I thought that was the main area impacted. Mainly, reward anticipation cues in the striatum are blunted in those with ADHD and only during reward delivery does it light up, sometimes more so than in those without it. This may play a part in why we (I myself have ADHD) have a strong preference for immediate rewards over delayed ones. There was a study about this I was trying to find. But anyway, are there other areas? Because I was thinking about changing the part in the picture to the striatum instead of the basal ganglia.BlueFlare5059 (talk)16:30, 16 September 2025 (UTC)[reply]
The current version of the article has this paragraph in theGenetics section:
Natural selection has been acting against some genetic variants for ADHD over at least 45,000 years, complicating the suggestion that ADHD was an adaptive form of neurodiversity in the human evolutionary past.[1][2] The disorder may remain at a stable rate by the balance of genetic mutations and removal rate (natural selection) across generations; over thousands of years, these genetic variants become more stable, decreasing disorder prevalence.[3] During human evolution, executive functions disrupted in ADHD, likely provide the capacity to bind contingencies across time thereby directing behaviour toward future over immediate events so as to maximise social consequences for humans.[4]
I haveWP:MEDRS concerns with Keller 2008 and Barkley 2004 being dated, the former not being a review article, and the latter being the views of only a single author. At the very least, I am wondering whether we should attribute these claims. Aside from that, both sentences could use some editing.Xan747 (talk)16:03, 8 October 2025 (UTC)[reply]
The second reference is a Genomic analysis (2020) published in Nature, one of the most reputable journals available, in which they reached that conclusion. It is a robust reference. Keller (2008) and Barkley (2004) are not outdated unless significant evidence has since overturned their research. As for the latter being the views of a single author, this is not concerning as the publication has undergone peer-review whereby an external team of evaluators have examined the results and agreed with its contents.Димитрий Улянов Иванов (talk)13:53, 14 October 2025 (UTC)[reply]
@Димитрий Улянов Иванов, thank you for your response. I take your point about Barkley (2004) being a book chapter which likely did have some editorial oversight. There is a review of the book which I cannot now find that urged some caution about some of the chapters being leading-edge research. Though it did not mention Barkley's chapter specifically, the review did give me some pause. However, from the more recent citations given, there does seem to be support for positive selection pressure for ADHD-like traits in pre-industrial human society. To the hopper I add Barack et al. (2017)[1] Multiple authors, reputable publisher, reinforces other citations, probably also due for inclusion.Xan747 (talk)17:18, 22 October 2025 (UTC)[reply]
The statement that "the disorder costs society hundreds of billions of US dollars each year, worldwide" is in the lead but not substantiated in the article body. I've checked similar articles (such as the other 5 listed atNeurodevelopmental disorder as well asDyslexia) and none of them seem to have similar statements, althoughEpilepsy has a bit about economic costs under "society and culture", so I'm wondering whether the statement should be moved further down the article (in general the lack of any section on societal impact seems notable, so maybe this would involve creating that section), removed entirely, or kept as is.lp0 on fire (talk)21:01, 8 October 2025 (UTC)[reply]
Thank you for bringing this up.
@Димитрий Улянов Иванов I know we discussed this before, but this statement is not very clear, gives confusing connotations, and is not relevant to the article. Also, given the nature of mental disorder diagnostics, any change in its diagnostic criteria could potentially add or reduce the actual total societal costs. It should just be removed.Slothwizard (talk)23:13, 8 October 2025 (UTC)[reply]
It's a well-sourced factual statement so I'm not sure we should be quite so quick to delete something wejust don't like. It's currently worded to match the source, and the stuff about changing diagnostic criteria is probably not going to change the truth of wording as nonspecific as "billions", although that statement in itself is arguablyWP:OR. As for relevance, I think (as I mentioned above) that this article as a whole ought to have more coverage about effects on society. However, I worry that keeping this without other significant discussion of the effects on society could be non-neutral coverage. Either way, it has no place in the lead, so I'm glad to see you've deleted it for now.lp0 on fire (talk)08:07, 9 October 2025 (UTC)[reply]
No for the lede, yes for the body. If we withheld well-sourced and relevant information because not enough other stuff existed in its subtopic, nothing would ever get added.Xan747 (talk)15:19, 9 October 2025 (UTC)[reply]
Do you think I should create a "society and culture" section with just that statement in it and a "needs expanding" tag? I'm not familiar enough with the topic area to write the whole section.lp0 on fire (talk)15:36, 9 October 2025 (UTC)[reply]
I would addEconomic impacts as a subsection ofSigns and symptoms for now, and extract more from that source than just the worldwide economic impact. There is much relevant information on the financial burdens experienced at the national, individual and family levels across several nations in the11. What is the economic burden of ADHD? section of the paper to warrant two- or three-paragraph subsection, no tagging required.Xan747 (talk)16:52, 9 October 2025 (UTC)[reply]

Improving top-importance medicine articles: Join the Vital Signs campaign 2026
The goal of theWikipedia:WikiProject Medicine/Vital Signs 2026 campaign is to bring all 101 top-importance articles—including this one—up to at leastB-class quality. Many of these articles are widely read but overdue for review, so even small improvements can have a big impact.
If you watch or edit this article, your help would be very welcome. You can:
Add yourself as a participant
Note the state of the article in theProgress table (is the current class still correct?)
Update the article based on recent clinical guidelines and review papers
Help address gaps, improve clarity for a broad audience, or improve image selection
To reach B class, articles should have: suitable referencing, reasonable coverage, a clear structure, good prose, helpful illustrations, and be understandable to a broad audience. Contributions of any size are appreciated.Femke (talk)16:00, 20 December 2025 (UTC)[reply]
level-4 vital article is ratedGA-class on Wikipedia'scontent assessment scale.
