Immunization stress-related responses presenting as psychogenic non-epileptic seizures following HPV vaccination in Rio Branco, Brazil.

IMPORTANCE: The absence of a positive diagnosis of psychogenic non-epileptic seizures (PNES) in immunization stress-related response (ISRR) clusters may have not only a direct impact on affected patients' health but may also reduce compliance to national vaccination programs. It is therefore crucial to develop efficient diagnostic tools and a feasible proposal for proper communication and treatment of ISRR. PURPOSE: To explore the psychogenic nature of patients' convulsive seizures in a suspected outbreak of an ISRR cluster following human papillomavirus vaccination in Rio Branco, Brazil. METHODS: Twelve patients with convulsive seizures were submitted to prolonged intensive video-electroencephalography monitoring, brain magnetic resonance imaging, cerebrospinal fluid diagnostic testing, laboratory subsidiary examinations, and complete neurological and psychiatric evaluations. RESULTS: Ten patients received the positive diagnosis of PNES, and two patients received the diagnosis of idiopathic generalized epilepsy. No biological association was found between the HPV vaccine and the clinical problems presented by the patients. CONCLUSIONS: Prolonged VEEG monitoring can contribute significantly to the positive diagnosis of PNES in ISRR clusters and to avoid hesitancy to vaccinate.

Comorbid epilepsy and psychogenic non-epileptic seizures: how well do patients and caregivers distinguish between the two.

PURPOSE: To determine whether patients with comorbid epilepsy and psychogenic nonepileptic seizure (PNES) and their caregivers can distinguish between these two events at least one year after initial diagnosis, and to investigate factors associated with correct identification. METHODS: Adult patients with at least a one year diagnosis of both epilepsy and PNES, confirmed through video-electroencephalography (VEEG), were selected. Patients and a caregiver of their choice were interviewed and shown videos containing the patients' epileptic and PNES events. Variables associated with correct identification of events by patients and their caregivers were evaluated. RESULTS: Twenty-four patients participated in the study. Mean time between VEEG diagnosis and enrollment in the study was 26.8 months (±12.4). Six of patients correctly distinguished between the events shown. Factors associated with correct identification were the absence of intellectual disability, unremitted PNES, and a degree of preserved awareness during the PNES event. Twelve caregivers correctly distinguished between the events shown. Factors associated with correct identification among caregivers were the presentation of only one epileptic seizure type in the patient, and the participation of the caregiver during VEEG monitoring and communication of PNES diagnosis to the patient. CONCLUSION: A significant proportion of patients with epilepsy and PNES and their caregivers seem to be unable to discriminate between these events a year after diagnosis. These findings have implications for both clinical follow-up and research involving this population. Future research should further investigate methods that would allow patients and their caregivers to better distinguish between these two events.

[Psychogenic non-epileptic seizures: history and critique of a concept]. / Crise não epiléptica psicogênica: história e crítica de um conceito.

This discussion of the evolution of psychiatric knowledge concerning psychogenic non-epileptic seizures (PNES) sheds light on the epistemological assumptions underlying the concept and on its practical implications as well. PNES are defined as repeated seizures or attacks which can be mistaken for epilepsy because of the similar behavioral changes displayed, but which differ in that they are not the result of abnormal electrical activity in the brain and may be psychogenic in origin. The article investigates the historical development of the concept of PNES over the past forty years. The concepts of psychiatric comorbidity, abuse, and dissociation enter the discussion owing to their roles in the checkered development of the concept of PNES.

Crise não epiléptica psicogênica: história e crítica de um conceito / Psychogenic non-epileptic seizures: history and critique of a concept

Discute o desenvolvimento do conhecimento psiquiátrico sobre a crise não epiléptica psicogênica (CNEP), buscando iluminar os pressupostos epistemológicos do conceito e suas implicações práticas. Em sua definição atual, crises ou ataques recorrentes são manifestações comportamentais semelhantes às da epilepsia, mas que dela diferem por não serem consequentes de descargas elétricas cerebrais anormais, podendo ter origem psicogênica. Em direção inversa da metafísica, investiga-se a emergência histórica do conceito de CNEP nos últimos quarenta anos. Conceitos de comorbidade psiquiátrica, abuso e dissociação foram discutidos devido a sua participação na trajetória conceitual de CNEP.

Epilepsy in patients with psychogenic non-epileptic seizures.

The aim of this study was to evaluate the frequency of epilepsy in patients who presented psychogenic non-epileptic seizures (PNES). The evaluation was carried out during intensive VEEG monitoring in a diagnostic center for epilepsy in a university hospital. The difficulties involved in reaching this diagnosis are discussed. Ninety-eight patients underwent intensive and prolonged video-electroencephalographic (VEEG) monitoring; out of these, a total of 28 patients presented PNES during monitoring. Epilepsy was defined as present when the patient presented epileptic seizures during VEEG monitoring or when, although not presenting epileptic seizures during monitoring, the patient presented unequivocal interictal epileptiform discharges. The frequency of epilepsy in patients with PNES was 50% (14 patients). Our findings suggest that the frequency of epilepsy in patients with PNES is much higher than that of previous studies, and point out the need, at least in some cases, for prolonging the evaluation of patients with PNES who have clinical histories indicating epilepsy.

