EARLI Traced Images

Early Autism Risk Longitudinal Investigation (EARLI) is an autism enriched-risk pregnancy cohort that focuses on the prenatal and early life periods of children who have biological siblings already diagnosed with ASD. Based on a research study completed by the Baby Siblings Research Consortium, the recurrence risk of ASD was 18.7% for families with at least one older sibling with ASD. Children with more than one older sibling with ASD were even more likely to be diagnosed, with a 32.2% risk -- twice that of children with only one older autistic sibling. For this reason, EARLI children are at an increased risk for ASD.
