in which i make a thread because i expect autism research to get many comments.

not going to quote the whole article, but there's some new papers out on causes of autism.

basically, they attribute about 1/4 of the increase in autism diagnoses to changes in the diagnostic criteria, another 1/4 to a decrease in the age at which children are diagnosed with autism (from an age of 5.9 for children born in 1992 to 3.8 for children born in 2000), another chunk to increasing maternal age (and de novo mutations, that tend to accumulate as the mother ages) - and a great big chunk to, essentially, social networking, i.e., the odds of child being diagnosed increase the closer they live to a child that has already been diagnosed; they attribute this to parents sharing information. the effects are strongest in very young children and those with less severe symptoms.

they did not appear to look at the influence of being a fan of jenny mccarthy.

the article notes that ~ 1/3 of the increase is still not explained, but that means they have explained 2/3 of a 647% increase - which is a whole lot of cases, seems to me.

So what most researchers suspected winds up accounting for a chunk of it; changes surrounding diagnosis and awareness.
The accumulated mutations one is interesting. I suppose now the press is going to run a blurb about it and suddenly anything mutagenic becomes THE focus to the masses, rather than the bigger factors. Wait, isn't mercury a mutagen? CURSE YOU, THIOMERSOL!

yeah, except you vaccinate the kid _after_ it's born. although these people probably get their science knowledge from sci-fi shows on tv, where injecting some new dna will make over a person almost instantly.

i'm really interested in the social networking thing, because it makes perfect sense to me. you have one parent whose kid gets diagnosed, and they start describing all the symptoms and warning flags to the rest of the play group, and all the other parents start picking up on every little odd mannerism their kid has, and telling the doctor all about it - and there you have it, suddenly all these little kids are autistic.

it's like that thing medical students get, where they think they are developing every disease they study, except it's contagious.

So... Mark Zuckerberg caused autism?

This makes a lot more sense than it should. Could you please beat jenny mccarthy to death with your fists?

It's funny, 5 years ago I learned that the chance of being born with autism increased with maternal age. Apparently no one sought to find out if the average age of mothers was increasing until now? That's one of those, "Doh! Why didn't I think of that?" things.

Apparently, your mom caused autism!

man, UCSD is suddenly all over autism: the mutation causes a misfolded neural protein, so a new paper says.

and that's why it's important for mothers to fold things right

I thought we'd been over this?

We've known for a while that the average age of mothers was increasing due mostly to fertility treatments but also because people are marrying later (depending on how far back you go at least; there has been a change in the last generation for sure).

Now, it may be that no one actually put those two facts together in the same paper but it totally should have happened before now.

I'm betting people have, but this paper quantifies the phenomenon to see how much it explains the increased rate of autism diagnosis.

Scientifically speaking, if they've never done a factor analysis or a linear regression or some other form statistical prediction model on it... it's never been studied practically before this. Which is what I find kind of amazing. It happens all the time, though. Like, we knew that if you showed people a blinking field of letters and had one of the letters change with each blink that the time to search out the changing letter increased linearly in relation to the number of distractors, but no one ever thought to see if making the letter change color had the same relationship (sometimes research sounds boring, but this was judged to be really cool when it was presented at a conference).

This is a topic close at heart to me, so I hope you guys don't mind me being rambly for a minute.

They found out...what...18 months ago(?) that autism is a gene as well. Me and my wife and 2 kids are going to be genetically mapped as part of a study. Both of my children are autistic. They were diagnosed at 14 months due to a regression in verbal abilities. The woman that diagnosed them all but diagnosed me at the same time as being on the highly functioning side of the ASD spectrum.

They are now four, and speak very little using only a limited vocabulary of...maybe 10-15 words. They understand much of what we say, but speaking seems to be very difficult for them. They have been in a classroom based intensive autism program for over a year now, where they have access to specialists, other children their age with autism, other children their age that don't have autism (buddies they are paired up with so that the autistic children can see normal social behaviors) for 7 hours a day 4-5 days a week.

The program is amazing and it is free to top it all off. I live in an area that is considered to be the best place to live (literally) if you have a child with autism due to the wonderful programs that are here, and we are thankful of it. It's still hard to send my kids to school that much as I am missing out on much of their growing up that they are doing. Most parents don't have to put their kids on a school bus until their kids are 5-6. I started having to do it when mine were 2 and a half. The thing is that I know its the right thing to do. I'm a good dad, but I don't have the skill sets to give my children speech and physical therapy, or the social opportunities that my kids get at school. I just have to get the most out of their home hours.

My kids are amazing. They both have a lovely bubbly happy personality. One of them is quieter then the other, one of them is a trouble maker. They just don't talk much. There are other things that go along with autism, but for the most part that's the big difference between them and another four year old.

Sorry for the length, but I needed to say all that apparently.

just wondering, Falkonn -- are your kids identical or fraternal twins?
