What this research studies

You and your child would be followed over several years to compare children with autism who are raised in bilingual homes to those in monolingual homes, using thinking tests and brain scans during early adolescence. The team will collect information about home language use, run simple tasks that measure attention and planning, and take MRI pictures of the brain at multiple visits to watch how skills and brain networks change over time. The project focuses on executive function—skills like switching attention, planning, and self-control—which change a lot during early adolescence. Results are meant to help families and clinicians make clearer recommendations about using more than one language at home.

Who could benefit from this research

Good fit: Children and adolescents with a diagnosis of autism, especially school-age youth and early adolescents (roughly elementary to mid-teen years), who can complete cognitive testing and MRI visits are ideal candidates.

Not a fit: Adults with autism, very young infants, or individuals who cannot tolerate MRI or repeated in-person visits are unlikely to benefit directly from participating.

Why it matters

Potential benefit: If successful, this work could reassure families that bilingual home environments are safe for children with autism and might support thinking skills, helping guide language recommendations.

How similar studies have performed: Small prior studies suggest bilingualism does not harm language development in neurodevelopmental disorders and some show possible executive function advantages, but long-term brain studies specifically in autistic youth remain limited.
