RESUMO

Background: Most studies on cognitive impairment in bipolar disorder have neglected the role of early stress, despite the high frequency of childhood maltreatment in this clinical group. The aim of this study was to establish a connection between a history of emotional, physical, and sexual abuse in childhood and social cognition (SC) in patients with bipolar disorder type I (BD-I) in euthymia, and to test a possible moderating effect of the single nucleotide polymorphism rs53576 in the oxytocin receptor gene (OXTR). Methods: One hundred and one participants were included in this study. History of child abuse was evaluated using the Childhood Trauma Questionnaire-Short Form. Cognitive functioning was appraised using The Awareness of Social Inference Test (social cognition). The interaction effect between the independent variables OXTR rs53576 (AA/AG and GG) and the absence or presence of any one type of child maltreatment or a combination of types was analyzed using a generalized linear model regression. Results: BD-I patients who had been victims of physical and emotional abuse in childhood and were carriers of the GG genotype at OXTR rs53576 displayed greater SC alterations, specifically in emotion recognition. Discussion: This gene-environment interaction finding suggests a differential susceptibility model of a genetic variants that can be plausibly associated with SC functioning and might help to identify at-risk clinical subgroups within a diagnostic category. Future research aimed at testing the interlevel impact of early stress constitutes an ethical-clinical duty given the high rates of childhood maltreatment reported in BD-I patients.

RESUMO

This document constitutes the second section A of the Third Argentine Consensus on the Management of Bipolar Disorders, focused on synthesizing the most updated evidence on therapeutic approaches for adult patients. The aim of this section (2A) is to provide therapeutic recommendations for managing bipolar disorders in adults. In addition, the scope of this current manuscript outlines recommendations on the use of treatment guidelines, levels of evidence available to support these recommendations, general considerations for the treatment of bipolar disorders, the so-called pseudoresistance and adherence to treatment, general considerations on psychological therapies, as well as long term treatment of bipolar disorders.


Este documento corresponde a la segunda parte del Tercer Consenso Argentino sobre el manejo de los trastornos bipolares, enfocada en sintetizar la evidencia actualizada sobre los abordajes terapéuticos de esta patología en los pacientes adultos. Siguiendo la metodología descripta en la primera parte del Consenso, el panel de expertos realizó una exhaustiva revisión de la bibliografía y, como consecuencia de un posterior debate sobre la información disponible, se generó esta sección A del segundo documento que abarca el tratamiento integral de las personas adultas que padecen este trastorno. Durante la etapa de debate y discusión de estas guías, se decidió incorporar algunos puntos que estimamos serán de gran utilidad para el equipo interdisciplinario encargado del manejo de pacientes con trastornos bipolares.  En tal sentido, en la sección A de la segunda parte de este documento, se podrán encontrar las recomendaciones generales para el uso de las guías de tratamiento, los niveles de evidencia disponibles para sustentar las recomendaciones, las consideraciones generales del tratamiento de los trastornos bipolares, el fenómeno de pseudorresistencia y adherencia al tratamiento, las consideraciones generales sobre el abordaje psicológico, así como el tratamiento a largo plazo de los trastornos bipolares.

RESUMO

The Mood Disorders Questionnaire (MDQ) is a 3-item scale that is frequently used in bipolar disorders (BD) screening and questions the symptoms of BD, its effect on functionality, and the coexistence of symptoms. The aim of this study is to evaluate the prevalence of positive screening of the MDQ among general population and to investigate the associated risk factors.In this cross-sectional study, the sample was randomly selected from household data to represent the city population. A total of 432 participants were asked to fill in MDQ, CAGE (cutting down, annoyance by criticism, guilty feeling, and eye-openers) questionnaire, which consists of four clinical interview questions proven to aid in the diagnosis of alcoholism, and clinical and sociodemographic data form.The Cronbach's alpha value of our current study was 0.813 for MDQ. The prevalence of MDQ positivity was found 7.6%. The estimated prevalence rate of bipolar disorders varied between 0.3 and 13.4% according to different cut-off values. Multivariate logistic regression models showed that the presence of possible alcohol addiction, shift work history, and body mass index (BMI) were statistically significant predictors of MDQ positivity.The prevalence of MDQ positivity found is similar to studies in literature. Keeping in mind that psychometric properties of the MDQ, positive screen results should be cautiously interpreted due to the presence of other risk factors and comorbidities.

