RESUMO
Background and Aim: Dogs with idiopathic epilepsy (IE) experience a shortened lifespan, neurobehavioral changes, and an increased risk of comorbidities during the interictal period. There have been several reports of sudden death in humans with epilepsy, suggesting changes in cardiac rhythm secondary to seizures. In veterinary medicine, there are still no such conclusive studies. The present study aimed to evaluate blood pressure values, electrocardiographic findings, and laboratory parameters in dogs with IE treated with phenobarbital and to correlate these findings with possible cardiac alterations. Materials and Methods: Twenty-one dogs were divided into 11 healthy dogs and 10 idiopathic epileptic dogs for blood analysis, computerized electrocardiogram, and oscillometer-based blood pressure measurement. Results: QRS complex and S-T interval values differed significantly between groups, but blood pressure values were not significantly different. Conclusion: IE can occur with alterations in cardiac conduction and is a pathological condition.
RESUMO
Glycosylation is the most common protein and lipid post-translational modification in humans. Congenital disorders of glycosylation (CDG) are characterized by both genetic and clinical heterogeneity, presenting multisystemic manifestations, and in most cases are autosomal recessive in inheritance. The PIGN gene is responsible for the addition of phosphoethanolamine to the first mannose in the glycosylphosphatidylinositol (GPI)-anchor biosynthesis pathway, a highly conserved process that enables proteins to bind to the cell surface membrane. Here, we report a family with two siblings pediatric cases with the exact same compound heterozygous variants in PIGN. The (c.776T > C) variant of uncertain significance (VUS) together with a known pathogenic variant (c.932T > G), resulting in clinical features compatible with PIGN-related conditions, more specific the CDG. This is the first time that PIGN variant c.776T > C is reported in literature in individuals with PIGN-congenital disorder of glycosylation (PIGN-CDG), and the current submission in ClinVar by Invitae® is specifically of our case. Detailed clinical information and molecular analyses are presented. Here, we show for the first time two affected siblings with one pathogenic variant (c.932T > G) and the c.776T > C VUS in trans. In honor of the family, we propose the name Bella-Noah Syndrome for disorder.
RESUMO
Resumen Introducción: las crisis funcionales disociativas (CFD) son episodios que se asemejan a las crisis epilépticas, pero son causadas por diversos factores biopsicosociales. La forma en la que estos pacientes enfrentan los desafíos de su padecimiento se ha considerado un importante factor mantenedor. El objetivo de esta revisión sistemática es identificar las estrategias de afrontamiento utilizadas por pacientes adultos con CFD, y los instrumentos usados para evaluarlas. Método: la revisión se realizó siguiendo la guía PRISMA. Se hizo una búsqueda en las bases de datos Pubmed, Cochrane Library, Scielo, Science Direct y Lilacs. Resultados: once artículos cumplieron con los criterios de inclusión y se integraron en una síntesis narrativa. Los pacientes con CFD utilizan más estrategias de evitación y centradas en la emoción que la población general. Su uso excesivo se ha relacionado a una mayor psicopatología, una peor calidad de vida y mayor malestar frente al estrés. Por otro lado, la diversidad de instrumentos de evaluación del afrontamiento refleja la heterogeneidad del campo. Conclusiones: más investigaciones son necesarias para comprender las estrategias de afrontamiento de los pacientes con CFD y ofrecer un tratamiento más personalizado y efectivo.
Abstract Introduction: Functional dissociative seizures (FDS) are episodes that resemble epileptic seizures, but are caused by different biopsychosocial factors. The way in which these patients cope with the challenges of their condition has been considered an important maintaining factor. The aim of this systematic review is to identify the coping strategies used by adult patients with FDS, and the measures used to assess them. Methods: The review was conducted following the PRISMA guidelines. A search was conducted in Pubmed, Cochrane Library, Scielo, Science Direct and Lilacs databases. Results: Eleven articles met the inclusion criteria and were integrated into a narrative synthesis. FDS patients use more avoidance and emotion-focused strategies than the general population. Their excessive use has been related to greater psychopathology, poorer quality of life and greater distress in the face of stress. On the other hand, the diversity of coping assessment instruments reflects the heterogeneity of the field. Conclusions: More research is needed to understand the coping strategies of FDS patients and to offer more personalized and effective treatment.
