Ives-Deliperi et al. [Journal of Affective Disorders] compared 16 bipolar patients before and after MBCT with a wait-list control of 7 bipolar patients and a cohort of 10 untreated healthy controls. Participants were assessed for emotional and cognitive symptoms and underwent fMRIs while performing mindfulness meditation. The patient cohort consisted of bipolar I and bipolar 2 patients with only minimal or sub-threshold symptomatology.
Prior to MBCT, the bipolar participants exhibited higher anxiety and stress, poorer working memory, and lower medial prefrontal cortical (PFC) activity than healthy controls. After MBCT, bipolar patients exhibited decreased anxiety and improved mindfulness (as measured by the FFMQ), working memory, spatial memory, verbal fluency, and emotional regulation compared with wait-list controls.
In addition, the MBCT group exhibited increased activity in the medial PFC and the right posterior cingulate cortex (PCC) compared with wait-list controls and increased left anterior cingulate cortical (ACC) activity compared with healthy controls. Increased medial PFC function correlated significantly (r= .61) with improved FFMQ scores. The findings demonstrate MBCT’s positive impact on the core symptoms of emotional dysregulation and executive dysfunction in bipolar disorder.
