Anxiety, Mood, and the Autonomic Nervous System in hEDS/HSD

The Link Between Anxiety and Dysautonomia in Hypermobility

A 2014 case-control study by De Wandele and colleagues compared 80 people with the hypermobility type of EDS to 43 healthy controls. It measured autonomic symptom burden: things like dizziness on standing, heart rate irregularities, temperature regulation problems, and other signs of a nervous system that isn't managing basic body functions smoothly. The hEDS group scored 57.9 (±21.6) on this measure, compared to 11.3 (±19.2) in the control group, a large and consistent difference.

That autonomic symptom burden correlated with affective distress and reduced quality of life in the study. In plain terms: the more dysregulated a person's autonomic symptoms were, the more distress and mood impact they tended to report. That's a correlation, not proof that one directly causes the other, but it's a meaningful pattern that supports treating the two as connected rather than coincidental.

Correcting a Common Anxiety-Hypermobility Statistic

A figure circulates widely in hypermobility spaces claiming that "up to 70% of anxiety patients have hypermobility." That number is a distortion of a real study, and it's worth stating the original finding precisely because the popular version gets both the number and the population wrong.

The actual source is Martin-Santos and colleagues, published in the American Journal of Psychiatry in 1998. That study found joint hypermobility syndrome in 67.7% of patients with panic disorder or agoraphobia specifically (not anxiety in general), compared to 10.1% of psychiatric controls and 12.5% of medical controls, in a sample of 99 patients. That's a striking and specific finding about panic disorder and agoraphobia. It is not evidence that 70% of people with anxiety broadly have hypermobility, and stretching it that far overstates what the study actually showed.

Treating Anxiety as a Physical, Not Just Mental, Symptom

Given this research, a dysautonomia-informed approach to anxiety in hEDS/HSD means treating the autonomic nervous system as one legitimate piece of the picture, worth ruling in or out, rather than assuming anxiety symptoms are entirely situational or entirely physiological. Nervous-system regulation techniques (the kind often used for autonomic symptom management generally) are sometimes discussed alongside anxiety management in this population, though they aren't a substitute for mental health treatment when that's what's needed.

Compression garments, which have real evidence behind them for managing autonomic symptoms like orthostatic intolerance, are sometimes reported to have a calming secondary effect for some people. That is not the same as evidence that compression treats anxiety, and it shouldn't be read as a product recommendation for anxiety specifically. It's a plausible side effect of managing a different, physiologically linked symptom.
