Dimensions underlying outcome criteria in bipolar I disorder

OBJECTIVE: Various subjective and objective criteria are used to assess outcome in bipolar disorder. In this study, we explored to what extent they reflect distinct categories and whether underlying dimensions can be identified. PATIENTS AND METHODS: One-hundred and twenty-one subjects with at least three episodes of bipolar I disorder (DSM-IV) were assessed on average 4.8 years after hospitalization. We assessed 14 variables reflecting different outcome criteria including subjective quality of life (SQOL), self-rated and observer-rated psychopathology, and functioning and disability. A principal component analysis was computed across all outcome variables. Identified dimensions were correlated with sociodemographic characteristics, illness history, premorbid adjustment and personality traits. RESULTS: Three outcome dimensions were identified, i.e. a 'general subjective', a 'functioning/disability' and a 'manic/psychotic symptoms' dimension. Together they explain 69% of the total variance. The 'general subjective' dimension consists of SQOL scales and self-rated depressive symptoms. It is associated with comorbid anxiety disorders and personality disorders, high neuroticism and not having been in hospital in the last year. The 'functioning/disability' dimension comprises of criteria reflecting negative symptoms, disability and low functioning. It is associated with more prior illness episodes and low premorbid adjustment. The 'manic/psychotic symptoms' dimension consists of observer-rated manic and positive psychotic symptoms. It is correlated with not currently taking a specific medication. LIMITATIONS: Cross-sectional design with a limited sample size. CONCLUSION: The findings indicate that outcome criteria in bipolar I disorder can be grouped into three distinct dimensions reflecting (1) subjective appraisals, (2) functioning/disability and (3) manic/psychotic symptoms. While measurement of psychotic/manic symptoms has become a matter of course, until now few studies have assessed disability or subjective appraisal in bipolar illness. Therefore important aspects of bipolar illness might be overseen. For a better understanding, we suggest that longitudinal studies of bipolar I disorders should consider all three dimensions of outcome and measure them separately.     

Lamotrigine for the treatment of bipolar disorder: a clinical case series.

BACKGROUND: Recently, a number of new agents have become available to treat bipolar disorder, however many patients may not respond fully even when used in combination. Early reports in epilepsy studies suggested mood-related effects of lamotrigine treatment, as have preliminary reports in bipolar patients. METHODS: Seventeen patients meeting DSM-IV criteria for bipolar I (n = 9) or bipolar II (n = 8) disorder displaying affective symptoms and a past history of inadequate response or tolerability to at least two standard mood stabilizing agents were recruited through the Stanley Foundation Bipolar Network and treated with the new anticonvulsant lamotrigine in an add-on, open-label study. Response to therapy was assessed using the Clinical Global Impression Scale modified for bipolar disorder. RESULTS: The mean dose of lamotrigine was 187+/-157 mg/day (range 50-600 mg/day) for a mean duration of 159+/-109 days (range 14-455 days). Eleven (65%) patients were rated as very much or much improved. Lamotrigine was well tolerated, and may have mood stabilizing and antidepressant properties in some patients with bipolar disorder. LIMITATIONS: The study is hypothesis generating because it was uncontrolled and open. Controlled studies are warranted. CONCLUSIONS: This preliminary report supports clinical improvement for both mood cycling and depression in patients with bipolar disorder treated with lamotrigine.     

Lamotrigine as a promising approach to borderline personality: an open case series without concurrent DSM-IV major mood disorder.

