Overview
Autism Diagnosis & Assessment in Houston
Sitting inside the Texas Medical Center at UTHealth Houston, the Dan L. Duncan Children's Neurodevelopmental Clinic handles diagnostic evaluations from infancy through young adulthood — covering autism spectrum disorder, ADHD, learning disabilities, and a range of overlapping developmental concerns. The clinic grew to include providers from the former UT Physicians Pediatric Center for Autism and Related Conditions, deepening its specialty depth. Families get a tailored workup rather than a standard battery, with scheduling staff matching each child to the right clinician.
Best for
Children with complex or co-occurring developmental concerns — autism, ADHD, learning disabilities, or other neurodevelopmental questions — whose families need a thorough, specialist-led evaluation rather than a routine screen.
Their approach
A multidisciplinary team of pediatric neuropsychologists, developmental pediatricians, and advanced practice providers designs each evaluation around the individual child's presentation, drawing on evidence-based assessment frameworks.
What to expect
Schedule directly through the Duncan Clinic at 713-500-8300 (not via central UT Physicians); some clinicians require a referral. After testing is complete, a clinician reviews findings and recommendations with parents in person, and follow-up appointments are available.
