The ADHD brain is uniquely vulnerable to 'Delay Discounting'—the inability to correctly value a future consequence versus a present friction. When you look at the $25 ticket, your prefrontal cortex calculates that the 5 minutes of agonizing cognitive labor required to pay it *now* is worse than a vague, theoretical $150 penalty three months in the future.
Simultaneously, impulse spending is a form of 'Dopamine Foraging.' When the brain is under-stimulated, the basal ganglia (reward center) demands a chemical hit. Adding an item to an online cart and hitting 'Buy Now' triggers a massive, instantaneous release of anticipatory dopamine. You aren't buying the physical product; you are chemically medicating your nervous system's boredom.
Because the ADHD brain relies heavily on visual cues ('Object Permanence'), digital money and automatic renewals are invisible threats. If the bank account isn't physically sitting in front of you as a pile of cash, the brain acts as though the budget is infinite.
