The meds are called antipsychotics, but that says nothing about what they do...partial d2 antagonism, variable d1-6 actions, variable serotonin actions, NE variability, all different by the med and the dose. It seems that the variable nature of these meds help BPD. The older antipsychotics helped as well and they were mainly just d2 antgonists. Perhaps that is the key, but i doubt it......
