简要总结
The goal of this study is to examine the impact of mind-body interventions in enhancing behavioral and neural correlates of attentional control in older adults. Participants will be randomized to either a 8-week mindfulness meditation group or a 8-week lifestyle education group. Additional booster sessions, spanning the course of a year, will be offered to participants in both groups. Participants will complete pre- and post-assessments of neurocognitive and emotional functioning, and will be assessed for maintained benefits 12-months post-intervention.
详细描述
Mind-body interventions are increasingly being examined for their potential to improve cognitive function, enhance emotion regulation, reduce stress and related inflammatory markers, and alter the neural circuitry supporting cognitive and emotional functioning. The primary goal of this study is to examine changes in attentional control resulting from engaging in mind-body interventions with additional booster sessions over the course of a year. Within this goal, the behavioral and neural mechanisms of change in attentional control will be investigated and the transfer of benefits to performance on measures of everyday cognition and emotion regulation will be assessed. Our main hypothesis is that eight weeks of mindfulness training will increase attentional control performance in the elderly, partially through mindfulness-induced reductions in mind-wandering and changes in the functional architecture of the brain. Up to 200 older adults (ages 65-85) will be enrolled for the study. Of these, 151 older adults meeting eligibility criteria will be randomized to either an eight-week MBSR (mindfulness based stress reduction) program or a lifestyle education group. Participants will attend weekly mindfulness training or lifestyle education sessions and will be asked to complete homework assignments administered via a mobile/web-based application designed by the laboratory. All participants will also be invited to participate in four booster sessions over the course of 12 months following the intervention with continued access to the mobile application content. Behavioral metrics of cognitive function and inflammatory markers will be collected before and after the eight-week intervention as well as at 6-months and 12-month follow-up assessments. Neural metrics of cognitive functioning will be collected before and after the eight-week intervention as well as at 12-month follow-up assessments.

结局指标
主要结局
Change in attentional control on tasks of sustained attention
时间窗: Baseline, 2 months, 8 months, 14 months
Participants will complete computerized measures of Continuous Performance Test and Go/No-Go Task to assess sustained attention. Detectability (d') measures will be calculated to assess the effects of mind-body interventions on attentional control. Data collected at 8-months and 14-month will be used to determine maintenance effects.
