RESUMEN
OBJECTIVE: The point after which non-convulsive status epilepticus (NCSE) can cause permanent damage remains to be elucidated. The aim of this study was to analyze the association between time to resolution and long-term outcomes in NCSE. METHODS: We performed a retrospective study of all patients with focal NCSE without consciousness impairment at two tertiary care hospitals in Spain. All the data were registered prospectively and the study period was December 2014-May 2018. We collected information on demographics, SE etiology, time to administration of different lines of treatment, time to NCSE resolution, and outcomes at discharge, 1â¯year, and 4â¯years. Clinical outcome was prospectively categorized as good (return to baseline function) or poor (new disability and death). RESULTS: Seventy-four patients with a mean (±SD) age of 63.4⯱â¯17.5â¯years and a mean follow-up time of 2.4⯱â¯2.2â¯years were studied. A poor outcome at discharge was associated with a potentially fatal etiology (pâ¯<â¯0.001), EMSE score (Epidemiology-based Mortality Score in Status Epilepticus) (pâ¯=â¯0.012), lateral periodic discharges on EEG (pâ¯=â¯0.034), and occurrence of major complications during hospitalization (pâ¯=â¯0.007). An SE duration of >100â¯h was clearly associated with a worse outcome (pâ¯<â¯0.001). In the multiple regression analysis, the only independent predictors of a poor outcome at discharge were an SE duration of >+100 hours (pâ¯=â¯0.001), a potentially fatal etiology (pâ¯=â¯0.001), and complications during hospitalization (pâ¯=â¯0.010). An SE duration of >100 hours retained its value as the optimal cutoff point for predicting poor outcomes at both 1â¯year (pâ¯=â¯0.037) and 4â¯years (pâ¯=â¯0.05). Other predictors of poor long-term outcomes were a potentially fatal etiology (pâ¯<â¯0.001) and EMSE score (pâ¯=â¯0.034) at 1â¯year, and progressive symptomatic etiology at 4â¯years (pâ¯=â¯0.025). SIGNIFICANCE: In patients with focal NCSE without consciousness impairment, a potentially fatal etiology and an SE duration of >100â¯h were associated with poor short-term and long-term outcomes.

BACKGROUND AND PURPOSE: The prognosis of status epilepticus (SE) depends on the time between onset and the diagnosis and start of treatment. Our aim was to design a scale with predictive value for pre-hospital diagnosis of SE. METHODS: This was a retrospective study of 292 patients who attended the emergency department for an epileptic seizure. A total of 49 patients fulfilled the criteria for SE. We recorded the patients' history and clinical features. Variables independently associated with SE were combined to design a clinical scale. The performance of the scale was evaluated in a validation dataset of 197 patients. RESULTS: A total of 50.3% of the patients were male and the mean age was 55.9 years. The following features were more prevalent in patients with SE: abnormal speech (79.6% vs. 18.9%, P < 0.001), eye deviation (69.4% vs. 14.0%, P < 0.001), automatism (22.4% vs. 6.3%, P < 0.001), hemiparesis (24.5% vs. 10.9%, P = 0.011), state of stupor/coma (46.9% vs. 4.2%, P < 0.001) and number of pre-hospital seizures, i.e. two (34.7% vs. 4.5%, P < 0.001) or more than two (51.0% vs. 0.4%, P < 0.001). Based on these findings, we designed a scale that scored 1 point each for presence of abnormal speech, eye deviation, automatism and two seizures, and 2 points for more than two seizures. The predictive capacity of the scale for identifying SE in the validation dataset was 98.7% (95% confidence interval, 97.3%-100%) and 85.4% of patients with a score >1 had SE. CONCLUSIONS: A score >1 on the ADAN scale is a robust predictor of the diagnosis of SE in patients who experience an epileptic seizure. This scale may be a useful tool for clinical use and warrants further investigation.

