Mindfulness-based interventions reduce activation in the right dorsolateral prefrontal cortex when depressed patients view angry faces, a change linked to improved ability to decenter from negative thoughts, reduced brooding, and fewer depressive symptoms. In a randomized trial, patients with recurrent depression received either a two-week mindfulness-based intervention or psychoeducation and rest. After the mindfulness intervention, decreased right dlPFC activation correlated with greater decentering, less brooding, and lower symptom scores. The psychoeducation group showed decreased amygdala response to happy faces. The findings suggest mindfulness may help patients avoid elaborating or suppressing negative emotions, a potential mechanism for preventing mood escalation.
Major depressive disorder involves abnormal communication between large-scale brain networks. A randomized, active-controlled trial tested whether mindfulness-based therapy could alter resting-state functional connectivity in clinically depressed patients. A brief, clinically effective mindfulness intervention functionally decoupled top-down control regions from brain areas involved in sensory, affective, and attentional processing. These findings identify specific neural targets of mindfulness training, offering new insight into how this therapeutic approach works.
A brief mindfulness-based intervention (three individual sessions plus home practice) reduced depressive symptoms more than a control condition combining psycho-education and rest in 74 acutely depressed patients with chronic or recurrent depression. Only the mindfulness group showed increases in mindfulness and decreases in ruminative tendencies and cognitive reactivity. The findings suggest that targeted mindfulness training can help alleviate current symptoms and buffer maladaptive responses to negative mood in this population.
A brief mindfulness-based intervention (MBI) of three individual sessions plus regular home practice reduced depression symptoms more than a control condition with psycho-education and rest in 74 patients with chronic or recurrent depression. Only the MBI group showed increases in mindfulness and decreases in ruminative tendencies and cognitive reactivity. The results support a stress-buffering role for mindfulness and indicate that even short, targeted mindfulness training can alleviate symptoms in acutely depressed patients with a long-term history.
