Meditation's impact on default mode network and hippocampus in mild cognitive impairment: a pilot study.

Those with high baseline stress levels are more likely to develop mild cognitive impairment (MCI) and Alzheimer's Disease (AD). While meditation may reduce stress and alter the hippocampus and default mode network (DMN), little is known about its impact in these populations. Our objective was to conduct a "proof of concept" trial to determine whether Mindfulness Based Stress Reduction (MBSR) would improve DMN connectivity and reduce hippocampal atrophy among adults with MCI. 14 adults with MCI were randomized to MBSR vs. usual care and underwent resting state fMRI at baseline and follow-up. Seed based functional connectivity was applied using posterior cingulate cortex as seed. Brain morphometry analyses were performed using FreeSurfer. The results showed that after the intervention, MBSR participants had increased functional connectivity between the posterior cingulate cortex and bilateral medial prefrontal cortex and left hippocampus compared to controls. In addition, MBSR participants had trends of less bilateral hippocampal volume atrophy than control participants. These preliminary results indicate that in adults with MCI, MBSR may have a positive impact on the regions of the brain most related to MCI and AD. Further research with larger sample sizes and longer-follow-up are needed to further investigate the results from this pilot study.

Teaching Tai Chi with mindfulness-based stress reduction to middle school children in the inner city: a review of the literature and approaches.

Tai Chi (TC) is the focus of a growing body of literature both qualitative and empirical. Yet there is a paucity of literature on teaching TC to either adolescents or children ages 10-13 presumably because of the level of attention and concentration TC requires. In the pediatric setting, TC appears best combined with other practice activities like mindfulness-based stress reduction (MBSR) that complement the practice of TC, sustain interest and synergistically enhance the benefits TC has been shown to produce in older populations. The literature on the effects of (MBSR) practices with children and teens are also limited. However, the corpus of TC studies suggests significant benefits could be transgenerational if presented in novel ways and taught in developmentally appropriate approaches to children. This chapter explores combining MBSR exercises with TC as one practice that can potentially accomplish this synergy. The chapter includes recommendations for a course design based on two projects created by the author integrating TC and MBSR for ages 11-14 in the inner city of Boston, Mass., USA.

Tai Chi and mindfulness-based stress reduction in a Boston Public Middle School.

This article provides a description of a clinical project that used combined Tai Chi and mindfulness-based stress reduction as an educational program. The 5-week program demonstrated that sustained interest in this material in middle school-aged boys and girls is possible. Statements the boys and girls made in the process suggested that they experienced well-being, calmness, relaxation, improved sleep, less reactivity, increased self-care, self-awareness, and a sense of interconnection or interdependence with nature. The curriculum is described in detail for nurses, teachers, and counselors who want to replicate this type of instruction for adolescent children. This project infers that Tai Chi and mindfulness-based stress reduction may be transformational tools that can be used in educational programs appropriate for middle school-aged children. Recommendations are made for further study in schools and other pediatric settings.