BACKGROUND: Borderline personality disorder (BPD) has long defined definitive treatment. Such failure is reflected in repeated suicidal crises, often associated with dysphoric symptoms of a chronic fluctuating nature, whose labile intermittent character does suggest a subthreshold bipolar depressive mixed state. For all these reasons, we hypothesized that the anticonvulsant lamotrigine, touted to be a mood stabilizer with antidepressant properties, might be uniquely beneficial for these patients. METHODS: From a base rate of about 300 patients in a community mental health center, we identified eight patients meeting seven or more of the DSM-IV criteria for BPD without concurrent major mood disorders. All patients presented with history of severe suicidal behavior, hostile depression and/or labile moods, stimulant and alcohol abuse, as well as multiple unprotected sexual encounters; one patient was actually HIV positive. All had failed previous trials with different antidepressants and mood stabilizers. All current medications were gradually withdrawn--and when necessary--patients kept on a low dose of a conventional neuroleptics for a few weeks, while lamotrigine was being gradually introduced in 25-mg weekly increments until the patient responded (up to 300 mg/day maximum). RESULTS: Consistent with previous work by us and others, bipolar family history could be documented in three of eight BPD patients, and worsening on antidepressants in four of eight, providing indirect support to our conceptualization of BPD as a bipolar variant. One patient developed a rash on 25 mg and was dropped from the lamotrigine trial, while another patient was noncompliant. Three who failed lamotrigine, subsequently responded, respectively, to sertraline, lithium-thioridazine combination, and valproate. The remaining three patients showed a robust response to lamotrigine, ranging from 75 to 300 mg/day: their functioning jumped from a mean baseline DSM-IV GAF score in the 40's to the 80's during 3-4 months. Among all responders impulsive sexual, drug-taking and suicidal behaviors disappeared and no longer met the criteria for BPD. At an average follow-up of 1 year, they no longer meet criteria for BPD. LIMITATIONS: Open uncontrolled results on a small number of patients in a tertiary care center may not generalize to BPD patients at large. CONCLUSIONS: Overall, the BPD response to pharmacotherapy in the present case series was 75%. The fact that five of six pharmacotherapy responders required mood stabilizers, argues against the prevalent view that the depressions of borderline patients belong to unipolarity. Of BPD patients who completed the trial, 50% achieved sustained remission from their personality disorder with lamotrigine monotherapy. The dramatic nature of the response in patients refractory to all previous medication trials and maintenance of a robust response over 1 year, argue against a placebo effect. Controlled systematic investigation of lamotrigine in BPD is indicated.     

Borderline personality disorder characteristics in young adults with recurrent mood disorders: a comparison of bipolar and unipolar depression

BACKGROUND: In young adults it can be difficult to differentiate between an early bipolar illness and borderline personality disorder. There are considerable areas of clinical overlap between cyclothymic temperament, bipolar-spectrum disorders and borderline characteristics. The aim of this study was to measure borderline characteristics in young adults during an index depressive episode and to compare three diagnostic groups: DSM-IV bipolar affective disorder (BPAD); bipolar spectrum disorder (BSD); and DSM-IV recurrent major depressive disorder (MDD). METHODS: Eighty-seven young adults with a current episode of major depression and at least one previous episode of depression were recruited from consecutive referrals to a psychiatric clinic. Diagnoses were based on the Structured Clinical Interview for DSM-IV (SCID-1) and recently proposed structured diagnostic criteria for BSD. All patients also completed the borderline questions from the screening questionnaire of the International Personality Disorders Examination (IPDE). RESULTS: Diagnostically, the cohort of 87 patients divided into three groups: 14 with BPAD; 27 with BSD; and 46 with MDD. None of the subjects fulfilled DSM-IV or ICD-10 diagnostic criteria for personality disorder and all three groups were well matched in terms of age, gender distribution, ethnicity, socioeconomic and educational status, age at onset of illness, and severity of index depressive episode. Both of the bipolar-depressed groups reported significantly higher median levels of borderline characteristics than the MDD group (p<0.0001). Three of the borderline characteristics emerged as potentially useful in differentiating bipolar depression from unipolar depression: 'I've never threatened suicide or injured myself on purpose' (sensitivity=0.93; positive predictive value [PPV]=56.7); 'I have tantrums or angry outbursts' (sensitivity 0.66; PPV=65.6%); and 'Giving in to some of my urges gets me into trouble' (sensitivity=0.76; PPV=59.6%). LIMITATIONS: All of the subjects were recruited from a university health service clinic and as such are unlikely to be representative of patients from more diverse socio-economic backgrounds. No structured diagnostic assessment of personality disorder was administered. The diagnostic criteria for BSD are not yet fully validated. CONCLUSIONS: Young adults with bipolar depression exhibit significantly higher levels of borderline personality pathology than those with unipolar depression. Those borderline screening questions that reflect cyclothymic characteristics or depressive mixed states may be of practical use to clinicians in helping to differentiate between bipolar depression and unipolar depression in young adults.     

