What is the main cause of autism?

The exact cause of Autism or autism spectrum disorder (ASD) is not known, but it is believed to be a combination of genetic and environmental factors.

• Research suggests that several genes may be involved in the development of autism and that certain genetic mutations may make an individual more susceptible to the disorder.
• Studies also suggest that environmental factors such as viral infections, prenatal exposure to certain toxins, and complications during pregnancy or birth may also play a role in the development of autism.
• Research continues to evolve in this area and it is likely that the causes of autism are multifactorial and complex.
