Women over the age of 40 who give birth have a 51 percent chance of having an autistic child compared with those who bear children between the ages of 25 and 29, according to a recent news report.
The father's age also is a factor, but only if he is older and the mother is under 30, according to an article published by CNN. The piece cites findings by researchers at the University of California, Davis, which first appeared in the February issue of the journal Autism Research and examined 10 years of data from births in California. It is unknown why the mother's age is more influential than the father's on a child's chances of developing autism.
Autism Spectrum Disorders (ASD), a group of developmental disabilities that can cause significant social, communication and behavioral challenges, occur in all racial, ethnic and socioeconomic groups and are four times more likely to occur in boys than in girls, according to the Web site for the Centers for Disease Control and Prevention (CDC).
According to the CDC, more people are being diagnosed with ASD than ever before. It estimates that one in 110 children in the United States have an ASD.
"It is unclear exactly how much of this increase is due to a broader definition of ASDs and better efforts in diagnosis,'' the CDC site reports. "However, a true increase in the number of people with an ASD cannot be ruled out. We believe the increase in ASD diagnosis is likely due to a combination of these factors.''
The new findings could be a game changer for researchers trying to tackle an elusive medical matter. For years, it was believed that the genes of both parents were connected to the disorder. In the 1980s, an Israeli study linked paternal genes to the increased risk of autism.
Still it has long been known that giving birth at an older age poses health risks to babies, including higher risks of birth defects, low birth weight and certain chromosome problems such as Down syndrome.

I have 2 close family members with Autism. One mom had her son at 18 and the other was 22 years old, by far they were NOT ‘older’ mothers. Comparing these precious children with other family children we feel both were born with Autism and attributed their characters to their individualities, in fact, we thought they were observant and smart, concentrated in whatever caught their interest. One is quiet, the other is outgoing. It was until they were in kindergarten that we contemplated otherwise. New research might show that “Older Mothers At Risk of Having Autistic Children”, yet I feel these findings are inconclusive. Other factors should also be considered, as environmental contamination, genetics, etc. Awareness researchers, young mothers are at risk of having “Autistic” children too.

I was 26 years old when my autistic son was born. Come on ... let's face it. Every other month, doctors and scientists try to convince the world that they have the answers to the cause and/or cure of autism. So far, they have nothing. They can't even try to explain autistic people who can play classical music (without training) yet cannot talk or who can figure out complicated math problems with no help from calculators. Autism is a mystery that goes beyond human understanding. And it's as simple as that!

I agree too.
My grandkid (9) now, was born when my daugther was 22... and I notice ate begin about 3 months something was missing about her, but nobody believed I was right,.. she was very quiet,even she was "ok" looking around, looking at our eyes .
But when she tourned 7 months I was sure tha she has something sugesting something wrong.. she didt't poin her fingers , only faloowed when we pointed at something. I did mthe diagnostic even against my daugther, my ex husband and other people, just because she was doing "baby talk" smailling etc.
Today she is nine, with moderate autism and doing well, reading, like mathematic, very will to learn and talk, a amazing memorie .
The only think I was trying understand was my daugther had a very sad and derpessed pregnancy her husband was on jail for one year or so.... and left her pregnat.. that's could be another clue for the scientists.. who knows, when we are pregnat we have some psichological issues so..

Anna I think you just might be up to something! Too bad most scientist/doctors are too arrogant to listen to simple folks like you & I!

The truth be told they don't know what causes Autism. My child is an Aspie; that means that she has Aspberger's Syndrome. She was very hard to diagnose because she hit all of her benchmarks. This is a disorder that runs from mild to severe and there is a lot that is not know about it. Could the age of the parents be a factor? Sure, but it cannot be the only factor. LIke a lot of other posters have said, they were in their twenties when their children were born. How do you explain that? They call Autism the specturm disorder and it truly is.

I gave birth to my son when I was 31 years old. He has been diagnosed with moderate ASD & ADHD when using multiple MDs who specialize in such diagnoses. This has been the second most challenging experience in my life. I find myself praying often for GOD to remove the barriers that hinder my son from learning. Although he has made a few strives, my husband and I just can't seem to find the answers. We are continuously depending on GOD to make this experience better. Our thoughts remain positive through GOD,knowing that HE has a purpose for all matters. Hopefully, there will be a school designed nationwide to meet the needs of my son and other children who learn differently when addressing ASD. I may be the one to direct one.
Parents keep your heads up!!!!!!

Thanks moms for sharing your information. I am 40 and have always wanted to be a mom but haven't been able to do so yet. I have not given up hope, but the possibility of having a child with down syndrome or autism had been making me feel like getting pregnant at my age was selfish on my part. I am a special ed teacher, and honestly in my experience, autism and other disabilities occur with mothers of all ages: brand new moms at 18, and older moms at 45. I am still holding out hope. Thanks again. 80)
