This chapter reviews studies on the developmental features, diagnosis, and developmental trajectory associated with autism spectrum disorders (ASD) in the first three years of life. The matter of recognizing early signs of developmental disruption is a critical one, as it opens the door to early intervention. Parents and professionals contribute important insights to the early detection process. Early detection of ASD is usually a process, involving suspicion that something is amiss with the child's development, obtaining validation about concern, and discerning whether the diagnosis of ASD is appropriate. Given that the trajectory of development, such as slowing, plateau, or regression, may be a key factor in determining whether development is truly divergent from the typical path, a single point-in-time assessment for a very young child may not conclusively determine whether a diagnosis of ASD is appropriate.
