Neurocysticercosis: a major aetiological factor of late-onset epilepsy in Madagascar.

To assess the impact of cysticercosis on public health in Madagascar, we compared patients > 15 years with late-onset epilepsy to non-epileptic controls in a matched case-control study. The association between epilepsy and cysticercosis was studied by enzyme-linked immunoelectrotransfer blot (EITB) assay for antibodies specific to Taenia solium. The EITB assay was performed on 104 pairs of sera specimens and on 95 pairs of cerebrospinal fluid (CSF) specimens.
