OBJECTIVES: To report the prevalence and factors associated with the use of benzodiazepines in the general population and those with a mental health condition in the metropolitan area of São Paulo, Brazil. METHODS: 5,037 individuals from the Sao Paulo Megacity Mental Health Survey data were interviewed using the Composite International Diagnostic Interview, designed to generate DSM-IV diagnoses. Additionally, participants were asked if they had taken any medication in the previous 12 months for the treatment of any mental health condition. RESULTS: The prevalence of benzodiazepine use ranged from 3.6% in the general population to 7.8% among subjects with a mental health condition. Benzodiazepine use was more prevalent in subjects that had been diagnosed with a mood disorder as opposed to an anxiety disorder (14.7% vs. 8.1%, respectively). Subjects that had been diagnosed with a panic disorder (33.7%) or bipolar I/II (23.3%) reported the highest use. Individuals aged ≥50 years (11.1%), those with two or more disorders (11.2%), those with moderate or severe disorders (10%), and those that used psychiatric services (29.8%) also reported higher use. CONCLUSION: These findings give an overview of the use of benzodiazepines in the general population, which will be useful in the public health domain. Benzodiazepine use was higher in those with a mental health condition, with people that had a mood disorder being the most vulnerable. Furthermore, females and the elderly had high benzodiazepine use, so careful management in these groups is required.

Objective: Exposure and response prevention (ERP) is effective to treat obsessive-compulsive disorder (OCD), but the lack of tolerance to the aversion nature of exposure techniques results in a high drop-out rate. There have been reports of a generic stress endurance effect of serotonin (5-HT) in the central nervous system (CNS) which might be explained by suppression of defensive fixed action patterns. Previous studies have proposed that higher baseline 5-HT concentration and slow decrease in concentration during drug treatment of OCD were predictors of good clinical response to 5-HT reuptake inhibitors. The objective of this study was to investigate whether pre-treatment platelet rich plasma (PRP) 5-HT concentration is associated with latency of treatment response and final response to an ERP protocol for obsessive-compulsive disorder (OCD). Methods: Thirty adult and treatment-free OCD patients were included in an 8-week, 16-session ERP protocol. 5-HT concentration was determined at baseline and after treatment. Patients with a reduction ≥30% on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at the end of ERP were defined as responders. Results: A positive correlation between baseline 5-HT concentration and reduction of symptoms on the Y-BOCS was observed after 4 weeks. Baseline 5-HT concentration was not correlated with clinical response after 8 weeks of ERP, possibly due to the similar though delayed clinical response of patients with lower (compared to those with higher) baseline 5-HT concentration. Patients with higher 5-HT baseline concentration also showed more improvement in depressive symptoms with treatment. Conclusion: The present results partially support the hypothesis of a stress endurance effect of 5-HT in OCD patients. According to the literature, fast onset responders possibly have more or larger 5-HT containing neurons, higher endogenous 5-HT synthesis or lower monoamine oxidase activity; all these hypotheses remain to be investigated.

Objectives: 1) To identify whether patients with panic disorder in general and those with the respiratory subtype in particular actively avoid exercise; 2) to investigate physiological differences in cardiopulmonary function parameters in patients with panic disorder in general, patients with the respiratory subtype of panic disorder, and healthy controls upon exercise challenge. Methods: Patients with panic disorder were classified as having either the respiratory or the non-respiratory subtype. Both groups were compared to controls in terms of exercise avoidance patterns and performance on cardiopulmonary exercise testing. Results: Patients with panic disorder exhibited higher exercise avoidance scores and worse performance on cardiopulmonary exercise testing as compared with controls. No differences were found between patients with the respiratory and non-respiratory subtypes. Conclusions: Exercise avoidance is present in panic disorder and is associated with poorer performance on cardiopulmonary exercise testing. These findings are not limited to patients with the respiratory subtype of the disorder.

