Can Brain Injury Cause Autism in Adults? Autism, by definition, is a developmental condition, which means it is present from birth. Therefore, a brain injury does not cause autism in adulthood.

Can stress during pregnancy cause autism?

While genetic factors are a major contributor to the etiology of ASD, mounting evidence supports a role for environmental factors, allowing possibilities for prevention or early intervention. Prenatal stress and maternal immune dysfunction appear to contribute in some way to a significant proportion of these ASD cases.
