ScienceDaily (Apr. 26, 2012) — Women who smoke in pregnancy may be more likely to have a child with high-functioning autism, such as Asperger's Disorder, according to preliminary findings from a study by researchers involved in the U.S. autism surveillance program of the Centers for Disease Control and Prevention.

"The study doesn't say for certain that smoking is a risk factor for autism," Kalkbrenner says. "But it does say that if there is an association, it's between smoking and certain types of autism," implicating the disorders on the autism spectrum that are less severe and allow children to function at a higher level. That connection, she adds, needs further study.

Because autism involves a broad spectrum of conditions and the interplay of genetics and environment is so complex, no one study can explain all the causes of autism, she adds. "The goal of this work is to help provide a piece of the puzzle. And in this we were successful."
