Are There Imaging Markers of ADHD Remission in Adults? 

Yes, there is some emerging evidence that ADHD remission imaging studies have identified brain and neurophysiological patterns in adults who were diagnosed with ADHD in childhood but whose symptoms have lessened or resolved. These adult outcomes appear to be linked with signs of brain plasticity and structural recovery, although the markers are not yet definitive. 

Research combining EEG, reaction‑time tasks, and functional imaging suggests that adults who remit (i.e. show reduced symptom levels and impairment) often have more “normalised” patterns of attentional and vigilance markers. For example, in follow‑ups of adolescents and young adults with childhood ADHD, preparation‑vigilance measures, reaction time variability (especially the ex‑Gaussian parameters mu and tau), and EEG oscillation features (theta power, phase consistency) are notably better in remitters compared to persisters. These results align with imaging findings (including functional MRI) showing less deviation in networks associated with attention and default mode in remitters.  

Indicators of Remission & What They Look Like 

Below are some of the symptoms or cognitive signs linked to imaging or neurophysiological markers of remission and how this might inform treatment: 

Improved Attention and Reduced Variability in Responses 

In people who remit, reaction times tend to become more stable, attentional lapses decrease, and brain oscillatory measures (like theta phase consistency) improve. Behavioural interventions and tasks that incentivise attention can help reinforce these patterns, potentially supporting more stable brain‑network activity. 

Reduced Default Mode Interference and More Stable Brain Networks 

Functional imaging in remitters often shows stronger modulation of default mode network activity, with better suppression during tasks, and more regular connectivity in attention‑vigilance circuits. Interventions (either behavioural, cognitive training, or mindfulness) may help support this stabilisation of brain networks. 

While these imaging markers are promising, they are not yet reliable tools for diagnosing remission in individual cases. Nonetheless, they offer hope that with age, appropriate support, and interventions, some structural and functional recovery is possible.
