Functional connectivity of pain-mediated affect regulation in Borderline Personality Disorder.

ABSTRACT: Affective instability and self-injurious behavior are important features of Borderline Personality Disorder. Whereas affective instability may be caused by a pattern of limbic hyperreactivity paired with dysfunctional prefrontal regulation mechanisms, painful stimulation was found to reduce affective arousal at the neural level, possibly underlying the soothing effect of pain in BPD.We used psychophysiological interactions to analyze functional connectivity of (para-) limbic brain structures (i.e. amygdala, insula, anterior cingulate cortex) in Borderline Personality Disorder in response to painful stimulation. Therefore, we re-analyzed a dataset from 20 patients with Borderline Personality Disorder and 23 healthy controls who took part in an fMRI-task inducing negative (versus neutral) affect and subsequently applying heat pain (versus warmth perception).Results suggest an enhanced negative coupling between limbic as well as paralimbic regions and prefrontal regions, specifically with the medial and dorsolateral prefrontal cortex, when patients experienced pain in addition to emotional arousing pictures. When neutral pictures were combined with painful heat sensation, we found positive connectivity in Borderline Personality Disorder between (para-)limbic brain areas and parts of the basal ganglia (lentiform nucleus, putamen), as well areas involved in self-referential processing (precuneus and posterior cingulate).We found further evidence for alterations in the emotion regulation process in Borderline Personality Disorder, in the way that pain improves the inhibition of limbic activity by prefrontal areas. This study provides new insights in pain processing in BPD, including enhanced coupling of limbic structures and basal ganglia.

Project description:Recent neuroimaging studies have associated activity in the default mode network (DMN) with self-referential and pain processing, both of which are altered in borderline personality disorder (BPD). In patients with BPD, antinociception has been linked to altered activity in brain regions involved in the cognitive and affective evaluation of pain. Findings in healthy subjects indicate that painful stimulation leads to blood oxygenation level-dependent signal decreases and changes in the functional architecture of the DMN.To connect the previously separate research areas of DMN connectivity and altered pain perception in BPD and to explore DMN connectivity during pain processing in patients with BPD.Case-control study.University hospital.Twenty-five women with BPD, including 23 (92%) with a history of self-harm, and 22 age-matched control subjects.Psychophysical assessment and functional magnetic resonance imaging during painful heat vs neutral temperature stimulation.Connectivity of DMN as assessed via independent component analysis and psychophysiological interaction analysis.Compared with control subjects, patients with BPD showed less integration of the left retrosplenial cortex and left superior frontal gyrus into the DMN. Higher BPD symptom severity and trait dissociation were associated with an attenuated signal decrease of the DMN in response to painful stimulation. During pain vs neutral, patients with BPD exhibited less posterior cingulate cortex seed region connectivity with the left dorsolateral prefrontal cortex.Patients with BPD showed significant alterations in DMN connectivity, with differences in spatial integrity and temporal characteristics. These alterations may reflect a different cognitive and affective appraisal of pain as less self-relevant and aversive as well as a deficiency in the switching between baseline and task-related processing. This deficiency may be related to everyday difficulties of patients with BPD in regulating their emotions, focusing mindfully on 1 task at a time, and efficiently shifting their attention from one task to another.

Project description:Personality disorders (PDs) are highly prevalent in patients receiving psychiatric services, and are associated with significant personal and social costs. Over the past two decades, an increasing number of treatment studies have documented the effectiveness of treatment for patients with PDs, especially when it comes to reduction of symptom distress, risk taking behavior, self-harm, or suicide attempts. However, less is known about the more complex aims of improving the personality structure itself, such as identity- and interpersonal disturbances. Emotional dysfunction is closely associated with PD pathology. The present study investigated changes in affect consciousness (AC) in patients with avoidant or borderline PD, and how these changes were associated with clinical status after 3 years of follow-up. The study included 52 individuals; 79 percent were females, and mean age was 30 years. The evaluations included the Affect Consciousness Interview, Symptom Checklist-90-R, Circumplex of Interpersonal Problems, the Index of Self-Esteem, and three domains (Identity Integration, Relational Capacities, and Self-Control) of the Severity Indices of Personality Problems (SIPP-118). There was a significant increase in the Global AC and AC scores for most of the specific affects from baseline to follow-up. As the present study did not include a control group, it cannot be concluded that changes in AC are effects of psychotherapy, and the possibility of age-related maturation processes cannot be excluded. The change in Global AC contributed significantly to explained variance in the follow-up levels of Circumplex of Interpersonal Problems, and the two SIPP-118 domains Relational Capacities and Identity Integration. Improved AC was not associated with change in the Self-Control domain or the Global Severity Index of Symptom Checklist-90-R. The results suggest that AC may be altered for patients with borderline and avoidant PDs, and this is the first study to report that improvement in AC contribute significantly to the variance in the self- and interpersonal domains of personality functioning.
