Discussion of the Brazilian neurologists about sudden unexpected death in epilepsy.

OBJECTIVE: This study aimed to evaluate the concept of health professionals affiliated with the Brazilian League of Epilepsy on whether or not to inform patients about the risk factors related to the occurrence of sudden unexpected death in epilepsy. METHODS: A descriptive research of inquiry was conducted with direct survey on the Brazilian neurologist's view, regarding medical behavior in the health area to report or not about the risk of sudden unexpected death in epilepsy. Data collection consisted of a structured questionnaire available online. RESULTS: The study population consisted of a sample of 44 Brazilian League of Epilepsy members who answered the questionnaire, of which 25 (56.8%) were men and 19 (43.2%) were women. Among the analyzed questionnaires, 79.5% reported that they were aware of the risk factors for sudden unexpected death in epilepsy and 18.2% admitted not knowing the potential risk factors for sudden unexpected death in epilepsy. Notably, 59.1% of these professionals thought that an early discussion with the patient about sudden unexpected death in epilepsy must be considered. The majority (70%) felt that the neurologist should do this, and 22% believed that the subject should be discussed with psychologists. It was noted that 84.1% of respondents did not discuss or discussed only with some of their patients about the risk factors for sudden unexpected death in epilepsy. CONCLUSIONS: There is a need for encouraging early discussion of sudden unexpected death in epilepsy with epilepsy patients if the patient asks about the risks related to epilepsy and its treatment, when treatment adherence is low, in cases of intractable epilepsy with strong indication for surgical treatment, and when polytherapy is needed.

COVID-19 and epilepsy: How are people with epilepsy in Brazil?

PURPOSE: During COVID-19 pandemic the global population is facing an important psychosocial distress. The aim of this study was to evaluate how people with epilepsy (PWE) in Brazil is dealing with the pandemic, in relation to seizure frequency, access to antiseizure medicines (ASM), medical follow-up, and well-being. METHODS: An online questionnaire survey among PWE (group 1) and caregivers (group 2) was applied in the social networks of the Brazilian Association of Epilepsy, the official Brazilian chapter of the International Bureau for Epilepsy. The questionnaire was composed of 46 generic questions in four areas, namely, demographics and baseline clinical data as well as epilepsy and quality-of-life impact by COVID-19 pandemic based on the domains of the abbreviated World Health Organization Quality of Life (WHOQOL-BREF) instrument. RESULTS: The questionnaire was answered by 464 participants including 380 (81.9%) PWE (78.7% female; age 34.3 yrs.; ±9.76) and 84 (18.1%) caregivers (patients' age 14.1 yrs.; ±10.30). During the COVID-19 pandemic, 36.8% of PWE and 36.4% of caregivers reported difficulties in accessing the epilepsy healthcare provider, and visits occurred normally only in 29.7% of PWE and in 34.5% of the caregivers group. Telehealth was not provided for 66.6% of group 1 and for 58.5% of group 2. Lack of availability of ASM was reported by 21.9% of PWE and 28.0% of caregivers in public dispensing units and by 19.2% and 17.8%, respectively, in private pharmacies. Increase in seizures during pandemic was mentioned by 26.3% and 27.9% of groups 1 and 2, respectively. Patients who had increase in seizure frequency had more frequently reported problems with treatment and in quality-of-life concepts. Fear of having a more severe COVID-19 presentation because of epilepsy was reported by 74.5% of PWE and by 89.8% of caregivers. Dissatisfaction with current health status was reported by 36.7% and 38.1% in groups 1 and 2, respectively, and that the support from others has decreased (56.1% and 66.1%, in groups 1 and 2) during the pandemic. The factors with higher Odds Ratio of increase in seizure frequency during pandemic were age >41 yrs., treatment in public healthcare system, drug-resistant epilepsy, adversities in getting ASM in public dispensing units, difficulties with prescription renewals, current financial problems and belief that epilepsy or ASM are risk factors for contracting COVID-19. CONCLUSION: During COVID-19 pandemic in Brazil, PWE and caregivers reported increase in seizures in one-fourth of the patients and several difficulties, namely problems in accessing the healthcare system including ASM dispensation, telehealth, and fear of having a more severe COVID-19 because of epilepsy. There were also physical, psychological, and social concerns which affected quality-of-life-related aspects in this population. These facts may increase treatment gap in epilepsy in Brazil as well in other developing countries.

Two decades of research towards a potential first anti-epileptic drug.

The basic mechanisms by which brain insults, such as trauma, stroke or status epilepticus produce epilepsy are not completely understood, and effective preventive measures and treatment are still not available in the clinical setting. Over the last 2 decades we have conducted several studies with animal models of epilepsy (rodents and non-human primates) and demonstrated that drugs that modify neuronal plastic processes, such as anticholinergic agents (e.g., antimuscarinic compounds), if administered soon after brain injury and over a period of 10-20 days, have the potential to modify the natural course of post-traumatic epilepsy. To that end treatment with scopolamine showed promising results as a candidate agent in both the pilocarpine and kainate models. We then showed that biperiden, yet another cholinergic antagonist acting in the muscarinic receptor, that is widely used to treat Parkinson's disease, also decreased the incidence and intensity of spontaneous epileptic seizures, delaying their appearance in the pilocarpine model of epilepsy. In other words, biperiden showed to be a potential candidate to be further investigated as an antiepileptogenic agent. Accordingly, we tested the safety of biperiden in a small group of patients (as a small phase II safety assessment) and confirmed its safety in the context of traumatic brain injury (TBI). Now, we provide information on our ongoing project to evaluate the efficacy of biperiden in preventing the development of epilepsy in patients that suffered TBI, in a double blind, randomized, placebo-controlled trial.