OBJECTIVES: Approximately 40-60% of obsessive-compulsive disorder patients are nonresponsive to serotonin reuptake inhibitors. Genetic markers associated with treatment response remain largely unknown. We aimed (1) to investigate a possible association of serotonergic polymorphisms in obsessive-compulsive disorder patients and therapeutic response to selective serotonin reuptake inhibitors and (2) to examine the relationship between these polymorphisms and endocrine response to intravenous citalopram challenge in responders and non-responders to serotonin reuptake inhibitors and in healthy volunteers. METHODS: Patients with obsessive-compulsive disorder were classified as either responders or non-responders after long-term treatment with serotonin reuptake inhibitors, and both groups were compared with a control group of healthy volunteers. The investigated genetic markers were the G861C polymorphism of the serotonin receptor 1Dβ gene and the T102C and C516T polymorphisms of the serotonin receptor subtype 2A gene. RESULTS: The T allele of the serotonin receptor subtype 2A T102C polymorphism was more frequent among obsessive-compulsive disorder patients (responders and non-responders) than in the controls (p<0.01). The CC genotype of the serotonin receptor subtype 2A C516T polymorphism was more frequent among the non-responders than in the responders (p<0.01). The CC genotype of the serotonin receptor subtype 1Dβ G681C polymorphism was associated with higher cortisol and prolactin responses to citalopram (p<0.01 and p<0.001, respectively) and with a higher platelet-rich plasma serotonin concentration among the controls (p<0.05). However, this pattern was not observed in the non-responders with the same CC genotype after chronic treatment with serotonin reuptake inhibitors. This CC homozygosity was not observed in the responders.

CONTEXTO: Os sintomas de transtornos de personalidade (Eixo II) comumente encontrados em pacientes com fobia social se sobrepõem com os sintomas que descrevem o transtorno pelo Eixo I. OBJETIVO: O presente estudo teve por objetivo avaliar traços de personalidade em pacientes com diagnóstico de fobia social. MÉTODO: Cento e oito sujeitos com idade entre 18 e 65 anos foram avaliados pelo Inventário de Temperamento e Caráter de Cloninger. RESULTADO: Os pacientes com fobia social diferiram dos dados normativos nos seguintes traços de personalidade: Busca à Novidade, Fuga de Danos, Persistência, Autodirecionamento e Autotranscendência. CONCLUSÃO: Esses achados apontam para uma sobreposição entre a descrição dos traços de personalidade citados por Cloninger e a descrição dos sintomas de fobia social do DSM-IV, Eixo I.

BACKGROUND: The symptoms of personality disorders (Axis II) commonly found in social phobia patients overlap highly with the symptoms that typify the Axis I disorder and are thus linked to diagnostic process in symptomatic patients. OBJECTIVE: The aim of the present study was to evaluate personality traits of social phobia patients. METHOD: One hundred and eight subjects were selected, from 18 to 65 years of age, who fulfilled the criteria of social phobia. The Cloninger's Temperament and Character Inventory (TCI) was applied. RESULTS: Social phobia patients differed in normalized data in the following personality traits: Novelty Seeking, Harm Avoidance, Persistence, Self Directedness, and Self-Transcendence. DISCUSSION: These findings point to a high overlap between Cloninger's description of the observed predominant personality traits and DSM-IV Axis I symptoms description for social phobia.

OBJETIVO: O padrão comportamental da fobia é adquirido com base no condicionamento clássico e mecanismos operantes de aprendizagem. Este artigo faz uma revisão dos principais determinantes da etiologia da fobia de deglutição e descreve o tratamento da terapia comportamental em uma paciente adulta. MÉTODO: Foram usadas psicoeducação, análise funcional e gradativa exposição a estímulos aversivos no tratamento da paciente, depois de uma extensiva avaliação psiquiátrica e psicológica. Níveis de ingesta e ansiedade foram medidos ao longo de todo o tratamento e no follow-up. RESULTADOS: Para demonstrar a completa remissão dos sintomas, após sete sessões de exposição a diferentes grupos de alimentos foi usado um delineamento de linha de base de avaliações múltiplas. CONCLUSÃO: Terapia de exposição e psicoeducação foram componentes que contribuíram de modo crítico para a obtenção de resultados positivos ao tratamento.

