Does your child not answer when you call his or her name? Does he or she not make eye contact with you? Do they say the same words over and over? Do they start talking and then stops? Do they not point to things or show you things that they are interested in? These are all signs of Autism. Autism refers to a wide range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication. There are several forms of Autism, varying in degrees of severity, caused by a combination of genetic and environmental issues.
