RESUMO
Ketogenic dietary therapies (KDTs) are a safe and effective treatment for pharmacoresistant epilepsy in children. There are four principal types of KDTs: the classic KD, the modified Atkins diet (MAD), the medium-chain triglyceride (MCT) diet, and the low glycemic index diet (LGID). The International Ketogenic Diet Study Group recommends managing KDTs in children with epilepsy. However, there are no guidelines that address the specific needs of the Brazilian population. Thus, the Brazilian Child Neurology Association elaborated on these recommendations with the goal of stimulating and expanding the use of the KD in Brazil.

RESUMO
CONTEXT: Epilepsy is a chronic neurological disorder that has social, cognitive, and psychological consequences to the patient. OBJECTIVE: The effects of the ketogenic diet (KD) in children and adults with pharmacoresistant epilepsy on cognitive function were evaluated in this systematic review. DATA SOURCES: The MEDLINE, Cochrane Library, Scopus, Web of Science, and LILACS databases were searched up to February 2021. STUDY SELECTION AND DATA EXTRACTION: From the 2973 records initially identified, 24 studies were included in the systematic review. These records were screened via PICO criteria, focusing on studies that evaluated the effects of KD on cognitive function of patients with pharmacoresistant epilepsy. RESULTS: Nineteen studies described improvements in cognitive function attributed to KD; improvements were not observed in 2 studies, but neither was aggravation. Contradictory results were reported in 3 studies, depending on the method used to assess cognition. At first glance, cognitive function appears to be associated with the number of seizures, diet effectiveness, amount of carbohydrate ingested, and antiseizure medication used. However, due to the diversity of methods used to assess cognitive function, especially self-perception of cognitive improvement by the patient, it was not possible to confirm this hypothesis. CONCLUSION: It was not possible to confirm if KD itself promotes improvements in cognitive function in patients with pharmacoresistant epilepsy. Certainly, more studies are needed with better methodological quality, larger and more homogeneous samples in relation to epileptic syndrome and clinical aspects of the disease, more rigid monitoring of adherence to the diet, and use of standardized tests for neuropsychological assessment. Systematic Review Registration: PROSPERO registration no. CRD42019129236.

BACKGROUND: Although ketogenic diet therapy (KDT) is a well-established, nonpharmacologic therapeutic option for patients with pharmacoresistant epilepsy, its availability is still not widespread. The COVID-19 pandemic may have further restricted the access of people with pharmacoresistant epilepsy (PWE) to KDT. Thus, we evaluated the experiences of Brazilian PWE and their caregivers during the first year of the pandemic. METHODS: An online self-assessed survey containing 25 questions was distributed via social media to be answered by PWE treated with KDT or their caregivers through Google Forms from June 2020 to January 2021. Mental health was assessed using the DASS and NDDI-E scales. RESULTS: Fifty adults (>18 yo), of whom 68% were caregivers, answered the survey. During the pandemic, 40% faced adversities in accessing their usual healthcare professionals and 38% in obtaining anti-seizure medication (ASM). Despite these issues, 66% of those on KDT could comply with their treatment. Those struggling to maintain KDT (34%) named these obstacles mainly: diet costs, social isolation, food availability, and carbohydrate craving due to anxiety or stress. An increase in seizure frequency was observed in 26% of participants, positively associated with difficulties in obtaining ASM [X2 (1, Nâ¯=â¯48)â¯=â¯6.55; pâ¯=â¯0.01], but not with KDT compliance issues. CONCLUSIONS: People with pharmacoresistant epilepsy and undergoing KDT, as well as their caregivers, faced additional challenges during the COVID-19 pandemic, not only difficulties in accessing healthcare and KDT maintenance but also on seizure control and mental health.