O objetivo deste estudo foi avaliar a frequência de epilepsia em pacientes que apresentaram crises não epilépticas psicogênicas (CNEP). Isto foi realizado durante monitoração intensiva por video-EEG num centro diagnóstico de epilepsia em um hospital universitário. As dificuldades envolvidas para se chegar a este diagnóstico são discutidas. Noventa e oito pacientes foram submetidos a monitoração intensiva por video-EEG; 28 destes pacientes apresentaram CNEP durante a monitoração. Epilepsia foi considerada presente quando o paciente apresentou crises epilépticas durante a avaliação pelo video-EEG ou quando, apesar da não ocorrência de crises epilépticas durante a avaliação, descargas epilépticas interictais inequívocas estavam presentes. A frequência de epilepsia em pacientes com CNEP foi 50 por cento (14 pacientes). Nossos achados sugerem que a frequência de epilepsia em pacientes com CNEP é maior do que a apresentada em estudos anteriores e apontam para a necessidade de, ao menos em alguns casos, prolongar a avaliação de pacientes com CNEP, mas com história clínica sugestiva de epilepsia.

Evaluating patients with suspected nonepileptic psychogenic seizures.

The authors evaluate 26 patients with suspected psychogenic non-epileptic seizures (PNES) who were referred to prolonged intensive video EEG (VEEG) in an epilepsy diagnostic center at the University of São Paulo, Brazil. Following the investigative protocol, 50% of the patients received a diagnosis of PNES, 15.4% of epilepsy, and 34.6% of associated PNES and epilepsy. In all patients in our series, PNES were the pseudoneurological presentations of dissociative or conversion symptoms in patients presenting the following mental disorders: conversion disorder, somatization or undifferentiated somatoform disorder, dissociative disorder not otherwise specified, and posttraumatic stress disorder. Psychiatric comorbidities, mostly depressive disorders, were frequent.

Psychiatric diagnoses of patients with psychogenic non-epileptic seizures.

OBJECTIVE: Our purpose was to present and discuss the psychiatric diagnoses of patients who presented psychogenic non-epileptic seizures (PNES) during video-electroencephalographic monitoring (VEEG). METHODS: Out of 98 patients, a total of 28 patients presented PNES during the diagnostic procedure. In those cases in which the PNES that occurred during VEEG were validated by clinical history (clinical validation), and by showing the recorded event on video to an observer close to the patient (observer validation), was defined psychogenic non-epileptic seizure disorder (PNESD). Psychiatric diagnoses were made according to DSM-IV. RESULTS: In 27, psychogenic non-epileptic seizures disorder was diagnosed. Fourteen patients presented only with psychogenic non-epileptic seizure disorder, 13 with both psychogenic non-epileptic seizures disorder and epilepsy, and one patient with epilepsy only. Psychiatric diagnoses were: 17 (63%) patients with conversion disorder, five (19%) with somatization disorder, two (7%) with dissociative disorder NOS, two (7%) with post-traumatic stress disorder and one (4%) with undifferentiated somatoform disorder. CONCLUSIONS: Dissociative-conversion non-epileptic seizures are the most frequent finding, representing the pseudoneurological manifestation of mental disorders that have these symptoms as a common feature. Provisionally, they may be defined as dissociative-conversion non-epileptic seizure disorders.

Resultados preliminares de um programa de tratamento de crises não-epilépticas psicogênicas / Preliminary results of the treatment program of psychogenic nonepileptic seizures

Apesar dos avanços no diagnóstico das crises não epilépticas psicogênicas (CNEP), até o presente momento não há tratamentos que sejam padronizados e eficientes. O presente estudo examinou a freqüência de crises e as condições de trabalho e acadêmicas em um grupo de pacientes portadores de CNEP antes e depois de completarem um programa de oito semanas específico, desenvolvido no PROJEPSI (Projeto de Epilepsia e Psiquiatria) do Instituto de Psiquiatria do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, com os objetivos de redução da freqüência de crises e de danos associados ao diagnóstico de CNEP. Ao final do programa de tratamento, 15 pacientes (62,5 por cento) apresentavam-se em remissão e 19 (79,2 por cento) apresentaram melhora do desempenho profissional ou acadêmico. O presente estudo fornece evidências da eficácia do programa de atendimento dos pacientes portadores de CNEP proposto pelo PROJEPSI. O número significativo de pacientes que apresentam remissão e redução do número de crises após a comunicação terapêutica do diagnóstico, do tratamento das comorbidades psiquiátricas e da terapia para redução de danos e crises (TRDC) sugere que o conhecimento da doença por parte dos pacientes, familiares e amigos convidados é essencial ao tratamento.

