First, let's make it clear that Autism is not a disease. Autism
is defined as a complex developmental disability where signs of this
disorder appear anywhere between birth and three years of age. In my
personal experience with Autism, my son who is now seven years old was
developing quite well for his age until he was about two years old. We
started seeing a decline in my son's development that mostly affected
his ability to communicate and interact with his family on a daily
basis.