Divalproex sodium in sex offenders with bipolar disorders and comorbid paraphilias: an open retrospective study

BACKGROUND: This study evaluated divalproex response in sex offenders with a bipolar disorder. METHODS: We reviewed the records of all sex offenders who participated in a residential rehabilitative program who received divalproex for treatment of a bipolar disorder. Patients' mood symptoms and, when present, comorbid paraphilic symptoms, were retrospectively assessed using the CGI severity scale. RESULTS: Sex offenders displayed significant improvement in manic symptoms with divalproex treatment. However, there was no significant improvement in paraphilic symptoms in the subset of patients admitting to these symptoms. CONCLUSION: Divalproex may be effective for manic symptoms in sex offenders with a bipolar disorder. However, for bipolar sex offenders with comorbid paraphilias, the drug may not be effective for paraphilic symptoms. LIMITATIONS: This study was limited by its retrospective, open-label design, lack of systematic means of assessing manic and paraphilic symptoms, and small sample size. CLINICAL RELEVANCE: Divalproex may be a helpful adjunct in the treatment of the subset of sex offenders who have a bipolar disorder.     

Axis I and II comorbidity in a large sample of patients with obsessive-compulsive disorder

Background: No study has reported yet on the prevalence of both comorbid DSM-IV axis I and personality disorders in a large cohort of OCD patients, and little is known about differences in clinical characteristics between OCD patients with and without comorbid symptoms. Objective: To examine the cross-sectional prevalence of comorbid DSM-IV axis I, and personality disorders in a population of patients with primary obsessive–compulsive disorder (OCD). Method: 420 outpatients with OCD were evaluated for comorbid pathology, demographic, and clinical characteristics. Results: Forty-six percent of the patients were diagnosed with a comorbid disorder. Twenty-seven percent met the criteria for at least one comorbid axis I disorder, 15.6 percent for a comorbid personality disorder, and 20.4 percent for both a comorbid axis I disorder and a personality disorder. Limitations: A limitation of the current study is that the sample was drawn from a psychiatric department specialised in anxiety disorders, which might have underestimated the rate of comorbid diagnoses. Conclusion: Comorbid diagnoses occur less frequently than would be expected on the basis of comparable comorbidity studies in OCD. Associated axis I comorbidity did not affect clinical severity of OCD, but was related to higher levels of depression and anxiety, whereas axis II comorbidity impaired to a higher extent the overall functioning.     

Is comorbid borderline personality disorder in patients with major depressive episode and bipolarity a developmental subtype? Findings from the international BRIDGE study

BackgroundThe nature of the relationship between bipolar disorder (BD) and borderline personality disorder (BPD) is controversial. The aim of this study was to characterize the clinical profile of patients with BD and comorbid BPD in a world-wide sample selected during a major depressive episode (MDE).MethodsFrom a general sample of 5635 in and out-patients with an MDE, who were enrolled in the multicenter, multinational, transcultural BRIDGE study, we identified 2658 subjects who met bipolarity specifier criteria. Bipolar specifier patients with (BPD+) and without (BPD?) comorbid BPD were compared on diagnostic, socio-demographic, familial and clinical characteristics.Results386 patients (14.5%) met criteria for BPD. A diagnosis of BD according to DSM-IV criteria was significantly more frequent in the BPD? than in BPD+, while similar rates in the two groups occurred using DSM-IV-Modified criteria. A subset of the BD criteria with an atypical connotation, such as irritability, mood instability and reactivity to drugs were significantly associated withthe presence of BPD. BPD+ patients were significantly younger than BPD? bipolar patients for age, age at onset of first psychiatric symptoms and age at first diagnosis of depression. They also reported significantly more comorbid Alcohol and Substance abuse, Anxiety disorders, Eating Disorder and Attention Deficit Hyperactivity Disorder. In comparison with BPD?, BPD+ patients showed significantly more psychotic symptoms, history of suicide attempts, mixed states, mood reactivity, atypical features, seasonality of mood episodes, antidepressants induced mood lability and irritability, and resistance to antidepressant treatments.LimitationsCenters were selected for their strong mood disorder clinical programs, recall bias is possible with a cross-sectional design, and participating psychiatrists received limited training.ConclusionsWe confirm in a large sample of BD patients with MDE the high prevalence of patients who meet DSM-IV criteria for BPD. Further prospective researches should clarify whether the mood reactivity and instability captured by BPD DSM-IV criteria are distinguishable from the subjective mood of an instable, dysphoric, irritable manic/hypomanic/mixed state or simply represent a phenotypic variant of BD, related to developmental factors.     

