Researchers Find No Strong Link between Prenatal Ultrasounds and Autism

Scientific American ----------- Suspicions of a link between prenatal ultrasound scans and autism spectrum disorder are nothing new. The technology has exploded in recent decades, giving expectant parents more detailed images of their developing offspring than ever before. And as ultrasound use has sharply increased, so too have diagnoses of autism—prompting questions about a potential relationship. A rigorous new study examining the association between ultrasounds during the first or second trimester of pregnancy and later development of autism spectrum disorder, however, delivers some good news. The study, which analyzed the medical records and ultrasound details of more than 400 kids who were born at Boston Medical Center, found there was no increase in the number of prenatal scans or duration of ultrasound exposure in children with autism compared with kids with typical development or separate developmental delays. In fact, the group with autism had less average exposure time during its first and second trimesters of development than individuals without autism did. The finding adds weight to earlier studies that suggested such scans—which use high-frequency sound waves to create an image of the fetus, placenta and surrounding maternal organs—are not a powerful enough environmental risk to cause autism on their own.
