An eponymous disease is a disease, disorder, condition, or syndrome named after a person, usually the physician or other health care professional who first identified the disease; less commonly, a patient who had the disease; rarely, a literary character who exhibited signs of the disease or an actor or subject of an allusion, as characteristics associated with them were suggestive of symptoms observed in the disorder.
Naming systems
Eponyms are a longstanding tradition in Western science and medicine. Being awarded an eponym is regarded as an honor: "Eponymity, not anonymity, is the standard."[1] The scientific and medical communities regard it as bad form to attempt to form eponyms after oneself.[2]
Ideally, to discuss something, it should have a name. When medicine lacked diagnostic tools to investigate and definitively pinpoint the underlying causes of most diseases, assigning an eponym afforded physicians a concise label for a symptom cluster versus cataloguing the multiple systemic features that characterized a patient’s illness.
Most commonly, diseases are named for the person, usually a physician, but occasionally another health care professional, who first described the condition—typically by publishing an article in a respected medical journal. Less frequently, an eponymous disease is named after a patient, examples being Lou Gehrig disease and Hartnup disease. In the instance of Machado–Joseph disease, the eponym is derived from the surnames of two families in which the condition was initially described. Examples of eponyms named for persons who displayed characteristics attributed to a syndrome include: Lazarus syndrome, named for a biblical character; and Miss Havisham syndrome, named for a Dickens character, and Plyushkin syndrome, named for a Gogol character, both fictional persons (the latter two also happen to be alternative names for the same symptom complex). Two eponymous disorders that follow none of the foregoing conventions are: Fregoli delusion, which derives its name from an actor whose character shifts mimicked the delusion it describes; and, Munchausen syndrome which derives from a literary allusion to Baron von Munchausen, whose personal habits were suggestive of the symptom cluster associated with it.
Disease naming conventions which reference place names (such as Bornholm disease, Lyme disease, and Ebola virus disease) are properly termed toponymic, although an NLM/NIH online publication described them as eponymic.[3] Diseases named for animals with which they are associated, usually as a vector, are properly styled as zoonymic; cat scratch fever and monkeypox are examples. Those named for association with a particular occupation or trade, examples of which include nun's knee, tennis elbow, and mad hatter's disease, are properly described as occupational diseases.
In May 2015, the World Health Organization, in collaboration with the World Organization for Animal Health (OIE) and the Food and Agriculture Organization of the United Nations (FAO), released a statement on the Best Practices for the Naming of New Human Infectious Diseases "with the aim to minimize unnecessary negative impact of disease names on trade, travel, tourism or animal welfare, and avoid causing offence to any cultural, social, national, regional, professional or ethnic groups."[4] These guidelines emerged in response to backlash against people and places, based on the vernacular names of infectious diseases such as Middle East respiratory syndrome, and the 2009 swine flu pandemic.[5] These naming conventions are not intended to replace the International Classification of Diseases, but rather, are guidelines for scientists, national authorities, the national and international media and other stakeholders who may be the first to discuss a disease publicly.
Punctuation
In 1975, the Canadian National Institutes of Health held a conference that discussed the naming of diseases and conditions. This was reported in The Lancet where the conclusion was summarized as: "The possessive use of an eponym should be discontinued, since the author neither had nor owned the disorder."[6]Medical journals, dictionaries and style guides remain divided on this issue. European journals tend towards continued use of the possessive, while US journals are largely discontinuing its use.[7] The trend in possessive usage varies between countries, journals, and diseases.[8]
The problem is, in fact, that the possessive case was given its misleading name for historical reasons and that now even educated people, if they are not linguists, often make incorrect assumptions and decisions based on this misleading name. Nevertheless, no native speakers would accept the ungrammatical "men department" as a possible way of saying "men's department" nor claim that this "possessive" and obligatory apostrophe in any way implies that men possess the department.
This case was called the genitive until the 18th century and (like the genitive case in other languages) in fact expresses much more than possession. For example, in the expressions "the school's headmaster", "the men's department", and "tomorrow's weather", the school does not own/possess the headmaster, men do not own/possess the department, and tomorrow does not/will not own the weather. Most disagreements about the use of possessive forms of nouns and of the apostrophe are due to the erroneous opinion that a term should not use an apostrophe if it does not express possession.[9]
The argument is a case of fooling oneself with one's own terminology. After the 18th-century grammarians began to refer to the genitive case as the possessive case, grammarians and other commentators got it into their heads that the only use of the case was to show possession.... Simply changing the name of the genitive does not change or eliminate any of its multiple functions.
This dictionary also cites a study[11] which found that only 40% of the possessive forms were used to indicate actual possession.[12]
Autoeponym
Associating an individual's name with a disease merely based on describing it confers only an eponymic; the individual must have been either affected by the disease or have died from it for the name to be termed auto-eponymic. Thus, an 'auto-eponym' is a medical condition named in honor of: a physician or other health care professional who was affected by or died as a result of the disease which he had described or identified; or, a patient, who was not a health care professional, but suffered from or died as a result of the disease.[13] Auto-eponyms may use either the possessive or non-possessive form, with the preference to use the non-possessive form for a disease named for a physician or health care professional who first described it and the possessive form in cases of a disease named for a patient (commonly, but not always, the first patient) in whom the particular disease was identified.[14] Autoeponyms listed in this entry conform to those conventions with regard to the possessive and non-possessive forms.
