Lewy body dementias → Lewy body disease – Is the usual name used in both DSM5 and ICD11 and would avoid a lot of confusion that arises from the article's present name Iztwoz (talk) 19:28, 17 November 2020 (UTC)
 * I do not think so. In ICD-11, Lewy body disease does not seem to be the same as Lewy body dementia, because Parkinson’s disease is not included there.  And Lewy Body Dementia *is* the most commonly used term.  And the division between neurologists who specialize in dementia and those who specialize in movement disorders is why there is a division. Although confusing, it is a result of professional disagreements and is likely to stay with us. The terminology is what it is, and this is the most correct according to sources.

 * It's usual to include all well-known aka's ? Lewy body disease is in the title of one of the citations - why include disorders and exclude disease ? Lewy body disease is well explained in DSM5. When you say that Lewy body dementia is the most commonly used term seems probable that this term is being used to refer to Dementia with Lewy bodies ? DSM5 explains the difference in the term used by neurologists as being used for PDD, in which the basal ganglia are affected (movement) and for the major dementia Dementia with Lewy bodies where the cortex is primarily affected. As confusion in the terms is evident why not have the proposed name change ?--Iztwoz (talk) 21:11, 17 November 2020 (UTC)
 * Sorry, I was out yesterday at med app'ts and keeping up with what I could via iPad hotspot typing. I think the Japanese prefer the "disease" term, so you will find that used in their sources and reviews, but how different groups use the different terms only introduces more confusion, particularly if you view how ICD-11 is organized.  See Wikipedia_talk:WikiProject_Medicine/Archive_144.  I think if we change the name to disease we will introduce an equal amount of confusion in a different direction without solving the underlying issue, which is inherent because of the push-pull that exists between DLB specialists and Parkinson's people, who don't want to let go of their "brand". There are efforts underway to solve the nomenclature problems, but the movement disorder people are at odds with the neurocognitive dementia people, and the terminology issue looks to be unlikely to be resolved any time soon.  I like what you've done with making it plural, as that may help.  Sandy Georgia  (Talk)  16:37, 18 November 2020 (UTC)
 * Thanks - I'm happy with the plurals use so will withdraw the proposal.--Iztwoz (talk) 19:45, 18 November 2020 (UTC)

I would like to withdraw the proposal as new name change is acceptable.--Iztwoz (talk) 19:45, 18 November 2020 (UTC)


 * The “new name” is causing all kinds of problems. First, no such thing  Not in use anywhere by any source of credence in the way Wikipedia has done.  Second, WP:SINGULAR: LBD is one thing— a term describing several conditions.  Third, made without consultation, unilaterally, in the midst of a short discussion.

 * The page name was changed to try to avoid confusion (which was very evident) with Dementia with Lewy bodies (as was pointed out at the time) - Lewy body dementia on it's own is very often taken to be a synonym of Dementia with Lewy bodies - to give an example of just one -. So that a search for Dementia with Lewy bodies but entering up the oft-used synonym will go to the completely wrong page. Several references used in the lead use the plural dementias. Perhaps a better title would be the aka used Lewy body disorder.--Iztwoz (talk) 19:23, 29 March 2021 (UTC)
 * We exchanged one confusion for another. The problems with calling it Lewy body disorder were explained above.  This is a real-world dilemma, caused by poor naming of the conditions, driven by the Parkinson’s agenda, and we can’t avoid that this issue exists on Wikipedia because it exists in the real world. We need to return the article to its correct place.  Sandy Georgia  (Talk)  19:32, 29 March 2021 (UTC)
 * am not aware of any confusion arising from the page name as is ? think it does avoid confusion with DLB.--Iztwoz (talk) 19:40, 29 March 2021 (UTC)

Misnamed article
Three years on, this article is still misnamed, based on apparent misunderstandings above. Article names are WP:SINGULAR on Wikipedia. And the WP:COMMONNAME is Lewy body dementia. That the established vocabulary is confusing (Lewy body dementia vs. Dementia with Lewy bodies) is beyond Wikipedia: see the vocabulary section of this review article. The move from singular to plural breaches Wikipedia naming conventions on both singular and common name. Samples: Sandy Georgia (Talk)  06:22, 7 December 2023 (UTC)

 * I just moved it for this exact reason. I don't see why we would keep it on the plural form – neither is it a plurale tantum nor is it mainly or nearly only known in its plural form. –Tobias (talk) 19:11, 19 April 2024 (UTC)
