Prevalence and pattern of epilepsy (Lath/Mirgi/Laran) in rural Kashmir, India

Prevalence of pediatric and adolescent epilepsy in India: A systematic review and meta-analysis

INTRODUCTION

Epilepsy is a widespread neurological disorder that affects millions of people worldwide, with a large proportion of cases emerging in childhood. Many children with epilepsy in low and middle-income countries, such as India, encounter obstacles to care despite effective treatments, which add to the treatment gap.

METHODOLOGY

A systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. PubMed, Scopus and Shodhganga databases were searched for studies on epilepsy prevalence in pediatric and adolescent groups aged 0 to 19 years in India. Eligible studies were identified, and data were collected and synthesised using random-effect models. Geographic zones and gender were used to conduct subgroup analysis.

RESULTS

Thirteen community-based studies with seventeen datasets satisfied the inclusion requirements. The overall pooled prevalence of paediatric and adolescent epilepsy in India is 0.8 % (95 % CI: 0.6 %, 1.0 %). Significant variation was found among Indian zones according to subgroup analysis, with the Central zone showing the lowest prevalence (0.4 %) and the North-Eastern zone showing the highest prevalence (2.3 %). A Doi plot revealed major asymmetry with an LFK index of 4.24, indicating publication bias and small study effects. The studies had a high degree of heterogeneity (I2 = 93 %).

CONCLUSION

In India, epilepsy affects a large number of children and families, posing a significant public health burden. Effective management requires age-specific strategies for specialised interventions and full support services. This study underscores the necessity of improving healthcare access and addressing the treatment gap for children with epilepsy in India.

Epilepsy Among School-Children in a Rural District in Northwest India: Prevalence Estimates Using Three Different Approaches

OBJECTIVES

To estimate and compare the prevalence of epilepsy during childhood using several approaches and also to determine whether school-based screening campaigns can capture epilepsy cases efficiently.

METHODS

Epilepsy prevalence determined from cases captured through the Rashtriya Bal Swasthya Karyakram (RBSK), a nationwide school-health screening framework, were compared with estimates derived from school- and community-based surveys in one Indian district. Level-1 screen comprised perusal of child health registers maintained by the RBSK teams over one year to estimate the documented number of children with epilepsy; Level-2 screen comprised a questionnaire-based school survey among 10,000 school children; and Level-3 screen-a door-to-door community-based survey among 10,000 children in the district.

RESULTS

Prevalence estimates of childhood epilepsy varied significantly across screening methods. The child health register identified lower crude and age-adjusted prevalences of 40 (95% CI, 24 to 55) and 36 (95% CI, 20 to 51)/1,00,000 vis-à-vis both the school survey [crude and age-adjusted prevalences of 354 (95% CI, 221 to 487) and 340 (95% CI, 181 to 517) per 100,000] and the community survey [crude and age-adjusted prevalences of 759 (95% CI, 591 to 927) and 746 (95% CI, 579 to 914) per 100,000]. The community survey identified 15 children with epilepsy (20%) who had dropped out of school. Also, it recaptured a small number of children previously identified by the school or child health register surveys.

CONCLUSIONS

The present findings underscore the need to scale up the capacity of public programs to screen epilepsy among school children and underline the high frequency of school dropouts among children with epilepsy in resource-limited settings.

Prevalence of psychiatric disorders among the adult population in a rural community of Jammu, India: a cross-sectional study

Background

Mental health is crucial for overall well-being, but rural areas often face difficulties in accessing mental health services and understanding psychiatric disorders.

Aim

This study aimed to address these issues by assessing the prevalence of psychiatric disorders among adults in rural Jammu and examining how socio-cultural and demographic factors are related to these disorders.

Methods

A sample of 1,016 adults from rural Jammu was surveyed using the Mini International Neuropsychiatric Interview (MINI). Data were collected through house-to-house visits conducted by trained investigators. Descriptive and inferential statistics, including frequency distribution and odds ratio, were employed to analyze the data respectively.

Results

Overall, 20.67% of the participants had a psychiatric disorder. Alcohol dependence was the most common condition, affecting 12.30% of the individuals, followed by generalized anxiety disorder at 3.14%. The study found significant associations between psychiatric disorders and several factors. Specifically, older people were more likely to have psychiatric disorders, with an odds ratio of 3.7 [2.07-6.59]. Married individuals also had a higher likelihood of experiencing psychiatric disorders (OR: 2.3 [1.55-3.54]). Those with less schooling were at an increased risk, with an odds ratio of 7.77 [2.31-26.09], and people from lower socioeconomic backgrounds were more likely to have these disorders as well (OR: 5.1 [2.4-10.5]).

Discussion and conclusion

The findings underscore the complex association between socio-demographic factors and mental health outcomes in rural areas of Jammu region. Addressing these disparities requires targeted interventions and policies that account for the unique socio-cultural contexts of rural populations. By understanding the specific challenges faced by these communities, policymakers and healthcare providers can develop more effective strategies to enhance mental health services and promote well-being.

The landscape of infantile epileptic spasms syndrome in South Asia: peculiarities, challenges, and way forward

Infantile Epileptic Spasms Syndrome (IESS), commonly known as West syndrome, is the most common cause of infantile-onset epileptic encephalopathy. There is a peculiar epidemiological profile of IESS in South Asia. Specific features identified were a preponderance of acquired structural aetiology, male gender dominance, a long treatment lag, limited availability of adrenocorticotropic hormone (ACTH) and vigabatrin, and use of carboxymethyl cellulose derivative of ACTH. Because of the significant disease burden and limited resources, there are distinctive challenges to the optimal care of children with IESS in the South Asian region. Also, there are unique opportunities to bridge these challenges and improve outcomes. This review provides an overview of the landscape of IESS in South Asia and highlights its peculiarities, various challenges, and way forward.

Classifying etiology of infantile spasms syndrome in resource-limited settings: A study from the South Asian region

Objective

Etiological classification of infantile spasms syndrome (ISS) is important, considering the influence on prognosis based on the presence or absence of a known etiology. This study was performed to describe the limitations and difficulties experienced within the South Asian region when classifying the etiology of ISS according to the current recommendation.

Method

Data on healthcare indices and facilities related to management of ISS for the nine countries in the South Asian region were gathered by the South Asian West Syndrome Research Group. A Google survey was performed among three hundred and thirty pediatric neurologists in the region. The capacity within each country for investigating etiology of ISS according to current described benchmarks was evaluated. The difficulties experienced in this regard and the potential solutions were investigated.

