Scientists warn of chemical-autism link

Autism and environmental health experts called for greater scrutiny of chemicals found in the environment, which could potentially lead to autism and other neurodevelopmental disorders, in a conference call Tuesday.

"We live, breathe and start our families in the presence of toxic chemical mixtures and constant low-level toxic exposures, in stark contrast to the way chemicals are tested for safety," said Donna Ferullo, Director of Program Research at The Autism Society.

"Lead, mercury, and other neurotoxic chemicals have a profound effect on the developing brain at levels that were once thought to be safe," she said.

Autism spectrum disorders are being diagnosed at unprecedented rates, partly because of improved diagnostic tools and criteria, but also a host of other factors including what mothers-to-be are exposed and consequently their unborn children too, said Irva Hertz-Piccotto, Chief of the Division of Environmental Health at the University of California, Davis, and a faculty member at the Mind Institute.

About 1 in 110 children in the United States has autism, a group of developmental disorders that lead to impairments in behavior, communication and socialization. The cost of autism is staggering: $3.2 million for the care of a person with autism throughout his or her life; behavioral therapy can be hard to come by and be very limited,  and most medications don't help much.

Studies have strongly suggested a genetic component in the cause of autism, but it's becoming clear that genetics alone isn't the whole story; there could be interactions between susceptibility genes and environmental chemicals.

Recent research from her group, appearing in the journal Epidemiology, showed that prenatal vitamins taken prior to conception seem to interact with certain metabolizing genes that are inherited.  Those women who did not take the vitamins, and had the high-risk genotypes, were more likely to have a child with autism.  Still, this was a small study limited in scope, and more research should be done to confirm these findings.

The central nervous system of the fetus is sensitive to a wide range of chemicals, Hertz-Piccotto said.  Hormones, such as estrogens and androgens, are essential for proper brain development. Endocrine-disrupting compounds need more research, she said. Flame-retardant chemicals called PBDEs interfere with the body's hormones.  Even though many of them are no longer used in manufacturing, they can hang around in the environment and the human body for a long time.  The Environmental Protection Agency (EPA) is aware of concerns about these chemicals and is working on accessing substitutions (see the action plan).

Bisphenol A, present in plastic food packaging and water bottles, among other products, is another big concern, she said, because it could interfere with the body's natural estrogen system; antimicrobials added to soaps, toothpaste and other products can artificially enhance androgenic activity.

"That means that they could potentially play a role in autism or other neurodevelopmental disorders," Hertz-Piccotto said.

Moreover, many children with autism spectrum disorders have abnormal immune responses. The chemical messengers in the immune system interact with the receptors in the brain, so chemicals that affect immunity could also be implicated in autism.

Thyroid dysfunction is common in children with autism that psychiatrist Dr. Suruchi Chandra sees, even though that's not part of the classical symptoms of the condition.  She believes the abnormalities are due to the thyroid hormone disruptors such as BPA and flame retardants.

"Thyroid hormone is critical for brain development in early life, and even small alterations in hormone levels can have serious consequences; long-lasting and perhaps irreversible consequences in terms of brain function," she said.

Air pollution from traffic and certain pesticides have also been shown to have associations with autism, studies have shown.  Maternal conditions could partially result from chemicals in the environment.

Andy Igrejas, National Campaign Director of Safer Chemicals, Healthy Families, called for an update of the 1976 Toxic Substances Control Act. Sen. Frank Lautenberg (D-NJ) has proposed a stricter version that would require all industrial chemicals to be tested for safety.

UPDATE: Since so many of you have asked, I wanted to clarify that this discussion does not relate to vaccines. The scientific evidence available has shown again and again that vaccines do not cause autism.

    Would like to see the rate of autism among poor americans vs middle class. Growing up poor we had very limited exposure to baby stuff... we didn't even have diapers, parents used rags and then washed them by hand...no detergiants..no bottles, no plastics per se, limited exposure to ALL the chemicals that surround mother and child, not even a car or car seat LOL Not even dish soap, just hot water. Man I was poor! Haha!

      autism is actually much higher in children of highly educated, well off families. however, this could be due to better access to healthcare...there has yet to be a definitive study proving which is more correct

      Unless you live downwind or downstream from a chemical plant or coal slag heap, you are probably much better off without all the plastics etc. that we expose our kids to. Don't forget dioxins too: these are found in bleached paper (such as toilet paper), and dioxins are proven to cause women's reproductive problems, which can affect the fetus.

