Crisis no epilépticas psicógenas: Semiología en una cohorte de pacientes de una unidad de epilepsia de referencia nacional en Lima, Perú / Non-epileptic psychogenic seizures: semiology in a patient's cohort from a national reference epilepsy unit in Lima, Peru

RESUMEN Objetivo : Describir la semiología de crisis no epilépticas psicógenas (CNEP) en pacientes diagnosticados mediante videoelectroencefalograma (VEEG) en un centro nacional de epilepsia. Material y métodos : Estudio observacional, descriptivo y retrospectivo que incluyó a pacientes mayores de 14 años, ingresados a monitoreo de telemetría en el Hospital Nacional Edgardo Rebagliati Martins en Lima, Perú, entre el 1 de enero de 2017 y el 31 de diciembre de 2022, y definitivamente diagnosticados con CNEP mediante VEEG. Resultados : La mayoría de los 26 pacientes (20 mujeres y 6 varones) presentó pérdida de postura con caída (92 %), así como una instauración gradual (88 %) y cursaron con algún grado de alteración de conciencia o responsividad durante el evento (73 %). Los signos motores más prevalentes fueron movimientos asincrónicos de tronco y/o extremidades (73 %), fluctuación en la actividad motora (73 %), temblor global o en extremidades (54 %) y cierre palpebral forzado (50 %). Las manifestaciones clínicas no motoras fueron, en su mayoría, síntomas subjetivos (34 %). La mayoría (73 %) presentó CNEP motoras (73 %), en comparación con otras manifestaciones no motoras (12 %) y mixtas (15 %). Conclusiones : Los eventos clínicos descritos fueron de larga duración e instauración gradual y mostraron alteraciones de conciencia/responsividad. Los signos clínicos motores más frecuentes fueron movimientos asincrónicos de tronco y/o extremidades, fluctuación motora, temblor y cierre palpebral forzado. Los hallazgos no motores fueron, en su mayoría, síntomas subjetivos. La mayoría de los pacientes presentaron CNEP motoras.

ABSTRACT Objective : To describe the semiology of Psychogenic Non-Epileptic Seizures (PNES) in patients diagnosed by video-electroencephalogram (VEEG) in a national epilepsy center. Methods : An observational, descriptive, and retrospective study of patients older than 14 years, admitted for telemetry monitoring at the Epilepsy Unit of the National Hospital Edgardo Rebagliati Martins in Lima, Peru, between January 1st, 2017, and December 31, 2022. A definitive diagnosis of PNES was reached through VEEG. Results : Twenty of 26 studied patients were female and 6 male. Most patients experienced loss of posture with falls (92%), gradual onset (88%), some degree of altered consciousness or responsiveness during the event (73%). The most prevalent motor signs included asynchronous movements of the trunk and/or extremities (73%), fluctuation in motor activity (73%), global or limb tremors (54%), and forced eyelid closure (50%). Non-motor signs were predominantly subjective symptoms (34%). Most of the patients presented motor PNES (73%) compared to non-motor (12%) and mixed (15%). Conclusions : The described clinical events had a prolonged duration, gradual onset, and altered levels of consciousness/responsiveness. The most frequent clinical motor signs were asynchronous movements of the trunk and/or extremities, motor fluctuation, tremors, and forced eyelid closure. Non-motor findings were, primarily, subjective symptoms. Most of the patients presented motor PNES.

Calidad de vida en pacientes con epilepsia y crisis no epilépticas psicógenas: una revisión sistemática / Quality of life in patients with epilepsy and psychogenic nonepileptic seizures: a systematic review

Resumen Se han revisado artículos que estudiaron la calidad de vida en las personas con crisis no epilépticas psicógenas (CNEP) y crisis epilépticas. Se siguió la guía PRISMA y, previo a la búsqueda, se realizó un protocolo publicado en PROSPERO. Se incluyeron estudios aleatorizados y no aleatorizados, de tipo cuantitativo o mixtos, de corte transversal o longitudinal, escritos en lengua inglesa o española publicados hasta el año 2020, y cuyos participantes fueran mayores de 16 años. Luego de filtrar los resultados según los criterios de selección, se incluyeron 11 artículos y una tesis doctoral cuyos años de publicación datan de 1998 a 2020. En su mayoría, se informaba que las personas con CNEP tenían menor calidad de vida, asociadas a presencia de psicopatología, así como también a la toma de medicación antiepiléptica, factores sociodemográficos y relacionados con las crisis (frecuencia, severidad y duración de enfermedad), funcionamiento familiar, trauma y somatización.

