I think there is a significant difference between PTSD and Complex PTSD -- in fact some professionals recognize that. Complex PTSD typically results from prolonged trauma, usually in childhood.

Here is what Wikipedia has to say:

"A differentiation between the diagnostic categorizations of C-PTSD and that of Post traumatic stress disorder (PTSD) has been suggested, as C-PTSD better describes the pervasive negative impact of chronic trauma than does PTSD alone.

"As a descriptor, PTSD fails to capture some of the core characteristics of C-PTSD. These elements include psychological fragmentation, the loss of a sense of safety, trust, and self-worth, as well as the tendency to be revictimized, and, most importantly, the loss of a coherent sense of self. It is this loss of a coherent sense of self, and the ensuing symptom profile, that most pointedly differentiates C-PTSD from PTSD."

I also think this statement is not always true:

"this is why people who have traumatic experience have such an easy time recalling such small details about their event..."

because some victims can recall few or no details of their traumas -- due to the fact that the original stress can be so great that a young brain simply cannot handle it any other way than to blank it out, to make it "go away" or "unhappen" it mentally. I know this from personal experience.
