Did anyone else hear of the recent Harvard study linking air pollution exposure during pregnancy to autism rates? I just heard about it on the radio, and don't have time to post a link right now. But it sounds fascinating. Although it probably won't apply to me or my son with autism (we lived on a fairly remote island in the Puget Sound during my pregnancy with him - few cars, and NO trucks or trains), the idea makes sense to me to explain the skyrocketing rates we are seeing.

After doing a ton of research on this I'm convinced that the massive increase in ASD rates are caused by a combination of increased reporting, coupled with a genuine rise caused by environmental factors that are triggering genetic tendencies.  So yeah, I'd totally buy that pollution, exposure to toxins, etc will all eventually be proven to play a role in rising ASD rates.

Anything but vaccines.

 

The germline

 

Quote:

The decades of the 1950s, 60s, and 70s were the heyday of prenatal pharmaceutical use.  Countless millions of us were exposed in utero to synthetic hormones, tranquilizers, amphetamines, morning sickness medications, and/or other drugs prescribed almost indiscriminately in a haze of unbridledenthusiasm for the promise of the new pharmacopeia. Until the 1970s, little thought was given to these potent chemicals' impacts on the fetus, as doctors falsely considered the placenta a fairly impenetrable barrier to the mother's medication. As we grew up, we were seldom told of our exposures, little follow-up research was done, maternal memories faded, and old medical records were thrown away.

 

 

Autism The (Enviromental Induced) Genetic Epidemic

 

 

Quote:
Opening presentation at Environmental Epigenetics: New Frontiers in Autism Research symposium at UC Davis MIND Institute, March 22, 2013. Here, Jill Escher, a science philanthropist and mother of two children with autism, posits that past exposures, particularly widespread prenatal exposures to popular mid-20th century prenatal pharmaceutical drugs, such as synthetic steroid hormones and sedatives, have impacted vulnerable fetal germline epigenetics, resulting in a surge of developmental abnormalities in the grandchild generation. This is now known as the Germline Disruption Hypothesis of autism.

Oh, my. I just checked out these links. This is the most terrifying, yet sensible, explanation I have ever heard for autism. I also found a mention of PCOS (policystic ovarian syndrome) which my daughter has. I was conceived in the 50's, and wonder what sort of medical treatments my mom received. She is 95 years old, and has near 100% mental facilities. But I don't know how I could ask her without "blaming" her for DS's autism, of DD's PCOS. I don't mean I would blame her, but she would definitely take on the guilt. I will need to talk with her very gently about this. She grew up in a coal mining town in West Virginia. It is hard to imagine what toxins her mother was exposed to. I am a total nerd on the subjects of microbiology, genetics, evolution, and epidemiology. While I am familiar with the term epigenetics, this is the first time I see such a direct connection to my family and our situation. None of the explanations I have ever heard for autism (diet, vaccines, direct environmental factors, etc). seem to apply to us. I am looking forward to a major upswing in my personal research time. This is fascinating to me! Oh, my.

Well, I know for a fact my mom was on synthetic hormone for almost the entire back half of her pregnancy with me... nausea meds the first half. It does make a lit of sense.

I'm a firm believer that autism is genetic and exterior things may have greater affects on Autistic children, but don't cause it. I think Autistic individuals are more sensitive to environmental toxins and as a result may display more "autistic traits" as the body fights these toxins, but I feel it was there all along. This may be why some children benefit from special diets and such but not all see improvement, same with vaccinations and other similar outside stimulus. This is all just a personal hunch/idea though based on my own experience (as a mom of two autistic children, being on the spectrum myself and working with special needs children), I wouldn't be surprised in years from now someone does a study on this theory (I can hope at least!).
