What is the history of Ehlers Danlos?

Ehlers-Danlos syndrome (EDS) is a group of genetic disorders that affect the connective tissues in the body. It was first described by two physicians, Edvard Ehlers and Henri-Alexandre Danlos, in the early 20th century.

Edvard Ehlers, a Danish dermatologist, first identified the condition in 1901 when he observed a patient with excessively stretchy skin and joint hypermobility. He published his findings in a medical journal, describing the condition as "cutis hyperelastica."

Henri-Alexandre Danlos, a French dermatologist, independently recognized a similar condition in 1908. He described a group of patients with fragile skin that easily formed bruises and scars. Danlos also noted joint hypermobility in some of his patients.

Over the years, the medical community began to recognize the similarities between the observations made by Ehlers and Danlos. In the 1960s, the term "Ehlers-Danlos syndrome" was coined to encompass the various subtypes of the condition.

Ehlers-Danlos syndrome is caused by mutations in genes responsible for producing collagen, a key component of connective tissues. Collagen provides strength and elasticity to the skin, joints, blood vessels, and other organs. When the production or structure of collagen is affected, it can lead to the characteristic features of EDS.

Since its initial discovery, several subtypes of EDS have been identified based on their specific clinical features and genetic causes. The most common subtypes include:

• Classical EDS (cEDS): Characterized by hyperextensible skin, joint hypermobility, and increased risk of skin bruising and scarring.


• Hypermobile EDS (hEDS): Primarily characterized by joint hypermobility and related musculoskeletal symptoms.


• Vascular EDS (vEDS): The most severe subtype, associated with fragile blood vessels and an increased risk of organ rupture.

Advancements in genetic testing and research have allowed for a better understanding of the different subtypes and their underlying genetic mutations. This knowledge has improved diagnosis and management strategies for individuals with EDS.

While there is currently no cure for EDS, treatment focuses on managing symptoms and preventing complications. This may involve physical therapy, pain management, bracing or splinting, and surgical interventions when necessary.

Research into Ehlers-Danlos syndrome continues to expand our understanding of the condition and may lead to future advancements in treatment options and potential therapies.
