With neurodivergence, the risk profile for physical illness is meaningfully different from the general population.
🔹 There is more than double the prevalence of connective tissue differences, particularly joint hypermobility.
🔹 Rates of chronic pain, chronic fatigue, dizziness, and autonomic dysfunction (dysautonomia) are significantly higher.
🔹 In people with Ehlers Danlos syndromes, the likelihood of being autistic is approximately seven times higher, and the likelihood of having ADHD is around five higher than population norms.
These overlaps reflect shared biological pathways involving connective tissue integrity, autonomic regulation, sensory processing, and neuroimmune signalling.
The core problem arises when these presentations are treated as separate and unrelated conditions.
In practice, this fragmentation leads to:
🔹 Missed diagnoses of hypermobility, dysautonomia, or connective tissue disorders
🔹 Under recognition of physical drivers of pain, fatigue, and cognitive load
🔹 Misattribution of physiological symptoms to anxiety, behaviour, or emotional dysregulation alone
Children and adolescents are particularly vulnerable.
It is not uncommon for pain related avoidance to be labelled as school refusal, autonomic symptoms to be framed as anxiety, fatigue and sensory overload to be interpreted as poor motivation or emotional instability.
In these situations, the focus shifts toward managing the behaviour rather than investigating why the body is struggling.
The result is that the visible response becomes the problem, while the underlying physical reality remains unrecognised and untreated.
An integrated assessment is needed, where neurodevelopment, connective tissue health, autonomic function, pain, and fatigue are viewed as part of the same clinical picture rather than competing explanations.