BACKGROUND: The coronavirus disease 2019 (COVID-19) outbreak impacted the lives of worldwide people with epilepsy (PWE) in various aspects, particularly in those countries most significantly affected by this pandemic, such as Brazil. We aimed to investigate the prevalence of depressive symptoms in PWE and their correlation with epilepsy features and access to treatment. METHODS: PWE were invited to answer a cross-sectional online-based survey to assess and rate depressive symptoms using the NDDI-E during the first year of the COVID-19 pandemic and its relation to multiple lifestyles epilepsy clinical aspects. RESULTS: A total of 490 PWE were recruited. The prevalence of depressive symptoms during the COVID-19 pandemic was 35.3% (cutoff scoreâ¯>â¯15 on NDDI-E). The factors associated with higher NDDI-E scores were: female sex, increased seizure frequency, barriers to access to their treating physician and antiseizure medication, and unemployment. Regarding the pandemic impact on PWE healthcare, 29.2% reported restricted access to their medication, 46.1% barriers to access their physicians, 94.2% had their consultations canceled due to the pandemic, and 28.4% had seizure worsening in this period. CONCLUSION: The COVID-19 pandemic affected PWE access to the healthcare system. Depressive symptoms were more severe in patients with higher seizure frequency who had difficulties obtaining proper medical care. The COVID-19 pandemic may impact the healthcare and mental wellbeing of patients with chronic diseases such as epilepsy. Nevertheless, prospective studies on epilepsy and COVID-19 are still lacking.

Background: Migraine and epilepsy are both common episodic disorders, typically precipitated or inhibited by some modulatory factors (MFs). Objective: To assess the self-perception of MFs in patients with migraine (PWM) compared to patients with epilepsy (PWE) with a standardized protocol in different countries. Methods: Transcultural multicenter comparative cross-sectional study. All consecutive patients who fulfilled the ICHD-3 criteria for migraine and ILAE's criteria for epilepsy, with at least 1 year of follow-up were interviewed with a semi-structured questionnaire on clinical and epidemiological data and were asked to identify all experienced MFs from a provided list. Results: A total of 608 individuals were surveyed at five university referral centers in Brazil, Guatemala, Lithuania and Turkey. Two hundred and nineteen (91.6%) PWM and 305 (82.7%) PWE identified attack precipitating factors (PFs; p < 0.001). The most frequent three PFs reported by epilepsy patients were: "lack of sleep" (56.6%), "emotional stress" (55.3%), "negative feelings" (53.9%), while among migraine patients "emotional stress" (81.6%), "lack of sleep" (77.8%), "negative feelings" (75.7%) were cited. Inhibitory factors (IFs) for the episodes were reported by 68 (28.5%) PWM and 116 (31.4%) PWE. "Darkness" was the most common one, described by 35.6% of PWM whereas "positive feelings" reported by 10.6% of PWE. Most MFs are concordant across the countries but some transcultural differences were noted. Conclusion: The MFs of migraine and epilepsy attacks and their varying frequencies according to different countries were investigated with the same standardized questionnaire, for the first time. MFs were recognized very often in both migraine and epilepsy cohorts, but in distinct disease-specific prevalence, being more frequent in migraine. Recognition of self-perceived MFs may be helpful for the management of both illnesses.
RESUMO
BACKGROUND: Anxiety and depressive symptoms are prevalent in patients with refractory mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE-HS) before and after anterior temporal lobectomy (ATL). AIMS: (1) To follow the levels of anxiety and depressive symptoms long-term after ATL among patients with refractory MTLE-HS; (2) To identify pre- and postsurgical variables associated with the levels of anxiety and depressive symptoms after surgery. METHODS: We compared the levels of anxiety and depressive symptoms determined by the Hospital Anxiety and Depression Scale (HADS) before and long after ATL (mean 104â¯months, range 70-130) in 41 consecutive patients refractory MTLE-HS. The last follow-up was between September 2018 and March 2020. We also determined pre- and postsurgical variables independently associated with the HADS scores after surgery. RESULTS: The scores of HADS and its subdomains related to anxiety and depression decreased significantly (pâ¯<â¯0.01) after ATL. After multiple linear regressions, the HADS-Anxiety scores before surgery (Bâ¯=â¯0.47, CI 95% 0.20 to 0.75, pâ¯=â¯0.001) and at follow-up after surgery (Bâ¯=â¯0.07, CI 0.00 to 0.14, pâ¯=â¯0.05) remain independently and positively associated with HADS-Anxiety scores after surgery. The HADS-Depression scores after surgery were independently positively associated with HADS-Depression scores before surgery (Bâ¯=â¯0.39, CI 95% 0.10 to 0.76, pâ¯=â¯0.01) and worse seizure control after surgery (Bâ¯=â¯1.55, CI 95% 0.23 to 2.87, pâ¯=â¯0.02). CONCLUSION: Anxiety and depressive symptoms in patients with MTLE-HS significantly improved after ATL. Presurgical levels of anxiety and depressive symptoms, respectively, were positively associated with the postsurgical levels of those symptoms. Length of follow-up is associated with anxiety, and worse seizure control is associated with depressive symptoms after ATL. The results have implications for the surgical management of MTLE-HS patients.

