I am not sure as I live in a country where therapy isn't dependent on a diagnosis. I know I took the SCID-D some time ago which gave a diagnosis of DID, but I don't recall PTSD, although I am sure I fit the diagnostic criteria for that too. It isn't in my medical notes - but neither is DID - while depression, ADD and anxiety disorder are. (Probably because I need meds for those while the dr doesn't need to know about DID since he can't do anything bout that).

How old were you when you first sought treatment for a dissociative disorder?