RESUMO
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.

Se presenta el caso de dos hermanos portadores de MELAS, confirmado genéticamente, con historia de estados epilépticos recurrentes, acompañados de déficit neurológico, fallas de crecimiento, hiperlactacidemia y lesiones que simulan infartos cerebrales. Se destaca la presentación neurológica con estado epiléptico que permita tenerla presente en el correspondiente diagnóstico diferencial en salas de emergencia y hospitales pediátricos.
SUMMARY MELAS Syndrome is a mitochondrial disease associated with epileptic seizures. The case of two siblings with genetically confirmed MELAS is presented, with a history of recurrent status epilepticus accompanied by neurological deficits, failure to thrive, hyperlacticaemia, and brain lesions resembling strokes. The neurological presentation with epileptic status is highlighted to be considered in the corresponding differential diagnosis in emergency rooms and pediatric hospitals.
RESUMO
Pentylenetetrazol (PTZ) blocks the inhibitory action of GABA, triggering a Glu-mediated hyperexcitation of the dendritic spines in hippocampal CA1 pyramidal neurons that leads to the generation of epileptiform seizures. The aim of this work was to determine the effect of PTZ on the electrical activity of the hippocampal pyramidal neurons in male rats. Bipolar electrodes were implanted stereotaxically in the right and left hippocampal CA1 fields of adults, and PTZ (65 mg/kg) was administered i.p. Simultaneous recordings of the field activity and the firing rate (multiunitary activity, MUA) were analyzed at 10, 20, and 30 min post-administration of PTZ. Only rats that presented tonic-clonic seizures during the first 1-5 min after PTZ treatment were included in the study. The recordings of the field activity were analyzed in 4 frequency bands. In both the right and left hippocampal CA1 fields, the relative power corresponding to the slow waves (4-7 Hz) increased, while in the bands 13-30 Hz and 31-50 Hz, it decreased at 10, 20, and 30 min post-PTZ. MUA recordings were analyzed at four levels. The highest levels corresponded to larger amplitudes of the action potentials in the pyramidal neurons. The firing rates of the PTZ-treated rats did not differ from baseline but presented a significant decrement at 10, 20, and 30 min post-PTZ. The decreased firing rate of the hippocampal CA1 pyramidal neurons after PTZ treatment could be associated with plastic changes of dendritic spines along with some microenvironmental adaptations at synaptic level, after neuronal PTZ-mediated hyperexcitation.

Resumen Recientemente la Liga Internacional contra la Epilepsia (ILAE) socializó la clasificación propuesta para síndromes epilépticos de inicio neonatal y hasta los primeros 2 años de edad, dividiéndolos en síndromes epilépticos autolimitados y las encefalopatías epilépticas y del desarrollo (DEEs). En esta revisión nos dedicaremos a las DEEs, definidas como trastornos donde existe deterioro del desarrollo relacionado tanto con la etiología subyacente independiente de la actividad epileptiforme como con la encefalopatía epiléptica. Estas incluyen en el período neonatal la encefalopatía epiléptica infantil temprana o síndrome de Ohtahara y la encefalopatía mioclónica temprana, ahora agrupadas bajo la denominación de encefalopatías epilépticas y del desarrollo infantil temprano (EIDEE). El síndrome de espamos epilépticos infantiles, la epilepsia de la infancia con crisis migratorias y el síndrome de Dravet forman parte de las encefalopatías de inicio en el lactante. La importancia del reconocimiento temprano de las encefalopatías epilépticas radica no solo en el control de las crisis epilépticas, sino en detener el deterioro intentando cambiar el curso de la enfermedad. Es fundamental conocer la etiología evitando medicamentos que puedan exacerbar las crisis y empeorar el curso, aplicando medicina de precisión así como identificando pacientes candidatos a cirugía temprana de epilepsia.
