Abstract
BACKGROUND: Studies on prevalence of epilepsy in Nigeria yielded figures ranging between 3.1 and 37 per 1000, giving one of the widest variations in prevalence of epilepsy world over. In order to accurately estimate clinical and public health impacts of epilepsy in Nigeria, robust and reliable epidemiological data are required for an appropriate estimation of logistical, economical, and social impacts of epilepsy. OBJECTIVE: The objectives of the study were to determine, using meta-analysis, the prevalence of epilepsy by pooling data from community-based door-to-door surveys conducted in various parts of Nigeria, explore the existing variation in prevalence of epilepsy in Nigeria along geopolitical regions and settlement setting of the country, and then evaluate the burden of epilepsy in Nigeria. METHODS: Prevalence estimates were derived from a random effects meta-analysis of observational studies reporting the prevalence of epilepsy in Nigeria. The derived estimate for the prevalence of epilepsy was applied to the total populations in Nigeria to give an estimated burden of epilepsy in Nigeria. RESULT: Nine community-based door-to-door surveys, with quality data from different regions in Nigeria, were included. I-squared (I2) heterogeneity was 88.5%. Random effects model (REM) estimate of overall prevalence of epilepsy from the studies was 8 per 1000 (95% confidence interval (95% CI): 6-10). The prevalence was highest (11 per 1000) in the south western part of the country. It was also higher among the rural (15 per 1000 people) than the urban (6 per 1000) dwellers. The burden of epilepsy in Nigeria, based on the prevalence estimate was 1,280,000 persons (95% CI: 960,000-1,600,000 persons). CONCLUSION: In Nigeria, the estimated prevalence of epilepsy is 8 per 1000 people indicating a substantial burden of the disease in the country.
