Improve Sleep Quality

Abstract Sleep is important for memory consolidation, hence the disruption of normal sleep patterns as a result of age-related changes in the circadian system could be one of the contributors to memory impairment among older adults. It is now well-established that light is the main environmental element that synchronizes circadian rhythms. An appropriate lighting condition can be considered as a non-pharmacological solution to improve the sleep quality of individuals and consequently their overall health and well-being. The present study investigates the effectiveness of two proposed whole-day lighting interventions (L1 and L2) applied by Tunable White Lighting Technology (TWLT) on sleep quality and cognitive performance in older adults. Both lighting interventions provide a high illuminance level (500 lux) in the morning and then the illumination is dimmed gradually throughout the day and reached 100 lux in the evening. However, while L1 offers a constant Correlated Color Temperature (CCT) of 2700K, during the L2 intervention, the CCT is changing in the range of 6500K – 2700K from morning towards evening. Fifteen healthy older adults (mean age = 73.2 years; 12F) participated in a 41-day counterbalanced crossover study. Participants were exposed to each lighting condition for 9 days. Actigraphy, standard questionnaires (PROMIS and PSQI), and tests (Trail Making Test (TMT) A & B and Digit Symbol Substitution Test (DSST)) were employed to measure sleep quality and cognitive performance before, during, and after lighting interventions. Significant improvements in sleep quality and cognitive performance were found for both lighting interventions with better outcomes for L2.

Abstract There is limited evidence examining associations between diet and cognitive performance (CP) in older adults. We used the 2011-2014 National Health and Nutrition Examination Survey to determine if meeting dietary recommendations was associated with CP in adults 60+ years of age. Diet was based on the healthy eating index (HEI) 2015 and categorized into quintiles (higher quintiles indicating healthier diet). CP was based on word list learning, animal naming, and digit symbol substitution test, with scores above 25th percentile indicating adequate performance. Multivariate logistic regression modeling was conducted and adjusted for potential cofounders. A total of 3,068 participants completed the CP tests. A slightly higher percentage of participants were female (54.0%), predominantly White (80.5%) and the largest percentage (54.7%) was 60 to 69 years of age. The mean HEI-2015 score (0-100) was 54.89 (SE = 0.56). High CP scores increased with healthier dietary quintiles. However, results were only significant (p for trend <0.05) for digit symbol substitution test when comparing those in the highest quintile (82.53%) to those in the lowest (70.23%). Compared with participants in the lowest quintile of HEI-2015, participants in the highest quintile had a two-fold increased odds of better digit symbol substitution test scores, after adjusting for confounders (Odds Ratio [OR]: 1.96, 95% Confidence Interval [CI]: 1.28-3.01). Results showed that meeting healthy diet recommendations is associated with improved digit symbol substitution test, a marker of attention, processing speed and executive function. Future research should consider the role of diet in older adults to improve cognitive performance.

Hypnotic Suggestions

AbstractSlow-wave sleep (SWS) is fundamental for maintaining our health and well-being, and SWS is typically reduced in stress-related sleep disturbances and age-related sleep disorders. We have previously reported that exposure to hypnotic suggestions before sleep effectively increases the duration of SWS during a midday nap in younger and older women suggestible for hypnosis.However, it remains unclear whether this beneficial effect of hypnosis on SWS can be generalized to night-time sleep and men. Therefore, we tested the effect of the hypnotic suggestions on SWS across an 8 hours night-time sleeping interval in 43 healthy young French-speaking subjects (19 males) of high and low suggestibility. In accordance with our previous results, listening to hypnotic suggestions before sleep increased the amount of SWS in highly suggestible subjects significantly by 13 min compared to a control condition in both genders. Particularly in the first hour, slow-wave activity was significantly increased after hypnosis as compared to the control night in high suggestible. The hypnosis-induced benefits on objective sleep parameters were also reflected in increased subjective sleep quality ratings. Our results demonstrate that hypnotic suggestions are an effective tool to deepen sleep and improve sleep quality also across a whole night of sleep in young healthy men and women. Our findings provide an important basis for the examination and potential application of hypnosis to improve deep sleep in populations with sleep disturbances.

Abstract Cerebrovascular disease (CvD) is the second most common cause of dementia. Its associated pathology, such as white matter lesions (WML), is associated with reduced cognition. Due to the high variability, the relevance of WML location remains unknown. We hypothesised that although the location of WMLs may appear sporadic, they may actually lie within common functional networks. We used novel imaging methods to map the location of WMLs in a clinical sample with the functional connectivity associated with the same location in the human connectome. This identified the functional networks containing the largest WML load (>50%) in older adults with CvD. We then analyzed the association between level of disruption to these networks and measures of global cognition and executive functions. Included in this study were 164 older adults (>55 years old) with CvD. Cognition was assessed using the: 1) Montreal Cognitive Assessment (MoCA); 2) Stroop Colour Word Test; 3) Trail Making Tests; and 4) Digit Symbol Substitution Test. Our results found that the visual network and ventral attention network (VAN) surpassed the 50% overlap threshold with 85% and 66% overlap respectively. Additionally, after controlling for multiple comparisons and age, the level of disruption to the VAN was significantly associated with poorer global cognition, as measured by the MoCA (p=.001). These novel findings identify the functional networks most affected by the presence of WMLs in older adults with CvD and suggest that the disruption to the VAN caused by WML load may underlie the deficits seen in cognition in this population.

