Neuroepidemiology of epilepsy in northwest India

Epidemiological Survey of Neurological Diseases in a Tribal Population Cluster in Gujarat

Background:

There are few community-based neuroepidemiological studies based in tribal communities. This cross-sectional community-based study explored the prevalence rates of neurological disorders in the tribal region of Kaparada in Gujarat.

Methodology:

A two-stage methodology was used. Door-to-door surveys were conducted in the villages of Moti Vahiyal, Arnai, and Chavshala in Kaparada taluka in the Valsad district. Trained volunteers administered a questionnaire that assessed demographic details and common neurological symptoms in children and adults. Data were obtained from 8217 individuals from 1464 households using the questionnaire in stage 1. A number of 615 individuals reported at least one symptom. In stage 2, a team of neurologists conducted a medical camp to assess those “screened in” for neurological disorders.

Results:

The crude prevalence rate for neurological disorders in general was found to be 2592.19/100,000. The prevalence rates for lower motor neuron diseases were highest (1010.1), and the rates of epilepsy, movement disorders, stroke, vertigo, headaches, upper motor neuron diseases, and mental and behavioral disorders were found to be 255.6, 133.9, 109.53, 170.38, 511.4, 109.53, and 292.08/100,000, respectively. Age- and sex-specific rates and patterns varied for different disorders.

Conclusion:

The prevalence rates of most disorders were found to be lower than those reported elsewhere, but age and sex prevalence patterns were similar to existing research. Challenges in conducting such a study in a remote population are discussed.

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.

Profile of epilepsy in a regional hospital in Al qassim, saudi arabia

INTRODUCTION

Epilepsy is a diverse set of chronic neurological disorders characterized by seizures. It is one of the most common of the serious neurological disorders. About 3% of people will be diagnosed with epilepsy at some time in their lives.

OBJECTIVES

We aimed to address the commonest types of seizures, their aetiologies, EEG and neuroimaging results and prognosis of patients presented to neurology services of the King Fahad Specialist Hospital- AlQassim (KFSH).

METHODOLOGY

In this retrospective epidemiological study we investigated the medical records of patients with epilepsy, who attended the neurology services of KFSH, during the study period (26/10/2011-26/4/2012).

RESULTS

The study included 341 patients; 189 (55.4%) males and 152 (44.6%) females. Their ages ranged between 12 and 85 years (mean ± SD = 31±16.9). The majority of patients had Generalised Tonic Clonic Seizures (76.2%), followed by Complex Partial Seizures (7.6%). 73% of our patients had idiopathic epilepsy. The commonest causes for symptomatic epilepsy were Cerebro Vascular Accidents and Head trauma. Hemiplegia, mental retardation and psychiatric illness were the commonest comorbidity. 69.3% of patients had controlled seizures. Patients with idiopathic epilepsy were significantly controlled than patients with symptomatic epilepsy (P=0.01), and those using one Anti Epileptic Drug were significantly controlled compared to patients using polytherapy (P=0.0001) there was no significant relation between controlled seizure and duration of illness or hospitalization or EEG changes.

CONCLUSION

Seizure types, aetiology, drug therapy, Comorbidities and outcome in a tertiary care hospital in Saudi Arabia are similar to previous local and international studies. 35.3% of patients were hospitalized, higher rates than previous studies. Seizure control was better in generalized seizures and idiopathic epilepsy compared to complex partial seizures or partial seizures with secondary generalization and symptomatic epilepsy.
