“…Regarding sleep quality, results of the present study revealed that participants who endorsed sleep concerns had lower scores on neuropsychological tests and assessments of functional capacity, as compared to those who endorsed no sleep problems. These findings are also in line with published research indicating that sleep problems have been associated with poorer functional capacity (Brimah et al, 2013; Chien & Chen, 2015; Vincent et al, 2021) and worse cognitive functioning (Ju et al, 2014; Kronholm et al, 2009; Potvin et al, 2012; Yaffe et al, 2014) in older age. Additionally, extant studies have suggested that sleep problems may be related to processes that age the brain and may result in brain atrophy and progression of cognitive impairment (Sexton et al, 2014; Yaffe et al, 2014).…”

“…To illustrate, both excess sleep (>8 hr) and insufficient sleep (<6 hr) have been shown to predict diminished functional capacity (Brimah et al, 2013). Similarly, poor sleep quality has been significantly associated with physical disability (Chien & Chen, 2015), but sleep duration has been linked with more global functional impairment in older adults (Vincent et al, 2021). In another study, sleep quality but not duration was associated with the development of physical impairment (Campanini et al, 2019).…”

Research suggests that clinical management of cognitive impairment can occur through interventions targeting lifestyle factors, such as physical exercise and sleep quality. The present study examined the associations among lifestyle factors (exercise and sleep quality), cognition, and functional capacity in older adults (ages 56–94) who completed an outpatient neuropsychological evaluation ( N = 356). Exercise habits and sleep quality were accessed using a self-report questionnaire and a clinical interview. Cognitive functioning was assessed using the Dementia Rating Scale-2 (DRS-2). Functional capacity was measured by the Texas Functional Living Scale (TFLS). Results indicated that physical exercise and sleep quality were positively associated with better cognitive functioning and functional capacity. Further research is needed to elucidate the relationship between lifestyle factors, cognition, and functional capacity in older adults.

“…Second, our study included sleeping time in solitude episodes and it is subject to debate whether sleeping in the presence of others, such as the partner, could be counted as being in solitude. Older adults typically sleep 7–8 hr (Vincent et al, 2020 ). In our study, there were only 55 (2%) episodes that lasted 8 hr or shorter and 245 (10%) episodes lasted 10 hr or shorter.…”

Time spent on being with others (social interactions) and being alone (solitude) in day to day life might reflect older adults' agentic regulatory strategies to balance the needs to belong and to conserve energy. Motivated from a joint lifespan psychological and social relationship theoretical perspective, this study examined how time spent on social interactions and solitude alternatively unfolds within individuals in daily life, relating to individual differences in trait-level well-being and fatigue. Over 21 days, a total of 11,172 valid records of social interactions were collected from 118 older adults (aged 65-94 years) in a smartphone-based event-contingent ambulatory assessment study in Switzerland. On average, a social interaction episode lasted 39 min and a solitude episode lasted 5.03 hr. Multilevel models showed that, at the within-person level, a longer-than-usual social interaction preceded and was followed by a longer-thanusual solitude episode. Moderator analyses showed that older adults with higher trait life satisfaction and lower trait fatigue spent even more time in social interactions after longer solitude episodes, amplifying the solitude-then-interaction association. Our findings suggest that whereas social interaction is a means to improve well-being, solitude is also an integral part in older adults' daily life supporting energy recovery.

“…Functional limitations have also been noted to follow from sleep problems in the National Health and Nutrition Examination Survey (N =6020 adults who were older than 65 years) [19]. In this study, those who had short sleep (less than five hours) as well as those with long sleep (greater than nine hours) had inferior performance on 19 functional tasks including basic activities of daily living such as dressing and eating.…”

Sleep Problems in Aging (Ageing) Adults: A Narrative Review

The recent literature on sleep problems in aging (ageing) adults has primarily focused on negative effects as well as risk factors, buffers, and interventions. The sleep problems have typically been self-reported or measured by actigraphy. The prevalence rates for sleep problems starting at age 60 have been variable, ranging from a low of 18% in the UK to a high of 50% in China, a variability that may relate to the type of sleep data and/or cross-cultural variation. Psychological effects have included dissatisfaction with life, unhealthy aging and affective/depressive mood states. Physical effects have included elevated blood pressure, impaired functionality, frailty, comorbidity and immune dysfunction. Cognitive impairment has also resulted from sleep problems, and aging brain biomarkers have included shorter telomere length, reduced gray matter volume and earlier mortality. Psychological risk factors have included meta-cognitive beliefs, worrying, loneliness, poor relationships and depression. Physical risk factors have included inactivity, napping and comorbidity. Buffers/protective factors have included retirement, light exercise, consumption of vegetables and melatonin as a sleep medication. Only a couple interventions could be found in this recent literature on sleep in aging adults including Cognitive Behavior Therapy and exercise. A few potential underlying mechanisms for disturbed sleep in aging adults include decreased vagal activity, increased connectivity in the brain making disconnecting for sleep difficult, inflammation and orexins. Although the data highlight the severity of sleep problems in the aging, they have been primarily based on self-report surveys that have yielded mixed results across samples. Sleep Problems in Aging (Ageing) Adults: A Narrative ReviewThis narrative review involved entering the terms sleep and aging (ageing) into PubMed and PsycINFO. The search yielded 735 papers for the last five years. However, following exclusion criteria including case studies and non-English language papers, this review is a summary of the research reported in 67 papers. The recent literature is predominantly focused on negative effects of sleep problems along with studies on risk factors, buffers and interventions. This narrative review is accordingly divided into sections on prevalence of sleep problems in the aging, negative effects, risk factors, buffers and interventions. These are followed by sections on potential underlying mechanisms for sleep problems in the aging and methodological limitations of the research.
