Brain study reveals hidden link between autism and ADHD

A new brain study reveals that the severity of autism-like traits, not just formal diagnoses, fundamentally shapes neural wiring in children, including those with ADHD, pointing to a distinct developmental pathway. | Contesto: cronaca

• Brain study reveals hidden link between autism and ADHD

Contesto

Scientists are uncovering a surprising connection between autism and ADHD that goes deeper than clinical labels. The research suggests it is the intensity of autism-like characteristics, rather than a diagnosis alone, that influences brain organization. This holds true even for children who do not have an official autism spectrum disorder diagnosis. The study specifically identified that certain brain networks associated with cognitive function and social behavior remain atypically connected. This altered connectivity is most pronounced in children who exhibit stronger autism-related symptoms. The persistence of these neural patterns hints at a divergent developmental trajectory. These findings challenge a purely categorical view of neurodevelopmental conditions, emphasizing a continuous spectrum of traits. The work underscores how underlying brain wiring correlates more closely with behavioral severity than with diagnostic boundaries. By focusing on the brain's functional architecture, the research provides a clearer biological basis for overlapping symptoms. It opens new avenues for understanding the shared and distinct mechanisms in autism and ADHD.
