Daniel Geschwind, MD: What is autism? An expert explains

"Some individuals with autism have challenges processing senses. Others struggle to communicate. Still others might have a tough time socializing, thinking, physically moving or just going about daily living.

People with autism have their own ways of interacting with the world, because autism is a developmental disability that affects everyone who has it a little differently, according to Dr. Daniel Geschwind, the Gordon and Virginia Macdonald distinguished professor of human genetics, neurology and psychiatry at UCLA.

Geschwind has spent 25 years studying autism and what causes it. To mark Autism Awareness Month, CNN talked with him about what autism is and what causes it.

CNN: What is autism?

Dr. Daniel Geschwind: Autism refers to a broad range of conditions characterized by challenges with social skills and social and communication and repetitive behaviors, resistance to changes in routine, or restricted interests. I prefer to call it “the Autisms,” because it’s not one thing, and no two autistic children or adults are exactly alike even though they may share basic features. People with autism may also have some sensory-motor integration issues, especially sensory hypersensitivity."
