Thought I should add:
Q. Why are we seeing a rise in the incidence of autism?
* Physicians use a book called the Diagnostic Statistical Manual to help them diagnose cases of autism. In the past decade, the guidelines in that book have changed. They have become more inclusive. So children who used to be considered "learning delayed" or to have "behavior problems" may now be more correctly diagnosed with mild autism.
* Parents and medical professionals are simply more aware of the condition and are more likely to pursue a diagnosis and treatment than in years past. As there are more state and federally funded programs available for children with autism, there is an increased incentive to make a diagnosis, so those children will have access to those programs.
* A recent study in the British Medical Journal found no rise in incidence of autism in children who received MMR as compared to those who did not. The authors also showed that in autistic children (both ASD and classical) the age at which a child received MMR did not affect the age at which the diagnosis of autism was made.
