The Overlooked Connection: Hypermobility, Neurodivergence & Chronic Illness

For most of my life, I sat in doctors' offices trying to explain a body that didn't seem to function the way everyone else's did. Every symptom was treated like a separate mystery, and every appointment left me even more confused. From the outside, I looked completely fine. But no one saw how much energy it took just to function normally, to stand, socialize, work, and simply get through the day. When I wasn't around people, I spent most of my time in bed, constantly exhausted. Living in constant discomfort became so normalized that I genuinely believed life was supposed to feel this hard. Slowly, it felt like my body was deteriorating, and eventually I accepted that this was simply going to be my life.

My lab results repeatedly came back negative, and at one point I found myself hoping something would finally show up, because at least then I would understand my body. Every clear test felt less like good news and more like a lack of validation, pushing me deeper into confusion.

Then one day, I decided to join an ADHD community on Reddit, in search of some insight and support. What I discovered there was one of the most fascinating connections I had ever encountered. So many people were discussing their joint hypermobility, chronic illness, and nervous system dysfunction, and things finally began to make sense. What I didn't realize was that the answers I had been searching for had been visible my entire life.

As I began assessing my own body and researching further, I realized how strongly I aligned with hypermobility spectrum disorders (HSD), a pattern where joints move beyond their typical range, often bringing pain, instability, and deep fatigue along with them. Researchers have described a real overlap between neurodivergence and hypermobility, especially among people with autism, ADHD, and Tourette syndrome (Csecs et al., 2022; Eccles et al., 2021), and once I understood that, so much of my own life started to make sense in a new light.

For a lot of us living at this intersection, the day-to-day effects can look like:

None of this shows up neatly on a single test, which is exactly why so many of us spend years being told everything looks normal, even when nothing feels normal at all.

Why Does this Connection Happen?

So why does this connection exist in the first place? One leading theory points to connective tissue, the collagen that makes up our joints, blood vessels, and even parts of the nervous system. In hypermobile bodies, this tissue tends to be more stretchy and less stable.

Researchers believe this same variation may also influence how the brain and nervous system develop and process the world. In other words, the same underlying "wiring" that shapes a more flexible, sensitive nervous system, may also show up as a more flexible, less stable body. It's not that one condition causes the other; rather, they may share common roots, which is exactly why so many people live with more than one of these conditions.

So where has all this information taken me? Truly, it was like a veil finally being lifted and for the first time in my life, I finally had a roadmap and an explanation that made sense.

I began understanding my body and the different signals it was telling me. Instead of working against it, I learned how to work with it. I discovered more appropriate ways to exercise, pace myself, and manage my symptoms rather than forcing myself into advice designed for neurotypical and non-hypermobile bodies.

More than anything, this discovery gave me a sense of empowerment and autonomy. I became more compassionate with myself once I understood that my brain and body were working harder to create stability and equilibrium. Instead of viewing my body as broken, I finally began understanding it. How refreshing!

Unfortunately, advocating for yourself within the healthcare system is no easy feat. That’s where the importance of a multidisciplinary team comes in.

Why Multidisciplinary Care Matters

Unfortunately, countless patients like me continue to move between specialists without anyone stepping back to look at the full picture. What I couldn't understand was how none of the practitioners I had seen had ever connected those dots. No one considered that my wide range of symptoms could stem from a body constantly working harder to stabilize itself, and how that strain could also ripple out to affect the nervous system and brain.

It made me wonder: what does this mean for healthcare systems and working with neurodivergent or chronically ill clients and patients? How can we build more collaborative assessment approaches that recognize these overlaps earlier? How can we create more spaces for practitioners across disciplines to share the patterns they're seeing? The answer is multidisciplinary care teams.

When providers work in isolation, patients are left to become their own care coordinators, repeating their story over and over, hoping someone finally connects the dots. No single specialist is trained to see the whole picture, because each one is trained to look through their own lens. But when a team communicates with each other, patterns become visible that no single appointment could reveal on its own. A physiotherapist might notice something that explains a symptom the cardiologist has been puzzling over. An occupational therapist's notes on fatigue patterns might give a physician the missing piece for a diagnosis.

This is what "full circle" care really means: not just treating each symptom individually, but treating the person; someone whose joints, nervous system, sensory processing, and emotional wellbeing are all deeply connected, not separate problems to be solved one appointment at a time. It's the difference between spending years being told everything "looks fine," and finally getting a plan that reflects how your body and brain actually work together.

As we learn more about the connection between chronic illness and neurodivergence, it's essential to stay open to patients' lived experience. Many people don't fit neatly into narrow diagnostic criteria, and when their concerns are dismissed, opportunities for earlier support and intervention are missed.

As healthcare continues to evolve, collaborative, whole-person approaches and a genuine openness to lived experience can help practitioners recognize these complex overlaps earlier. And perhaps that also means more people can gain a renewed sense of empowerment, autonomy, and self-compassion after years of searching for answers that were, in many ways, right in front of us all along.