PURPOSE: New-onset seizures (NOS) are a common reason for emergency department (ED) consultations. Decisions regarding treatment and further examinations are made based on the initial evaluation. We aimed to evaluate the reliability of the early syndromic diagnosis in NOS and find predictive factors to establish a consistent early diagnosis based on the semiology and prompt supplementary examinations. METHODS: We recruited patients attended in our ED for NOS over 2 years (2014-2015), excluding patients with a loss of consciousness of suspected non-epileptic origin. All patients were assessed by a neurologist. A baseline diagnosis was established according to clinical findings and neuroimaging/EEG data. Over 1 year of follow-up in our Epilepsy Unit, a definite diagnosis was made based on clinical progress and further examinations. RESULTS: 116 patients were recruited (mean age 56.5⯱â¯22.1â¯years; 50% women). 47% were seizures of unknown cause. The concordance index between the baseline and definite diagnosis was κâ¯=â¯0.662 (the diagnosis changed during follow-up in 25% of patients). Focal epilepsy of unknown cause was the baseline diagnosis that most often changed at follow-up (diagnostic change, 41.2%; pâ¯<â¯0.001). Lesions detected on CT-scanning and EEG abnormalities predicted the final diagnosis with the greatest accuracy (pâ¯=â¯0.009 and pâ¯=â¯0.026, respectively). Pathological findings in the MRI studies performed and seizure recurrence were not key factors for diagnostic changes. CONCLUSION: Despite prompt examinations, the baseline epilepsy diagnosis changes within a short time period in 25% of patients. The presence of neuroimaging lesions and EEG abnormalities was associated with the greatest diagnostic accuracy in these cases.

Las anteriores Guías oficiales de práctica clínica en epilepsia elaboradas por el Grupo de Estudio de Epilepsia de la Sociedad Española de Neurología (GE-SEN) estaban basadas en la opinión de expertos. La actual Guía de práctica clínica (GPC) en epilepsia se basa en el método científico que extrae recomendaciones a partir de evidencias científicas constatadas. Su principal función es disminuir la variabilidad de la práctica clínica a través de la homogeneización de la práctica médica. Alcance y objetivos: Esta GPC se centra en la atención integral de personas afectadas por una epilepsia, como síntoma principal y predominante, independiente de la edad de inicio y ámbito asistencial. Metodología: 1) Constitución del grupo de trabajo integrado por neurólogos del GE-SEN, con la colaboración de neuropediatras, neurofisiólogos y neurorradiólogos; 2) determinación de los aspectos clínicos a cubrir: diagnóstico, pronóstico y tratamiento; 3) búsqueda y selección de la evidencia científica relevante; 4) formulación de recomendaciones basadas en la clasificación de las evidencias científicas disponibles. Resultados: Contienen 192 recomendaciones. El 57% son de consenso entre autores y editores, como consecuencia del desconocimiento en muchos campos de esta patología. Conclusiones: Esta GPC, en epilepsia, con una metodología formal y rigurosa en la búsqueda de evidencias explícitas donde ha sido posible, formula recomendaciones extraídas de las mismas. En este artículo incluimos el capítulo de la GPC dedicado a situaciones de urgencia en crisis epilépticas y epilepsia, que pueden presentarse como una primera crisis epiléptica, una evolución desfavorable en un paciente con una epilepsia conocida o en su forma más grave como un estado epiléptico
Previous Official Clinical Practice Guidelines (CPGs) in Epilepsy were based on expert opinions and developed by the Epilepsy Study Group of the Spanish Neurological Society (GE-SEN). The current CPG in epilepsy is based on the scientific method, which extracts recommendations from published scientific evidence. A reduction in the variability in clinical practice through standardization of medical practice has become its main function. Scope and objectives: This CPG is focused on comprehensive care for individuals affected by epilepsy as a primary and predominant symptom, regardless of the age of onset and medical policy. Methodology: 1. Creation of GE-SEN neurologists working group, in collaboration with Neuropediatricians, Neurophysiologists and Neuroradiologists. 2. Identification of clinical areas to be covered: diagnosis, prognosis and treatment. 3. Search and selection of the relevant scientific evidence. 4. Formulation of recommendations based on the classification of the available scientific evidence. Results: It contains 161 recommendations of which 57% are consensus between authors and publishers, due to an important lack of awareness in many fields of this pathology. Conclusions: This Epilepsy CPG formulates recommendations based on explicit scientific evidence as a result of a formal and rigorous methodology, according to the current knowledge in the pre-selected areas. This paper includes the CPG chapter dedicated to emergency situations in seizures and epilepsy, which may present as a first seizure, an unfavorable outcome in a patient with known epilepsy, or status epilepticus as the most severe manifestation

