Is there anything else I need to know about autism spectrum disorder screening?
There is no one single cause of autism spectrum disorder. Research suggests that it is caused by a combination of factors. These may include genetic disorders, infections, or medicines taken during pregnancy, and an older age of one or both parents (35 or older for women, 40 or over for men).
Research also clearly shows that there is no link between childhood vaccines and autism spectrum disorder.
If you have questions about ASD risk factors and causes, talk to your child's health care provider.
