Epilepsy in mainstream and special educational primary school settings

Chronic diseases and illness in schools: Teachers' confidence in helping students with intellectual disabilities

Background

With movement to educate students with intellectual disabilities in special and mainstream schools, a considerable number of students with intellectual disabilities have common chronic diseases such as epilepsy and diabetes. In addition, these students may also face common illnesses, which occur in all students, such as fevers and headaches. Teachers are responsible for their students and provide first aid when needed. Therefore, this study aimed to determine whether teachers are confident in their ability to provide help when symptoms related to chronic diseases and illnesses occur.

Methods

In this cross-sectional study, questionnaires were sent to 300 male and female teachers of students with intellectual disabilities in Riyadh, Saudi Arabia.

Results

The findings illustrate that, in general, teachers have little confidence in helping students with chronic diseases and illnesses. Although the teachers felt that they were less confident in dealing with some symptoms of illnesses and chronic diseases, there were some symptoms that they showed either strong or low confidence in dealing with.

Conclusion

The recommendations include increasing teachers' confidence in providing first aid.

Epilepsy life skill education guidelines for primary school teachers and learners in Limpopo and Mpumalanga Provinces, South Africa: Multiphase mixed methods protocol

Epilepsy is a disorder in which nerve cell activity in the brain is disturbed, causing seizures. It may result from a genetic condition and occurs mainly in children, especially at a primary level. Most people living with Epilepsy suffer from stigma and discrimination because of a lack of knowledge regarding Epilepsy. This study aims to develop life skills education guidelines for primary school learners of Limpopo and Mpumalanga provinces to educate learners about Epilepsy, thus decreasing stigma and discrimination. A multimethod research approach will be used in this study to fulfil its purpose. Both stages 1 and 2 of the empirical phase (phase 1) will employ an exploratory-descriptive study design focusing on the primary school teachers, life skills educational advisors and learners to obtain their perceptions or views regarding the need to include Epilepsy in life skills education. Data will be collected using individual interviews for life skill educational advisors and focus group discussions for teachers and learners at the sampled primary schools in Limpopo and Mpumalanga provinces. Phase two will conceptualise the phase 1 findings into the conceptual framework, and phase 3 will develop and validate the life skills guideline. This study will adhere to both internal and external ethical considerations. Recommendations will be made based on the findings of the study.

Children and adolescents with epilepsy in rehabilitation centers: A French prospective transversal study

INTRODUCTION

The reason why some children and adolescent with epilepsy (CAWE) still challenge the "inclusive" educative policy needs to be explored.

METHODS/PATIENTS

We conducted a transversal study in French medical, social, and educative rehab centers (MSERCs) dedicated to CAWE to describe the profile of 263 centers-involved (CI)-CAWE. Centers-involved CAWE were prospectively followed from September 2012 to August 2013. Medical, social, and educative rehab centers were dichotomized according to their care-provider agreement (i.e., CAWE of "moderate" (M) vs. "severe" (S) conditions). Clinical factors known to impact clinical outcome and quality of life (QoL) in epilepsy and four disabling conditions at risk to impact school life (i.e., cognitive and psychiatric/behavioral disorders, risk of physical hazards (i.e., refractory seizures with unpredictable loss of tone and/or awareness), and one or more seizure/week) were evaluated. The electronic chart of the French collaborative database (namely GRENAT) was used for data collection allowing comparison with the profile of 731 "normally integrated and schooled" (NIS)-CAWE extracted from GRENAT and matching for generation (i.e., born between 1988 and 2006).

RESULTS

Centers-involved CAWE's profile was found, after adjustment, to be associated with clinical factors and disabling conditions reflecting the poorest clinical outcome and health-related quality of life (HR-QoL) (all p < 0.001). A cutoff of two disabilities/child highly discriminated NIS-CAWE vs. CI-CAWE. Centers-involved CAWE of S-MSERCs were the most severe (all p < 0.001), and the type of cognitive disability (i.e., intellectual disability (ID) vs. specific learning disorders (SLD)) highly paralleled the types of MSERCs (S vs. M). Using a parent-informant questionnaire, the number of disabilities/child was found to correlate with both the evaluation of the impact of epilepsy (r = 0.47, p < 0.001) and the HR-QoL (r = 0.37, p < 0.001). A satisfactory social life was reported (83.8%) even after S vs. M dichotomization (77.2% vs. 94.7%; p < 0.001).