Effect Of Age

Vibrotactile feedback (VTF) has been shown to improve balance performance in healthy people and people with vestibular disorders in a single-task experimental condition. It is unclear how age-related changes in balance affect the ability to use VTF and if there are different attentional requirements for old and young adults when using VTF. Twenty younger and 20 older subjects participated in this two-visit study to examine the effect of age, VTF, sensory condition, cognitive task, duration of time, and visit on postural and cognitive performance. Postural performance outcome measures included root mean square of center of pressure (COP) and trunk tilt, and cognitive performance was assessed using the reaction time (RT) from an auditory choice RT task. The results showed that compared with younger adults, older adults had an increase in COP in fixed platform conditions when using VTF, although they were able to reduce COP during sway-referenced platform conditions. Older adults also did not benefit fully from using VTF in their first session. The RTs for the secondary cognitive tasks increased significantly while using the VTF in both younger and older adults. Older adults had a larger increase compared with younger adults, suggesting that greater attentional demands were required in older adults when using VTF information. Future training protocols for VTF should take into consideration the effect of aging.

Abstract Older adults are vulnerable to particular risk factors that contribute to lower well-being and poorer functioning. With the COVID-19 pandemic, the importance of social support has been highlighted in media reports because of its well-known beneficial effects on overall well-being. However, as adults age, social networks, contacts, and activities naturally decrease. These age-related losses are often difficult, if not impossible, to replace. Pets have recently been recognized as a valuable source of social support for many older adults, providing both physical and psychological benefits through mutual connection and behavioral activation. Previous studies have examined how human social support or pet social support enhance older adults’ well-being (i.e., positive emotions, engagement, relationships, accomplishment, and meaning). However, there is a gap in our scientific knowledge as previous research has not evaluated if pet social support can serve as a protective factor in the absence of adequate human social support. Current analyses, with 141 older adult participants, suggests that pet owners with a positive attachment to their pet experience higher well-being as pets serve as a coping resource that protects against common life stressors. Similar to human social support, pet social support appears to be a protective factor that also promotes and fosters a sense of well-being in older adults. Support in late life is especially important for families and agencies to be attuned to, especially during a global pandemic.

Abstract There has been a great deal of research on technology to support older adults in their performance of Activities and Instrumental Activities of Daily Living. There has been substantially less research, however, on exploring technology solutions that support hobbies and leisure. This is unfortunate, as quality of life and well-being are determined by more than just one’s ability to manage everyday tasks. An overview will be presented of research the Center for Research and Education on Aging and Technology Enhancement (CREATE) has conducted over two decades with the goals of understanding and supporting older adults’ performance of technology-based leisure activities. Many of these studies have involved videogaming, where there exists a substantial age-related digital divide. CREATE has evaluated older adults’ attitudes and game experiences through survey and research studies and has even recorded longitudinal gameplay. How these findings can be applied to support technology-based leisure activities will be expanded upon. Part of a symposium sponsored by Technology and Aging Interest Group.

This study examined age-related associations between goal disengagement capacities, emotional distress, and disease severity across older adulthood. Given that an age-related increase in the experience of stressors might render important goals unattainable, it is expected that goal disengagement capacities would predict a decrease in the severity of experienced illness (i.e., the common cold) by preventing emotional distress (i.e., depressive symptoms), particularly so among individuals in advanced (as compared to early) old age. This hypothesis was tested in a 6-year longitudinal study of 131 older adults (age range = 64 to 90). Regression analyses showed that goal disengagement capacities buffered 6-year increases in older adults’ cold symptoms, and that this effect was significantly pronounced among older-old participants. Mediation analyses further indicated that changes in depressive symptoms exerted an indirect effect on the age-related association between goal disengagement and changes in cold symptoms. The study’s findings suggest that goal disengagement capacities become increasingly important for protecting emotional well-being and physical health as older adults advance in age.

Background: Social status is the standing of a person or group in the social hierarchy, and is perceived to change across the life span from low social status in early life, to peak in midlife, and to a decline thereafter. As threats to subjective social status are known to be detrimental to individuals’ health, it is important to better understand how older adults perceive themselves and others in terms of age-related social status. Objective: We examined status ambivalence – the potential discrepancy between how older adults’ perceive social status for themselves compared to older adults in general. Method: Study 1 used qualitative data from 37 semi-structured interviews with older adults to assess perceptions of social status. Study 2 used quantitative survey data from 114 older adults who completed explicit and implicit measures of social status. Results: Study 1 (n = 37, meanage = 71.72, SDage = 5.69; 81.1% women) provided preliminary evidence for status ambivalence such that older adults reported unequivocal low social status for other older adults but a more ambivalent perception of their own social status. Study 2 (n = 114, meanage = 64.32, SDage = 8.98, 57.9% women) compared implicit and explicit measures of social status revealing that older adults consistently perceive older adults to have low social status but again show a more ambivalent perception of their own social status. Conclusion: We discuss status ambivalence as a potential protective mechanism in the context of negative societal perceptions of age-related social status that may be important for well-being in later life.
