Gut Microbes Linked to Autism-Like Symptoms in Mice
sciencehabit writes "Many physicians and parents report that their autistic children have unusually severe gastrointestinal problems, such as chronic constipation or diarrhea. These observations have led some researchers to speculate that an ailing gut contributes to the disorder in some cases, but scientific data has been lacking. Now, a provocative study claims that a probiotic treatment for gastrointestinal issues can reduce autismlike symptoms in mice and suggests that this treatment could work for humans, too."
They may need to find some other disorder to explain their anti-social behaviour and make them feel special.
Reminds me of when illness/death comes from some bad source of food and impacts a swath of people. It's always interested me to know how quickly and by what process the source is discovered. I know that when I feel weird and suspect bad food it's a bit of a challenge to think absolutely thoroughly back through every last thing I ate over the past X hours/days. I wonder if there are many other common threads such as this that might yield clues if researchers had more complete knowledge of every person with a particular condition including things that people may never mention thinking it isn't relevant or important.
Activiaaaaa...
You can hold down the "B" button for continuous firing.
Imagine the implications of an autism vaccine.
I, for one, am looking forward to the inevitable
That chick that appeared on Playboy said so!
Playboy, you say? I'd let her vaccinate me
As a nerd I assume that "Playboy" is some playbook-gameboy hybrid?
Does it want to watch Wapner? Can it count cards? We need to come up with a better way of testing stuff out than on mice.
I want to delete my account but Slashdot doesn't allow it.
Nonsense, it's obviously the vaccines! That chick that appeared on Playboy said so!
Don't worry, she'll go on national TV and apologize for all the harm she's done then spend the rest of her life making restitution.

Firstly, they discovered that the autistic-model mouse had very different gut biota and suffered from digestive tract issues. The new bacterium didn't establish itself, but it did perturb the gut bacteria community to be closer to control mice, and reduced digestive tract issues.
Secondly, they discovered that this perturbation reduced the autism-model symptoms in the autism-model mice quite markedly.
Thirdly, they discovered a gut metabolite that was elevated in untreated autism-model mice versus control mice or treated autism-model mice. However providing that metabolite to control mice only caused an increase in anxiety behaviours, and not the specific autistic ones. So it's not just the metabolite which is responsible for the behaviours.
I wonder if there's some underlying difference in the neurology of the autism-model mice such that the metabolite "sets off" the autism-model behaviours rather than anxiety. Or perhaps the metabolite causes anxiety in both communities but the anxiety only then "sets off" the autism-model behaviours in the autism-model mice.
No kidding!!! What do you say at this point?
Autism is genetic and is also influenced / is a function of the environment they are brought up in
Did you consider that it might not be passed on through DNA at all, and completely is a result of the environment, including the bacteria that your mum's side of the family have in their body? Or perhaps your DNA makes you more susceptible to these bacteria. I've been trying to figure out how exactly food affects my mood and behaviour for a while now..
which is totally what she said

Did you consider that it might not be passed on through DNA at all, and completely is a result of the environment,
I would be inclined to say that you do not know a lot of people with a history of Autism in the family.
As I said, it is genetic, but is also environmental, It can be from a singular source, genetic or environmental. At the end of the day it is about how the brain is wired, Its psychological at is its foundation. Eat healthy and have a varied diet, keep away from the junk / fast and sugar filled foods, drink lots of water etc. Plus a good amount of contructive socialising is the best recommendation.
Isn't this the same thing Wakefield was trying to prove before he committed research fraud and started the whole "vaccines cause autism" nonsense?

