The ASD Video Glossary is a web-based tool built to help families and professionals learn more about the early signs of autism. This tool was developed by the Florida State University Autism Institute in collaboration with First Signs and Autism Speaks and has been available to the public free of charge since 2007. The Glossary contains more than 100 video clips illustrating the diagnostic features of ASD. Side-by-side video clips show behaviors that are typical in contrast with those that are red flags for autism. The Glossary also contains over 100 video clips to illustrate common treatments available for children with autism. The ASD Video Glossary has been brought into the Autism Navigator collection and updated to be in line with the new DSM-5 diagnostic framework.
