While comparisons between children with ASD and children with language impairment and typical development revealed differences from 8 months of age, the developmental delay group did not differ significantly from ASD on any measure until 24 months of age. At 24 months, children with ASD had lower Communication and Symbolic Behavior Scales Use of Communication scores as compared with all other groups.</p> </sec> <sec id="jpc12614-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The capacity to identify early markers of ASD should facilitate awareness of the risk of an ASD as compared with other developmental problems and point to the need for further developmental assessment, monitoring and provision of early intervention if indicated.</p> </sec> </abstract>
