Can Imaging Identify ADHD in Preschool‑Age Children? 

There’s growing interest in whether ADHD imaging preschool‑age studies can spot signs of ADHD early. Early research suggests that some brain features seen on scans do differ in preschool‑age children with ADHD in their brain development, but imaging alone isn’t yet reliable enough for formal diagnosis. It’s promising, but still very much in the research stage. 

Some paediatric MRI work has found patterns like slightly smaller brain volumes in certain regions (frontal, temporal) or differences in white matter development, even in younger kids. These differences in brain development often become clearer with age, meaning that while scans might show hints of ADHD‑related brain structure or connectivity, these features overlap heavily with typical variability in early brain growth. Studies also use functional MRI and resting‑state scans to observe how different brain networks behave, though in preschoolers the data are fewer and noisier than in older children.

  

What This Means for Early Detection & Intervention 

Here are some early‑age signs and how imaging findings might link to practical supports: 

Early Attention Problems & Impulsivity 

Preschool children might bounce between tasks, fail to stay with simple games, or act without waiting. Imaging hints that frontal network maturity and connectivity (white matter or functional) may lag in these children. Early behavioural interventions or preschool‑friendly CBT approaches can help build attention skills; in some cases, medication under specialist supervision may be considered. 

Delayed Cognitive & Emotional Regulation 

Young children may struggle more with frustration, self‑calming, or following simple rules. Brain scans sometimes show slower development in networks linked to executive control and emotional regulation. Structured routines, supportive environments, and therapies focusing on emotional skills can help scaffold development. 

While scans don’t yet substitute for clinical assessment, combining imaging with behavioural observation could improve early detection and tailored care.