Results

One hundred and sixty pediatric neurologists (response rate 48%) from Bangladesh (19/25), India (94/255), Myanmar (11/11), Nepal (6/8), Pakistan (19/25), and from Sri Lanka (7/8) responded. Three countries had no pediatric neurology services. Fifty‐six percent attempted to classify ISS etiology according to classification outlined by International League Against Epilepsy in 2017. The facilities to perform metabolic, genetic, and immunological investigations were very limited. Lack of funding for investigations and poor laboratory support were the two most frequent barriers encountered. Sixty percent indicated that a separate classification is suitable for low‐income setting; 78% suggested inclusion of separate category as “incompletely investigated” as an alternative solution to mitigate the barrier of achieving a better understanding of the etiological subtypes seen more frequently in this region.

Significance

The resources in South Asian region are limited to meet the recommendations for investigating etiology of ISS. Including the etiological subcategory “incompletely investigated” is proposed as an alternative to understand the true proportions of children in this region, with a definite known etiology and those with an unknown etiology.

Epidemiology of Epilepsy in Nigeria: A Community-Based Study From 3 Sites

BACKGROUND

We determined the prevalence, incidence, and risk factors for epilepsy in Nigeria.

METHODS

We conducted a door-to-door survey to identify cases of epilepsy in 3 regions. We estimated age-standardized prevalence adjusted for nonresponse and sensitivity and the 1-year retrospective incidence for active epilepsy. To assess potential risk factors, we conducted a case-control study by collecting sociodemographic and risk factor data. We estimated odds ratios using logistic regression analysis and corresponding population attributable fractions (PAFs).

RESULTS

We screened 42,427 persons (age ≥6 years), of whom 254 had confirmed active epilepsy. The pooled prevalence of active epilepsy per 1,000 was 9.8 (95% confidence interval [CI] 8.6-11.1), 17.7 (14.2-20.6) in Gwandu, 4.8 (3.4-6.6) in Afikpo, and 3.3 (2.0-5.1) in Ijebu-Jesa. The pooled incidence per 100,000 was 101.3 (95% CI 57.9-167.6), 201.2 (105.0-358.9) in Gwandu, 27.6 (3.3-128.0) in Afikpo, and 23.9 (3.2-157.0) in Ijebu-Jesa. Children's significant risk factors included febrile seizures, meningitis, poor perinatal care, open defecation, measles, and family history in first-degree relatives. In adults, head injury, poor perinatal care, febrile seizures, family history in second-degree relatives, and consanguinity were significant. Gwandu had more significant risk factors. The PAF for the important factors in children was 74.0% (71.0%-76.0%) and in adults was 79.0% (75.0%-81.0%).

CONCLUSION

This work suggests varied epidemiologic numbers, which may be explained by differences in risk factors and population structure in the different regions. These variations should differentially determine and drive prevention and health care responses.

Need for pharmacoeconomic consideration of antiepileptic drugs monotherapy treatment in persons with epilepsy

Objective

Newer antiepileptic drugs (AEDs) are expected to have less adverse effects (AEs) and drug interactions as compared to conventional AEDs but the high cost is the major limitation for their use. This study evaluated variation in the cost of treatment with newer and conventional AEDs through its correlation with treatment efficacy and AEs in persons with epilepsy (PWE).

Methods

This cross-sectional study included PWE (28.9 ± 9.9 years) having focal and generalized seizures on conventional [valproate, carbamazepine, phenytoin] or newer AEDs [levetiracetam, oxcarbazepine] for >6 months. Seizure frequency during the study (6 months) was compared to that within 6 months before the study. Other parameters assessed were Quality of life in epilepsy, Pittsburgh Sleep Quality Index, Gastrointestinal Quality of life Index, and Liverpool AEs Profile. The cost of treatment was determined as direct, indirect, and intangible costs. The incremental cost-effectiveness ratio (ICER) analysis was also performed.

Results

Out of 214 PWE, 51.4% were on newer AEDs. Newer and conventional AEDs did not differ significantly in seizure frequency reduction (60.29 vs. 53.09%), quality of life parameters, though these were improved significantly during the study period. The direct medical cost and total cost of treatment were lesser with conventional AEDs (p < 0.001 in both) than newer AEDs, but the intangible cost did not differ. The total cost of treatment was significantly influenced by factors (as per regression analysis) including the type of AEDs (significant difference between valproate, carbamazepine, and levetiracetam), frequency of seizures, cost of medicine (70.34% of total cost), hospital admission, and treatment of AEs. As per ICER, newer AEDs need an additional USD 8.39 per unit reduction in seizure frequency.

Conclusion

Newer AEDs have comparatively better efficacy, though not significant than conventional AEDs. However, the additional cost per unit improvement is quite high with newer AEDs, necessitating pharmacoeconomic consideration in epilepsy treatment.

Comorbidities of epilepsy in low and middle-income countries: systematic review and meta-analysis

Epilepsy is a major public health concern in low and middle-income countries (LMICs) and comorbidities aggravate the burden associated with the disease. The epidemiology of these comorbidities has not been well described, although, identifying the main comorbidities of epilepsy, and their relative importance, is crucial for improving the quality of care. Comorbidities were defined as disorders coexisting with or preceding epilepsy, or else compounded or directly attributed to epilepsy or to its treatment. A meta-analysis of the proportion of main comorbidities by subcontinent as well as overall was also conducted. Out of the 2,300 papers identified, 109 from 39 countries were included in this systematic review. Four groups of comorbidities were identified: parasitic and infectious diseases (44% of comorbid conditions), somatic comorbidities (37%), psychosocial (11%), as well as psychiatric comorbidities (8%). Heterogeneity was statistically significant for most variables then random effect models were used. The most frequently studied comorbidities were: neurocysticercosis (comorbid proportion: 23%, 95% CI: 18-29), head trauma (comorbid proportion: 9%, 95% CI: 5-15) malnutrition (comorbid proportion: 16%, 95% CI: 28-40), stroke (comorbid proportion: 1.3%, 95% CI: 0.2-7.0), and discrimination for education (comorbid proportion: 34%, 95% CI: 28-40). Many comorbidities of epilepsy were identified in LMICs, most of them being infectious.

Latitudinal differences on the global epidemiology of infantile spasms: systematic review and meta-analysis

BACKGROUND

Infantile spasms represent the catastrophic, age-specific seizure type associated with acute and long-term neurological morbidity. However, due to rarity and heterogenous determination, there is persistent uncertainty of its pathophysiological and epidemiological characteristics. The purpose of the current study was to address a historically suspected latitudinal basis of infantile spasms incidence, and to interrogate a geographical basis of epidemiology, including the roles of latitude and other environmental factors, using meta-analytic and -regression methods.

