Prenatal Infections and Autism Risk

Date Published: 
January 6, 2014

A new study finds that pregnant women with infections diagnosed during a hospital admission, especially bacterial infections, were at higher risk of delivering a child who later would be diagnosed with autism spectrum disorder. Multiple infections during pregnancy also were associated with the development of autism. An association, however, does not necessarily mean that infections cause autism. The study was published in the Journal of Autism and Developmental Disorders.
