised Version (DICA-C-R), the authors evaluated 19 children ages 7 to 14 who had recently been clinically diagnosed as borderline personality disorder by DSM-III-R criteria. The results reveal that 78.9% of these children reported significant traumatic experiences, with 36.8% fitting DICA-C-R criteria for posttraumatic stress disorder. These findings raise the possibility that a diagnosis of borderline personality in childhood can often represent posttraumatic stress disorder.     

Prediction of the 10-year course of borderline personality disorder

OBJECTIVE: The purpose of this study was to determine the most clinically relevant baseline predictors of time to remission for patients with borderline personality disorder. METHOD: A total of 290 inpatients meeting criteria for both the Revised Diagnostic Interview for Borderlines and DSM-III-R for borderline personality disorder were assessed during their index admission with a series of semistructured interviews and self-report measures. Diagnostic status was reassessed at five contiguous 2-year time periods. Discrete survival analytic methods, which controlled for baseline severity of borderline psychopathology and time, were used to estimate hazard ratios. RESULTS: Eighty-eight percent of the patients with borderline personality disorder studied achieved remission. In terms of time to remission, 39.3% of the 242 patients who experienced a remission of their disorder first remitted by their 2-year follow-up, an additional 22.3% first remitted by their 4-year follow-up, an additional 21.9% by their 6-year follow-up, an additional 12.8% by their 8-year follow-up, and another 3.7% by their 10-year follow-up. Sixteen variables were found to be significant bivariate predictors of earlier time to remission. Seven of these remained significant in multivariate analyses: younger age, absence of childhood sexual abuse, no family history of substance use disorder, good vocational record, absence of an anxious cluster personality disorder, low neuroticism, and high agreeableness. CONCLUSIONS: The results of this study suggest that prediction of time to remission from borderline personality disorder is multifactorial in nature, involving factors that are routinely assessed in clinical practice and factors, particularly aspects of temperament, that are not.
