What is autism?

Autism is a developmental disability that affects the way people experience the world. This may include differences in processing senses, thinking, physically moving, communicating, socializing and going about daily living. 

“We’re born autistic and we’re autistic our whole lives,” Zoe Gross, the director of advocacy at Autistic Self Advocacy Network, told USA TODAY. “It affects everything about the way we interact with and perceive the world.”