Do people not also get that Dr. Wakefield has been totally discredited and his study proven to be massively flawed and fraudulent ....the ONLY study to show a link to vaccines?? People who perpetuate the vaccine myth are just people who don't want to believe that autism is genetically-based and that there are other things causing this that they might not want to give up or acknowledge.

      Raevyn your an idiot. Go pick up a textbook and do some research and stop spewing nonsense. The autism rate has gone up about a hundred times in the last few decades. Genes don't change significantly over a few decades. 99% of autism is environmentally caused. That is fact. The only thing up for debate is what is causing it. How does it feel to be a stereotypical brainwashed product of the media without a mind of your own?

    It's too bad the comments went the vaccination route. The problem is chemicals in EVERYTHING. Our bodies are not bio filters. Chemicals proven to be harmless in tiny amounts are acceptable, but we are constantly bombarded from the shampoo and soap, the water, the food. We consume and spread on our bodies a toxic soup every single day of our lives from birth. People don't realize what power they have, quit trying to blame and have someone else take responsibility. STOP buying those products, you as a consumer have infinite power to put a stop to this, because in the end, it all comes down to profit for these companies, and you have the money they want.

      Cheryl, I have to agree with you. As a healthcare professional, it is extremely disappointing to see how the media can spread false and dangerous views. It is obvious to me that our environment is 100 percent linked to these issues. If parents stop vaccinating their children in the US, I assure anyone that death my PREVENTABLE and life-threatening disease will outweigh any debate on the linkage between vaccines and autism. While there may be some debate between the linkage between vaccinations and autism (which lacks scientific evidence), there is direct evidence to support the linkage between these serious illnesses and death when not prevented.

      You know, I'm on the fence about vaccines causing autism (diabetes, ADHD, and the many other things afflicting our children), but it does have some compelling correlations when you consider the sheer number of people who's kids have had reaction directly after the vaccine. Read enough stories, articles, and peruse the vaccine ingredients lists and side effects and it is pretty bone chilling. (Funny no one has mentioned Aluminum, or the fact that the Hep B shot is given at birth and why). Also, interesting is SIDS...a diagnosis without a cause (and I don't buy the 'they just died.') Something clearly had to have caused it. I wish people would stop bashing each other on their decisions, made by parents in what they feel is the best interest of their child, and start working more towards finding answers together. I have no idea what those answers are, but I do adhere to the policy of doing what is best for myself and my family, which means avoiding certain chemicals, seeking out the better options in household items, personal products, detergents, organic fertilizers, sunblocks, and yes I am one of the 'idiots' who buys into the organic food 'scam.' My kids are mostly vaccinated. Will they have more?? I don't know. I will continue to read, and try and educate myself as best as I can... Hate mongering has no place in this debate and it absolutely makes me sick to read comments by people who think they have all the answers and bash those who have a different view. We won't get anywhere treating each other like morons.

    I agree with Laura 100 percent. I am the mother of Autistic sons born in 1986. They were vaccinated as were their two older sisters .The bottom line is we now have a NATION of these children and the numbers keep going up. My sons contracted scarlet fever also...something from the 1800's.

      Scarlet Fever is caused by the strep bacteria. There's no vaccine for it. But I get your point, and I agree. My niece contracted whooping cough – her mother refused to vaccinate them.
      Three years ago my oldest daughter was diagnosed with P.A.N.D.A.S. She was 6 at the time, and all of a sudden displayed dramatic OCD, ADD, ODD and autistic behaviors. With long-term antibiotic therapy she's fine now. I mention this because there's been an explosion of PANDAS research recently that has begun to dovetail with some autism research. Some children's immune systems go haywire when exposed to some illnesses (in the case of PANDAS, it's strep throat) and begin to attack their own brain. They're finding out that similar mechanisms may apply to some autistic children. I wouldn't be surprised if they eventually determine that some autism is triggered by an autoimmune reaction to some vaccines. To be clear what I'm saying – there's nothing wrong with the vaccines themselves, they prevent deadly illnesses. But some kids have immune systems that get their signals crossed, like my daughter. And maybe environmental chemical exposure affects a person's susceptibility to autoimmune disorders. I don't know – but it sounds very plausible to me.
      We do vaccinate, but after my daughter's diagnosis we never do more than two at a time (for all of the kids, just out of an abundance of caution).

      There is no well accepted scientific evidence to show that vaccines cause autism! Spouting off this myth only confuses the matter and distracts from the discussion of what really causes autism, which is open to debate. Vaccines definitely help many people, yet the anti-vaccine crowd focuses mainly on the myth that they might cause autism and confuse folks who are wondering about vaccinating their children.

