Early identifications and diagnosis of autism

Identification and diagnosis of autism spectrum disorders

Research projects

Woman and a baby playing with a pile of blocks.Identifying the early behavioural signs of Autism Spectrum Disorders (ASDs) in infancy and toddlerhood are critical to understand how ASDs develop and manifest in the first years of life. This knowledge also assists in identifying and diagnosing children earlier, enabling them to receive intervention in their early and most important years.

Results from many studies both at OTARC and by other researchers clearly shows that early signs of ASD can be reliably detected in infants and toddlers later diagnosed with an ASD. On the basis of these findings we undertook the Social Attention and Communication Study (SACS) which showed that ASDs could be identified during children's second year of life through routine developmental surveillance within the Victorian Maternal and Child Health Service. The SACS is now being evaluated throughout Australia as well as in other cultures, with trials underway in Poland, Korea, Japan and China. We are also following up the children who participated in the SACS to study their cognitive, communication and social development as they grow older.
