RESUMO

Objectives The ordinary, ongoing sense of personal existing, variously called higher order consciousness, mind, or self, is disintegrated, constricted and distorted in those who have suffered repetitive psychological traumata. Their speech has the form of a 'chronicle', literal and asymbolic. This paper offers a condensed rationale for a relational approach to this, so far, neglected problem. CONCLUSIONS: A restorative and generative kind of relatedness is 'natural', the propensity for it being given to us by our biological heritage. Its first form is a game between babies and caregivers, a 'proto-conversation'. Principles derived from this, and related developmental behaviours, guide a form of therapeutic relatedness consisting of an interactive, to-and-fro 'patterning' of verbal 'pictures', or analogues, of the subject's immediate experience. The analogue is the first form of symbol, the use of which is the hallmark of the human.

RESUMO

OBJECTIVE: To test the hypothesis that borderline personality disorder is a manifestation of a particularly right hemispheric disturbance, involving deficient higher order inhibition, and to consider the therapeutic implications of the findings. METHODS: A cohort of 17 medication free borderline patients were compared with 17 age and sex matched controls by means of a study of p3a, which reflects the activity of one of the two main generators of the P300 (P3) of the event-related-potential. P3b reflects the output of the other generator. P3a, an aspect of the attentional system, depends upon prefrontally connected neurocircuitry. P3b is underpinned by a particularly parietally connected neural system. Using an oddball paradigm, P3a was extracted from the responses to targets using a novel single trial analysis. RESULTS: In borderline patients, over homologous electrode sites, p3a amplitudes, but not latencies, were significantly larger in the right hemisphere compared with the left. The differences were most marked fronto-centrally. No such difference was shown in the control subjects. P3a at right hemisphere sites was significantly larger in borderline compared with control patients. There was no significant difference between the groups for the left hemisphere sites. CONCLUSIONS: The abnormally large amplitudes of P3a at right hemisphere sites in borderline patients together with the failure of habituation of P3a, are consistent with deficient inhibitory activity. Discussion of the findings suggest that they may reflect impeded maturation of the fronto-medial processing systems which, it is argued, may be a consequence of the typical early environment of those with the borderline condition. This suggestion leads to a consideration of optimal therapeutic behaviour in this condition, in particular for 'matching' or 'analogical' responsiveness.

RESUMO

OBJECT: To determine which constellation of clinical features constitutes the core of borderline personality disorder (BPD). METHOD: The criterion of endurance was used to identify the constellation of features which are most basic, or core, in borderline personality disorder. Two sets of constellations of DSM-III features were tested, each consisting of three groupings. The first set of constellations was constructed according to Clarkin's factor analysis; the second was theoretically derived. Broadly speaking, the three groupings concerned 'self', 'emotional regulation', and 'impulse'. Changes of these constellations were charted over one year in a comparison of the effect of treatment by the Conversational Model (n = 29) with treatment as usual (n = 31). In addition, measures of typical depression (Zung) were scored before and after the treatment period. The changes in the constellations were considered in relation to authoritative opinion. RESULTS: The changes in the two sets of constellations were similar. In the treatment as usual (TAU) group, 'self' endured unchanged, while 'emotional regulation' and 'impulse' improved. In the Conversational Model cohort, 'self' improved, 'emotional regulation' improved more greatly than the TAU group, while 'impulse' improved but not more than the treatment as usual group. Depression scores were not particularly associated with any grouping. CONCLUSIONS: A group of features including self/identity disturbance, emptiness and fear of abandonment may be at the core of BPD. Correlations between the three groupings and Zung scores favoured the view that the core affect is not typical depression. Rather, the central state may be 'painful incoherence'. It is suggested that the findings have implications for the refinement and elaboration of treatment methods in borderline personality disorder.

RESUMO

The harmful effect of borderline patients on their families is an important but relatively neglected aspect of outcome studies. This study concerns changes in perceived quality of relationships with partners and children of 24 patients suffering Borderline Personality Disorder (BPD) after 12 months of treatment with the Conversational Model (CM). They were compared to 21 parents with BPD receiving "Treatment as Usual" (TAU) from their referring clinicians for the same period. Both groups developed naturalistically giving the study a quasi-experimental design. The Social Adjustment Scale (SAS-SR) was administered on intake and again after 12 months. The subscales dealing with relationships with children, with partners and with the family unit were scored and compared between groups. It was found that the perceived relationships with children and partners improved significantly for the CM group but not for the TAU group.

