What Is Autism?
Autism, or autism spectrum disorder, refers to a broad range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication. We now know that there is not one autism but many subtypes, and each person with autism can have unique strengths and challenges. Most are caused by a combination of genetic and environmental influences, and many are accompanied by medical issues such as intestinal issues, seizures and sleep disturbances. An estimated 1 in 59 children in the U.S. is on the autism spectrum.