RESUMO

The Third Argentine Consensus on the management of bipolar disorders (TB) is an initiative of the Argentine Association of Biological Psychiatry (AAPB). As a reference document, this consensus pursues two main objectives: on the one hand, to summarize and systematize the best available evidence on the comprehensive management of this pathology; on the other, to provide a useful, up-to-date instrument for psychiatrists, multidisciplinary teams dedicated to mental health, and government agencies. During a period of approximately six months of work -that is, from May to October 2022- a committee of experts made up of 18 professionals and representatives of the three most important Psychiatry and Mental Health associations in Argentina (that is, the AAPB, the Argentine Association of Psychiatrists, AAP, and the Association of Argentine Psychiatrists, APSA) have focused on updating the information regarding TB. Finally, this document was prepared as a result of an exhaustive review of the bibliography published to date, which was strategically divided into three parts: the first deals with the generalities of TB; the second deals with the comprehensive treatment of the pathology; finally, the third analyzes TB in the context of special situations.


El Tercer Consenso Argentino sobre el manejo de los Trastornos Bipolares (TB) es una iniciativa de la Asociación Argentina de Psiquiatría Biológica (AAPB). Como documento de referencia, este consenso persigue dos objetivos principales: por un lado, resumir y sistematizar la mejor evidencia disponible sobre el manejo integral de esta patología; por el otro, proporcionar un instrumento útil y actualizado a psiquiatras, a equipos multidisciplinarios abocados a la salud mental y a organismos gubernamentales. Durante un período de aproximadamente seis meses de trabajo -desde mayo a octubre de 2022- un comité de expertos integrado por 18 profesionales y por representantes de las tres asociaciones de Psiquiatría y Salud Mental más importantes de la Argentina: la AAPB, la Asociación Argentina de Psiquiatras, (AAP) y la Asociación de Psiquiatras Argentinos (APSA), se abocaron a actualizar la información respecto de los TB. Finalmente, y como resultado de una exhaustiva revisión de la bibliográfica publicada hasta la actualidad, se confeccionó este documento que fue dividido estratégicamente en tres partes: la primera versa acerca de las generalidades del TB; la segunda aborda el  tratamiento integral de la patología; y, por último, la tercera analiza los TB en el contexto de situaciones especiales.

RESUMO

OBJECTIVE: To evaluate the epidemiological and microbiological aspects of the potential association between bipolar affective disorder (BAPD) and periodontitis. METHODOLOGY: The present case-control study comprised 176 individuals with BAPD and 176 controls. All individuals underwent a complete full-mouth periodontal examination and microbiological sampling. Data on bleeding on probing, probing depth, and clinical attachment level in all present teeth were recorded. Quantification of total bacterial load and Aggregatibacter actinomycetemcomitans, Treponema denticola, and Porphyromonas gingivalis counts were performed through qPCR. Data were analyzed using univariate analysis, Spearman correlation and multivariate logistic regression. RESULTS: The prevalence of periodontitis was 39.7% among controls and 58.5% among individuals with BAPD (OR = 2.13; 95% CI 1.39-3.27). A. actinomycetemcomitans and P. gingivalis counts were significantly higher in individuals with BPAD and periodontitis. The final multivariate logistic regression revealed that periodontitis was strongly associated with the total bacterial load (OR = 1.91; 95% IC = 1.0-1.99; P < 0.001) and the depressive phase of BPAD (OR = 28.94; 95% IC = 4.44-177.27; P < 0.001). CONCLUSION: BAPD was associated with increased risk for periodontitis. Individuals with BPAD presented higher levels of A. actinomycetemcomitans and P. gingivalis, suggesting that periodontitis could be a co-morbidity frequently found in individuals with BAPD.

