The history of medicine is often written in the names of those who first observed the unobservable. Medical eponyms—diseases named after specific people—serve as a bridge between clinical science and human biography.
While some names honor brilliant pioneers at prestigious institutions like London’s Guy’s Hospital, others carry the dark weight of 20th-century history. Here are 20 significant diseases named after people, explored in alphabetical order.
In 1855, Thomas Addison, a prominent physician at Guy’s Hospital, first described this chronic endocrine disorder. It occurs when the adrenal glands are damaged—often by an autoimmune response—and fail to produce sufficient cortisol and aldosterone.
German psychiatrist Alois Alzheimer identified this condition in 1901 after treating Auguste Deter, a patient with profound memory loss. Upon her death in 1906, he discovered the characteristic “plaques and tangles” in her brain tissue. Today, it remains the most prevalent cause of dementia globally.
Described by Austrian pediatrician Hans Asperger in 1944 as “autistic psychopathy,” his work remained obscure until 1981. It is now categorized under the broader umbrella of Autism Spectrum Disorder (ASD), characterized by social challenges and repetitive behaviors.
Named for Richard Bright in 1827, this term historically described various forms of kidney disease (nephritis). While modern medicine uses more specific terminology like nephrotic syndrome, Bright’s pioneering research laid the foundation for nephrology.
This rare infectious disease is named after Daniel Alcides Carrión, a Peruvian medical student who tragically gave his life for science. In 1885, he inoculated himself with the disease to prove that “Oroya fever” and “Peruvian warts” were caused by the same bacterium, Bartonella bacilliformis.
In 1932, Burrill Bernard Crohn and his colleagues published a landmark paper on “Regional Ileitis.” Although the work was collaborative, Crohn’s name appeared first alphabetically, forever linking him to this chronic autoimmune inflammatory bowel disease (IBD).
John Langdon Down first characterized this genetic condition in 1866. We now know it is caused by a third copy of chromosome 21. It affects physical growth and cognitive development, and its prevalence increases with maternal age.
Irish physician Robert Graves described this autoimmune cause of hyperthyroidism (overactive thyroid) in 1835. Common symptoms include a goiter (swelling in the neck) and exophthalmos (bulging eyes).
In 1912, Hakaru Hashimoto discovered a condition where the immune system attacks the thyroid gland, leading to hypothyroidism. This was the first condition ever recognized as an autoimmune disease.
Thomas Hodgkin (another Guy’s Hospital alumni) identified this specific type of blood cancer in 1832. It is characterized by the presence of Reed-Sternberg cells, which are large, abnormal white blood cells.
Endocrinologist Harry Klinefelter described this condition in 1942. It occurs in males who are born with an extra X chromosome (XXY), often leading to reduced muscle mass and low testosterone.
Coined by Sir Richard Asher in 1951, this psychiatric disorder is named after Baron von Munchausen, an 18th-century officer known for exaggerating his exploits. Patients with this syndrome feign illness or self-harm to gain medical attention.
Sir James Paget, the “father of British pathology,” has his name attached to three unrelated conditions: a bone remodeling disorder, a rare form of breast cancer, and an extramammary skin cancer.
While “shaking palsy” was known in antiquity, James Parkinson wrote the definitive “Essay on the Shaking Palsy” in 1817. The disease involves the death of dopamine-producing neurons in the brain, affecting movement and balance.
Maurice Raynaud identified this condition where cold or stress causes blood vessels in the extremities (fingers and toes) to overreact and constrict, causing the skin to turn white or blue.
Named after veterinarian Daniel Elmer Salmon, this common foodborne illness is caused by Salmonella bacteria. Ironically, the bacteria was discovered by his subordinate, Theobald Smith, but named in honor of Salmon as the department head.
This fatal genetic disorder is named after British ophthalmologist Warren Tay, who noted the “cherry-red spot” on the retina, and American neurologist Bernard Sachs, who described the cellular damage.
Georges Gilles de la Tourette first detailed this neurological disorder in 1884. It is characterized by involuntary repetitive movements and vocalizations known as tics.
Named for Henry Turner, this chromosomal condition affects females who are missing part or all of one X chromosome. Typical features include short stature and loss of ovarian function.
This form of vasculitis was named after Friedrich Wegener. However, in 2011, after his ties to the Nazi party and proximity to wartime experiments were uncovered, the medical community shifted to the descriptive name Granulomatosis with Polyangiitis (GPA).
Cushing’s Disease: Named for neurosurgeon Harvey Cushing, involving excessive cortisol production from a pituitary tumor.
Charcot’s Foot: Named for Jean-Martin Charcot; a condition where bones in the foot weaken due to nerve damage, common in diabetics.
Reiter’s Syndrome: Now renamed Reactive Arthritis due to Hans Reiter’s involvement in Nazi human experimentation.