Introducción: El pronóstico en la epilepsia implica la probabilidad de alcanzar la remisión de las crisis epilépticas (CE) de forma espontánea o bajo tratamiento con fármacos antiepilépticos (FAE), o no conseguirla a pesar de un tratamiento oportuno. El tratamiento con FAE es recomendable después de una segunda CE no provocada. Tras una primera CE la decisión de iniciar o no el tratamiento con FAE depende de los riesgos de recurrencia y las ventajas o inconvenientes del tratamiento con FAE. El objetivo del tratamiento es alcanzar la ausencia de CE sin efectos adversos (EA). La selección de los FAE se realiza según tipo de epilepsia y las características demográficas y clínicas del paciente. Desarrollo: Búsqueda de artículos en Pubmed y recomendaciones de las Guías de Práctica Clínica (GPC) y Sociedades Científicas más relevantes referentes a pronóstico de la epilepsia y su tratamiento. Se clasifican las evidencias y recomendaciones según los criterios pronósticos del Oxford Center for Evidence-Based Medicine (2001) y de la European Federation of Neurological Societies (2004) para las actuaciones terapéuticas. Conclusiones: La mayoría de pacientes que inician una epilepsia consigue el control de sus CE. La mayoría de los FAE disponibles son útiles para el control de cualquier tipo de CE, su elección depende de las características del paciente. Se debe iniciar el tratamiento en monoterapia y a la menor dosis eficaz del FAE elegido, que suele controlar las CE en la mitad de los pacientes y con buena tolerancia. Ante la falta de eficacia del primer FAE, debe intentarse otra terapia alternativa, a ser posible en monoterapia, antes de instaurar una politerapia. Las posibilidades de control de las CE disminuyen con sucesivos fracasos terapéuticos
Introduction: Prognosis in epilepsy refers to the probability of either achieving seizure remission (SR), whether spontaneously or using antiepileptic drugs (AED), or failing to achieve control of epileptic seizures (ES) despite appropriate treatment. Use of AED is recommended after a second unprovoked ES. For a first episode, the decision of whether or not to start drug treatment depends on the risk of recurrence and the advantages or disadvantages of the antiepileptic drug. The main goal of treatment is achieving absence of ES without adverse effects (AE). AED is selected according to epilepsy type and the demographic and clinical characteristics of the patient. Development: A PubMed search located articles and recommendations by the most relevant scientific societies and clinical practice guidelines concerning epilepsy prognosis and treatment. Evidence and recommendations are classified according to the prognostic criteria of the Oxford Centre for Evidence-Based Medicine (2001) and the European Federation of Neurological Societies (2004) for therapeutic actions. Conclusions: Most newly diagnosed epileptic patients achieve good control over their ES. The majority of the AEDs available at present provide effective control over all types of ES, and choice therefore depends on the patient's individual characteristics. Treatment should be initiated as monotherapy at the lowest effective dose, which in half of all patients provides ES control and is well tolerated. In cases in which the first AED is not effective, alternative therapy should be started, and monotherapy should be employed before combination therapy where possible. The probability of achieving good control over ES decreases with each successive treatment failure