RESUMO

BACKGROUND: Psychiatric disorders tend to distribute unevenly in women and men with severe obesity. The current research aimed to identify homogeneous clusters of concurrent psychiatric disorders among patients seeking bariatric surgery, by gender. METHODS: We recruited a consecutive sample of 393 candidates with obesity (311 women and 82 men) in a university-based bariatric center. Trained clinicians assessed psychiatric disorders through the Structured Clinical Interview for DSM-IV (SCID). Latent class analysis categorized pre-surgical patients into uniform clusters of co-occurring psychiatric disorders. RESULTS: For both genders, the 3-class psychopathological clustering was the best-fitting solution. Among women, the latent classes were: (1) "oligosymptomatic", wherein 42% of patients showed low probability of psychiatric disorders; (2) "bipolar with comorbidities", in 33%; and (3) "anxiety/depression", in 25%. Among men, (1) "bipolar with comorbidities" was found in 47% of patients; (2) "oligosymptomatic", in 40%; and (3) "anxiety/depression", in 13%. For both genders, the probability of presenting eating disorders was higher in both "bipolar" and "anxiety/depression" classes. Substance use disorders was prominent among "bipolar" men. In comparison with "oligosymptomatic" class, the likelihood of higher BMI was observed among "bipolar" men and poorer work attainment among men with "anxiety/depression". LIMITATION: Participants was cross-sectionally drawn from a single bariatric center. CONCLUSIONS: Pre-surgical men and women with severe obesity were distributed in three comorbidity profiles and revealed analogous psychopathological patterns. The class of "bipolar disorders" most likely presented comorbidity with eating and substance use disorder. This natural clustering of psychiatric disorders among bariatric patients suggests gender-related therapeutic approaches and surgical outcomes.

RESUMO

ABSTRACT Background: Previous studies suggest that inflammatory molecules play an important role in the pathophysiology of Bipolar Disorder (BD). The evidence suggests that BD may present a progressive course. Therefore there are theories that postulate the relationship between progression and stages of the disease with distinct peripheral biomarkers. Objective: The aim of this study was to carry out a systematic review of the literature of studies about the association between peripheral inflammatory markers and clinical variables related with staging in BD patients. Methods: We conducted a systematic review using electronic databases: PubMed, SciELO, LiLACS and PsycINFO. Keywords were divided into inflammatory markers and, BD and staging. Studies involving euthymic BD patients, studies evaluating peripheral biomarkers and studies correlating these with clinical variables related to neuroprogression or stage of BD were included. Results: We present and discuss the methods and findings of ten articles. The inflammatory markers were measured with different techniques and show some contradictories results. The TNF superfamily and inflammatory cytokines may have a relationship with the neuroprogression of the disease. Conclusions: This study suggests that TNF and ILs could play a role in neuroprogression. However, longitudinal studies are needed to clarify the relationship between factors associated with neuroprogression.


RESUMEN Introducción: Estudios previos indican que las moléculas inflamatorias tienen un papel importante en la fisiopatología del trastorno bipolar (TB). La evidencia apunta a que el TB puede presentar un curso progresivo. Por lo tanto, existen teorías que han postulado una relación entre la progresión y los estadios de la enfermedad con diferentes biomarcadores Revisión sistemática periféricos. Objetivo: El objetivo de este estudio es realizar una revisión sistemática de la literatura de los estudios sobre la asociación entre los marcadores inflamatorios periféricos y las variables clínicas relacionadas con la estadificación en los pacientes con TB. Métodos: Se llevó a cabo una revisión sistemática usando las bases de datos electrónicas PubMed, SciELO, LiLACS y PsycINFO. Las palabras clave se dividieron en marcadores inflamatorios y TB y estadificación. Se incluyeron estudios que evaluaron a pacientes con TB en fase de eutimia, estudios que evaluaron biomarcadores periféricos y estudios que correlacionaron dichos marcadores con las variables clínicas relacionadas con la neuroprogresión o estadificación del TB. Resultados: Se presentan y se discuten los métodos y los hallazgos de 10 artículos. Los marcadores inflamatorios se determinaron con diferentes técnicas y mostraron resultados contradictorios. La super familia del factor de necrosis tumoral y las citocinas inflamatorias podrían tener una relación con la neuroprogresión de la enfermedad. Conclusiones: El presente estudio indica que el factor de necrosis tumoral y las intereucinas pueden tener un papel en la neuroprogresión del TB. Sin embargo, se requieren estudios longitudinales con el fin de clarificar la relación entre los factores asociados con la neuro-progresión.