PURPOSE: To perform a cross-cultural adaptation of the Global Assessment of Severity of Epilepsy (GASE) and Global Assessment of Disability (GAD) scales to Brazilian Portuguese and compare patients' self-rated scores with their attending physicians' ratings. METHODS: We conducted an observational, multicentre, cross-sectional study. Patients followed up in five epilepsy centres in Brazil responded to GASE and GAD questionnaires and to the Hospital Anxiety and Depression Scale and the Adverse Events Profile, both previously validated in Brazil. GASE and GAD scales were also completed by 20 attending physicians providing care to these patients. RESULTS: A total of 138 patients were interviewed, with a mean age of 39.9 ± 13.81 years and a median of 11 (interquartile range, IQR = 7.5-12) years of education. Eighty-five (61.6%) patients were female. Most patients were diagnosed with focal epilepsy (82.6%). Only 5.8% and 3.6% of respondents reported having difficulty understanding the GASE and GAD, respectively. The patients scored a median of 3 (IQR = 2-5) on the self-perceived GASE and 4 (IQR = 2-6) on the GAD. Physician ratings were moderately to highly correlated with patients' self-perceived scores on the GASE and GAD. Linear regression analysis demonstrated that physicians' GASE and GAD scores predicted 37% and 20% of the patients' self-reported GASE and GAD variation, respectively. CONCLUSION: Brazilian Portuguese cross-cultural adaptation of the GASE and GAD was successful. These scales were found to be easy to use by patients and health professionals, and revealed the burden of epilepsy on patients' lives.

OBJECTIVES: To identify variables independently associated with a meaningful improvement in QOL long after surgical treatment of drug-resistant MTLE-HS patients. MATERIAL & METHODS: We prospectively evaluated 72 consecutive MTLE-HS surgically treated patients and analyzed pre and post-surgical variables independently associated with a meaningful improvement in QOL evaluated by the Quality of Life in Epilepsy-31 (QOLIE-31) overall score, and its domain scores determined at follow-up after 36 to 131 months (mean 93 months) after surgery. RESULTS: The mean overall QOLIE-31 score and its subdomain scores improved significantly after surgery (p < 0.01), and 55 patients (76.4%) had a meaningful QOL improvement. Being seizure-free (Engel IA) after surgery showed a non-significant association (OR 2.63, CI 95% 0.53 to 13.05, p = 0.23) and lower depressive symptoms a significant association (OR 4.15, CI 95% 1.19 to 14.53, p = 0.03) with meaningful improvement of QOL. CONCLUSIONS: Patients with MTLE-HS who underwent epilepsy surgery show a sustained, meaningful improvement in their QOL. Pre-surgical variables do not predict long-term QOL improvement after surgery. Lower levels of depressive symptoms at postoperative evaluation are associated with meaningful QOL improvement.