RESUMO

People with borderline personality disorder (BPD) often describe a longstanding depression or dysphoria central to the disorder. The dimension of chronic inner dysphoria is reflected in the DSM criterion of "emptiness" and is demonstrated on self-report measures of depression. In this paper, we report on outcomes for patients with BPD treated with outpatient psychodynamic psychotherapy based on the Conversational Model. Data were collected using the Zung depression scale and the Westmead severity scale at 1 year and at 2 years from two groups of patients. One group had 1 year in psychotherapy, the other had 2 years in therapy. While general symptom scores improved steadily over time in the two-year group, gains for the one-year group tapered off in the second year. Change in depression scores continued at an unchanged rate in the second year for the two-year group compared to a leveling out of gains in the group treated for one year. Gains in general symptom scores were more substantial, suggesting that change in affect occurs more slowly than other symptomatic changes. Drawing upon our findings and those of others in the field, it appears that this slowness of affective change may reflect that patients with BPD have an inner world where predominant negative affectivity became established early in life in the context of disturbances of relatedness. This has implications for the appropriate duration of psychotherapeutic engagement with this group. We argue for more prolonged psychotherapy in this group, which is consistent with current understanding of processes of attachment and development.

RESUMO

A "vicious circle" hypothesis is put forward for the common kind of somatization which forms the basis of the DSM's "somatization disorder." Two compounding mechanisms are seen to be operative: (1) a failure of higher order inhibitory systems involved in the "medial pain system"; (2) amplification of stimulus intensity produced by the effect of attention. Attentional failure is produced not only by social factors but also by failure of sensory intensity modulation consequent upon (1). The argument focuses on data from borderline patients in whom the unusual prominence of pain may be due, at least in part, to incompetence of the "medial pain system." This is reflected in enlarged P3a components of the event-related potential suggesting diminished inhibitory function involving prefrontal connections. Two studies are briefly presented in summary form suggesting that somatization may be ameliorated by a form of therapy which focuses on "inner" material as a means of overcoming "stimulus entrapment."

RESUMO

OBJECTIVE: Stress, pain, injury, and psychological trauma all induce arousal-mediated changes in brain network organization. The associated, high level of arousal may disrupt motor-sensory processing and result in aberrant patterns of motor function, including functional neurological symptoms. We used the auditory oddball paradigm to assess cortical arousal in children and adolescents with functional neurological symptom disorder. METHOD: Electroencephalogram (EEG) data was collected in fifty-seven children and adolescents (41 girls; 16 boys, aged 8.5-18 years) with acute functional neurological symptoms and age- sex- matched controls during a conventional auditory oddball task. The high-resolution fragmentary decomposition technique was used to analyse the amplitude of event-related potentials (ERPs) to target tones at midline sites (Fz, Cz, and Pz). RESULTS: Compared to age- and sex-matched controls, and across all three midline sites, children and adolescents with functional neurological symptoms showed increased amplitude of all ERP components (P50, N100, P200, N200, and P300) (t-value range 2.28-8.20; p value-range 0.023 to < 0.001) to the emotionally-neutral auditory stimulus. CONCLUSIONS: Our findings add to a growing literature indicating that a baseline state of high arousal may be a precondition for generating functional neurological symptoms, a finding that helps explain why a range of psychological and physiological stressors can trigger functional neurological symptoms in some patients. Interventions that target cortical arousal may be central to the treatment of paediatric patients with functional neurological symptom disorder.

RESUMO

P3a and P3b event-related brain potentials to auditory stimuli were recorded for 17 unmedicated patients with borderline personality disorder, 17 matched healthy controls and 100 healthy control participants spanning five decades. Using high-resolution fragmentary decomposition for single-trial event-related potential analysis, distinctive disturbances in P3a in borderline personality disorder patients were found: abnormally enhanced amplitude, failure to habituate and a loss of temporal locking with P3b. Normative age dependencies from 100 controls suggest that natural age-related decline in P3a amplitude is reduced in borderline personality disorder patients and is likely to indicate failure of frontal maturation. On the basis of the theories of Hughlings Jackson, this conceptualization of borderline personality disorder is consistent with an aetiological model of borderline personality disorder.

RESUMO

OBJECTIVE: The aim of this study was to test, in terms of impulsivity, the hypothesis that borderline personality disorder "burns out" with age. METHOD: Linear regression analyses, with age as a predictor variable, were conducted on subsection scores of the Revised Diagnostic Interview for Borderlines (DIB-R) for 123 individuals with a diagnosis of borderline personality disorder who were accepted into an outpatient-based psychotherapy program. The subsection scores of the DIB-R allow quantification of the core features of the disorder: affective disturbance, relationship disturbance, cognitive disturbance, and impulsive behavior. RESULTS: Older patients with borderline personality disorder showed less impulsivity than younger patients, but there was no difference in terms of affect disturbance, identity disturbance, and interpersonal problems. CONCLUSIONS: The view that borderline personality disorder burns out with age is supported in terms of impulsivity.

