Long-term meditation practice is linked to structural changes in the brain. Magnetic resonance imaging of 20 experienced Insight meditation practitioners showed greater cortical thickness in regions involved in attention, interoception, and sensory processing, including the prefrontal cortex and right anterior insula, compared to matched controls. The difference in prefrontal thickness was most pronounced in older participants, suggesting meditation may counteract age-related cortical thinning. Thickness in two regions also correlated with meditation experience. These findings provide the first structural evidence that meditation practice can induce experience-dependent cortical plasticity.

Mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) modestly improve depressive symptoms, anxiety, stress, quality of life, and physical functioning across a range of chronic conditions. A systematic review and meta-analysis of 23 reviews covering 115 randomized controlled trials and 8,683 individuals found that, compared with waitlist or treatment as usual, these programs yielded small to moderate benefits: depressive symptoms (Cohen's d=0.37), anxiety (d=0.49), stress (d=0.51), quality of life (d=0.39), and physical functioning (d=0.27). The evidence supports their use as adjunct treatments for cancer, cardiovascular disease, chronic pain, depression, anxiety disorders, and prevention in healthy adults and children, though heterogeneity, possible publication bias, and limited long-term follow-up temper confidence.

Among 94 chronically stressed but otherwise healthy adults randomized to eight weeks of meditation, yoga, or stress education, only the meditation group showed a significant reduction in resting-state functional connectivity between the posterior cingulate cortex and the left hippocampus. Changes in this brain connectivity were correlated with improvements in perceived stress, allostatic load, and anti-inflammatory gene expression, suggesting that meditation's neural effects are closely linked to physical wellness biomarkers. No such changes occurred in the yoga or stress education groups, indicating this neurobiological mechanism may be unique to meditation training.