This study aimed to analyse the effect of neuropsychological activation methods on interictal epileptiform discharges, compared to standard activation methods, for both focal and generalized epilepsies. This was a multicentre, prospective study including 429 consecutive EEG recordings of individuals with confirmed or suspected diagnosis of epilepsy. Neuropsychological activation included reading aloud in foreign and native language, praxis and a letter cancelation task (each with a duration of three minutes). After counting interictal discharges in three-minute time windows, activation and inhibition were assessed for each procedure, accounting for spontaneous fluctuations (95% CI) and compared to the baseline condition with eyes closed. Differences between generalized and focal epilepsies were explored. Interictal epileptiform discharges were present in 59.4% of the recordings. Activation was seen during hyperventilation in 31%, in at least one neuropsychological activation method in 15.4%), during intermittent photic simulation in 13.1% and in the resting condition with eyes open in 9.9%. The most frequent single cognitive task eliciting activation was praxis (10.3%). Lasting activation responses were found in 18-25%. Significant inhibition was found in 88/98 patients with baseline interictal epileptiform discharges, and was not task-specific. Adding a brief neuropsychological activation protocol to the standard EEG slightly increased its sensitivity in patients with either focal or generalized epilepsy. However, in unselected epilepsy patients, this effect seems only exceptionally to result in ultimate diagnostic gain, compared to standard procedures. From a diagnostic perspective, cognitive tasks should be reserved for patients with a suspicion of cognitive reflex epilepsy/seizures and probably require longer exposure times. Further research is needed to explore potential therapeutic applications of the observed inhibition of interictal epileptiform discharges by cognitive tasks in some patients.

Objetivos: Avaliar o perfil clínico e epidemiológico dos pacientes parkinsonianos acompanhados no ambulatório de Distúrbios do Movimento do Hospital Governador Celso Ramos utilizando-se escaladas validadas. Métodos: Estudo longitudinal onde foram incluídos 167 pacientes consecutivos, em diferentes estágios da doença de Parkinson, atendidos no ambulatório de distúrbios do movimento do HGCR e reavaliados 20 pacientes em consulta, 5 anos após a primeira. Aplicou-se questionário e avaliou-se o primeiro sintoma motor cardinal entre as associações independentes e entre os escores de sintomas neurológicos motores avaliados através da escala UPDRS-MDS e Schwab and England Activities of Daily Living Scale. Resultados: Tremor foi o primeiro sintoma motor percebido mais frequentemente pelos pacientes (64,9%), dor foi a primeira queixa de 5,2% dos pacientes. A idade de início do primeiro sintoma foi inversamente proporcional à escolaridade. Quanto maior a pontuação nas escalar UPDRS-MDS III (p=0,004) e Schwab and England Activities of Daily Living Scale (p=0,001) maior a tendência a inatividade. Conclusão: A doença de Parkinson geralmente é percebida por seus sintomas motores clássicos, entretanto, uma série de sintomas não motores iniciam e acompanham a evolução da doença conforme mostra a piora do perfil ao longo de 5 anos.
Objectives: To evaluate symptoms, establish a profile for the Parkinsonian patient of HGCR's Movement Disorders's Service. Method: Longitudinal study. 167 consecutive patients, in different stages of Parkinson's disease, and treated at HGCR movement disorders service were inclueded. 20 of them were reevaluated after 5 yers. A questionnaire was administered and the first cardinal motor symptoms was evaluated and associated with independent associations and with the scores of neurological symptoms measured by UPDRS-MDS and through the Schwab and England Activities of Daily Living Scale. Results: Tremor was the first motor symptom perceived most frequently by patients (64.9%), pain was the first complaint of 5,2% of patients. The age of onset of the first symptom was inversely proportional to schooling. The higher the scores in the UPDRS-MDS-III scale (p=0,004) and the Schwab and England Activities of the Daily Living Scale (p = 0,001) the greater the tendency to inactivity. Conclusion: Parkinson's disease is usually noticed by its classic motor symptoms, however, a series of non-motor symptoms begin and accompany the disease's progression. This study evaluated the profile of the clinical and epidemiological patients attending our service and showed important clinical worsening in the evolution of 5 years of disease.
RESUMO
Pharmacoresistant epilepsy causes serious deleterious effects on the patient's health and quality of life. For this condition, a ketogenic diet (KD) is a treatment option. The KD is a general term for a set of diets that contain high amounts of fat and low content of carbohydrates. The most prominent KD treatments are classical KD (4:1 ratio of fat to carbohydrate), modified Atkins diet (2:1 to 1:1 ratio), medium-chain triglycerides KD (with medium-chain triglyceride as a part of the fat content), and low glycemic index KD (using low glycemic carbohydrates). KD has been widely prescribed for children with epilepsy but not for adult patients. One of the main concerns about adult use of KD is its cardiovascular risk associated with high-fat and cholesterol intake. Therefore, this narrative review provides comprehensive information of the current literature on the effects of KD on lipid profile, glycemic-control biomarkers, and other cardiometabolic risk factors in adult patients with pharmacoresistant epilepsy.

