Dilek Turan F, İşler A, Duman Ö. Effect of virtual reality-based seizure management education program for parents (VR-ESMEPP) on seizure management: A randomized controlled trial. Epilepsy Behav 2024; 156:109824. [PMID: 38788661 DOI: 10.1016/j.yebeh.2024.109824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/29/2024] [Accepted: 05/01/2024] [Indexed: 05/26/2024]
Abstract
OBJECTIVE This study evaluated the efficacy of Virtual Reality-Based Seizure Management Education Program for Parents (VR-ESMEPP) that was designed to improve parents' knowledge-skill percentage about epileptic seizure, and motivation levels about educational material. METHODS The study was conducted at a university hospital's pediatric neurology clinic in Turkey and involved both a VR-trained group and a control group. The parents' knowledge-skill percentage about epileptic seizure, and motivation levels about educational material were assessed before, after, and at 15 days after participating in VR-ESMEPP. RESULTS The parents' knowledge-skill percentage about epileptic seizure increased in the group that participated in the VR-ESMEPP. There was no such increase in the control group. Examination of the scores of the Instructional Materials Motivation Survey (IMMS) for the parents showed that while there was a significant increase between the pre-test and post-test within the group that participated in the VR-ESMEPP, there was no significant difference in the scores of the control group. However, the high IMMS scores obtained by all parents indicate the motivating nature of the education material. SIGNIFICANCE The study established the efficacy of VR-ESMEPP and demonstrated its ability to enhance parents' knowledge-skill percentage about epileptic seizure. Despite the absence of a difference in motivation levels between the groups, the high scores obtained by all participants indicate that the program was indeed motivating.

Abstract
Background Epilepsy is a common neurological disorder that affects many people in Africa, yet the burden of the disease is often hidden. The management of epilepsy in Africa is often inadequate due to a lack of awareness and education, limited access to diagnostic tools and treatments, inadequate coordination of care, and the stigma associated with the condition. Method A comprehensive literature review was conducted to gather information on the epidemiology, diagnosis, management, and outcomes of epilepsy in Africa. The review included studies from peer-reviewed journals, government reports, and gray literature. Results The review revealed a high burden of epilepsy in Africa. The studies also showed a significant gap in the availability and accessibility of diagnostic tools, antiepileptic drugs, and specialized therapies such as physical, occupational, and speech therapy. Additionally, the review found that cultural beliefs and practices, socioeconomic factors such as poverty and lack of access to healthcare, and the stigma associated with the condition, also pose significant challenges to managing epilepsy in Africa. Conclusion The study highlights the urgent need for improved epilepsy management in Africa. Additionally, the study calls for further research on epilepsy in Africa and collaboration between all stakeholders to improve the management of epilepsy in Africa.

Abstract
Background Knowledge about the associated factors with epilepsy in the elderly in Iran is limited. Therefore, this study aimed to determine the prevalence of epilepsy and associated factors in Amirkola elderly patients. Methods This cross-sectional study is a part of a comprehensive and cohort research of "The Amirkola Health and Ageing Project". The Mini-mental State Examination was used for cognitive impairment, Geriatric Depression Scale for psychiatric diseases and the Physical Activity Scale for Elderly questionnaire for physical activity. Results The prevalence of epilepsy was 35 from 1482 participants (24/1000). The significant association between Parkinson's Disease (OR=6.25, 95%CI=1.35-28.4, P=0.001), falls (OR= 3.81, 95%CI=1.62-8.97, P=0.001), depression (P=0.001), hyperphosphatemia (P=0.039) and hypokalemia (P= 0.031) concluded with epilepsy. Past history of stroke (6 % versus 2%, OR= 2.8, 95%CI, 0.97-8.27, P=0.07), increased serum level of triglyceride (OR= 1.96, 95%CI= 0.99-3.88, P=0.06) and low-density lipoprotein (LDL) (P=0. 45) were seen in epileptic patients vs. non-epileptic patients. Conclusion Parkinson's disease, frequency of falls and depression were the associated factors in epileptic patients and a correlation between past history of stroke, increased serum level of triglyceride and LDL with epilepsy were seen. Associated factors required screening, diagnosis and treatment.

