Classification History

Classification of EDS began in the late 1960’s ~ in 1988 an international nosology of connective tissue that defined 9 subcategories of EDS were proposed. With recent developments and increased medical expertise, a simplified classification of EDS has been revised into 6 major types according to the Villefranche nosology. Based on this refined classification, one in 5000 people is said to be affected by Ehlers-Danlos syndrome. It affects males and females equally of all racial backgrounds.