Hygienic and sanitary measures and social distancing policies implemented during the new coronavirus disease - COVID-19 - pandemic have altered the care and follow-up provided by healthcare professionals for patients with chronic diseases, including patients with epilepsy (PWEs). Telemedicine has become a solution for the healthcare of PWEs in many developed countries. In this short communication, we trace a particular perspective for the application of telemedicine for PWEs undergoing ketogenic diet (KD) treatment, considering the social and economic difficulties faced by healthcare teams in resource-poor countries, such as Brazil. During the pandemic, financial strain was the main impediment to following KD. The pandemic increased socioeconomic insecurity and access to KD-related products, as well as increasing anxiety in 71% of PWE, impacting their KD treatment follow-up. The challenges of telemedicine in Brazil include not only social and economic issues but also access to food, healthcare services, and education for the population, in addition to digital inclusion.

A ketogenic diet may be a therapeutic option for approximately one third of patients with epilepsy. These patients continue to have seizures despite suitable pharmacological treatment. Regardless of the diet's therapeutic potential regarding seizure control, adverse events may coexist. This requires constant monitoring of the patient as comorbidities may emerge. A prospective, nonrandomized and uncontrolled study was conducted to evaluate the effect of a ketogenic diet on cardiometabolic parameters (lipid profile, glycemic profile and body composition variables) and seizure control in adult patients with pharmacoresistant epilepsies. Patients followed the Modified Atkin's Diet (MAD), with a restriction of 20 g of carbohydrates per day, adequate protein amounts and fats ad libitum for 24 weeks. Fourteen eligible patients were enrolled in the study, however, only eight completed the treatment (four women with an average age of 33.5 ± 9.9 years and four men with an average age of 27.5 ± 9.0 years; p = 0.386). The median of focal impaired awareness seizures decreased from 9.0 (interquartile range [IQR] 4.0-28.0) seizures per month pre-diet to 4.0 (IQR 0.5-11.2) seizures per month in 12 weeks (p = 0.028), i.e. a 55.5% reduction. Total cholesterol (19,711 ± 1373 mg/dL to 28,427 ± 2545 mg/dL; p = 0.016), LDL (131.47 ± 1319 mg/dL to 194.85 ± 20.41 mg/dL; p = 0.037), and non-HDL (140.20 ± 13.04 mg/dL to 219.75 ± 28.53 mg/dL; p = 0.028) levels increased progressively over the intervention period, being significant at 24 weeks (n = 6). A significant reduction in blood glucose (89.70 ± 2.20 mg/dL to 82.62 ± 1.45 mg/dL at week 24, p < 0.001, n = 6), insulin (11.02 ± 1.78 µUI/mL to 6.20 ± 0.71 µUI/mL at week 12, p < 0.001, n = 6) and HOMA-IR index was observed (1.46 ± 0.29 to 0.91 ± 0.23 at week 24, p < 0.001, n = 5). The estimated cardiovascular risk after treatment was low for all patients (less than 10 %). A significant reduction in body weight (76.28 ± 6.62 kg to 69.14 ± 5.63 kg; p < 0.001), body mass index (26.41 ± 1.79 kg/m² to 24.05 ± 1.58 kg/m²; p = 0.001), and waist (87.40 ± 4.98 cm to 78.61 ± 3.94 cm; p < 0.001) and arm circumferences (32.12 ± 1.97 cm to 28.98 ± 1.30 cm; p < 0.001) was observed (n = 8), as well as reduction in fat mass (26.85 ± 3.15 g to 21.54 ± 2.64 g; p < 0.001) and fat free mass (48.01 ± 2.75 g to 46.60 ± 2.29 g; p < 0.001), n = 7. Adverse events were generally mild and treatable, with the following being the most common: headache (50 %), weakness (50 %), and gastrointestinal symptoms (37.5 %). Potentially atherogenic lipid profile changes were observed; however, improved glycemic control and reduced body weight and waist circumference demonstrated an improvement in cardiometabolic parameters. Framingham score and the QRISK3 showed lower cardiovascular disease risk for some of the patients. Our data suggests MAD could be an appropriate therapeutic choice for adults with pharmacoresistant epilepsies.

