What Diffusion Tensor Imaging (DTI) Markers Are in ADHD? 

Recent studies have uncovered distinct ADHD DTI markers that shed light on how the brain’s white matter may differ in individuals with the condition. These neuroimaging biomarkers give insight into how connectivity and communication between brain regions are affected, offering a more detailed understanding of ADHD beyond traditional behavioural assessments. 

The most consistent marker identified is fractional anisotropy (FA), which measures the directionality of water diffusion in white matter tracts. In ADHD, FA values are often reduced in key pathways such as the corpus callosum, superior longitudinal fasciculus, and frontostriatal circuits. These reductions suggest white matter integrity loss, affecting processes like attention, planning, and emotional regulation. 

Symptoms Linked to DTI Markers & Treatment Paths 

Below are common symptoms associated with these DTI changes, and how treatment may help address them: 

Impulsivity and Poor Planning 

Disrupted connections in frontal white matter tracts can lead to impulsive behaviour and difficulty organising tasks or keeping routines. Medication (especially stimulants) may help by improving neural signalling and supporting better connectivity, while CBT offers structured strategies for planning, self‑monitoring, and decision making. 

Emotional Dysregulation 

Altered connectivity in tracts linked to limbic regions may contribute to mood swings, irritability, or sensitivity to stress. A combination of behavioural therapy and medication can help stabilise mood and build strategies for managing emotional responses.