      Vaccines are another chemical. It's not ONLY the vaccines that cause autism. It's the chemicals from the vaccines added to the chemicals in the food, and the furniture, and the air, and the water, and the plastic toys and bottles, and the clothing. Little bodies can't handle all of those chemicals. I am not anti-vaccine but vaccines are done too young. Keep the kids as chemical free as possible and do the vaccines later, when the kids are stronger!

      Well I have a child with Autism and I know it was vaccine related. Right after her vaccine when she was 5 she developed the symptoms of autism, prior to that she was 100% happy and healthy! I also know another mother who has twins and when she got there vaccines done, walla, they both developed Autism right after as well, the vaccines were from the same batch. It is the Mercury that prolongs the shelf life of the vaccine that causes it and depending on how long it's been on the self will increase your chances of your child developing autism. I don't know anyone who has Autism run in the family, I don't have it on either side!

      Unless you have a child with Autism and have done the reseach, you shouldn't be commenting and saying it is not the vaccine. I have a medicat doctor who actually agrees with it as well. I also have had my daughter to a Natural Path who does blood anaylsis and she's confirmed as well it is the mercury in the vaccine and it's actually caused damage to my daughters right kidney as well.

      You won't find this anywhere else in the world, only North America. The pharmacutical companies make billions and billions by keeping people sick, so why would they fix it! using anything chemical base is a disaster for our health, we need to go back to good ole fashion medicines and cures!

      Have many people commenting actually read any medical journals and current research going on in this field? Not just an occasional acticle on CNN.com or blip on the nightly news? For example, did you know that researchers are now linking one form of diabetes to a specific virus? Yes, caused by the virus. Not crazy, outer-edge scientists, but mainline researchers. There is a theory that the same may possibly be true of autism. Thermisol, mercury and aluminum add to all of our toxic load, but there is a possibilty that the actual virus in the vaccine could be the problem. That it triggers a T2 rather than T1 immune response in our body, starts a chain reaction of autoimmune response and a host of biological problems. It's worth reading beyond a news website and acutally reading science journals and leading research before you assume or comment casually (and cruelly at times). And with the number of people who say their children seem to disappear after the MMR, these people aren't making this up. That doesn't mean we know exactly what the connection is, but when there are repetive cases connected to the timing of a specific vaccine, why wouldn't we look further for any connections/answers? It would be illogical not to search for any connection. Do I think vaccines are the primary problem? I don't know. But it's not just genetics – that's obvious. There is no such thing as a genetic epidemic. And it seems illogical that the increase is primarily due to better screening & diagnosis. The DSM manual published in the late 80s/early 909's actually narrowed the requirements to qualify for an autism diagnosis (not broadened them). So the numbers should have actually gone down, yet they are skyrocketing. If it was truly just due to better diagnosis, then there would be this silent mass of teens and adults with autism whose family never requested or received evaluation & serivices. And I guess they would have had to keep those hidden millions at home instead of in the school system, because they wouldn't have made it through school non-verbal, or hyperactive and stimming, unable to attend tasks or communicate due to lack of any form of treatment. I think this article handles the issues well – there is probably a multiple hit issue going on. Genetic weakness (not cause), environmental triggers or toxic tipping point. There are consist biological issue for kids with autism: immune dysfunction, mitochondrial dysfunction, frequently deficiencies in Omega 3, Vitamin D, Iron, etc. There's a whole lot going on here. But – if you don't have a child with autism and you aren't a researcher, think twice before commenting so casually and often cruely. You have no idea what life is like for these parents. And read up a little more while you're at it.

      Lucky, You need to read some scientific journals yourself. Yes, Type1 diabetes IS an auto-immune problem and has been classified as such for DECADES. They have recently the likely cause of type-1 diabetes to a virus that casues the common cold. Some people can't fight it off effectively, and the virus splices itself into your DNA.

      To make a claim that the Virus in the vaccine could be responsible for autism makes you just ignorant as anyone esle you criticize...because they don't give you a live virus in vaccines. Your body won't attack itself because your cells aren't infected with the virus. If you do YOUR research, you will find that they have had a high success rate predicting autism in infants with series of behavioral tests. That's means they are able to detect signs of autism LONG before the vaccinations occur, which means that the vaccination is not the cause.

      I agree. Just today, I saw another "Study" that said that prenatal vitamins reduce the risk of autism by 50%. That certainly seems to contradict the assertion that rich people have a higher incidence even though they are the most likely group to take prenatal vitamins.

      The real problem is thatthese junk scientists look at data, see and trend, and report it as fact. If you use REAL scientific methodology, these trends would merely be basis of a hypothesis. If your hypothesis is legit, then you should be able to predict the results in future programs/experiments, and other unbiased scientists should be able to reproduce your results. Too bad the world doesn't work that way.