[PMID: 35986956 DOI: 10.1016/j.yebeh.2022.108875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 07/30/2022] [Accepted: 08/04/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Parents of children with epilepsy need support when managing epileptic seizures outside medical-care-center-settings. Previously developed training programs only provide information-based support. Therefore, within the scope of the VR-ESMEPP, a conceptual framework was developed in this study with the aim of developing parents' skills and motivation as well as providing them information regarding seizure management. METHODS The conceptual framework of the VR-ESMEPP was developed in four steps. In step 1, a scenario was developed wherein a pediatric patient with epilepsy is having a seizure. The selected seizure type was "Focal to bilateral tonic-clonic" seizure, which is the most common and most skill-intensive type of tonic-clonic-seizure. In step 2, data collection tools related to epileptic seizure management were developed for parents. These tools included Child and Parent Introductory Form, Parental Information Assessment Form for Epileptic Seizure Management, and Parental Skills Assessment Form for Epileptic Seizure Management. In step 3, the conceptual framework and data collection tools developed were confirmed by a group of 10 specialists consisting of physicians and pediatric nurses working in the field of pediatric neurology. In step 4, the epileptic-pediatric-patient-scenario and data collection tools confirmed by experts were programmed into an application by a software company and integrated into virtual reality headsets. RESULTS VR-ESMEPP with the conceptual framework described in the present study is a valid virtual reality-based program, which can be carried out under nurses' supervision and used to provide epilepsy-related education to parents. SIGNIFICANCE VR-ESMEPP helped parents increase their knowledge and skills of epileptic seizure.

Community-level prevalence of epilepsy and of neurocysticercosis among people with epilepsy in the Balaka district of Malawi: A cross-sectional study. PLoS Negl Trop Dis 2022; 16:e0010675. [PMID: 36108075 PMCID: PMC9477368 DOI: 10.1371/journal.pntd.0010675] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 07/19/2022] [Indexed: 11/18/2022] Open
Abstract
Background
Epilepsy and neurocysticercosis (NCC) prevalence estimates in sub-Saharan Africa are still scarce but show important variation due to the population studied and different screening and diagnosis strategies used. The aims of this study were to estimate the prevalence of epileptic seizures and epilepsy in the sampled population, and the proportion of NCC among people with epilepsy (PWE) in a large cross-sectional study in a rural district of southern Malawi.
Methods
We conducted a community-based door-to-door screening study for epileptic seizures in Balaka, Malawi between October and December 2012. Past epileptic seizures were reported through a 15-item questionnaire answered by at least one person per household generating five major criteria. People who screened positive were further examined by a neurologist to establish diagnosis. Patients diagnosed with epilepsy were examined and offered Taenia solium cyst antigen and antibody serological tests, and a CT scan for the diagnosis of NCC.
Results
In total, screening information on 69,595 individuals was obtained for lifetime occurrence of epileptic seizures. 3,100 (4.5%) participants screened positive, of whom 1,913 (62%) could be followed-up and underwent further assessment. Lifetime prevalence was 3.0% (95% Bayesian credible interval [CI] 2.8 to 3.1%) and 1.2% (95%BCI 0.9 to 1.6%) for epileptic seizures and epilepsy, respectively. NCC prevalence among PWE was estimated to be 4.4% (95%BCI 0.8 to 8.5%). A diagnosis of epilepsy was ultimately reached for 455 participants.
Conclusion
The results of this large community-based study contribute to the evaluation and understanding of the burden of epilepsy in the population and of NCC among PWE in sub-Saharan Africa.

Abstract
BACKGROUND Epilepsy is one of the most common neurological disorders worldwide. Yet, its treatment gap is large in some areas and especially in sub-Saharan Africa data on clinical, radiological and semiological characteristics, as well as on treatment of persons with epilepsy (PWE) are still scarce. METHODS We pooled data from four cross-sectional studies on epilepsy in eastern Africa. Two studies from Malawi and Uganda were community-based; two studies in Tanzania (urban Dar es Salaam and rural Haydom) were hospital-based. Clinical characteristics of PWE were assessed by the same questionnaire. Additionally, data on treatment were collected and computed tomography (CT) scans were performed. RESULTS Overall, 1179 PWE were included in our analysis (581 (49.3%) female, median age 22 years (IQR 15-32 years)). Up to 25% of the patients had focal onset seizures. Those showed a higher rate of remarkable CT scan findings, with especially post-ischaemic and neurocysticercosis-associated lesions, compared to PWE with generalized onset seizures (35.1% vs. 20%). The majority of the patients experienced tonic-clonic seizures (70-85%). Only 67-78% of PWE received anti-seizure medication (ASM) treatment in the community-based studies, mostly monotherapy with phenobarbital, phenytoin or carbamazepine. Yet, underdosage was frequent and a large proportion of PWE received alternative non-ASM treatment consisting of herbal treatment (up to 83%) and/or scarification (up to 20%). CONCLUSIONS Epilepsy is common in sub-Saharan Africa, often caused by neurocysticercosis or ischaemic strokes. PWE suffer from high seizure rates and subsequent injuries, as well as from socio-economic consequences due to insufficient ASM treatment. This pooled analysis illustrates the need for structural programmes for adequate identification, education, assessment and treatment of PWE in sub-Saharan Africa.

