The Autoimmune Epidemic

While wandering the aisles in the local Borders book store, I saw Donna Nakazawa's new book, The Autoimmune Epidemic: Bodies Gone Haywire in a World out of Balance and the Cutting Edge Science that Promises Hope. This description is from the book's official site:

Multiple sclerosis, lupus, Type 1 diabetes, rheumatoid arthritis, and nearly a hundred other chronic autoimmune illnesses are part of this devastating epidemic, in which the human body, acting on misread signals, literally begins to destroy itself. Alarmingly, the occurrence of many of these diseases has more than doubled in the last three decades, signaling a disturbing trend that can be directly tied to environmental factors in everyday modern life—including our daily exposure to a dizzying array of toxic chemicals.

With the conversation around a recent post fresh in my mind, I was drawn to the book to see what the author had to say about autism in the context of this autoimmune epidemic. There is one section, consisting of two pages, where she mentions the possible relationship of autoimmune issues, vaccines, and heavy metals (specifically mercury in the form of thimerosol) to autism. I don't recall the specific wording, but she basically left it as, "We'll have to wait and see what comes of the research."

Has anyone had a chance to read this book yet? Any thoughts?

On vaccines and autism

Last week I asked the question: What would it take to change your mind? I figured I should probably think of an answer for myself, this post includes some thoughts from my contemplation. This is not a complete argument for or against anything that I haven't already stated, just some thoughts in process. Any thoughts of yours are certainly welcome.

I don't believe that autism is mercury poisoning, I've said that before. As for the number / types of vaccines being a trigger (I don't believe it is a cause in the Newtonian sense), I've been thinking about it lately but haven't seen any data to help me make a my mind.

Along those lines, the Age of Autism (which is, I must note, very openly of the opinion that mercury in the form of thimerosol in vaccines and/or the number of vaccines given to kids is the primary cause of most autism) yesterday pointed to the 2008 pediatrics vaccination schedules (0-6 years and 6 years and over).

WOW!!

That was about all I could think when I looked at the schedule. The schedule in and of itself doesn't lead me to believe anything different than what I knew before, but it does give me an extra data point. The human immune system is an incredible, incredibly intelligent, incredibly complex system. (Though I'm sure there are many books specifically on the subject, The Genius Within includes a very description of how the process works.)

The challenge with a complex system (as opposed to a merely complicated system) is that the outcome of any given input to the system can not be predicted and that a specific cause for a measured outcome cannot be identified. From Dave Snowden (who thinks about complexity a lot):

• Complex systems can not be predicted, they are non-causal (taking cause in its normal Newtonian sense) in nature they evolve and the same thing will not happen again twice, we can predict aspects of the system and different aspects of time but never the outcome of the whole system
• The concept of a non-causal system is a very difficult one to grasp as the west abandoned the idea at the time of the Enlightenment (Vico and others were prophetic in arguing against this).
  
• A complex system can be simulated - which increases understanding but simulation should not (although it is often) confused with prediction
• We can understand starting conditions as a complex system evolves and we can influence their evolution if we focus on barriers and attractors (1st and 2nd order constraints) but not if we look at the end point (so attempting to predict makes things worse not better)
• Humans tend to premature convergence (seeing a pattern too quickly before it is stable) and also to retrospective coherence (implying past causality where there was none). Both of these tendencies are pervasive and dangerous

Which brings me to a very interesting dilemma:

• If autism (has a cause and) is indeed caused by an insult to the immune system, we can not predict which vaccine or combination of vaccines will cause it; and,
  
• Once autism is caused in an individual we can not look back through their vaccination history to determine which vaccine it was that did the causing.

And this doesn't even bring into play the complexity of the interaction between the immune system and the rest of the body or the role of genetics, and genetic predisposition.
