Autism spectrum disorder (ASD) is a complex developmental disability with no single known cause. Research suggests that autism develops from a combination of genetic and environmental influences. Genetic factors play a significant role, as certain gene changes associated with autism can increase the risk that a child will develop the disorder. These gene changes can be inherited or occur spontaneously. Additionally, environmental factors such as advanced parental age at the time of conception, prenatal exposure to air pollution or certain pesticides, problems with a mothers immune system, certain metabolic conditions, or inflammation during pregnancy may also be linked with higher autism risk for her children. Its important to note that vaccines do not cause autism.
The exact cause of autism is not fully understood, and the disorder is likely caused by a combination of genetic and environmental factors. While the specific cause of autism in children remains a topic of ongoing research, it is clear that a combination of genetic and environmental influences contributes to the development of autism spectrum disorder.
