Posttraumatic stress disorder following recent-onset psychosis : an unrecognized postpsychotic syndrome

Patrick D. McGorry; Andrew M. Chanen; Elizabeth A. McCarthy; Raphael van Riel; Dean Philip McKenzie; Bruce Singh

Clinical experience with psychotic patients early in the course of their illness suggested that symptoms of posttraumatic stress disorder (PTSD) may not be uncommon after recovery from an acute psychotic episode. Thirty-six patients recovering from an acute psychotic episode within 2 to 3 years of onset of their illness were assessed as inpatients and followed up on two occasions during the year after discharge. The prevalence of PTSD was found to be 46% at 4 months and 35% at 11 months, measured by a questionnaire linked to DSM-III criteria. The relationships between negative symptomatology and PTSD symptoms and between depressive symptomatology and PTSD symptoms were also examined; a significant correlation was found only for the latter. The psychopathological, preventive, and therapeutic implications of these findings are discussed, and future research strategies are proposed.

BACKGROUND No accepted intervention exists for borderline personality disorder presenting in adolescence. AIMS To compare the effectiveness of up to 24 sessions of cognitive analytic therapy (CAT) or manualised good clinical care (GCC) in addition to a comprehensive service model of care. METHOD In a randomised controlled trial, CAT and GCC were compared in out-patients aged 15-18 years who fulfilled two to nine of the DSM-IV criteria for borderline personality disorder. We predicted that, compared with the GCC group, the CAT group would show greater reductions in psychopathology and parasuicidal behaviour and greater improvement in global functioning over 24 months. RESULTS Eighty-six patients were randomised and 78 (CAT n=41; GCC n=37) provided follow-up data. There was no significant difference between the outcomes of the treatment groups at 24 months on the pre-chosen measures but there was some evidence that patients allocated to CAT improved more rapidly. No adverse effect was shown with either treatment. CONCLUSIONS Both CAT and GCC are effective in reducing externalising psychopathology in teenagers with sub-syndromal or full-syndrome borderline [corrected] personality disorder. Larger studies are required to determine the specific value of CAT in this population.

UNLABELLED Young people with borderline personality disorder (BPD) commonly seek help but often go unrecognized. Screening offers a means of identifying individuals for more detailed assessment for early intervention and for research. AIMS This study compared the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Borderline Personality Questionnaire (BPQ), the BPD items from the International Personality Disorder Examination Screening Questionnaire and the BPD items from the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II) Personality Questionnaire. METHOD 101 outpatient youth (aged 15-25 years) completed the screening measures and were interviewed, blind to screening status, with the SCID-II BPD module. The screening measures were readministered two weeks later to assess test-retest reliability. RESULTS All four instruments performed similarly but the BPQ had the best mix of characteristics, with moderate sensitivity (0.68), the highest specificity (0.90), high negative predictive value (0.91) and moderate positive predictive value (0.65). Compared to the other three instruments, the BPQ had the highest overall diagnostic accuracy (0.85), a substantially higher kappa (0.57) with the criterion diagnosis, the highest test-retest reliability (ICC = 0.92) and the highest internal consistency (alpha = 0.92). The only clear difference to emerge in the Receiver Operator Curve (ROC) analysis was that the BPQ significantly outperformed the MSI (p = 0.05). CONCLUSION Screening for BPD in out-patient youth is feasible but is not a replacement for clinical diagnosis.

It is not known whether the fronto-limbic volume reductions found in adults with established borderline personality disorder (BPD) are present early in the disorder. The aim of the study was to investigate orbitofrontal cortex (OFC), hippocampal and amygdala volumes in a first-presentation teenage BPD sample with minimal exposure to treatment. Groups of 20 BPD patients and 20 healthy control participants underwent magnetic resonance imaging. Hippocampal, amygdala, OFC and whole brain volumes were estimated and compared between the two groups. Analysis of variance revealed reversal of the normal (right>left) asymmetry of OFC grey matter volume in the BPD group, reflecting right-sided OFC grey matter loss in the BPD group compared with control participants. No significant differences were found for amygdala or hippocampal volumes comparing BPD with control participants. We identified OFC but not hippocampal or amygdala volumetric differences early in the course of BPD. Hippocampal and amygdala volume reductions observed in adult BPD samples might develop during the course of the disorder, although longitudinal studies are needed to examine this.

Borderline Personality Disorder in Young People and the Prospects for Prevention and Early Intervention

Andrew M. Chanen; Martina Jovev; Louise McCutcheon; Henry J. Jackson; Patrick D. McGorry

Borderline personality disorder (BPD) is associated with substantial psychosocial impairment, morbidity, mortality and high health resource utilization. These data make a compelling case for developing prevention and early intervention strategies for BPD. This review examines the BPD diagnosis in young people, along with prospective risk factors for and precursors to the development of BPD. It then considers the prospects for and potential risks and benefits associated with prevention and early intervention for BPD. It concludes that the BPD diagnosis in young people has similar reliability, validity and prevalence to BPD in adults and that BPD in young people almost certainly has serious and pervasive negative repercussions over subsequent decades. Current data are inadequate to inform specific universal or selective prevention programs for BPD. However, they do support including BPD prevention as an outcome when evaluating universal and/or selective interventions for a variety of mental health problems and adverse psychosocial outcomes. The data are stronger for developing indicated preventive interventions but the strongest data support early intervention for the emerging BPD phenotype. Early intervention programs will need to be realistic in their aims, require change in clinician attitudes and service systems and must be mindful of the risk of iatrogenic harm.

