    The first serious signal was in 1982

    The first report on 9 cases à of a specific malformation (spinabifida) appeared in the Lancet on October 23, 1982. I signed this letter (E.Robert) that indicated a risk ratio of 30 for mothers taking valproate. Following this alarm, hundreds of publications confirmed the risk, and others (other malformations, and autism know from 2000). A correct warning was given to women in childbearing age in 2015 in France, after the first lawsuits were initiated.
