It seems like there has been an explosion in cases in the last decade… why is this? I heard that it may be linked to childhood immunizations…

According to the CDC (Center for Disease Control and Prevention), the prevalence rate of autism is approximately 1 in 88, which represents a 600% increase in prevalence over the last 20 years – yes, it is pretty clear that most people would view these numbers as an ‘explosion’. At the same time, there is debate about the cause for such as increase in prevalence; one possibility being that the criteria for diagnosis has been largely expanded in recent years to create the illusion of such an exponential increase. While passionate arguments persist on both sides of this issue, what it boils down to is that the exact cause for such an explosion of cases is unknown.