      Somebody sees a trend in some data, which does not prove cause and effect, then they shoot it out to the media who presents it as fact to the simpletons.

      Also, nobody ever mentions that they modified the definition of Ausitm a few years ago to include Aspergers Syndrome and several other "disorders" that were not previously considered "Autistic." The collection of these disorders is now know as ASD, yet people are quick to say "Look how the number of AUTISM cases has suddenly risen".

      Why should we believe that there is one single cause for various "disorders" that have only recently been assigned a common label. Obviously, there is enough difference in these syndromes and disorders to name and diagnose them differently.

    So, mercury has a profound effect on the developing brain but vaccines with thimerosol, which contain mercury, don't cause autism.

    Sy2502, call me a simpleton but at least I researched vaccinations before making my decision not to vaccinate my children. You may think there is no link, but I'll bet you don't know a family whose child changed immediately after receiving immunizations. I do. The change was dramatic and stunning.

      Exactly. My son was on schedule with all of his developmental milestones even though he was born very prematurely. When he received his MMR vaccine at age 18 months, he suddenly stopped talking, lost all language, all eye contact, etc. Do I believe genes and environment are a factor? Sure, but the vaccines are part of the puzzle, 100%. If you don't believe me, come on over and check out my family photo album. You can SEE the difference in my kid. From the happy giggling baby covered in spaghetti head to toe...to the baby who tipped his toy cars over to stim over the spinning wheels.

      Just because something "contains mercury" does not mean its harmful. This is fundamental chemistry. Mercury in one molecular form can be harmless, while in another form deadly. The biochemical interactions with the body are what matter and the studies say the vaccines are safe. You are wrecklessly putting other people's children as well as your own children at risk by not giving them vaccinations. Furthermore, any contraction of a disease by the unvaccinated can spread throughout the population and cause death. Imagine if some people had refused the smallpox or polio vaccines years ago, those diseases would still be running rampant. The point is, please put aside your conspiracy theories for the sake of your children and the rest of us.

      The Thimerosal-autism link has been conclusively debunked. Influenza vaccines aside, As of 30 Jan 2007, none of the vaccines routinely recommended for children age 6 or younger contains Thimerosal. There are Thimerosal-free versions of Influenza vaccine available, and those that do contain that preservative have it at 0.01% concentration (roughly 50 micrograms per milliliter; one dose is typically 0.25 or 0.5 milliliters). Despite this the US is not seeing any decline in the rate of diagnosis of autism spectrum disorders.

After the remove the aluminum, the conspiracy theorists will complain that it's the needle itself. Or maybe it's the phase of the sun when the vaccine is administered. These conspiracy theorists are a bunch of junk "I think I know it all scientists" because they read a couple of articles on the internet. Truth is no one knows the cause of autism, period.

      Since children's vaccines are administered during the same developmental time/age, the argument that vaccines cause or contribute to ASD or Autism isn't the most logical one. Many genetic disorders occur in patients the same age.

    My son is autistic. I have no idea what caused it. What I do know is that we have made kids virtual pin cushions with vaccines and all decisions carry risks. We are over vaccinating our kids. We now even give kids vaccines for chicken pox and HPV. C'mon, It is one thing to protect against polio, measles and WC, but HPV and chicken pox. When does this end? Also, we give kids a dizzying array of vaccines at a very early age. In many cases shots are combined on the same day and or mix may many viruses. Why do we need to assault an immune system in this way? How about spread the vaccines out, one at a time? The reason (I have been told) is that docs and public health authorities are trying to assure compliance and spreading things out leaves open the possibility a patient will not return for future appointments. No one gets sick with mumps measles rublella polio and whopping cough on the same day in the real world. Our kids deserve better than that kind of fast food medicine.

      The immune system is assaulted constantly by bacteria and viruses in the environment. It's designed for constant assault since bacteria are everywhere and on everything! I doubt the immune system cares whether its fighting against measles or just another cold virus or bacterium. It never takes a break and certainly doesn't expect people to wait a few weeks in between exposure to the next bacterium that might try to invade the body. It's designed to handle multiple invaders at once, it has to be, else we'd be extinct.

      Chickenpox is not a harmless virus – not only does it kill children every year, it leads to the debilitating illness Shingles as adults. Shingles in some people can lead to lifelong miserable pain that is difficult to treat – it is definitely worth preventing. HPV causes genital warts and cervical cancer – there are still thousands of women who die from this every year. I think it is ridiculous that you think these illnesses are harmless. Vaccines save lives and prevent suffering. I know elderly people with polio that have lived lifetimes of disability and I am sure they would have preferred to have been vaccinated rather than life that life of disability.

