Bipolar II vs. Borderline

I didn't really think there still was a big disagreement about these disorders being distinct in nature. But I guess those voices pop up on a regular basis. This study shows, however, that bipolar II-depression patients are more likely to have close relatives with bipolar disorder than patients with a combination of major depressive disorder and borderline personality disorder (MDD-BPD). MDD-BPD patients also had a higher frequency of co-morbid axis-1 disorders than the the bipolar II-depression patients, most significantly post-traumatic stress disorder. Ratings of anger, anxiety, paranoid ideation and somatization were also significantly higher in the MDD-BPD group and in addition to that their over all functioning was lower. This certainly is evidence supporting the disorders to be different in nature.
