What this research studies

This project continues the Autism Phenome Project by bringing participants back for a fifth visit in middle adolescence (ages 14–17) to get MRI brain scans and clinical measures. Children first had scans at ages 2–3.5 and up to three more times between about 4 and 12, and the team will compare those earlier images to the new teen scans. The work includes children with a full range of autism severity and common co-occurring conditions, and uses pediatrician-based Tanner staging to link brain changes with pubertal development. Comparing autistic participants with typically developing peers should reveal different brain development paths that emerge during adolescence.

Who could benefit from this research

Good fit: Best candidates are children with a diagnosis of autism (including those previously in the Autism Phenome Project) now entering or in middle adolescence, along with age-matched typically developing controls.

Not a fit: People without prior early-life data from this cohort or those unable to undergo MRI (for example due to metal implants or severe scanner anxiety) may not be able to participate or gain direct benefit from this follow-up.

Why it matters

Potential benefit: If successful, the findings could help clinicians and families by identifying distinct brain development patterns in adolescence that point to more personalized supports or timing for interventions.

How similar studies have performed: Longitudinal MRI work beginning in early childhood exists but is uncommon, and extending those cohorts into adolescence is relatively novel though earlier APP scans have produced informative results.
