Autism can be detected at age 1 year in some (but not all) toddlers Results of the Pierce study (2011) indicated that it is possible to detect some toddlers showing early signs autism and other delays at 12 months using a simple, broad band screening tool (i.e., the CSBS DP IT Checklist) that takes only 5 minutes for a caregiver to complete.
Autism Speaks and other autism organizations are working hard to raise awareness of early signs among physicians as well as parents. From birth to at least 36 months of age, every child should be screened for developmental milestones during routine well visits. When such a screeningâor a parentâraises concerns about a child's development, the doctor should refer the child to a specialist in developmental evaluation and early intervention.
