Powerful Autism public service announcement

16 Apr

Autism Steals….

Autism leaves an empty shell…

These are autism myths. This public service announcement is a good video to show people to address these (and other) myths–it is professionally done and carries a simple yet powerful message.

ASAN worked with the Dan Marino Foundation and Kent Creative to develop the PSA.

Leave the old stereotypes behind.

Very well said.

[edit]
Ari Ne’eman is correct–there is a national discussion on autism, and it is happening without the autistics. That is wrong.

Here is the captioned version (thanks codeman38!)

Omnibus Expert: Patricia Rodier

10 Apr

Autism just plain isn’t mercury poisoning. When can we move on?

Even some of the people who loudly promoted the mistaken idea that “autism is just a misdiagnosis for mercury poisoning” have backed off. But, the groups that promote autism as vaccine injury are packrats: once they’ve collected an idea, bad or not, they won’t ever let it completely go.

Some of you will be thinking, dang, another mercury post. I agree, there are a lot of good arguments against blogging about the mercury-autism connection any more. For one, it gives the idea press that it just doesn’t deserve.

I do think this is worth posting about, though. “This” is the expert report from Dr. Patricia Rodier, submitted to the Autism Omnibus Proceeding. In a single document, we now have an expert on both mercury toxicology and autism. Not faux experts, or worse, businesspeople and public relations people, but an actual, bone fide expert in both fields. I.e. we have a good document to give to people who are being snowed under by the misinformation campaign promoting autism as mercury poisoning.

When Patricia Rodier testified in the Autism Omnibus Proceeding, I was very impressed–and I blogged it right away. I remember at the time telling a friend that it was good to finally see someone officially debunking things like Sally Bernard et al.’s paper, Autism: a novel form of mercury poisoning. My friend pointed out that any college freshman in science (and most not in science) should be able to tear that “paper” apart.

Unfortunately, “should be able to tear the paper apart” isn’t enough. Many people don’t have the time and/or energy. So, many people still think that paper is valid. Let’s face it, that “paper” should have been retracted by the authors long ago, but they still soldier on with the “autism is mercury poisoning” message.

Dr. Rodier’s qualifications are quite good. Her summary is quite good:

As a research scientist who has studied both the toxic effects of methylmercury in animals and autism in children and animal models, I believe I am qualified to evaluate the scientific merit of the allegation.

She may be the only person in the world who has studied both mercury toxicity and autism.

What does she think? In a nutshell:

My conclusion is that the allegation has no scientific support and is highly improbable

Dr. Rodier notes that the comparison that autism and mercury poisoning appear similar isn’t even close.

In othcr words, because the symptoms of methylmercury poisoning
are not similar to those of autism, the authors have tried to construct a new, hypothetical kind of mercury poisoning from symptoms of toxicity of other mercury species and symptoms never reported for any kind of mercury exposure. The hypothesis is not based of facts; instead, the facts are being selected, manipulated, and shaped to fit the hypothesis. The hypothesis is then offered as evidence. But hypotheses are not evidence.

Ouch. Ouch, that is, if you are someone promoting autism-as-mercury-posinong.

Dr. Rodier can back up her words, as we discussed in the previous blog post. But, let’s say that again, Dr. Rodier uses research based facts, not manipulated hypotheses, to come to her conclusion.

I need to get a clean copy of that document, one that looks as good as the information it contains. That document needs to get into the hands of people being lured by the pseudo scientists promoting autism as mercury poisoning.

Thank you, Dr. Rodier for putting yourself on the line to testify. Thanks also to the HHS for allowing these reports to be made public.

Lies, Damned Lies and Science

7 Apr

Prior to starting a family I was already a skeptic and a subscriber to Skeptical Inquirer. This means I looked twice at the “helpful” information I got from all sides. From whether or not my baby would be a boy or a girl, what might have caused his seizures (like that fact that I drank milk, which was offered as an explanation after the “helpful” person was told he was infant only on breastmilk), the assurances I got that he would talk “when he was ready” or that someone’s cousin four times removed or Einstein did not talk until age three, five, or thirty-five (by the way, the Einstein is a total myth, don’t believe it — and don’t accept your child being compared to Einstein, he really had several flaws! See Private Lives of Albert Einstein, I should mention that sitting in therapy waiting rooms does provide lots of reading opportunities), and most recently I was told to try cranial sacral therapy (like a light head massage is going to “fix” the pathways in the brain that make him different!).