Abstract Psychogenic non epileptic seizures (PNES) are disruptive changes in behaviour, thought, or emotion that resemble an epileptic seizure, but without paroxysmal neuronal discharge detectable by electroencephalography (EEG), and are not caused by another medical condition. On the other hand, epileptic seizures (ES) are defined as clinical events that reflect the presence of hypersynchronous discharges of neurons located in the cerebral cortex, which have the particularity of starting and ending abruptly. The diagnosis of epilepsy is made when an epileptic seizure was experienced and there is a risk of having another. The objective of this paper is to present the results of a systematic review of articles that have studied quality of life in people with PNES and ES. This review has been performed following the PRISMA guide (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Prior to the beginning of the search, a protocol was carried out and it is published for consultation in the International prospective register of systematic reviews (PROSPERO). The review includes randomized and non-randomized, quantitative or mixed, cross-sectional or longitudinal studies, published in English or Spanish until 2020. In addition, participants had to be over 16 years old. PNES diagnosis must have been confirmed by video-electroencephalography (VEEG) or a similar procedure-which is considered the gold standard for the diagnosis of PNES.

Pseudoseizures with urinary incontinence in a child with Neuromyelitis optica: a rare association

Background: Paroxysmal non epileptic events or pseudoseizures are common seizure mimics in children. But occasionally PNES events can present or coexist along with organic neurological disorders complicating the clinical scenario posing great challenges for diagnostic and therapeutic implications. Unusual symptomatology in PNES like frothing, tongue bite or urinary incontinence can be seen in PNES. Here, we present a rare case of pseudoseizures with urinary incontinence in a child with Neuromyelitis optica which posed a challenge for diagnosis and proper management with a favourable clinical outcome. A 14 years old girl who was known diagnosed case of Neuromyelitis optica on treatment with oral steroids presented with a history of repeated attacks of involuntary movements affecting all four limbs preceded by a feeling of fear and pain and these events were associated with urinary incontinence. Electroencephalogram and magnetic resonance imaging were performed on the patient. Ictal video EEG confirmed the diagnosis of pseudoseizures. Neuropsychological evaluation was performed which revealed multiple psychological stressors. Repeated counseling sessions and psychotherapy provided significant improvement in the form of remission of pseudoseizures.

Modelos conceptuales y explicativos sobre las crisis no epilépticas psicógenas (CNEP) / Conceptual and explanatory models of Psychogenic Non-Epileptic Seizures (PNES)

Las Crisis No Epilépticas Psicógenas (CNEP) son episodios similares a las crisis epilépticas, pero a diferencia de éstas, no son causadas por la actividad eléctrica anómala del cerebro. Se diagnostican una vez descartadas otras causas fisiopatológicas. El objetivo de este artículo es presentar la conceptualización actual de este fenómeno. Para ello, en primer lugar realizaremos una historización del fenómeno, relacionándolo con la categoría de histeria; segundo lugar, describiremos las clasificaciones propuestas por las distintas ediciones del Manual Diagnóstico y Estadístico de los trastornos mentales, destacando su última versión (DSM-V); finalmente, introduciremos las corrientes actuales que explican este fenómeno, las cuales toman el rol de la disociación como categoría central que explica tanto el diagnóstico así como los objetivos de tratamiento para las CNEP. La categoría disociación es la clave para entender la dirección en la que se está avanzando en psicopatalogía, la búsqueda de los procesos psicológicos específicos subyacentes para entender el mecanismo que lleva a producir tanto las CNEP como otros cuadros de psicopatológicos.

Psychogenic Non Epileptic Crises (CNEP) have been a challenge to diagnostic and explanation for the mental health field. They are diagnosed after discard out other pathophysiological causes of the crisis. They are similar to epileptic seizures, but unlike these, they are not caused by electrical activity in the brain. In order to present the current conceptualization of this phenomenon, we propose in first place to describe its historical development, second, the current classification of the Diagnostic and Statistical Manual (DSM-V), third, to introduce the present currents that explain this phenomenon by taking the role of dissociation as a central category that explains the diagnosis and the treatment objectives for the CNEP. The dissociation category is the key to understand the direction in which progress is being made in psychopathology, the search for the specific underlying psychological processes to understand the mechanism that leads to producing both the CNEP and other psychopathological frames.

