Multimodal MRI and eye-tracking to map brain and social perception differences in autism

Understanding the Mechanisms of Autism : an MRI and Social Cognition Study

Not applicable Interventional Assistance Publique - Hôpitaux de Paris · NCT06334588

This project uses MRI, eye-tracking, and genetic testing to test whether brain structure, function, and gaze patterns reveal distinct profiles in children and young people with autism.

What this trial studies

Researchers will enroll children and young people with autism and healthy controls to undergo multimodal brain imaging (structural and functional MRI), eye-tracking during social perception tasks, clinical scales, and genetic testing. Imaging and behavioral data will be linked to identify anatomo-functional abnormalities and individual brain–behavior patterns. The study includes participants across a wide developmental range and compares those with and without identified genetic anomalies. Results aim to clarify neural bases of social cognition differences in autism and support more precise characterization.

Who should consider this trial

Good fit: Ideal participants are children and young people (ASD: from 3 months to 25 years; healthy controls up to 28 years) who can safely undergo MRI and eye-tracking and have parental or guardian consent.

Not a fit: People with contraindications to MRI (for example pacemaker, intracorporeal metallic body, or severe claustrophobia) or who cannot remain still during scans are unlikely to be able to participate or benefit.

Why it matters

Potential benefit: If successful, the work could help identify individual brain and behavioral patterns that support earlier or more personalized diagnosis and tailored interventions for people with autism.

How similar studies have performed: Previous MRI and eye-tracking studies have repeatedly found group differences in autism, but integrating multimodal imaging with genetic testing to identify individual-level patterns is less common and relatively novel.