RESUMO

RESUMEN INTRODUCCIÓN: Los pacientes con trastorno afectivo bipolar pueden presentar alteraciones cognoscitivas que en algunos casos tienen un curso progresivo, por lo cual se ha cuestionado si la evolución de esta enfermedad se asocia a demencia, particularmente aquellas pertenecientes al espectro de la degeneración lobar frontotemporal. En este contexto, discriminar si un paciente presenta una demencia secundaria a la enfermedad psiquiátrica de base o si cursa una enfermedad neurodegenerativa además del trastorno afectivo bipolar, es un desafío para el diagnóstico diferencial. OBJETIVO: Comparar los desempeños cognoscitivos en pacientes con trastorno afectivo bipolar, con veinte años o más de evolución de la enfermedad y pacientes con demencia frontotemporal variante conductual. MATERIALES Y MÉTODOS: Estudio exploratorio, descriptivo y transversal en una cohorte seleccionada de casos por método no probabilístico. Los datos se analizan por medio de estadísticos no paramétricos. RESULTADOS: Eespecto al grupo control (N:27), los pacientes con demencia frontotemporal (N:24) presentan desempeños significativamente bajos en memoria verbal, funciones ejecutivas, praxias visoconstruccionales y atención (p <0,01). El grupo de trastorno bipolar (N:17) tiene bajos desempeños en estos procesos, pero no presenta fenómenos patológicos significativos asociados a intrusiones y perseveraciones. Entre los grupos clínicos no se identifican diferencias significativas. CONCLUSIÓN: Aunque los grupos clínicos comparten el compromiso en los procesos cognoscitivos evaluados, los desempeños son más bajos en el grupo de demencia frontotemporal, lo que sugiere que en una enfermedad degenerativa de menor tiempo de evolución y aparición en etapa presenil el déficit cognitivo es mayor que en una enfermedad psiquiátrica crónica.


SUMMARY INTRODUCTION: Patients with Bipolar Disorder may present cognitive alterations that in some cases have a progressive course, whereby it has been questioned if the evolution of this disease is associated with dementia, in particular those that belong to the spectrum of frontotemporal lobar degeneration. Thereby, discriminate if a patient has a dementia secondary to the underlying psychiatric illness or if the patient presents a neurode-generative disease besides the bipolar disorder is a challenge for the differential diagnosis. OBJECTIVE: To compare the cognitive performance in a sample of patients with Bipolar Disorder and twenty years or more of disease progression, and patients with behavioral variant of frontotemporal dementia. MATERIALS AND METHODS: Exploratory, descriptive and transversal study in a cohort of cases selected with a non probabilistic method. Dates are compared through non parametric statistics. RESULTS: Relative to Control group (N:27), Frontotemporal Dementia Patients (N:24) have significantly lower performances in verbal memory, executive functions, visoconstructional praxis and attention tasks (p <0,01). Bipolar Disorder group (N:17) has lower performances in this processes but don't present pathological markers such as intrusions and perseverative responses. There are no significant differences when comparing between clinical groups. CONCLUSION: Although clinical groups share the compromise in most of the cognitive process evaluated, the performances are lower in Frontotemporal dementia group, which suggests that in a degenerative disease of less evolution time and onset in presenile stage, the cognitive deficit is greater than in a chronic psychiatric illness.

RESUMO

This study explores the predictive value of various clinical, neuropsychological, functional, and emotion regulation processes for recovery in Bipolar Disorder. Clinical and demographic information was collected for 27 euthymic or residually depressed BD participants. Seventy one percent of the sample reported some degree of impairment in psychosocial functioning. Both residual depression and problems with emotion regulation were identified as significant predictors of poor psychosocial functioning. In addition, to residual depression, the results of the current study introduce a variable of emotion dysregulation to account for poor psychosocial functioning among BD populations. Improving emotion regulation strategies, in particular, concentration and task accomplishment during negative emotional states could have important consequences for improving overall psychosocial functioning among this population, helping to reduce both the economic burden and high costs to personal wellbeing associated with BD.


