Associations of self-reported past "psychotic" phenomena with features of personality disorders

Psychotic symptoms in borderline personality disorder: an update

PURPOSE OF REVIEW

The purpose of this article is to review the most recent literature on psychotic symptoms in borderline personality disorder (BPD).

RECENT FINDINGS

Both auditory hallucinations and delusional ideation (especially paranoid delusions) are relatively common in individuals with BPD. It is still difficult to distinguish these and related phenomena in BPD from the corresponding experiences in psychotic disorders and schizophrenia, despite numerous attempts to do so. The terminology introduced to help with this effort has not been particularly useful. The presence of auditory hallucinations may affect the course of BPD negatively. Psychotic symptoms in BPD seem to be significantly related to the context (usually stressful events) and appear or intensify in response to situational crisis. The role of certain co-occurring disorders in increasing the risk of psychotic symptoms in BPD remains uncertain.

SUMMARY

Psychotic symptoms in BPD continue to be poorly understood. Further research should try to ascertain the relationships between hallucinations and delusions on one hand and the processing of trauma, emotion regulation, distress tolerance and interpersonal sensitivity on the other. Ultimately, such endeavor will contribute to developing more effective treatments for BPD.

Self-reported symptoms of schizotypal and borderline personality disorder in patients with mood disorders

BACKGROUND

Distinguishing between symptoms of schizotypal (SPD) and borderline personality disorders (BPD) is often difficult due to their partial overlap and frequent co-occurrence. We investigated correlations in self-reported symptoms of SPD and BPD in questionnaires at the levels of both total scores and individual items, examining overlapping dimensions.

METHODS

Two questionnaires, the McLean Screening Instrument (MSI) for BPD and the Schizotypal Personality Questionnaire Brief (SPQ-B) for SPD, were filled in by patients with mood disorders (n=282) from specialized psychiatric care in a study of the Helsinki University Psychiatric Consortium. Correlation coefficients between total scores and individual items of the MSI and SPQ-B were estimated. Multivariate regression analysis (MRA) was conducted to examine the relationships between SPQ-B and MSI.

RESULTS

The Spearman's correlation between total scores of the MSI and SPQ-B was strong (rho=0.616, P<0.005). Items of MSI reflecting disrupted relatedness and affective dysregulation correlated moderately (rφ varied between 0.2 and 0.4, P<0.005) with items of SPQ. Items of MSI reflecting behavioural dysregulation correlated only weakly with items of SPQ. In MRA, depressive symptoms, sex and MSI were significant predictors of SPQ-B score, whereas symptoms of anxiety, age and SPQ-B were significant predictors of MSI score.

CONCLUSIONS

Items reflecting cognitive-perceptual distortions and affective symptoms of BPD appear to overlap with disorganized and cognitive-perceptual symptoms of SPD. Symptoms of depression may aggravate self-reported features of SPQ-B, and symptoms of anxiety features of MSI. Symptoms of behavioural dysregulation of BPD and interpersonal deficits of SPQ appear to be non-overlapping.

Covariance and specificity in adolescent schizotypal and borderline trait expression

AIMS

The first aim of the present study is to assess the overlap between borderline and schizotypal traits during adolescence. The second objective is to examine whether some psychological factors (i.e. cognitive coping mechanisms, impulsivity and encoding style) are differentially related to borderline and schizotypal traits and may therefore improve the efficiency of clinical assessments.

METHODS

One hundred nineteen community adolescents (57 male) aged from 12 to 19 years completed a set of questionnaires evaluating the expression of borderline and schizotypal traits as well as cognitive emotion regulation (CER), impulsivity and encoding style.

RESULTS

Our data first yielded a strong correlation between borderline and schizotypal scores (r = 0.70, P < 0.001). Secondly, linear regression models indicated that the 'catastrophizing' CER strategy and the 'lack of premeditation' impulsivity facet accounted for the level of borderline traits, whereas an internal encoding style predominantly explained schizotypal traits.

CONCLUSIONS

Our results support the abundant literature showing that borderline and schizotypal traits frequently co-occur. Moreover, we provide original data indicating that borderline and schizotypal traits during adolescence are linked to different specific psychological mechanisms. Thus, we underline the importance of considering these mechanisms in clinical assessments, in particular to help disentangle personality disorder traits in youths.

