Story summary

The study, published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, finds early limbic disruptions in children and adolescents with ADHD.
Analyses of 169 participants show more severe ADHD symptoms correlated with lower limbic connectivity.
The researchers used diffusion MRI scans across three time points to confirm these features are stable.
Findings indicate early limbic white matter differences may influence ADHD symptom severity throughout development, supporting a dimensional view.
