More than 1,1000 mothers, both of neurotypical children and those with autism, filled out a questionnaire that the study team designed. Those mothers who had kids with autism and developmental delays were much more likely to say that they had a fever during their pregnancy. Those who took fever reducers like Tylenol didn't show any increased risk of these problems. And it wasn't having a flu that caused the jump in autism either specifically fever showed a higher chance. One theory is that chemicals called cytokines, which fight infection in the body, get to the fetus via the placenta, and cause harm to the baby's development. But the study team also made it clear that autism is still very much a mystery and that genetics play a really big role. "That's why we're continuing to cast a wide net, and hopefully it will begin to fall into place," lead author Irva Hertz-Picciotto said. Did you have a fever during pregnancy? Or other you the mother of a child with autism? We'd love to hear your take on the new study!
Fever during pregnancy doubles autism risk?
