:hello: Greetings from the U S of A:
Here in the United States its not so simple, Anthony. When we say "official" over here, it could mean a lot is riding on the diagnosis. Most US insurance companies, including public Medicaid and Medicare, and government operated medical and clinical facilities will not accept anything other than a DSM-IV diagnosis in order to pay for services, and in some cases, in order for a client to receive services or benefits. You can't get on private or government disability payments over here without a DSM-IV diagnosis. :wall:
This leaves US therapists, physicians, and clinicians to figure out :crazy: which DSM-IV diagnosis most closely matches their client for "official" purposes. So those of us who have been diagnosed with CPTSD officially in the eyes of the mental health professionals generally also have an "official" diagnosis from the DSM-IV handbook as well so that our needed services, prescriptions, therapy, etc. will be covered by our insurances or eligible for government aid.
In my case, I am officially diagnosed with CPTSD and "officially" diagnosed with PTSD. So there you have it. A Red Tape US government tangled mess done to keep everyone using a uniform system for diagnosis and on the same page, so to speak.
