Charakterisierung der neuronalen Antwort und Entwicklung eines Neurofeedback-Trainings bei der Borderline Persönlichkeitsstörung
Zusammenfassung der Projektergebnisse
This project established neural training for down-regulation of amygdala activation, with the aim to contribute an effective brain-derived treatment of dysregulated emotion. Brain activations become visible with live-feedback from neuroimaging, named neurofeedback. Neurofeedback empowers patients to self-regulate the amygdala, which is a neural center of emotion processing. A requirement to practice down-regulation is sustained activation of the target brain region. It was demonstrated in this project that the amygdala shows the critical sustained response when persons are exposed to negative emotional scenes for eighteen seconds. The literature suggests that the amygdala response is inflated in patients with Borderline Personality Disorder (BPD). Amygdala hyper-responding is supposed to underlie emotional hyper-reactivity. It was shown that fMRI neurofeedback training is feasible, is well accepted by patients and alters connectivity in critical neural networks of emotion processing and regulation. Affective instability, which is hallmark symptom of BPD, was reduced and emotion regulation improved. Changes were demonstrated in the brain, in psychophysiological measures and in behavior, including ecological momentary assessment. Future studies with placebo control are needed to confirm that the clinical improvements demonstrated in this project are due to amygdala modulation.
