About Autism
Autism spectrum disorder (ASD) is a developmental condition affecting communication, behavior, and social interaction. The spectrum ranges widely in severity and presentation. Support includes behavioral therapy, speech therapy, social skills training, and medications for specific symptoms.
Clinical trials are advancing new treatments for autism. Currently, 100 studies are recruiting a combined 118,939 participants across the United States. Research is being conducted by 65 organizations including Simons Searchlight, Emory University, Stalicla SA and 62 others.
