“…Unlike our study one study also showed an association between loneliness and depressive symptomatology collected by the GDSVE-6 screening, which we also used in our study (59). Other recent research in depressed older adults showed loneliness as a risk factor, associated with both cognitive impairment and elevated mortality (67,68). Ausín et al,2017, identified several variables as predictive of loneliness in Spanish adults over sixty-five years of age, including functional deterioration and low satisfaction with QoL and social contacts, and the presence of mental disorders, especially anxiety (57).…”

(1) Background: Loneliness, little studied in Nursing Homes (NHs), can affect physical and mental health. We aimed to verify the prevalence of loneliness in 5 NHs and its associated factors. (2) Methods: Cross-sectional study. Older adults aged 65 or over with preserved cognitive status were included. The De Jong Gierveld Loneliness Scale was used to assess overall, social, and emotional loneliness; sociodemographic and health-related variables were collected. The chi-square (or Fisher’s) test and logistic regression were used for bivariate and multivariate analysis respectively. (3) Results: The final sample consisted of 65 participants (81.5% female) with a mean age of 84±7.13. Prevalence of overall loneliness was 70.7% (95%CI:58.2-81.4), social loneliness 44.6% (95% CI: 33.1-56.6) and emotional loneliness 46.2% (95% CI: 34.5–58.1). Overall loneliness was associated with lower perceived quality of life (Odds Ratio-OR= 5.52, 95% CI:1.25-24.38) and NH with state subsidized places (OR=0.19, 95% CI: 0.05-0.74); social loneliness with having 0-1 children (OR=0.25, 95% CI: 0.08-0.77), and emotional loneliness with depression (OR=4.54, 95% CI: 1.28-16.08) and urinary incontinence (UI) (OR=4.65, 95% CI: 1.23-17.52). (4) Conclusions: Loneliness was present in almost 71% of residents and was associated with the type of NH and poorer quality of life, emotional loneliness with depression and UI and social loneliness with having less than 2 children.

“…Because loneliness and depression are strongly interrelated in older adults (Golden et al, 2009), depressed older adults might be particularly vulnerable for the poor health outcomes associated with loneliness. Supportive of this, loneliness in depressed older adults is associated with increased mortality rates (Stek et al, 2005;Holwerda et al, 2016), and in another study loneliness was associated with poor cognitive performance only in individuals with depressive symptoms (Lam, Yu, & Lee, 2017). Thus, in depressed older adults loneliness might be an important risk factor for cognitive decline.…”

Objectives: To examine the association of social network size and loneliness with cognitive performance and-decline in depressed older adults. Method: A sample of 378 older adults [70.7 (7.4) years] with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of current depressive disorder were recruited from primary care and specialized mental health care. Cognitive performance was assessed at baseline and 2 years follow-up with the Stroop colored-word test, a modified version of the Auditory Verbal Learning Task and the Digit Span subtest from the Wechsler Adult Intelligence Scale, encompassing four cognitive domains; processing speed, interference control, memory, and working memory. Social network size was assessed with the Close Person Inventory and loneliness with the de Jong Gierveld Loneliness Scale at baseline. Results: After adjusting for baseline working memory performance, loneliness was associated with impaired working memory after 2 years [B ¼ À0.08 (À0.17 to 0.00)]. This association was no longer significant after adjusting for age, sex, education level, physical activity, alcohol use and depressive symptom severity [B ¼ À0.07 (À0.16 to 0.03)]. A backward elimination procedure revealed education level to be the only covariable to explain this association. Loneliness was not associated with impairments or decline in other cognitive domains. Social network size was not associated with cognitive impairments or decline. Conclusion: Social network size and loneliness do not predict cognitive decline in depressed older adults.

“…Donovan et al's (2017) study with 8,382 USA participants aged 65 or older concluded that, after 12 years, the effect of loneliness on cognitive function became marginally significant after controlling for depression, and that the latter is associated with a more rapid cognitive decline. Similarly, Lam et al (2017) revealed that, only among the individuals who reported higher levels of depressive symptoms, loneliness was associated with poorer cognitive function.…”

ObjectiveSocial isolation and loneliness are associated with poor health (immunity, inflammation, etc.) in ageing. The purpose of this scoping review was to investigate the link between social isolation, loneliness (as distinct constructs, in contrast to previous published work) and cognition in cognitively healthy older adults.MethodWe followed PRISMA-ScR guidelines. Our search, conducted between January 2017 and April 2021, yielded 2,673 articles, of which, twelve longitudinal studies were finally identified as meeting the inclusion criteria. Multiple cognitive functions (short-term and episodic memory, attention, and global cognitive functioning) were measured.ResultsThe results showed that both social isolation and loneliness were associated with poor cognition in ageing, with depression as a possible mediator between loneliness and poor cognition. Some studies also suggested that the link between social isolation, loneliness and cognitive decline may be bidirectional.ConclusionWe conclude that both social isolation and loneliness may have a different impact on cognition. While depression may be an important mediator between loneliness and cognitive decline, the lack of cognitive stimulation may be a greater mediator between social isolation and cognitive health.
