Early adolescence is a period of heightened risk for the emergence of externalising psychopathology, making it an important window for identifying neurodevelopmental risk markers. Differences between predicted brain age and chronological age - termed the brain age gap - reflect variation from age-typical patterns of brain structure. While brain age gap has been closely linked with internalising behaviours in adolescence, less is known about its relationship with externalising symptoms. This study examined whether brain age gap in late childhood/early adolescence (9-11 years) is associated with current externalising symptoms and whether it predicts externalising trajectories over ","pubDate":"2026-10-27","url":"https://www.biorxiv.org/content/10.64898/2026.10.22.761283v1?rss=1"},"indexado":"2026-10-27T21:02:27.205Z"}}