CONCLUSION

Multiple disabilities rather than epilepsy per se challenge the inclusive educative policy. Evaluation of disabilities could be the missing bridge to optimize this policy and understand its limits.

Classification and management of epilepsy and epileptic syndromes in a cohort of 202 school children- a 2 year follow up study- Sudan

BACKGROUND

In this paper, seizure types, and epilepsy syndromes are elucidated as per ILAE (2010) classification. A brief outline of the antiepileptic drug regimens used and the outcome of seizure control in a two -year period is presented. The applicability of the ILAE classification in resource limited countries has been revisited.

METHODS

This is a descriptive prospective study, in which 202 patients were enrolled. The Cohort group was seen and evaluated by a pediatric neurologist at the Pediatric neurology Outpatients Department (OPD). Epilepsy was classified using the International League Against Epilepsy (ILAE) classification (2005-2009) report. All patients had an Electroencephalogram (EEG) at the start of the study, and this was repeated as deemed appropriate. Brain imaging (MRI) was done to patients when indicated. Treatment decisions were made by pediatric neurologists. Outcomes were categorized into four groups: fully recovered, well controlled, partially controlled and uncontrolled.

RESULTS

The mean age is 10.5 + 2.7 years. Male to female ratio was 1.7: 1. Thirty five (17.3%) patients had generalized onset seizures, 46(22.8%) had focal onset seizures, 104(51.5%) had a specific epilepsy syndrome, and 17(8.4%) patients were unclassified. 170 (84.2%) patients were on mono-therapy on their initial visit, 30(14.8%) were on two Antiepileptic Drugs (AEDs) while two (1.0%) patients were on poly-therapy. After 2 years; 155(76.7%) patients were on mono-therapy, 36(17.8%) on two AEDs while ten were (4.0%) on polytherapy. One eighty (88.2%) patients were controlled. Fifteen (7.4%) of them were off medication after being seizure free for 2 years. Twenty (9.8%) have partial control, while two (1.0%) patients were uncontrolled. Patients with focal epilepsy, those on polytherapy and those with abnormal imaging had poor prognosis.

CONCLUSIONS

The ILAE classification can be used in resource limited countries. Childhood epilepsies have a good prognosis provided they are well classified and treated.

Prevalence of epilepsy in 74,949 school children in Khartoum State, Sudan

BACKGROUND

Data on childhood epilepsy in Sudan are scarce and the only published study on its prevalence was published in 1983. This study aimed to determine the current prevalence of epilepsy in school children in Khartoum State.

METHODS

This is an analytical population-based, cross-sectional study conducted in Khartoum State, Sudan. The study included students in the basic (primary) schools aged 6-14 years. Simple random sampling was used to draw a cluster of four of the seven localities comprising Khartoum State. The sample frame consisted of 1609 public schools (808,624 pupils) and 787 private schools (194,613 pupils), a total of 2396 schools (1,003,237 pupils). A sample size of 75 940 pupils was estimated and 250 schools were drawn from a sample frame of 2396 schools using a stratified random sampling technique. Consent was obtained from the headmaster/head teacher of the selected schools who arranged a meeting with the tutor/teacher responsible for each class. The study team asked whether any of the pupils was ever noticed or known to have had any kind of seizures, and a confidential letter was sent to the parents of each identified pupil. The letter included an explanation of the aims of the study, information on the research group and the kind of help the research group could offer; contact numbers and email addresses were made available if they wished to participate in this study. Those who consented to participate were then given an appointment at the Epilepsy Outpatient Department, Gaafar Ibnauf Children's Hospital, Khartoum where they were evaluated by the paediatric neurologist.

RESULTS

Altogether, 74,949 pupils were enrolled for the study, 398 of whom were identified initially as having seizures and 332 of whom (83.4%) were identified by a paediatric neurologist. Of the 332, 303 (91.3%) proved to have epileptic seizures, 250 (82.5%) were known to have epilepsy, and 53 (17.5%) were newly diagnosed during the survey. The male to female ratio was 1.5:1. The total prevalence of epilepsy in Khartoum State was estimated to be 4/1000. The highest prevalence was in Jabal Awliya Locality (4.87/1000) and the lowest was in Khartoum Locality (3.35/1000). Twenty-nine (8.7%) patients proved to have non-epileptic seizures. The majority (15, 51.6%) had psychogenic non-epileptic seizures, and four (13.6%) had syncope. The majority (171, 56.43%) of patients had generalised epilepsy, 109 (35.97%) had focal epilepsy, and 23 (7.6%) had unclassified epilepsy.

