Sufficient research has shown that ASD develops before birth from a combination of genetic and environmental factors. But some misconceptions about ASD still remain.
Common symptoms in children, such as challenges with social communication or restrictive behaviors, can begin to be noticeable in early childhood. But the belief that something can cause ASD after birth may be related to the fact that not everyone is diagnosed during childhood.
Since ASD is a spectrum of conditions with wide-ranging symptoms, some autistic people are not identified as autistic until they are adults, especially autistic females.

How can I reduce my risk of autism during pregnancy?

ASD is a spectrum of neurological conditions. Autistic people are born autistic and remain autistic for their entire lives. ASD is not a disease, and it has no cure. Some genetic and environmental risk factors may be involved in developing ASD before birth.
While there has been an increase in the number of people diagnosed with ASD over the past few decades, this is not because ASD is becoming more frequent but because our understanding of ASD has developed over time, as has our ability to diagnose it. Because of this, there are more options for support than ever.