[Hallucinations and borderline personality disorder: a review]

INTRODUCTION

Hallucinations constitute understudied symptoms in borderline personality disorders (BPD), which can be observed in about 30% of the patients, essentially in the auditory modality. Most of these experiences are transitory, triggered by intermittent stressors, but chronicity remains a major cause of concern. In order to better circumscribe hallucinations in BPD, we summarized the literature on this particular phenomenon.

METHODS

We conducted a review using Medline, Scopus and Google Scholar databases up to March 2013, using the following keywords combinations: "borderline personality disorder", "hallucinat*" and "psychotic symptoms". Papers were included in the review if they were published in an English or French language peer-reviewed journal; the study enrolled patients with BPD; and the diagnosis was made according to the Diagnostic and Statistical Manual (DSM) criteria. Fifteen studies published between 1985 and 2012, merging a total of 635 patients, were retained.

RESULTS

The hallucinatory experiences observed in BPD appeared phenomenologically similar to those described in the schizophrenia spectrum in terms of vividness, duration, spatial localization, beliefs about malevolence or omnipotence. Conversely, the hallucinatory content appeared more negative and potentially more distressful. Crucially, this literature search also revealed that these symptoms have long been regarded as "pseudo-hallucinations" (or "hallucination-like symptoms"). This concept was judged of poor scientific validity, inducing stigma for BPD patients in that it casts doubt on the authenticity of these experiences while disqualifying the related distress. This situation points out that research should focus more on understanding hallucinations in BPD than questioning their existence. Interestingly, recent comorbidity studies reopened a 40-year debate on the potential links that may exist between BPD and psychosis. Initially considered as a para-psychotic disorder, BPD was effectively redefined as an independent category by Otto F. Kernberg, leading to the DSM-III definition, excluding any psychotic symptom. However, hallucinations per se remain insufficient to diagnose schizophrenia, while comorbid substance use disorders as well as mood disorders, cannot explain all the hallucination occurrences in BPD. By referring to the "psychotic-reactivity-to-stress" framework, we proposed to understand hallucinations in BPD in relation to a hyperactivity of the hypothalamic-pituitary-adrenal axis and of the dopaminergic system under stress. Childhood trauma may have a central role in such a model. The prevalence of childhood trauma is high in BPD but this factor was also evidenced strongly linked with hallucinations in non-clinical populations. Comparisons are finally made and discussed between hallucinations occurring in BPD and those observed in posttraumatic stress disorder, another frequent comorbid disorder.

CONCLUSION

Almost a third of patients with BPD experiences hallucinations, and future studies will have to clarify the pathophysiology of this symptom, still poorly understood. Both the models of psychotic-reactivity-to-stress, as well as the role of childhood trauma in the context of a gene X environment interaction, appear to be promising cues for future research.

Borderline personality features and development of psychosis in an 'ultra high risk' (UHR) population: a case control study

AIMS

There is clinical uncertainty as to whether borderline personality disorder (BPD) traits in those with an 'at risk mental state' have an effect on the risk of 'transition' to psychosis. We aimed to investigate the relationship between baseline BPD features, risk of transition and type of psychotic disorder experienced.

METHOD

This is a case-control study of 'ultra high risk' (UHR) for psychosis patients treated at the clinic, between 2004 and 2007. 'Cases' were UHR individuals who made the 'transition' to full threshold psychotic disorder within 24 months; 'control' group was a matched UHR sample who had not developed a psychotic disorder at 24 months. Individuals were matched on time of entry to the clinic, age and gender. Diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV) BPD features were assessed from clinical assessments using a structured instrument (Structured Clinical Interview for DSM-IV Axis II Disorder for BPD (SCID-II BPD)). Psychosis diagnosis following transition was rated from the clinical files using the operational criteria in studies of psychotic illness (OPCRIT) computer algorithm. The number of BPD traits and number with full threshold BPD were compared in those who developed psychosis and those who did not.

RESULTS

We analysed data from 48 cases and 48 controls. There was no statistically significant difference in the rate of transition to psychosis for those with baseline full-threshold BPD, compared with those without BPD. The number of BPD traits or number with full threshold BPD did not differ by psychosis diagnosis grouping.

CONCLUSIONS

Co-occurring BPD or BPD features does not appear to strongly influence the risk of short-term transition to psychosis or the risk of developing a non-affective psychotic disorder in this population.