Este estudio explora el valor predictivo de los diversos procesos de regulación clínicos, neuropsicológicos, funcionales y emocionales para la recuperación en el Trastorno Bipolar. La información clínica y demográfica se recogió de 27 participantes de TB eutímicos o residualmente deprimidos. Setenta y uno por ciento de la muestra reportó algún grado de deterioro en el funcionamiento psicosocial. Tanto la depresión residual y problemas con la regulación de las emociones fueron identificados como predictores significativos de mal funcionamiento psicosocial. Además de la depresión residual, los resultados del presente estudio introducen una variable de disregulación emocional para dar cuenta del pobre funcionamiento psicosocial en las poblaciones de TB. La mejora de las estrategias de regulación emocional, en particular, la concentración y la realización de tareas durante los estados emocionales negativos podrían tener consecuencias importantes para mejorar el funcionamiento psicosocial global en esta población ayudando a reducir tanto la carga económica y los altos costos para el bienestar personal asociado con TB.

RESUMO

The aim of this study is to present an updated view of the writings on the endophenotype model for bipolar disorder using analytical methodologies. A review and analysis of networks was performed through descriptors and keywords that characterize the composition of the endophenotype model as a model of health. Information was collected from between 1992 and 2014, and the main thematic areas covered in the articles were identified. We discuss the results and question their cohesion, emphasizing the need to strengthen and identify the points of connection between etiological factors and characteristics that make up the model of endophenotypes for bipolar disorder.


El objetivo de este trabajo es presentar una visión actualizada de los escritos del modelo endofenotipo para el trastorno bipolar, el uso de las metodologías analíticas. Se realizó una revisión de este tipo de literatura y un análisis de las redes a través de descriptores y palabras clave que caracterizan la composición del modelo endofenotipo como modelo de salud. El momento de la recolección de la información se produjo entre los años 1992-2014, la identificación de las principales áreas temáticas incluidas en los artículos. Se discuten los resultados para la consolidación del modelo de endofenotipos, cuestionando la cohesión y haciendo hincapié en la necesidad de fortalecer e identificar los puntos de conexión entre los factores etiológicos y características que conforman el modelo de endofenotipos para el trastorno bipolar.


O objetivo do presente estudo é o de apresentar uma visão atualizada sobre a produção bibliográfica do modelo de endofenótipo para o transtorno bipolar, recorrendo às metodologias analíticas. Foi realizada para tal uma revisão da literatura e uma análise de redes por meio de descritores e palavras-chaves, que caracterizam a composição do modelo de endofenótipo como um modelo de saúde. O período de recolha das informações ocorreu entre os anos de 1992-2014, identificando nos principais artigos os âmbitos temáticos abordados. Discutem-se os resultados obtidos para a consolidação do modelo de endofenótipos, questionando a coesão e ressaltando a necessidade de reforçar e identificar os pontos de ligação entre os fatores etiológicos e as características que compõe o modelo de endofenótipos para o transtorno bipolar.

RESUMO

BACKGROUND: Anxiety commonly co-occurs with bipolar disorders (BDs), but the significance of such "co-morbidity" remains to be clarified and its optimal treatment adequately defined. METHODS: We reviewed epidemiological, clinical, and treatment studies of the co-occurrence of BD and anxiety disorder through electronic searching of Pubmed/MEDLINE and EMBASE databases. RESULTS: Nearly half of BD patients meet diagnostic criteria for an anxiety disorder at some time, and anxiety is associated with poor treatment responses, substance abuse, and disability. Reported rates of specific anxiety disorders with BD rank: panic ≥ phobias ≥ generalized anxiety ≥ posttraumatic stress ≥ obsessive-compulsive disorders. Their prevalence appears to be greater among women than men, but similar in types I and II BD. Anxiety may be more likely in depressive phases of BD, but relationships of anxiety phenomena to particular phases of BD, and their temporal distributions require clarification. Adequate treatment trials for anxiety syndromes in BD patients remain rare, and the impact on anxiety of treatments aimed at mood stabilization is not clear. Benzodiazepines are sometimes given empirically; antidepressants are employed cautiously to limit risks of mood switching and emotional destabilization; lamotrigine, valproate, and second-generation antipsychotics may be useful and relatively safe. CONCLUSIONS: Anxiety symptoms and syndromes co-occur commonly in patients with BD, but "co-morbid" phenomena may be part of the BD phenotype rather than separate illnesses.

