Epilepsy prevalence in a rural area in Istanbul.

This study is a field study with cross-section and case control conducted in the Kucukcekmece Region of Istanbul between June 1999 and February 2000. Four hundred and ninety three dwellings selected by a simple random sampling method were visited. From a population of 2187, 58 people, after filling in a questionnaire were suspected to have epilepsy. Following an interview, neurological examination and an electroencephalogram (EEG) 17 were diagnosed as having epilepsy. Lifetime epilepsy prevalence was 0.8%. 41.2% of the 17 epilepsy cases had partial epilepsy ( n= 7), 47.0% had generalized (n = 8) and in 11.8% seizures could not be classified ( n= 2). The risk factors for epilepsy in the control group ( n= 125) from the same region and those with epilepsy were investigated by means of logistic regression analyses. Educational status (odds ratio : 1.82, 95% confidence interval : 1.13-2.94; P= 0.01), profession (OR : 0.76, 95% CI : 0.60-0.97; P= 0.03), history of epilepsy in the family (OR : 0.67, 95% CI : 0.47-0.94; P= 0.02) were determined to be correlated with epilepsy. The results have drawn attention to the fact that individuals should be informed about epilepsy.
