Causes of Autism

Scientific research in the United States in recent years has pointed out that autism is not a single but has multiple causes, including:

  1. Rare genetic variation
  2. Genetics
  3. Biochemical function development disorders
  4. Environmental factors
  5. Mother infected with a virus during pregnancy

Any combination can trigger the emergence of autism: Environmental factors mainly include: Older parents, heavy metal pollution, immune system, antibiotics, food allergies, environmental pollution, illness during pregnancy, and the dangers caused by production.

Studies have shown that simple environmental factors do not directly lead to autism, only when a combination of high-risk genetics and environmental factors can lead to the emergence of autism. Studies have also confirmed that autism has nothing to do with mental disorders or parenting styles.
