Do Children with ADHD Have Different Brain Imaging Patterns? 

Yes, ADHD brain imaging children studies show that kids with ADHD often display developmental differences in both structure and function compared to neurotypical peers. Neuroimaging and pediatric neuroimaging work reveal that certain volumes, connectivity patterns, and maturation trajectories in brain scans diverge meaningfully in ADHD. 

Large‑scale MRI research, including the ENIGMA consortium, finds that children with ADHD have smaller overall brain volumes and slightly reduced size of specific subcortical regions (like the caudate, putamen, nucleus accumbens, amygdala, hippocampus). Another recent study using a new method to correct for scanner differences showed that frontotemporal grey matter is consistently reduced in children with ADHD. Functional imaging also shows age‑related delays: in ASL‑MRI scans of children aged 8‑12, those with ADHD showed lower blood flow in regions tied to executive function early on, and reduced perfusion in visual processing/spatial cognition areas slightly later. Longitudinal studies (like NICAP) indicate that some brain differences shrink over adolescence, suggesting that ADHD often reflects delayed brain maturation rather than wholly abnormal development.  

Common Symptoms & How Imaging Helps 

Here are symptoms often seen in ADHD children that correlate with imaging findings, and how that can guide treatment: 

Delayed Executive Skills & Poor Attention 

Young children may struggle with planning, following multi‑step instructions, or sustaining attention. Imaging reveals underdevelopment in networks responsible for executive control (e.g. prefrontal cortex), and reduced activation or blood flow in these areas. Behavioural therapies, structured routines, and medication (where appropriate) can help accelerate developmental gains. 

Slower Visual‑Spatial & Sensorimotor Processing 

Tasks involving spatial awareness or visual processing (e.g. puzzles, copying shapes) may be harder for children with ADHD. Imaging findings from ASL‑MRI and similar studies show delayed or lower activation in relevant brain regions. Interventions like targeted training, visual‑spatial exercises, and supportive learning environments can improve processing speed and practical outcomes.
