Yes, studies of ADHD motivational circuits on fMRI show that key reward‑centred brain regions are different in people with ADHD. In particular, altered striatum activity in the rewards pathway suggests that the way the brain responds to motivation and incentives is not quite the same, helping explain some of the motivational difficulties seen in ADHD.

Functional brain imaging reveals that the ventral striatum often has reduced activation during tasks involving reward anticipation in ADHD. This blunted response means that rewards with delayed payoff may feel less motivating, and immediate rewards become more compelling. Such findings offer deeper insight into how motivation works (or doesn’t) in ADHD, giving clues for treatments focused around reward sensitivity and motivation.

How Altered Motivational Circuits Relate to ADHD Symptoms

Below are common symptoms tied to these fMRI findings and how treatments can help:

Reduced Pursuit of Long‑Term Goals

Tasks with delayed outcomes, like saving towards something, sticking with study plans, or maintaining routines, may feel especially unrewarding for people with ADHD. Medication (especially stimulants) can help by boosting dopamine release and enhancing sensitivity in the rewards pathway, while CBT can offer strategies to set up smaller rewards, maintain motivation, and build structure.

Impulsivity and Preference for Immediate Rewards

Because altered striatum activity can make short‑term rewards seem relatively more appealing, impulsive decisions are more common. Behavioural therapy and motivational coaching can help increase awareness of long‑term consequences, while medication can support more balanced dopamine regulation.
