The Age of Autism: Mercury and the Amish

By Dan Olmsted

WASHINGTON, May 20 (UPI) -- The cases of autism among the Amish that I've

identified over the past several weeks appear to have at least one link -- a

link made of mercury.

That's not something I expected to encounter. I had been looking for an

unvaccinated population to test the controversial idea that vaccines, and in

particular the mercury-based preservative called thimerosal, could be behind the

apparent rise in autism cases over the past decade.

The concept: If the Amish have little or no autism, it might point a finger at

something to which they have not been exposed.

Most of the medical establishment, it must be stated upfront, considers the idea

that thimerosal could have played a role in the rise of autism disproven and

dangerous. As noted in the last column, however, the director of the Centers for

Disease Control and Prevention says she has " an open mind " about that

possibility.

So do I, having come across correlations that made me want to look more closely

at thimerosal. For instance, the first child diagnosed with autism in the United

States was born in 1931, the same year thimerosal was first used in a vaccine.

And autism diagnoses exploded in the 1990s, the same decade children got an

increasing number of thimerosal-containing vaccines (it was phased out starting

in 1999). Tantalizing, but proof of nothing.

So I turned to the 22,000 Amish in Lancaster County, Pa. I didn't expect to find

many, if any, vaccinated Amish: they have a religious exemption from the

otherwise mandatory U.S. vaccination schedule. When German measles broke out

among Amish in Pennsylvania in 1991, the CDC reported that just one of 51

pregnant women they studied had ever been vaccinated against it.

To cut to the chase, what I've found to date is very little evidence of autism

among the Amish in Lancaster County, far below the 1 in 166 rate of Autism

Spectrum Disorders the CDC cites for children born in the United States today. I

don't discount the idea that they might be more difficult to find or diagnose,

and I'm still looking.

I did find three or possibly four children with autism and, weirdly, a possible

link to vaccinations. One was a child adopted from China, where she got all her

vaccinations before being vaccinated all over again when she got to the states.

Her Amish-Mennonite mother said she believes that vaccine load caused her

autism. The mother told me about another child who had what she described as an

immediate vaccine reaction that left her autistic at age 15 months.

That mother said a minority of younger Amish have begun getting their children

vaccinated, though a local doctor who has treated thousands of Amish said the

rate is still less than 1 percent.

The pattern I was noticing then took an interesting twist. From a doctor's

posting on an alternative health Web site, I learned about several cases of

autism among Amish children who had not, in fact, been vaccinated.

I called that doctor, Lawrence Leichtman, at his office in Virginia Beach, Va. A

pediatrician and geneticist who has been widely published in medical journals,

he told me he was treating six unvaccinated Amish children and adolescents --

three from Pennsylvania, including one from Lancaster County; two from Ohio, and

one from Texas.

That seemed to render any relationship between autism and mercury exposure in

the Amish less likely. But, not after what Leichtman said next.

" By the way, " he volunteered, " four of these six kids all have elevated mercury.

The only two that don't, one of them is from Texas and one is from Iowa. But all

of the people in Pennsylvania and one of the people in Iowa have elevated

mercury. "

Given what I had already come across in Lancaster County, I wanted to hear more

about that. Were the mercury levels significantly higher? I asked. " Oh yes, " he

responded.

What did he think was going on?

" The people in Pennsylvania, I've actually tracked back on them, " Leichtman

said. " There's definitely a plume from one of the coal-fired power plants that

just goes right over them. And the one in Iowa, it's a little less obvious

because actually he's in the Amana Colonies, but I have seen reports of the area

around Amana having elevated levels of mercury in the environment. "

As it happens, the Pittsburgh Post reported last week that Pennsylvania has four

of the nation's 10 " dirtiest power plants. " Mercury is a byproduct of coal

combustion.

Leichtman also believes that northern states " get most of the prevailing wind

that comes across the Pacific. You get that trans-Pacific flow which is all

Chinese mercury. We're getting a load of Chinese mercury, as far as I can tell. "

Leichtman's comments meant that the two people I talked to, who knew anything

about autism among the Amish, independently brought up mercury exposure -- in

vaccines and in the environment-- as the cause of most of the cases.

That's a link others have made, although not to the Amish, whose autism

prevalence has apparently never been studied:

- " We believe that thimerosal and environmental mercury -- which are worldwide

pollutants -- are behind the surge " in autism in the 1990s, wrote Sallie Bernard

in 2002. She is a founder of the group Safe Minds, which wants mercury out of

all medical products. Bernard co-authored a controversial 1999 study about

thimerosal, " Autism: A novel form of mercury poisoning. "

- " In the end it is mercury in the brain that causes such problems, and that

mercury can come from several sources, " said Boyd Haley, chairman of the

chemistry department at the University of Kentucky and another maverick on

thimerosal.

" Therefore, a logical approach is to think that all mercury exposures are

additive, even if some may be more causative than others. "

Haley cited a recent Texas study, first reported by United Press International

in March, that found an association between autism rates and exposure to

industrial mercury emissions in Texas counties. One county with high autism but

low exposure to mercury emissions turned out on closer inspection to be the site

of a huge abandoned mercury mine, the researchers found.

Leichtman believes the damage to children is being done by environmental

mercury, not the mercury in vaccines (my own research makes me think that if

it's either, it's both). He said he can detect elevated mercury levels in about

half his 500 autism patients.

" Environmental mercury is horrible, " he said, " and I think that's where it's

coming from. To me, people with autism are the canaries in the coal mine. A lot

of them are reflecting the damage from all of that. "

Leichtman, like a number of other doctors, is trying to flush mercury out of

autistic children through a process called chelation (key-LAY-shun).

Chelation as a treatment for autism is unproven and controversial (what about

autism is not unproven and controversial?), and it carries a risk of serious

side effects. Chelation has been used for 40 years in cases of heavy metal

toxicity, including lead poisoning.

But does it help children with autism?

" The people in Pennsylvania wouldn't take chelation, " Leichtman said, and noted

the Amish aversion to medical procedures and drugs. " One in Iowa did. He

certainly did better. "

We'll look at chelation and its implications in the next column.
