Baron-Cohen S, Allen J, Gillberg C. Autism is currently detected only at about three years of age. This study aimed to establish if detection of autism was possible at 18 months of age.We screened 41 18-month-old toddlers who were at high genetic risk for developing autism, and 50 randomly selected 18-month-olds, using a new instrument, the CHAT, administered by GPs or health visitors.aron-Cohen S, Allen J, Gillberg C.
