Prevalence of ictal injuries in functional (psychogenic nonepileptic) seizures: A systematic review and meta-analysis.

OBJECTIVE: Ictal injuries have long been considered typical signs of epileptic seizures. However, studies have shown that patients with functional seizures (FS)-also named psychogenic nonepileptic seizures-can also present these signs, misleading physicians and delaying a correct diagnosis. This systematic review aimed to assess the prevalence of injuries from FS. METHODS: A literature search was performed in PubMed, Embase, LILACS (Latin American and Caribbean Health Sciences Literature), Scopus, Web of Science, PsycINFO, Google Scholar, OpenGrey, and ProQuest. Observational studies were included. The risk of bias was assessed using the Joanna Briggs Institute (JBI) checklist for studies reporting prevalence data. RStudio was used for meta-analyses. Cumulative evidence was evaluated according to Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. RESULTS: From the 2607 identified records, 41 studies were included in the qualitative synthesis, and 28 were included in meta-analyses. A meta-analysis of 13 studies, including 1673 individuals, resulted in an overall lifetime prevalence of injuries due to FS per person of 25% (95% confidence interval [CI] = 19%-32%, I2 = 88%). Considering a limited period (video-electroencephalographic [VEEG] monitoring days), a meta-analysis of 13 studies, including 848 individuals, resulted in an injury prevalence due to FS per person of .7% (95% CI = 0%-3%, I2 = 73%). Also, a meta-analysis of eight studies, including 1000 individuals, resulted in a prevalence of injuries per FS of .1% (95% CI = 0%-.98%, I2 = 49%). The certainty in cumulative evidence assessed by GRADE was rated "very low" for lifetime prevalence of injuries per person, "low" for prevalence per person during VEEG monitoring, and "moderate" for prevalence per number of FS. SIGNIFICANCE: Overall pooled lifetime prevalence of injuries due to FS per person was 25%. In comparison, the prevalence of injuries per person during VEEG monitoring and per functional seizure was .7% and .1%, respectively. [Correction added on 07 October 2023, after first online publication: In the preceding sentence, 'consecutively' was corrected to 'respectively'.] The evidence of the occurrence of injuries due to FS breaks the paradigm that epileptic seizures can cause injuries but FS cannot.

Faux Pas Recognition Test: transcultural adaptation and evaluation of its psychometric properties in Brazil.

Introduction: Many neuropsychiatric and neurodegenerative disorders produce Theory of Mind impairment. We aimed to implement a Brazilian Portuguese version of the Faux Pas Recognition Test (FPRT) and evaluate its psychometric properties.Methods: We first completed an English-Brazilian Portuguese translation and adaptation to obtain an FPRT Brazilian Portuguese version. We performed a multicentric study with 153 healthy participants (68.6% women), mean age of 38.8 years (SD = 14.6) and 12.9 years of schooling (SD = 4.5). Linear regression analysis was performed to evaluate the association of social class, age, schooling, and FPRT scores. The psychometric analyses comprised item analysis, exploratory factor analysis, reliability, and validity analysis.Results: Normative data in a Brazilian population is presented. A positive correlation of scores with years of schooling, social class, and an inverse relation with age was found. The exploratory factorial analysis found a two-component structure, one component, consisting of questions 1 through 6 (Eigenvalue 5.325) and another component, consisting of questions 7 and 8 (Eigenvalue 1.09). Cronbach's alpha of the 20 stories was .72. All control stories had a poor discriminative index.Conclusion: The FPRT Brazilian Portuguese version demonstrated good internal consistency and, psychometric properties and is adequate for use even in lower educational contexts in Brazil.

Esclerose Mesial Temporal: Prevalência em um ambulatório de referência no Hospital Universitário Professor Polydoro Ernani de São Thiago / Mesial Temporal Sclerosis: Prevalence study in a reference outpatient clinic at Hospital Universitário Professor Polydoro Ernani de São Thiago

A epilepsia é uma doença heterogênea com alto impacto global, principalmente dentre aquelas pessoas com pobre controle clínico. Um de seus espectros é a esclerose mesial temporal, um tipo de epilepsia do lobo temporal cuja etiologia é estrutural e se caracteriza por lesões hipocampais uni ou bilaterais. Esta é a causa mais comum de epilepsia do lobo temporal farmacorresistente. Em cerca de 2/3 dos casos, ela é relacionada a um nível insatisfatório de controle clínico mediante medidas farmacológicas. Contudo, existe uma opção terapêutica adequada para o controle de crises nesta patologia, a intervenção cirúrgica. O presente trabalho trata-se de um estudo descritivo observacional transversal o qual visa analisar a prevalência da esclerose mesial temporal e o perfil epidemiológico dos pacientes acompanhados no ambulatório de referência do Hospital Universitário Professor Polydoro Ernani de São Thiago. Mais de 80% destes possuem epilepsia resistente a medicamentos, porém apenas 22% deles foram submetidos à cirurgia. Além disso, os pacientes apresentaram um convívio médio de 34 anos com a doença. Diante disso, propõe-se uma discussão acerca dos motivos da baixa disponibilidade da terapia cirúrgica para esclerose mesial temporal e o impacto dessa condição em nossa realidade.

Epilepsy is a heterogeneous disease with a high impact, mainly among those patients who have poorly controlled seizures. The most common cause of pharmacoresistant epilepsy is mesial temporal lobe epilepsy associated with uni or bilateral hippocampal sclerosis. Approximately 60% of the cases, it is related to unsatisfactory clinical control through pharmacological measuresis refractory to pharmacological treatment. However, there is an effective and safe therapeutic option, although still heavily underutilized, which is surgical therapy. This is a cross-sectional observational study, which aimed to analyze the prevalence of mesial temporal sclerosis and the epidemiological profile of these patients at the outpatient clinic of Hospital Universitário Professor Polydoro Ernani de São Thiago. Among the participants, more than 80% of those were considered drug resistant epilepsy, however, only 22% of them were submitted to surgery. Additionally, the patients had an average of 34 year of disease duration. In light of this, we discussed the main reasons for this surgical gap for mesial temporal sclerosis, and the impact of this persistent underutilization of surgical therapy in Brazil.
