High-functioning autism, often associated with Autism Spectrum Disorder (ASD) Level 1, can be challenging to diagnose because symptoms may be subtle.
People with high-functioning autism may have average or above-average intelligence and strong language skills, but they often struggle with social interaction, flexibility, and sensory sensitivity.
The Diagnostic Process
Diagnosis typically begins with a developmental screening by a pediatrician or psychologist. If signs of autism are present, a more in-depth evaluation is conducted. This often includes:
Observation: A specialist watches how the individual communicates, plays, and interacts.
Interviews: Parents or caregivers may be asked about developmental history and behavior patterns.
Standardized Tools: Professionals may use tools like the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R).
Additional Assessments: Cognitive and language tests help rule out other conditions and provide a full picture of the individual's strengths and challenges.
Diagnosis may occur in childhood or later in life, especially if symptoms were previously overlooked. Early diagnosis can lead to earlier support and better long-term outcomes.
