- A new study using the traveling-subject (TS) method strengthens evidence that ADHD brains are structurally unique.
- Previous MRI studies on ADHD showed inconsistent results due to technical noise from different scanners and settings.
- The TS method involves scanning the same non-ADHD individuals across multiple MRI machines to create a uniform baseline.
- After removing scanner bias, children with ADHD showed smaller brain volumes in frontotemporal regions linked to attention and emotional regulation.
- The study had limitations, including a non-representative sample and focus only on brain structure in children.
- The TS method could improve ADHD diagnosis, personalized treatments, and reduce stigma by providing neurobiological evidence.
- The findings highlight the importance of robust harmonization techniques in neuroimaging research for accuracy and reproducibility.
