PURPOSE: Epilepsy is highly prevalent in developing countries like Honduras, with few studies evaluating this finding. This population-based study evaluated the impact of an 8-year public health and educational intervention program in reducing symptomatic epilepsies in rural Salamá, Honduras.
METHODS: We used the capture and recapture method including review of charts, previous databases, key informants from the community, and a second house-to-house survey for epilepsy. Epilepsy incidence and prevalence day after the interventions was May 5, 2005. Residents with active epilepsy with onset after May 1997 were offered neurologic evaluation, electroencephalography, and brain tomography. New data over 8 years were compared to preintervention data from the initial baseline 1997 study utilizing prevalence ratios and confidence intervals. Other calculations utilized chi square or Fisher's exact tests.
KEY FINDINGS: Thirty-three of 36 patients with onset of active epilepsy after 1997 accepted evaluations to determine etiology. Symptomatic etiology was found in 58.3%. Neurocysticercosis (NCC) was again the most frequent cause (13.9%), followed by perinatal insults (11.1%). Epilepsy secondary to NCC was significantly reduced from 36.9% in 1997 (p = 0.02). The incidence (35.7/100,000) and prevalence (11.8/1,000) of active epilepsy were not significantly reduced when compared to the incidence (92.7/100,000) and prevalence (15.4/1,000) of active epilepsy in 1997.
SIGNIFICANCE: Our cohort appears to indicate that health and educational community interventions can reduce preventable epilepsy from NCC in a hyperendemic population in a low-resource, developing country. Plans are underway for the Honduran Government to institute this rural model countrywide.
