Metacognitive Training for Subjects with Bipolar Disorder: A Randomized Controlled Trial.

Introduction: Impairments in social cognition in bipolar disorder (BD) have been extensively described in the last decade but few treatment strategies have been studied to address this issue. This study presents findings from a randomized controlled trial (RCT) investigating the efficacy of metacognitive training for bipolar disorder (MCT-BD) compared to Treatment as Usual (TAU) among individuals with BD in remission. The aim was to determine whether MCT-BD could improve social cognition and overall functioning in this population.

Galanin subtype 1 and subtype 2 receptors mediate opposite anxiety-like effects in the rat dorsal raphe nucleus.

About 40% of the dorsal raphe nucleus (DRN) neurons co-express serotonin (5-HT) and galanin. Serotonergic pathways from the DRN to the amygdala facilitate learned anxiety, while those from the DRN to the dorsal periaqueductal grey matter (DPAG) impair innate anxiety. Previously, we showed that galanin infusion in the DRN of rats induces anxiolytic effect by impairing inhibitory avoidance without changing escape behaviour in the elevated T-maze (ETM).
