Start with a focused assessment (history, impairment across settings, rule-outs/comorbids) and brief screeners when helpful. Treatment is skills-first and shame-free: build simple, repeatable systems for planning, time awareness, and task start/finish—think externalize everything (calendars, timers, whiteboards), reduce friction (one-click checklists, staged materials), use “if-then” plans, time-block, and break work into small, timed sprints with real rewards. Layer emotion regulation (DBT skills), motivation strategies (values, “five-minute start,” gamification), and routines for sleep, exercise, and screens. For kids/teens, parent coaching aligns limits, routines, and reinforcement; school coordination can support 504/IEP accommodations. For adults, expect workplace scripts, environment tweaks, and accountability structures (body-doubling, weekly reviews). Medication coordination with psychiatry is available when appropriate, tracked against clear functional targets (on-time arrivals, bills paid, tasks completed). Progress is measured by fewer crises and more consistent follow-through—systems you can run on a busy day, not just a good day.
