What is Rapid Eye Movement Sleep Mediates Age-related Decline in Prospective Memory Consolidation about?

## Study objectives: Prospective memory, or remembering to execute future intentions, accounts for half of everyday forgetting in older adults. sleep intervals benefit prospective memory consolidation in young adults, but it is unknown whether age-related changes in slow wave activity, sleep spindles, and/or rapid eye movement (rem) sleep mediate hypothesized effects of aging on prospective memory consolidation. ## Methods: After an adaptation night, 76 adults aged 18-84 completed two experimental nights of in-laboratory polysomnography recording. in the evening, participants encoded and practiced a prospective memory task and were tested the next morning. on a counterbalanced night, they encoded and practiced a control task, and were tested the following morning. ## Results: Increasing age predicted worse prospective memory consolidation (r = -.34), even when controlling for encoding, speed, and control-task performance (all ps < .05). frontal delta power, slow oscillations, and spindle density were not related to prospective memory consolidation. rem sleep duration, however, explained significant variance in prospective memory consolidation when controlling for age (∆r2 = .10). b
