Antidepressants in Pregnancy Linked to Autism?
New study discounts pills' link to autism, but suggests ties to ADHD
By Robert Preidt
WEDNESDAY, Aug. 27, 2014 (HealthDay News) -- There's been controversy for years over whether the use of common antidepressants by women during their pregnancies might raise the odds of mental health issues in their children.
Now, a study involving more than 13,000 children finds no rise in the risk of autism in children whose mothers used an antidepressant while pregnant, but some data suggesting a heightened risk of attention-deficit/hyperactivity disorder (ADHD) in these youngsters.
The findings challenge prior research pointing to a link between exposure to antidepressants in the womb and a greater risk of autism. Instead, severe maternal depression may be the risk factor boosting a child's odds for autism -- not any antidepressant a woman took during her pregnancy, the new study's authors said.
"We know that untreated depression can pose serious health risks to both a mother and child, so it's important that women being treated with antidepressants who become pregnant, or who are thinking about becoming pregnant, know that these medications will not increase their child's risk of autism," study senior author Dr. Roy Perlis, of the department of psychiatry at Massachusetts General Hospital in Boston, said in a hospital news release.
In the new study, Perlis and colleagues analyzed data from thousands of children with either an autism spectrum disorder or ADHD and thousands more children without either disorder. In total, they looked at the antidepressant use of mothers of 1,400 children diagnosed with an autism spectrum disorder and 4,000 kids without the condition. The team did the same for 2,250 youngsters with ADHD and 5,600 without.
Initial results suggested that taking antidepressants during pregnancy did increase the risk of both autism and ADHD in children. However, after the researchers adjusted the data for the severity of the mothers' depression, the link between antidepressants and autism became insignificant.
However, even after adjusting for depression severity among mothers, the link between antidepressants and ADHD risk was still there, the study authors said. But because the study simply looked at past data, it could only point to an association, it could not prove cause and effect.
