Biobehaviorale Mechanismen reaktiver Aggression bei der Borderline Persönlichkeitsstörung: Validierung und pharmakologische Modulation
Zusammenfassung der Projektergebnisse
In this project, we have achieved to assess behavioral correlates for identified mechanisms of reactive aggression, namely, hypersensitivity for interpersonal threat, approach rather than avoidance of interpersonal threat, emotional contagion, deficient cognitive theory of mind, and reduced anger regulation, as well as behavioral, self-report, and neural correlates of reactive aggression in a large, heterogeneous sample of patients with BPD and healthy volunteers. First results indicate elevated self-reported aggression, a rigid pattern of interpersonal behavior in the aggression paradigm, and altered prefrontal-limbic activation patterns during provocation in patients with BPD. In the second part of the project, we were able to perform a double-blind placebo-controlled challenge study in which emotion classification and approach-avoidance tendencies of patients with BPD and healthy volunteers were measured after oxytocin or placebo administration. EEG was continuously measured during the emotion classification task as well as during a brief resting state period. First results indicate a normalization of approach-avoidance tendencies by oxytocin in patients with BPD. Oxytocin however did not affect reduced heart-beat evoked potentials, a marker for the cortical representation of interoceptive signals in BPD. Data processing is still ongoing.