OBJECTIVE: A phobic behavior pattern is learned by classical and operant conditioning mechanisms. The present article reviews the main determinants of choking phobia etiology and describes the behavior therapy of an adult patient. METHOD: Psychoeducation, functional analysis, and graded exposure to aversive stimuli were used to treat the patient, after extensive psychiatric and psychological assessment. Ingesta and anxiety levels were measured along treatment and at follow-up. RESULTS: A multiple assessment baseline design was used to demonstrate the complete remission of symptoms after seven sessions, each of them exposing the patient to a different group of foods. CONCLUSION: Psychoeducation and exposure were critical components of a successful choking phobia treatment.

OBJETIVO: Comorbidade com transtornos de personalidade tem sido extensamente descrita no transtorno obsessivo-compulsivo. Aproximadamente 40% dos pacientes com transtorno obsessivo-compulsivo não respondem a tratamentos de primeira linha. Não obstante, não existem estudos comparando diretamente traços de personalidade entre pacientes responsivos e refratários ao tratamento do transtorno obsessivo-compulsivo. Este estudo investiga diferenças nos traços da personalidade baseados no Inventário de Temperamento e Caráter de Cloninger (TCI) entre dois grupos de pacientes com transtorno obsessivo-compulsivo classificados segundo desfecho terapêutico: responsivos e refratários. MÉTODO: Quarenta e cinco pacientes refratários e 44 responsivos foram selecionados. Os indivíduos foram considerados responsivos se, após tratamento com terapêutica convencional, apresentaram diminuição de ao menos 40% no escore inicial da Yale-Brown Obsessive Compulsive Scale, foram classificados como "melhor" ou "muito melhor" na Clinical Global Impressions; e mantiveram melhora por pelo menos um ano. Os refratários eram os pacientes que não atingiram redução de ao menos 25% na Yale-Brown Obsessive Compulsive Scale e tiveram a melhoria menor que "mínima" na Clinical Global Impressions após o tratamento com ao menos três inibidores seletivos da recaptura de serotonina, incluindo clomipramina, e ao menos 20 horas da terapia cognitiva-comportamental. Os traços da personalidade foram avaliados através do Temperament and Character Inventory. RESULTADOS: Refratários pontuaram menos em autodirecionamento e tenderam a pontuar mais em persistência. CONCLUSÃO: Este estudo sugere que os traços de personalidade, especialmente autodirecionamento, estão associados com a resposta pobre do tratamento em pacientes com transtorno obsessivo-compulsivo.

OBJECTIVE: Comorbidity with personality disorders in obsessive-compulsive patients has been widely reported. About 40% of obsessive-compulsive patients do not respond to first line treatments. Nevertheless, there are no direct comparisons of personality traits between treatment-responsive and non-responsive patients. This study investigates differences in personality traits based on Cloninger's Temperament and Character Inventory scores between two groups of obsessive-compulsive patients classified according to treatment outcome: responders and non-responders. METHOD: Forty-four responsive and forty-five non-responsive obsessive-compulsive patients were selected. Subjects were considered treatment-responsive (responder group) if, after having received treatment with any conventional therapy, they had presented at least a 40% decrease in the initial Yale-Brown Obsessive Compulsive Scale score, had rated "better" or "much better" on the Clinical Global Impressions scale; and had maintained improvement for at least one year. Non-responders were patients who did not achieve at least a 25% reduction in Yale-Brown Obsessive Compulsive Scale scores and had less than minimal improvement on the Clinical Global Impressions scale after having received treatment with at least three selective serotonin reuptake inhibitors (including clomipramine), and at least 20 hours of cognitive behavioral therapy. Personality traits were assessed using Temperament and Character Inventory. RESULTS: Non-responders scored lower in self-directedness and showed a trend to score higher in persistence than responders did. CONCLUSION: This study suggests that personality traits, especially self-directedness, are associated with poor treatment response in obsessive-compulsive patients.