METHODS

A systematic search was performed in Ovid MEDLINE and Embase for primary reports on infantile spasms incidence and prevalence epidemiology.

RESULTS

One thousand fifteen studies were screened to yield 54 eligible publications, from which 39 incidence figures and 18 prevalence figures were extracted. The pooled incidence was 0.249 cases/1000 live births. The pooled prevalence was 0.015 cases/1000 population. Univariate meta-regression determined a continental effect, with Europe demonstrating the highest onset compared from Asia (OR = 0.51, p = 0.004) and from North America (OR = 0.50, p = 0.004). Latitude was also positively correlated with incidence globally (OR = 1.02, p < 0.001). Sub-analyses determined a particularly elevated Scandinavian incidence compared to the rest of world (OR = 1.88, p < 0.001), and lack of latitudinal effect with Scandinavian exclusion (p = 0.10). Metrics of healthcare quality did not predict incidence. Multiple meta-regression determined that latitude was the key predictor of incidence (OR = 1.02, p = 0.001).

CONCLUSIONS

This is the first systematic epidemiological study of infantile spasms. Limitations included lack of Southern hemispheric representation, insufficient study selection and size to support some sub-continental analyses, and lack of accessible ethnic and healthcare quality data. Meta-analyses determined a novel, true geographical difference in incidence which is consistent with a latitudinal and/or ethnic contribution to epileptogenesis. These findings justify the establishment of a global registry of infantile spasms epidemiology to promote future systematic studies, clarify risk factors, and expand understanding of the pathophysiology.

Prevalence, Demographic Profile, and Psychological Aspects of Epilepsy in North-Western India: A Community-Based Observational Study

Aims

This study was undertaken to determine the prevalence of active epilepsy, assess the sociodemographic profile, and psychological aspects of epilepsy in the Jaipur district of Rajasthan, India.

Methods

We conducted a community-based, cross-sectional observational study covering both rural (n = 165,660) and urban (n = 179,142) populations of Jaipur district using a house-to-house survey. An adapted, pre-designed World Health Organization screening questionnaire was used to identify the cases. Those confirmed by neurologists as true seizures were included in the study. Cases were classified as per the International League against Epilepsy recommendation. Global Mental Health Assessment Tool electronic questionnaire was used to analyze psychological aspects of cases. The caregivers of the patients participated in the knowledge, attitude, and practice (KAP) survey.

Results

A total of 380 patients (258 men, 122 women) were identified with active epilepsy. The estimated prevalence of active epilepsy was 1.1/1,000 population and 71% of cases belonged to low socioeconomic classes. Primary treatment gap was documented in 18.8% of cases in our study, 38% of cases were non-compliant to treatment with poorer compliance in those on pol-therapy, 76% had some psychiatric disorder, anxiety and depression being the commonest, and positive family history of epilepsy was found in 4.7%. KAP survey revealed that only 15% of the respondents believed that epilepsy is non-curable, 74% denied its infectious nature, 26% believed that epilepsy occurs due to past sins, and 81% said that they would not marry persons with epilepsy.

Conclusion

A relatively low prevalence (1.1/1,000) of active epilepsy and a smaller primary treatment gap (18.8%) was found in our study population. Almost three-fourth of cases had an associated psychological problem, Though caregivers were aware of the nature of disease, majority would not prefer to marry a person suffering from epilepsy.

Burden of neurodevelopmental disorders in low and middle-income countries: A systematic review and meta-analysis

Background: Childhood mortality from infectious diseases has declined steadily in many low and middle-income (LAMIC) countries, with increased recognition of non-communicable diseases such as neurodevelopmental disorders (NDD). There is lack of data on the burden of NDD in LAMIC. Current global burden of these disorders are largely extrapolated from high-income countries. The main objective of the study was therefore to estimate the burden of NDD in LAMIC using meta-analytic techniques. Methods: We systematically searched online databases including Medline/PubMed, PsychoInfo, and Embase for studies that reported prevalence or incidence of NDD. Pooled prevalence, heterogeneity and risk factors for prevalence were determined using meta-analytic techniques.   Results: We identified 4,802 records, but only 51 studies met the eligibility criteria. Most studies were from Asia-Pacific (52.2%) and most were on neurological disorders (63.1%). The median pooled prevalence per 1,000 for any NDD was 7.6 (95%CI 7.5-7.7), being 11.3 (11.7-12.0) for neurological disorders and 3.2 (95%CI 3.1-3.3) for mental conditions such as attention-deficit hyperactivity disorder (ADHD). The type of NDD was significantly associated with the greatest prevalence ratio in the multivariable model (PR=2.6(95%CI 0.6-11.6) (P>0.05). Incidence was only reported for epilepsy (mean of 447.7 (95%CI 415.3-481.9) per 100,000). Perinatal complications were the commonest risk factor for NDD. Conclusion: The burden of NDD in LAMIC is considerable. Epidemiological surveys on NDD should screen all types of NDD to provide reliable estimates.

Prevalence of Unrecognized Autism Spectrum Disorders in Epilepsy: A Clinic-Based Study

Objective

To assess prevalence of unrecognized autism spectrum disorders (ASDs) in children with epilepsy using Diagnostic and Statistical Manual IV (DSM-IV) criteria and to evaluate factors affecting it in this population. It was a cross-sectional study conducted at a teaching hospital. It included randomly selected 106 children in the age 4-12 years with epilepsy, and without any structural anomaly identifiable on computed tomography/magnetic resonance imaging. Children already diagnosed with ASD were excluded.

Materials and Methods

Detailed clinical evaluation was carried out. Intelligence quotient (IQ) was assessed using Development Profile-II for all and Binet and Kulshrestha test, wherever possible. Participants were screened using Social Communication Questionnaire (SCQ). Those with SCQ score of ≥15 were evaluated for ASD using DSM-IV criteria. Childhood Autism Rating Scale was administered to assess the severity of autism. Data were analyzed with univariate and logistic regression analyses.

Results

A total of nine children were screened positive, of them, eight were diagnosed with ASD using DSM-IV criteria. The prevalence of unrecognized ASD was 7.5/100. On univariate analysis, intellectual disability (P < 0.01) and young age of onset of epilepsy (P = 0.03) were significantly associated with ASD. On multivariable analysis, only intellectual disability was significantly associated with ASD (P < 0.01). There was no significant association with gender, seizure type, frequency of seizures, intractability of epilepsy, or the number of antiepileptic drugs used.

