RESUMEN
PURPOSE: We conducted an observational study to investigate the opinions of neurologists and psychiatrists all around the world who are taking care of patients with seizures [epilepsy and functional seizures (FS)]. METHODS: Practicing neurologists and psychiatrists from around the world were invited to participate in an online survey. On 29th September 2022, an e-mail including a questionnaire was sent to the members of the International Research in Epilepsy (IR-Epil) Consortium. The study was closed on 1st March 2023. The survey, conducted in English, included questions about physicians' opinions about FS and anonymously collected data. RESULTS: In total, 1003 physicians from different regions of the world participated in the study. Both neurologists and psychiatrists identified "seizures" as their preferred term. Overall, the most preferred modifiers for "seizures" were "psychogenic" followed by "functional" by both groups. Most participants (57.9%) considered FS more difficult to treat compared to epilepsy. Both psychological and biological problems were considered as the underlying cause of FS by 61% of the respondents. Psychotherapy was considered the first treatment option for patients with FS (79.9%). CONCLUSION: Our study represents the first large-scale attempt of investigating physicians attitudes and opinions about a condition that is both frequent and clinically important. It shows that there is a broad spectrum of terms used by physicians to refer to FS. It also suggests that the biopsychosocial model has gained its status as a widely used framework to interpret and inform clinical practice on the management of patients.

PURPOSE: To investigate the opinions of physicians about brain surgery for drug-resistant epilepsy worldwide. METHODS: Practicing neurologists, psychiatrists, and neurosurgeons from around the world were invited to participate in an online survey. The survey anonymously collected data about demographics, years in clinical practice, discipline, nation, work setting, and answers to the questions about beliefs and attitudes about brain surgery for drug-resistant epilepsy. RESULTS: In total, 1410 physicians from 20 countries and different world regions participated. The propensity to discuss brain surgery with patients, who have drug-resistant seizures, was higher among men (versus women) [Odds Ratio (OR) 1.67, 95% CI 1.20-2.31; p = 0.002]. In comparison to neurologists, psychiatrists were less likely (OR 0.28, 95% CI 0.17-0.47; p < 0.001) and neurosurgeons were more likely (OR 2.00, 95% CI 1.08-3.72; p = 0.028) to discuss about it. Survey participants working in Africa, Asia, the Middle East, and the Former Union of Soviet Socialist Republics showed a lower propensity to discuss epilepsy surgery with patients. CONCLUSION: This study showed that on an international level, there is still a knowledge gap concerning epilepsy surgery and much needs to be done to identify and overcome barriers to epilepsy surgery for patients with drug-resistant seizures worldwide.

The importance of engaging the next generation in broad ranging initiatives cannot be over emphasized. This is reflected by a proliferation of publications related to next-generation, training, and healthcare professionals or scientists, with almost 2000 articles published in the last 30 years, showing a marked increase in the previous two decades. Several multilateral organizations, such as the United Nations, UNESCO and the World Health Organization, have recognized the importance of engaging youth in the global agenda. Accordingly, in 2017 The International League Against Epilepsy (ILAE) created organizational entities focused on epilepsy and the next generation of epilepsy professionals. At the core of these is the ILAE Young Epilepsy Section (YES). Its mission is to create a new generation of epilepsy experts poised to discover and deliver state-of-the-art care for people with epilepsy well into the future, with several initiatives worldwide, including education, research collaborations, and advocacy tasks, among others. The Latin American Summer School on Epilepsy, which turns 15 in 2021, has been a steady source of early career epilepsy professional participating in YES, who are moving forward the epilepsy agenda in Latin America.