RESUMO

BACKGROUND: BPD is a serious mental illness in which psychotherapy has been shown to improve patient outcomes and reduce the use of health services. In most studies of psychotherapy, lower use of health services has been taken to imply lower health service costs. However, the costs of psychotherapy can offset any cost savings due to reduced use of other health services. AIMS OF THE STUDY: To estimate the net costs of health service use in a group of BPD patients receiving intensive psychotherapy. METHODS: Data on use of inpatient hospital, emergency hospital, ambulatory care, diagnostic tests and medications were collected for the twelve months before psychotherapy and the twelve months after the completion of treatment. Cost estimates were developed using standardised unit costs. RESULTS: There was a saving of approximately $670,000 in health service use over the thirty patients compared to a cost of $130,000 for psychotherapy, giving a net cost saving of $18,000 per patient. Most of this was due to reduced hospital admissions. Cost saving was higher in those patients who were high users of hospital services. Sensitivity analyses were performed; overall, the findings consistently show a reduction in the cost of health services used. DISCUSSION: The group studied consisted of 30 patients and comprised a before/after design. Therefore it does not overcome criticisms of other work in this area, that is of observational studies and small sample sizes. Nonetheless, the results were based on detailed costing of service use, using conservative assumptions and subject to sensitivity analysis. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: The use of intensive psychotherapy in BPD patients who are high users of health services, particularly those who have had multiple hospital admissions, is probably warranted until more evidence is available. IMPLICATIONS FOR HEALTH POLICIES: There is little rigorous evidence on the effectiveness and cost-effectiveness of psychotherapy. BPD patients appear to generate high service costs so it is important to establish effective and cost-effective modes of treatment. IMPLICATIONS FOR FURTHER RESEARCH: Further research is warranted to establish accurate patterns of service use in BPD patients, and to identify those groups who will most benefit from intensive psychotherapy. erans.

RESUMO

This paper gives a brief outline of the Conversational Model which is among the best validated of currently employed psychotherapies. The theory is built around the idea that the central task of psychotherapy is to potentiate the emergence and amplification of that dualistic form of consciousness that William James called self. However, this state of mind cannot be acted upon as if it existed in isolation. Rather, it is part of an ecology that includes the form of relatedness that underpins it. No element of the ecology can change unless the other elements also change. Seen in this way, the form of relatedness is transformational. It is necessarily mediated by conversation consisting of more than its content, the simple transmission of information. The main point of the paper is that the form of the conversation manifests and constitutes not only a form of consciousness but also a form of relatedness. This conception provides a means of testing hypotheses of therapeutic action since it suggests that syntactical structuring, together with the other major elements of language, lexicon, and phonology, allow us to chart the waxings and wanings of personal being in the therapeutic conversation.

RESUMO

Experiential evidence suggests that the main features of spiritual experience are euphoria, and a feeling of the expansion and unification of consciousness. A way towards understanding this state and how it might arise comes from a consideration of a state in which these features are lacking. Such a state is borderline personality disorder, central to which is a "painful incoherence" that is not merely "psychological" but can be demonstrated neurophysiologically. The phenomena of the borderline syndrome can be understood as failure of proper maturation of the experience of "self," conceived as higher order consciousness in a notional hierarchy of consciousness. Spiritual experience is understood as a state "larger than self." Since both the achievement of a sense of the spirit and recovery from borderline personality disorder (BPD) involve an ascent in a hierarchy of consciousness, they may have a common basis. The approach to the development of self is derived from developmental observations which suggest that it depends upon a particular form of conversation, the first form of which is shown in the first months of life as a proto-conversation. It has the characteristics of an analogical relatedness. Symbolic play arising at the second year of life, shows a partial internalization of this relatedness. Symbolic play is accompanied by a quasi-inner conversation with an illusory other who is both self and the mothering figure. It is suggested that this is the embryonic form of the "conversations" of mystics in communion with self and God.