Conclusion

ASDs are more prevalent in children with epilepsy than in general population. In cases with associated intellectual disability, co-occurrence of ASD is further increased. All children with epilepsy, particularly those with IQ ≤ 50, irrespective of age of onset of epilepsy, seizure type, frequency of seizures, or intractability of epilepsy, should be screened for ASD.

Conclusion: The burden of NDD in LAMIC is considerable. Epidemiological surveys on NDD should screen all types of NDD to provide reliable estimates.

Recent Drug Resistant Epilepsy Spectrum in Eastern India

Background and Purpose

The Magnitude of Drug-resistant Epilepsy (DRE) in India, being unknown, takes a heavy toll on the patients and society in the form of prolonged dependence, unemployment, morbidity and mortality. We tried to explore the clinical, electro-physiological, neuro-imaging and drug-response spectrum of DRE patients in Eastern India in our study.

Methods

During the period of January 2014 to December 2015, epilepsy patients were treated and DRE patients were identified according to International League Against Epilepsy criteria. We isolated those patients and studied them in a special clinic.

Results

Among 2,153 patients treated in Neurology out-patient department, 243 (11.3%) patients were drug-resistant. Among the DRE patients, 63% were male. Age-wise 40%, 30.5% & 18.1% patients were presented in their first, second and third decades respectively. Males were more affected in 0–5 years age group while females in 6–10 years age group. Various seizures types were found alone or in combination. Males were mostly affected by generalized tonic clonic seizure and myoclonus and females by complex partial seizure. Positive family history was higher in partial seizure group. Electroencephalographic (EEG) abnormalities were common with structural lesions in brain. EEG findings in different etiologies were varied with a large number of DRE patients who were found to have normal EEG. Females were higher medicine non-compliant.

Conclusions

The spectrum was pointed towards gender predilection for specific age group and also for seizure types. Idiopathic cases were most common in DRE, pointing towards the need of newer investigations. Normal EEG could be found even in a DRE patient. Non-compliance was more in females.

Epilepsy in Developing Countries

The management of epilepsy in developing countries requires cultural knowledge and approaches beyond the usual practices of western medicine. This paper focuses on explanatory mod els of epilepsy in different cultures throughout Africa, India, China, South America, and the Middle East. It examines the social impact of epilepsy on individuals, families and commu nities. The role of traditional healing practices is reviewed, along with new policies for allocation of scarce health care resources for the treatment of epilepsy in the developing world.

Knowledge, attitude, and practice of people toward epilepsy in a South Indian village

Introduction:

People living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions, and misunderstandings that have persisted for many years. In the last decade, there has been an increase in individual literacy rate and increased access to technology in rural population. However, it is unclear if this has any effect on knowledge, attitude, and practice (KAP) attitude toward epilepsy.

Objective:

Our primary aim is to evaluate KAP toward epilepsy. In addition, we also estimated the prevalence of stroke and epilepsy in rural South India.

Materials and Methods:

Using a 14-item questionnaire, we assessed KAP toward epilepsy and identified determinants of inappropriate attitudes toward people with epilepsy and 10-item questionnaires to assess the prevalence of epilepsy and stroke among 500 randomly selected populations in a Pattaravakkam village (Tamil Nadu, India).

Results:

About 87.7% of the people had heard or read about epilepsy. Negative attitudes appeared to be reinforced by beliefs that epilepsy is hereditary (23.1%), kind of insanity (22.6%), or as contagious (12.0%). The knowledge about the clinical characteristics and first aid to a person during a seizure was 25.8%. About 36.5% of people think that society discriminates people with epilepsy. Moreover, our prevalence study showed that 8.7% people are suffering from epilepsy and 3.7% had stroke previously and at the day of survey, the stroke prevalence is 3.3%.

Conclusion:

Even with increased literacy, technology, and communication devices, the KAP of people toward epilepsy is relatively low. General public education campaigns and specific school education campaigns children should be encouraged to increase the KAP toward epilepsy. The prevalence and pattern of epilepsy and stroke is on the higher side in the village of Pattaravakkam. Future research regarding the value of targeted education in improving KAP will be worthwhile.

Knowledge and Attitude toward Epilepsy of Close Family Members of People with Epilepsy in North of Iran

Background. Knowledge and attitudes are required for relatives of people with epilepsy to allow them to better understand and cope with this condition. This study evaluated the knowledge and attitudes of family members of people with epilepsy about the disease. Methods. This cross-sectional survey was conducted using a self-administered questionnaire completed by close family members of people with epilepsy at the outpatient clinic of a medical university. The questionnaire included 25 items that determined the demographics and information on the level of knowledge and attitudes about epilepsy. Results. The 124 participants had an average age of 36.88 ± 10.68 years. The mean knowledge score was 10.32 ± 2.25 (range: 4 to 15). 87.1% of respondents answered that epilepsy is a brain disorder, 39 (31.5%) said epilepsy is inherited. As a whole, 62 (50%) had good knowledge about the disease. The mean score of attitude was 7.25 ± 1.54 (range: 2 to 10). 83.9% of respondents believed that a person with epilepsy can get married and get pregnant (76.6%). Overall, 15 (12.1%) had negative attitudes and 109 (87.9%) had positive attitudes. Conclusion. The main findings of this study indicated good knowledge and a positive attitude about epilepsy among family members of people with epilepsy.

Epilepsy in India II: Impact, burden, and need for a multisectoral public health response

Epilepsy is a common neurological disorder whose consequences are influenced socially and culturally, especially in India. This review (second of the two part series) was carried out to understand the social impact and economic burden to develop comprehensive program for control and prevention of epilepsy. Epilepsy is known to have adverse effect on education, employment, marriage, and other essential social opportunities. Economic burden associated with epilepsy is very high with treatment and travel costs emerging as an important contributing factor. A vicious cycle between economic burden and poor disease outcome is clear. There is no significant change in the perception, stigma, and discrimination of epilepsy across the country despite improvement in educational and social parameters over the time. The huge treatment gap and poor quality of life is further worsened by the associated comorbidities and conditions. Thus, a multidisciplinary response is needed to address the burden and impact of epilepsy which calls for an integrated and multipronged approach for epilepsy care, prevention, and rehabilitation. Service delivery, capacity building, integration into the existing program, mobilizing public support, and increasing public awareness will be the hallmarks of such an integrated approach in a public health model.

