Hi Laura,
There's quite alot in that video, I think I'm going to have to watch it a few times to really pick up on everything. Just thought I'd say, however, that I would tend to agree with you as regards the overlap between personality disorders and PDDs like Aspergers Syndrome.
I first reached the conclusion that I may suffer from Aspergers indirectly through OCPD - obsessive compulsive personality disorder. I can't remember where I heard it said, however, that it may be that some of the personality disorders are actually sub-groups of PDDs like Aspergers given that most PDs were identified long before Aspergers reached the DSM.
