Meditation's impact on default mode network and hippocampus in mild cognitive impairment: a pilot study.
Neuroscience Letters November 27, 2013 Rebecca Erwin Wells, Gloria Y Yeh, Catherine E. Kerr et al.
In adults with mild cognitive impairment (MCI), an 8-week Mindfulness Based Stress Reduction (MBSR) program increased functional connectivity between the posterior cingulate cortex and both the medial prefrontal cortex and hippocampus, and showed trends of reduced hippocampal atrophy compared to usual care. These preliminary results suggest MBSR may positively affect brain regions linked to MCI and Alzheimer's disease, though larger studies with longer follow-up are needed.