Examples of autoeponyms include:
Rickettsiosis: in 1906, Howard Taylor Ricketts discovered that the bacteria that causes Rocky Mountain Spotted Fever is carried by a tick. He injected himself with the pathogen.[15]
Thomsen's disease: an autosomal dominant myotonia of voluntary muscles described by Asmus Julius Thomas Thomsen about himself and his family members.[16]
Carrion disease: Peruvian medical student Daniel Alcides Carrión inoculated himself with Bartonella bacilliformis in 1885 to prove the link to this disease, characterized by "Oroya fever".
Lou Gehrig's disease: although Gehrig, a New York Yankees player of the early twentieth century, was not the first patient described as having amyotrophic lateral sclerosis, the association of such a prominent individual with the then little-known disease resulted in his name becoming eponymous with it.
Eponyms and trends
The current trend is away from the use of eponymous disease names and towards a medical name that describes either the cause or primary signs.[4] Reasons for this include:
A national or ethnic bias attaches to the eponym chosen;
Credit should have gone to a different person;
An eponym may be applied to different diseases, which creates confusion;
Several eponyms refer to one disease (e.g., amyloid degeneration is variously called Abercrombie disease, Abercrombie syndrome, and Virchow syndrome);
An eponym proves invalid (e.g., Laurence–Moon–Bardet–Biedl syndrome, in which findings in the patients of Laurence and Moon were later found to differ from those of Bardet and Biedl).
An eponym honors an individual who has been otherwise discredited. An example is Wegener's Granulomatosis; it was renamed granulomatosis with polyangiitis when Dr. Wegener was found to have had Nazi ties.
Its referent varies by country (e.g., sideropenic dysphagia is Plummer–Vinson syndrome in the US and Australia, Patterson–Kelly syndrome in the UK, and Waldenstrom–Kjellberg syndrome in Scandinavia).
The eponym may be shorter and more memorable than the medical name (the latter requiring abbreviation to its acronym);
The medical name proves to be incorrect;
The syndrome may have more than one cause, yet it remains useful to consider it as a whole.
It continues to respect a person who may otherwise be forgotten.
The usage of the genitive apostrophe in disease eponyms has followed different trends. While it remains common for some diseases, it has dwindled for others.[17]
Alphabetical list
Explanation of listing sequence
As described above, multiple eponyms can exist for the same disease. In these instances, each is listed individually (except as described in item 1 below), followed by an in-line parenthetical entry beginning 'aka' ('also known as') that lists all alternative eponyms. This facilitates the use of the list for a reader who knows a particular disease only by one of its eponyms, without the necessity of cross-linking entries.
It sometimes happens that an alternative eponym, if listed separately, would immediately alphabetically precede or succeed another eponymous entry for the same disease. Three conventions have been applied to these cases:
1. No separate entry appears for the alternative eponym. It is listed only in the parenthetical 'aka' entry (e.g., Aarskog syndrome appears only as a parenthetical entry to Aarskog–Scott syndrome).
2. If eponymous names subsequent to the first are sequenced differently or the eponym is differentiated by another term (e.g., disease versus syndrome), alphabetical sequence dictates which is the linked version versus which is listed as the alternative (e.g., Abderhalden–Kaufmann–Lignac is the linked entry and Abderhalden–Lignac–Kaufmann is the parenthetical alternative entry).
3. If the number of names included in two or more eponyms varies, the linked entry is the one which includes the most individual surnames (e.g., Alpers–Huttenlocher syndrome is the linked entry for the disease also known as Alpers disease or Alpers syndrome).
Some eponyms have an alternative entry that includes the name(s) of additional individuals. An example is Adams-Stokes syndrome; one of its alternative eponyms is Gerbec–Morgagni–Adams–Stokes syndrome. The entry for Adams-Stokes only names the two individuals (Adams and Stokes) whose names are associated with the entry as listed; the later entry for the alternative Gerbec–Morgagni–Adams–Stokes syndrome names all four of the individuals (Gerbec, Morgani, Adams, and Stokes) who are associated with the longer named entry.
Bardet–Biedl syndrome (formerly, aka Laurence–Moon–Bardet–Biedl syndrome, but that construct is now deemed invalid. For fuller explanation, see Laurence–Moon–Bardet–Biedl syndrome) – Georges Bardet, Arthur Biedl
Diogenes syndrome (aka Havisham syndrome, Miss Havisham syndrome, Plyushkin syndrome)– Diogenes of Sinope (the particular usage, Diogenes syndrome, is deemed to be a misnomer)
Wegener's granulomatosis – Friedrich Wegener (This usage is now formally discouraged by professional medical societies due to the Nazi associations of the eponymous physician. The disease is now known as granulomatosis with polyangiitis.)

The only statistical investigation of the genitive case that we are aware of can be found in Fries 1940. Fries found that the possessive genitive was the most common, but that it accounted for only 40 percent of all genitives.
