Why is High-Functioning Autism No Longer Used?
The Shift in Terminology
The term “high-functioning autism” was once used to describe autistic individuals with average or above-average intelligence who required less daily support. However, it is no longer part of official diagnostic language. In 2013, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) replaced separate autism-related diagnoses with the broader category of Autism Spectrum Disorder (ASD), classified into three levels of support needs.
Why the Change Happened
The term “high-functioning” can be misleading. It focuses on perceived abilities—like verbal skills or academic performance—while overlooking challenges in areas such as sensory processing, executive functioning, or social interaction. The DSM-5 framework instead evaluates individuals based on the type and level of support they require, creating a more accurate and inclusive picture.
The Impact of Updated Language
Using “Autism Spectrum Disorder” with support levels helps reduce stigma and ensures that all autistic individuals—regardless of IQ—can receive the appropriate resources. This change promotes a better understanding of autism as a spectrum, where strengths and challenges vary widely from person to person.
Conclusion
Understanding why the term “high-functioning autism” is no longer used helps create a more accurate, respectful, and inclusive picture of autism as a spectrum. Language matters, and shifting to the current diagnostic framework allows for better recognition of each person’s unique strengths, needs, and challenges—without relying on misleading labels. The change reflects progress toward a deeper, more nuanced understanding of autism.