Epilepsy in India I: Epidemiology and public health

Of the 70 million persons with epilepsy (PWE) worldwide, nearly 12 million PWE are expected to reside in India; which contributes to nearly one-sixth of the global burden. This paper (first of the two part series) provides an in-depth understanding of the epidemiological aspects of epilepsy in India for developing effective public health prevention and control programs. The overall prevalence (3.0-11.9 per 1,000 population) and incidence (0.2-0.6 per 1,000 population per year) data from recent studies in India on general population are comparable to the rates of high-income countries (HICs) despite marked variations in population characteristics and study methodologies. There is a differential distribution of epilepsy among various sociodemographic and economic groups with higher rates reported for the male gender, rural population, and low socioeconomic status. A changing pattern in the age-specific occurrence of epilepsy with preponderance towards the older age group is noticed due to sociodemographic and epidemiological transition. Neuroinfections, neurocysticercosis (NCC), and neurotrauma along with birth injuries have emerged as major risk factors for secondary epilepsy. Despite its varied etiology (unknown and known), majority of the epilepsy are manageable in nature. This paper emphasizes the need for focused and targeted programs based on a life-course perspective and calls for a stronger public health approach based on equity for prevention, control, and management of epilepsy in India.

Prevalence and Incidence of Epilepsy in an Elderly and Low-Income Population in the United States

Background and Purpose

The purpose of this study was to estimate the incidence and prevalence of epilepsy among an elderly and poor population in the United States.

Methods

Arizona Medicaid claims data from January 1, 2008 to December 31, 2010 were used for this analysis. Subjects who were aged ≥65 years and were continuously enrolled in any Arizona Medicaid health plans (eligible to patients with low income) for ≥12 months between January 1, 2008 and December 31, 2009 were considered eligible for inclusion in the study cohort. In addition to meeting the aforementioned criteria, incident and prevalent cases must have had epilepsy-related healthcare claims. Furthermore, incident cases were required to have a 1-year "clean" period immediately preceding the index date. Negative binomial and logistic regression models were used to assess the factors associated with epilepsy incidence and prevalence.

Results

The estimated epilepsy incidence and prevalence for this population in 2009 were 7.9 and 19.3 per 1,000 person-years, respectively. The incidence and prevalence rates were significantly higher for patients with comorbid conditions that were potential risk factors for epilepsy and were of younger age than for their non-comorbid and older counterparts (p<0.05). The prevalence rates were significantly higher for non-Hispanic Blacks and male beneficiaries than for non-Hispanic Whites and female beneficiaries, respectively (p<0.05).

Conclusions

This patient population had higher epilepsy incidence and prevalence compared with the general US population. These differences may be at least in part attributable to their low socioeconomic status.

Gender-related protection from or vulnerability to severe CNS diseases: gonado-structural and/or gonado-activational? A meta-analysis of relevant epidemiological studies

BACKGROUND

A vast scientific literature has dealt with gender-specific risk for brain disorder. That field is evolving toward a consensus to the effect that the estrogen hormone family is outstandingly and uniquely neuroprotective. However, the epidemiology relevant to this general outlook remains piecemeal.

METHOD

The present investigation strategically formats the relevant epidemiological findings around the world in order to quantitatively meta-analyze gender ratio of risk for a variety of relevant severe central nervous system (CNS) diseases at all three gonadal stages of the life cycle, pre pubertal, post adolescent/pre menopausal, and post menopausal.

RESULTS

The data quantitatively establish that (1) no single epidemiological study should be cited as evidence of gender-specific neuroprotection against the most common severe CNS diseases because the gender-specific risk ratios are contradictory from one study to the other; (2) risk for severe CNS disease is indeed significantly gender-specific, but either gender can be protected: it depends on the disease, not at all on the age bracket.

CONCLUSION

Our assay of gender-specific risk for severe brain disease around the world has not been able to support the idea according to which any one gender-prevalent gonadal steroid hormone dominates as a neuroprotective agent at natural concentrations.

Mapping of cognitive functions in chronic intractable epilepsy: Role of fMRI

Background:

Functional magnetic resonance imaging (fMRI), a non-invasive technique with high spatial resolution and blood oxygen level dependent (BOLD) contrast, has been applied to localize and map cognitive functions in the clinical condition of chronic intractable epilepsy.

Purpose:

fMRI was used to map the language and memory network in patients of chronic intractable epilepsy pre- and post-surgery.

Materials and Methods:

After obtaining approval from the institutional ethics committee, six patients with intractable epilepsy with an equal number of age-matched controls were recruited in the study. A 1.5 T MR scanner with 12-channel head coil, integrated with audio-visual fMRI accessories was used. Echo planar imaging sequence was used for BOLD studies. There were two sessions in TLE (pre- and post-surgery).

Results:

In TLE patients, BOLD activation increased post-surgery in comparison of pre-surgery in inferior frontal gyrus (IFG), middle frontal gyrus (MFG), and superior temporal gyrus (STG), during semantic lexical, judgment, comprehension, and semantic memory tasks.

Conclusion:

Functional MRI is useful to study the basic concepts related to language and memory lateralization in TLE and guide surgeons for preservation of important brain areas during ATLR. This will help in understanding future directions for the diagnosis and treatment of such disease.

Epilepsy: Indian perspective

There are 50 million people living with epilepsy worldwide, and most of them reside in developing countries. About 10 million persons with epilepsy are there in India. Many people with active epilepsy do not receive appropriate treatment for their condition, leading to large treatment gap. The lack of knowledge of antiepileptic drugs, poverty, cultural beliefs, stigma, poor health infrastructure, and shortage of trained professionals contribute for the treatment gap. Infectious diseases play an important role in seizures and long-term burden causing both new-onset epilepsy and status epilepticus. Proper education and appropriate health care services can make tremendous change in a country like India. There have been many original researches in various aspects of epilepsy across India. Some of the geographically specific epilepsies occur only in certain regions of our country which have been highlighted by authors. Even the pre-surgical evaluation and epilepsy surgery in patients with drug-resistant epilepsy is available in many centers in our country. This article attempts to provide a complete preview of epilepsy in India.

Low seroprevalence of systemic cysticercosis among patients with epilepsy in Kerala--South India

PURPOSE

Neurocysticercosis (NCC) is considered to be rare in Kerala state, India, although it is an important cause of epilepsy in many other parts of India. Our objective was to test this notion by determining the seroprevalence of cysticercosis (CC) in an unselected sample of persons with epilepsy and comparing it to that of persons without epilepsy living in Kerala.