      One of the posts above notes a few kids die from chicken pox and that adults might get bells palsy if the get the disease. Others claims that a child is asssulated with more antigens if they get a cold. Each misses the point. There is no precendence in nature to the kinds of multiple simultaneous exposures in combination vaccines admisitered at the same time as other vaccines. We are messing with things we don't understand and seem not to want to study. There is no doubt in my mind that we are taking a risk. Vaccines are important, but we should be far more careful with how we vaccinate, when we vaccinate and what we vaccinate against. And, to JK Boon above who said "Several children die each year from chicken pox. I bet ALL of their mommy's wish they only had autism," I say try living the life of my son who is non-verbal and impaired in a host of ways. I would have rolled the dice on a chicken pox infection and shingles over his difficult and dependant life. The zealots who refuse to eveen inquire into the possibility that the combination of vaccines contributes to autism are the rue members of the flat eartch societ. Shame on them.

    This is a non-story. Nearly anyone with a decent education knows that the elation between the chemicals in our environment and an increase in birth defects is well established. The truth is that chemicals are virtually everywhere, and have become so much a part of our modern society that, like fossil fuels, they are nearly impossible to limit or replace. There is a price to be paid for a modern technological society, and autism is one form of payment. There are many others. You want to know why the toxic substances act hasn't been updated, why it is virtually impossible to get the FDA or EPA to commit to any useful program of review or regulation? Those agencies are designed to work WITH corporate America, not against it, and that is by political consent. Whose going to change things, Congress? Seriously, do you realize where the bulk of the money comes for election campaigns? Your representatives are bought and sold like any other commodity. They then muddy the waters, hold hearings without conclusions, challenge evidence or bury it, delay, and generally do exactly what they are being paid to do by the companies to which they owe their position. All this in the name of large short term profits, so that those of you out there who own stock in chemical (and virtually every other industry) companies can obtain as large a quarterly dividend as possible. I guess we'll worry about the future when it gets here, right?

    The autism-vaccine link persists because there are hundreds of parents with a painfully similar story: they had a perfectly normal, happy one or two year old who they brought in for their regular round of vaccines and the child had a horrific reaction and then began disappearing into autism, losing language, losing eye contact, etc. Is it just a coincidence of timing, for all of them? As a parent, it is terrifying. And, actually, mercury has not been removed from all vaccines given to children - as a parent, you have to ask and demand to make sure you get only the vaccines without thirmerosol. This includes the flu shot. And even if they don't have any mercury, vaccines contain other chemical preservatives, such as aluminum. Has anyone studied the effect of injecting infants with high doses of aluminum? Also, I wonder if anyone has studied the effect of the sheer volume of vaccines on developing brains and immune systems? Any one vaccine, by itself, may be just fine, but kids today get so many at one time. A two month old baby might get 4 shots at one visit, containing 6 different virus/bacteria vaccines. That is alot for someone who weighs maybe 10-12 pounds. And they keep adding new ones.

      I agree with Kay. Our grandchild is autistic and showed signs of autism after getting the shots. Prior to getting the shots he was advancing very well for his age. I agree vaccines are needed but too much at one time is not working for all kids. If vaccines are determined to be the cause – lawsuits will be huge and parents will not immunize their children for the necessary shots. Something has to be done.

      Have you ever heard the Latin phrase:

      post hoc ergo propter hoc

      It means, literally, after which, therefore because of.

      That means that if something happens after an event, that event is the cause of what happened.

      If it rains in the morning, and your dog gets sick in the afternoon, then obviously the rain caused your dog's illness. This logical fallacy is at the heart of the anti-vaccinators arguments. As you can see from the example, it's a riduculous conclusion to draw. One might well point at the breakfast cereal they had the day of their vaccinations and say that the cereal is at fault.

While yes, Autism could be caused from our toxic environment's effect on and through the mother or father, there are literally millions of reasons this could happen to a developing fetus in the womb, that should be examined. A thought would be instead of fighting over the cause, see it for what it actually is and find the cause to make it stop; just a thought...

    As a clinical instructor in Speech Pathology at the Univ.

The main difference in the past 35 years has also been the spike in environmental and food related toxins. The only control women of child bearing age have is to reduce where possible any toxic chemicals in clothing, furniture, food, toys, home remodel materials, household products, electronic products and on and on. Toxins are pervasive- but for an environment with an infant or a pregnant women, one needs to be very conscious- For example most foods with high-fructose corn syrup (in most processed foods) is processed with a mercury based solution.

