I'm trying to understand BPD better and I apologize if this question doesn't belong here.

Can BPD be cured in the sense that it goes away permanently and doesn't come back?  Is it that the individual finds coping mechanisms which last a lifetime, like a semi-permanent recovery? Is BPD a lifetime problem that the person has to constantly battle? Are the results different for different people - in the sense that there might be different variations of the biological basis of the disorder? 

Basically I'm trying to understand the prognosis / outcomes for BPD. I'm also trying to learn more about the biological versus psychological influences. I'm aware of biosocial theory but I don't know much about it. If anyone can point me in the direction of a more technical discussion, that would be helpful.
