Just my opinion...but I wouldn't take her to another doctor until you see how the Prozac goes. Most of the specialists within autism are psychiatrists, some are psychologists, some pediatric neurologists, etc. The important thing is that they have experience with AS, OCD, etc. If they did a psychiatry residency and a child fellowship then they have been studying aspects of those disorders their entire professional lives. Additionally, there is always disagreement in the field about which psych disorders are genetically & neurologically related. I wonder if your MD said one can't have AS without some obsessive traits. He is mixing the way laymen refer to obsessions with the DSM-IV diagnoses of ASD, OCD, etc. He may not have been sufficiently precise in his use of language, but he may also have been trying to translate his "medicalese" into something he thought a parent could understand. He may not know how well informed you are. Just a thought..
