Implications for driving based on the risk of seizures after ischaemic stroke.

BACKGROUND: In addition to other stroke-related deficits, the risk of seizures may impact driving ability after stroke. METHODS: We analysed data from a multicentre international cohort, including 4452 adults with acute ischaemic stroke and no prior seizures. We calculated the Chance of Occurrence of Seizure in the next Year (COSY) according to the SeLECT2.0 prognostic model. We considered COSY<20% safe for private and <2% for professional driving, aligning with commonly used cut-offs. RESULTS: Seizure risks in the next year were mainly influenced by the baseline risk-stratified according to the SeLECT2.0 score and, to a lesser extent, by the poststroke seizure-free interval (SFI). Those without acute symptomatic seizures (SeLECT2.0 0-6 points) had low COSY (0.7%-11%) immediately after stroke, not requiring an SFI. In stroke survivors with acute symptomatic seizures (SeLECT2.0 3-13 points), COSY after a 3-month SFI ranged from 2% to 92%, showing substantial interindividual variability. Stroke survivors with acute symptomatic status epilepticus (SeLECT2.0 7-13 points) had the highest risk (14%-92%). CONCLUSIONS: Personalised prognostic models, such as SeLECT2.0, may offer better guidance for poststroke driving decisions than generic SFIs. Our findings provide practical tools, including a smartphone-based or web-based application, to assess seizure risks and determine appropriate SFIs for safe driving.

Epilepsy Care in Latin America and the Caribbean: Overcoming Challenges and Embracing Opportunities.

The burden of epilepsy in the Latin America and the Caribbean (LAC) region causes a profound regional impact on the health care system and significantly contributes to the global epilepsy burden. As in many other resource-limited settings worldwide, health care professionals and patients with epilepsy in LAC countries face profound challenges due to a combination of factors, including high disease prevalence, stigmatization of epilepsy, disparities in access to care, limited resources, substantial treatment gaps, insufficient training opportunities for health care providers, and a diverse patient population with varying needs. This article presents an overview of the epidemiology of epilepsy and discusses the principal obstacles to epilepsy care and key contributors to the epilepsy diagnosis and treatment gap in the LAC region. We conclude by highlighting various initiatives across different LAC countries to improve epilepsy care in marginalized communities, listing strategies to mitigate treatment gaps and facilitate better health care access for patients with epilepsy by enhancing the epilepsy workforce.

Evaluation of epilepsy surgery scope and training in Latin America.

INTRODUCTION: To describe the variety of surgical epilepsy procedures offered in Latin America and characterize the training in surgical management for epilepsy and neurophysiology fellows. MATERIALS & METHODS: A 15-question survey was sent to Spanish-speaking epilepsy specialists in Latin America (members of the International Consortium in Epilepsy Surgery Education) to characterize their epilepsy surgery practices and formal training programs when present, including fellowship program characteristics, trainee involvement, and assessment of trainee performance. Epilepsy surgery procedures included resective/ablative interventions and neuromodulation therapies approved for drug-resistant epilepsy. Associations between categorical variables were evaluated using the Fisher Exact test. RESULTS: There were 42 responses from a total of 57 survey recipients (73% response rate). Most surgical programs performed either 1 to 10 procedures (36%) or 11 to 30 procedures (31%) per year. Most centers (88%) performed resective procedures, while none of the surveyed institutions performed laser ablations. Most of the centers performing intracranial EEG (88%) and advanced neuromodulation (93%) were in South America. Centers with formal fellowship training programs were more likely to perform intracranial EEG procedures compared to centers without fellows (92% vs 48%, respectively, OR = 12.2 [95% CI 1.45-583], p = 0.007). DISCUSSION: There is significant variability in surgical procedures performed across epilepsy centers in a Latin American educational consortium. Advanced surgical diagnostic procedures and interventions are performed in a fair number of surveyed institutions. Strategies to enhance access to epilepsy surgery procedures and facilitate formal training in surgical management are necessary.

Recomendaciones para estudios electroencefalográficos durante la pandemia covid-19 / Recommendations for electroencephalographic studies during the COVID-19 pandemic

RESUMEN Desde el inicio de la pandemia por covid-19 o SARS-CoV2 se han documentado múltiples manifestaciones neurológicas que abarcan desde encefalitis viral hasta enfermedad cerebrovascular aguda. Si bien el virus no implica un mayor riesgo para personas con diagnóstico de epilepsia en comparación con la población general, es pertinente establecer recomendaciones específicas para la realización de estudios electroencefalográficos en pacientes sin infección por covid-19, asi como para pacientes sospechosos, probables o confirmados para covid-19, teniendo en cuenta que los estudios electroencefalográicos son parte crucial de la evaluación de los pacientes con eventos paroxísticos. Basados en la evidencia publicada hasta el momento actual en la literatura médica y de acuerdo con las recomendaciones y publicaciones de la Sociedad Americana de Neurofisiología Clínica (ACNS), la Sociedad Americana de Neurodiagnóstico (ASET) y la Task Force ILAE-COVID de la Liga Internacional Contra la Epilepsia (ILAE), a continuación se exponen las consideraciones a tener en cuenta en cuanto a las indicaciones del estudio junto con un protocolo sugerido para la realización del mismo que abarca desde la duración del estudio hasta el número de electrodos sugerido, así como recomendaciones para el personal técnico y asistencial.

SUMMARY Since the onset of the COVID-19 pandemic, multiple neurological manifestations have been documented, ranging from viral encephalitis to acute stroke. Although the virus does not imply greater risk in people living with epilepsy in comparison with general population, it is relevant to establish specific recommendations for electroencephalographic studies in patients without COVID-19 infection, as well as in patients with suspected or confirmed COVID-19, taking into account that electroencephalographic studies are crucial for the evaluation of patients with paroxysmal events. Based on available evidence from the medical literature and in accordance with the recommendations and available resources of the American Clinical Neurophysiology Society (ACNS), the American Neurodiagnostic Society (ASET) and the ILAE-COVID Task Force from the International League Against Epilepsy (ILAE), below are the considerations to take into account regarding indications for the study along with a suggested protocol, which includes aspects such as the duration of the study, number of electrodes suggested and recommendations for technical and care staff.

Clinica de epilepsia / Epilepsy clinic

En forma general los pacientes con epilepsia se dividen en pacientes con crisis generalizadas y crisis parciales. Esta división ayuda en forma rápida a identificar los pacientes que van a requerir mas estudios diagnósticos, mas numero de consultas, posiblemente tratamiento con anticonvulsivantes diferentes a los de uso mas corriente y quienes van a ser refractarios al tratamiento médico