METHODS

Individuals with active epilepsy (AE) who had never resided outside Kerala state for more than one month and were attending our center for epilepsy care constituted the cases. Sex-matched persons without epilepsy who had never resided outside Kerala state for more than one month constituted the controls. The demographic details, occupation, and food habits (for the cases and controls), as well as clinical characteristics and imaging (for cases only) were recorded. Sera separated from blood drawn by venipuncture from the cases and controls were assayed for cysticercal antibodies by enzyme-linked immunoelectrotransfer blot (EITB).

RESULTS

Of the 80 persons with AE, 12 were seropositive for cysticercus antibodies (15%; 95% CI: 8.8-24.4); among the 68 controls, 7 were seropositive (10.3%; 95% CI: 5.1-19.8). The odds ratio (OR) for seropositivity in the epilepsy group (1.54) was not statistically significant (95% CI: 0.6-4.2). Among the 69 patients who had a brain computed tomography (CT) scan or magnetic resonance imaging (MRI), none had features diagnostic of NCC. Gender, diet (vegetarian vs non-vegetarian, consumption of raw vegetables), drinking water status (clean vs unclean), residence (rural vs urban), exposure to manure, and animal rearing including pigs did not have any association with seropositivity.

CONCLUSION

Among the residents of Kerala, most epilepsy is not related to cysticercosis.

Multicenter transversal two-phase study to determine a national prevalence of epilepsy in Algeria

BACKGROUND/AIMS

The prevalence of epilepsy in Algeria is unknown. The aims of this multicenter transversal study were to determine the national prevalence and clinical characteristics of epilepsy in the Algerian population.

METHODS

This two-phase study was conducted in 5 circumscriptions and included 8,046 subjects aged over 2 months who attended the randomly selected public and private primary care clinics. In the phase 1 study, a questionnaire was submitted to the sample of patients. In the phase 2 study, all potentially epileptic people were examined by neurologists and a second questionnaire was submitted, eventually assessed by appropriate investigations.

RESULTS

Sixty-seven patients were identified as having active epilepsy, giving a crude prevalence ratio of 8.32 per 1,000 (95% CI, 6.34-10.3) and an age-adjusted prevalence ratio of 8.9 per 1,000. The highest age-specific ratio was found in patients aged 10-19 years (16.92 per 1,000). Generalized seizures (68.7%) were more common than partial seizures (29.8%). Perinatal injuries were the major leading putative causes (11.9%).

CONCLUSION

The prevalence of epilepsy of 8.32 determined in this study is relatively high. These results provide new epidemiological data and suggest that epilepsy remains an important public health issue to consider in Algeria.

Active epilepsy as indicator of neurocysticercosis in rural northwest India

Objective. To determine the contribution of neurocysticercosis as a cause for active epilepsy and to establish Neurocysticercosis as major definable risk of epilepsy in our setup. Methods. We conducted a door-to-door survey of 2,209 individuals of Bhore Pind and Bhore Kullian villages in Chattah zone of district Jammu (Jumma and Kashmir, Northwest India) to identify patients with symptomatic epilepsy. Patients with active epilepsy were investigated with neuroimaging techniques to establish diagnosis of NCC (neurocysticercosis). Results. Among 25 patients with epilepsy 10(40%) had CT/MR evidence of past or recent NCC infection. This gave us the point prevalence of 4.5/1000 for Neurocysticercosis in our study population. Interpretation. The study shows a high prevalence of NCC accounting for symptomatic epilepsy in our part of India.

Neuroepidemiology of epilepsy in northwest India

BACKROUND

Epilepsy has a complex etiology characterised by recurring seizures.

PURPOSE

To study clinical profile of epilepsy patients with reference to type of epilepsy in northwest India. No previous Indian study has reported relative incidence of various types of seizures with reference to type of epilepsy.

METHODS

Data of 400 epilepsy patients (200 idiopathic and 200 symptomatic) was collected for their clinical characteristics. The classification of epilepsy into idiopathic and symptomatic types was done on the basis of findings of EEG, CT scan and MRI tests.

RESULTS

The age of onset of seizures was less than 15 years in only one third of the total patients. The number of non-vegetarians was higher in SE (68.5%) than IE (58%). The male to female ratio was significantly higher (1.33:1 in IE and 1.47:1 in SE). No difference was seen for place of residence (urban vs rural) patients with epilepsy (PWE). The majority of patients (58.5% of symptomatic and 52.8% idiopathic) though reported no triggering factors, yet many of them, when questioned, had held supernatural powers to be the cause of the disease. Sleep deprivation was reported as a major triggering factor by 28.5% of idiopathic epilepsy (IE) and 25% of symptomatic epilepsy (SE) patients. The incidence of mental retardation (1.25%) and behavioral disorders (7%) was found to be relatively low. Loss of memory was reported in 46% of IE and 43.5% of SE and poor scholastic performance in 23% of IE and 16.5% of SE. A positive history was recorded in 11% first-degree relatives and 4% second-degree relatives. Generalized seizures were more common in IE patients (67.5%), while partial seizures with and without secondary generalization (50.5%), and generalized seizures (49.5%) were equally common in SE.

CONCLUSIONS

The study demonstrates differences in the type of seizures between idiopathic and symptomatic epilepsies and not other demographic, clinical and psycho-social traits. The males were found to have higher risk of epilepsy than females. The epidemiological characteristics of epileptics show variations across populations and also within population.

The descriptive epidemiology of epilepsy-a review

Epilepsy is a chronic disease experienced by millions and a cause of substantial morbidity and mortality. This review summarizes prevalence and incidence studies of epilepsy that provided a clear definition of epilepsy and could be age-adjusted: requirements if comparisons across studies are to be made. Although few exceptions, age-adjusted prevalence estimates from record-based studies (2.7-17.6 per 1000), are lower than those from door-to-door surveys (2.2-41.0 per 1000). Age-adjusted incidence ranged from 16 to 51 per 100,000, with one exception in Chile, where incidence was 111 per 100,000. Variation in reported prevalence and incidence may be related to factors such as access to health care, regional environmental exposures, or socioeconomic status. A higher proportion of epilepsy characterized by generalized seizures was reported in most prevalence studies. Epilepsy characterized by partial seizures accounted for 20-66% of incident epilepsies. Virtually all prevalence and incidence studies report a preponderance of seizures of unknown cause. Additional prevalence studies are needed in regions where data does not exist, and additional incidence studies in all regions. Interpretation of differences in prevalence and incidence will require understanding of the role of cultural, social and economic factors influencing epilepsy and its care.

