Socialand and emotional emotional processing processing in Social in Borderline Personality Disorder Borderline Personality Disorder James Cusack Research Fellow in Psychiatry University of Aberdeen www.abdn.ac.uk My aims • I would like to get your views on my research plans. • To understand social and emotional processing in Borderline Personality Disorder. • To understand the effect of psychotherapy on Borderline Personality Disorder. www.abdn.ac.uk Background Theory of mind • The ability to understand the intentions, desires, emotions and beliefs of another individual. • The Sally-Anne task www.abdn.ac.uk The brain Images from www.wellcomecollection.org www.abdn.ac.uk The visual cortex Images from www.wellcomecollection.org www.abdn.ac.uk A face Images from Nature Neuroscience, Vuilleumeier et al. (2003) www.abdn.ac.uk Processing of faces Images from www.wellcomecollection.org www.abdn.ac.uk Emotional arousal Images from www.wellcomecollection.org www.abdn.ac.uk The amygdala • Rapid response to emotional stimuli • Emotional arousal • Emotional learning Image From Frontiers in brain imaging methods, Hanson et al. (2012) www.abdn.ac.uk A face Image from Nature Neuroscience, Vuilleumeier et al. (2003) www.abdn.ac.uk An emotional face Image from Nature Neuroscience, Vuilleumeier et al. (2003) www.abdn.ac.uk Which one excites the amygdala? Image from Nature Neuroscience, Vuilleumeier et al. (2003) www.abdn.ac.uk Introducing BPD • Characterised by problems with emotional regulation • We know that forming relationships is something which can present challenges • Complex interaction between environmental and genetic factors • The amygdala is important for emotional regulation www.abdn.ac.uk Social cognition in BPD • Increased sensitivity to facial expression in BPD? • Yes Image from Nature Neuroscience, Vuilleumeier et al. (2003) www.abdn.ac.uk The amygdala in BPD • Structurally smaller • “Hypersensitive” • “Highly vigilant” Image From Frontiers in brain imaging methods, Hanson et al. (2012) www.abdn.ac.uk Theory of mind in BPD Scores • Performance on two tasks were studied in people with BPD. Image from Psychiatry Research, Harai et al. (2010) www.abdn.ac.uk Mirror Neurons • Neurons which fire during the performance and observation of the same sensory action. Image from Neuroscience and biobehavioral reviews Molenberghs et al. (2012) www.abdn.ac.uk Mirroring and BPD • Social development • Simulation • Imitation www.abdn.ac.uk Research questions • How well do people with BPD imitate (copy) the facial expression of others? • Intensity of simulation process as a consequence of increased affective sensitivity? • Would this lead to better empathy? • Or is imitation something which presents challenges? • How does imitation ability relate to other skills in BPD? www.abdn.ac.uk Social cognition 1. Attend to salient emotion 2. Understand perspective of individual, 3. Regulation of emotion www.abdn.ac.uk How does emotion regulation work? • They amygdala and the prefrontal cortex Dorsomedial prefrontal cortex Amygdala Ventromedial prefrontal cortex www.abdn.ac.uk Emotional regulation in BPD • Cortico-limbic disconnection model • Sensitivity to facial expression • Current evidence • A risk factor? • Cognitive reappraisal www.abdn.ac.uk Performing theory of mind 1. Attend to salient emotion 2. Understand perspective of individual 3. Regulation of emotion www.abdn.ac.uk Research questions • How well do people with BPD imitate (copy) the facial expression of others? • Intensity of simulation process as a consequence of increased affective sensitivity? • Would this lead to better empathy? • Or is imitation something which presents challenges? • How does imitation ability relate to other skills in BPD? • How do any difficulties with regulation relate to imitation? www.abdn.ac.uk Mentalisation-based therapy • Effective in the treatment of BPD • Aims to help individual understand the mental states of others and themselves. • How does this therapy work? www.abdn.ac.uk Research questions • How well do people with BPD imitate (copy) the facial expression of others? • Does psychotherapy have an effect on the ability to imitate in BPD? • What mechanisms does psychotherapy tap in to? • Does psychotherapy improve imitative ability? • What about emotional regulation? www.abdn.ac.uk Answering our research questions Aim: to develop a task to detect subtle deficits of facial imitation • We need facial expressions that vary in a dimensional and meaningful way • Morphing www.abdn.ac.uk Blending Darwin’s six emotions www.abdn.ac.uk Blending contrasting emotions in 3D ‘Face-Space’ www.abdn.ac.uk Facial imitation task? www.abdn.ac.uk Data analysis? • Manual rating www.abdn.ac.uk Manual rating www.abdn.ac.uk Data analysis? • Manual rating • Image processing and computer vision algorithms www.abdn.ac.uk Facial imitation task? www.abdn.ac.uk Methodological principles • Quantitative measurements • Reliably measure threshold of individual performance, not just group average • Multiple comparison groups www.abdn.ac.uk The plan • We would like to recruit people with BPD and people who do not have BPD. • We will compare performance on this task before and after psychotherapy. • Other tasks. www.abdn.ac.uk Outcome of this study • Further understanding of mechanisms which underpin BPD and psychotherapy • What parts of the brain are different in BPD? • How can we help understand what leads to the difficulties experienced by people with BPD? • Provide an explanation for BPD. • How can we improve interventions? • How can we aid identification of symptoms to ensure rapid treatment? www.abdn.ac.uk Future research questions • Psychophysiology • Brain imaging • Automated measures of face to face interaction – outcome measures www.abdn.ac.uk Thanks • Thank you to you all for your time • Thank you to the psychiatry group for their comments www.abdn.ac.uk j.cusack@abdn.ac.uk James Cusack Research Fellow in Psychiatry University of Aberdeen
