I could be way off, but that sounds purely like a court "legal" thing to me. Like if someone commited a crime, and they plead "not guilty because of insanity", well we all know that there is no true diagnosis called "insanity". That is an umbrella legal term that they use when an impartial therapist evaluates the defendant to determine whether or not he or she was of sound mind when said crime was commited. That could be the name of that evaluation.
I hope everything is OK with your difficult child...
