Dr Sarah Warley

And I think it's important to say when we talk about the Walsh Institute, so what he's done basically over the past,

35, 40 years, he's amassed one of the biggest databases anywhere in the world.

So he's analysed loads and loads of biochemistry from people not just with ADHD, ADHD, mental health problems, behavioural issues, and he's analysed it to identify what he calls the main offenders, the repeat offenders.

And there seem to be certain biochemical

imbalances that appear again and again in these things.

But his work is based on the database analysis that he's done and also on decades of clinical experience.

But what there isn't are the big RCT trials on his work to further corroborate it.

So again, I keep saying it's about the individual, which is a terrible answer to give, but it's true.

It is about the individual.

Let me explain a little bit about the relationship between the two things.

So copper is a really important cofactor in the enzyme that takes your dopamine, which is the thing you need to focus and concentrate, and it turns it into noradrenaline, okay?

So if you up the free copper level in your body, Walsh's theory is that that

means you're going to have less dopamine and you're going to probably have more, and most importantly, dysregulated noradrenaline levels.

So that's where copper comes into the picture.

Now, zinc is a kind of a mitigating force against that because the more zinc you've got, zinc helps you excrete copper, okay?

So zinc is also important in the production of neurotransmitters.

But if, therefore, you've got too little zinc and you've got too much copper,

Walsh's theory is that's where the dysregulation is coming from.

Not for everyone, but for a big subset of people with ADHD.

Yes.