Epidemiology, aetiology, and clinical management of epilepsy in Asia: a systematic review

Epilepsy is a significant, but often underappreciated, health problem in Asia. Here, we systematically review the literature on epidemiology, aetiology, and management of epilepsy in 23 Asian countries. Prevalence estimates are available for only 11 countries from door-to-door surveys and are generally low. Figures for annual incidence in China and India are similar to those in the USA and Europe but lower than those reported from Africa and Latin America. There is a peak in incidence and prevalence in childhood, but a second peak in elderly people, as seen in developed countries, has not been documented. The main causes are head injuries, cerebrovascular disease, CNS infections, and birth trauma. Availability of epilepsy care depends largely on economic factors. Imaging and neurophysiological facilities are available in most countries, but often only in urban centres. Costly drugs, a large treatment gap, limited epilepsy surgery, and negative public attitude to epilepsy are other notable features of management in Asia. An understanding of the psychosocial, cultural, economic, organisational, and political factors influencing epilepsy causation, management, and outcome should be of high priority for future investigations.

The prevalence of epilepsy in the Zay Society, Ethiopia--an area of high prevalence

Very high prevalence rates of epilepsy have been found in some developing countries. The Zay Society of Ethiopia was screened for epilepsy during a door-to-door survey and after neurological assessment, a prevalence of 29.5/1000 was found. Almost all the cases had primary generalised epilepsy in contrast to the predominance of partial epilepsy found elsewhere. Due to its historical isolation, epilepsy genes may have become widely disseminated throughout the Zay Society, accounting for the elevated prevalence.

Prevalence and Characteristics of Epilepsy in the Aeolian Islands

PURPOSE

To estimate the prevalence and define the clinical characteristics of epileptic disorders in the 13,431 residents of the Sicilian Aeolian archipelago, on June 1, 1999.

METHODS

All established or suspected cases were identified by the neurologists of our working group from available medical information sources. Possible epilepsy cases were then evaluated by the epileptologists by using a standardized questionnaire. The patients were further reviewed by the whole research team to confirm the clinical diagnosis. For a more detailed syndromic definition, some patients underwent EEG or neuroradiologic investigations or both.

RESULTS

The crude point prevalence rate of active epilepsy was 3.13 (95% confidence interval, 2.2-4.2). The prevalence rate age-adjusted to the 2001 Italian population was 3.01. Females had a slightly higher prevalence rate than did males. The highest age-specific prevalence was found in patients aged 5 to 14 years (5.05) and in those aged 65 to 74 years (5.41). Partial seizures with or without secondary generalization were more common (61.7%) than were generalized seizures. Eighty-three percent of cases had symptomatic or cryptogenic localization-related epilepsies, and 8.5% had idiopathic (generalized or partial) epilepsies. Epilepsy was unclassified in 8.5% of cases.

CONCLUSIONS

The prevalence of active epilepsy in the Aeolian islands is lower than that in other developed areas, including northern Italy, but is similar to that in Sicily. Partial seizures were the most common type, and localization-related symptomatic epilepsies were the largest syndromic category.

Genetic liability to epilepsy in Kerala State, India

BACKGROUND

Familial clustering is common in epilepsies, but pedigree patterns suggest a multi-factorial inheritance. Genetic liability for multi-factorial inheritance is population specific and such data are not available for the population of Kerala or other states in south India.

OBJECTIVES

In this study, we have attempted to determine the genetic liability to epilepsy based on an adult population of this state.

MATERIAL AND METHODS

Pedigrees were recorded for probands who reported to the Kerala Registry of Epilepsy and Pregnancy. In order to obtain a genetically matched sample for comparison and estimation of empiric risks, we have used the family history of the spouse except when the spouse was proband's relative. The ILAE criteria were followed for diagnosis and classification of epilepsy.

RESULTS

Data were collected on 18,419 family members of 505 probands with epilepsy (82 men and 423 women) and 10,231 family members of spouses (control). The frequency of epilepsy in first and second-degree relatives of the spouses was comparable to the population frequency (0.5%), justifying the use of this sample as control. Positive family history was observed in 22.2% of probands and 8.24% of controls (Odd's Ratio 3.2, 95% Confidence Interval 2.12-4.73). An affected first-degree relative was observed in 7.5% of probands. The corresponding figure for GE, LRE and other epileptic syndromes were 10.2%, 5.8% and 5.12%, respectively. The segregation ratio for Juvenile Myoclonic Epilepsy (JME) (1:19) was higher than that for other types of Generalized Epilepsy (GE) (1:24) and Localization Related Epilepsy (LRE) (1:52). Prevalence of epilepsy among the first-degree relatives (1.96%) was greater than the square root of the population frequency (0.51%) and was higher than that for second-degree (1.24%) and third-degree (0.64%) relatives for the probands. Probands had higher parental consanguinity (13.07%) compared to controls (6.64%). The above factors support a complex inheritance. Genetic liability to epilepsy (heritability) is greater for GE (0.6) and significantly higher for JME (0.7) compared to LRE (0.4). A limitation of this study is that the inferences are based on a predominantly adult female proband sample but no gender specific differences were identified.

CONCLUSIONS

The observations of this study indicate complex inheritance and the liability values are useful for genetic counseling in the local population. Further studies involving more individuals from younger age group and male gender are envisaged.

Treatments and perceptions of epilepsy in Kashmir and the United States: a cross-cultural analysis

Treatments and perceptions of epilepsy have been found to vary across cultures. This study draws on a comparison of two patient samples, one from the United States (n=28), the other from Kashmir (n=29), to gauge the similarities and differences in social perceptions of epilepsy, attitudes toward conventional and alternative treatments, practice of conventional and alternative treatments, and selected quality-of-life issues. While both the Kashmiri and American patients interviewed were prescribed a similar regimen of traditional antiepileptic drugs, a wider range of drugs and treatments were available to and used by the latter. The use of adjunctive spiritual therapies was more prevalent in the Kashmiri sample, and the use of alternative, nonpharmacological therapies was more prevalent in the American sample. Quality of life for the Kashmiri patients sampled was found to be poorer in terms of educational and occupational opportunities, feelings of stigmatization, and openness with others about the illness. Although the two patient populations interviewed differed in their access to resources and approaches to the disorder, both samples were found to be similar overall in many attitudes and practices relating to epilepsy and its treatment.

