Take a Screener
Both screeners ask you to rate how well each statement describes you, from strongly disagree to strongly agree. Answer for your whole adult life at baseline — not your worst month, not who you'd like to be. Alongside the trait items, both screeners include the context checks a diagnosis actually requires (childhood onset, cross-setting presence, real impairment) and screening items for the patterns that famously imitate ADHD — anxiety, depression, sleep problems, bipolar spectrum, autism, trauma, and OCD. If your answers fit a look-alike pattern, your result will carry a ⚑ flag explaining the possible mix-up.

Exhaustive screener
Full coverage of inattention, hyperactivity-impulsivity, executive function, and emotional regulation, six onset/context/impairment items, and a complete 20-item look-alike screen across seven patterns.
Before you start: this is a self-reflection tool, not a diagnostic instrument, and its flags are hypotheses, not findings. If you're currently inside a depressive episode, an anxiety spike, a stretch of terrible sleep, or fresh grief, your answers will reflect the state more than the trait — the honest move is to retake it when the storm has passed, and to bring the state itself to a professional now.
