Insights
Children exposed to levetiracetam (LEV) in utero show no increased risk of developmental delays by age two. LEV appears to be a safer choice for women with epilepsy (WWE) compared to sodium valproate (VPA).
Area of Science:
- Neuroscience
- Developmental Pediatrics
- Pharmacology
Background:
- Epilepsy in women of childbearing age necessitates careful medication management.
- Antiepileptic drugs (AEDs) carry potential risks for fetal development.
- Levetiracetam (LEV) and sodium valproate (VPA) are commonly used AEDs with differing safety profiles.
Purpose of the Study:
- To assess the early cognitive development of children exposed in utero to LEV.
- To compare cognitive outcomes between children exposed to LEV, VPA, and a general population control group.
- To determine if in utero LEV exposure is associated with delayed early cognitive development.
Main Methods:
- Prospective observational study of children from UK cohorts, assessed <24 months.
- Griffiths Mental Development Scale (1996) used for cognitive assessment.
- Maternal demographics and epilepsy status were collected and controlled for.
Main Results:
- Children exposed to LEV demonstrated significantly higher developmental scores than those exposed to VPA (p < 0.001).
- No significant difference in overall development was observed between LEV-exposed children and the control group (p = 0.62).
- Only 8% of LEV-exposed children had below-average scores, compared to 40% of VPA-exposed children.
Conclusions:
- In utero exposure to LEV is not associated with an increased risk of delayed early cognitive development up to 24 months.
- LEV may be a preferred AED for women with epilepsy (WWE) of childbearing age.
- These findings support the use of LEV in pregnancy when clinically indicated.
Objective:
Children born to women with epilepsy (WWE), exposed in utero to levetiracetam (LEV, n = 51), were assessed for early cognitive development and compared to children exposed to sodium valproate in utero (VPA, n = 44) and a group of children representative of the general population (n = 97).
Methods:
Children were recruited prospectively from 2 cohorts in the United Kingdom and assessed using the Griffiths Mental Development Scale (1996), aged <24 months. Information regarding maternal demographics were collected and controlled for. This is an observational study with researchers not involved in the clinical management of the WWE.
Results:
On overall developmental ability, children exposed to LEV obtained higher developmental scores when compared to children exposed to VPA (p < 0.001). When compared, children exposed to LEV did not differ from control children (p = 0.62) on overall development. Eight percent of children exposed to LEV in utero fell within the below average range (DQ score of <84), compared with 40% of children exposed to VPA. After controlling for maternal epilepsy and demographic factors using linear regression analysis, exposure to LEV in utero was not associated with outcome (p = 0.67). Conversely, when compared with VPA exposure, LEV exposure was associated with higher scores for the overall developmental quotient (p < 0.001).
Conclusion:
Children exposed to LEV in utero are not at an increased risk of delayed early cognitive development under the age of 24 months. LEV may therefore be a preferable drug choice, where appropriate, for WWE prior to and of childbearing age.
