Mindfulness-based cognitive therapy (MBCT) alters brain network dynamics during depressive rumination in people with recurrent depression. In a randomized trial, 27 patients received MBCT plus treatment as usual, while 21 received treatment as usual alone. Using fMRI, researchers analyzed brain substates during an induced rumination state before and after treatment. MBCT changed the probability of a specific 'Salience-somatomotor' brain substate occurring during rumination, compared to the control group. These dynamic network changes were linked to reduced depressive symptoms after treatment and at three months follow-up, suggesting a candidate brain mechanism for how mindfulness training improves clinical outcomes.

In people with major depressive disorder, mindfulness-based cognitive therapy (MBCT) plus treatment as usual, compared to treatment as usual alone, alters whole-brain dynamics in ways that may reduce rumination. Using a novel method called complex harmonics decomposition on fMRI data from 80 patients, the study identified low-dimensional spatiotemporal manifolds that capture both local and long-range brain interactions. After MBCT, during rumination, brain regions involved in bodily and interoceptive processing became more consistently integrated across these manifolds. The latent configurations shifted with clinical and behavioral improvements, and the brain showed greater flexibility within the reduced space. These changes may reflect reduced 'stickiness' of ruminative thinking patterns following mindfulness training.

In people with major depressive disorder, mindfulness-based cognitive therapy (MBCT) plus treatment as usual, compared to treatment as usual alone, increased the hierarchical organization of brain activity during rumination but not at rest. Greater hierarchy—meaning more directional information flow and less recurrent looping—was linked to improvements in clinical and behavioral outcomes. This shift away from self-reinforcing negative mental loops toward more differentiated cognitive and bodily cycles may help explain how MBCT interrupts ruminative thought patterns. Hierarchical brain dynamics could serve as a treatment-sensitive marker and potential mechanism of therapeutic change in MBCT for depression.

Mindfulness-based cognitive therapy (MBCT) alters brain network dynamics during depressive rumination in people with recurrent depression. In a randomized controlled trial with 48 participants, those who received MBCT plus treatment as usual showed changes in the occurrence frequency of a 'salience-somatomotor' brain state during rumination compared to those receiving treatment as usual alone. These neural changes were linked to reduced rumination after treatment and fewer depressive symptoms three months later. The findings suggest that MBCT may work by modifying how the brain's somatosensory and salience networks interact during rumination, offering clues about the brain mechanisms underlying treatment response.
