Welcome. This is the start of our adult ADHD assessment guide, written for anyone who has begun to wonder whether ADHD might explain things they have lived with for a long time. We understand that arriving here can feel like a big step, so we have tried to make this calm, clear and honest. You do not need to know anything yet. You only need to be curious.

Why we made this adult ADHD assessment guide

Many adults reach this point after years of sensing that something does not quite add up. Perhaps you have always worked harder than the people around you to stay on top of ordinary things. Perhaps a partner, a friend, or your own child's recent diagnosis has made you pause and look again at your own life.

Whatever brought you here, you deserve clear information rather than guesswork. This guide gathers, in one place, what we would want a member of our own family to know before deciding whether to seek an assessment.

What you will find here

We move at a steady pace, from understanding to action:

We are open about the practical questions too, including the cost of an assessment, because clarity helps you decide.

A few things we believe

A private assessment sits alongside NHS care, never in place of it. If you can access an NHS assessment and are content to wait, that is a perfectly good path, and this guide will help you understand it.

We also believe an assessment is not a test you pass or fail. It is a careful, structured conversation that helps you understand how your own mind works. Whatever the outcome, you should come away knowing more than you did before.

If you are reading this for a child as well as for yourself, there is a companion guide for parents that mirrors this one.

Common questions

Who is this guide for?

Any adult who thinks ADHD might explain difficulties they have lived with for years, and anyone supporting them. If you are looking for a child, the guide for parents covers the same ground for under-18s.

Do I need to know anything about ADHD before I start?

No. We begin from the basics and build up gently, so you can start here with no prior knowledge.

Can this guide tell me whether I have ADHD?

No. It is general information, not a diagnosis. Only a full assessment can tell you that, and this guide explains how to arrange one and what it involves.

Is private assessment instead of the NHS?

No. Private assessment sits alongside NHS care. We set out all the routes honestly so you can choose the one that suits your situation.