RESUMO

INTRODUCTION: Anomalies on probabilistic reasoning, theory of mind (ToM) tasks, and attributional biases have been found in delusional people. Delusions are also effectively modified by cognitive behavioural therapy (CBT). We sought to examine whether CBT reduces delusional conviction by changing such general reasoning anomalies. METHOD: Sixteen patients commenced an 8-11 week CBT programme that targeted their delusions. Probabilistic reasoning, attributional biases, and ToM were assessed pre- and post-treatment. Delusional conviction, preoccupation, and distress were rated at each session. Pretreatment task performances were compared to norms. Repeated measures analyses compared pre- and posttreatment task performances and ratings of delusions. Correlational analyses were used to identify factors associated with reduced delusional conviction. RESULTS: At baseline, 11 patients showed some form of abnormal probabilistic reasoning, 13 excessive attributional biases, and 13 defective ToM compared to norms. Fourteen patients completed the CBT programme and showed significant reductions in delusional conviction and preoccupation. Despite some inconsistent evidence of improvement in verbal ToM tasks, reasoning styles in these 14 patients were largely unchanged by CBT. CONCLUSION: Reasoning anomalies associated with delusions in this sample mark a vulnerability that persists and is independent of the effectiveness of CBT.

RESUMO

This article investigates the pattern of temperament for patients with borderline personality disorder and the impact of psychotherapeutic treatment on temperamental variables. A cohort of patients treated in the Westmead Borderline Personality Disorder Psychotherapy research project completed the Tridimensional Personality Questionnaire. All patients had a diagnosis of borderline personality disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition, criteria. This group scored highly on novelty-seeking and harm avoidance scales and moderately on reward dependence. There was a significant reduction in harm avoidance after 12 months of psychotherapy with a further reduction after 2 years in therapy. Although at variance with Cloninger's original prediction of low harm avoidance in histrionic and borderline patients, results are consistent with other studies in this patient group. The paradox of "self-harmers" scoring highly on harm avoidance may be explained by recognition of the intensity of "psychic pain" in this group. Self-harming behaviors may frequently be motivated by avoidance of a "greater harm" in terms of the inner psychic reality for these patients. Reduction in harm avoidance with psychotherapy could suggest an impact of treatment on temperament or may indicate that the harm avoidance construct is influenced by state variables such as mood.

RESUMO

Recent work has lead to a greater degree of optimism in the treatment of borderline personality disorder (BPD). This study looks at a group of patients with BPD treated with outpatient psychotherapy using the conversational model of Hobson and Meares. The study group is compared, first, with the original cohort previously reported by Stevenson and Meares [Stevenson J, Meares R. An outcome study of psychotherapy for patients with borderline personality disorder. Am J Psychiatry 1992;149(3):358-62] and, second, with a wait-list "treatment-as-usual" control group. Patients were recruited well after initiation of the program and, hence, can be seen as a group treated under more usual clinical conditions rather than as a cohort subject to the initial wave of research enthusiasm. Subjects were rated at baseline and 12 months on a range of symptomatic, functional, and objective measures. The rate and degree of improvement in the later cohort are very similar to the original 1992 cohort and significantly greater than what is found in the treatment-as-usual controls. We believe that this is the first replication study demonstrating success in treating patients with BPD using an established form of individual psychodynamic therapy delivered in an outpatient setting.

RESUMO

OBJECTIVE: Symptoms of borderline personality disorder (BPD) may reflect distinct breakdowns in the integration of posterior and frontal brain networks. We used a high temporal resolution measure (40-Hz gamma phase synchrony) of brain activity to examine the connectivity of brain function in BPD. METHODS: Unmedicated patients with BPD (n = 15) and age-and sex-matched healthy control subjects (n = 15) undertook a task requiring discrimination of salient from background tones. In response to salient stimuli, the magnitude and latency of peak gamma phase synchrony for early (0-150 ms post stimulus) and late (250-500 ms post stimulus) phases were calculated for frontal and posterior regions and for left and right hemispheres. We recorded skin conductance responses (SCRs) and reaction time (RT) simultaneously to examine the contribution of arousal and performance. RESULTS: Compared with controls, patients with BPD had a significant delay in early posterior gamma synchrony and a reduction in right hemisphere late gamma synchrony in response to salient stimuli. Both SCR onset and RT were also delayed in BPD, but independently from differences in synchrony. The delay in posterior synchrony was associated with cognitive symptoms, and reduced right hemisphere synchrony was associated with impulsivity. CONCLUSIONS: These findings suggest that distinct impairments in the functional connectivity of neural systems for orienting to salient input underlie core dimensions of cognitive disturbance and poor impulse control in BPD.