Developmental Pathways to Borderline Personality Disorder

Andrew M. Chanen; Michael Kaess

This paper reviews recent studies of biological and environmental risk and protective factors and patterns of continuity leading to borderline personality disorder (BPD). It focuses on prospective studies of children and adolescents and studies of young people with borderline pathology, reporting findings from genetics, neurobiology, experimental psychopathology, environmental risk, and precursor signs and symptoms. Studies of individuals earlier in the course of BPD demonstrate relatively consistent environmental risk factors, but neurobiological and experimental psychopathology findings are still inconsistent. Also, temperamental and mental state abnormalities that resemble aspects of the BPD phenotype emerge in childhood and adolescence and presage the BPD syndrome in adolescence or adulthood. Further work is required to better understand the roles that all these factors play in the developmental pathways to BPD and to increase their specificity for BPD in order to facilitate prevention and early intervention.

Prevention and early intervention for borderline personality disorder: current status and recent evidence

Andrew M. Chanen; Louise McCutcheon

Borderline personality disorder (BPD) is a leading candidate for developing empirically based prevention and early intervention programmes because it is common in clinical practice, it is among the most functionally disabling of all mental disorders, it is often associated with help-seeking, and it has been shown to respond to intervention, even in those with established disorder. Moreover, it can be reliably diagnosed in its early stages and it demarcates a group with high levels of current and future morbidity and mortality. Data also suggest considerable flexibility and malleability of BPD traits in youth, making this a key developmental period during which to intervene. Novel indicated prevention and early intervention programmes have shown that BPD in young people responds to intervention. Further work is required to develop appropriate universal and selective preventive interventions.

INTRODUCTION We have developed ultra-high risk criteria for bipolar affective disorder (bipolar at-risk - BAR) which include general criteria such as being in the peak age range of the onset of the disorder and a combination of specific criteria including sub-threshold mania, depressive symptoms, cyclothymic features and genetic risk. In the current study, the predictive validity of these criteria were tested in help-seeking adolescents and young adults. METHOD This medical file-audit study was conducted at ORYGEN Youth Health (OYH), a public mental health program for young people aged between 15 and 24years and living in metropolitan Melbourne, Australia. BAR criteria were applied to the intake assessments of all non-psychotic patients who were being treated in OYH on 31 January, 2008. All entries were then checked for conversion criteria. Hypomania/mania related additions or alterations to existing treatments or initiation of new treatment by the treating psychiatrist served as conversion criteria to mania. RESULTS The BAR criteria were applied to 173 intake assessments. Of these, 22 patients (12.7%) met BAR criteria. The follow-up period of the sample was 265.5days on average (SD 214.7). There were significantly more cases in the BAR group (22.7%, n=5) than in the non-BAR group (0.7%, n=1) who met conversion criteria (p<.001). CONCLUSIONS These findings support the notion that people who develop a first episode of mania can be identified during the prodromal phase. The proposed criteria need further evaluation in prospective clinical trials.

Impulsivity in borderline personality disorder: Reward-based decision-making and its relationship to emotional distress

Katherine Lawrence; J. Sabura Allen; Andrew M. Chanen

Impulsivity in Borderline Personality Disorder (BPD) has been defined as rapid and unplanned action. However, a preference for immediate gratification and discounting of delayed rewards might better account for the impulsive behaviors that appear to regulate emotional distress in BPD. To investigate this, a delay discounting task was administered to 30 outpatients diagnosed with BPD and 28 healthy community controls (all aged 15-24) before and after a mood induction. Trait impulsivity was measured with the Barratt Impulsiveness Scale. The results showed that the BPD group had a greater preference for immediate gratification and higher rate of discounting the delayed reward than the control group. Although the mood induction resulted in increased feelings of rejection and anger in all participants, and the rate of delay discounting changed significantly in the control group, the rate of discounting did not change for the BPD group. There was no evidence of rapid decision-making in the BPD group as response times were similar between the two groups during both trials. Finally, greater general impulsiveness and nonplanning impulsiveness were associated with greater rates of discounting in the BPD group. Together these findings suggest that BPD is characterized by a preference for immediate gratification and tendency to discount longer-term rewards. This characteristic appears to exist independent of feelings of rejection and anger, rather than being reactive to this, and to be related to trait impulsivity.

Borderline Personality Disorder in Adolescence

Michael Kaess; Romuald Brunner; Andrew M. Chanen

Borderline personality disorder (BPD) is a common and severe mental disorder that is associated with severe functional impairment and a high suicide rate. BPD is usually associated with other psychiatric and personality disorders, high burden on families and carers, continuing resource utilization, and high treatment costs. BPD has been a controversial diagnosis in adolescents, but this is no longer justified. Recent evidence demonstrates that BPD is as reliable and valid among adolescents as it is in adults and that adolescents with BPD can benefit from early intervention. Consequently, adolescent BPD is now recognized in psychiatric classification systems and in national treatment guidelines. This review aims to inform practitioners in the field of adolescent health about the nature of BPD in adolescence and the benefits of early detection and intervention. BPD diagnosis and treatment should be considered part of routine practice in adolescent mental health to improve these individuals’ well-being and long-term prognosis.