CONCLUSION

The prevalence of epilepsy in school children in Khartoum State (4/1000) is higher than that reported previously from Khartoum Province in 1983 (0.9/1000).

The influence of epilepsy on children's perception of self-concept

The diagnosis of epilepsy can lead to changes in the patient's perception due to factors such as learning and behavioral problems, lack of academic motivation, and low self-esteem. This study aimed to evaluate and compare the knowledge of self-concept in children with epilepsy and those with typical development and verify whether gender and age influence this perception. Eighty children of both sexes, aged between 8 and 14years, participated in this study. The children were divided into two groups: the epilepsy group, which consisted of 40 children diagnosed with epilepsy, and the control group, which consisted of 40 children with typical development and comparable to group 1 according to sex and age. The Piers-Harris Children's Self-Concept Scale, translated and adapted for the Brazilian population, was used as the evaluation instrument. In total, there were 23 boys and 17 girls in each group, with a mean age of 10.7years. There were significant differences in the overall score (p=0.000) and the subareas "behavior" (p=0.006), "intellectual and academic status" (p=0.001), and "popularity" (p=0.004). The group of children with epilepsy had a lower average score in self-concept. Children with epilepsy were observed to perceive themselves as clumsy, without many friends, with low academic performance and problems at school, and to experiencing feelings of unhappiness. These findings suggest that, in addition to the treatment of the clinical manifestations of epilepsy, it is extremely important to provide treatment focused on improving the self-concept of school-aged children with this condition.

Epidemiology of epilepsy

Epilepsy is a burden affecting no fewer than 50 million patients worldwide. It is a heterogeneous group of disorders comprising both common and very rare forms, thus rendering its epidemiological investigations rather difficult. Moreover, making an epilepsy diagnosis per se can be challenging due to an evolving system of classification, and its dependency on local habits and culture. Any attempt at meta-analyses must consider such biases when pooling data from different centers and countries. Differentiating a contextual seizure from chronic epilepsy is every epileptologist's daily mission, yet it is also crucial for achieving a proper estimation of the epidemiology of epilepsy. Our present objective was to provide an overview of the epidemiology of both syndromic and non-syndromic epilepsy. Most epileptic syndromes tend to be rare and, thus, the feasibility of epidemiological quantification in populations is also addressed. Regarding its prevalence and cost, epilepsy deserves greater attention than it generally receives, as it appears to continue to be a condition under persistent taboos.

The biopsychosocial model and quality of life in persons with active epilepsy

BACKGROUND

Despite a long recognized need in the field of the importance of the psychological and social factors in persons with epilepsy (PWE), the medical community has continued to focus primarily on seizures and their treatment (the biological-biomedical model). From the biopsychosocial perspective, a person's lived experience needs to be incorporated into the understanding of quality of life. While the biopsychosocial model has gained prominence over the years, it has not been studied much in epilepsy.

METHODS

The study sample included 1720 PWE from the 2003 and the 2005 Canadian Community Health Survey (CCHS). Data were analyzed using set correlation, as it allows for the examination of the relative contribution of sets of independent variables (biological, psychological, and social domains) and a set of dependent variables (quality of life) of interest, defined as self-rated health status, self-rated mental health status, and life satisfaction.

RESULTS

Results provide strong evidence that the full biopsychosocial model explained a significantly larger amount of variance in quality of life (R(2) = 55.0%) compared with the biological-biomedical model alone (R(2) = 24.8%). When the individual domains of the biopsychosocial model were controlled for, the psychological (R(2) = 24.6%) and social (R(2) = 18.5%) domains still explained a greater amount of the variance in quality of life compared with the biological-biomedical model (R(2) = 14.3%).

CONCLUSIONS

While seizure freedom will continue to be an important treatment goal in epilepsy, the psychological and social domains are an important consideration for both interventional programs and clinical research designed to improve quality of life in PWE. Better integration of social workers and psychologists into routine care may help address these disparities.