Os ataques de pânico são representados por um período distinto no qual há o início súbito de intensa apreensão, temor ou terror, freqüentemente associados com sentimentos de catástrofe iminente, diagnosticado em aproximadamente 10% da população. O Transtorno de Pânico é um transtorno de ansiedade que se caracteriza pela recorrência de ataques de pânico: crises súbitas de mal-estar e sensação de perigo ou morte iminente, acompanhadas de diversos sintomas físicos e cognitivos. Os indivíduos com Transtorno de Pânico apresentam, caracteristicamente, preocupações acerca das implicações ou conseqüências dos ataques de pânico. É uma condição clínica complexa que envolve diferentes modalidades ou conglomerados de sintomas. Assim, o foco nas sensações físicas erroneamente interpretadas no transtorno de pânico e na hipocondria centraliza-se basicamente nas manifestações autonômicas, como taquicardia e dispnéia. Há poucos estudos sobre atividade física e transtorno de pânico. O principal objetivo do estudo visa identificar com diferentes descrições se há uma população "nuclear" com sintomas predominantemente respiratórios apresentando esquiva de atividade física e a influência do exercício nesta população.

Panic attacks are represented by distinct periods in which there is a sudden beginning of internal apprehension, fear or terror, frequently associated with feelings of imminent catastrophe, diagnosed in approximately 10% of the population. The panic disorder is an anxiety crisis that is characterized by the recurrence of panic attacks: sudden crises of uneasiness and sensation of danger or imminent death, followed by diverse physical and cognitive symptoms. Individuals with panic disorder are characteristically concerned about panic attacks implications or consequences. It is a complex clinical condition that involves different modalities or myriad of symptoms. Thus, the focus on the physical sensations misinterpreted in panic disorder and hypochondria, is basically centered in autonomic manifestations, such as tachycardia and dyspnea. There are scarce studies on physical activity and panic disorder. The main purpose of the study is to identify with different descriptions whether there is a 'main' population with symptoms predominantly respiratory presenting avoidance of physical activity and exercise influence on this population.

INTRODUÇÃO: A enxaqueca apresenta elevada comorbidade com os transtornos de humor e de ansiedade e extremo impacto no grau de incapacidade e qualidade de vida do indivíduo afetado, mas pouco se sabe sobre a qualidade de vida dos pacientes com enxaqueca crônica e o impacto das comorbidades psiquiátricas. MÉTODO: Cinquenta pacientes com diagnóstico de enxaqueca crônica (Sociedade Internacional de Cefaléias, 2004) foram diagnosticados quanto à presença de transtornos mentais, através da entrevista estruturada SCID-I/P e do questionário de qualidade de vida SF-36. Pacientes foram divididos nos seguintes grupos: enxaqueca crônica com transtornos de ansiedade, transtorno de ansiedade generalizada, transtornos de ansiedade com pelo menos um episódio depressivo maior, com episódio depressivo maior, comparados a pacientes sem comorbidade psiquiátrica. RESULTADOS: Constatou-se qualidade de vida significativamente inferior nos oito domínios da SF-36, nos pacientes com enxaqueca crônica associada a comorbidade psiquiátrica tais como transtornos de ansiedade, transtorno de ansiedade generalizada, transtornos de ansiedade com pelo menos um episódio depressivo maior, assim como nos pacientes apenas com episódio depressivo maior, comparados a pacientes com enxaqueca crônica sem comorbidade psiquiátrica (p<0,05). Somente no domínio Estado Geral de Saúde do SF-36, a qualidade de vida não foi significativamente inferior em todos os grupos de pacientes com enxaqueca crônica associada a comorbidade psiquiátrica. Nos domínios do SF-36 relacionados aos aspectos físicos, a qualidade de vida não foi significativamente inferior somente nos transtornos de ansiedade. CONCLUSÃO: A comorbidade da enxaqueca crônica e transtornos mentais é fator associado à piora da qualidade de vida dos pacientes e deve ser ativamente pesquisada nesta população.

