I wasn't aware there was a difference until now. I found a few articles that go into CPTSD in some detail and suggest treatment methods. The main differences are that PTSD is caused by a single, severe traumatic event, CPTSD is caused by a repetition of similar traumatizing events over time and seems to involve experiences of powerlessness and abandonment.

These articles are REALLY detailed (especially the first):