A review of the quality of care following prolonged seizures in 1-18 year olds with epilepsies

PURPOSE

To review the quality of care of children and young people with epilepsies who, following a prolonged seizure, received high-dependency or intensive care. To identify and learn from clinical, organisational, management or personal issues that contributed to these admissions, in order to inform practice and improve clinical services for children across the UK.

METHOD

Notifications were collected from consultant paediatricians in England, Wales, Scotland and Northern Ireland over a 10-month period. For all eligible cases a clinical questionnaire was sent to the notifying clinician. A sample of these cases were selected for a detailed case note review. Case notes were reviewed by paediatrician-nurse pairs using a purpose-built assessment tool derived from national guidelines.

RESULTS

Data were collected from 135 clinical questionnaires, and 36 sets of case notes were reviewed. Findings were compared to national standards of care and emerging themes identified. There was evidence of good epilepsy management in many cases. In some cases there was evidence of a lack of clear emergency care plans, of delays in administration of emergency medication, and of deviation from established national guidelines.

CONCLUSION

The findings of this review suggest there have been improvements in the care of children and young people with epilepsies presenting with prolonged seizures compared to previous studies. Nevertheless, further improvements are needed, particularly in communication with families and prompt administration of emergency medication.

Biopsychosocial predictors of psychogenic non-epileptic seizures

BACKGROUND

Previous studies have identified numerous biological, psychological and social characteristics of persons with psychogenic non-epileptic seizures (PNES) however the strength of many of these factors have not been evaluated to determine which are predictive of the diagnosis compared to those that may only be stereotypes with limited clinical utility.

METHOD

A retrospective chart review of persons admitted to our epilepsy monitoring unit over a 6-year period was conducted to examine predictors of a video-EEG confirmed PNES diagnosis.

RESULTS

A total of 689 patients had events leading to a diagnosis, 47% (n=324) with PNES only, 12% (n=84) with PNES & Epilepsy and 41% (n=281) with Epilepsy only. Five biological predictors of a PNES only diagnosis were found; number of years with events (OR=1.10), history of head injury (OR=1.91), asthma (OR=2.94), gastro-esophageal reflux disease (OR=1.72) and pain (OR=2.25). One psychological predictor; anxiety (OR=1.72) and two social predictors; being married (OR=1.81) and history of physical/sexual abuse (OR=3.35). Two significant biological predictors of a PNES & Epilepsy diagnosis were found; migraine (OR=1.83) and gastro-esophageal reflux disease (OR=2.17).

CONCLUSIONS

Our findings support the importance of considering the biopsychosocial model for the diagnosis and treatment of PNES or PNES with concomitant epilepsy.

Prevalência dos fatores instrínsecos e extrínsecos do processo de aprendizagem em crianças com epilepsia

Objetivo levantar a prevalência dos fatores intrínsecos e extrínsecos que podem interferir no processo de aprendizagem em crianças com epilepsia. Métodos este estudo descritivo foi realizado no Ambulatório de Neurologia Infantil do Hospital de Pediatria Professor Heriberto Bezerra (HOSPED) da UFRN. A obtenção dos dados ocorreu durante setembro/2009 a março/2010 por meio da aplicação de um questionário com pais e cuidadores de crianças com epilepsia. A amostra foi constituída por 41 crianças, seguindo os seguintes critérios de inclusão: a) pais ou cuidadores de crianças com diagnóstico inequívoco de epilepsia atendidas no ambulatório do HOSPED; b) crianças com idades entre 3 e 12 anos; e c) pais ou responsáveis assinarem o termo de consentimento livre e esclarecido. Resultados 61% das crianças apresentaram diagnóstico de epilepsia pura. 59% tiveram sua primeira crise antes dos 03 anos de idade. 34% apresentavam crises do tipo generalizada. 51% apresentavam crises no período da pesquisa. 98% estavam em tratamento medicamentoso para controle das crises, sendo 55% monoterapia e 45% politerapia. 76% estavam inseridas na escola, sendo 50% em escolas públicas. 66% nunca repetiram o ano. 49% das crianças tiveram assiduidade escolar prejudicada em virtude das crises. 64% nunca foram excluídas da escola pelos professores devido a epilepsia e 85% dos pais afirmaram superproteger os filhos. Conclusão o estudo concluiu que, além da epilepsia, as crianças com essa patologia são também expostas a outros fatores, decorrentes da doença, que podem influenciar negativamente no processo de aprendizagem dessas crianças.

