Executive function is the brain's project-management layer: prioritise, initiate, switch tasks, hold information in mind, and finish. In adult ADHD, the gap is often not knowledge—you know what you should do—but consistent execution.
What patients describe
- "I can't start until it's urgent"
- Paperwork and admin pile up despite real consequences
- Promising to reply and forgetting for days
- Cleaning one drawer instead of the report due tomorrow
Treatment is more than willpower
Strategies (body doubling, external deadlines, simplifying environments) help. So can clinically appropriate medication when evaluation supports it. The goal is a plan you can actually run—not another lecture about discipline.
