It may not be very direct connection but to me this way of thinking (when it is not adaptive to one's life choices in the present) means that perhaps something very drastic happened before teen years and never got resolved and the adult got arrested developmentally at younger age.
Can’t (and am not trying to) speak for
@Freida... I have no idea what her childhood was like... but it’s been proposed countless times that in order for PTSD to happen in adult years that “something” must have happened during childhood years. But it’s been debunked/rejected/proven otherwise almost as often. As countless people with golden childhoods, from the entire raaaaaange of of backgrounds and experiences (every “type” of family, childhood, personality, etc.), go on to develop PTSD from trauma in adult years. Absolutely healthy, balanced, well rounded, secure, strong self confident individuals can be -and are- just as shattered by trauma, as those who are not.
The trauma itself is “enough” to cause PTSD. It doesn’t need an already damaged person.
There are many disorders & conditions out there that require some kind of priming, and others that must be present from childhood (as well as the opposite, if “the disturbance” is caused by an outside source or circumstance, it’s
not that particular disorder)... so it was a valid line of scientific inquiry. Just one that’s been disproven. Hence Criterion A. The trauma happened. Then criterion’s B-F happened.
((It’s a line of inquiry that has been flogged to death by the US Military, by the by, as we’re not a socialized med country / they’ve been looking for yeeeeeears for a way to get out of paying for treatment/benefits of US Military personel with PTSD. If they can prove causation? That a person enlisted already defective in some way? Then it’s not “service connected”. So all the big money and bias has been on the side of proving PTSD requires some pre-existing circumstance in order to develop. It simply doesn’t.))
It’s something I looked into a whole helluva lot when I was new to learning about PTSD, because I’m one of those people who had a Golden childhood / come from a fantastic family. If it WAS a prerequisite? I wouldn’t have PTSD. I’d have something else. So I poured through articles, studies, proposed theories, findings, conclusions, etc... and despite the theory being raised time and time again? The consensus is : Trauma is enough to cause PTSD.
