Thank you for your question and welcome to Health Central's ADHD Community.

I am not a medical professional and would not be able to give you medical advice.

Are you asking this question because you have a child or a relative that may have autism?

Can you be more specific in what information you are looking for. Your question is very broad and would require a rather lengthy answer. In short, autism is a developmental disorder which impacts social recipriocity and communication. Some children with autism have delayed speech. Children with autism also use repetitive actions or have repetitive behaviors.

Please let me know a little more about why you are asking this question and I will be glad to try to answer your question.
