"individuals with autism have significantly reduced fecundity"

this came to me as a surprise, I've never heard of this before and can't seem to find any sources for it. I've looked at the references for that sentence and didn't find any mention of reduced fecundity, nor a "20 times less likely to have children" figure. should this passage be removed? StandardUser2 (talk) 16:34, 9 December 2023 (UTC)[reply]

this suggests significantly reduced fecundity (which, to be fair is not unexpected), thought I don't see the 20x figure. Black Kite (talk) 18:48, 9 December 2023 (UTC)[reply]

toxoplasmosis?!

I heard in recent years (on an NPR program) that the increasing rate of autism appears to correlate with the increasing popularity of cats as household pets (more closely than, say, vaccinations or thiomersal). Elsewhere I've heard that infection with toxoplasmosis has some correlation with autism. Toxoplasmosis is not mentioned under Autism or Causes of autism. Autism is not mentioned under toxoplasmosis or Toxoplasma gondii.

The Toxoplasmosis article says "Infection with T. gondii has been shown to alter the behavior of mice and rats in ways thought to increase the rodents' chances of being preyed upon by cats." It definitely modifies the brain, changing odor preferences, increasing activity, and reducing fear of predators, anxiety, and neophobia. Also: "Infections with toxoplasmosis are associated with a variety of neuropsychiatric and behavioral conditions." [in humans]. ((Or, Autism might be caused by something else that increases susceptibility to toxoplasmosis. Autism might increase exposure to toxoplasmosis and/or increase susceptibility to toxoplasmosis.))

(Of course, many other causes are possible, with varying degrees of speculation, such as allergens, lack of antigens, parasites, and lack of parasites.)

The idea of toxoplasmosis (and prenatal toxoplasmosis) correlated to autism is "out there" in medical and other literature. (Just search on "toxoplasmosis" "autism"; Google gets 646,000 hits; Google Books gets 4,050 hits; Google Scholar gets 5,750 hits.) I think it should be mentioned "in here". I don't want to do a sloppy job of it, though I might have to. (I wonder whether it has been added and removed in the past, but I have not checked for it.) -A876 (talk) 02:48, 5 October 2024 (UTC)[reply]

Can you find reliable WP:MEDRS sources to back any of this up? IntentionallyDense (talk) 04:32, 5 October 2024 (UTC)[reply]

Hi A876, the page already covers "infectious processes" underneath the "prenatal environment" section. Zenomonoz (talk) 09:08, 5 October 2024 (UTC)[reply]

Removing the bulk of the Causes section from the main Autism entry

At the moment, the main Autism article has many, many pages on causes, even though this entry has already been broken out. This redundancy is unhelpful, so I am proposing to remove the Causes section from the main entry.

In case anything is lost in this change, here is a link to the section as it stands. Oolong (talk) 19:10, 28 November 2024 (UTC)[reply]

Personally I wouldn’t remove the entire Causes section but instead just try to cut it down to one or two paragraphs. It may also be relevant to leave some of the content about the disproven vaccine theories since that is most likely (imo) one of the most relevant topics surrounding the causes of autism. IntentionallyDense ^(Contribs) 20:18, 28 November 2024 (UTC)[reply]

Yes, you're right - I shouldn't have suggested removing the section entirely, merely reducing it to a summary.

Here's the draft I came up with it - do you have any suggestions for anything else it really ought to include (besides references)? Two sentences might be a little on the short side.

Exactly what causes autism remains unknown. It appears to be primarily genetic. It is not caused by vaccines, nor by 'cold' parenting. Oolong (talk) 18:18, 1 December 2024 (UTC)[reply]

I think that there should be a bit more information about why we've come to believe that autism is primarily genetic and what that means—importantly, that it does not exclude environmental factors playing a role. I could see a section with three short paragraphs, one about genetic factors, one about epigenetics, and one about environmental factors. The conclusively disproven theories could be mentioned in a single sentence at the end of the section. I believe that prominently mentioning them gives them undue weight.--TempusTacet (talk) 19:04, 1 December 2024 (UTC)[reply]

Yep this was the kind of thing I was thinking about as well. IntentionallyDense ^(Contribs) 22:41, 1 December 2024 (UTC)[reply]

Yes, you're probably right that it warrants something a bit more. Would you consider drafting something on those lines yourself?

The vaccine thing, sadly, is still prevalent enough to be worth dismissing, however much or little we have on causes in the main entry! Oolong (talk) 17:39, 2 December 2024 (UTC)[reply]

Yes, I can propose a draft within the next couple of days.--TempusTacet (talk) 21:46, 3 December 2024 (UTC)[reply]

Excellent! Thank you.

Ideally we also want short summaries for other sections that have been replaced entirely with links to separate pages, but I see that as a relatively low priority... Oolong (talk) 11:42, 4 December 2024 (UTC)[reply]

Hey! Just wondering if you got anywhere with this yet? Oolong (talk) 13:57, 17 December 2024 (UTC)[reply]
