    Abstract:
    When compared to that of industralised countries, the prevalence of epilepsy in developing countries has generally been found to be higher and in some areas extremely high rates of up to 57 cases per 1000 inhabitants have been reported. The reasons for this difference are still widely unknown and detailed epidemiological as well as clinical data are scarce, especially from rural Africa. The present study was conducted in western Uganda, in an area of high epilepsy prevalence, known to be endemic for onchocerciasis. The seizures of all 91 epilepsy patients diagnosed in this area over the period of two years were classified according to the criteria of the International League against Epilepsy. Based on seizure description alone, the predominant seizure was classified as generalised in 57 patients (63%), as partial in 22 (24%) and unclassified in 12 (13%). An EEG record was analysed in 55 out of 91 patients, showing focal epileptiform activity (EA) in 12, multifocal EA in 9 and primarily generalised EA in 6 patients. When in addition to clinical information, the EEG results in the 27 patients with EA were taken in consideration for seizure classification, the proportion of partial seizures increased to 78% (n = 21); inversely the proportion of generalised seizures fell to 22% (n = 6). The predominance of partial seizures would be compatible with a localised brain lesion as a frequent cause for epileptic seizures in the study area. The findings further corroborate recent observations from several African countries of an association between epilepsy and onchocerciasis.