Abstract
Working in Africa provides neuroscientists with opportunities that are not available in other continents. Populations in this region exhibit the greatest genetic diversity; they live in ecosystems with diverse flora and fauna; and they face unique stresses to brain health, including child brain health and development, due to high levels of traumatic brain injury and diseases endemic to the region. However, the neuroscience community in Africa has yet to reach its full potential. In this article we report the outcomes from a series of meetings at which the African neuroscience community came together to identify barriers and opportunities, and to discuss ways forward. This exercise resulted in the identification of six domains of distinction in African neuroscience: the diverse DNA of African populations; diverse flora, fauna and ecosystems for comparative research; child brain health and development; the impact of climate change on mental and neurological health; access to clinical populations with important conditions less prevalent in the global North; and resourcefulness in the reuse and adaption of existing technologies and resources to answer new questions. The article also outlines plans to advance the field of neuroscience in Africa in order to unlock the potential of African neuroscientists to address regional and global mental health and neurological problems.

Epidemiology of Epilepsy in Low- and Middle-Income Countries: Experience of a Standardized Questionnaire over the Past Two Decades. Neuroepidemiology 2021; 55:369-380. [PMID: 34315167 DOI: 10.1159/000517065] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Accepted: 05/04/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Epilepsy affects >50 million people worldwide, with 80% of them living in low- and middle-income countries (LMICs). Studies with a standardized methodology are required to obtain comparable data on epilepsy and implement health policies in order to reduce the treatment gap and improve the diagnosis and management of epilepsy. In 2000, following the guidelines of the International League Against Epilepsy (ILAE), the "questionnaire for investigation of epilepsy in tropical countries" (IENT questionnaire) was developed to promote epidemiological surveys on epilepsy using a standard methodology. This study aims to describe how, when, where, and why the IENT questionnaire has been used through epidemiological studies on epilepsy over the last 2 decades and to acquire users' opinions about the tool. METHODS Studies that used the IENT questionnaire were searched through international and local bibliographic databases, including the gray literature. An online survey was carried out, including a snowball effect. Original research studies were included. Characteristics of the studies and populations and general information on the instrument and its use were collected. RESULTS Eighty-two documents were selected referring to 61 studies that were mostly carried out on the African continent (n = 54). Most of them aimed to determine the prevalence (n = 31) and associated factors (n = 28) of epilepsy in LMICs. Among the 61 studies, 35 were population-based, and 30 included both adults and children. A methodological heterogeneity was found between studies, and in cases where the IENT questionnaire alone did not ensure complete data collection, other tools were used concomitantly (n = 40). DISCUSSION/CONCLUSION Over the last 2 decades, the IENT questionnaire has been continuously used in different LMICs. This result favors its promotion and updating, with the inclusion of new topics related to epilepsy (e.g., comorbidities, quality of life, and stigma), current ILAE guidelines, and digital versions.

Abstract
Objectives Epileptic seizures and epilepsy in urban settings of low-income and middle-income countries (LMIC) are largely under-researched, but their prevalence is necessary for good healthcare planning. This study aimed to determine the lifetime prevalence of epileptic seizures and epilepsy in urban Dar es Salaam. Methods Nearly 50,000 people in former Kinondoni district, Dar es Salaam, were screened for epileptic seizures using a set of nine questions. Answers to these nine questions were categorized into generalized, focal, and unspecified seizures. Screening positivity rates were adjusted for questionnaire inaccuracy using two scenarios to analyse true epilepsy prevalences. Results Overall, 1085 (2.23%) people fulfilled the criteria for ever having had at least one type of epileptic seizure. Two-hundred-ninety-six (0.60%) people screened positive for generalized seizures, 986 (2.02%) for focal seizures, and 32 (0.07%) for unspecified seizures. Women more commonly screened positive than men (2.61% versus 1.72%, p < 0.001), particularly for focal seizures (p < 0.001). Adjusting for different degrees of accuracy of the screening questionnaire yielded true lifetime prevalences for epilepsy of any type between 1.59% and 2.41%. We furthermore observed a considerable variation of screening positivity rates between wards in Kinondoni district (p < 0.001). Conclusion The prevalence of epilepsy, based on a questionnaire survey in urban Tanzania, was higher than previously observed, probably due to the screening questionnaire, which contained questions specifically designed to identify focal seizures. Further studies on epileptic seizures/epilepsy are needed for urban settings in LMIC, preferably with an integrated follow-up of positive cases. Data on epilepsy in urban African populations are scarce Reliable prevalence estimates for epilepsy are important for healthcare planning but difficult to obtain Epilepsy screening tools need to be developed carefully in a participatory approach Focal and non-convulsive seizures are often overlooked in studies Epilepsy prevalence in urban Tanzania is similar to other parts of Africa