RESUMO

Facial expressions of fear are universally recognized signals of potential threat. Humans may have evolved specialized neural systems for responding to fear in the absence of conscious stimulus detection. We used functional neuroimaging to establish whether the amygdala and the medial prefrontal regions to which it projects are engaged by subliminal fearful faces and whether responses to subliminal fear are distinguished from those to supraliminal fear. We also examined the time course of amygdala-medial prefrontal responses to supraliminal and subliminal fear. Stimuli were fearful and neutral baseline faces, presented under subliminal (16.7 ms and masked) or supraliminal (500 ms) conditions. Skin conductance responses (SCRs) were recorded simultaneously as an objective index of fear perception. SPM2 was used to undertake search region-of-interest (ROI) analyses for the amygdala and medial prefrontal (including anterior cingulate) cortex, and complementary whole-brain analyses. Time series data were extracted from ROIs to examine activity across early versus late phases of the experiment. SCRs and amygdala activity were enhanced in response to both subliminal and supraliminal fear perception. Time series analysis showed a trend toward greater right amygdala responses to subliminal fear, but left-sided responses to supraliminal fear. Cortically, subliminal fear was distinguished by right ventral anterior cingulate activity and supraliminal fear by dorsal anterior cingulate and medial prefrontal activity. Although subcortical amygdala activity was relatively persistent for subliminal fear, supraliminal fear showed more sustained cortical activity. The findings suggest that preverbal processing of fear may occur via a direct rostral-ventral amygdala pathway without the need for conscious surveillance, whereas elaboration of consciously attended signals of fear may rely on higher-order processing within a dorsal cortico-amygdala pathway.

RESUMO

BACKGROUND: Borderline personality disorder (BPD) is a serious mental illness. Due to scepticism about the effectiveness of its treatment, the care of these patients is neglected. In this study we evaluated the effect of treatment 5 years after its ending, of patients with BPD. METHOD: Thirty subjects were treated twice weekly for 1 year by psychotherapy based on the 'Conversational Model' of Hobson. Outcome measures included time in hospital, number of episodes of violence and self-harm, number of medical appointments, drug use and work history. A 'morbidity budget' made up of these items was collated for the year before treatment, the year following treatment, and for the year preceding the 5-year follow-up. Additional measures included DSM-III criteria and a self-report of symptoms. These outcomes were compared to a hypothetical natural history of BPD constructed from the DSM scores of 150 borderline patients aged between 18 and 52 years. RESULTS: Except for one measure, the improvements evident 1 year following treatment were maintained 4 years later. This improvement was not predicted by the hypothetical natural history. CONCLUSION: A particular form of treatment of BPD has relatively long-lasting, beneficial effects.

RESUMO

A case series of 10 patients with a diagnosis of borderline personality disorder (BPD) presenting with auditory hallucinosis is examined. In this series, the hallucinations were persistent, longstanding, and a significant source of distress and disability. Extrapolating from this series to our sample of 171 patients with BPD suggests that a form of auditory hallucinosis may occur in almost 30% of this population. The failure to emphasize this phenomenon in current systems of classification risks misdiagnosis or inappropriate treatment. Use of terms such as pseudohallucination or quasi hallucination dismisses the phenomenon as unimportant or as "not real." There is an emerging literature on the frequency of hallucinosis among nonpatients. A basis for understanding different forms of hallucination is discussed with reference to the concept of "normativity." We propose a nomenclature for hallucinosis that is expressed in positive terms, reflecting the clinical significance of the phenomenon in different contexts: (1) normative hallucinosis, (2) traumatic-intrusive hallucinosis (as in our series), (3) psychotic hallucinosis, and (4) organic hallucinosis.

RESUMO

OBJECTIVE: To draw attention to the absence of a concept of personal existence in standard psychiatric approaches to mental illness. METHOD: To sketch a shift in Western consciousness which occurred suddenly before World War I, involving a banishment of such notions as self and the awareness of inner life from the discourse of psychiatry, psychology and philosophy, leaving a fundamental vacancy at the heart of these disciplines. RESULTS AND CONCLUSION: The positivist-behaviourist hegemony of the twentieth century involved an implicit devaluation of that which is essentially human. The influence of this tradition brings with it the risk of an understanding and treatment of mental illness which leaves out issues at the core of humanity. I suggest we need to recover something of the manner of thinking of the great figures in psychological thought who were writing before the rise of behaviourism and who were contributing to the origins of dynamic psychiatry. A study of the phenomena of human consciousness was central to their work. Main figures mentioned include: Hughlings Jackson, the great neurologist who considered a career in philosophy; Pierre Janet, a philosopher turned psychiatrist; and William James, a physiologist who became a psychologist and philosopher.
