    👉 Take the free 18-question ADHD self-test (3 min) on the homepage — Start the ADHD Test.

    The fastest way to find out

    If you're asking 'do I have ADHD?', the most useful first step is a validated self-test. Our free 18-question ADHD test is based on the WHO Adult ASRS-v1.1 — the same instrument used by clinicians worldwide for screening adults.

    Take the test now on the homepage. It's anonymous, runs entirely in your browser, and gives instant results across two dimensions: inattention and hyperactivity/impulsivity.

    Common adult ADHD symptoms

    Inattentive symptoms include: trouble finishing tasks, easily distracted, frequently losing things, forgetfulness in daily activities, difficulty organizing.

    Hyperactive/impulsive symptoms include: feeling restless, talking excessively, interrupting others, finishing people's sentences, difficulty waiting your turn.

    What if my test result is positive?

    A positive screen doesn't equal a diagnosis. It means your symptom pattern is consistent with adult ADHD and warrants professional evaluation. Read how to get tested for ADHD next.

    Why self-testing is reliable

    The ASRS-v1.1 has been validated in multiple peer-reviewed studies with sensitivity around 68% and specificity above 99% for the Part A screener. While not diagnostic, it's a strong first signal.