A model-based approach to understanding school status of students with epilepsy

This study constitutes a preliminary test of a theoretical model proposed by Sexson and Madan-Swain to explain the school status of students with epilepsy. Sixty-six classroom teachers participated in the study, as did 74 of their students with epilepsy. Three predictor variables-teachers' attitude towards persons with epilepsy, teachers' training in instructing students with epilepsy, and students' seizure frequency-were examined. Consistent with the model, the three variables collectively predicted attendance (F = 54.48, p<.001, R2 = 0.70), reading (F = 21.40, p<.001, R2 = .48), math (F = 12.61, p<.001, R2 = 0.35), writing (F = 12.61, p<.001, R2 = 0.35), and special education usage (χ2 = 30.96, p<.001). Moreover, both seizure frequency and teachers' attitude, but not teachers' training, uniquely predicted some outcome variables. Limitations and potential advantages of the model are discussed.

Cost of disorders of the brain in Europe 2010

BACKGROUND

The spectrum of disorders of the brain is large, covering hundreds of disorders that are listed in either the mental or neurological disorder chapters of the established international diagnostic classification systems. These disorders have a high prevalence as well as short- and long-term impairments and disabilities. Therefore they are an emotional, financial and social burden to the patients, their families and their social network. In a 2005 landmark study, we estimated for the first time the annual cost of 12 major groups of disorders of the brain in Europe and gave a conservative estimate of €386 billion for the year 2004. This estimate was limited in scope and conservative due to the lack of sufficiently comprehensive epidemiological and/or economic data on several important diagnostic groups. We are now in a position to substantially improve and revise the 2004 estimates. In the present report we cover 19 major groups of disorders, 7 more than previously, of an increased range of age groups and more cost items. We therefore present much improved cost estimates. Our revised estimates also now include the new EU member states, and hence a population of 514 million people.

AIMS

To estimate the number of persons with defined disorders of the brain in Europe in 2010, the total cost per person related to each disease in terms of direct and indirect costs, and an estimate of the total cost per disorder and country.

METHODS

The best available estimates of the prevalence and cost per person for 19 groups of disorders of the brain (covering well over 100 specific disorders) were identified via a systematic review of the published literature. Together with the twelve disorders included in 2004, the following range of mental and neurologic groups of disorders is covered: addictive disorders, affective disorders, anxiety disorders, brain tumor, childhood and adolescent disorders (developmental disorders), dementia, eating disorders, epilepsy, mental retardation, migraine, multiple sclerosis, neuromuscular disorders, Parkinson's disease, personality disorders, psychotic disorders, sleep disorders, somatoform disorders, stroke, and traumatic brain injury. Epidemiologic panels were charged to complete the literature review for each disorder in order to estimate the 12-month prevalence, and health economic panels were charged to estimate best cost-estimates. A cost model was developed to combine the epidemiologic and economic data and estimate the total cost of each disorder in each of 30 European countries (EU27+Iceland, Norway and Switzerland). The cost model was populated with national statistics from Eurostat to adjust all costs to 2010 values, converting all local currencies to Euro, imputing costs for countries where no data were available, and aggregating country estimates to purchasing power parity adjusted estimates for the total cost of disorders of the brain in Europe 2010.

RESULTS

The total cost of disorders of the brain was estimated at €798 billion in 2010. Direct costs constitute the majority of costs (37% direct healthcare costs and 23% direct non-medical costs) whereas the remaining 40% were indirect costs associated with patients' production losses. On average, the estimated cost per person with a disorder of the brain in Europe ranged between €285 for headache and €30,000 for neuromuscular disorders. The European per capita cost of disorders of the brain was €1550 on average but varied by country. The cost (in billion €PPP 2010) of the disorders of the brain included in this study was as follows: addiction: €65.7; anxiety disorders: €74.4; brain tumor: €5.2; child/adolescent disorders: €21.3; dementia: €105.2; eating disorders: €0.8; epilepsy: €13.8; headache: €43.5; mental retardation: €43.3; mood disorders: €113.4; multiple sclerosis: €14.6; neuromuscular disorders: €7.7; Parkinson's disease: €13.9; personality disorders: €27.3; psychotic disorders: €93.9; sleep disorders: €35.4; somatoform disorder: €21.2; stroke: €64.1; traumatic brain injury: €33.0. It should be noted that the revised estimate of those disorders included in the previous 2004 report constituted €477 billion, by and large confirming our previous study results after considering the inflation and population increase since 2004. Further, our results were consistent with administrative data on the health care expenditure in Europe, and comparable to previous studies on the cost of specific disorders in Europe. Our estimates were lower than comparable estimates from the US.