RESUMO

This paper describes the findings of a systematic literature review aimed at providing an overview of the lifetime prevalence of bipolar disorder and bipolar spectrum disorders in population-based studies. Databases MEDLINE, ProQuest, Psychnet, and Web of Science were browsed for papers published in English between 1999 and May 2012 using the following search string: bipolar disorders OR bipolar spectrum disorders AND prevalence OR cross-sectional OR epidemiology AND population-based OR non-clinical OR community based. The search yielded a total of 434 papers, but only those published in peer-reviewed journals and with samples aged ≥ 18 years were included, resulting in a final sample of 18 papers. Results revealed rather heterogeneous findings concerning the prevalence of bipolar disorders and bipolar spectrum disorders. Lifetime prevalence of bipolar disorder ranged from 0.1 to 7.5%, whereas lifetime prevalence of bipolar spectrum disorders ranged from 2.4 to 15.1%. Differences in the rates of bipolar disorder and bipolar spectrum disorders may be related to the consideration of subthreshold criteria upon diagnosis. Differences in the prevalence of different subtypes of the disorder are discussed in light of diagnostic criteria and instruments applied


O presente artigo descreve os achados de uma revisão sistemática da literatura cujo objetivo foi oferecer uma visão geral sobre a prevalência de transtorno bipolar e transtornos do espectro bipolar em estudos populacionais. A busca foi realizada nas bases de dados MEDLINE, ProQuest, Psychnet e Web of Science, com foco em estudos publicados em inglês entre 1999 e maio de 2012, utilizando-se a seguinte estratégia de busca: bipolar disorders OR bipolar spectrum disorders AND prevalence OR cross-sectional OR epidemiology AND population-based OR non-clinical OR community based. Foram encontrados 434 artigos, mas apenas publicações em revistas científicas com processo de revisão por pares (peer review) e envolvendo participantes com 18 anos ou mais foram incluídos, gerando uma amostra final de 18 estudos. Encontraram-se dados bastante heterogêneos sobre a prevalência do transtorno bipolar e de transtornos do espectro bipolar. A taxa de prevalência do transtorno bipolar ao longo da vida variou entre 0,1 e 7,5%, enquanto a taxa dos transtornos do espectro bipolar variou entre 2,4 e 15,1%. As diferenças entre as prevalências de transtorno bipolar e de transtornos do espectro bipolar parecem estar relacionadas à consideração de formas subliminares no momento do diagnóstico. As diferenças de prevalência dos diferentes subtipos do transtorno são discutidas em relação aos critérios diagnósticos e instrumentos utilizados

RESUMO

Background: Large scale neuropsychological studies of patients with bipolar disorder have reported verbal memory and executive function deficits that persist during remission. A recent analysis by Thompson et al. (2009) indicated that verbal memory deficits could be entirely explained by the statistical variance attributed to primary executive function deficits. This study tests the hypothesis that verbal memory deficits in bipolar patients are largely the result of executive difficulties by direct comparison of verbal neuropsychological tests primarily differing in their executive load as well as examining potential interactions with medication status. Methods: 33 Bipolar I patients not taking medication, 40 Bipolar I patients taking medication, and 28 healthy controls were compared on measures of IQ, verbal fluency, category fluency, verbal recall, and category prompted recall. Results: After controlling for IQ, performance on tasks that involved additional executive involvement was significantly worse. Medication had a small but reliable effect on cognitive performance. Conclusions: The results provide support to the hypothesis that the most significant source of cognitive impairment in bipolar disorder stems from executive impairment and that verbal memory deficits may arise as a result of this, rather than from primary impairment to core verbal memory mechanisms.


Introducción: Los estudios neuropsicológicos a gran escala de pacientes con trastorno bipolar han reportado déficits en la memoria verbal y en la función ejecutiva que persisten durante la remisión. Un análisis reciente realizado por Thompson et al. indicó que los déficits en la memoria verbal podían explicarse enteramente por la varianza estadística atribuida a los déficits en la función ejecutiva primaria. Este estudio demuestra la hipótesis de que los déficits en la memoria verbal de pacientes bipolares son mayormente el resultado de las dificultades ejecutivas mediante una comparación directa de pruebas neuropsicológicas verbales, que difieren principalmente en su carga ejecutiva, como también mediante la examinación las interacciones potenciales con el estado de la medicación. Métodos: Se compararon 33 pacientes con trastorno bipolar I que no estaban tomando medicamentos con 28 controles saludables respecto a sus medidas de coeficiente intelectual (CI), fluidez verbal, fluidez de categorías, memoria verbal y memoria alentada por categorías. Resultados: Después de realizar controles relacionados con el CI, el desempeño que requería un mayor involucramiento ejecutivo era significativamente peor. Los medicamentos tenían un efecto pequeño pero confiable sobre el desempeño cognitivo. Conclusiones: Los resultados soportan la hipótesis de que la fuente más significativa de trastornos cognitivos en el trastorno bipolar es el trastorno ejecutivo y que pueden surgir déficits en la memoria verbal como resultado de este, y no de un trastorno primario de los mecanismos centrales de la memoria verbal.