"Probiotic" is the little Shibboleth that makes this smell like woo.
If poop transplants can drastically improve health, why couldn't regulating your digestive system with probiotics? Yogurt is a probiotic. It has proven related health benefits. You're FUDding. Are you invested in Big Pharma? Or are you just being a dick?
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Sure, that's what science "knows" about it so far, but the idea that gut bacteria are a deciding factor also fits perfectly along with your "genetic or environmental" concept. If all you have is a hammer (genetics, environmental observation) then everything looks like a nail. Maybe there's more to it than bacteria, but the chemicals that we put into our body very obviously can affect behaviour and mental state.
which is totally what she said
Poe.
Of course gut microbe play a role. Some aggressive species are able to attack the gut's cells, which cause the leaky gut syndrome, where food proteins not completely digested can enter the bloodstream. The immune system will seek and destroy them, every day, on every meal. That can trigger allergies and autoimmune diseases.
Moreover proteins from milk and wheat contains sequences that are hard to break down, and that can activate morphine receptors in the brain. They are called caseomorphins and gliadomorphins. Some (but not all) autists have success in reducing their symptoms by adopting a diet without diary product and gluten, and it is suspected this is for that reason.
Irritation causes inflammation. It might appear to be a disease if you can't figure out what is causing the irritation.
which is totally what she said
It not only addresses the role bacteria plays in autism, downs, etc
Daft question: If she has all the answers - why is there research still being done?
Environmental bacteria might not be the only factor, bit I think gut bacteria is indeed worth looking into. I remembered an article I read a few weeks ago about infants possibly suppressing their immune systems to let in "good" gut bacteria. Well, what if they also let in some not so good gut bacteria that leads to Autism? Doesn't Autism usually start to show during very early childhood?
At the end of the day it is about how the brain is wired, Its psychological at is its foundation.
If it's about how the brain is wired, then it's neurological, not psychological. Autism is generally classified as a neurological disorder.
If autism turns out to have a microbial cause, the actual treatment might be a vaccine. If this happens, would anti-tech hippie heads explode?
A common symptom of autism is a lack of tact. So the rude delivery of their pronouncement might back up their claim to be autistic.
;D
Didn't you hear? She cured her son's autism using a gluten-free diet and some other nonsense that you can probably read about in her book. Yes, Playboy Model cures a developmental disorder that scientists don't even have a complete understanding for yet. She must be a genius!

(Disclaimer: Both my son and I have Asperger's Syndrome/High Functioning Autism and claims that someone is going to "cure" me or my son are just insulting. A treatment to alleviate symptoms for the folks on the "low functioning" end of the spectrum maybe, but curing someone implies that there's something wrong with that person and I don't see Autism as "wrong", just as a different way of thinking - one that happens to come in very handy at times.)

I know people who have made great strides is the symptoms of their autistic children by changing their diet and especially cutting out gluten. I thought there was already a known connection between the gut bacteria and autism. Oh, well. Sometimes it takes the mainstream a while to catch up on what some people are figuring out.

I think the need to label it as coming from Vaccines/antibiotics/whatever also comes from the lack of control parents feel as well. Their child isn't developing "normally" and, if it is genetics, they would have been unable to have stopped or prevented this. If the problem is that vaccines (or some other completely unproven factor) is to blame then if they only did X or didn't do Y, their kid would be "normal" and they can "help" other parents by advocating for/against that thing.
There's a post going around social media (that I refuse to link to) called "How I gave my child autism" where the author blames herself for all of the things she did which "gave" her child autism from ultrasounds to vaccines to having a C-Section. The level of woo in that post is very high as the author seems determined to make Jenny McCarthy look scientific in nature.
In my case, we got the diagnosis on Asperger's Syndrome/High Functioning Autism on our oldest son after years of trying to figure out what was going on with him. As we read book after book on Asperger's Syndrome, I realized these books were describing me as well. I haven't been diagnosed mainly because 1) it costs money we can't afford to spend, and 2) my diagnosis won't help my son at all. Still, I'm convinced that I have Asperger's Syndrome and "gave" it to my son via genetics. (Yes, I went through a period of feeling guilty for this even though I knew intellectually that this wasn't something where there was blame to assign.)
On the subject of the gut bacteria issue, my guess is that discomfort from the gut bacteria problem exacerbates autism symptoms. Treating the gut bacteria issue doesn't cure autism, but does reduce discomfort which lets people with autism cope with the neurotypical world better. To neurotypicals, this looks like autism is being cured when it's just being "hidden" better.

