Abstract Introduction The micro-architecture of NREM sleep displays a cyclic alternating pattern (CAP) comprising activation phases of slow high-amplitude waves (A1), fast low-amplitude brain activity rhythms (A3) or a mixture of both (A2). In this study, we investigated the relationship between CAP and subjective sleep quality parameters reported by community-dwelling older men from the Osteoporotic Fractures in Men Sleep Study. Methods CAP was scored in 2,811 overnight EEG recordings using a high performance automated CAP detection system. We quantified the ratio between CAP time and NREM sleep time (CAP rate), the number of A1-phases per hour of NREM sleep (A1 index), and the number of A2+A3-phases per hour of NREM sleep (A2+A3 index). Also, participants were asked to score the quality of their sleep on a Likert scale with five items from light to deep, from short to long, and from restless to restful. The relationship between CAP parameters and the subjective sleep quality measures was determined using ANCOVA with traditional sleep disturbance indices such as obstructive apnea-hypopnea index and arousal index as covariate. Results CAP rate decreased significantly with increasing quality of sleep for all three subjective measures (light vs. deep: 58.8±22.3% vs. 54.6±20.5%, p < 0.001; short vs. long: 58.4±21.4% vs. 55.1±20.5%, p < 0.001, restless vs. restful: 59.4±20.8% vs. 55.6±21.0%, p = 0.002). The A1 index did not show any significant variations across all three sleep quality parameters. The A2+A3 index behaved similarly to the CAP rate with decreasing values for each subjective measure (all: p < 0.001). Conclusion CAP rate, especially A2+A3-phases, are reduced in older men who report good sleep quality, while A1 index did not show any significant relationship with subjective sleep quality measures. Hence, CAP is an indicator of sleep quality.

The Relationship

Objectives: the current study aimed to investigate the relationship between physical activity (PA) level and inhibitory control performance and then to determine whether this association was mediated by multiple sleep parameters (i.e., subjective sleep quality, sleep duration, sleep efficiency, and sleep disturbance). Methods: 180 healthy university students (age: 20.15 ± 1.92 years) from the East China Normal University were recruited for the present study. PA level, sleep parameters, and inhibitory control performance were assessed using the International Physical Activity Questionnaire (IPAQ), the Pittsburgh Sleep Quality Index Scale (PSQI), and a Stroop test, respectively. The data were analyzed using structural equation modeling. Results: A higher level of PA was linked to better cognitive performance. Furthermore, higher subjective sleep quality and sleep efficiency were associated with better inhibitory control performance. The mediation analysis revealed that subjective sleep quality and sleep efficiency mediated the relationship between PA level and inhibitory control performance. Conclusion: our results are in accordance with the literature and buttress the idea that a healthy lifestyle that involves a relatively high level of regular PA and adequate sleep patterns is beneficial for cognition (e.g., inhibitory control performance). Furthermore, our study adds to the literature that sleep quality and sleep efficiency mediates the relationship between PA and inhibitory control performance, expanding our knowledge in the field of exercise cognition.

Abstract Introduction With steadily growing numbers of patients with a depressive disorder, the effect of antidepressants on sleep architecture is of increasing concern. One major oral antidepressant medication is trazadone, which has also been prescribed in low doses for sleep insomnia treatment. Here, we investigate the effect of trazadone on NREM sleep instability also known as cyclic alternating pattern (CAP) in community-dwelling older men. Methods CAP was scored in overnight EEG recordings from 41 older men on trazadone (TRZ) and 50 age-matched men who did not use trazadone (NTRZ), participating in the Osteoporotic Fractures in Men Sleep Study. A high performance automated detection system determined the ratio between CAP time and NREM sleep time (CAP rate), the number of A1-phases per hour of NREM sleep (A1 index), and the number of A2+A3-phases per hour of NREM sleep (A2+A3 index). The effect of TRZ on CAP parameters was determined using the Mann-Whitney U test. Results CAP rate was significantly decreased in men using trazadone (NTRZ: 58.2±19.7%, TRZ: 47.9±15.9%) as compared to non-trazadone user (p < 0.01). Subtype indices did not show any significant difference between both groups but to some extent less frequent A2-A3 phases for TRZ user (A1-phases: NTRZ 13.0±18.7 no./h vs. TRZ 10.8±20.4 no./h, p = 0.35; A2+A3-phases: NTRZ 51.5±33.7 no./h vs. TRZ 44.7±23.3 no./h, p = 0.068). Conclusion CAP rate was significantly decreased in older men on trazadone as compared to older men who did not use trazadone, suggesting that trazadone usage has a stabilising effect on sleep micro-structure.

BACKGROUND As an evidence-based psychotherapy for treating insomnia, cognitive behavioral therapy for insomnia (CBT-I), which helps people with sleep problems to change their unhelpful sleep-related beliefs and habits, has been well-established in older adults. Recently, the utilization of mobile CBT-I apps has been getting attention from mental health professionals and researchers; however, whether mobile CBT-I apps are usable among older users has yet to be determined. OBJECTIVE The aims of this study were to explore the relationships between subjective sleep quality and subjective memory complaints and depressive symptoms; to explore the relationship between perceived difficulty in mobile app use and usability of the mobile phone–based self-help CBT-I app, named MIND MORE, in urban community-dwelling Korean older adults; to compare changes in subjective sleep quality from pre-intervention to post-intervention, during which they used the mobile app over a 1-week intervention period; and evaluate adherence to the app. METHODS During the 2-hour training program delivered on 1 day titled “Overcoming insomnia without medication: How to use the ‘MIND MORE’ mobile app for systematic self-management of insomnia” (pre-intervention), 41 attendants were asked to gain hands-on experience with the app facilitated by therapists and volunteer workers. They were then asked to complete questionnaires on sociodemographic characteristics, subjective evaluation of mental health status (ie, depression, memory loss and impairment, and sleep problems), and app usability. For the 1-week home-based self-help CBT-I using the app (post-intervention), 9 of the 41 program attendants, who had already signed up for the pre-intervention, were guided to complete the given questionnaires on subjective evaluation of sleep quality after the 1-week intervention, specifically 8 days after the training program ended. RESULTS Due to missing data, 40 of 41 attendants were included in the data analysis. The main findings of this study were as follows. First, poor subjective sleep quality was associated with higher ratings of depressive symptoms (40/40; ρ=.60, <i>P</i>&lt;.001) and memory complaints (40/40; ρ=.46, <i>P</i>=.003) at baseline. Second, significant improvements in subjective sleep quality from pre-intervention to post-intervention were observed in the older adults who used the MIND MORE app only for the 1-week intervention period (9/9; <i>t</i><sub>8</sub>=3.74, <i>P</i>=.006). Third, apart from the program attendants who did not have a smartphone (2/40) or withdrew from their MIND MORE membership (3/40), those who attended the 1-day sleep education program adhered to the app from at least 2 weeks (13/35, 37%) to 8 weeks (2/35, 6%) without any further contact. CONCLUSIONS This study provides empirical evidence that the newly developed MIND MORE app not only is usable among older users but also could improve subjective sleep quality after a 1-week self-help intervention period.