Abstract The International League Against Epilepsy (ILAE) recently socialized the proposed classification for epileptic syndromes of neonatal onset and up to the first 2 years of age, dividing them into self-limited epileptic syndromes and epileptic and developmental encephalopathies (DEEs). In this review we will focus on DEEs, defined as disorders in which there is developmental impairment related to both the underlying aetiology independent of epileptiform activity and epileptic encephalopathy. These include early infantile epileptic encephalopathy or Ohtahara syndrome and early myoclonic encephalopathy in the neonatal period, now grouped under the name of epileptic and early childhood developmental encephalopathies (EIDEE). Infantile epileptic spasms syndrome, childhood epilepsy with migratory crises and Dravet syndrome are part of the infant-onset encephalopathies. The importance of early recognition of epileptic encephalopathies lies not only in the control of epileptic seizures, but also in stopping deterioration by trying to change the course of the disease. It is essential to know the etiology, avoiding medications that can exacerbate seizures and worsen the course, applying precision m edicine as well as identifying candidate patients for early epilepsy surgery.

Introduction: Epileptic seizures during non-ketotic hyperglycemia (NKH) represent a rare complication of uncontrolled diabetes mellitus. The definition associates a blood sugar level > 200mg/dL (11mmol/L), hyperosmolality, absence of ketosis, dehydration and seizure control after normalization of blood sugar levels. Material and methods: This retrospective observational study included patients hospitalized for epileptic seizures and NKH in the Cayenne Hospital Center between January 2010 and June 2020. The clinical, biological, and radiological results were collected. Results: 18 out of 228 (7.9%) patients with both diabetes and epileptic seizures had NKH. The mean age of the 12 women and 6 men was 64.8 years. In 8 patients, brain imaging did not show acute lesions and the seizures disappeared with control of hyperglycemia by hydration and insulin. In 6 patients, the seizures revealed a stroke, hemorrhagic in 4 cases, ischemic in 2 cases. 4 patients had a seizure in a context of known vascular epilepsy. The epileptic seizures were mainly focal seizures with motor symptoms that could be repeated, focal to bilateral tonic-clonic or focal status. Conclusion: Seizures in NKH are symptomatic of an acute brain lesion or vascular epilepsy more than 1 in 2 times. However, isolated NKH can cause seizures with a suggestive brain MRI.

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.
RESUMO
The brain is made up of billions of neurons, which control all actions performed by us. In epilepsy, the pattern order of brain signals is altered, causing epileptiform discharges in an individual's brain. Approximately 1% of the world population has epilepsy and, therefore, there is a need for studies that can help in the diagnosis and treatment of this disorder. The objective of this work is to develop a machine learning-based approach to predict epileptic seizures using non-invasive electroencephalography (EEG). Therefore, the classification of interictal and preictal states was performed using the CHB-MIT database. The algorithm was developed to predict epileptic seizures in multiple subjects using a patient-independent approach. The Discrete Wavelet Transform was used to perform the decomposition of the EEG signals in 5 levels and, as characteristics, the Spectral Power, the Mean and the Standard Deviation were studied, in order to analyze which one would present the best result and as a classifier, the Supported Vector Machine (SVM). The study achieved an accuracy of 92.30%, 84.60% and 76.92% for the Power, Standard Deviation and Mean characteristics, respectively.
