Profile of epilepsy in a developing country: a study of 1,000 patients based on the international classification.
The present prospective study undertaken in a specialized neurological center of a developing country deals with 1,000 epileptic patients classified in accordance with the International Classification. Eighty-one percent of the patients could be classified, with a lower incidence in the younger age group. Partial epilepsy was found to be far more common than generalized epilepsy (80% versus 20%). Primary generalized epilepsy was seen in 15% and secondary generalized in 5%. Partial epilepsy with elementary symptomatology was seen in 58% and complex symptomatology in 7%. Secondarily generalized seizures were seen in the remaining 15%. Primary generalized epilepsy and partial epilepsy with complex symptomatology were more common in adults. Secondary generalized epilepsy and partial epilepsy with secondarily generalized seizures were more common in children. Partial epilepsy with elementary symptomatology, however, did not vary significantly with age. The higher incidence of partial epilepsy in our patients, compared to the West, could be due to greater frequency of CNS infections and birth injuries, which are common childhood hazards in the developing countries.
