Just wanted to say, I am going to start DBT in a center specialized in BPD in September, and since the therapy's in the context of a scientific trial, they told me I will have to have an fMRI done twice a year (I think it was twice a year). They say the brain scan is supposed to look different before and after the therapy. I had never heard of this for personality disorders, either, but it doesn't make me feel bad, quite the contrary in fact. I don't have a history of trauma (although I have been sexually abused aged 17 by a date) so if the brain scan is different from a "normal person"'s one this is going to explain a lot. Plus, they claim DBT can actually change the way our mind and our brain work. This makes me feel a wee bit uncomfortable, that's true, but I am quite relieved by this idea.
