Yes, they do. They also have many claims of ineffective treatment, complaints of misdiagnosis, of being misunderstood, will often resort to alternative medicine when traditional practitioners won't be manipulated by them, tend to use very technical jargon, spend quite a bit of time reading professional journals and medical/psychiatric texts, even though they have no professional cause to do so, tend to attempt to diagnose other people (very dangerous!), will make statements of agreement when someone who actually does have the disorder reports symptoms (Oh, yeah, I have that too!), claim that treatments that have shown to be effective in others has no effect for them, and are usually well informed regarding diagnostic procedures and testing. That is usually an attempt to manipulate the diagnostic process, even though they are unsuccessful at doing so.
