Questions have loomed around the finding of an increased risk of parents having a child with ASD if they are under 20 or over 35. Of course not every parent who is really young or older will have a child on the spectrum and plenty of those between those ages also have children on the spectrum. Risk factors for ASD are not absolute, they are nuanced and work with other genetic and environmental factors. This week, Kristin Lyall from the AJ Drexel Autism Institute found that those with a strong genetic influence were not as sensitive to factors like parental age. This goes to show, yet again, that it isn’t about ONE risk factor, it’s about dozens working together. And for those 30 year old parents who had a child with autism – see, not every research finding applies to you directly.
