Hello Zms1: Thank you for bringing your question here to PC. I noticed this is your first post. So... welcome to Psych Central. Since you mentioned being a parent one additional forum, here on PC, that may be of interest to you would be the healthy parenting forum. Here's a link:

I'm sorry I cannot answer your question authoritatively. However I believe the professional you would want to see to be evaluated for autism may be a psychologist. You might be able to be referred to an appropriate professional, though, by a psychiatrist or perhaps your family doctor.

Here are links to 2 articles, from Psych Central's archives, that discuss what autism is & how it is diagnosed. Also included is a link to an article that may be of interest on Asperger's syndrome:

I hope you find PC to be of benefit.