its genetic and or environmental ... there is a history of Autism being blamed on whatever is convenient to blame it on
Which is it? Is autism a real neurological condition, caused by genetic and/or environmental factors, or is it a BS diagnosis used to excuse poor parenting?
there is a history of Autism being blamed on whatever is convenient to blame it on, rather than addressing the real issues, which when you get down to it, is about supporting the person in question, so they are more able to interact with people on a normal level
So having autism per se isn't a real issue? It's not neurological? Or is it such a mild neurological condition that the only "real issue" is "supporting the person in question"?
Your autism is mild. It may cause you anxiety, social difficulties and whatnot, but so can a million other things. If the spectrum went no further than your level, it would be a diagnosis of questionable value, and it wouldn't be more troublesome, or more difficult to treat than anxiety, social difficulties (oops, disorder), etc., not associated with an autism diagnosis.
Don't talk about your situation as though it had much to do with severe autism though - the kind where many of its sufferers can't speak, may have compulsions so severe that they cause severe bodily harm to themselves, and can never be left unsupervised. Comparing your condition to that is like comparing feeling a little blue to being so depressed you're about to jump off a bridge. Stop acting as though your situation allows you to speak authoritatively about the entire autism spectrum.
I am not the asshole, the real assholes are the parents who do not provide the required support to their kids and their answer to their kids behavioural issues is to keep them constantly duped up on ritalin and always look to blame it on something, rather than providing a healthier environment for their kids.
Whose experience are you talking about? If it's yours, then unless you were seriously abused and neglected, stop feeling sorry for yourself and blaming your parents for all your problems. If you're talking about others, I find it hard to take it seriously. "They're bad parents" is the oldest catch-all way to explain what you don't understand. With autism "blame the parents" has a particularly illustrious history, dating back to the old, damn science and pull a "psychological explanation" out of your ass, refrigerator mom theory.
their answer to their kids behavioural issues is to keep them constantly duped up on ritalin
Ritalin is generally used to treat ADHD, not autism. Risperidone is the most common pharmaceutical treatment, and also the only medication for which autism symptom treatment is an on-label use.
It would be nice if you used some name other than "Anonymous Coward" if you want to participate in protracted debates. If you're the OP though, and claim to also have an ADHD diagnosis, I agree that ADHD is a very questionable and certainly wildly overused diagnosis. Hence its "treatment" is often questionable. ADHD is not autism.
There's already a good lead that amino acid supplementation may cure a certain rare form of autism, but there are many different causes. It's important to note that the study wasn't done on humans (research ongoing), and the type presents with intellectual disability (retardation) and epilepsy.
So the above doesn't actually treat "autism", it treats certain debilitating aspects of it. The personality nuances may still be intact after treatment, we don't know for sure yet.
In the study we're discussing now, "autism-like" was a good choice of words. We're not actually certain the mice had autism: they simply displayed symptoms that scientists concluded were autistic.
In the end autism isn't studied enough to make any definite conclusions about anything. On a more philosophical note, however, imagine if there were an introvert vaccine that turned introverts into extroverts. Perhaps we're closing in on a point where we can alter people's personalities, which has some wide implications for the penal and mental health systems.
Actually, Autism is a developmental disorder. For example, my son with Asperger's Syndrome/High Functioning Autism is ten years old. Socially, though, he's about six. (Coincidentally, the same age as his younger, neurotypical brother.) Intellectually, though, he's about 12 so teaching him can be very challenging. He'll grasp concepts quickly, get bored, and engage in socially inappropriate behaviors that someone years younger than he is would consider funny. (Thankfully, many of his peers understand about his Autism. Wish I could say the same about all of his teachers.)