Introdução: A dieta cetogênica é um tratamento adjuvante para pacientes pediátricos com epilepsia e pode ser vantajoso para adultos. Objetivos: Fazer uma revisão bibliográfica narrativa de estudos envolvendo o tema Dieta Cetogênica (DC) no tratamento de pacientes com epilepsia adultos e disseminar o conhecimento deste tratamento. Métodos: Fez-se uma revisão de artigos publicados, sem limite de tempo, nas bases de dados eletrônicas Medical Literature Analysis and Retrieval System Online (Medline/PubMed), Google Acadêmico e The Scientific Electronic Library Online (SciELO). O primeiro passo foi a busca pelos descritores "ketogenic diet", "ketogenic diet for adults", "modified Atkins diet", "modified Atkins diet for adults", "medium chain tryglyceride diet", "low glycemic index treatment", "dieta cetogênica", "dieta cetogênica em adultos", "dieta de Atkins modificada" e "dieta de Atkins modificada em adultos". Resultados: Encontrou-se um total de 230 artigos por meio de busca nas bases de dados Medline/PubMed, SciELO e Google Acadêmico. De todos esses 231 artigos apenas 41 deles realmente abordavam o tema "dieta cetogênica em pacientes adultos com epilepsia" e estes foram lidos integralmente. Excluiu-se 189 artigos pois estes não abordavam o tema DC em adultos, abordavam a DC em outras doenças e não somente em epilepsia, utilizavam outra faixa etária que não somente adultos, estavam em outro idioma que não inglês ou português. Dos 41 artigos lidos na íntegra, 17 foram escolhidos para de fato compor o estudo. Conclusão: A dieta cetogênica é um tratamento eficaz e bem tolerado para pacientes adultos com epilepsia.
Introduction: The ketogenic diet is an adjunctive treatment for pediatric patients with epilepsy and may be of benefit to adults. Objectives: To perform a bibliographic review of studies involving the topic Ketogenic Diet in the treatment of patients with adult epilepsy and disseminate the knowledge of this treatment. Methods: A review of published articles was published, without time limit, in the electronic databases Medical Literature Analysis and Retrieval System Online (Medline / PubMed), Google Scholar and The Scientific Electronic Library Online (SciELO). The first step was to search for the descriptors "ketogenic diet", "ketogenic diet for adults", "modified Atkins diet", "modified Atkins diet for adults", "medium chain tryglyceride diet", "low glycemic index treatment" ketogenic diet in adults, modified Atkins diet, and modified Atkins diet in adults. Results: A total of 230 articles were found by searching the databases Medline / PubMed, SciELO and Google academic. Of all 231 articles only 41 of them actually addressed the topic "ketogenic diet in adult patients with epilepsy" and these were read in full. We excluded 189 articles because they did not address the topic DC in adults, they approached CD in other diseases and not only in epilepsy, used another age group that not only adults, were in a language other than English or Portuguese. Of the 41 articles read in their entirety, 17 were chosen to actually compose the study. Conclusion: The ketogenic diet is an effective and well tolerated treatment for adult patients with epilepsy.
RESUMO
OBJECTIVES: To investigate the significance of "subtherapeutic" vs "therapeutic" antiepileptic drug (AED) plasma levels with respect to treatment adherence. MATERIAL AND METHODS: One hundred and seventy patients with refractory temporal lobe epilepsy who underwent video-EEG monitoring in view of a surgical indication had their AEDs (carbamazepine, phenobarbital, phenytoin, and valproate) rapidly withdrawn following a standardized schedule. Plasma levels were measured at admission, and during the 2 days of drug withdrawal. Adherence and nonadherence were identified by the development of plasma levels from day 1 through day 3. Frequencies of an initial level below the reference range in both groups were compared. RESULTS: Adherence was found in 73.2% of cases, and nonadherence in 26.8%. Low levels were seen equally often (about 1/4 of cases) in adherent and nonadherent cases. The vast majority (73.7%) of low levels had another explanation than nonadherence (eg low-dose treatment or enzyme induction). Of 42 nonadherent cases, the vast majority of 76.2% had unsuspicious plasma levels at admission. CONCLUSIONS: "Subtherapeutic" AED plasma levels only rarely are caused by nonadherence whereas levels in the "therapeutic range" by no means prove that the patient is adherent to treatment. For meaningful interpretation, any level needs to be compared with other levels of the same patient. Our findings strongly emphasize the principle of individualized therapeutic AED monitoring as promoted by the Therapeutic Strategies Commission of the ILAE.

