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.
We now know that there is not one autism but many types, caused by different combinations of genetic and environmental influences. The term âspectrumâ reflects the wide variation in challenges and strengths possessed by each person with autism. Autismâs most-obvious signs tend to appear between 2 and 3 years of age. In some cases, it can be diagnosed as early as 18 months. Some developmental delays associated with autism can be identified and addressed even earlier.
