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.
Prior studies using home movies have shown that signs of autism can be detected between 8-12 months. A study looking at head circumference found statistical differences prior to 12 months. And one study looking at movements found differences between 4-6 months.etrospective studies, largely involving review of home movies, have suggested that autism can be diagnosed as early as 6-12 months, suggesting that parental report is not an adequate screen because subtle signs are hard to detect without rigorous observation.
