Abstract
Individuals with borderline personality disorder (BPD) commonly display deficits in emotion regulation, but findings in the area of social cognitive (e.g., theory of mind, ToM) capacities have been heterogeneous. The aims of the current study were to investigate differences between patients with BPD and controls in functional connectivity (1) between the emotion and ToM network and (2) in the default mode network (DMN). Functional magnetic resonance imaging was used to investigate 19 healthy controls and 17 patients with BPD at rest and during ToM processing. Functional coupling was analysed. Significantly decreased functional connectivity was found for patients compared with controls between anterior cingulate cortex and three brain areas involved in ToM processes: the left superior temporal lobe, right supramarginal/inferior parietal lobes, and right middle cingulate cortex. Increased functional connectivity was found in patients compared with controls between the precuneus as the DMN seed and the left inferior frontal lobe, left precentral/middle frontal, and left middle occipital/superior parietal lobes during rest. Reduced functional coupling between the emotional and the ToM network during ToM processing is in line with emotion-regulation dysfunctions in BPD. The increased connectivity between precuneus and frontal regions during rest might be related to extensive processing of internal thoughts and self-referential information in BPD.

Abstract
Borderline Personality Disorder (BPD) has been defined as a personality disorder in all editions of DSM since 1980; namely, DSM III through V. The criteria are a mixture of symptoms and traits; the etiology, a heterogeneous array of genetic, constitutional, and environmental factors. Until recently the diagnosis relied on clinical descriptions. In the last two decades, neurophysiological data, including MRI and fMRI, have established correlates in various brain regions, particularly those involving the frontal lobes and various limbic structures, that show promise of providing a more substantial basis for diagnosis-relying primarily on (internal) brain changes, rather than on (external) clinical observation. Some of the changes in BPD consist of decreased volume in the orbitofrontal and dorsolateral prefrontal cortices and smaller volume in both the amygdala and hippocampus, though with heightened reactivity in the amygdala. Similar abnormalities have been noted in bipolar disorders (BDs) and in ADHD, both of which often accompany BPD and share certain clinical features. Persons with strong genetic predisposition to BDs can develop BPD even in the absence of adverse environmental factors; those with extreme adverse environmental factors (chiefly, early sexual molestation) can develop BPD in the absence of bipolar vulnerability. In some BPD patients, both sets of factors are present. As ideal treatment depends on careful analysis of these factors, neurophysiological testing may permit both more rational, brain-based diagnostic decisions and more appropriate therapeutic strategies.

Abstract
Borderline personality disorder (BPD) has been recognized as heterogeneous, etiologically, stemming from many combinations of genetic and environmental factors BPD never occurs alone: it is always accompanied by traits of other personality disorders and by various symptom-conditions, especially mood disorders. The controversy about linkage between BPD and bipolar disorder could not be resolved when the debate relied only on clinical description. Some twin-studies suggested modest overlap between BPD and bipolar disorder. Current neuroimaging research points to similarities in brain changes among several conditions characterized by emotional over-reactivity to stress: bipolar disorder, certain cases of BPD and attention-deficit hyperactivity (ADHD). These include alterations in the limbic system (e.g., amygdala and hippocampus) and neocortex (especially the prefrontal cortex). An important subset of BPD exists in which brain changes are essentially identical with those of bipolar disorder. Relevant brain-change findings and treatment implications are summarized in this article.

Abstract
Borderline Personality Disorder (BPD) has been often described recently as a condition characterized by emotional dysregulation. Several other conditions share this attribute; namely, Bipolar Disorder (BD), Attention-Deficit/Hyperactivity Disorder (ADHD), Intermittent Explosive Disorder (IED), and Major Depressive Disorder (MDD). The dysregulation is not always in the same direction: BPD, BD, ADHD, and IED, for example, show over-reactivity or "hyperactivity" of emotional responses, whereas patients with MDD show emotional sluggishness and underactivity. At the clinical/descriptive level the "over-reactive" conditions appear separate and distinct. BPD constitutes a large domain within the psychopathological arena, appearing to contain within it a variety of etiologically diverse subtypes. Among the latter is a type of BPD linked closely with Bipolar Disorder; family studies of either condition show an overrepresentation of both: BPD patients with bipolar relatives; Bipolar patients with BPD relatives. A significant percentage of children with ADHD go on to develop either BPD or BD as they approach adulthood. If one shifts the spotlight to neurophysiology, as captured by MRI studies, however, it emerges that an important subtype of BPD, and also BD, ADHD, and IED-share common features of abnormalities and peculiarities in the limbic system and in the cortex, especially the prefrontal cortex. Deeper subcortical regions such as the periaqueductal gray may also be implicated in strong emotional reactions. The diversity of clinical "over-reactive" conditions appear to harken back to a kind of unity at the brain-change level. There are therapeutic implications here, such as the advisability of mood stabilizers in many cases of BPD, not just for Bipolar Disorder.

Abstract
Borderline personality disorder is a serious mental health problem for which one of its main characteristics is significant difficulties in relationships with others. These relational problems have the unfortunate consequence of fostering negative attitudes among mental health professionals and contributing to the stigmatization of people suffering from this disorder. In this article, the author emphasizes the importance of taking into account the parameter of the therapeutic frame within which the feeling of facing a stalemate in the treatment of borderline personality disorder patients occurs. Six general strategies are presented that enable the therapist to limit or hinder the risk of stalemate in treatment. This article then presents the commonalities between treatments teams that tend to feel comfortable and efficacious in their management of borderline personality disorder patients. Finally, a case history is used to illustrate how some stalemates can in fact be seen as opportunities for growth for both the patient and the therapist. In order to avoid the vicious circle of negative interactions with patients already hypersensitive to inconsistencies and rejection, the author concludes by insisting on the necessity that more mental health professional have access to training programs and workshops specifically addressing how to better manage and treat people with BPD.
