This is very interesting! You have a copy of the DSM-5? Nice. Is the description on specifically the “atypical” modifier itself new to the DSM-5?

As an aside, I found both the complete DSM-5, ICD, and the DSM-5 Update on the Internet in the form of PDFs. I have some reading to do. It will take some time to just figure out where everything is in the book. I am glad GoodReader has a search function.
