The ADHD brain exhibits what researchers call 'steep temporal discounting'—the perceived value of a future reward drops to near zero the further away it is. Learning a skill is essentially a long-term investment: suffer now, benefit later. But for an ADHD brain, the 'later' might as well be 'never.' The reward is invisible, so the motivation is nonexistent.
Simultaneously, novelty produces a documented spike in dopamine release. The first exposure to a new domain (guitar, coding, pottery) is neurochemically indistinguishable from the high of a new relationship—intense, consuming, and unsustainable. When the novelty wears off (typically 1-3 weeks), the dopamine crash is equally dramatic.
The anterior cingulate cortex, responsible for persistence and error monitoring, is also underactive in ADHD. This means the brain doesn't generate the 'keep going, you're making progress' signals that sustain neurotypical learners through plateaus. Without these internal progress reports, the ADHD brain concludes that the effort is pointless and redirects energy to the next novel stimulus.