Borderline personality disorder and psychosis: a review

Early views of borderline personality disorder (BPD) were based on the idea that patients with this pathology were "on the border" of psychosis. However, more recent studies have not supported this view, although they have found evidence of a malevolent interpersonal evaluation and a significant proportion of BPD patients showing psychotic symptoms. For example, in one study, 24% of BPD patients reported severe psychotic symptoms and about 75% had dissociative experiences and paranoid ideation. Thus, we start with an overview regarding the prevalence of psychotic symptoms in BPD patients. Furthermore, we report findings of studies investigating the role of comorbidity (eg, post-traumatic stress disorder) in the severity and frequency of psychotic symptoms in BPD patients. We then present results of genetic and neurobiological studies comparing BPD patients with patients with schizophrenia or nonschizophrenic psychotic disorders. In conclusion, this review reveals that psychotic symptoms in BPD patients may not predict the development of a psychotic disorder but are often permanent and severe and need careful consideration by clinicians. Therefore, adequate diagnosis and treatment of psychotic symptoms in BPD patients is emphasized.

Subclinical hallucinations in adolescent outpatients: an outcome study

OBJECTIVE

We assessed the continued prevalence at one year and association with clinical variables of subclinical hallucinations ascertained at baseline in a cohort of adolescent outpatients referred to a specialized early psychosis service. We further assessed the prevalence of psychiatric disorders in adolescents presenting subclinical hallucinations.

METHOD

84 adolescent patients were sampled from a longitudinal, prospective study that assesses the course of clinical and neuropsychological measures in patients identified as at high clinical risk for psychosis. Subclinical hallucinations were measured using the Scale of Prodromal Symptoms (SOPS) with its companion interview manual (Structured Interview for Prodromal Symptoms, SIPS) [Miller, T.J., McGlashan, T.H., Woods, S.W., Stein, K., Driesen, N., Corcoran, C.M., Hoffman, R., Davidson, L., 1999. Symptom assessment in schizophrenic prodromal states. Psychiatr. Q. 70, 273-287; McGlashan, T.H., Miller, T.J., Woods, S.W., Rosen, J.L., Hoffman, R.E., Davidson, L., 2001. Structured Interview for Prodromal Syndromes (Version 3.0, unpublished manuscript). PRIME Research Clinic, Yale School of Medicine New Haven, Connecticut. ], and the Schizophrenia Proneness Instrument -Adult Version (SPI-A) [Schultze-Lutter, F., Addington, J., Ruhrmann, S., Klosterkötter, J., 2007. Schizophrenia Proneness Instrument (SPI-A). Giovanni Fioriti, Rome, Italy]. At one-year follow-up, only patients reporting subclinical hallucinations at initial assessment were studied.

RESULTS

Full remission of subclinical hallucinations occurred in over half and at least partial remission in two thirds of these patients at one-year follow-up. Mood disorders were present in 62.5% of adolescents with subclinical hallucinations at initial assessment. SOPS measures for depression, deficient attention and for unusual/delusional thought were significantly associated with subclinical hallucinations at baseline. However, sustained experience of subclinical hallucinations at one-year follow-up was only predicted by the global level of functioning at baseline, while cannabis abuse, psychiatric and psychopharmacological treatment were not predictors.

CONCLUSIONS

Subclinical hallucinations occur across a wide range of mental states in adolescents and show high rates of remission. Our results warrant that the clinical meaning of such phenomena needs to be carefully weighed against the specific developmental phenomena in this particular age range.

Pathways to psychosis: a comparison of the pervasive developmental disorder subtype Multiple Complex Developmental Disorder and the "At Risk Mental State"

BACKGROUND

The comparison of high-risk populations with different developmental pathways to psychosis may lend more insight into the heterogeneity of the manifestation of the psychotic syndrome, and possible differing etiological pathways.

AIM

To compare high-risk traits and symptoms in two populations at risk for psychosis, i.e. (1) help-seeking adolescents presenting with prodromal symptoms meeting the criteria for At Risk Mental State (ARMS), and (2) adolescents with Multiple Complex Developmental Disorder (MCDD), a PDD-NOS subtype characterized by severe, early childhood-onset deficits in affect regulation, anxieties, disturbed social relationships, and thought disorder.

