Study discover emotion-focused therapy for bipolar disorder, Health News, ET HealthWorld
Washington: A therapeutic tool focused on emotional awareness that increased activation and connectivity of an emotion-regulating centre in the brain has been discovered by researchers. The therapy may be useful in the long-term treatment and prevention of relapse in bipolar disorder (BD).The findings of the study were published in Biological Psychiatry: Cognitive Neuroscience and NeuroimagingPatients with bipolar disorder have alternating extreme mood states characterised by mania, depression, and impaired social functioning. The complex mechanisms of BD make it difficult to treat, frequently necessitating a cocktail of medications and behavioural interventions that can take years for the provider and patient to successfully personalise.Led by Kristina Meyer, PhD, and Catherine Hindi Attar, PhD, at Charite - Universitatsmedizin Berlin, in Berlin, Germany, the researchers investigated the impact of two psychotherapeutic interventions on BD symptoms and on amygdala activation and connectivity with other emotion-related brain regions using functional magnetic resonance imaging (fMRI).The amygdala, a pair of small, bilateral regions in the brain's limbic system, helps regulate emotion and detect salient stimuli. Research has shown that BD patients (outside of a manic episode) display altered activation and functional connectivity of the amygdala.In one intervention, 28 patients underwent an emotion-focused therapy where they were guided to perceive and label their emotions without avoidance or suppression. The second intervention, delivered to 31 participants, was a specific cognitive-behavioral therapy that focused on practicing social interventions.The researchers recorded the patients' symptoms using a longitudinal evaluation interview for 24 weeks pre-treatment as well as for six months throughout treatment, six months post-treatment, and between six and 12 months post-treatment. The evaluation produced separate weekly measures of mania and depression on a 1 to 6 scale ranging from no symptoms (1) to psychotic symptoms or severe functioning impairments (6). Seventeen participants from each treatment group underwent fMRI while performing an emotional face-matching task, as did 32 healthy control subjects."In line with our expectations, the patients participating in the emotion-focused therapy showed an increased activation and connectivity of the amygdala post-intervention compared to the patients receiving the cognitive-behavioral intervention, which may reflect improved emotion processing and increased tolerance towards negative emotions," said Dr. Meyer. In contrast, the patients of the cognitive-behavioral intervention demonstrated increased activation of brain regions related to social function but not altered amygdala activity."The results of this study suggest that different psychotherapeutic approaches unfold their beneficial effects by different neural routes," added senior author Felix Bermpohl, PhD, Charite - Universitatsmedizin Berlin.
