So, I think the first thing to realise is, I guess, that—and I'm a medical doctor by training—of course diagnosis is helpful for some purposes, because we need a kind of 'yes/no' decision for a lot of things that we have to make decisions about, like treatments—yes/no. But, actually, all the research has shown that, with neurodevelopmental conditions, there isn't a firm cut-off—they lie on a continuum. So, it isn't quite like an infection—you've either got it or not. And research has shown very clearly that—. And we've got other things in medicine as well: we've got blood pressure, and we call it high blood pressure and we decide to do something.
So, in terms of the diagnostic assessment, do we have it right? This is quite a laden question. I mean, I think the primary thing is that we want to help children, young people and adults who've got these difficulties. And, of course, a diagnosis is helpful where you've got to have a specific treatment, and a diagnosis is helpful if you need specific resources and support in work, but it isn't the best way for allocating resources around education. They weren't designed for that. The sort of medical criteria, if you like, don't necessarily say, 'Well, how much is this child struggling in the classroom? How much is this family struggling?' So, whilst diagnosis can be helpful, it is not the be-all and end-all. So, we need to think it doesn't mean either/or—we don't get rid of diagnosis, but we do have to acknowledge that there is a spectrum. And quite often I'll see families who don't quite meet diagnostic criteria. I'll draw out a graph and say, 'Look, your child has still got problems, but I'm not going to use medication', for example, for ADHD.
The second issue about assessment, I think, of course, because demand is high, and the assessments are really thorough, one of my concerns is that we spend a lot of money and time on the assessment to get this correct diagnosis, but the diagnosis, in a way, is not quite as hard-cut as, say, an infectious disease, and of course it's very time-consuming and it's really quite late by that stage. So, I feel that our diagnostics [Correction: 'support'], before the diagnostic process starts, need[s] to start early in schools and other places before they get to somebody like me who's very expensive, and it takes a long time to get to someone like me. I think the assessment process is long once they get to us, but I think the help should start before they come to someone like me, because people could wait for two or three years and not get any help. In the meantime, they've developed mental health problems and then they may have weeks and weeks of assessment and so, to me, that isn't logical from a research perspective, and it is of course extremely distressing for families and young people who, in the meantime, may be excluded from school.
So, I kind of feel that—. Sorry, I'm not sure I've answered your question, but everything should start before they get to assessment. And I think the emphasis should be much more on intervention and support rather than just the diagnosis. It's not saying we dispense with diagnosis, but, at the moment, everything rests on the diagnosis—you need the diagnosis to get everything else, and you're waiting for years before you do.
