Hi Kate736,
Welcome and hello
I'm sorry for what brings you here, and glad you found the site. It helps to talk to others going through the same things.
There is
a discussion on this topic about treatment and remittance that you might find useful. If your daughter is a teen, I recommend Blaise Aguirre's book on BPD in Adolescence (2nd edition) that has recent research on the same topic.
It does seem like things have changed a lot in the last 20 years and there are improvements although research can take a while to trickle into the mainstream, and sometimes even clinical practitioners are behind.
We also have members here who have children (both teens and adults) whose BPD traits are in remission, and they can share their stories.
I remember listening to Gundersen, a leading expert on BPD, talk about how the DSM does not do a good job of defining severity of BPD, and that this would help shed some light on how to treat different kinds of BPD sufferers.
The key, too, is figuring out not only what treatment works, and how motivated the child is, but also what changes are made to create a more validating environment. That's us.
How is your daughter doing at the moment? Is she accepting her dual diagnoses?