RESUMO

Introduction: Insight represents a variable quality in subjects with bipolar disorders not only during the presence of acute episodes, but also during euthymic periods. It has been observed that the cognitive alterations found in the acute phase of mood disorders persist during the remission of symptoms. Therefore, variables, insight and cognitive alterations could be linked. The objective of this study is to establish the relationship between the cognitive functions and insight in euthymic bipolar I subjects. Method: In order to establish the alteration of the cognitive functions, we applied the Neuropsychological Battery Luria-Nebraska (BNLN) to a group of 25 euthymic bipolar I subjects. The same subjects were tested with the SUMD test (Scale to Assess Unawareness of Mental Disorder) and the relationship between both psychometric instruments was studied. Results: 76 per cent of the subjects showed signifi cant cognitive alterations. The most altered functions corresponded to intellectual processes, memory processes, arithmetic skills and receptive language. We found that the subject with less cognitive alterations represented a better insight then those with a higher cognitive defi cit. Conclusions: The results give evidence about the presence of cognitive alterations in euthymic bipolar patients. Those with a lesser cognitive deficit have a better capacity for insight or a higher awareness of sickness, according to the parameters of SUMD.


Introducción: El insight representa una cualidad variable en sujetos portadores de cuadros bipolares no sólo durante la presencia de los episodios agudos, sino también durante eutimia. Se ha observado que las alteraciones cognitivas encontradas en las fases agudas de los trastornos anímicos persistirían también en la remisión de los síntomas. Por lo tanto, ambas variables, insight y alteraciones cognitivas pueden estar vinculadas entre sí. El objetivo del presente estudio es establecer las relaciones de las funciones cognitivas y el insight en sujetos bipolares I eutímicos. Método: Para establecer la alteración de las funciones cognitivas, se aplicó la Batería Neuropsicológica Luria-Nebraska (BNLN) a un grupo de 25 bipolares tipo I eutímicos. A los mismos sujetos se les aplicó el test SUMD (Scale to Assess Unawareness of Mental Disorder) y se relacionaron ambos instrumentos psicométricos. Resultados: El 76 por ciento de los sujetos mostró alteraciones cognitivas significativas. Las funciones más alteradas correspondieron a los Procesos Intelectuales, Procesos Mnésicos, Destrezas Aritméticas y Lenguaje Receptivo. Se encontró que los sujetos con menores alteraciones cognitivas presentaban un mejor insight que aquellos con un mayor déficit cognitivo. Conclusiones: Los resultados aportan evidencias acerca de la presencia de alteraciones cognitivas en pacientes bipolares eutímicos. Aquellos con un menor déficit cognitivo poseen una mejor capacidad de insight o mayor conciencia de enfermedad, según los parámetros del SUMD.

RESUMO

OBJECTIVE: Bipolar spectrum disorders (BSDs) are prevalent and frequently unrecognized and undertreated. This report describes the development and validation of the Brazilian version of the bipolar spectrum diagnostic scale (B-BSDS), a screening instrument for bipolar disorders, in an adult psychiatric population. METHOD: 114 consecutive patients attending an outpatient psychiatric clinic completed the B-BSDS. A research psychiatrist, blind to the B-BSDS scores, interviewed patients by means of a modified version of the mood module of the Structured Clinical Interview for DSM-IV ("gold standard"). Subthreshold bipolar disorders were defined as recurrent hypomania without a major depressive episode or with fewer symptoms than those required for threshold hypomania. RESULTS: The internal consistency of the B-BSDS evaluated with Cronbach's alpha coefficient was 0.89 (95 percent CI; 0.86-0.91). On the basis of the modified SCID, 70 patients (61.4 percent) of the sample received a diagnosis of BSDs. A B-BSDS screening score of 16 or more items yielded: sensitivity of 0.79 (95 percent CI; 0.72-0.85), specificity of 0.77 (95 percent CI; 0.70-0.83), a positive predictive value of 0.85 (95 percent CI; 0.78-0.91) and a negative predictive value of 0.70 (95 percent CI; 0.63-0.75). CONCLUSION: The present data demonstrate that the B-BSDS is a valid instrument for the screening of BSDs.


