The interface between borderline personality disorder and bipolar spectrum disorders

Descriptive and Longitudinal Observations on the Relationship of Borderline Personality Disorder and Bipolar Disorder

“…This modest association is also supported by our finding that patients with other personality disorders with cooccurring bipolar disorder showed more new onsets of borderline personality disorder. Still, given the other results in our study and those of other investigators (7,32), the modest association that has been observed between borderline personality disorder and bipolar disorder is not yet conclusive. Clearly, the new onsets of bipolar disorder did not represent an evolution from borderline personality disorder psychopathology; rather, they most often followed stressful neurobiological or life changes.…”

“…It is also appealing because it encourages an optimistic view that patients with borderline personality disorder might benefit from the extensive research on bipolar disorder and that these patients might also prove to be responsive to mood stabilizing medications. Still, as reviewed elsewhere, only a modest body of methodologically sound research to date addresses the interface of borderline personality disorder and bipolar disorders, and of this research, very little supports the thesis of a spectrum relationship between the two disorders (7).…”

Can Research Confirm Psychopathological Subtypes and Relationship between Recurrent Mood Disorders and Personality Disorders?

“…This association has not been completely resolved as numerous studies have shown varying temporal associations (comorbidity) between recurrent affective disorders and personality disorders [2][3][4][5][6]. In psychiatry, the dimensional theory, which is used for assessments, considers personality disorders as clinical forms of recurrent affective disorders.…”

“…Recent studies [5,20] have evaluated that BPD is a personality disorder that shows higher percentage of comorbidity with type I and type II bipolar disorder (BD I and II) compared to the other disorders of axis II (19.4% vs. 7.4% respectively). Moreover, the emergence of "new episodes" of type I and II BD occurs more frequently in BPD compared to other personality disorders (OPD) with percentages reaching 8.2% vs. 3% respectively.…”

A Comparative Study of Executive Functions and Cognitive Emotion Regulation in Patients with Borderline Personality Disorder and Normal Individuals

“…Borderline personality disorder includes a cluster of signs and symptoms that can be determined by unstable behavior and impulsivity. Impulsivity is considered as the main and infrastructural core of this disorder (Lieb, Zanarini & Linehan and Bauhaus, 2004) and also as the basic aspect in the understanding of its pathology (Paris, 2006;Paris, Weinberg & Gunderson, 2007). Patients with borderline personality disorder (BPD) are located on the border between neurosis and psychosis and are marked with great emotion, mood, behavior and object relations instability.…”
