The earliest identification of atypical development among very young infants at risk for a later diagnosis of an autistic spectrum disorder (ASD) is important to facilitate the earliest possible intervention. Existing literature generally presents that anomalous development is not identifiable until the end of the first year of life. However, this is discordant with clinical anecdotes supporting the premise that, in at least some infants, consistent anomalous behaviors may be identified very early, as early as at ages 3-6 months or even before, that may reliably predict an eventual determination of ASD. Dr. Filipek will first present the course of typical development in the first year of life through video segments to focus on the development of social communication as the hallmark target of atypical development. The existing literature pertaining to findings of anomalous development in the first year of life will be briefly reviewed, with specific attention to study designs focusing on infants who are or are not “at risk” versus infants who eventually are or are not diagnosed with ASD. The newest findings will be presented to document the existence of anomalous development as early as at 3 months of age.
