how do they test for autism in adults

They test for autism in adults through a comprehensive evaluation process rather than a single test. This evaluation typically includes multiple appointments with a clinician who conducts thorough interviews, behavioral observations, and cognitive activity-based tests. Adults or their loved ones may be asked detailed questions about developmental history and current symptoms. Common diagnostic tools for adults include standardized interviews and observation schedules like the Autism Diagnostic Interview-Revised (ADI-R), Autism Diagnostic Observation Schedule (ADOS), and specialized questionnaires such as the Autism-Spectrum Quotient (AQ). The assessment aims to identify social communication differences, repetitive behaviors, sensory processing differences, and other traits related to autism. The evaluation may be provided by a psychologist or psychiatrist experienced in autism and may also assess co-occurring conditions like ADHD or mood disorders. There are no medical tests like blood tests for autism; instead, diagnosis is based on clinical judgment and standardized tools.
