Toxic chemicals: a serious suspect in the autism outbreak

Great article. Depressing as heck though.

I just excerpted a tiny bit for you in my post. Please read the whole thing. In fact, read all of Harvey Karp's articles on Autism here.

From the Huffingtonpost.com:

Are Children with Autism..."Male-adjusted"?

Our increasing exposure to EDCs lends support to a new hypothesis about the cause of autism, called the "extreme male theory." This theory, proposed by Dr. Simon Baron-Cohen and colleagues, speculates that autism is caused by something changing a fetus' hormonal balance that then leads to over-masculinization of the developing brain.

Could that "something" be the slurry of hormone-altering chemicals we're exposed to every day? Are EDCs the reason autism-type disorders are 4-9 times more common in boys? (Vaccine side effects never show such lopsided impact on boys versus girls...a glaring fact that is totally ignored by those promoting the vaccine theory of autism.)

The "extreme male theory" has been supported by two interesting bits of evidence: 1) fetuses with slightly elevated levels of testosterone grow up acting extra-male (more interested in things than people, slow language development, etc.); 2) children with autism -- boys and girls -- show extra-male characteristics (e.g. poor social ability, language delay).

Here is where the very interesting link to EDCs comes into play: EDCs often act as weak estrogens and estrogen feminizines the body, but in a fetus' developing brain estrogen actually has the opposite effect...it causes masculinization.

For now, these ideas are just interesting theories, but the evidence is concerning. We urgently need more research to discover whether EDCs, or other chemicals, are linked to the worldwide rise in autism. Fortunately, on that front, there is very good news to report. Thanks to a dedicated group of pediatricians -- members of groups like the AAP and CDC -- the National Children's Study (NCS) was launched in January 2009.

Prenatal Ultrasound and the alarming increase in Autism

Hat tip to a blog I regularly read, If I were in your shoes..., who made this link available a few days back.

I just couldn't stop thinking about it.

Could the increase in Autism have something to do with the mainstreaming and increase of Prenatal Ultrasound use?

Interesting article.

From Midwifery Today:

In May 2006, figures from the Centers for Disease Control (CDC) confirmed what too many parents and educators already knew: The incidence of autism is high, making it an "urgent public health issue," according to Dr. Jose Cordero, director of the CDC's National Center on Birth Defects and Developmental Disabilities. Only 12 years ago autism spectrum disorder (ASD) was so rare that it occurred in just one in 10,000 births.(1) Today ASD, which is characterized by a range of learning and social impairments, now occurs in one in 166 children (2)—with no sign of leveling off.

The steep increase in autism goes beyond the US: It is a global phenomenon, occurring in industrialized nations around the world. In the UK, teachers report one in 86 primary school children has special needs related to ASD.(3)

The cause of autism has been pinned on everything from "emotionally remote" mothers (since discredited) to vaccines, genetics, immunological disorders, environmental toxins and maternal infections. Today most researchers theorize that autism is caused by a complex interplay of genetics and environmental triggers. A far simpler possibility worthy of investigation is the pervasive use of prenatal ultrasound, which can cause potentially dangerous thermal effects.

Health practitioners involved in prenatal care have reason to be concerned about the use of ultrasound. Although proponents point out that ultrasound has been used in obstetrics for 50 years and early studies indicated it was safe for both mother and child, enough research has implicated it in neurodevelopmental disorders to warrant serious attention.

At a 1982 World Health Organization (WHO) meeting sponsored by the International Radiation Protection Association (IRPA) and other organizations, an international group of experts reported that "[t]here are several frequently quoted studies that claim to show that exposure to ultrasound in utero does not cause any significant abnormalities in the offspring. …However, these studies can be criticized on several grounds, including the lack of a control population and/or inadequate sample size, and exposure after the period of major organogenesis; this invalidates their conclusions…."(4)

Early studies showed that subtle effects of neurological damage linked to ultrasound were implicated by an increased incidence in left-handedness in boys (a marker for brain problems when not hereditary) and speech delays.(5) Then in August 2006, Pasko Rakic, chair of Yale School of Medicine's Department of Neurobiology, announced the results of a study in which pregnant mice underwent various durations of ultrasound.(6) The brains of the offspring showed damage consistent with that found in the brains of people with autism. The research, funded by the National Institute of Neurological Disorders and Stroke, also implicated ultrasound in neurodevelopmental problems in children, such as dyslexia, epilepsy, mental retardation and schizophrenia, and showed that damage to brain cells increased with longer exposures.(7)

Dr. Rakic's study, which expanded on prior research with similar results in 2004 (8), is just one of many animal experiments and human studies conducted over the years indicating that prenatal ultrasound can be harmful to babies. While some questions remain unanswered, based on available information, health practitioners must seriously consider the possible consequences of both routine and diagnostic use of ultrasound, as well as electronic fetal heart monitors, which may be neither non-invasive nor safe. If pregnant women knew all the facts, would they choose to expose their unborn children to a technology that—despite its increasingly entrenched position in modern obstetrics—has little or no proven benefit?

Italian study: no connection between Autism and Thimerosal

I know there are many studies out there that seem to prove that vaccines or the mercury preservative "Thimerosal" does not cause Autism. But, I also know there is a literal ton of anecdotal evidence from real life moms and dads who noticed something change in their kids after a routine vaccine.

I am reserving judgment and my opinion for now. But, I would like to see more money and focus on treatment, support and therapies. Plus, if they really don't think it was the vaccines...WHAT THE HELL CAUSES IT THEN!!!!

1 out of every 150 babies is way too many.

From AP/The Seattle P-I:

A new study from Italy adds to a mountain of evidence that a mercury-based preservative once used in many vaccines doesn't hurt children, offering more reassurance to parents.

In the early 1990s, thousands of healthy Italian babies in a study of whooping cough vaccines got two different amounts of the preservative thimerosal from all their routine shots. Ten years later, 1,403 of those children took a battery of brain function tests. Researchers found small differences in only two of 24 measurements and those "might be attributable to chance," they wrote in the February issue of the journal Pediatrics, which was released Monday.

Autism could be connected to the rain?

Very interesting article in the Seattle PI this morning, "Study looks at autism, rain"

Check out the full article if you have the time. This is not, of course, definitive or proof of anything but I thought it was pretty darn interesting.

Here is an excerpt:

Cornell University researchers said children living in rainy counties appeared to have higher reported rates of autism than those in drier areas, after analyzing data from Washington, Oregon and California.

Washington counties west of the Cascades, for example, got four times as much precipitation and had autism rates twice as high as those in the East, according to the study's co-author, Sean Nicholson.

In rain-soaked Seattle, some parents saw these findings as yet another piece in a complicated puzzle. There is no known cause of autism and no established cure.

"I kind of think there is something to the kids not getting enough vitamin D," said LeAnne Beardsley, whose 4-year-old daughter, Keely-Fae, has been diagnosed with autism. "This study really doesn't surprise me at all."

Wow! So does this justify a trip from my beloved Pacific Northwest to a sunny clime during the winter?