RESUMO
El síndrome de Sturge-Weber es un trastorno neurocutáneo, congénito, esporádico e infrecuente que afecta aproximadamente a 1 de cada 20 000 a 50 0000 nacidos vivos y que se relaciona con una mutación genética activadora somática en GNAQ. Clínicamente se caracteriza por la presencia de una mácula en vino de Oporto en la piel de territorio trigeminal, angiomatosis leptomeníngea y glaucoma. Puede asociarse a diferentes manifestaciones clínicas, de las cuales las crisis epilépticas representan la manifestación neurológica más frecuente que se asocia a un deterioro cognitivo importante en estos pacientes. En el presente artículo se realiza una revisión descriptiva de la literatura sobre los aspectos etiológicos, fisiopatológicos, de clasificación, clínicos, diagnósticos y del tratamiento del síndrome de Sturge-Weber.
Sturge-Weber syndrome is a rare, sporadic, congenital neurocutaneous disorder affecting approximately 1 in 20,000 to 50,000 live births that is associated with a somatic activating gene mutation in GNAQ. Clinically it is characterized by the presence of a port wine stain on the skin of trigeminal territory, leptomeningeal angiomatosis and glaucoma. It can be associated with different clinical manifestations, of which the epileptic seizures represents the most frequent neurological manifestation associated with significant cognitive impairment in these patients. This article makes a descriptive review of the literature on the etiological, pathophysiological, classification, clinical, diagnostic and treatment aspects of Sturge-Weber syndrome.

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.

Resumen Los eventos no epilépticos psicógenos (ENEP) son episodios paroxísticos descritos como cambios conductuales, alteraciones sensorio-sensitivas, o manifestaciones motoras que se asemejan a las crisis epilépticas pero sin mostrar actividad epileptiforme subyacente, no son producidos deliberadamente por el individuo, y responden a mecanismos multifactoriales de índole biopsicosocial. La información epidemiológica es limitada debido a la naturaleza heterogénea de la población afectada, así como a la escasa accesibilidad al videoelectroencefalograma (vEEG) necesario para su diagnóstico. En este contexto, es necesaria la convergencia de dos elementos importantes: historia clínica detallada (características clínicas sugerentes de ENEP e identificación de los factores asociados) y la ausencia de cambios electroencefalográficos en el vEEG durante el episodio. La evaluación psicológica provee información adicional relevante para la corroboración diagnóstica y para su manejo. El diagnóstico debe realizarse de manera oportuna, para evitar complicaciones en su evolución y tratamiento. Es vital una actitud positiva y alentadora hacia el/la paciente al momento de comunicarle su diagnóstico, así como la coordinación entre el neurólogo tratante y los profesionales de salud mental involucrados en el manejo y seguimiento del caso. La psicoterapia cognitiva conductual, asociada a psicofármacoterapia -cuando pertinente-, constituyen el tratamiento más eficaz de estos pacientes. Existen limitados estudios en Latinoamérica sobre aspectos epidemiológicos y clínico-evolutivos de pacientes con ENEP, por lo que más investigación y publicaciones respecto a esta problemática son indispensables dado su impacto sobre la calidad de vida de los pacientes y sobre el costo de su manejo en los sistemas de salud.
Summary Psychogenic Non-Epileptic Events (PNEE) are paroxysmal episodes described as behavioral changes, sensory- sensitive disturbances, or motor manifestations that resemble epileptic seizures without showing underlying epileptiform activity, are not deliberately produced by the individual, and respond to multifactorial biopsychosocial mechanisms. Epidemiological information is limited due to the heterogeneous nature of the affected population, and to the limited accessibility to the video electroencephalogram (vEEG) necessary for its diagnosis. In such context, the convergence of two important elements is necessary: a detailed clinical history (clinical characteristics suggestive of PNEE, and identification of the associated factors), and the absence of electroencephalographic "ictal" changes in the vEEG. A psychological evaluation provides additional information, relevant for the diagnostic corroboration and management. The diagnosis must be made in a timely manner, to avoid complications in its evolution and treatment. A positive and encouraging attitude to the patient is vital when informing him/her of the diagnosis, as it also is the coordination between the treating neurologist and mental health professionals involved in the management and monitoring of the case. Cognitive behavioral psychotherapy, associated with psychopharmacotherapy -when needed-- constitute the most effective treatment approach for these patients. There are limited studies on the current epidemiological and clinical evolution of patients with PNEE in Latin America, and additional research regarding this problem is much needed, given its impact on the quality of life of the patients and on the cost of its management in the health care systems.
