Signs and Symptoms. According to the Autism Society, autism symptoms typically become clearly evident during early childhood, between 24 months and 6 years of age. Symptoms include a marked delay in language and cognitive development. There may be signs of obsessive and/or antisocial behavior.

What we do know, however, is that parents do not cause autism.ccasionally, a child with autism may display an extraordinary talent in art, music, or another specific area.
