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.
The new study looked at children aged 6 to 17 with special health care needs and autism spectrum disorder in 2011.
