Autism is a complex disease and the fact is that no two children with autism are alike, probably there are many causes. They may include:

Genetic Defect

  • In some children these genes cause a delay in the brain development.
  • In some the genetic errors can be inherited from any of the parent.
  • Autism in a child may occur spontaneously.

Environmental Factors

  • Research is going on to know whether viral infections and air pollutants play a major role in triggering autism.

Other Causes

  • Problems during labor and delivery is considered to be one of the factors for autism.
  • Researchers believe that damage to a portion of the brain which serves as a danger detector can be one of the causes for autism.

A child suffering from autism can have problems in 3 areas of development that is language, social interaction and behavior.
