 The investigators chose to study the efficacy of a mindfulness-based intervention to reduce anxiety in this population because this type of intervention has been shown to reduce anxiety in a number of populations, including in older adults. Further, accumulating evidence indicates that intensive mindfulness training effectively down-regulates a number of other adverse psychological and biological risk factors for AD, such as stress, depression, insomnia, feelings of loneliness and social exclusion, and cardiovascular risk factors. These findings are relevant to AD because approximately a third of AD cases worldwide might be attributable to potentially modifiable risk factors. In spite of the increased use of mindfulness-based interventions to treat clinical symptoms, these trials often suffer from the lack of an adequate comparison condition and lack of follow up to know whether initial benefits are maintained.