Precipitation and inhibition of seizures and epileptic discharges by sensory stimuli are receiving increasing attention because they provide insight into natural seizure generation in human epilepsies and can identify potential nonpharmacological therapies. We aimed to investigate modulation (provocation or inhibition) of epileptiform discharges (EDs) in mesial temporal lobe epilepsy (MTLE) versus idiopathic generalized epilepsy (IGE) by olfactory stimulation (OS) compared with standard provocation methods. The underlying hypothesis was that any response would be more likely to occur in MTLE, considering the anatomical connections of the temporal lobe to the olfactory system. This multicenter, international study recruited patients with either MTLE or IGE who were systematically compared for responses to OS using an EEG/video-EEG protocol including a 30-min baseline, twice 3-min olfactory stimulation with ylang-ylang, hyperventilation, and intermittent photic stimulation. The 95% confidence interval (CI) for the baseline EDs in each patient was calculated, and modulation was assumed when the number of EDs during any 3-min test period was outside this CI. A total of 134 subjects (55 with MTLE, 53 with IGE, and 26 healthy controls) were included. Epileptiform discharges were inhibited during OS in about half the patients with both MTLE and IGE, whereas following OS, provocation was seen in 29.1% of patients with MTLE and inhibition in 28.3% of patients with IGE. Olfactory stimulation was less provocative than standard activation methods. The frequent subclinical modulation of epileptic activity in both MTLE and IGE is in striking contrast with the rarity of reports of olfactory seizure precipitation and arrest. Inhibition during OS can be explained by nonspecific arousal. The delayed responses seem to be related to processing of olfactory stimuli in the temporal lobe, thalamus, and frontal cortex.

