AbstractWe aimed to characterize the seizure pattern during pregnancy in a large cohort of women with epilepsy (WWE) and identify possible predictors of seizure relapse during pregnancy. We recorded the antiepileptic drug (AED) use and seizure frequency for WWE during the prepregnancy month and pregnancy. The seizure profile was correlated with the clinical details and seizure type as abstracted from the clinical records maintained in the registry. Of the 1,297 pregnancies in WWE with complete seizure data, 47.8% were seizure-free during pregnancy. Seizure relapse was highest during the three peripartum days. Women with partial seizures-had higher risk of relapse (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.2-2.0) than those with generalized seizures. They had two peaks of seizure relapse (second to third month and sixth month). Those with generalized seizures had one peak at first trimester. Those who were on polytherapy had increased risk of seizures (OR 2.98, 95% CI 2.3-3.9) when compared to those on monotherapy. Those who had seizures in the prepregnancy month had higher risk (OR 15, 95% CI 9-25.1) of seizures during pregnancy when compared to those who were seizure-free during that period. On multiple logistic regression, prepregnancy seizure was the most important predictor of seizures during pregnancy.Wiley Periodicals, Inc. © 2012 International League Against Epilepsy.
