A new Danish study on nearly 700,000 babies has found that women who take the epilepsy drug valproate during pregnancy are three times more likely to have a child with some form of autism.
While earlier studies have found increased risks of birth defects associated with mothers who took the drug, the new results represent the strongest link between valproate and autism to date.
According to the U.S. Centers for Disease Control and Prevention, roughly one in 88 children have an autism spectrum disorder, which ranges from autism itself to Asperger's syndrome.
Using a large drug database, the new study tracked 656,000 children born in Denmark between 1996 and 2006 and found that about 6,600 of their mothers had epilepsy and 508 of them took valproate while pregnant.
By 2010, 4.4 percent of the children whose mothers had taken the drug were diagnosed with autism spectrum disorder, the study found. That was nearly triple the 1.5 percent of all the children studied who had been diagnosed with an autism spectrum disorder.
"For women of childbearing potential who use anti-epileptic medications, these findings must be balanced against the treatment benefits for women who require valproate for epilepsy control," researchers concluded in their report published in the April 24 issue of the Journal of the American Medical Association.
But researchers added that "because autism spectrum disorders are serious conditions with lifelong implications for affected children and their families, even a moderate increase in risk may have major health importance."
