Of course, why trust the New England Journal of Medicine when there are so many "experts" pushing their theories on the Web? I am now accustomed to the anti-vaccination crowd claiming that any research that points to a genetic cause, with minimal environmental triggers, is research bought and paid for by "Big Pharma" or some other conspiracy is at work.
It is ironic that the stories of autism-free Amish appear on thousands of Web sites, while serious research is largely ignored. People want easy answers.
Triggers are not causes. Are there triggers for underlying conditions? Probably. But I wonder if we are asking for trouble as more and more parents avoid vaccines? Hence, recent stories in the New York Times about measles outbreaks. According to the Times, several outbreaks of nearly-eradicated diseases have recently occurred.
