How is High-Functioning Autism Diagnosed?

July 27, 2025

High-functioning autism is typically diagnosed through a comprehensive evaluation by a healthcare professional, such as a psychologist or developmental pediatrician. The process involves a detailed assessment of the individual’s behavior, communication skills, social interactions, and developmental history.

The diagnosis is based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which focuses on two key areas: difficulties in social communication and the presence of restricted, repetitive behaviors or interests. For those with high-functioning autism, intellectual abilities are generally in the average or above-average range, but challenges with social interaction and behavior remain.


The evaluation often includes parent interviews, observation of the child’s behavior, and sometimes standardized tests to assess cognitive and communication skills. This thorough process helps ensure an accurate diagnosis, enabling the development of a personalized treatment plan.