      My daughter had an autoimmune reaction to strep throat, similar to rheumatic fever (it's called PANDAS). Her immune system began attacking the basal ganglia of her brain. That's "brain damage". Left untreated, it could have been progressive and irreversable. It had nothing to do with a vaccine, but it's not outrageous to think that some children through a combination of genetics and possibly even chemical exposure or even nutrient deficiencies are more susceptible to these types of autoimmune reactions and that their immune system's faulty switch might be "tripped" by vaccination.
      That said, I still choose to vaccinate my children because I feel it is irresponsible not to. The diseases these vaccines prevent are deadly. Death, die, dead. Look at it similar to penicillin - my youngest child is allergic to penicillin. Should penicillin be shunned because some people are allergic to it? Of course not. I firmly believe that the researchers will eventually piece together a better picture of how autism comes about, and better treatments and therapies. But there's no sense in potentially exposing your child to a disease that could kill them out of fear of autism. The science and the odds are not on that side.

    A friend with an autistic son found out that he is much better without wheat or food colorings and artificial flavors. There are a number of genetically engineered foods (not labeled) including wheat, corn syrup (which is not made by a natural process), etc. If two family members are suddenly allergic to a vegetable, and it turns out that it is genetically engineered, that may cause problems. (My daughter and I go into shock now from lima beans). Anything that the intestines have trouble with can affect the brain: before birth the skin, stomach, and brain are connected, and anybody with motion sickness knows that the eyes rule the stomach; new studies link melanoma and Parkinson's disease. There should also be more investigation of makeup worn by pregnant women.

    The cause of Autism and other neurological disorders will be found to be demylination or non mylination of the fetus/childs brain. Various chemicals in insecticides and herbicides are known to cause demylination. The myelin is the covering over the nerves that helps transmit signals. Either certain protein production or the destruction of the protein (MBP) might simply have varying effects depending upon the timing. This is why at the time of the MMR so many children appear to become autistic. Myelion production continues until age 18 when the brain is somewhat complete. Girls have more myelien than boys. Their corpus callosum is larger so they can afford to lose more and still function ok. Girls get more MS, another deyminating disease. Boys get more autism and ADHD.
    Next time you meet someone with MS, ask them if they ever spent any time near a golf course during puberty.

    Also, high tension wires that were fro decades thought to cause childhood leukemia?? HOGWASH. Herbcides used by the utility company similar to agent orange as defoliants were the cause.

    Its a big CONSPIRACY by MONSANTO, DOW, CHEMLAWN, SCOTSS. They will kill the human genome within 3 generations.

In this article, I believe I read (several times) about the chemicals that "interrupt normal hormone" processes. I would think that nothing interrupts the normal hormonal process more than birth control pills. It is likely more women are on birth control pills today than ever before. Maybe that's why the autism rates have risen so much. Or...maybe back in the day, people weren't so quick to run to doctors to diagnose everything as a medical problem.

      If you have or have ever seen a child with autism, you would not think of it as something parents just complain about, so we have more of them diagnosed. This is a matter of national health emergency, but it is not treated with the urgency it deserves. Naturally, for a country in which it is AGAINST THE LAW to label products that use genetically engineered products, irradiation, or even chemicals used in processing the food prior to its final phase, what do you expect? Serious discussion of the problem would require that we have all the facts. Survival will depend on not trusting anything one eats, or uses around the house.

    Duh! I've been saying it for quite some time! Chemicals that are in the food chain are probably the most contributing factor to autism. I personally think it's in the fertilizers. With the advent and usage of more and more chemical fertilizers, as opposed to those found more readily in nature, we have seen a steady rise in autism cases. I think there's another factor that cause the links to connect, but I'm not sure what it is. If it were strictly one thing, then everyone would be autistic, so I would think a catalyst must be interactive somewhere. It's just my point of view.

    I sincerely hope that a therapy, whether gene, behavioral, medicinal or whatever, is found to help all those who are afflicted with autism. Best wishes to all.

    Autism and autism spectrum of disorders run in my family. It's wiring – frontal lobe wiring. Nothing CAUSES it. It is natural. Temple Grandin's books are revealing and highlight her both genius and perseverance which both made social obstacles for her. Everyone is so busy looking for a cause, perhaps they aren't looking in the right places. There is real evidence for an evolutionary step here. Grandin makes the point that the different between humans and other animals is frontal lobe wiring. She posits that the difference between autistics and so-called "normal" human beings is frontal lobe wiring. I find that quite a comforting thought in that the "normals" haven't done a heck of a lot of good in their tenure on the planet except create righteous war. Perhaps the sensitivities innate in the rest of the animal kingdom, if humans evolved in the frontal lobe, would make a constructive change in human arrogance. Sensitivity is a good thing, for compassion, for creativity and for survival.