UNLABELLED: In animal models, SE duration is related to epileptogenesis. Data in humans are scarce, mainly in NCSE; therefore, we aimed to study the prognosis of SE de novo and which factors may influence subsequent development of epilepsy. METHODS: We evaluated patients with SE without previous epilepsy at our hospital (February 2011-February 2014), including demographics, etiology, number of AEDs, duration of SE, mortality, and occurrence of seizures during follow-up. RESULTS: Eighty-nine patients were evaluated. Median age was 69 (19-95) years old. Among them, 33.7% were convulsive. Regarding etiology, 59 were considered acute symptomatic (41 lesions, 18 toxic-metabolic), 17 remote or progressive symptomatic, and 13 cryptogenic. The median recovery time was 24h (30 min-360 h). In-hospital mortality was 29% (n = 26). After a median follow-up of 10 months, 58.7% of survivors (n = 37) showed seizures. Subsequently, we analyzed which factors might be related to the development of epilepsy, and we found that epilepsy development was more frequent with longer SE duration (37 vs. 23 h, p = 0.004); furthermore, patients with a toxic-metabolic etiology developed epilepsy less frequently (33% vs. 67%; p = 0.022). Epilepsy was also correlated (tendency) with focal SE (p = 0.073), a lesion in neuroimaging (p = 0.091), and the use of 2 or more AEDs (p = 0.098). Regarding SE duration, a cutoff of above 24h was clearly related to chronic seizures (p = 0.014); however, combining etiology and duration, the association of longer SE and epilepsy was significant in acute lesional SE (p = 0.034), but not in epilepsy with cryptogenic or remote/progressive etiology. After a logistic regression, only a duration longer than 24h (OR = 3.800 (1.277-11.312), p = 0.016) was found to be an independent predictor of the development of epilepsy. CONCLUSION: In patients with SE, the longer duration is associated with an increased risk of subsequent epilepsy at follow-up, mainly in symptomatic SE due to an acute lesion. It is unclear if it might be the result of a more severe injury causing both prolonged seizures and subsequent epilepsy, and therefore whether more aggressive treatment in this group might avoid this possibility. Most of the patients with cryptogenic or remote/progressive SE developed epilepsy regardless of SE duration. This article is part of a Special Issue entitled "Status Epilepticus".

UNLABELLED: Patients with malignant middle cerebral artery (MCA) infarctions who have undergone craniectomy are susceptible to the development of vascular epilepsy. Our objective was to study the factors that might influence the occurrence of seizures in this group of patients. MATERIALS AND METHODS: All patients who developed malignant MCA infarction and had undergone decompressive craniectomy in our center between November 2002 and January 2014 were evaluated. In the subsequent follow-up, we evaluated the clinical outcomes and attempted to identify the factors that were related to the occurrence of seizures. RESULTS: We evaluated a total of 80 patients. The median time at which the craniectomy was performed was 40.5h after the stroke. Seizures occurred in 47.5% of all patients. The mortality rate within the first week was 16%, and of those who survived 53.7% developed seizures; 9% of these seizures were acute symptomatic, and 44.8% were remote. The median onset of remote seizures was seven months, and the majority of these were motor seizures with generalization. Notably, the patients with seizures exhibited longer delays from stroke to craniectomy, greater involvements of the temporal lobe and a higher rate of post-craniectomy recanalization of the occluded artery. Regarding the timing of the surgeries, a significantly greater proportion of those who underwent surgery more than 42h after the stroke developed epilepsy (p=0.004). Logistic regression revealed that only prolonged delay (>42h) independently predicted the development of epilepsy (OR 5.166; IC 95% 1.451-18.389; p=0.011). CONCLUSIONS: More than half of patients with malignant MCA infarcts who underwent decompressive craniectomy developed epilepsy. The occurrence of seizures in these patients was related to the delay to the performance of the craniectomy.

OBJECTIVE: With the objective of evaluating the efficacy and tolerability of topiramate (TPM) in resistant epilepsy, we did a retrospective, open, multicentric analysis of 56 patients aged over 15 years in whom TPM was given as the second, third or fourth drug. All patients had already been on treatment for at least 18 months when topiramate was started. The average follow up was 27.2 months. RESULTS: At the close of the study 16% of the patients were asymptomatic, 23% had a 75% reduction in seizures and 36% a 50% reduction. The drug was withdrawn in 25% of the cases. The adverse effects noted were: nephrolithiasis, asthenia, loss of hair, diarrhoea, weight loss of over 5kg., agitation, aggressiveness, language disorders, ataxia, tremor, somnolence and confusion. The drug had to be suspended when these adverse effects affected the central nervous system moderately or severely, and when there were general effects such as renal calculi in one case and weight loss associated with symptoms which worried the patients in two cases. CONCLUSIONS: Thus, TPM is an effective drug in refractory epilepsy and most patients continue on this treatment. The side effects are typical of the drug, and although there is no risk to life, the patient should be warned of them.

