The study included self-reported data from 106,935 pregnancies.
Seven hundred eleven women reported having epilepsy, and 45.9 % of them were using antiepileptic drugs (AEDs). Compared to the reference group, self-reported eating disorders and depression were increased in the untreated epilepsy group before pregnancy. Both AED-treated and untreated women with epilepsy reported higher depression scores as assessed by the Hopkins Symptom Checklist, and the Lifetime Major Depression scale was increased in AED-treated women. Antiepileptic drug treatment was linked to low income (27.4 % vs. 18.4 % , p < 0.001) and no income (5.5 % vs. 2.6 % , p = 0.001). Low educational level was associated with epilepsy in AED-treated and untreated women (50.5 % , p < 0.001 and 46.9 % , p < 0.001 vs. 32.2 % ), as was unemployment due to disability (7.9 % , p < 0.001 and 6.5 % , p < 0.001 vs. 1.5 % ) and single parenting (4.4 % , p = 0.016 and 4.5 % , p = 0.007 vs. 2.4 % ). No difference was found for smoking, alcohol use, or narcotic use.
Symptoms of depression were associated with epilepsy both during and before pregnancy. Epilepsy was linked to eating disorders before pregnancy. Unemployment, single parenting, and low educational level were linked to epilepsy in young pregnant females. Efforts aiming at treatment and screening for psychiatric comorbidity in pregnant women with epilepsy are important in the follow-up of these patients.
