Despite increased awareness the majority of children are not diagnosed with Autism until they are nearly four. However much research has shown that catching it early, preferably before 18 months old can make a huge difference. 

To help with recognition of the early signs of  autism spectrum disorders (ASD), autism researcher Dr. Rebecca Landa of Kennedy Krieger Institute ((http://www.kennedykrieger.org) has developed a video tutorial on ASD behavioral signs in one-year-olds. 

The tutorial consists of six video clips comparing toddlers who show no signs of ASD to toddlers who show early signs of ASD. Each video is presented with voice-over explaining how the specific behaviors exhibited by the child, as they occur on screen, are either indicative of ASD or typical child development.
