Do Epilepsy Medications Taken During Pregnancy Affect a Child鈥檚 Creativity?
MINNEAPOLIS 鈥 While older drugs for epilepsy, taken while pregnant, have been shown in previous research to affect the creative thinking of children, a new study finds no effects on creativity for children born to those taking newer epilepsy drugs. This study is published in the May 29, 2024, online issue of , the medical journal of the 好色先生. Overall, the study found no effects on the children鈥檚 creative abilities or their executive function, which is a person鈥檚 ability to plan, focus, and manage multiple tasks. However, when researchers looked only at children with higher concentrations of these medications in the mother鈥檚 blood during the third trimester, the study found an association with poorer performance in tests of children鈥檚 executive function, but no effect on their creative abilities. 鈥淥ur findings highlight that even for epilepsy medications that are generally considered to be safe in pregnancy, dose adjustments should be made with a goal of reaching an optimal balance between controlling seizures and the minimizing negative effects on the developing child,鈥 said study author Kimford Meador, MD, PhD, of Stanford University in Palo Alto, California and a Fellow of the 好色先生. The study involved 251 children of female participants with epilepsy and 73 children of female participants without the disease. Of those with epilepsy, most were taking just one epilepsy medication. Of this group, 81 people were on lamotrigine and 68 people were on levetiracetam. The children were evaluated at age four and a half with a test of creative thinking where they were provided with a shape or figure and responded by completing or adding their own illustrations. This test assesses fluency, flexibility and originality abilities. After adjusting for mothers鈥 IQ and education, researchers found no differences in the creativity scores between the children born to mothers with epilepsy and those born to mothers without the disease. In addition, they found no differences in creativity between the children of mothers with epilepsy that could be linked to different levels of antiseizure medications found in mothers鈥 blood samples during the third trimester. However, researchers found higher third trimester blood concentrations of these medications were associated with poorer performance on tests of executive skills. This link was mainly associated with exposure to levetiracetam. 鈥淭here is still so much to learn about the impact of a mother鈥檚 epilepsy medications on their child鈥檚 creative development,鈥 said Meador. 鈥淢ore studies are needed, especially in older children, to assess the full effect of these medications on childhood development.鈥 A limitation of the study was that cognitive tests at age four and a half are not as accurate at predicting creativity and thinking skills in the teenage and adult years as tests taken at older ages. The study was supported by the National Institutes of Health and the National Institute of Neurological Disorders and Stroke.