DISCUSSION

This study was based on the best currently available data in Europe and our model enabled extrapolation to countries where no data could be found. Still, the scarcity of data is an important source of uncertainty in our estimates and may imply over- or underestimations in some disorders and countries. Even though this review included many disorders, diagnoses, age groups and cost items that were omitted in 2004, there are still remaining disorders that could not be included due to limitations in the available data. We therefore consider our estimate of the total cost of the disorders of the brain in Europe to be conservative. In terms of the health economic burden outlined in this report, disorders of the brain likely constitute the number one economic challenge for European health care, now and in the future. Data presented in this report should be considered by all stakeholder groups, including policy makers, industry and patient advocacy groups, to reconsider the current science, research and public health agenda and define a coordinated plan of action of various levels to address the associated challenges.

RECOMMENDATIONS

Political action is required in light of the present high cost of disorders of the brain. Funding of brain research must be increased; care for patients with brain disorders as well as teaching at medical schools and other health related educations must be quantitatively and qualitatively improved, including psychological treatments. The current move of the pharmaceutical industry away from brain related indications must be halted and reversed. Continued research into the cost of the many disorders not included in the present study is warranted. It is essential that not only the EU but also the national governments forcefully support these initiatives.

The prevalence and management of epilepsy in secondary school pupils with and without special educational needs

OBJECTIVES

The objectives of this paper were to (i) determine the prevalence of epilepsy (including the various epilepsies and epilepsy syndromes) in a secondary school population; and (ii) compare the management of epilepsy between secondary school pupils with and without special educational needs.

METHODS

Retrospective observational study of a 250, 000 population (West Cheshire Health District). Pupils attending secondary school with epilepsy over a 1-year period were identified from the local Child Health Computer, school nurse and DGH records. Health records were examined to determine the prevalence, characteristics and management of the epilepsy, and the presence of any special educational needs, other learning difficulties or physical disability.

RESULTS

The prevalence of epilepsy was 4.1 per 1000, being 10 times higher among adolescents who had special educational needs. Pupils with epilepsy and special educational needs had more poorly controlled epilepsy, but did not have a higher number of focal seizures nor were they taking a greater number of anti-epileptic drugs. A physical disability occurred five times more often in those with special educational needs and epilepsy. While epilepsy in pupils at mainstream school without special educational needs was better controlled, one-fifth of these subjects had poorly controlled epilepsy and a few also had physical disabilities.

CONCLUSIONS

Epilepsy is more challenging to control in adolescents with special educational needs attending special schools. However, some pupils in mainstream secondary schools had poorly controlled epilepsy even when they did not have recognized special educational needs. Health and education professionals working across the range of secondary school environments need to be able to support pupils with challenging epilepsy, many of whom will also have special educational needs and some a physical disability, as an increasing number of adolescents with these difficulties are being placed in mainstream schools.

Estimation of the burden of active and life-time epilepsy: a meta-analytic approach

PURPOSE

To estimate the burden of lifetime epilepsy (LTE) and active epilepsy (AE) and examine the influence of study characteristics on prevalence estimates.

METHODS

We searched online databases and identified articles using prespecified criteria. Random-effects meta-analyses were used to estimate the median prevalence in developed countries and in urban and rural settings in developing countries. The impact of study characteristics on prevalence estimates was determined using meta-regression models.

