About this site

Check ADHD Now is an educational website about ADHD. It explains what ADHD is, how it shows up at different ages, what an assessment involves, what treatments exist, and how people manage it day to day.

That is all it does. It does not diagnose, it does not score anything, and it does not know anything about you.

What this site is not

• Not a test. There is deliberately no questionnaire that produces a result. Online tests cannot separate ADHD from the many other things that cause the same difficulties, and that separation is most of what a real assessment is for.
• Not medical advice. Nothing here is tailored to any individual, because it cannot be. Your own doctor is the only person who can tell you what applies to you.
• Not a substitute for assessment. Recognising yourself in a description is not evidence of a condition. It is, at most, a reason to have a conversation with a professional.
• Not country-specific. Who can diagnose ADHD, how you get referred, what treatment is available and what it costs vary enormously between countries and regions. This site stays general on purpose rather than risk describing the wrong health system to you — and points you at official sources for your own country instead.

How the content is written

The aim throughout is to describe what is generally accepted, and to be explicit where things are uncertain or contested rather than smoothing over it.

A few principles the pages try to follow:

• Every symptom comes with what else causes it. This is the most important editorial rule on the site. Poor sleep, anxiety, depression, thyroid problems and chronic stress produce difficulties that look identical to ADHD, and a page that lists symptoms without saying so is misleading by omission.
• Uncertainty is stated, not hidden. Where evidence is thin — hormonal effects, late-onset ADHD, most supplements — the pages say so.
• No dosing information. The medications page explains how the drug classes work and what to expect, and deliberately contains no doses and no recommendations about what anyone should take.
• Neither dismissive nor romantic. ADHD is not an excuse and it is not a superpower. Both framings get in the way of people being taken seriously.
• Plain language. Clinical shorthand like "often loses items necessary for tasks" is translated into what it actually means.

How it is organised

Every page is an article meant to be read. There is nothing to fill in and nothing to submit.

The symptom guide is the one reference page — it takes each common symptom in turn and explains what it means, what it looks like in practice, and what else causes the same thing. It is a glossary, not a checklist: there is nothing to tick and no score at the end.

Two things on the site do move. The meditation and breathing page has a breathing pacer you can follow and an illustrated walk-through of a basic practice. Neither collects anything or produces a result — they are teaching aids, not assessments, and the page works without them if you have JavaScript turned off.

Official ADHD resources by country is a directory of government health services, national clinical guidelines and established charities for several countries. It is the one place the site gets country-specific, because that is where country-specific answers belong.

Privacy

There are no accounts, no sign-ups, no email capture, and no advertising. Nothing here builds a profile of you, and nothing is sold or shared with anyone.

Nothing is stored between visits except your choice of light or dark theme and typeface, which is kept locally in your own browser and never leaves it.

Accessibility

Every page offers a dark theme and a switch to Atkinson Hyperlegible, a typeface designed for readability. The site works without JavaScript, respects reduced-motion preferences, and is built to work with a keyboard and with screen readers. If something is hard to use, that is worth knowing about.

Limitations worth being honest about

This is a small, independent website, not a medical institution. It is not peer-reviewed, it is not written by a clinician, and it does not carry the authority of a national health service or a specialist organisation.

What that means practically: use it to understand the terrain and to prepare better questions. For anything that affects a decision about your health, go to a qualified professional, your national health service, or an established ADHD organisation in your country. Where those sources disagree with this site, believe them.