In spite of the growing interest in psychogenic nonepileptic seizures (PNES), this diagnosis clearly lacks both standard protocols and efficient treatment. We analyzed seizure frequency, as well as, academic and working performances in a group of PNES patients, both prior and following a specific eight-week program developed at PROJEPSI (Epilepsy and Psychiatry Project) - Institute of Psychiatry, Hospital de Clinicas, School of Medicine, University of Sao Paulo. The program targeted seizure reduction and decrease in losses associated to PNES. Fifteen patients (62.5 percent) entered prolonged remission and 19 (79.2 percent) improved academic and professional performances. Our study shows evidence supporting the efficacy of the NES protocol proposed by PROJEPSI. The number of patients presenting with either remission or significant decrease on their seizures following the diagnosis presentation, psychiatric comorbidity treatment and specific therapy aiming to damage and crisis suggests that the knowledge of this condition by patients, family members and friends is key to successful treatment.

Transtornos mentais associados à epilepsia / Mental disorders associated with epilepsia

Epilepsia é o mais freqüente transtorno neurológico sério, atingindo 50 milhões de pessoas no mundo, 40 milhões delas em países em desenvolvimento. Embora seja um problema predominantemente tratável, nestes países a maioria dos pacientes permanece sem tratamento. Provavelmente uma das principais causas para isto seja o estigma que atinge as pessoas com epilepsia. Tal fato se agrava ainda mais quando à epilepsia se associam transtornos mentais, que ocorrem com prevalência aumentada. Os pacientes com epilepsia e transtornos mentais sofrem o que se chama de "duplo estigma", que freqüentemente os deixa sem tratamento. É provável, particularmente em países em desenvolvimento, que psiquiatras se defrontem com pacientes com epilepsia nos diferentes locais de atendimento. Os autores revisam diferentes aspectos dos principais transtornos mentais associados à epilepsia.

Volumetric evidence of a left laterality effect in epileptic psychosis.

We investigated anatomic alterations and lateralization effect in the mesial temporal lobe structures (amygdala and hippocampus) in epileptic psychosis MRI volumetric measurements. Patients with epileptic psychosis and normal controls were studied. Left hippocampus values were significantly smaller for patients (P<0.001). Hippocampal ratio was significantly greater for patients (P<0.01). Group (patients x normal) was the only factor explaining the statistically significant variation of left hippocampus and hippocampal ratio (P<0.001 and P<0.05). Twenty patients had hippocampal atrophy (4 on the right side, 15 on the left side, and 1 bilateral) associated with mesial temporal sclerosis. These results confirm the existence of anatomic alterations and a left laterality effect in the mesial temporal lobe structures of patients with epileptic psychosis.

Clinical aspects of epileptic psychosis in Brazil.

We investigated a series of patients with epileptic psychosis in Brazil and compared our findings with those of other authors. We evaluated 38 outpatients with epileptic psychosis with a semistructured clinical interview, Annett inventory for hand dominance, international classifications for seizures and syndromes, and DSM-IV for psychosis diagnoses. We studied course and outcome for epilepsy and psychosis. Gender distribution was approximately even. Epilepsy and psychiatric disorders among relatives and early CNS insults in personal histories were frequent findings. Mean age of epilepsy onset was 9.3 years. Epilepsy started before psychosis in all cases, and evolved to clinical refractoriness. There was a predominance of temporal lobe epilepsy. Mean age of psychosis onset was 27.4 years, after a mean duration of epilepsy of 18.1 years, with predominance of schizophrenic presentations with interictal onset, frequent psychiatric admissions, suicide attempts, and postpsychosis functional decline. Tumors or lesions of an embryologic nature were uncommon, but mesial temporal sclerosis was frequent.

Diagnóstico e tratamento de epilepsia e crises pseudoepilépticas psicogênicas associadas: relato de caso / Diagnosis and treatment of associated epilepsy and psychogenic pseudoepileptic seizures: case report

Relatamos o caso de uma paciente de 26 anos em que é evidenciada a importância médica do diagnóstico diferencial entre epilepsia e crises pseudo-epilépticas psicogênicas (CPEP) e do seu tratamento. A paciente, uma professora desempregada, com crises desde os 13 anos, foi encaminhada ao PROJEPSI para diagnóstico e tratamento de CPEP. Seu diagnóstico inicial foi de epilepsia parcial sintomática por lesäo tumoral cística em regiäo occipto-temporal esquerda, associada a CPEP. Submetida a craniotomia occipital com ressecçäo de processo expansivo em regiäo de istmo do cíngulo, evoluiu com persistência das CPEP. Submetida a tratamento psicológico integrado envolvendo técnicas de condicionamento operante, manejo de ansiedade, sugestäo e orientaçäo familiar, houve remissäo completa das CPEP após 4 meses de tratamento. O caso apresentado demonstra a necessidade de múltiplos procedimentos diagnósticos e terapêuticos e a participaçäo de equipe multidisciplinar especializada.