INTRODUCTION: Chronic migraine is a common, debilitating condition affecting quality of life and social functioning with significant impact. Migraine is highly comorbid with anxiety and mood disorders, but little is known about psychiatric comorbidities impact in the migraine patient quality of life. METHOD: Fifty patients with chronic migraine diagnosed according to the International Headache Society (2004) were interviewed and met diagnostic criteria for mental disorders, according to the structured interview SCID-I/P and were evaluated by the SF-36 Health Survey questionnaire. Patients were divided in the following groups: chronic migraine with both mood and anxiety disorders, with only anxiety disorders, with generalized anxiety disorder, with only a mood disorder, and without psychopathology. The scores in the group without psychopathology were compared with the other groups. All eight domains of the SF-36 scale were compared in those groups. RESULTS: Significantly lower (p<0.05) quality of life was found on all eight SF-36 domains for CM psychiatric comorbidity patients compared to no-co morbidity patients. On the SF-36 General Health domain alone, quality of life was not significantly lower for all four CM psychiatric comorbidity groups. On the SF-36 Physical Aspects domain alone, quality of life was not significantly lower only for the Anxiety Disorders group. CONCLUSION: Chronic migraine comorbidity with mental disorder is a significant factor affecting patients' quality of life.

INTRODUÇÃO: As comorbidades psiquiátricas das enxaquecas crônicas são bem conhecidas. As fobias, transtorno ansioso mais comum, são mais prevalentes entre enxaquecosos do que entre não enxaquecosos. O perfil clínico de fobias em uma população enxaquecosa nunca foi estudado. MÉTODO: Estudamos aspectos psiquiátricos de uma população de 56 pacientes com enxaqueca crônica. RESULTADOS: Usando o SCID I/P para o DSM-IV, critérios diagnósticos para ao menos algum transtorno psiquiátrico durante a vida foram preenchidos por 87,5% de nossa amostra, 75% para ao menos um transtorno ansioso e 60,7% para condições fóbicas em algum momento de suas vidas. Os escores de ansiedade e humor foram maiores entre os fóbicos e o número de fobias teve correlação positiva com o grau de ansiedade e depressão. CONCLUSÃO: Fobias são comuns na enxaqueca crônica e seu reconhecimento poderia influenciar seu manejo e melhorar seu prognóstico.

BACKGROUND: Comorbidity of chronic migraine (CM) with psychiatric disorders, mostly anxiety and mood disorders, is a well-recognized phenomenon. Phobias are one of the most common anxiety disorders in the general population. Phobias are more common in migraineurs than non-migraineurs. The clinical profile of phobias in CM has never been studied. METHOD: We investigated the psychiatric profile in 56 patients with CM using the SCID I/P interview. RESULTS: Lifetime criteria for at least one mental disorder was found in 87.5% of the sample; 75% met criteria for at least one lifetime anxiety disorder and 60.7% of our sample fulfilled DSM-IV criteria for lifetime phobic avoidant disorders. Mood and anxiety scores were higher in phobic patients than in non-phobic CM controls. Number of phobias correlated with higher levels of anxiety and depression. CONCLUSION: Phobias are common in CM. Its recognition may influence its management. Early treatment may lead to better prognosis.

