What’s the Difference Between High-Functioning Autism and Asperger’s?

High-functioning autism (HFA) and Asperger’s syndrome are both part of the autism spectrum, but the key difference lies in the severity of symptoms and the presence of language delays.

Asperger's syndrome, now considered part of the autism spectrum under the DSM-5, is characterized by significant challenges in social interaction and restricted interests, but without a noticeable delay in language development or cognitive skills. Children with Asperger’s often have average or above-average intelligence but may struggle with understanding social cues or engaging in typical peer interactions.

On the other hand, high-functioning autism is a term used to describe individuals who meet the criteria for autism but exhibit relatively mild symptoms and typically have average intelligence. While language skills may develop on time, social communication and behavior challenges are still present.

Both conditions involve challenges with social communication and behavior, but Asperger’s typically highlights no significant delays in speech, while high-functioning autism may include subtle language delays or other signs of developmental differences.
