Environmental
Toxins in our environment have a potential involvement in this disorder. Chemicals such as thalidomide and valproic acid have been linked to have an increased risk of autism. However, according to a hypothesis autism may be triggered by a mother’s exposure to environmental agents during pregnancy (niehs.nih.gov). Air-pollution during late pregnancy is linked to autism especially the type of pollution that is associated with traffic. Research was conducted and around 1,00 children had exposure to pollution who went to developing autism.. However, air pollution had the highest effect during the last three months of pregnancy. The finding of late pregnancy pollution exposure has a theory that autism is linked to brain network development during the last final pregnancy months. Although, these may be a few factors that may develop autism it is not for sure that it triggers it research is still being done.

Genetic
Children can develop autism within the first 18 months after birth which can run in families. Identical twins, who share the same genes, are much more likely to both have autism than fraternal twins. If you have one child with autism it is 2-6% the second child will be at risk. Another way genetics is involved is by having a missing X-chromosome. If a genetic alteration occurs on the Y chromosome that can lead to autism, only men will be affected. If a mutation occurs on the X chromosome, females can be shielded because they carry a second backup copy of chromosome X. This is why men are at high risk of developing autism than females.