OBJETIVO: Transtornos do espectro bipolar (TEB) são prevalentes e comumente subdiagnosticados e subtratados. O presente trabalho descreve o desenvolvimento e a validação da versão brasileira da escala diagnóstica do espectro bipolar (B-EDEB), um instrumento de rastreio para transtornos bipolares, em uma população psiquiátrica adulta. MÉTODO: 114 pacientes consecutivos de um ambulatório psiquiátrico completaram a versão brasileira da B-EDEB. Um psiquiatra pesquisador, cego para os escores do B-EDEB, entrevistou os participantes por meio de uma versão modificada do módulo de transtornos do humor da entrevista clínica estruturada para o DSM-IV ("padrão-ouro"). RESULTADOS: A consistência interna da B-EDEB, avaliada mediante o coeficiente alfa de Cronbach, foi de 0,89 (IC 95 por cento; 0,86-0,91). De acordo com o padrão-ouro, 70 (61,4 por cento) participantes tiveram diagnóstico de TEB. Um escore da B-EDEB de 16 ou mais itens apresentou sensibilidade de 0,79 (IC 95 por cento; 0,72-0,85), especificidade de 0,77 (IC 95 por cento; 0,70-0,83), valor preditivo positivo de 0,85 (IC 95 por cento; 0,78-0,91) e valor preditivo negativo de 0,70 (IC 95 por cento; 0,63-0,75). CONCLUSÃO: Os resultados do presente estudo demonstram que a B-EDEB é um instrumento válido para o rastreio de TEB.

RESUMO

Introduction: Numerous investigations have reported that cognitive alterations found during active episodes in mood disorders will persist in euthymic states and could be associated to the social and occupational dysfunctions found in an important rate of bipolar patients. Therefore, it is necessary to study the characteristics of these cognitive disturbances in order to establish therapeutic proceedings that will include this factor. The objective of the present study is the evaluation of the cognitive functions in euthymic bipolar patients. It was hypothesized that the cognitive functions of the bipolar patients would be impaired. Methods: To establish the permanence or the impairment of the cognitive functions, the Luria-Nebraska Neuropsychological Battery (LNNB) was applied to a group of 25 euthymic bipolar type I patients. Results: 76 percent of the patients tested showed significant cognitive impairment. Receptive language, arithmetic skills, mnemic and intellectual processes were affected most. Conclussion: The results show evidence that cognitive dysfunctions found in mood disorders are not exclusive of active episodes, and could persist during remission. These findings were congruent with previous investigations that utilized different psychometrical tests.


Introducción: Numerosas investigaciones han observado que las alteraciones cognitivas encontradas en las fases agudas de los trastornos anímicos persistirían aun en remisión y podrían asociarse a las disfunciones sociales y ocupacionales encontradas en sujetos con trastornos anímicos. Por lo tanto, resulta necesario estudiar las características de las alteraciones de las funciones cognitivas en orden de establecer procedimientos terapéuticos que aborden este factor. El objetivo del presente estudio es la evaluación de las funciones cognitivas en sujetos bipolares eutímicos. Se planteó la hipótesis de que las funciones cognitivas de los sujetos evaluados se encontrarían alteradas. Método: Para establecer la alteración o permanencia de las funciones cognitivas, se aplicó la Bateria Neuropsicológica Luria-Nebraska (BNLN) a un grupo de 25 bipolares tipo I eutímicos. Resultados: El 76 por ciento de los sujetos mostró alteraciones cognitivas significativas. Las funciones más alteradas correspondieron a los Procesos Intelectuales, Procesos Mnésicos, Destrezas Aritméticas y Lenguaje Receptivo. Conclusiones: Los resultados aportan evidencias de alteraciones cognitivas en pacientes bipolares eutímicos. Esto sería congruente con investigaciones anteriores realizadas con pruebas psicométricas distintas.
