Abstract

Objectives: To assess the possibility that the occurrence of seizures or the use of antiepileptic drug (AED) therapy might have influenced the rate of occurrence of volunteered histories of patient-recognized depression during pregnancy in women with epilepsy.

Materials and methods: Analysis of data from 2039 pregnancies in the Raoul Wallenberg Australian Register of Antiepileptic Drugs in Pregnancy (APR) followed during pregnancy and to the end of the year after its end.

Results: Patient-recognized depression occurrence rates during pregnancy were a little lower rather than higher in seizure-affected than in seizure-free pregnancies (5.67% vs 6.41%), though higher in AED-treated than AED-untreated pregnancies (6.24% vs 5.26%; RR = 1.185, 95% CI 0.612, 2.295). Logistic regression analysis showed that carbamazepine dosage had a statistically significant relationship with a decreasing rate of patient-recognized depression occurring during pregnancy and topiramate dosage with an increasing rate.

Conclusions: Carbamazepine and topiramate both have established potentials for causing teratogenesis, and it is possible that replacement of carbamazepine with a less teratogenic AED, for example levetiracetam, might result in any subsequent depression that occurs in pregnancy being inappropriately attributed to the newly introduced agent.