... about the gut, you always wonder if scientists are giving you the straight shit.
Word. My daughter and I are aspies, and I see no reason for a "cure." That being said, the autism spectrum is pretty broad, and anything that could help alleviate the more severe issues associated with it would be tremendously beneficial.
Considering that most of the cells "inside" the body (if you don't think of the human system as a torus)
are non-human and form an entire ecosystem that digests nutrients out of the substances we ingest,
it makes sense that good digestion is as fundamental to us as it is to a tree (which also relies on an exterior soil ecosystem).
This would also coincide with the apparent disease-like spread of autism thru the population.
The spread of autism also displays a flavor of inheritance and we aren't completely sure how gut bacteria spread
but it's likely that you get it from the people you spend the most time around.
Playboy: Entertainment for Men is a monthly magazine that's essentially The New Yorker with more pictures of naked women. Nintendo would never allow that sort of nudity on its platform. I just checked App World, and Playboy doesn't appear in the magazines section, nor does Playboy appear to have a Kindle edition. Feel free to prove me wrong though.
Playboy Model cures a developmental disorder that scientists don't even have a complete understanding for yet. She must be a genius!
If she has a book full of easy-to-follow pictures, I'd probably skim it.
You know, just for the medical value.
My son who is autistic started talking and became much more relaxed after cutting milk out of his diet. This was when he was in grade 1 and had only a couple of words and often became disruptive enough in class that he needed 2 strong men to remove him from class.
Afterwards the odd time when someone did feed him diary I could tell right away by how he was acting out. Eventually his IQ also went from 80 to 120 except in communicating (speech and writing) where it stayed at 80. Not a cure but it sure improved his capabilities and functioning.
Note that ethnically he is of stock that has no lactose digesting history so like the majority of people in the world should only have minimal diary anyways.

My daughter and I are aspies, and I see no reason for a "cure."
Other than perhaps widespread discrimination by interviewers against people who show symptoms during the interview?
It's not ignorant to think that food plays a role in bowel problems. There are many recognised conditions that are aggravated by certain foods.. so to think that simply taking a pill, but continuing to eat any old shit is a good way to treat it.. that's pretty a pretty ignorant way of looking at it.
Going on a low carbohydrate diet a few years ago (to lose weight) cleared up several other problems that I wouldn't have even related to diet at the time (such as my nose almost always being irritated and blocked).
I don't need to lose any weight right now, but after reading this thread, I'm thinking I'll go back to no carb again for a while and see how it affects me.
which is totally what she said
Well the original theory was that the combination of 3 live vaccines given to the very young overloaded part of their immune system and screwed up their guts. The fix at the time was considered to be splitting up the MMR vaccine into 3 shots spread out a bit in time. I was quite interested as my son was one of the children who coincidently stopped talking and started acting different in the week following his second MMR shot. I'll also note he has had very rank farts most of his life.
Later the weirdos with their mercury fetish became very vocal.

There is a vast difference between fecal transplants and the "probiotics" that you find in the healthfood section of your local store. The key difference is that one has been proven to work in rigorous and repeated scientific study, and the other has not. That said, I think what TFA is talking about is closer to to a fecal transplant where existing gut bacteria are cultured from the control mice and transferred to the model mice.
And before you ask no, I'm not heavily invested in big pharma. I am, however, a well read dick with digestive issues and access to journals.
I browse on +1 so AC's need not respond, I won't see it.
That was what stood out to me. They noticed that the mice weren't as social, but they don't know WHY. I can't personally speak for the lower-functioning end of the Autism spectrum, but on the high functioning end (i.e. Asperger's Syndrome), the autistic individual WANTS very much to socialize, but literally doesn't know how. They can figure out how and "emulate" neurotypical enough to carry on conversations, but this is taxing on them and they can't keep it up forever without needing time to decompress. Like how an emulated application never runs as fast as a native application. Neurotypicals run "socializing" as a native app. Aspies emulate it (with varying degrees of success).
Add in the fact that Aspies can be so afraid of making a mistake while "emulating neurotypical" (possibly insulting someone) that it is easier and safer to just not interact at all. To the outside world, it looks like Aspies just are anti-social and would rather be left alone.
So maybe the mice really did want to socialize with other mice but didn't know the mouse social protocols that other mice knew instinctively. Or maybe there was another reason for their lack of socialization. At most, this might lead to treatments that remove some stumbling blocks which prevent autistic individuals from functioning in the neurotypical world. Not all stumbling blocks, but some of them. If it's a treatment that helps autistic individuals, great. If some woo folks grab onto this and start claiming to be able to "cure" autism by following their woo diet, very bad.

If you had a structural defect, like a broken arm, and I prescribed yoghurt... You'd be pretty pissed off that I didn't tell you it was just calcium you needed and that I didn't mend your arm. You should be equally upset if you had a mental structural defect and I told you to go eat shit.
I have a grandson with autism, and his family is always joking about his rank farts. I never thought I'd be writing about farts on slashdot, but maybe there's something to this.
One used to be able to make the "office harmony" argument against hiring people of the wrong skin color until the enactment of civil rights legislation. It's just harder to prove autism discrimination than racial discrimination in court.