The initial prodrome to bipolar affective disorder: prospective case studies

BACKGROUND: The initial prodrome to bipolar disorder has received very little attention to date, with most of the available data only addressing the prodrome to relapse. This study presents several prospective case studies of the initial prodrome to bipolar affective disorder. METHODS: Three patients are presented who developed bipolar disorder during their treatment at the Personal Assessment and Crisis Evaluation Clinic (PACE). They were prospectively interviewed over a 12-month period using standard clinical research interviews. RESULTS: These patients met the criteria for bipolar disorder by the end of the treatment period. Depressive symptoms were the main reason for their first clinical presentation, with mania developing at a later date. Other comorbidities were observed before they were diagnosed with bipolar disorder. LIMITATIONS: The generalisability of our findings was constrained because of the small sample size. Furthermore, our findings are likely to be influenced by the intake criteria used at PACE, a clinic that primarily aims at identifying patients at risk of psychosis rather than bipolar disorder. CONCLUSION: Our study provides information about the initial prodrome to bipolar disorder, which has previously been neglected in research studies. We found there were no prodrome features that clearly distinguished between patients who go on to develop bipolar disorder and those who develop schizophrenia. We hope our prospective data will be the starting point for subsequent studies, with the aim of applying these findings to developing suitable preventative interventions for bipolar disorder.     

Is bipolar disorder still underdiagnosed? Are antidepressants overutilized?

BACKGROUND: Previous studies have suggested that bipolar disorder may be underdiagnosed, and that antidepressants may be over-utilized in its treatment. METHODS: Consecutively admitted patients (n =48) diagnosed with DSM-IV bipolar disorder, type I, (n = 44) or schizoaffective disorder, bipolar type, (n = 4) were interviewed systematically and their charts were reviewed to confirm diagnosis before admission. They were then treated according to systematic structured interview diagnoses. These data reflect the changes in diagnoses and treatment. RESULTS: 40% (19/48) were identified with previously undiagnosed bipolar disorder, all previously diagnosed with unipolar major depressive disorder. A period of 7.5+/-9.8 years elapsed in this group before bipolar diagnosis was made. Antidepressant use was high on admission (38%) and was reduced with acceptable treatment response rates. The adjunctive use of risperidone appeared to be a good treatment alternative. LIMITATIONS: While diagnoses were made prospectively, treatment response was assessed retrospectively, and was based on non-randomized, naturalistic therapy. CONCLUSIONS: Systematic application of DSM-IV criteria identified previously undiagnosed bipolar disorder in 40% of a referred population of patients with mood disorders, all previously misdiagnosed as unipolar major depressive disorder. Antidepressants appeared overutilized and risperidone was an effective alternative adjunctive therapy agent.     