METHOD

80 ARMS- and 32 MCDD-adolescents (12-18 years) were compared on prodromal symptoms (Structured Interview of Prodromal Symptoms, and Bonn Scale for the Assessment of Basic Symptoms-Prediction list), and autism traits (Social Communication Questionnaire). In addition, both high-risk groups were compared with 82 healthy controls on schizotypal traits (Schizotypal Personality Questionnaire-Revised).

RESULTS

Although the high-risk groups clearly differed in early developmental and treatment histories as well as autism traits, they did not differ with regard to schizotypal traits and basic symptoms, as well as disorganized and general prodromal symptoms. There were, however, group differences in positive and negative prodromal symptoms. Interestingly, 78% of the adolescents with MCDD met criteria for ARMS.

CONCLUSION

These findings suggest that children diagnosed with MCDD are at high risk for developing psychosis later in life, and support the notion that there are different developmental pathways to psychosis. Follow-up research is needed to compare the rates of transition to psychosis in both high-risk groups.

Drug-induced psychosis associated with crystalline methamphetamine

OBJECTIVE

A case of drug-induced psychosis related to crystalline methamphetamine is described, highlighting the phenomenology and relevant treatment.

RESULTS

A 44-year-old woman with borderline personality traits and severe drug dependence developed a protracted drug-induced psychosis related to chronic high-dose crystalline methamphetamine use. Complete resolution of symptoms occurred with antipsychotic medication and abstinence from methamphetamine. Rapid recurrence of symptoms occurred at a time of high stress associated with minimal methamphetamine use and cessation of low-dose quetiapine. Symptoms rapidly resolved with abstinence, quetiapine and reduction of stressors.

CONCLUSIONS

A drug-induced psychosis resembling paranoid schizophrenia can occur with repeated or high-dose use of methamphetamine. While this generally resolves rapidly with cessation of stimulant use, some cases of protracted drug-induced psychosis in vulnerable individuals have been documented. Behavioural sensitization can also occur, and neuroleptics may prevent the recurrence of further psychosis triggered by ongoing low-dose methamphetamine use.

Borderline personality disorder

Borderline personality disorder is a chronic psychiatric disorder characterized by marked impulsivity, instability of mood and interpersonal relationships, and suicidal behaviour that can complicate medical care. Identifying this diagnosis is important for treatment planning. Although the cause of borderline personality disorder is uncertain, most patients improve with time. There is an evidence base for treatment using both psychotherapy and psychopharmacology. The clinical challenge centres on managing chronic suicidality.

Is reported childhood sexual abuse associated with the psychopathological characteristics of patients who experience auditory hallucinations?

OBJECTIVE

The aim of this study was to determine whether reported childhood sexual abuse is related to the severity of symptoms in patients who experience auditory hallucinations.

METHOD

A sample of 26 adult male and females with psychotic disorders involving auditory hallucinations were interviewed and were asked to complete three self-report measures: the Dissociative Experiences Scale (DES-II and DES-taxon versions); the Beck Depression Inventory (BDI); and the Beliefs About Voices Questionnaire (BAVQ). They were also asked about any history of sexual abuse in childhood.

RESULTS

A history of childhood sexual abuse was reported by 10 of the 26 patients (38.5%), and was associated with higher levels of depression and dissociation, as well as being linked to a tendency to regard the voices as more malevolent. The same three features were all associated with the age at first reported abuse, with a younger age of first experience being related to higher levels of psychopathology in all instances.

CONCLUSIONS

These results require replication and refinement in future research, but indicate a need for greater attention to be paid to the possible role of childhood sexual abuse when understanding and treating auditory hallucinations.

The role of the parietal lobe in borderline personality disorder

Many patients with a diagnosis of borderline personality disorder describe multi-modal hallucinations. A likely cortical origin for multi-modal hallucinations is the inferior parietal lobule. Neuropsychological testing of borderline personality disorder reveals deficits of visuospatial capacity; a function which is also localised to the inferior parietal lobule. It is hypothesised that this brain area is likely to be dysfunctional in those patients with borderline personality disorder who have multi-modal hallucinations. A deficit in the inferior parietal lobe could plausibly explain a number of other clinical features; the gender dimorphism of this disorder, the lack of expressive gesture and the specific response to clozapine. More speculatively; the increased concern over this disorder over the past 40 years could result from the normal population showing an increase in functional ability in the parietal lobe, leaving patients with parietal deficits relatively more disabled.