Recent studies by Isojärvi et al. have raised the issue of an increased incidence of polycystic ovary syndrome (PCOS) in women with epilepsy treated with valproate (VPA) and have proposed replacement with lamotrigine (LTG). Polycystic ovaries (PCO) are a common finding, with a prevalence >20% in the general population, and are easily detected by pelvic or vaginal ultrasonography, whereas PCOS is comparatively rare: few women with PCO have fully developed PCOS, which includes hirsutism, acne, obesity, hypofertility. hyperandrogenemia, and menstrual disorders. From an extensive review of the current literature, it appears that there are no reliable data on the actual prevalence of PCOS in normal women and in women with epilepsy. The pathogenesis of PCO is multifactorial, including genetic predisposition and the intervention of environmental factors, among which weight gain and hyperinsulinism with insulin resistance may play a part. The roles of central (hypothalamic/pituitary), peripheral, and local ovarian factors are still debated. PCO and PCOS appear to be more frequent in women with epilepsy, but there are no reliable data showing a greater prevalence after VPA. The recent studies by Isojärvi et al. may have been biased by the retrospective selection of patients. To date, there is no reason to contraindicate the use of VPA in women with epilepsy. However, patients should be informed about the risk of weight gain and its consequences.

OBJECTIVE: To analyze the cost of monotherapeutic treatment of patients with newly diagnosed epilepsy. PATIENTS AND METHODS: We analysed the cost of treatment with lamotrigine (LTG), carbamazepine (CBZ), phenytoin (PHT) and valproic acid (VPA) using published data regarding the efficacy and tolerability of comparative clinical trials of monotherapy. We established a model of treatment for newly diagnosed patients during the first 12 months after diagnosis. A panel of doctors reached a consensus on the use of resources, costs and model of treatment in Spain. We made a cost minimization analysis for economic assessment of the data based on the fact that randomized trials indicated that CBZ, LTG, PHT and VPA ware of similar efficacy. Analysis was done as 'intention to treat'. Only direct medical costs were considered. RESULTS: In Spain treatment with LTG is twice or three times as expensive as treatment with the other drugs. Sensitivity analysis showed that variations in the interval of use of resources and of costs (defined by the panel of doctors) did not significantly alter the results. CONCLUSIONS: Treatment with LTG is more expensive than treatment with the classical drugs. In view of the methodological limitations of this study, further analysis is necessary, particularly of the methodology of cost-benefit, to evaluate the economic impact of the new antiepileptic drugs and determine whether their use is justified as drugs of first choice.

Objetivo. Analizar el coste del tratamiento en monoterapia de los pacientes con epilepsia de reciente comienzo. Pacientes y métodos. Se analizó el coste del tratamiento con lamotrigina (LTG), carbamacepina (CBZ), fenitoína (PHT) y ácido valproico (VPA) utilizando datos publicados sobre eficacia y tolerabilidad de los ensayos clínicos comparativos en monoterapia. Se estableció un modelo de tratamiento de pacientes con epilepsia de reciente comienzo durante los primeros 12 meses tras su diagnóstico. Un panel de médicos consensuó el uso de recursos, costes y el modelo de tratamiento en nuestro país. Se llevó a cabo un análisis de coste-minimización para evaluar económicamente los datos, basado en que los ensayos aleatorizados indicaban que CBZ, LTG, PHT y VPA eran de eficacia similar. El análisis se realizó como `intención de tratar'. Únicamente se consideraron los costes médicos directos. Resultados. En nuestro país, el tratamiento con LTG es entre dos y tres veces más costoso que con las otras medicaciones. Un análisis de sensibilidad demostró que variaciones en el intervalo de uso de recursos y de costes (definido por el panel de médicos) no alteraban de forma significativa los resultados. Conclusiones. El tratamiento con LTG es más costoso que el tratamiento con fármacos clásicos. Dadas las limitaciones metodológicas del actual estudio, se precisan nuevos análisis, especialmente con metodología de coste-beneficio, para valorar el impacto económico de los nuevos antiepilépticos y determinar si está justificada su utilización como fármaco de primera elección (AU)