RESULTS

The median LTE prevalence for developed countries was 5.8 per 1,000 (5th-95th percentile range 2.7-12.4) compared to 15.4 per 1,000 (4.8-49.6) for rural and 10.3 (2.8-37.7) for urban studies in developing countries. The median prevalence of AE was 4.9 per 1,000 (2.3-10.3) for developed countries and 12.7 per 1,000 (3.5-45.5) and 5.9 (3.4-10.2) in rural and urban studies in developing countries. The estimates of burden for LTE and AE in developed countries were 6.8 million (5th-95th percentile range 3.2-14.7) and 5.7 million (2.7-12.2), respectively. In developing countries these were 45 (14-145) million LTE and 17 (10-133) million AE in rural areas and 17 (5-61) million LTE and 10 (5-17) million AE in urban areas. Studies involving all ages or only adults showed higher estimates than pediatric studies. Higher prevalence estimates were also associated with rural location and small study size.

CONCLUSIONS

This study estimates the global burden of epilepsy and the proportions with AE, which may benefit from treatment. There are systematic differences in reported prevalence estimates, which are only partially explained by study characteristics.

Estimating the cost of epilepsy in Europe: a review with economic modeling

PURPOSE

Based on available epidemiologic, health economic, and international population statistics literature, the cost of epilepsy in Europe was estimated.

METHODS

Europe was defined as the 25 European Union member countries, Iceland, Norway, and Switzerland. Guidelines for epidemiological studies on epilepsy were used for a case definition. A bottom-up prevalence-based cost-of-illness approach, the societal perspective for including the cost items, and the human capital approach as valuation principle for indirect costs were used. The cost estimates were based on selected studies with common methodology and valuation principles.

RESULTS

The estimated prevalence of epilepsy in Europe in 2004 was 4.3-7.8 per 1,000. The estimated total cost of the disease in Europe was euro15.5 billion in 2004, indirect cost being the single most dominant cost category (euro8.6 billion). Direct health care costs were euro2.8 billion, outpatient care comprising the largest part (euro1.3 billion). Direct nonmedical cost was euro4.2 billion. That of antiepileptic drugs was euro400 million. The total cost per case was euro2,000-11,500 and the estimated cost per European inhabitant was euro33.

CONCLUSIONS

Epilepsy is a relevant socioeconomic burden at individual, family, health services, and societal level in Europe. The greater proportion of such burden is outside the formal health care sector, antiepileptic drugs representing a smaller proportion. Lack of economic data from several European countries and other methodological limitations make this report an initial estimate of the cost of epilepsy in Europe. Prospective incidence cost-of-illness studies from well-defined populations and common methodology are encouraged.

The epidemiology of epilepsy in Europe - a systematic review

Population-based epidemiological studies on epilepsy are available mainly from the UK and the Nordic, Baltic and western Mediterranean countries. No studies were identified from large areas of Europe, especially from the former eastern Europe (except the Baltic countries) and the eastern Mediterranean countries. Based on the prevalence of epilepsy in different studies and accounting for incomplete case identification the estimated number of children and adolescents in Europe with active epilepsy is 0.9 million (prevalence 4.5-5.0 per 1000), 1.9 million in ages 20-64 years (prevalence six per 1000) and 0.6 million in ages 65 years and older (prevalence seven per 1000). Approximately 20-30% of the epilepsy population have more than one seizure per month. Based on the age-specific incidence rates in European studies, the estimated number of new cases per year amongst European children and adolescents is 130,000 (incidence rate 70 per 100,000), 96,000 in adults 20-64 years (incidence rate 30 per 100,000) and 85,000 in the elderly 65 years and older (incidence 100 per 100,000). The proportion of both new and established cases with epilepsy in the young, adults and elderly in individual countries may differ substantially from total European distribution because of differences in age structure.

Study of seizure and epilepsy in Chinese children in Hong Kong: period prevalence and patterns

The Hong Kong Children's Seizure and Epilepsy Registry was set up for all children with a history of seizures or epilepsy followed up in the Epilepsy Clinic of the University of Hong Kong. The aim was to study the pattern of seizures and epileptic disorders in Chinese children. The objective was to study the period prevalence of epilepsy and the pattern of epilepsy in Chinese children. A prospective study of seizure and epilepsy in Chinese children was conducted from 1985 to 1997 in Hong Kong. The population census of 1997 was used to calculate the period prevalence of epilepsy in Chinese children. Altogether, 1103 children aged < 19 years at first assessment with epilepsy were included in the study. The period prevalence rate of epilepsy in 1997 (January to December) is estimated to be 4.5 per 1000 children aged < 19 years. The estimated period prevalence rate of children and adolescents with epilepsy in our children is 4.5 per 1000 children.