INTRODUCTION: Epilepsy is a prevalent neurological disorder that may cause school failure due to several factors such as seizure severity, lack of information about the condition and stigma. This study aimed to evaluate the degree of perceived stigma and knowledge towards epilepsy among education professionals, and additionally, provide them correct information about epilepsy to reduce stigma through a training course. METHODS: Social and demographic data, as well as the degree of stigma were obtained through the Stigma Scale of Epilepsy. To estimate the level of educational professionals' knowledge about epilepsy we used the Questionnaire about Epilepsy. Statistical analysis consisted of Pearson's or Spearman's correlation tests for numerical parametric or non-parametric variables were used to determine potential significant associations. A p <0.05 was considered significant. RESULTS: Two hundred and twenty-five education professionals were interviewed in three different cities in Southern Brazil. Approximately 65% of subjects would attempt to open the mouth of a student during a seizure and the stigma measured by Stigma Scale of Epilepsy before the course was 45.4±16.61. CONCLUSION: The data indicate that education professionals have partial knowledge about epilepsy and a short duration course would be able to improve it and reduce its stigma in this population.
INTRODUÇÃO: A epilepsia é uma doença neurológica prevalente que pode causar fracasso escolar devido a fatores como severidade das crises, pouca informação sobre a doença e estigma. Este estudo teve como objetivo avaliar a percepção do estigma e conhecimento em epilepsia pelos profissionais de educação, fornecer informações corretas sobre epilepsia e reduzir o estigma através de um curso de curta duração. METODOLOGIA: Os dados sociodemográficos e o grau de estigma foram obtidos através da Escala de Estigma em Epilepsia. O grau de conhecimento em epilepsia foi obtido através da adaptação do Questionário Sobre Epilepsia. O teste de correlação de Pearson ou Spearman foi utilizado para análise das variáveis numéricas contínuas paramétricas ou não-paramétricas. O valor de p<0,05 foi considerado significante. RESULTADOS: Duzentos e vinte e cinco sujeitos foram entrevistados em três cidades do Sul do Brasil. Aproximadamente 65% deles abriria a boca do estudante durante uma crise e o grau do estigma avaliado com a Escala de Estigma em Epilepsia pré-curso foi de 45.4±16.61. CONCLUSÃO: Os dados indicam que os profissionais da educação têm um conhecimento pacial sobre epilepsia e que um curso de curta duração foi capaz de aumentar o conhecimento e reduzir o estigma na população estudada.

Epileptic seizures may be triggered by both nonspecific facilitating factors and specific reflex epileptic mechanisms. These consist of sensory or cognitive inputs activating neural networks that, due to some functional instability, may respond with an epileptic discharge. The aim of this study was to determine the prevalence and nature of self-perceived seizure-inducing and -inhibiting factors in patients with mesial temporal lobe epilepsy (MTLE) followed from March 3rd to December 8th, 2009 at the Centro de Epilepsia de Santa Catarina Outpatient Clinic of the Hospital Governador Celso Ramos in Florianópolis, Brazil and their relation to demographics, epilepsy-related variables and anxiety level. Of the 71 patients, 60 (84.5%) patients identified at least one seizure trigger, and 36 (50.7%) patients identified inhibiting factors. In order of frequency, the most freely recalled precipitants were nervousness (58.8%), worrying (21.6%) and menstruation (19.6%), while the precipitants that were most frequently identified from a list were worrying (73.2%), anxiety (66.2%) and anger (53.5%). Knowledge of precipitant factors may have implications on the treatment and seizure control of patients.

Epilepsy may restrict the patient's daily life. It causes lower quality of life and increased risk for work-related accidents (WRA). The aim of this study is to analyze the implantation of the Epidemiologic and Technical Security System Nexus (ETSSN) and WRA patterns among patients with epilepsy. Data regarding WRA, between 1999 and 2008, on the historical database of WRA Infolog Statistical Yearbook from Brazilian Ministry of Social Security were reviewed. There was a significant increase of reported cases during the ten year period, mainly after the establishment of the ETSSN. The increased granted benefits evidenced the epidemiologic association between epilepsy and WRA. ETSSN possibly raised the registration of occupational accidents and granted benefits. However, the real number of WRA may remain underestimated due to informal economy and house workers' accidents which are usually not included in the official statistics in Brazil.
