Impaired executive functioning in children of women with epilepsy

While neurodevelopmental symptoms are often seen in children of mothers with epilepsy, research specifically addressing executive function (EF) in this population is limited. This study aims to investigate EF in children of mothers with epilepsy, both with and without fetal exposure to anti-seizure medications, compared to typically developing children whose mothers do not have epilepsy.

We evaluated EF in children aged 8 to 17 years born to mothers with clinically validated diagnoses of epilepsy, using the Behavior Rating Inventory of Executive Function completed by the mothers. The results were then compared to a typically developing control group at the same age living in the same geographic area.

The results showed significantly higher levels of EF problems in children of mothers with epilepsy who were exposed (p = 0.005, d = 0.63), and unexposed (p = 0.001, d = 0.74) to anti-seizure medications during pregnancy, compared to typically developing children. There was no significant difference in EF problems between the exposed and unexposed groups. These findings remained statistically significant after adjusting for mothers' education levels, and when excluding participants exposed to valproate during pregnancy.

This study highlights the increased risk of EF problems in children of mothers with epilepsy, independent of exposure to anti-seizure medications. Findings underscore the importance of continuous monitoring of EF in these children and highlights the need for further research into the diverse factors affecting EF development in this group.