Personality disorders and depression

BACKGROUND: Personality disorders (PDs) were assessed among depressed out-patients by clinical interview before and after antidepressant treatment with fluoxetine to assess the degree of stability of PD diagnoses and determine whether changes in PD diagnoses across treatment are related to the degree of improvement in depressive symptoms. METHOD: Three hundred and eighty-four out-patients (55% women; mean age = 39.9 +/- 10.5) with major depressive disorder (MDD) diagnosed with the SCID-P were enrolled into an 8 week trial of open treatment with fluoxetine 20 mg/day. The SCID-II was administered to diagnose PDs at baseline and endpoint. RESULTS: A significant proportion (64%) of our depressed out-patients met criteria for at least one co-morbid personality disorder. Following 8 weeks of fluoxetine treatment, there was a significant reduction in the proportion of patients meeting criteria for avoidant, dependent, passive-aggressive, paranoid and narcissistic PDs. From baseline to endpoint, there was also a significant reduction in the mean number of criteria met for paranoid, schizotypal, narcissistic, borderline, avoidant, dependent, obsessive-compulsive, passive aggressive and self-defeating personality disorders. While changes in cluster diagnoses were not significantly related to improvement in depressive symptoms, there were significant relationships between degree of reduction in depressive symptoms (percentage change in HAM-D-17 scores) and degree of change in the number of criteria met for paranoid, narcissistic, borderline and dependent personality disorders. CONCLUSIONS: Personality disorder diagnoses were found to be common among untreated out-patients with major depressive disorder. A significant proportion of these patients no longer met criteria for personality disorders following antidepressant treatment, and changes in personality disorder traits were significantly related to degree of improvement in depressive symptoms in some but not all personality disorders. These findings suggest that the lack of stability of PD diagnoses among patients with current MDD may be attributable in part to a direct effect of antidepressant treatment on behaviours and attitudes that comprise PDs.     

Prevalence and comorbidity of dysthymic disorder among psychiatric outpatients.

We investigated prevalence and comorbidity of DSM-III dysthymic disorder in a psychiatric outpatient clinic. Seventy-five consecutive outpatients received structured interviews. Prevalence of dysthymic disorder was 36% in the consecutive sample. Thirty-four dysthymic and 56 non-dysthymic patients were compared for comorbidity. Dysthymic subjects were more likely to meet criteria for major depression, social phobia, and avoidant, self-defeating, dependent, and borderline personality disorders. Dysthymic disorder was usually of early onset, predating comorbid disorders, and had often not received adequate antidepressant treatment. These results help define dysthymic disorder as prevalent, usually predating axis I comorbidity, and associated with particular axis II diagnoses.     

Comorbid disorders in patients with bipolar disorder and concomitant substance dependence

OBJECTIVE: Substance dependence is common in bipolar disorder and is associated with an increase in Axis I and II comorbidity. Little research has compared the relative rates of comorbidity among bipolar patients with dependence on different substances. METHODS: The Mini International Neuropsychiatric Interview (MINI) was used to assess 166 outpatients involved in one of three clinical trials of medications for bipolar disorder and substance dependence. Patients had concurrent alcohol dependence, cocaine dependence, or both conditions. RESULTS: Generalized anxiety disorder and current depressed mood were significantly more common in bipolar patients with alcohol dependence than bipolar patients with cocaine dependence. Those with cocaine dependence had significantly higher rates of post-traumatic stress disorder and antisocial personality disorder and were more likely to present in a mixed mood state than patients dependent on alcohol. Cocaine ENC dependent patients were more likely than alcohol dependent patients to have Bipolar I relative to Bipolar II. LIMITATIONS: This is a retrospective, cross-sectional data analysis using the MINI for diagnosis. CONCLUSIONS: Cocaine dependence and alcohol dependence were associated with different clinical features and comorbid disorders in bipolar patients. The results may help confirm the validity of integrative models of mood, behavioral, anxiety, and personality disorders. Further studies on the causal relationship between substance dependence and concurrent and lifetime Axis I disorders for patients with bipolar disorders are indicated.     

Comorbid bipolar disorder and premenstrual dysphoric disorder: real patients, unanswered questions

Large-scale clinical and epidemiological studies suggest a link between bipolar disorder (BD) and premenstrual dysphoric disorder (PMDD). However, smaller studies using prospective charting failed to find this association. Here, we report three cases of individuals with BD and comorbid PMDD who responded successfully to adjunctive contraceptive agents in the management of their severe premenstrual symptoms. While controlled trials investigating pharmacological and non-pharmacological treatments are awaited, adjunctive treatment of contraceptive agents and mood stabilizers may be an option in the treatment of comorbid BD and PMDD.     

