“…self‐report recollection) of sleep quality. Previous comparisons of objective and subjective measures of sleep quality have shown that they are often discordant in older adults (DiNapoli et al, ; Landry, Best, & Liu‐Ambrose, ); thus, the degree to which PA is related to objective indices of sleep quality is unclear. Further, sleep quality and PA are often averaged over multiple days, which ignores day‐to‐day variation and limits the ability of the research to determine whether one behaviour influences the other from one day to the next (McGlinchey, Gershon, Eidelman, Kaplan, & Harvey, ).…”

Sleep quality and physical activity (PA) appear to be interrelated; thus, by promoting one behaviour, it may be possible to improve the other in older adults. Examination of the within-person day-to-day variation in PA and sleep quality could potentially elucidate the directionality of the association of these behaviours. We measured sleep quality (i.e. fragmentation, efficiency, duration and latency) and moderate-to-vigorous PA using the MotionWatch8© over 14 consecutive days and nights in community-dwelling adults (n = 152; age range 53-101 years). Multilevel modelling estimated within-subject autoregressive and cross-lagged effects and between-subject associations between PA and sleep quality. On days when individuals engaged in a high amount of PA on one day (relative to their averages), they were more likely to engage in a high amount of PA on the next day (estimate, 0.19; 95% CI, 0.14, 0.24). Nights in which individuals had a long sleep latency were followed by nights in which they also had a long sleep latency (estimate, 0.09; 95% CI, 0.03, 0.14). In contrast, nights in which individuals slept for a long period of time were followed by nights in which they slept relatively less than their averages (estimate, -0.09; 95% CI, -0.13, -0.04). When individuals engaged in a large amount of PA during the day, they tended to sleep longer that following night (estimate, 0.01; 95% CI, 0.001, 0.02). All other associations between PA and sleep quality were not significant. Increasing PA therefore might increase sleep duration in older adults.

“…On the other hand, 28.8% reported poor sleep quality but had good objective sleep efficiency. The correlation between objective sleep efficiency and perceived sleep quality in this sample was low (r = - 0.06; p = 0.64; DiNapoli et al, 2017). These results indicated a discrepancy between perceived and objective sleep, supporting using multiple sleep measures.…”

Sleep-wake disturbances have been associated with episodic memory loss, but past studies were limited by use of single measures of objective or perceived disturbances. Notably, cognitive reserve and depressive symptoms have been associated with sleep-wake disturbances and poorer episodic memory in older adults. The aims of this study were to determine the relationship between episodic memory and sleep-wake disturbances using objective and perceived measures in older adults and to examine cognitive reserve and depressive symptoms as moderators of this relationship. In this descriptive study, 62 healthy older adults (mean age: 69.9 years; 75.8% women) were recruited from the University of Michigan Clinical Research Program. Objective sleep-wake disturbances were measured by 7-day actigraphy and perceived sleep-wake disturbances by the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale. Episodic memory was measured by the Hopkins Verbal Learning Test-Revised. Analyses involved Pearson’s correlation coefficients and hierarchical multiple regression. Results showed that more objectively measured sleep disruption was associated with poorer episodic memory and more perceived daytime sleepiness was associated with better episodic memory. Cognitive reserve and depressive symptoms were not moderators of this relationship. In this study, the relationship between sleep-wake disturbances and episodic memory differed by type of measure, objective or perceived. Future studies are needed using multiple measures of episodic memory to further understand the sleep-wake disturbances and episodic memory relationship in a larger diverse sample of healthy older adults.

“…However, MMSE scores did not correlate with subjective-objective differences suggesting that the discrepancy was not related to cognitive functioning as assessed by the MMSE [ 40 ]. Another study in 59 older adults with cognitive impairment and depression used an extensive battery of cognitive tests (including MMSE, CDR, and other dementia-specific tests) and found that delayed memory, but not level of executive functioning, was associated with increased discrepancy between actigraphy and the Pittsburgh Sleep Quality Index [ 39 ]. However, there have been several other studies that showed no effect of cognition as measured by MMSE or the Montreal Cognitive Assessment [ 31 , 33 ].…”

Comparison of single-channel EEG, actigraphy, and sleep diary in cognitively normal and mildly impaired older adults

Study Objectives Multiple methods for monitoring sleep-wake activity have identified sleep disturbances as risk factors for Alzheimer disease (AD). In order to identify the level of agreement between different methods, we compared sleep parameters derived from single-channel EEG (scEEG), actigraphy, and sleep diaries in cognitively normal and mildly impaired older adults. Methods 293 participants were monitored at home for up to 6 nights with scEEG, actigraphy, and sleep diaries. Total sleep time (TST), sleep efficiency (SE), sleep onset latency (SOL), and wake after sleep onset (WASO) were calculated using each of these methods. In 109 of the 293 participants, the ratio of cerebrospinal fluid concentrations of phosphorylated tau (p-tau) and amyloid-β-42 (Aβ42) was used as a biomarker for AD pathology. Results Agreement was highest for TST across instruments, especially in cognitively normal older adults. Overall, scEEG and actigraphy appeared to have greater agreement for multiple sleep parameters than for scEEG and diary or actigraphy and diary. Levels of agreement between scEEG and actigraphy overall decreased in mildly impaired participants and those with biomarker evidence of AD pathology, especially for measurements of TST. Conclusions Caution should be exercised when comparing scEEG and actigraphy in individuals with mild cognitive impairment or with AD pathology. Sleep diaries may capture different aspects of sleep compared to scEEG and actigraphy. Additional studies comparing different methods of measuring sleep-wake activity in older adults are necessary to allow for comparison between studies using different methods.
