AI Insight
A multi-institutional study using human brain organoids (lab-grown tissue models) examined the effects of valproate, a commonly prescribed antiepileptic drug, on early brain development over a 30-day exposure period. The research found that valproate disrupts early brain growth processes, providing new mechanistic insights into why the drug is associated with increased risk of developmental disorders in children exposed in utero. The findings were published in the peer-reviewed journal Molecular Psychiatry.
Why it matters
Understanding how valproate affects early human brain development at a cellular and tissue level could inform strategies to reduce developmental risks for pregnancies where the drug is medically necessary. This research also demonstrates the utility of brain organoids as a model for studying drug teratogenicity without relying solely on animal studies.
It is known that the antiepileptic drug valproate increases the risk of developmental disorders in unborn children. A study conducted by the Karlsruhe Institute of Technology (KIT), the Heidelberg Academy of Sciences and Humanities, the University of Tübingen, and the University Heidelberg using lab-grown tissue models of the human brain gives new insights into the effects this drug has on early brain development. They open new avenues for research to mitigate the risk during pregnancy. The study has been published in Molecular Psychiatry.