There is a tendency for people to give unsolicited advice to young parents, and that seems to double when it involves a child with a disability. Not only does the amount of advice double, but the relative distance from reality increases exponentially. While a parent of a typically developing child would be told to buy a certain organic baby food or to try some kind of “teach your baby calculus” computer program, the parent of child on a different developmental path would be encouraged to try a myriad of supplements, various odd treatments and to try the “miracle cure” they heard from some famous guy on the news.

How does a parent of a newly diagnosed child wade through the “help”, and determine what is real and what is hype? Well there is help, and it is not a cure all, but a book that shows how to look and science and separate fact from hype: Lies, Damned Lies and Science by Sherry Seethaler, a science writer and education at the University of California in San Diego..

It is not a long book, and is separated into short chunks to help explain the basics of science, why disputes in science is not really a bad thing, how to interpret numbers, and who the stakeholders on an issue are, and why they are important. She includes many real world examples and even comparisons to situations in the Harry Potter book where he excels at potion making by using the notes in the margins of an old book.

In Chapter 7, “Fun Figures”, there is a subsection titled “Ask whether a statistical change reflects reality or the way the data were collected.” Readers of this blog should be very familiar with the example she uses. They will also be familiar with the tactics described in Chapter 9, “All the Tricks in the Trade”, especially the section on pseudo experts.

This is a quick, actually quite a fun book to read. It can be a bit repetitive, but that is in part makes it easier to understand the concepts. I knew much of the information (like statistics), but I still learned a great deal. Check it out of your local library, and even purchase a copy for those friends and relatives who keep giving you all sorts of “advice.”

Autism And Divorce

8 Mar

What is the divorce rate among autism families?

Let’s set aside the fact the this is a very poorly worded question, and let’s just go with the notion that is likely to be pondered by typical peeps on the street – what is the divorce rate among couples who have a child (or children) with some sort of autism spectrum ‘disorder’ diagnosis?

Many bloggers have apparently attempted to look somewhat earnestly at the question – and they often come up empty handed:

Lisa Jo Rudy
“But so far as I can tell, having researched the topic in all the usual places plus a few more (personal connections to reearchers in the autism community), there is no basis for these claims.”

Kristina Chew
“While I have often seen the figure of 80-85% referred to, I have not found a good source for this figure.”

Patricia Robinson
“I can’t find a study that shows that rate.”

But for everyone of those who don’t turn anything up, there appears to be a glut of what looks more and more like internet urban legend similar to the following:

On Oprah
“The stress of raising an autistic child also takes a toll on many marriages. Autism Speaks, the nation’s largest autism advocacy organization, reports that the divorce rate within the autism community is staggering. According to their research, 80 percent of all marriages end.”

I have news for Autism Speaks – 100% of all marriages end, eventually.

In all practicality, there are probably way too many internet discussion forum threads, blog articles, and statements from anti-autism advocacy organizations to really quantify, so I’m not even going to pretend to try. Heck, this is probably one reason this particular urban legend persists – the fallacious logic of appeal to popularity can be strong with the masses.

Let’s just round out that fallacious logic, of truth due to popularity, with a comment from botulinum toxin injection-loving Jenny McCarthy, which is really not much more than ascribing importance to her personal experience (appeal to anecdote).

Soon after Evan’s diagnosis, Jenny says the stress of raising a child with autism began to take a toll on her marriage. An autism advocacy organization reports that the divorce rate within the autism community is staggering. According to its research, 80 percent of all marriages end.

“I believe it, because I lived it,” she says. “I felt very alone in my marriage.”

Source

Well if Jenny believes it, it must be true (and especially so, since she apparently said this on the Oprah show).  😉

Okay, enough already. It’s clear that there is probably a lack of real quantifiable information “out there” about divorce among families with autistic children.

However, Easter Seals (in conjunction with the Austism Society of America) did look at the question (quite recently I might add: July, 2008 – Report Published in December, 2008) as part of a larger “Living With Autism” study. You can download the report (registration required) here.

Even autism super sleuth, Kim Stagliano, over at AoA noted this ‘research’ when it dropped (apparently whining about unsurprising content):

“Click HERE to read more useless information that any parent of an autistic child would have told you for a large coffee and 15 minutes of respite time. Is this what we can expect from the partnership of ASA and Easter Seals?”