PURPOSE: To investigate the opinions of physicians on the use of complementary and alternative medicine (CAM) in patients with epilepsy (PWE) worldwide. METHODS: Online survey addressed to neurologists and psychiatrists from different countries. RESULTS: Totally, 1112 physicians from 25 countries (different world region: Europe, North America, South America, Middle-East, Africa, Former Soviet Union Republics) participated; 804 (72.3%) believed that CAM might be helpful in PWE. The most commonly endorsed CAM included meditation (41%) and yoga (39%). Female sex, psychiatry specialization, and working in North and South America were associated with the belief that CAM is helpful in PWE. Two-hundred and forty five out of 1098 participants (22.3%) used/prescribed CAM to PWE; among them, 174 (71%) people perceived CAM to be less effective and 114 (46.5%) people found CAM to be safer than conventional antiseizure medications (ASMs). The most common reasons to prescribe CAM for PWE were: to satisfy the patient (49.9%), dissatisfaction with the efficacy (35.6%), and dissatisfaction with the adverse effects (31.2%) of conventional therapies. CONCLUSION: Although the evidence supporting the use of CAM for the treatment of epilepsy is extremely sparse, most physicians worldwide believe that it could be integrated with the use of conventional ASMs, at least in some patients. High-quality controlled trials are warranted to provide robust evidence on the usefulness of CAM options in PWE.

OBJECTIVE: Psychogenic nonepileptic seizures (PNES) are one of the most common differential diagnoses of epilepsy. This study provides an overview of diagnostic and treatment services for patients with PNES across Latin America. METHODS: In 2017-2018, clinicians practicing in Latin America with responsibilities for patients with PNES were contacted to respond to a survey regarding the management of this disorder developed by the International League Against Epilepsy (ILAE) PNES Task Force. RESULTS: Three hundred and sixty responses from 17 Latin American countries were analyzed. Most respondents were neurologists (81%) under 40â¯years of age (61%). Fifty-seven percent of professionals stated that they personally diagnose PNES, but only 33% stated that they provide follow-up, and only 20% that they recommend treatment. Many participants (54%) characterized themselves as either unfamiliar with the diagnosis or inexperienced in arranging treatment. Most respondents reported having access to brain magnetic resonance imaging (MRI; 88%) and routine electroencephalogram (EEG; 71%), 64% have the access to video-EEG longer than 8â¯h, and 54% of professionals performed video-EEG to confirm PNES diagnoses. Although cognitive-behavioral therapy was recognized as the treatment of choice (by 82% of respondents), there was little access to it (60%). In contrast, a high proportion of respondents reported using antidepressant (67%), antiseizure (57%), and antipsychotic medications (54%) as treatments for PNES. SIGNIFICANCE: This study reveals several deficiencies in the diagnosis and treatment of patients with PNES in Latin America. The barriers are reinforced by lack of knowledge among the specialists and poor healthcare system support. There is inadequate access to prolonged video-EEG and psychotherapy. An inappropriate use of antiseizure medicines seems commonplace, and there are low follow-up rates by neurologists after the diagnosis. Multidisciplinary guidelines are required to improve the approach of patients with PNES.

OBJECTIVES: In this international study, we aimed to investigate the opinions of physicians dealing with patients with functional seizures (FS) worldwide on working restrictions and disability benefits eligibility. METHODS: International online survey of neurologists/mental health professionals from Argentina, Venezuela, Colombia, Italy, France, Iran, Iraq, United Arab Emirates (UAE), Qatar, Saudi Arabia, Georgia, and Russia. RESULTS: Six hundred and twenty-seven physicians from 12 countries participated in the study. Working as a neurologist was a predictor to think that patients with FS should not be counseled to avoid performing all jobs or professions as long as they have active disease (OR: 0.46; 95% CI: 0.30 to 0.68; pâ¯<â¯0.001). Having managed more than 200 patients was associated with the opinion that patients should not be counseled to avoid performing any type of work (OR: 2.17; 95% CI: 1.02 to 4.59; pâ¯=â¯0.043). Working as a psychiatrist/psychologist was associated with the idea that patients with FS should be qualified for disability benefits (OR: 1.97; 95% CI: 1.21-3.21; pâ¯=â¯0.006), and receive these benefits lifelong (OR: 0.43; 95% CI: 0.22-0.84; pâ¯=â¯0.014). CONCLUSION: Neurologists and mental health professionals have different attitudes and opinions toward working restrictions and disability benefits for patients with FS. Further studies should investigate the reasons for these differences, and propose solutions to avoid discrimination and unequal access to employment and disability benefits.

