Developmental Delay in Children Exposed During Pregnancy to Either Lamotrigine,Sodium Valproate, or Carbamazepine
This study is investigating the neurodevelopmental effects of prenatal exposure to lamotrigine (LTG), sodium valproate (VPA), or carbamazepine (CBZ) monotherapies. The hypotheses to be tested include:
- Exposure during pregnancy to CBZ, LTG, and VPA, each as monotherapy, is associated with developmental delay with or without signs of autism.
- Exposure to each drug (CBZ, LTG, and VPA) as monotherapy is associated with an increased rate of occurrence of major malformations.
- The child with major malformations is more likely to have developmental delay with or without signs of autism than the child who does not have major malformations.
- The occurrence of adaptive behavior outcomes will show a dose-response relationship with the dose of medication taken by the mother in the first trimester.
The study population includes children 36-83 months of age who were exposed throughout gestation to one of the three drugs of interest, as treatment for maternal seizure disorder.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Developmental Delay in Children Exposed During Pregnancy to Either Lamotrigine, Sodium Valproate, or Carbamazepine|
- Adaptive Behavior Scores [ Time Frame: 36-83 months of age ] [ Designated as safety issue: No ]Measures of each child's Adaptive Behavior scores as assessed by the Vineland-II Adaptive Behavior Scales, collected when the child was between 36 and 83 months of age.
- Presence/Absence of Major Malformations [ Time Frame: 36-83 months of age ] [ Designated as safety issue: No ]Based on interview with mother and review of medical records, determination is made as to whether or not the child had any major malformations at birth.
