1. Genetics

Various genes are involved in the formation of this disorder. This disorder is related to a genetic disorder such as fragile X syndrome and Rett syndrome for some kids. Genetics changes like mutations for other children may enhance the risk of Autism. These genes may affect the brain and its development. Moreover, it plays a negative impact on brain cells and their communication factor. It causes the severity of signs.


2. Environmental factors

Researchers currently explore whether factors like air pollutants, complications during pregnancy, medications, viral infections, and others can play a vital role in triggering Autism.


Risk Factors

Some of the risk factors are here

  • Boys are four times more at risk of Autism as compared to girls.

  • Family history plays a vital role.

  • Children with specific medical conditions have more risks than others, like X syndrome, tuberous sclerosis, and Rett syndrome.