      You could argue that genetic mutations are also normal. There are many cases of families with no history of autism, and then suddenly they have a child with autism.

      I've read two different studies (2009 and 2011) that allude to genetic mutation, and markers for autism not being present in either parents.

    Autism could also be related to natural evolution of the human species. Think about it, you get two extremely smart people, who have difficulty socializing find it hard to work with people, and then they mate. What is the by product? A child who is developmentally behind in social and communication milestones.

    Look up Dr. Simon Baron-Cohen and his numerous studies on Autism.

      I know it's just anecdotal, but I have two good friends that meet the description of your hypothetical parents and the eldest product of their union confounded his educators to the point that they asked that he be evaluated for autistic spectrum disorder. Guess what, he's just wicked smart and processes things emotionally just fine, but faster and deeper than his peers. Their lives would have been needlessly turned upside down if an inexperienced therapist did the evaluation. What concerns me is the rush to label. I fear that being socially awkward could be enough in some cases to earn the brand autistic and that taxes the resources for those that truly need help.

    "Not vaccine related" though there are all sorts of neurotoxins in vaccines including mercury, formaldehyde, alcholol, etc.??? THOSE chemicals (many the same that you quoted in your article) couldn't contribute in addition to others? I find that difficult to believe - especially as a mother of a child with autism who saw the symptoms manifest OVERNIGHT after receiving 7 immunizations in one doctor visit.

    I ought to put up a glyph of annoyance.

    Autism is almost certainly genetic. NUMEROUS studies have shown this over and over again.

    Multiple studies have shown that autism is a lot less tied to the environment than it is to mother's age.

    UC Davis study confirms link between advanced maternal age and autism:

    Link to autism in boys found in missing DNA:


    This looks very much like a case of X chromosome replication error during Oogenesis (look it up on wikipedia). These increase as a woman gets older. With the fact that more and more people are postponing their fertility, this is HIGHLY likely to increase. And, gosh, that's exactly what it has done.

    There was another study that looked for an environmental cause for autism (which I cannot find the link for now). it sampled the poor, rich, etc across California. The highest demographic concentration of autism? White, wealthy families in Marin/Napa (if I recall correctly). Precisely those that postpone their fertility.

    That postponed fertility could be the cause shouldn't surprise people. There is ample evidence that the incidence of Down's Syndrome greatly increases as a mother passes the age of 35. Why couldn't there be others?

    While I am all for cleaning out the environment of those chemicals that everyone is ranting about here – they are bad for multiple reasons even if they have zilch to do with autism – we have to realize that our choices can effect our children, too. This is increasingly looking like our fertility choices, too.

    PS: Yes, autism can strike the children of younger mothers, just like Down's can. Nature is messy and oogenesis can go south even with young women. However, the incidence is far, far less.

      A link to genetics? Almost certainly. Implying that it is 100% genetic? Almost certainly not.

      From your second study, those missing the PTCHD1 gene were "at higher risk" for developing autism. Just how much higher is not stated in this summary.

      Also A implies B does not mean B implies A. In other words, the problem is that there are many, many people with autism who DO have the PTCHD1 gene. So while intriguing, the study is not a complete answer.

      @TheBear: It's probably not caused just by /that/ gene being defective. Genetics is a lot more complicated than just a on-off signs in most cases. However, if I recall correctly, with a ratio of something like 4:1 or 5:1 bias for incidence in boys over girls should have been a red flag from the beginning. That alone screams X linked "trait."

      There is unqeustionaly a link and an X-linked recessive gene clearly plays a part.

      But we know that it is not 100% genetic. If it were, then if one identical twin had autism then the other twin MUST have autism. No study has every found this to be the case. In this particular study I quote, the rate was 60% :

    What has been generally accepted is that there is no one "cause" of autism. In fact, it's probably safe to say that "autism" is not one condition, it is merely an umbrella term to describe a host of difficulties in behaviour, communication and socialization. Much the same as "fever" is not a disease but merely a symptom.

    This makes research incredibly hard, because 25 children with autism might have 25 different conditions, each with its own unique combination of genetic and environmental factors that triggered the symptoms.

    We must first understand the human brain better. The interactions that go into shaping our brains when we are very young are so complex that we simply don't understand enough about them at this point in time.

