Brief summary: Emotion-related brain activation is made visible for patients via neurofeedback with the aim to improve discriminability of emotional arousal and emotion regulation. With functional magnetic resonance imaging (fMRI), information of current brain activation is imaged and fed back to the patient via a visual display. Patients with borderline personality disorder (BPD) usually hyper-activate brain regions associated with emotion. In this study, BPD patients will be provided with neurofeedback from the amygdala, which is crucial for the processing of emotions. The aim of the study is to observe, whether amygdala-neurofeedback would help BPD patients to improve emotion regulation. Compared to a control condition, improved brain self-regulation and emotion regulation is expected with three neurofeedback training sessions.

Detailed description: Patients with BPD show increased emotional reactivity, slow return to baseline, and severe emotion dysregulation symptoms. On the neural level, BPD patients hyper-activate the amygdala and hypo-activate the prefrontal cortex in response to emotional stimuli. The prefrontal cortex and the amygdala are crucial nodes of the brain's emotion regulation network and thus it is assumed, that dysregulation within this network is key to BPD symptoms. Psychotherapy treatments specialized for BPD teach patients to monitor emotional arousal and to develop emotion regulation skills. However in the long run and despite of important therapeutic advances, the majority of BPD patients keep reporting significant impairments in functioning after psychotherapy.

To explore new types of therapy in BPD, the investigators have applied real-time fMRI neurofeedback, where patients are provided with their brain activation via a visual display. In previous work they found that BPD patients and healthy participants can down-regulate amygdala activation with real-time fMRI neurofeedback, and increase connectivity between the amygdala and the prefrontal cortex. Yet, we do not yet fully understand the potential effects of amygdala neurofeedback on emotion.

BPD patients (n=25) participate in a three-session fMRI neurofeedback training with 2-7 days between sessions (within 2 weeks). The effect of the training will be measured before and after training. Primarily, the investigators expect an improvement in emotion regulation, secondarily, reductions in BPD symptoms are expected.

Hypotheses:

With fMRI neurofeedback, BPD patients improve significantly in self-report and psychophysiological measures of emotion regulation with fMRI neurofeedback training. BPD patients show significantly reduced symptom severity in self-report measures with neurofeedback training.
