Understanding ADHD
What is ADHD?
Attention-Deficit/Hyperactivity Disorder is a neurodevelopmental condition affecting approximately 5% of children and 2.5% of adults worldwide (DSM-5-TR, 2022). It is characterized by persistent patterns of inattention, hyperactivity, and impulsivity.
The DSM-5 recognizes three presentations:
- Predominantly inattentive – difficulty sustaining focus, following through, and organizing
- Predominantly hyperactive-impulsive – fidgeting, talking, interrupting, restlessness
- Combined – features of both inattention and hyperactivity-impulsivity
When to seek professional help
Consider seeking a professional evaluation if you experience:
- Persistent difficulties with attention, focus, or organization
- Problems completing tasks or frequently making careless mistakes
- Restlessness, excessive energy, or inability to sit still
- Impulsive behavior that causes problems in relationships or work
Early identification and treatment can significantly improve outcomes.

Jack Squire, Founder
I was diagnosed with ADHD at age 6. I created this tool to help others identify their symptoms and take the first step toward understanding their neurodivergent minds.
Who built this, and exactly how
We would rather be transparent about who is behind this site and exactly how the test works than let you assume more expertise than exists here. This short section covers both plainly and honestly, so you can decide for yourself exactly how much weight to give your result.
This site was built by Jack Squire, the founder. Jack is not a clinician, a psychologist, or a psychiatrist, and no clinician has reviewed this site or its test. We say this plainly because a screening tool that touches mental health should not imply authority it does not have.
The method is straightforward: the test is 18 items mirroring the DSM-5-TR ADHD symptom list, 9 for inattention and 9 for hyperactivity-impulsivity, each answered on a frequency scale. A response of "Often" or "Very Often" counts as a present symptom, and your symptom count in each cluster is compared to a DSM-5-TR-based threshold, 6 for ages 16 and under and 5 for ages 17 and older. It is based on the DSM-5-TR symptom criteria. It is not the ASRS, and it has not undergone independent clinical validation. It does not measure the other requirements for an ADHD diagnosis: symptoms present for at least 6 months, several present before age 12, symptoms across two or more settings, and clear impairment. Only a clinician can evaluate those four things, using a clinical interview and, often, input from people who know you well.
We would rather describe the tool accurately than oversell it. For the full breakdown of what the test measures, exactly how scoring works, and what it cannot tell you, read our our method page. For how we source and correct content, including our policy on sponsorships and affiliate links, see our editorial policy. Both pages exist so that you, or a clinician you eventually talk to, can check our work rather than take our word for it.