BACKGROUND AND OBJECTIVE: Patients with cortical malformations often have intractable seizures and are candidates for epilepsy surgery. Within an unselected series of patients with various forms of cortical malformation, nine patients with multilobar polymicrogyria had electrical status epilepticus during sleep (ESES) accompanied by infrequent focal motor seizures. Eight patients also had intractable atonic drop attack seizures. Because ESES usually is accompanied by a good long-term seizure prognosis, the objective of this study was to examine ESES outcome among patients with a structural lesion that is usually highly epileptogenic and has a low seizure remission trend. METHODS: The nine patients had follow-up periods lasting 4 to 19 years. All underwent brain MRI, serial sleep EEG recordings, and cognitive testing during and after ESES. RESULTS: ESES and drop attack seizures appeared between the ages of 2 and 5 years (mean, 4 years) and ceased between the ages of 5 and 12 years (mean, 8 years). At the last visit patients were 8 to 23 years of age (mean, 14.5 years) and were either seizure free or had very infrequent focal motor seizures during sleep. Three patients were free from antiepileptic drugs. In no patient was definite cognitive deterioration apparent after ESES in comparison with earlier evaluations. CONCLUSIONS: Age-related secondary bilateral synchrony underlying ESES may be facilitated in multilobar polymicrogyria. The good seizure outcome contrasts with that usually found in the presence of cortical malformations. For children with polymicrogyria and drop attack seizures, surgical treatment of the epilepsy should be considered cautiously, and sleep EEG recordings should be performed systematically.

Our aim was to delimit prognostic factors in supratentorial stroke based on data obtained upon hospitalization. We studied two series of patients, the first being 150 with brain infarct and the second 135 having intracerebral haemorrhage. We analyzed: age, Glasgow and Canadian scales, glucose and urgence haemogram and the size of the lesion across its greatest diameter using computerized tomography (CT). Follow-up time was until death or one year after the stroke. Those who lived longer than one year after were subclassified according to the Rankin scale as < 3 and > or = 3. There was a significant difference between those who survived for less than one month and those surviving more than one year: their age (p < 0.01), average score on the scale (p < 0.001) and size of infarct (p < 0.05) or haematoma (p < 0.001). The Rankin subgroups < 3 and > or = 3 also differed significantly with regard to age. Noteworthy were the unfavourable data: Glasgow < 10 points and Canadian < 5 points, in infarcts > 6 cm and haematomas > 4 cm in diameter. We comment on other evolutionary variables which may influence prognostic assessment such as clinical deterioration or CT sensitivity of the infarct depending on the carry-out time.

The prognostic value of a group of parameters recorded upon hospital admission was assessed in a series of 135 supratentorial hemorrhages. The patients were divided into 3 groups based on survival < 30 days, between 30 days and 1 year, or > 1 year. Patients in the group with the shortest survival period were older; had more Glasgow scale scores < or = 10 and more Canadian scale scores < or = 5; had more hematomas > or = 4 cm in diameter revealed in computerized tomography with frequent midline shift and frequent ventricular hemorrhagic invasion; had higher stress reaction (hyperglycemia, leukocytosis and heart arrhythmia). Cholesterinemia, however, was lower in the shortest survival group. A range of quality of life was observed in the group (44%) with survival longer than 1 year. The subgroup with motor independence (Rankin < 3) (19%) differed from those with less motor independence (Rankin > or = 3) in that they were younger, more often had mean scores > or = 5 on the Canadian scale and normal blood pressure levels. We conclude that prognostic value of the clinical evaluation scales used, along with age and size of hematoma, was good.

The EEG records of 64 patients affected by a symptomatic severe partial epilepsy have been reviewed retrospectively. The epilepsy started before age 12. The follow-up was at least 5 years after the onset of the disease. In a longitudinal study of interictal EEG, the following parameters were studied: normal or slightly abnormal EEG records at the onset, late appearance of abnormalities of background, multifocal abnormalities and generalized spike and wave discharges. The study of ictal EEG was performed in 32 patients: a good correlation with the interictal and ictal site of the discharges was found. The EEG semeiology of the seizures persisted unchanged throughout the evolution.