RESUMO
PURPOSE: To examine the effects of a three-session psychoeducational intervention on patients diagnosed with psychogenic non-epileptic seizures (PNES) in an Argentinian public hospital. It was hypothesized that patients would experience improvements in their understanding of PNES, illness perception and affective scores, but might not necessarily experience a significant change in post-traumatic and dissociative symptoms and in seizure frequency. METHODS: This study included 12 patients (10 women, 2 men) who were invited to participate in a psychoeducational group after receiving a V-EEG confirmed diagnosis of PNES. The group consisted of 3 sessions lasting 2â¯h each. Pre and post measures included Psychoeducational Intervention Questionnaire, State-Trait Anxiety Inventory, Beck Depression Inventory-II, Brief Illness Perception Questionnaire, Posttraumatic Stress Disorder Diagnostic Scale 5, Dissociative Experiences Scale (DES-M). RESULTS: This psychoeducational intervention produced results that were similar to interventions reported in US and European studies with regard to changes on psychological measures. Moreover, many patients also reported (on the final day of the intervention) a decrease in seizure frequency. All patients reported that participating in the intervention was a positive experience. Also, all but one patient referred that the participation in the group would have a positive impact on their quality of life. CONCLUSIONS: Psychoeducational interventions appear to have had positive results in Argentinian patients with PNES. This is initial step in the design of empirically based psychoeducational/supportive initiatives for patients in South America.

RESUMEN Introducción: Un imitador de ictus es toda aquella patología no vascular que se presenta como un ictus isquémico agudo. La presentación clínica, factores epidemiológicos, el tiempo de inicio, la distribución vascular y la disponibilidad de pruebas de imagen, son factores que ayudan a diferenciarlos. Caso clínico: Presentamos un caso, de una mujer de la tercera edad que fue llevada a urgencias por hemiparesia izquierda de cinco horas de evolución. La evolución clínica y las pruebas complementarias permitieron excluir el diagnóstico de ictus isquémico agudo. La semiología fue explicada por una parálisis de Todd prolongada que se comportó como imitador de ictus en la fase aguda y las crisis epilépticas se produjeron en el contexto de una trombosis venosa cerebral. Comentarios: Los imitadores de ictus, al contrario del ictus isquémico agudo, ocurren en pacientes más jóvenes, tienen menos factores de riesgo vascular, menor puntuación de NIHSS, menos afasia y disfagia. Las principales causas son crisis epilépticas y síncopes. Deben considerarse también migrañas, neoplasias, alteraciones tóxicas o metabólicas, encefalopatías y trastornos funcionales. Realizar un estudio neurovascular completo y pruebas dirigidas nos permitirán el diagnóstico.
ABSTRACT Introduction: A stroke mimic is any non-vascular pathology that presents as an acute ischemic stroke. The clinical presentation, the epidemiological factors, the time to onset, vascular distribution and the availability of imaging tests are factors that help to differentiate them. Case report: We present a case, of a woman of the third age who was taken to the emergency department due to a five-hour history of left hemiparesis. The clinical evolution and the supplementary tests allowed to exclude the diagnosis of acute ischemic stroke. The semiology was explained by a prolonged Todd's palsy that behaved as a stroke mimic at the acute phase and the seizures occurred in the context of a cerebral venous thrombosis. Comments: Stroke mimics, in contrast to acute ischemic stroke, occur in younger patients, have fewer vascular risk factors, lower NIHSS score, less aphasia and dysphagia. The main causes are seizures and syncope. Migraines, neoplasms, toxic or metabolic alterations, encephalopathies and functional disorders should also be considered. To perform a complete neurovascular study and directed tests will allow us to make the diagnosis.

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.
