More Evidence of Increase in Profound Autism

I am Jack's username writes "The New York times has an article (no registration required) about an increase in profound autism in California of 273% between 1987 and 1998. Between 1999 and 2001 more than 6 500 cases were reported, similar to the number reported between 1970 to 1995. The increase cannot be accounted for by misdiagnosis, increased awareness, childhood immunizations, emigration, birth injuries, and genetics. Some autism experts think the actual cases to be dramatically more than reported in the UC study. See also previous discussions about high-function geek rich areas like silicon valley."

      The way evolution works is that there are many completely random variations and those that cause greater reproductive success are propogated.

      The only way to see an "evolutionary step" (itself a misnomer) is to see some variation that causes greatly enhanced success at breeding. Needless to say, we are not seeing that here.

      If you believe this is an evolutionary change (and I do not) then you'd have to conclude as follows:

      These children probably get lots of supervision - could be that's part of the environment that they are adapting to? Biology isn't picky about the distinction between a 'natural' environment and one that we've created - or about the distinction between a sustainable environment and an unsustainable one. When a large proportion of the population is severely autistic and can no longer provide that supervision for their offspring - evolution must either step in again - or if it can't react fast enough, there will be a population crash.

      If you do believe this is an evolved adaptation then you'd have to conclude that Geeks should not be marrying other Geeks.

      Personally, I'd suspect some side-effect of pollution...or a statistical error of some kind. I doubt evolution could react to a change in the environment as fast as one generation - which is as long as the geek population has surged in California.

    From the article:

    Parents in the study were asked what might have caused their child's autism. Nearly half the parents in both groups said they did not know. A third blamed genetics; smaller numbers cited immunizations, birth injury or environmental factors.

    So, just about half of parents are intellectually honest, then. We don't know what causes autism--there is nothing approaching a consensus among researchers, and there are few well-designed studies that even suggest a possible cause. Asking parents what caused their child's autism is like asking a non-technical person why their hard drive crashed. The answer as likely as not will be "I dunno, maybe I've got a virus?" Interesting for investigating the biases of the hapless user, but not a useful diagnosis.

    A little knowledge is a dangerous thing. I'm just surprised that nobody in the study thought to blame living near power lines--unless that's an "environmental factor".

    Hypothesis: The incidence of autism is higher because children aren't being allowed to eat enough dirt. Exposure to more microorganisms when young strengthens the immune system. There exists a microbe (virus, perhaps) as-yet-uncharacterized that causes autism. (This happens sometimes with diseases. For example, most stomach ulcers are caused by the bacterium h. pylori and can often be cured with antibiotic therapy. This fact only came to light very recently, after decades of assuming that ulcers were essentially untreatable.) Children's weaker immune systems don't fight this pathogen as effectively as they used to, so they develop autism more frequently.

    Solution: Feed all young children dirt.

    This hypothesis actually has about as much grounding as many of the other suggested causes of autism. Based on very weak evidence, some parents have started to avoid immunizing their children, putting them at much greater risk for measles and other potentially deadly diseases. Bless the internet and its unquestioned authority on medicine.

You can't account for an upswing in autism by blaming gluten; we've been swimming in the stuff for centuries, and I doubt that California has suddenly experienced a massive increase in bread consumption.