Sustained remission with lamotrigine augmentation or monotherapy in female resistant depressives with mixed cyclothymic-dysthymic temperament

BACKGROUND: The treatment of bipolar depression remains problematic. Lamotrigine has been shown in randomized controlled studies to be efficacious in preventing bipolar depression and rapid cycling states. METHODS: Twenty-four women with cyclothymic temperament and refractory depression were recruited from four outpatient sites (three primary care and one psychiatric) and treated with lamotrigine in a naturalistic, open-label study. Temperament was determined by responses on the TEMP-A self-rating scale. Eighteen (75%) of these cyclothymic patients also scored high on the depressive temperament. Eighteen (75%) met DSM-IV criteria for bipolar II disorder. In two thirds of the cases, lamotrigine was add-on therapy to an antidepressant. Response to therapy was assessed using the DSM-IV Global Assessment of Functioning (GAF). LIMITATIONS: This study was naturalistic in design, without controls or blinds. RESULTS: Of the 23 patients who remained in the study, 16 (70%) had significant, sustained responses. Of these 16, 12 (75% of responders, 52% of the total) had remissions (GAF > 80) sustained longer than 12 months. Robust, sustained responses to lamotrigine monotherapy were seen in 4 patients (17%). Seven patients (30%) received no apparent benefit from lamotrigine. CONCLUSIONS: Lamotrigine induced prolonged illness remissions in a substantial number of female patients whose symptoms were both complex and refractory. Most manifested high scores on the cyclothymic and depressive temperaments, and prior refractoriness to multiple antidepressant and antidepressant/mood stabilizer combinations, before remitting with lamotrigine augmentation or monotherapy.     

A momentary assessment study of the reputed emotional phenotype associated with borderline personality disorder

SUMMARY BACKGROUND: Stress is postulated to play an essential role in the expression of core borderline symptoms. However, the phenomenology of stress reactivity in borderline personality disorder remains unclear. The current study investigated the phenomenology of stress sensitivity in borderline personality disorder in the flow of daily life and compared this with stress sensitivity in patients suffering from psychotic disorders, a group so far known to report the largest reactivity to stress.MethodA total of 44 borderline patients, 42 patients with psychotic disorder and 49 healthy controls were studied with the Experience Sampling Method (a structured diary technique assessing current context and mood in daily life) to assess: (1) appraised subjective stress related to daily events and activities; and (2) emotional reactivity conceptualized as changes in positive and negative affect. RESULTS: Multilevel regression analysis revealed that subjects with borderline personality disorder experienced significantly more emotional reactivity to daily life stress compared with both patients with psychosis and healthy controls, as evidenced by a larger increase in negative affect and a larger decrease in positive affect following stress.ConclusionThese results are the first to ecologically validate the incorporation of stress reactive symptoms in the diagnosis of borderline personality disorder. Borderline patients continually react stronger than patients with psychosis and healthy controls to small disturbances that continually happen in the natural flow of everyday life. Altered emotional stress reactivity may define borderline personality disorder.     

Clinical characteristics of bipolar disorder in very young children

BACKGROUND: Clinical information about bipolar disorder (BPD) in preschool-age (3-7 years old) children is extremely limited. This study examined clinical presentations, applicability of the DSM-IV diagnostic criteria, comorbidity, recovery and relapse rates, as well as some treatment strategies used in the management of BPD in preschoolers. METHODS: The charts of 26 outpatient children, ages 3-7, refereed to a child psychiatry outpatient clinic with mood and behavioral symptoms, were retrospectively reviewed. RESULTS: The majority of the patients were referred with the tentative diagnosis of ADHD but the most common diagnoses made by child and adolescent psychiatrists at the time of initial evaluation were BPD NOS (61.5%), followed by BPD I (26.9%), and mood disorder NOS (23.1%). Thirty-eight percent of the patients had one or more comorbid diagnoses. The most common presenting symptoms were irritability (84.6%) and aggression (88.5%). The most widely prescribed class of medications after diagnosis in the clinic was atypical antipsychotics and mood stabilizers. Twenty-six percent of the patients were treated with a combination of atypical antipsychotics and mood stabilizers. LIMITATIONS: Retrospective design; small sample size; lack of a comparison group. CONCLUSIONS: The course of BPD with onset in preschool years is complicated with high recovery and relapse rates. The questions of development of age-appropriate diagnostic criteria, long-term prognosis and treatment strategies used in this population require further intensive investigation.     

