Study type | Interventional |
The objective of this study is to determine whether regular Mindful Awareness Program (MAP)
may reverse cognitive impairment and/or prevent further cognitive decline among older
adults. 60 elderly with mild cognitive impairment (MCI) were randomized to participate in
either the MAP or the Health Education Program (HEP). Sessions will be conducted weekly for
12 weeks, and monthly for 6 months. Participants would be assessed at 3 time-points: at the
start, at 3-months and at 9-months.
It was hypothesized that as compared to HEP participants, MAP participants will (1) have
improved functional connectivity, (2) have a decreased risk in cognitive decline and (3)
report higher psychological well-being.
