The prefrontal cortex regulates 'Temporal Discounting'—how the brain values a reward (or consequence) based on how far away it is in time. In a neurotypical brain, a deadline three months away exerts a mild, steady pressure that motivates daily action.
In the ADHD brain, the temporal discount curve drops off a cliff. If an event is not happening "Now" or within the next 48 hours, it mathematically does not exist to the reward circuitry. The brain refuses to deploy dopamine (motivation) for an event it perceives as an abstract fiction (June 1st).
Additionally, 'Task Chunking' requires immense executive function. To break down "Q3 Analysis," the brain must hold the massive end-goal in working memory while simultaneously running a simulation to deduct the sequential steps backward. The weak ADHD working memory buffer crashes under this load. The brain physically cannot visualize the path from A to Z, resulting in total task avoidance.