OBJECTIVE: Clinical genetic sequencing is frequently utilized to diagnose individuals with neurodevelopmental disorders (NDDs). Here we perform a meta-analysis and systematic review of the success rate (diagnostic yield) of clinical sequencing through next-generation sequencing (NGS) across NDDs. We compare the genetic testing yield across NDD subtypes and sequencing technology. METHODS: We performed a systematic review of the PubMed literature until May 2020. We included clinical sequencing studies that utilized NGS in individuals with epilepsy, autism spectrum disorder (ASD), or intellectual disability (ID). Data were extracted, reviewed, and categorized according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two investigators performed clinical evaluation and grouping following the International League Against Epilepsy (ILAE) guidelines. Pooled rates of the diagnostic yield and 95% confidence intervals were estimated with a random-effects model. RESULTS: We identified 103 studies (epilepsy, N = 72; ASD, N = 14; ID, N = 21) across 32,331 individuals. Targeted gene panel sequencing was used in 73, and exome sequencing in 36 cohorts. Given highly selected patient cohorts, the diagnostic yield was 17.1% for ASD, 24% for epilepsy, and 28.2% for ID (23.7% overall). The highest diagnostic yield for epilepsy subtypes was observed in individuals with ID (27.9%) and early onset seizures (36.8%). The diagnostic yield for exome sequencing was higher than for panel sequencing, even though not statistically significant (27.2% vs 22.6%, P = .071). We observed that clinical sequencing studies are performed predominantly in countries with a high Inequality-adjusted Human Development Index (IHDI) (countries with sequencing studies: IHDI median = 0.84, interquartile range [IQR] = 0.09 vs countries without sequencing studies: IHDI median = 0.56, IQR = 0.3). No studies from Africa, India, or Latin America were identified, indicating potential barriers to genetic testing. SIGNIFICANCE: This meta-analysis and systematic review provides a comprehensive overview of clinical sequencing studies of NDDs and will help guide policymaking and steer decision-making in patient management.

Psychogenic nonepileptic seizures (PNES) are episodes of seizure-like symptoms that are not associated with epileptiform discharges on electroencephalogram (EEG). They can be remarkably difficult to distinguish from epileptic seizures: both may involve alterations in mental status and behavior, sensory or perceptual disturbances, as well as simple or complex motor patterns. Pictorial expressions of PNES have always attracted attention from the lay public and medical practitioners alike, by showing the rich variety of semiologies seen in the condition and its differences with epileptic seizures. In this article, we present two new contemporary artistic descriptions by the Canadian artist Iris Hauser about PNES. The depictions highlight key signs seen in PNES such as "eyes closed during events", "the hyperextension of the back and limbs", and the "claw-like finger posturing". We believe that the drawings can provide a valuable educational component in the initial assessment of patients suspected of having PNES as a training tool to identify and refer patients for more advanced testing.

Antiepileptic drug side effects are frequent, 42% of them corresponding to cosmetic changes. The most frequent effects are weight gain, gingival hyperplasia, and hair loss. Hair changes in texture or colour are rarely reported in the literature. We present a case of hair curling after the introduction of perampanel. A 13-year-old girl with genetically confirmed Pitt-Hopkins syndrome with uncontrolled seizures, while on treatment with levetiracetam and valproic acid, was started on perampanel, reaching seizure control. After a few weeks of the introduction of the new antiepileptic drug, she developed hair curling. Hair curling is a rare cosmetic side effect, reported mainly in patients under valproic acid treatment. Perampanel is a recently introduced pharmaceutical molecule with no prior reports of hair changes as a side effect. There is no clear explanation for this side effect, but it should be discussed with patients taking valproate whenever perampanel is added to the treatment.