And what's wrong with that? Don't forget that science is bogged down by belief. I also 'cured' my autism through diet and other 'nonsense'.

Oh grow up already. A cure doesn't mean you lose who you are, it means you discover more of who you are meant to be. Of course, most people, like you, are too scared shitless of being anything besides what they know and are comfortable with. Don't let your fears, biases, and beliefs affect your son, that would be more detrimental to him than any 'cure' could ever be. A point of view is only useful if one recognises it as just one tool in a full toolbox. If you can't change viewpoints at will then it is not a positive in your life, it means your reality is constrained. This applies to both NT's and autists.

What if some day the "Hollywood model" is proven right?
I can think if a lot of entrenched "medical certainty" that has been overturned, and it seems to just morph into everyone "at the present time" believing in the infallibility of modern medicine.
Really, "modern medicine" is just a results based commercial hodge-podge that is only slightly better than the days when "modern medicine" was giving people bloodletting and mercury.
There are a few really good things like Penicillin that make up the bulk of "modern medicine's" success, and then there is a lot of cough syrup. It's only in the past decade I think they started treating ulcers as problems of bacteria and not problems of stomach acid.
Medicine is the last damn field that can pretend to have a real understanding of what is going on. If you took away plumbing, good food handling practices and refrigeration, people would be dropping like flies just as they were BEFORE modern medicine.

There is a strict diet called the GAPS Diet that both of these families followed and they began to see substantive changes within months, and ongoing improvements over a couple of years that have really allowed these kids to blossom.
This is not hearsay. I knew these kids before and I know them after, and they have improved dramatically.
There is a vast difference between fecal transplants and the "probiotics" that you find in the healthfood section of your local store.
Yes, that's true. The former is for use in emergencies. The latter is what you use to avoid getting into an emergency situation. Because as it turns out, your intestines are possibly the home of your immune system in a very real way. Your gut bacteria turn out to be very important to immune defense, and what you eat has a direct influence on your gut bacteria. In particular, eating a lot of sugars feeds the harmful organisms and permits them to outcompete the beneficial ones.
The key difference is that one has been proven to work in rigorous and repeated scientific study, and the other has not.
Yes, that's what the FDA says about anything that hasn't undergone tests which check their particular boxes, whether they're good science or not. I have looser standards than they do. Also, I don't actually trust them. In this case the EU health cocks say the same thing, but that's no different really.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
I have a tip for you then, you probably don't need to go 'no-carb'.
I stopped eating wheat and dairy for bowel problems. I replaced wheat with spelt (different grain) for bread, cookies, pasta etc. And not only did it for me also solve nose issues as well as the bowel issues, I also lost the 20kg weight I had gained since my early twenties.
I personally believe that in stead of no carb, people should go with the right carbs.

Maybe you don't have Asperger's at all; maybe you're just an asshole.
You might want to read Gut and Psychology Syndrome | GAPS Diet by Dr. Natasha Campbell-McBride. Some doctors in the UK and US are using this approach to treat autism with good results, but there no published studies that I'm aware of. The main focus points of the book are probiotics (like kefir) and eliminating artificial additives (e.g preservatives, colours & flavours), gluten and casein.
Friends with autistic children have noticed improvement by following the book, but as others have said autism is complex and not fully understood. We've noticed significant behavioural improvements, eczema cured and disappearnce of mystery ankle pains in our own non-autistic kids by eliminating presevatives, especially 282 found in many bread products. I wouldn't consider it scientifically proven but since the cost is minimal and risks (almost) non-existant, I would recommend trialing a GAPS diet.
Probiotics are now recommended by some doctors to restore gut health after a course of antibiotics.
What if some day the "Hollywood model" is proven right?

Exactly. Even if some study came out tomorrow proving beyond a shadow of a doubt that Autism was caused by vaccines (and leaving out the fact that such a study would require a LOT of double and triple checking before it would be accepted), I'd still support the use of vaccines. Better to have a live child with autism then a neurotypical child who dies of measles, whooping cough, polio, etc.