PLoS Negl Trop Dis 2021; 15:e0009234. [PMID: 33755677 PMCID: PMC8018642 DOI: 10.1371/journal.pntd.0009234] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 04/02/2021] [Accepted: 02/10/2021] [Indexed: 01/25/2023] Open
Abstract
Background The multi-host taeniosis/cysticercosis disease system is associated with significant neurological morbidity, as well as economic burden, globally. We investigated whether lower cost behavioral interventions are sufficient for local elimination of human cysticercosis in Boulkiemdé, Sanguié, and Nayala provinces of Burkina Faso. Methodology/Principal findings Province-specific data on human behaviors (i.e., latrine use and pork consumption) and serological prevalence of human and pig disease were used to inform a deterministic, compartmental model of the taeniosis/cysticercosis disease system. Parameters estimated via Bayesian melding provided posterior distributions for comparing transmission rates associated with human ingestion of Taenia solium cysticerci due to undercooking and human exposure to T. solium eggs in the environment. Reductions in transmission via these pathways were modeled to determine required effectiveness of a market-focused cooking behavior intervention and a community-led sanitation and hygiene program, independently and in combination, for eliminating human cysticercosis as a public health problem (<1 case per 1000 population). Transmission of cysticerci due to consumption of undercooked pork was found to vary significantly across transmission settings. In Sanguié, the rate of transmission due to undercooking was 6% higher than that in Boulkiemdé (95% CI: 1.03, 1.09; p-value < 0.001) and 35% lower than that in Nayala (95% CI: 0.64, 0.66; p-value < 0.001). We found that 67% and 62% reductions in undercooking of pork consumed in markets were associated with elimination of cysticercosis in Nayala and Sanguié, respectively. Elimination of active cysticercosis in Boulkiemdé required a 73% reduction. Less aggressive reductions of 25% to 30% in human exposure to Taenia solium eggs through sanitation and hygiene programs were associated with elimination in the provinces. Conclusions/Significance Despite heterogeneity in effectiveness due to local transmission dynamics and behaviors, education on the importance of proper cooking, in combination with community-led sanitation and hygiene efforts, has implications for reducing morbidity due to cysticercosis and neurocysticercosis. It is important to consider context-specific behaviors and transmission pathways when designing scalable and sustainable intervention strategies for neglected tropical diseases (NTDs). To reduce the morbidity and mortality associated with cysticercosis, suites of interventions have been recommended but are inconsistently implemented due to cost and feasibility-related constraints. This study investigated the potential of a cooking intervention to interrupt transmission via undercooked pork in marketplaces of Burkina Faso. The sensitivity of Taenia solium parasite to temperatures attainable via improved cooking strategies provides a low-cost, human-centered approach to prevent consumption of infected pork meals. By accounting for differential behavior and the relative role of this transmission route across three provinces, we show how the potential of cysticercosis elimination (as a public health problem) varies across behavior-focused interventions. Further investigation into intervention strategies against human and pig cysticercosis warrants data-driven analyses that account for local variation in transmission behaviors.

Translation and validation of an epilepsy-screening questionnaire in three Nigerian languages. Epilepsy Behav 2021; 114:107604. [PMID: 33268016 DOI: 10.1016/j.yebeh.2020.107604] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 10/22/2020] [Accepted: 10/24/2020] [Indexed: 01/30/2023]
Abstract
OBJECTIVE We describe the development, translation and validation of epilepsy-screening questionnaires in the three most popular Nigerian languages: Hausa, Igbo and Yoruba. METHODS A 9-item epilepsy-screening questionnaire was developed by modifying previously validated English language questionnaires. Separate multilingual experts forward- and back-translated them to the three target languages. Translations were discussed with fieldworkers and community members for ethnolinguistic acceptability and comprehension. We used an unmatched affected-case versus unaffected-control design for the pilot study. Cases were people with epilepsy attending the tertiary hospitals where these languages are spoken. The controls were relatives of cases or people attending for other medical conditions. An affirmative response to any of the nine questions amounted to a positive screen for epilepsy. RESULTS We recruited 153 (75 cases and 78 controls) people for the Hausa version, 106 (45 cases and 61 controls) for Igbo and 153 (66 cases and 87 controls) for the Yoruba. The sensitivity and specificity of the questionnaire were: Hausa (97.3% and 88.5%), Igbo (91.1% and 88.5%) and Yoruba (93.9% and 86.7%). The three versions reliably indicated epilepsy with positive predictive values of 85.9% (Hausa), 85.4% (Igbo) and 87.3% (Yoruba) and reliably excluded epilepsy with negative predictive values of 97.1% (Hausa), 93.1% (Igbo) and 95.1% (Yoruba). Positive likelihood ratios were all greater than one. CONCLUSIONS Validated epilepsy screening questionnaires are now available for the three languages to be used for community-based epilepsy survey in Nigeria. The translation and validation process are discussed to facilitate usage and development for other languages in sub-Saharan Africa.
