Autism is diagnosed through a combination of behavioral assessments, medical evaluations, and developmental screenings. Pediatricians or specialists observe a child’s communication, social interactions, and behavior patterns. Diagnostic tools such as the Autism Diagnostic Observation Schedule (ADOS) and Autism Diagnostic Interview-Revised (ADI-R) are commonly used to assess autism-specific behaviors. Parents and caregivers may be asked about the child’s developmental history and behavior. While there are no medical tests for autism, doctors may conduct genetic testing or neurological evaluations to rule out other conditions. Early diagnosis, often by age 2, allows for timely intervention and support to improve developmental outcomes.