Vulnerable narcissism as beneficial factor for the therapeutic alliance in borderline personality disorder

Evidence suggests that narcissism and borderline personality disorder are associated with each other. This naturalistic study investigated the predictive value of grandiose and vulnerable narcissism on the development of the therapeutic alliance in short-term psychodynamic treatment across 12 weeks. The sample consisted of 99 patients with borderline personality disorder. Narcissism was assessed with the Pathological Narcissism Inventory at treatment onset. The therapeutic alliance was rated with the Scale to Assess Therapeutic Relationships by both patient and therapist at four time points during treatment. Results showed a significant predictive value of vulnerable narcissism on the therapeutic alliance, revealing a more beneficial progression for patients with higher vulnerable narcissism. Grandiose narcissism had no predictive value on the therapeutic alliance. The study strengthens the clinical utility of the concept of vulnerable narcissism towards the evaluation of treatment processes in borderline personality disorder.     

Attachment insecurity,mentalization and their relation to symptoms in eating disorder patients

Objective: To investigate the relationships of attachment security and mentalization with core and co-morbid symptoms in eating disorder patients. Method: We compared 51 eating disorder patients at the start of intensive treatment and 20 healthy controls on attachment, mentalization, eating disorder symptoms, depression, anxiety, personality disorders, psycho-neuroticism, autonomy problems and self-injurious behavior, using the Adult Attachment Interview, the SCID-I and II and several questionnaires. Results: Compared with the controls, the eating disorder patients showed a higher prevalence of insecure attachment; eating disorder patients more often than controls received the AAI classification Unresolved for loss or abuse. They also had a lower level of mentalization and more autonomy problems. In the patient group eating disorder symptoms, depression, anxiety, psycho-neuroticism and autonomy problems were neither related to attachment security nor to mentalization; self-injurious behavior was associated with lesser attachment security and lower mentalization; borderline personality disorder was related to lower mentalization. In the control group no relations were found between attachment, mentalization and psychopathologic variables. Discussion: Eating disorder patients’ low level of mentalization suggests the usefulness of Mentalization Based Treatment techniques for eating disorder treatment, especially in case of self-injurious behavior and/or co-morbid borderline personality disorder.     

Dimensional psychopathology of depression: detection of an 'activation' dimension in unipolar depressed outpatients

BACKGROUND: Despite the high prevalence of bipolar spectrum disorders, most instruments currently available for the assessment of depression do not explore symptoms of 'activation' such as anger, irritability, aggressiveness, hostility, and psychomotor activation. METHODS: Two samples of adults with unipolar depression were studied. They had no comorbid DSM-IV disorder, and they were free from antidepressant drugs. The first sample (n = 380) was assessed with the SVARAD, a validated scale for the rapid assessment of the main psychopathological dimensions. The second sample (n = 143) was assessed with the MMPI-2. Factor analysis was performed on SVARAD items and MMPI-2 clinical scales. RESULTS: In both samples, we obtained a three-factor solution with factors interpreted as a depressive dimension, an anxious dimension, and an activation dimension. The latter dimension appeared to be clinically relevant in 20-27% of patients. LIMITATIONS: The presence of a comorbid disorder may have been missed in some cases. Also, some bipolar II patients might have been misdiagnosed as unipolar and included in the study. Further, our findings apply only to a selected psychiatric population, and it should be tested whether they generalize to other settings of care and other countries. CONCLUSIONS: Our results suggest that depressive mixed states are not rare even in patients diagnosed as unipolar, and that some unipolar patients might actually be 'pseudounipolar' and belong to the bipolar spectrum. More in general, our findings suggest that some depressed patients have prominent symptoms of activation that can easily go unnoticed using instruments that do not explore such symptoms. Detecting these symptoms has important treatment implications.