Psychogenic non-epileptic seizures and psychoanalytical treatment: results / Crises não epilépticas psicogênicas e tratamento psicanalítico: resultados.

Background: the occurrence of psychogenic non-epileptic seizures (PNES) is estimated to be between 2 to 33 cases in every 100,000 inhabitants. The number of patients with PNES reaches 19% of those treated as epileptics. Patients with PNES are treated as if they had intractable epilepsy, with unsatisfactory results even after medication treatment is used to its maximum. The aim of this study is to present the effects of individual psychoanalytical treatment in patients with PNES, assessing its impact in the evolution of the clinical picture and its association with sex, time of disease, social, psychological and professional harm, as well as going through with treatment. Methods: The case base was composed of 37 patients with PNES. The diagnosis was reached with video-EEG monitoring. Psychoanalytical treatment was carried out through 12 months of weekly sessions timed for around 50-minutes each, in a total of 48 individual sessions. Results: This study found a high rate of success in the treatment of PNES patients. 29.7% (n=11) of patients had cessation or cure of symptoms and 51.4% (n=19) had a decrease in the number of episodes. There is an association between cessation or decrease in the number of episodes and sex (p<0.01), religion (p<0.01) and concluding treatment (p<0.01). Conclusion: Individual psychoanalytical treatment applied to patients with PNES is considered effective and can be an essential form of assistance for the reduction or cessation of episodes. .

Introdução: estima-se que o número de casos de pacientes com crises não epilépticas psicogênicas (CNEP) seja de 2 a 33 por 100 mil habitantes. O índice de CNEP corresponde ainda a, aproximadamente, 19% dos pacientes tratados como epilépticos. Os pacientes com CNEP são tratados como portadores de epilepsia refratária, chegando ao limite máximo do tratamento medicamentoso e sem a obtenção de resultados satisfatórios. Objetivo: relatar os efeitos do tratamento psicanalítico individual em pacientes com CNEP de forma a avaliar a evolução do quadro clínico de CNEP e verificar sua associação com gênero, tempo de crise, prejuízos sociais, afetivos e profissionais, bem como término do tratamento. Métodos: a casuística foi composta por 37 pacientes com diagnóstico de CNEP feito por meio da monitoração por vídeo-EEG. Foram realizadas sessões de tratamento psicanalítico: atendimento clínico individual com frequência semanal, com duração aproximada de 50 minutos e duração total de 48 sessões em 12 meses. Resultados: este estudo constatou elevado índice de sucesso no tratamento dos pacientes com CNEP: 29,7% (n = 11) de cessação/cura dos sintomas e 51,4% (n = 19) de redução das crises convulsivas. Foi constatada associação entre cessar ou reduzir as crises e gênero (p<0,01), religião (p<0,01) e término do tratamento (p<0,01). Conclusão: este estudo apontou eficácia do tratamento psicanalítico individual realizado com pacientes com CNEP, podendo ser considerada uma forma de assistência essencial para que haja decréscimo ou cessação das crises. .

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.

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.

Characteristics of Psychogenic Non-Epileptic Seizure Patients using MMPI Profiles

PURPOSE: The purpose of this study was to know psychological characteristics of psychogenic non-epileptic seizure (PNES) patients by analyzing profiles of Minnesota Multiphasic Personality Inventory (MMPI). In addition, we tried to investigate whether there are differences of MMPI profiles, depending on the gender and age.METHODS: We included 65 patients with non-epileptic psychogenic seizures. Their diagnosis was based on clinical features, provocative test and confirmed by video-EEG monitoring.RESULTS: The results of MMPI analysis did not show any statistically significant differences of quantitative scoring on the main clinical scales. However, additional analysis indicated that patients with PNES had some characteristics of more somatic complaints and depressive mood. According to sex difference, the MMPI profiles of female group showed an increase in the depression scale (D-Pt), whereas those of male group revealed an increased in the somatisation (Hs-Hy). According to age difference, MMPI profiles of adolescent group had the characteristics of personality pattern with a tendency toward somatisation. MMPI profiles of adult group had more depressive tendency. This study suggests that profiles of MMPI, according to the gender and age, can have different characteristics.CONCLUSIONS: Clinical consideration of those factors may be helpful for improving the care of PNES patients.

Epilepsy in patients with psychogenic non-epileptic seizures / Epilepsia em pacientes com crises não epilépticas psicogênicas

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 percent (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.