      100% dead on Dr. N. Toxins, such as chemicals described in this article, must be removed from the body via detoxifying process carried out by by enzymes created by the liver. The body is taxed by this need for constant detoxification, which takes enormous amounts of trace elements (e.g. Molybdenum for sulfites) and nutrients to maintain. Ultimately, this process leads to nutritional/enzyme creation depletion and increase in chemical sensitivities/intolerances. Unless you suffer from this breakdown, it would be easy to dismiss adverse affects on the body. If none of this is true, why the increase in cancer rates – a disease strongly linked to free-radicals, which are created during the detoxification process?

She was so freaked out that she found black ants in her yard. Also a man I worked with that had 3 children, sprayed his lawn with such caustic chemicals that he burned out the inside of him mouth and nostrils. Yes of course his children are going to play in that yard. I encourage people at every turn to use organic pesticides and more importantly get over having bugs in your environment. Big deal!

      Umm... Roundup actually reduces the use of other weed control agents to a very high degree. Other GM crops have reduced dependence on pesticides. Other GM crops have cut down on the amount of fertilizer needed. Getting rid of things like Roundup Ready and other GM crops would actually lead to an *increase* in the amount of chemicals used to grow food. Of course, you can move the entire food supply to organic production but we'd end up with significantly higher prices on food due to the reduce crop yield.

    Of course it's chemicals in the environment. That really is not a new idea. The problem is that it is probably not any one chemical but the aggregate load on the developing brain. It is also clear that autism is just a label for a severe form of a brain development disorder. The causes may be different in any individual, which is why the comment about children raised away from urban environments with very little overall exposure need to be studied.

      Define "away from urban environment." There was a recent study in Los Angeles to determine the spread of aerosol pollutants in the vicinity by using special chemical markers in their aersol products. They found that pollutants from as far south as Anaheim and Huntington Beach made their way as far north as Beverly Hills and Malibu– a distance of around 40 miles. Since most of the United States lives in urban and suburban areas, it's more than likely you live within 40 miles of something you don't want to breathe in.

      That's the issue though. Suburban environments require more energy, more fuel consumption and the fact that they are so large also means there's little one can do to isolate and confine pollution sources. And urbanity maybe have little to do with pollution— the West Village and the Financial District has the two of lowest and highest levels of air pollution in U.S. cities and often these low-high differences are separated by mere blocks. Also, one thing to point out is that the air pollution levels in Manhattan fluctuate wildly even during the day with the night having almost no air pollution while during rush hour having the highest levels.

      So, even if you live out in the country but spend a fair amount of time commuting, you're probably inhaling more polluted air than a city-dweller with an irregular schedule.

      Um NO, Thimerosal, you know, the ethyl-mercury containing preservative that was used in vaccines, was for the most part not used anymore after 2001. So if the ethyl-mercury that was used in the preservative, which by the way is a different type of compound than the type of mercury used in fillings, was not used commonly after 2001, why did autism diagnoses not drop after 2001? Ummm...you guessed it, the ethly-mercury was not causing the autism.

      Get your facts straight buddy. They removed thimerosal from childhood vaccines in 2004. Those that were produced were still on the shelves far after that. Until about 2006. If your kid gets a Flu shot, it is often the "adult" version which contains thimerosal to this day. While they don't have mercury anymore a lot of kids still get vaccines that do contain mercury(flu shots). By the way, mercury from both fillings and vaccines crosses the BBB and doesn't come out. Ever. Unless you take a chelating agent with two thiol groups(Alpha Lipoic Acid). So the autism rate wouldn't expect to fall until around now. Those who were the last to receive a lot of thimerosal in their vaccines were a few years past 2004.

    I think it's largely the fact that a lot more people are being diagnosed with it, more so than an increase in the actual number of people who fall on the autistic spectrum. Additionally, we have more tools available today for meeting potential mates so it's more common for people who are socially awkward to have some success at finding mates. There are several cases of Aspergers in my family, all in men and most of us are engineers. I would hazard to guess that a large majority of engineers and scientists out there have some autistic characteristics. Aspergers syndrome pretty much describes the stereotypical nerd, we just have a fancy clinical name for it now.

    I am not an expert or scientist in any way, but I remember my daughter (now 3) being vaccinated all the time for the first 2 years or so of her life. It seemed like she didn't go three months without some sort of vaccine. So if she had shown signs of autism at any point during her first 2 years, it would have been very easy to say "wow, she just had that vaccine."

    I can't say with 100% certainty that vaccines don't have a link to autism (can anyone be 100% sure), but it is going to take a lot more than the current theories to get me thinking about skipping vaccines for my next child. The risks of not vaccinating are concrete – so I choose to avoid those.