OBJECTIVE: Forced normalization (FN) is an intriguing phenomenon characterized by the emergence of psychiatric disturbances following the establishment of seizure control or reduction in the epileptic activity in a patient with previous uncontrolled epilepsy. We aim to describe the clinical characteristics of the condition. METHODS: We conducted a systematic review on MEDLINE, EMBASE, Cochrane, and Scielo from January 1953 to January 2018. Clinical, electrographic, and imaging data were gathered. We considered all outcomes in children and adults. We performed no meta-analyses due to the limited available data. RESULTS: Of 2606 abstracts identified, 36 fulfilled the FN diagnostic criteria; 193 FN episodes were evaluated and 77 of them were analyzed extensively. Sixty percent of cases were female. Mean age ± standard deviation (SD) was 28.3 ± 14.2 years. The majority of patients had focal (80%) symptomatic (44%) epilepsy. Most patients reported a high ictal frequency (58%) and were on polytherapy (51%). Patients presented psychosis (86.4%), mood disorders (25.8%), and dissociation (4.5%) as the main manifestations. In the psychosis group, persecutory (52.6%) and reference (47.3%) delusions were frequent. FN was provoked by an antiepileptic drug (AED) (48.5%) mainly levetiracetam, epilepsy surgery (31.8%), or vagus nerve stimulation (13.6%). Treatment was homogeneous including anticonvulsant withdrawal (47%) or taper (25%); antipsychotics were initiated in the majority of cases (73%). Psychiatric symptoms were partially controlled in 35%, with complete resolution of symptoms in the remaining 65% of cases. The majority of patients (87%) with AED trigger and withdrawal presented complete resolution of symptoms in comparison to 28.5% of patients triggered by surgery. SIGNIFICANCE: Forced normalization is an entity whose pathophysiology remains uncertain. Antipsychotic drug use does not predict complete resolution of psychiatric symptoms in comparison with AED withdrawal. Although there is a positive response to treatment in patients with FN triggered by drugs, the prognosis is obscure in patients with surgery triggered FN.

Resumen El síndrome de piernas inquietas (SPI) es un trastorno sensitivo y motor en el que el paciente refiere un deseo incontenible de mover las extremidades, que puede estar acompañado por una sensación desagradable, mal definida, y hasta en el 50 % de los casos con dolor, difícil de ubicar en un punto específico, y que inicialmente se manifiesta en las piernas. Se presenta principalmente en las noches impidiendo el sueño y subsecuentemente afectando la calidad de vida del paciente. Clásicamente se divide en síndrome de piernas inquietas primario y secundario, por la presencia o no de enfermedades concomitantes relacionadas con el tratamiento y pronóstico del SPI. Esta enfermedad tiene una incidencia en la población general de 9 a 22 pacientes por cada 1.000 personas al año (equivalente a 1,7 % por año); con una prevalencia de 5-13 % de la población general. El diagnóstico del SPI se realiza mediante el uso de los criterios establecidos por el Grupo Internacional de Estudio de SPI, divididos en esenciales y de soporte. Su tratamiento tiene como piedra angular a los agonistas dopaminérgicos, y otros medicamentos como el gabapentin enacarbil que han ganado terreno en los últimos años. La importancia del conocimiento de la enfermedad radica en el impacto negativo que ejerce sobre la calidad de vida de los pacientes afectados en general, y el aumento de la mortalidad en los pacientes con comorbilidad de enfermedad renal terminal en particular. Su diagnóstico es clínico y debe buscarse como causa de insomnio.
Summary Restless leg syndrome (RLS) is a sensory motor disorder in which the patient referred an urge to move the limbs, which may be accompanied by an ill-defined sense, and up to 50% of cases with pain, difficult to locate, and initially manifests in the legs. It occurs mostly at night, disrupting sleep and subsequently affecting the quality of life of patients. It is classically divided into primary and secondary restless legs syndrome, based on the presence or absence of comorbidities related to the treatment and prognosis of RLS. This disease has an incidence in the general population of 9-22 patients per 1,000 people per year (equivalent to 1.7% per year); with a prevalence of 5-13% of the general population. The diagnosis of RLS is done by using the criteria established by the International RLS study group, divided into essential and supportive. The treatment's cornerstone are dopamine agonists, and other drugs, such as gabapentin enacarbil that have been used more recently. The importance of the disease lies in the negative impact it has on the quality of life of affected patients in general, and increased mortality in patients with end stage renal disease comorbidity in particular.
