There is strong evidence that genetics play a role in the development of ASD. Studies have shown that siblings of children with ASD are more likely to have ASD than the general population, and that identical twins are more likely to both have ASD than fraternal twins.

Researchers have identified hundreds of genes that are associated with ASD. However, it is likely that no single gene causes ASD, and that it is a complex disorder that is caused by the interaction of multiple genes.

Environmental Factors

While genetics are thought to play a major role in the development of ASD, environmental factors are also thought to play a role. Some of the environmental factors that have been linked to ASD include:

  • Exposure to certain chemicals during pregnancy
  • Infections during pregnancy
  • Premature birth
  • Low birth weight
  • Head injuries

Diagnosis of Autism

There is no single test for ASD. Diagnosis is based on a child’s medical history, developmental milestones, and behavior. Doctors may also use standardized tests to assess a child’s communication and social skills.

Treatment for Autism

There is no cure for ASD, but there are treatments that can help improve a child’s symptoms. Treatment may include:

  • Applied behavior analysis (ABA) therapy
  • Speech therapy
  • Occupational therapy
  • Social skills training

Research into Autism

Research into ASD is ongoing. Researchers are working to identify the genes that cause ASD, and to develop new treatments for the disorder.


Autism spectrum disorder is a complex disorder that is caused by a combination of genetic and environmental factors. There is no single cure for ASD, but there are treatments that can help improve a child’s symptoms. Research into ASD is ongoing, and researchers are working to develop new treatments and to better understand the disorder.
