What is autism spectrum disorder?

Autism, also called autism spectrum disorder (ASD), is a complicated condition that includes problems with communication and behavior. It can involve a wide range of symptoms and skills. ASD can be a minor problem or a disability that needs full-time care in a special facility.

People with autism have trouble with communication. They have trouble understanding what other people think and feel. This makes it hard for them to express themselves, either with words or through gestures, facial expressions, and touch.

People with autism might have problems with learning. Their skills might develop unevenly. For example, they could have trouble communicating but be unusually good at art, music, math, or memory. Because of this, they might do especially well on tests of analysis or problem-solving.

More children are diagnosed with ASD now than ever before. But the latest numbers might be higher because of changes in how it’s diagnosed.
