Brief History of EDS and the HSDs

The international Ehlers-Danlos Society (formerly the Ehlers-Danlos National Foundation until 2016) brought together some of the best minds in the field who drafted and produced the first major update to the nosology and diagnostic criteria for all forms of the Ehlers-Danlos syndromes since the Villefranche nosology in 1998.

This included describing a brand new diagnostic category called the Hypermobility Spectrum Disorders. (ICD-10 codes not established yet in 2020.) Together with hEDS, these supplant and obsolete the old diagnoses of JHS, HMS and BJHS prior to 2017. (People with these diagnoses may retain them unless re-evaluated for some reason.)

See the rest of the iceberg!

Think of these as the bulk of the iceberg below the water line, not medically visible to the diagnostic eye – until recently (2017).

These are patients who will have many signs of a systemic connective tissue disorder like EDS (including things like myopia, tendonitis, bursitis, subluxations, dislocations, stretchy skin, abdominal hernias, fallen arches, more), but do not fully meet the criteria for any of the currently 13 formally recognized forms of EDS, or similar HCTDs like Marfan syndrome, Stickler syndrome, Osteogenesis Imperfecta, or Loeys-Dietz syndrome. (2019.)

Like IBS and Fibromyalgia, (which happen to both be highly comorbid in this population and probably results of having a CTD), the HSDs are a diagnosis of exclusion.

And all doctors have seen HSD patients already – we are the frequent flyers in your offices in fact, thanks to so many “issues with our tissues”.

You just usually get us after we’ve aged prematurely and come down with arthritis, falling arches, weak teeth, thin skin, neuromas, detached retinas, etc. As some wise person once quipped (we don’t know exactly whom to credit yet):

“If you can’t connect the issues, think connective tissues.”
