Autism Findings Little Surprise to Parents
Feb. 9, 2007 — -- More than half a million children in the United States have an autism spectrum disorder.
This was the finding reported Thursday by the U.S. Centers for Disease Control and Prevention, which also views the new data as "confirming the upper end of estimates" from recent U.S. and non-U.S. studies.
In short, the findings from the Autism and Developmental Disabilities Monitoring study suggest roughly one in 150 American children have autism -- many more than previously thought.
But some parents of autistic children say the finding of an increased prevalence is no surprise.
Jeff Sell, who lives in Texas, is a 45-year-old father of two children with autism. Both of his children were born in 1994, but were diagnosed at different times in 1996.
"From a certain perspective, this is big news, but it is something that parents of these children have already known," Sell says. "But for a few years, everybody has been going through these more or less academic-type arguments [about the prevalence rate].
"Call it what it is, I have two autistic children in my house, and at the neighborhood school there are also very many."
Catriona Johnson, 43, of Columbia, Md., has a son with autism who was diagnosed in 1995 at the age of 2.
"This didn't surprise me, particularly in terms of where I come from in my state because our numbers are consistent with this," she says.
The higher prevalence in these latest findings begs another question: Is the number of autism cases growing, or are more existing cases simply being detected?
"That's one of the challenging questions, and there is no way to answer this for sure, for the time being," says Catherine Rice, a behavioral scientist with the National Center on Birth Defects and Developmental Disabilities and a leader of the study. "That's one of the reasons that we developed the network, so we can answer this."
The true answer may lie somewhere in between better detection and an actual increase. There is little doubt that detection of existing cases of autism has improved.
