Taking antidepressants during pregnancy is unlikely to raise the risk of having a child with autism.

How researchers design autism prevalence studies has a significant impact on the results, says Eric Fombonne.

About 1 in 100 children in India under age 10 may have autism, and nearly 1 in 8 at least one neurodevelopmental condition.

High blood pressure, preterm birth and other pregnancy complications may increase the risk of autism.

Children born to women who received a routine vaccine while pregnant are not at an increased risk of autism.

Food allergies may be more than twice as common among autistic children as among their typical peers; boys with autism also tend to have skin and respiratory allergies.

Children born to women who had diabetes or high blood pressure while pregnant may be at an increased risk of autism.

A prospective study shows that antipsychotics mess up metabolism, autism is tied to a doubled risk for food allergies, and a report reveals pervasive sexual harassment in science.

More boys than girls have autism; diagnostic biases and genetic factors may explain the skewed sex ratio.

The bulk of the increase in autism prevalence in the United States between 2000 and 2012 can be attributed to children on the mild end of the spectrum.
