Effects of an 18-month meditation training on dynamic functional connectivity states in older adults: Secondary analyses from the Age-Well randomized controlled trial

An 18-month meditation training in healthy older adults altered resting-state brain dynamics. Participants who meditated showed more frequent transitions between different brain connectivity states and spent less time in a weakly connected state and more time in a strongly connected state, patterns associated with lower and higher dementia risk, respectively. However, only the increase in transitions was significantly different from a non-native language training group. The small effect sizes and lack of group differences for time spent in states limit the conclusions.
