Is Age More Than A Number In Autism?
Monday, November 30th, 2009
People are diagnosed with autism at a variety of different ages. Autism diagnosis ranges from toddlers to teenagers to adults, Autism does not discriminate against the age of a person. This might not be the case when we switch focus and look at the parents’ ages. A study conducted between 1989 and 2002 of 7.5 million births in California found that the risk of a child developing Autism went up with the age of the parents.
A child’s risk of getting Autism went up 38% for each 10 year increase of a mother’s age between the ages of 20 and 40. There were also other factors taken into account including race, education, and the father’s age.
As a father’s age increased, the risk of the child developing autism went up 22% with each 10 year increase between the ages of 20 and 60.
Most believe that genetics plays a key role in the development of Autism. However, studies of parental age as a factor have mixed results. There are some studies, like the one in California, that show age may have an impact on the risk of developing Autism. Then, there are other studies that do not show any impact whatsoever. Still, there is no solid evidence that age plays a definitive role in determining the risk of a child developing autism.
Over the last 2 decades, there has been a significant spike in the number of autism cases. The reasons for this still have not been determined as there is no clear link. Though it’s just an observation, it’s not unfathomable that the overall trend of delaying pregnancy and childbirth could have something to do with the rise – and this would tie into the age speculation.
Even if the parents’ age is a factor, however, it would not have an overwhelming effect on the risk of autism development. Even in the California study, a large majority of older parents did not give birth to children who developed Autism. About 800 children born to women between ages 40-44 developed autism, while 150,000 did not. When this number is compared to the children born to mother’s aged 25-29, the risk was 84% higher.
Until there is solid evidence, there are no suggestions to give parents planning on having children.


A few weeks back, I discussed how gluten can cause behavioral disorders in children who are incapable of digesting it. Many parents have also found that removing Gluten from their Autistic child’s diet has been very beneficial. The same goes for Casein (dairy).
Last week, I looked at how genetic abnormalities may be linked to autism and today I’m going to take that a bit further and look at the link between the genetic codes, autoimmune diseases, autism and gluten - an interesting recipe!
In the past I have mentioned how important a healthy diet is to all children, not just autistic children, but some parents jump in to using strict elimination diets without first making any simple changes to their child’s diet to make it more nutritious. You never know, a few simple changes to make your child’s diet more “nutrient dense” may lead to vast improvements without having to cut out gluten or casein.
I’ve blogged before about reducing your child’s toxic load to help alleviate symptoms of autism, to cut the risk of autism in subsequent children and to have a healthier home, and today I’m going to talk about one particular chemical and toxin, phenol.
A few weeks ago, I blogged about Vitamin D and how the rise in Vitamin D deficiency has been linked to the rise in autism, but vitamin D is not the only deficiency that has been linked to autism and some people are suggesting that a deficiency in vitamin A may be responsible.

The SCD, or Specific Carbohydrate Diet, is a step on from the GFCF Diet and was made popular by the book “Breaking the Vicious Cycle” by Elaine Gottschall.