INTRODUÇÃO: A migrânea crônica (MC) é uma doença comum, que afeta 2,4% da população geral. A depressão é uma das comorbidades mais frequentes em enxaqueca. MÉTODO: Setenta pacientes diagnosticados com migrânea crônica foram estudados. Todos os pacientes preencheram o Inventário de Depressão Beck.(BDI). A gravidade da depressão foi dividida em nenhuma ou leve, mínima, moderada, e grave. RESULTADOS: O BDI variou de 4 a 55, média 21 ± 10,7. A depressão moderada ou grave esteve presente em 58,7% dos pacientes. Algum grau de depressão foi observado em 85,8% dos pacientes. Os escores de depressão correlacionaram-se com a intensidade da dor. A depressão grave foi mais freqüente em paciente com comorbidade com fibromialgia e fadiga. CONCLUSÃO: O BDI é um instrumento de fácil avaliação da depressão em MC. A identificação do risco de suicídio é necessária nestes pacientes. Fibromialgia e fadiga são fatores de risco para depressão grave.

INTRODUCTION: Chronic migraine (CM) is a common medical condition affecting 2.4% of the general population. Depression is one of the most frequent comorbid disorders in CM. METHOD: Seventy patients diagnosed with chronic migraine were studied. All patients evaluated filled out the Beck Depression Inventory (BDI). Depression severity was divided into none or minimal depression, mild, moderate, and severe. RESULTS: BDI ranged from 4 to 55, mean 21 ± 10.7. Moderate or severe depression, were present in 58.7% of the patients . Some degree of depression appeared in 85.8% of patients. The BDI scores correlated with pain intensity (p = 0.02). Severe depression was more frequent in patients with comorbid fibromyalgia and in patients reporting fatigue. CONCLUSION: The BDI is an easy tool to access depression in CM patients. Suicide risk assessment is needed in CM patients. Patients with fibromyalgia and fatigue are at even higher risk for severe depression.

OBJETIVO: Investigar se o uso do cloridato de betanecol é uma alternativa útil no manejo clínco da disfunção orgásmica induzida pela clomipramina, relatada por até 96 % dos usuários do sexo masculino. MÉTODOS: Foram estudados 12 pacientes do sexo masculino em remissão completa de transtorno de pânico porém com queixas de disfunção orgásmica grave secundária ao uso da clomipramina. Os pacientes foram aleatoriamente distribuídos ao tratamento com cloridrato de betanecol (20 mg quando necessário) ou placebo em um estudo duplo cego "crossover" de dois períodos. RESULTADOS: Foi observado um benefício claro no período de uso da droga ativa. Não foram observados efeito placebo ou "carry-over" nos pacientes inicialmete alocados ao medicamento ativo. CONCLUSÕES: Os resultados deste estudo sugerem que o cloridato de betanecol, usado em doses únicas, 45 minutos antes da relação sexual, pode ser útil em pacientes do sexo masculino apresentado disfunção orgásmica secundária ao uso da clomipramina.

PURPOSE: To investigate whether bethanecol chloride may be an alternative for the clinical management of clomipramine-induced orgasmic dysfunction, reported to occur in up to 96% of male users. METHODS: In this study, 12 fully remitted panic disorder patients, complaining of severe clomipramine-induced ejaculatory delay, were randomly assigned to either bethanecol chloride tablets (20 mg, as needed) or placebo in a randomized, double-blind, placebo-controlled, two-period crossover study. A visual analog scale was used to assess severity of the orgasmic dysfunction. RESULTS: A clear improvement was observed in the active treatment period. No placebo or carry-over effects were observed. CONCLUSION: These findings suggest that bethanecol chloride given 45 minutes before sexual intercourse may be useful for clomipramine-induced orgasmic dysfunction in males.

