I agree that there is no -direct- causal relationship between childhood abuse and BP. Abuse does not = development of BP. Insofar as environmental issues can induce development of MI in general, when one has a genetic disposition anyway, I think is possible. But I think that this is common in PTSD and BPD. BP is an MI of another flavor altogether.

Again, I do believe that childhood abuse can (and again, not always, but it's not clear why some do not develop it) lead to PTSD. But PTSD and BP are two entirely different things, with vastly different symptom profiles and, yes, causes.

Thanks for all of your replies. I have suspected the above, but wanted some feedback from you guys.

For those of you who have been abused, my heart goes out to you and I admire you for fighting your way to find the best version of health you can manage. I can't imagine battling the after-effects of abuse along with BP. I just don't think there's a direct correlation. Though I do think that any MI (i.e. PTSD) can exacerbate other MI's and this could be the case with PTSD-BP. This is probably why therapy, in conjunction with psychiatric care, is the best way to go. For all or most of us, no matter what the MI, frankly.
