What Are the Emerging Brain Structure and Function Biomarkers for ADHD?

Posted August 19, 2025 Updated August 19, 2025 Author: Harriet Winslow, BSc Reviewed by: Dr. Rebecca Fernandez, MBBS

ADHD brain imaging has made significant strides in revealing emerging biomarkers that provide deeper insights into brain structure and function in individuals with ADHD. These biomarkers are playing a key role in enhancing the understanding of ADHD causes and identifying specific brain abnormalities associated with the disorder. Studies have shown that important regions, such as the prefrontal cortex and basal ganglia, which are responsible for attention, impulse control, and executive function, often exhibit structural differences or reduced activity in individuals with ADHD.

Advanced ADHD brain imaging techniques, including functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), are allowing researchers to observe brain activity more precisely. These studies have uncovered distinct patterns of connectivity and activity within the brain, offering a clearer picture of the neurological differences that contribute to ADHD behaviour.

In ADHD in children, brain scans have revealed abnormalities in regions controlling focus, emotional regulation, and self-control. These findings are helping to identify potential biomarkers for earlier, more accurate diagnosis, as well as providing insight into how ADHD causes affect cognitive and behavioural development.

How It Helps

Emerging biomarkers for ADHD offer several key benefits:

Early Diagnosis

ADHD brain imaging biomarkers can lead to more accurate and earlier diagnoses of ADHD in children.

Personalised Treatment

Identifying biomarkers allows for more tailored treatments, targeting specific brain regions affected by ADHD, leading to better outcomes.

Deeper Understanding of ADHD

These new ADHD brain imaging techniques improve our understanding of ADHD behaviour and the structural and functional brain changes underlying the disorder.
