There are likely many causes for multiple types of ASD. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic and genetic factors.

• Most scientists agree that genes are one of the risk factors that can make a person more likely to develop ASD.

• Children who have a sibling with ASD are at a higher risk of also having ASD.

• Individuals with certain genetic or chromosomal conditions, such as fragile X syndrome or tuberous sclerosis, can have a greater chance of having ASD.

• When taken during pregnancy, the prescription drugs valproic acid and thalidomide have been linked with a higher risk of ASD.

• There is some evidence that the critical period for developing ASD occurs before, during, and immediately after birth.

• Children born to older parents are at greater risk for having ASD.

➝ Who is Affected

ASD occurs in all racial, ethnic, and socioeconomic groups, but is about 4 times more common among boys than among girls.

For over a decade, CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network has been estimating the number of children with ASD in the United States. We have learned a lot about how many U. S. children have ASD. It will be important to use the same methods to track how the number of children with ASD is changing over time in order to learn more about the disorder.
