California’s sevenfold increase in autism cannot be explained by changes in doctors’ diagnoses and most likely is due to environmental exposures, University of California scientists reported. The scientists who authored the new study advocate a nationwide shift in autism research to focus on an array of potential factors in the environment that babies and fetuses are exposed to, including pesticides, viruses and chemicals in household products.
One of the most common arguments you will see about a lot of mental health diagnoses is that doctors have changed their diagnostic practices significantly. While there is evidence of this occurring in diagnoses of childhood depression, anxiety, or even bipolar disorder due to the millions of dollars involved in medication and the attendant corruption, autism is different.
This population study used 17 year data in California and concluded that diagnostic changes were only responsible for a 2 fold increase, not the seven fold increase seen. The rest is unexplained, and the authors attribute it to a confluence of environmental and genetic factors.
And no, for the last time, VACCINES DO NOT CAUSE AUTISM!
