title: Does Borderline Personality Disorder Manifest Itself Differently in Patients With Bipolar Disorder and Major Depressive Disorder?
abstract: Perugi and colleagues (2013) recently reported that some features of borderline personality disorder (BPD) significantly predicted a diagnosis of bipolar disorder among depressed patients. They interpreted these findings as indicating that some BPD criteria are nonspecific and are indicators of bipolar disorder rather than BPD, whereas other criteria are more specific to BPD. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, the authors tested the hypothesis that BPD presents itself differently in psychiatric outpatients diagnosed with bipolar disorder or major depressive disorder. The authors found that the patients with bipolar disorder were significantly more likely to report impulsive behavior and transient dissociation. No criterion was significantly more common in the BPD patients with MDD. The authors therefore do not consider the BPD criteria to be nonspecific with regard to the distinction between BPD and bipolar disorder.
