[Epidemiology of epilepsy in sub-Saharan Africa: a review].

Epilepsy is, above all tropical, moreover, very african in its frequency and gravity. Data on the prevalence of epilepsy shows it to be two or three times more prevalent in tropical zones than in industrialized countries in non tropical areas, however it is rare to find data on the incidence and prognosis of epilepsy in sub-Saharan Africa. It is difficult to determine the relative contribution of each of the causes of epilepsy. Only a few case-control studies have been carried out in sub-Saharan Africa. Infectious diseases, in particular parasitic diseases such as neurocysticercosis or cerebral malaria, seem to be the cause of the majority of the cases of epilepsy. However it is necessary to do additional epidemiological studies to determine the etiologies of epilepsy more precisely in sub-Saharan Africa.
