Really interesting question, Alex. So I started researching hypermobility when I first came to Brighton Sussex medical school in 2009 when. And 10 years ago it was 2015 when I was in the middle of almost end of my PhD. So at that time in, when I was kind of thinking up ideas for my PhD and working with Hugo Critchley in that area, what we mainly knew about hypermobility was we knew about some of the physical health problems and we knew a little bit about possible links with neurodivergence. Of course, we weren't calling it neurodivergence then. There was one or two case studies, well, maybe a few more of children with what was then called Asperger syndrome, having Marfan syndrome or having lax joints. There was also a small literature, I think, two studies about ADHD in children and them being more likely to be hypermobile. But it wasn't really until, you know, the late 2010s and the early 2020s that we really solidified our knowledge on ADHD, autism and hypermobility. And also the work that we did then further linking that to some of these physical, physical issues. So when I started, the interest was all in anxiety and we actually had another anxiety paper published a couple of weeks ago and a few observant people on social media did say to me, but don't you think that these people might have been autistic or adhd? Don't you know hypermobility is associated with autism and adhd? And I had to write back and say, of course, you're absolutely right. But when I designed that study, we didn't really. And although we were interested in it, we didn't, we didn't necessarily control for it or look for it. But what we did find in this study that we did then that we just had published this functional imaging study, we found that there was overactivity in a part of the brain that is to do with fear processing and emotion processing, the amygdala. This is a hypermobility and anxiety study. But we also found that the part of the brain that is responsible for regulating yourself, the frontal cortex, was underactive and there was also some interesting differences in insula. And what's fascinating is, although it's an entirely different study, different pictures that they're looking at in the brain scanner, this is classic what ADHD brain imaging looks like. So when they were doing the ADHD brain imaging that, you know, showed that, were they really taking into account the role of hypermobility and anxiety? When we were doing this imaging, were we really taking into account things like adhd? They might all be actually sort of the same or very similar. And this reminds me of something. So when I first started, there was quite a bit of interest in hypermobility and anxiety. There's a group in Spain that had been working pretty hard in that area and they published a lot about hypermobility and anxiety. And I remember finding about 10 years ago, I can't remember the exact year it was published, but I think it was about 2013, 2014. A brilliant paper. Some people would think it was comical, but about how hypermobility was associated with increased chocolate consumption, increased tobacco consumption and increased alcohol consumption. And the. I can't remember whether it was the chocolate consumption or the tobacco consumption. I think it was the chocolate consumption correlated with a fear sensitivity index. So these authors, quite rightly at the time said to themselves, are these. And I think this was more common in women, are these hypermobile, anxious people regulating their anxiety with chocolate, tobacco, alcohol? And that seemed plausible, and I'm sure it is plausible. But now as a neurodevelopmental clinician, and obviously there's so many differences in terms of how we think about and understand ADHD and autism compared to 10 years ago. I mean, that's. Well, nearly 10 years ago. We didn't even. You couldn't be diagnosed with both. The DSM wouldn't allow. Was only until DSM 5 in 2014 that that. But now I think to myself, that study, that amusing study, because I sometimes include it in slides is, you know, were these people actually regulating. Were they trying to maintain attention? Were they regulating adhd? Because so many people with ADHD use stimulants of all sorts, you know, prescribed and unprescribed, often smoke. And we think of people sometimes regulating with sugar, you know, especially once ADHD medicine is worn off, you know, kind of midnight Haribo or what have you. And so it seems that that actually could be telling the same story in different ways.
