An abstract of a study released by the US Centers for Disease Control and Prevention, found that the study's "2010 [Autism Spectrum Disorder] prevalence estimate of 14.7 per 1,000 (95% CI = 14.3-15.1), or one in 68 children aged 8 years, was 29% higher than the preceding estimate of 11.3 per 1,000 (95% CI = 11.0-11.7), or one in 88 children aged 8 years in 2008." Of the sites surveyed, four counties in New Jersey had the highest prevalence estimate, with 21.9 per 1,000 (95% CI = 20.4-23.6). National Public Radio quotes CDC experts that "skyrocketing estimates don't necessarily mean that kids are more likely to have autism now than they were 10 years ago."
"It may be that we're getting better at identifying autism," says , director of the CDC's National Center on Birth Defects and Developmental Disabilities.Researchers say intervention in early childhood may help the developing brain compensate by rewiring to work around the trouble spots.
Another abstract of a "small, explorative study" from The New England Journal of Medicine describes Patches of Disorganization in the Neocortex of Children with Autism and suggests "a probable dysregulation of layer formation and layer-specific neuronal differentiation at prenatal developmental stages." CBS News demystifies the study as "brain abnormalities may begin in utero." [Ed's note: Link intermittent]
Last month, we discussed findings that suggest that delaying fatherhood may increase the risk of fathering children with disorders including Autism.
Not trying to pry, but for the sake of science, would you mind letting us know if the age of you and/or your wife at the time of the pregnancies was believed to be a factor?
My own anecdotes are contradictory, my mid-40's aged teacher got pregnant and had a perfectly normal, healthy kid. My friend had in her late 30's a daughter who managed to be fine mentally but was born with only one kidney.
Not the parent but my wife was 23 and I was 31 when our autistic son was born.She wasn't on any drugs either and I was a light pot smoker.
Anecdotal means nothing in the greater discussion and scientific evaluation (and, of course, everything to the individuals) - with present rates quoted at 1/42 boys born, I congratulate your two friends on falling into the "easier to mesh with society" side of the lottery. However, if it's just a lottery, we just pulled out a 1/1700 winner.
We are older - and there may be a behavioral selection bias there (don't find mates until later, yadda yadda) The kids were born at mom's age 37 and 39.
