What is the cause of ASD?
It is unlikely that there is one single cause of ASD. A variety of neurological research suggests that many different parts of the brain are affected and that there is no one single Autism gene. In some people with ASD it is detected early on in the infant’s life; however for others it is not noticeable until 18 months or older. Gutstein (2005) suggests that around 18 months the infant with ASD is not able to make the transition necessary to integrated brain functioning and thus development is disrupted.