Os relatos da literatura e a experiência clínica tem demonstrado que pacientes com transtorno de pânico são capazes de identificar estressores que precederam o primeiro ataque de pânico. O objetivo deste trabalho é investigar a relação entre eventos vitais, estratégias de enfrentamento a estresse e transtorno de pânico. MÉTODO: Foram comparados 43 pacientes com transtorno de pânico com 29 sujeitos controle no que diz respeito a ocorrência e impacto dos eventos vitais estressores no ano que precedeu o primeiro ataque de pânico. Para tanto utilizou-se a Escala de Reajustamento Social e London Life Event and Difficulty Schedule. As estratégias de enfrentamento foram avaliadas pelo Inventário de Estratégias de Coping. RESULTADOS: O número de eventos vitais estressores relatados por ambos os grupos era estatísticamente equivalente. Os sujeitos do grupo experimental mas não os do grupo controle relataram perda de suporte social como a mais importante classe de eventos vitais. As estratégias de enfrentamento utilizadas em resposta aos eventos estressores foram pouco efetivas e desadaptadas, diferentemente do grupo controle. CONCLUSÕES: O presente estudo indica que não é o número de eventos vitais que determina a relevância de sua ocorrência para os pacientes de pânico, mas as estratégias de enfrentamento utilizadas, bem como o significado adverso atribuído aos eventos e o impacto desses eventos em suas vidas.

Research literature and clinical experience shows that panic patients are often able to identify stressors that preceded the onset of their first attacks. In this study we investigated the relation between life events, coping skills, and panic disorder. METHODS: Forty-tree panic patients were compared with 29 control subjects regarding the occurrence and the impact of stressful life events in a 1-year period preceding the onset of panic attacks using the Social Readjustment Rating Scale and London Life Event and Difficulty Schedule. Coping skills were measured using the Ways of Coping Questionnaire. RESULTS: No differences were observed between panic patients and controls regarding the number of reported stressful life events in the previous year. Panic patients compared to controls reported loss of social support as the most meaningful class of events significantly more often. In response to stressful situations, panic patients more often used coping skills judged as ineffective. CONCLUSIONS: The present study suggests that the type of life event and the coping skills used in response to them, more than the occurrence of stressful events itself, may be associated with the onset of panic disorder.

A estimulação magnética transcraniana de repetição (EMTr) vem sendo amplamente investigada como ferramenta terapêutica em transtornos psiquiátricos, especialmente a depressão. Neste trabalho, compilamos as informações provenientes de estudos que investigaram as aplicações da EMTr no tratamento dos transtornos de ansiedade: transtorno do pânico (TP), transtorno de estresse pós-taumático (TEPT), transtorno de ansiedade generalizada (TAG) e especialmente o transtorno obsessivo compulsivo (TOC). Três estudos foram publicados abordando o tratamento do TOC, sendo que utilizaram metodologias e parâmetros de aplicação extremamente diversos, dificultando a obtenção de informações conclusivas sobre a efetividade deste tratamento. Quatro estudos publicados sobre TEPT e EMTr também apresentam dados conflitantes e pouco comparáveis, mas destaca-se publicação recente com desenho duplo-cego e resultados positivos. Quanto ao TP e o TAG, apenas pequenas investigações iniciais foram realizadas. Conclusão: Apesar dos estudos citados, não há dados conclusivos sobre a eficácia terapêutica da EMTr nos transtornos de ansiedade. Isto se dá especialmente devido aos estudos com amostras pequenas e desenho aberto. Portanto, devem ser realizados estudos mais aprofundados para que possamos obter estas respostas.

Repetitive transcranial magnetic stimulation (rTMS) have been widely studied as a therapeutic method in psychiatric disorders, specially in major depression. In this paper, we have compiled the information from studies concerning the use of rTMS as a therapeutic tool for anxiety disorders: panic disorder (PD), post-traumattic stress disorder (PTSD), generalized anxiety disorder (GAD) and mainly obsessive-compulsive disorder (OCD).Three studies have been published concerning treatment of OCD with rTMS, but they are very different in their methods and in the application parameters and location, making it difficult to draw any conclusion about the efficacy of rTMS in this cases. Four studies published on PTSD also showed very ambiguous and hardly comparable data, but a recent double-blind study with positive results is discussed. Very few inicial investigations are available concerning PD and GAD. Conclusion: Although many studies are mentioned, thete is no conclusive data about the therapeutic efficacy of rTMS in anxiety disorders. It is mainly due to a large number of open-labelled studies with small sample sizes. Therefore, studies with a deeper approach are needed to provide this answers.
