Randomized Controlled Trial
Prevalence of epilepsy in the 15 years and older in Benin: a door-to-door nationwide survey.
Estimate the prevalence of epilepsy in the 15 years and older in Benin. ⋯ This nationwide study is the first in West Africa. It provides a low prevalence of epilepsy in Benin compared to previous studies performed in this country and in neighbouring countries. Restricted-area studies are often motivated by the presence of specific risk factors and could overestimate the prevalence, while large-scale studies could underestimate other subtle forms of epilepsy.

It is unknown whether white matter abnormalities exist in childhood absence epilepsy (CAE), a syndrome of idiopathic epilepsy (IGE). Diffusion tensor imaging (DTI) can noninvasively quantify white matter integrity. This study used DTI to investigate abnormal changes in white matter of untreated CAE patients. ⋯ The results showed white matter integrity impairment in the basal ganglia-thalamocortical circuit of drug-naïve CAE patients. These abnormalities in white matter may be related to increased cortical excitability and cause cognitive, linguistic, and behavioral/emotional deficits both during and between seizures.
