The Autism Research Institute was out there first, and that's why they own that coveted URL: http://www.autism.com!
Given that the organization has been around for a very long time, it makes sense that there would be changes to their approach to autism treatment.
Dr. Steven Edelson, who took over leadership of ARI when the renowned Dr. Rimland passed away, provided answer to many questions about the "new" Autism Research Institute. Most importantly, he provides parents with updated information about major changes to the DAN! (Defeat Autism Now!) approach to autism treatment.