Urban prevalence of epilepsy: populational study in São José do Rio Preto, a medium-sized city in Brazil

The aim of this study was to determine the prevalence of epilepsy in the urban population of São José do Rio Preto. This is a medium-sized city of 336000 inhabitants, located in the northwest of the state of São Paulo, Brazil. METHOD: A crosssectional epidemiological investigation with a randomized sample was performed in two phases, a screening phase and a confirmation of the diagnosis phase. The gold standard was a clinical investigation and neurological examination. The chi-square test was used in analysis of the results and p-value value < 0.05 was considered significant. Prevalence was calculated with 95% confidence interval. RESULTS: The study sample size was 17293 individuals, with distributions of gender, age, and race similar to the general population. The prevalence per 1000 inhabitants of epilepsy was 18.6, of these 8.2 were active, defined as at least one seizure within the last two years. The prevalence per 1000 inhabitants for the age groups (years) was 4.9 (04), 11.7 (514), 20.3 (1564) and 32.8 (65 or over). CONCLUSION: Prevalence of both accumulated and active epilepsy was elevated, comparable to other developing nations, in particular those of Latin America. However, the prevalence of epilepsy in childhood was low, whilst in aged individuals it was high similar to industrialized nations.

Epidemiology of epilepsy in India

The article briefly reviews literature pertinent to the incidence, prevalence, prognosis, etiology, and treatment gap of epilepsy in India. Despite defective methodology, Indian studies have shown prevalence rates comparable with those from other countries. No incidence studies exist. Prognosis for those with epilepsy is worse in developing countries. The role of infection, especially neurocysticercosis, in the etiology of epilepsy has still to be fully worked out, as must the relative contributions of the other known etiological factors. Neuroimaging is needed to calculate attributable risk. Reasons for the treatment gap are discussed briefly, pointing out that in India, people seek alternative forms of treatment concurrently. The occurrence and effects of stigma are mentioned. The article ends with the author's opinion on how and where the epidemiology of epilepsy should proceed in the future.

The natural history of epilepsy in the era of new antiepileptic drugs and surgical treatment

PURPOSE

To review the factors influencing prognosis of epilepsy in this era of antiepileptic drugs and surgical treatment.

METHODS

Systematic review of peer-reviewed literature.

RESULTS

The prognosis depends on many factors; aetiology, age of onset, number of seizures at onset, the natural history of the condition, and the influence of treatment. However, between 70 and 80% of people developing epilepsy will go into long-term remission, usually within the first 5 years.

DISCUSSION

Prognosis in epilepsy is the prospect of attaining complete seizure freedom once a pattern of recurrent epileptic seizures has been established. Well-designed prospective cohort studies using standard outcome measures need to be conducted, especially in non-Western cultures.

Evidence-based medicine: neuroimaging of seizures

Evidence-based medicine is useful in epilepsy and neuroimaging (Figs. 1 and 2). An understanding of the pretest probability suggests that focal neurologic deficits are important in predicting the outcome of neuroimaging examinations. In cases of nonacute symptomatic seizures, confusion and postictal deficits should prompt MR evaluation. In remote symptomatic seizures, MR imaging should be performed in a child with unexplained cognitive or motor delays or a child less than 1 year of age. Patients with partial seizures, abnormal EEG, or generalized epilepsy also should be imaged. Acute seizures should be imaged with CT to exclude hemorrhage and because of the availability and speed of the modality. Ictal SPECT is the best neuroimaging examination to localize seizure activity. MR imaging can offer prediction of surgical outcome and may hold promise in the future for dimensional localization of seizure focus. Evidence-based medicine can only work if there is physician communication. The pretest probability is helpful only when an accurate history is provided to the consulting physician. This field will flourish if physicians can develop accurate methods of collating information and reporting it in a timely fashion in the literature.

The prevalence of epilepsy amongst school children in Izmir, Turkey

OBJECTIVE

The aim of this study was to assess the prevalence of epilepsy among school children between the ages of 7-17 in Izmir province, in Turkey.

METHODS

A cross sectional study was conducted. Sample size is calculated as 4654, from the target population of 420054 students. A stratified random sampling technique was used to select the schools located in Izmir Metropolitan area. For the 130 (2.8%) students whose families gave a positive 'epilepsy history' a telephone interview was conducted in order to verify the diagnosis and to evaluate a etiological factors.

RESULTS

Response rate was 90.5% (4216 students). Out of the 130 students who had a positive epilepsy history, 47 (36.2%) were accepted as epilepsy 'cases'. The crude prevalence rates for females, males and the total study population were found respectively to the 11.3, 11.1 and 11.2 per thousand. Prevalence of active epilepsy rates for females, males and total study population were found respectively to be 4.5, 7.0 and 5.6 per thousand.

CONCLUSION

The prevalence of epilepsy is higher in school-age children in Izmir province compared to that in developed countries.

Prevalence, knowledge, attitude, and practice of epilepsy in Kerala, South India

PURPOSE

To ascertain the prevalence and pattern of epilepsy and to characterize and quantify knowledge, attitude, and practice (KAP) toward epilepsy among the people of the state of Kerala, which is distinguished from the rest of India by a high level of literacy and health awareness of its population.

METHODS

We conducted a door-to-door survey covering the entire population of 238,102 people residing in 43,681 households in a semiurban area of central Kerala. The screening questionnaire administered by medical social workers had a sensitivity of 100% for identifying persons with epilepsy. Neurologists examined all the individuals suspected of having epilepsy. We evaluated KAP toward epilepsy among 1,118 subjects (439 males and 679 females; mean age, 33.3 years; age range, 15-85 years) from households without epilepsy in the study area.

RESULTS

Through a three-phased survey, we ascertained 1,175 cases (616 males and 559 females) with active epilepsy, providing a crude point prevalence ratio of 4.9 cases per 1,000 people and an age-adjusted prevalence ratio of 4.7 cases per 1,000 population. The highest age-specific prevalence rate of 6.5 per 1,000 occurred in the 10- to 19-year-old age group. Sex-specific prevalence rates did not significantly differ. The proportion of generalized and localization-related epilepsies was 58.8% and 30.6%, respectively. Ninety-nine percent of the KAP respondents had read or heard about epilepsy. Thirty-one percent and 27% thought epilepsy was a hereditary disorder and a form of insanity, respectively. About 40% of the respondents felt that individuals with epilepsy could not be properly educated or employed. Eleven percent would object to their children having contact with epileptic children.

CONCLUSIONS

The prevalence and pattern of epilepsy in central Kerala, South India, do not differ from that of developed countries. Although the awareness of epilepsy among the people of Kerala was comparable to that of developed countries, the attitudes were much more negative. The need for educating the people of Kerala on epilepsy and for incorporating an adequate knowledge of epilepsy in the school curricula cannot be overemphasized.