Kim obviously couldn’t be bothered with some of the report’s details, really didn’t care, or just skimmed the media story, and didn’t even read the actual report (personally, I’m voting for this possibility as likely). Of course it’s also entirely possible that Stagliano’s absence of mention about the divorce rate information in this survey, is due to lack of interest in the subject, or some other reason altogether.

Pleasantly surprising however, following the AoA post, is a small, yet more astute portion of commentary on AoA (yes, you read that correctly), authored by “Gale”:

It also sheds light on an often misreported urban legend of higher divorce rates for families with autism concluding “Families living with autism are significantly less likely to be divorced than families with children without special needs. Among those parents with children who have Autism Spectrum Disorder and who have been divorced, only one third say their divorce had anything to do with managing the special needs of their children.”

Good on Gale for adding a little to the story here!

So what numbers were actually reported for divorce rates by Easter Seals?

No Special Needs (N=866) 39%
ASD (N=1573) 30%

30% ??? Not only is that 25% lower than the families with no special needs children (the ‘control group’) in this survey, it’s nowhere near the mythical 80% number.

But let’s be clear here. The Easter Seals report, while perhaps interesting, is not a scientific study.

While it is a fairly large survey, and one that contains a sizeable ‘control’ group, it has problems that make it very limited in its ability to lend support for conclusions about reality.

First of all, there is an obvious likelihood of selection bias. The survey respondents were solicited via an e-mail invitation from Easter seals, ASA, or Harris Poll Online, which means the respondents were likely to be already involved (to some degree) with at least one of those organizations (enough to be on some sort of contact list), and regular internet users. The survey respondents may, or may not be truly representative of parents with ASD children. The ‘control’ group may not even necessarily be representative of the parents of children with no special needs (the U.S. divorce rate for married couples with children is probably closer to the U.S. average of 48%).

There is evidence of one possible effect of such selection bias, and that is that this survey’s demographic profiles are not consistent with the most current autism epidemiology at all. A full 55% of the parents of ASD children were reported to be parents of autistic children, as opposed to 45% of the parents whose children were diagnosed with PDD-NOS or Asperger’s. This is fairly divergent from the current descriptive epidemiology which puts Autism at about 33% of the total diagnoses, and 67% for PDD-NOS and Asperger’s combined. Such a skewing toward autism diagnoses could represent any number of things (diagnostic inconsistency for example), but I think it’s certainly possible that selection bias (specifically, “self selection”) is at play here – e.g. parents who are already connected in some way to Easter Seals or ASA, may simply be more likely to be the parents of children with an autism diagnoses, and parental participation in such groups by parents of children with PDD-NOS and Asperger’s diagnoses may be considerably less, because affiliation with such organizations simply may be a lower priority for those parents. If this is the case, it would inadvertently exclude representation of a significant portion of the question’s target parent population. If the question’s target population is not representative, is the information accurate? It’s hard to know.

In the context of a sense of scientific rigor, there just isn’t much here. Surveys, and parent reports are just that, reports. As an example, diagnoses were not confirmed with any standardized and normed instruments that I can see. And, to be fair, scientific answering of the divorce rate question wasn’t really an objective of this survey in the first place.

I realize that a skeptical look at both the urban legend of 80% or higher divorce rates and the reported lower divorce rates from the Easter Seals/ASA survey doesn’t really provide any kind of clear conclusion. There will be those who believe that anti-autism advocacy groups like Autism Speaks have some sort of authority on the subject, and they probably won’t see anything wrong with the perpetuation of what looks more like urban myth for pity. There may also be those who believe that parents of ASD children are less likely to divorce (based on this survey, or their own beliefs), ascribing some sort of family-strengthening magic to having special needs children in and of itself.

As for me, I tend to think the actual divorce rate among autism families is probably pretty close to whatever the average is for all families. All families, and all marriages, have sources of difficulty, conflict, and compromise. They all have good too. Is there any reason to think that parents of ASD children are really that much different than most parents when it comes to divorce overall, one way or the other? So far, I haven’t seen any good scientific evidence to make me think so.

Some readers may think of me as one of the Evil Neurodiverse League of Evil Bloggers, and be wondering why I wouldn’t jump on an opportunity to say that having an autistic child is some awesome family-strengthening thing that makes a man more happily married than a father with typical children. I’m sorry to disappoint in this regard – while possible, and undoubtedly true for some, the science just isn’t out there to support the notion that such a statement is applicable to couples with autistic children in general. If you were hoping for something potentially more romantic, or something as equaly tragic (and real) as an 80% divorce rate among autism parents, I recommend:
