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.
MRI scans of 6- to 12-month-old infants at high risk of autism were able to predict a diagnosis at 24 months or later. Washington University School of Medicine, St. Louis The MRI scans were taken on 109 high-risk babies who had older siblings with autism and 42 infants with no family history of autism, while they slept at four centers across the country.
