Getting a Diagnosis: How Is High-Functioning Autism Officially Identified?
August 8, 2025
How is high-functioning autism diagnosed?
High-functioning autism is not a formal medical term, but it's often used to describe individuals on the autism spectrum who have average or above-average intelligence and relatively strong verbal skills. Despite these strengths, they may still struggle with social communication, sensory sensitivities, routines, or emotional regulation.
Diagnosing high-functioning autism typically begins with concerns from parents, teachers, or the individual themselves. A diagnosis is made through a comprehensive evaluation by a qualified professional—such as a developmental pediatrician, psychologist, or neurologist. The process often includes:
- Developmental and medical history review
- Standardized autism screening tools (like ADOS-2 or CARS)
- Cognitive and language assessments
- Observation of behavior and social interaction
Because people with high-functioning autism often "mask" or compensate for their difficulties, especially in structured settings, diagnosis can be delayed or overlooked—especially in girls and adults.
Early diagnosis is essential to access appropriate therapies and supports. Even challenges seem mild, proper identification can make a significant difference in personal growth, relationships, and long-term well-being.
