Is ADHD real? That’s not the question that matters most.

You may have seen the debate sparked by Channel 4’s documentary The Great ADHD Myth?, which asked whether ADHD is a genuine neurodevelopmental condition or something explained by modern life, screens, diet, stress. It’s prompted a lot of discussion, from clinicians, charities and people with ADHD themselves.

We’re not here to go over the science again. Others have already covered that in detail. What we want to talk about is something that’s been harder to find in the coverage: what actually happens to someone while that debate plays out.

What does the evidence actually say?

ADHD isn’t new, and it isn’t seriously in question among the people who study it. It’s been recognised and researched for decades – long before smartphones, social media or ultra-processed food existed – and it remains widely accepted by clinicians and health bodies worldwide as a neurodevelopmental condition.

That doesn’t mean lifestyle doesn’t matter. Sleep, exercise, stress and screen time all affect how anyone functions, whether they have ADHD or not. But that’s different from saying they cause ADHD in the first place. 

For a lot of people, that’s not a debate. It’s a familiar fight to be believed and taken seriously, now questioned on primetime television. 

Something big gets lost in that debate. Even the documentary’s own presenter admitted it: “There’s no doubt that the people seeking these diagnoses are genuinely struggling; that isn’t in question.”

So what’s the real issue?

The scale of unmet need. According to the House of Commons Library, more than 735,000 people in England were waiting for an ADHD assessment as of December 2025. Over six in ten adults on that list had already been waiting more than a year.

Those people are navigating their symptoms every day. Amid all the controversy, that’s easy to forget. 

What if you’re still waiting for an assessment?

Whatever the eventual answer turns out to be about causes, how ADHD should be diagnosed, or the best ADHD treatment – none of that changes what you’re living with right now. Feeling better doesn’t have to wait for the debate to be resolved. 

In the meantime, you can still work towards understanding what’s actually going on for you, and learn strategies to manage day-to-day life.

Importantly, you still deserve to be taken seriously by the people around you. 

Do you need a diagnosis to get support?

No. Support shouldn’t be conditional on where you are in that process. Whether you’re years from the top of a waiting list, unsure if you even want a formal diagnosis, or already diagnosed and working out what helps, it matters just the same.

Where does that leave us?

Among the people who study ADHD closely, there’s little disagreement that it’s real. The more useful conversation is what we’re doing, as services and as a society, for the hundreds of thousands of people currently living with it.
