“…7,14 In addition, those with lower cognitive scores had networks that were denser, more interconnected, and contained a higher proportion of relatives. One possible explanation for this finding is that lower cognition hinders the maintenance of diverse and distant network ties, leading to smaller and denser networks.…”

“…6 Longitudinal studies show that larger social networks, 7,8 access to social resources, 9,10 and community engagement reduce dementia diagnoses. [11][12][13][14][15][16][17] Hypotheses on mechanisms by which social relationships can reduce cognitive decline include: delay of cognitive atrophy (Buse it or lose it^), 18 higher cognitive reserve, 19 and preventing stress-related cognitive declines.…”

“…To understand the full clinical consequences of lower cognition for social relationships, multiple aspects of social function should be assessed. 4,14 For example, in examining social network structure, network sizes are smaller for those with cognitive impairment, 7,8 suggesting less social support and higher potential caregiver burden. However, it is unclear whether composition of the network relationships also change.…”

Social Function and Cognitive Status: Results from a US Nationally Representative Survey of Older Adults

BACKGROUND: An early sign of cognitive decline in older adults is often a disruption in social function, but our understanding of this association is limited. OBJECTIVE: We aimed to determine whether those screening positive for early stages of cognitive impairment have differences across multiple dimensions of social function and whether associations differ by gender. DESIGN: United States nationally representative cohort (2010), the National Social life, Health, and Aging Project (NSHAP). PARTICIPANTS: Community-dwelling adults aged 62-90 years (N = 3,310) with a response rate of 76.9 %. MAIN MEASURES: Cognition was measured using a survey adaptation of the Montreal Cognitive Assessment categorized into three groups: normal, mild cognitive impairment (MCI), and dementia. We measured three domains of social relationships, each comprised of two scales: network structure (size and density), social resources (social support and social strain), and social engagement (community involvement and socializing). We used multiple linear regression to characterize the relationship of each social relationship measure to cognition. KEY RESULTS: Individuals screened as at risk for MCI and early dementia had smaller network sizes by 0.3 and 0.6 individuals (p < 0.001), and a 10 % and 25 % increase in network density (p < 0.001), respectively. For social resources, individuals at risk for MCI and dementia had 4 % and 14 % less social strain (p = 0.01), but only women had 3 % and 6 % less perceived social support (p = 0.013), respectively. For social engagement, individuals screened positive for MCI and dementia had 8 % and 19 % less community involvement (p = 0.01), but only men had 8 % and 13 % increased social involvement with neighbors and family members (p < 0.001), respectively. CONCLUSION: Changes in social functioning provide an early indication to screen for cognitive loss. Recognition that early cognitive loss is associated with differences in social function can guide counseling efforts and help identify social vulnerabilities to ease the transition to overt dementia for both patients and caregivers.

“…Community activities and gardening were also protective for incident dementia in China [17]. A longitudinal study in Sweden reported that having an extensive social network was protective for development of incident dementia [67]. The same group also reported that both social interaction and intellectual stimulation may help in preserving mental function in the elderly, because engagement in mental, social, and productive activities was associated with decreased risk for incident dementia [50].…”

Epidemiologic evidence suggests that higher occupational attainment and education, as well as increased participation in intellectual, social, and physical aspects of daily life, are associated with slower cognitive decline in healthy elderly and may reduce the risk of incident Alzheimer's disease (AD). There is also evidence from structural and functional imaging studies that patients with such life experiences can tolerate more AD pathology before showing signs of clinical dementia. It has been hypothesized that such aspects of life experience may result in functionally more efficient cognitive networks and, therefore, provide a cognitive reserve that delays the onset of clinical manifestations of dementia. In this article, we review some of the relevant literature of the noted associations between markers of cognitive reserve and AD and discuss the possible mechanisms that may explain these associations.

“…Degree of satisfaction with social contacts is closely connected with feelings of isolation among older people (Holmén & Furukawa., 2002), while an extensive social network can delay the onset of dementia (Fratiglioni et al, 2000). Frequent contacts with family and friends may thus counteract social loneliness (Drageset, 2004).…”

The purpose of this study was to describe the everyday activities and social contacts among older deaf sign language users, and to investigate relationships between these phenomena and the health and wellbeing within this group. The study population comprised deaf sign language users, 65 years or older, in Sweden. Data collection was based on interviews in sign language, including open-ended questions covering everyday activities and social contacts as well as self-rated instruments measuring aspects of health and subjective wellbeing. The results demonstrated that the group of participants was homogeneous in their productive and leisure activities, regardless of gender and age. The number of productive activities was related to all aspects of health, while the number of leisure activities was related to perceived health and subjective wellbeing. No significant relationship was found between aspects of health and subjective wellbeing and the frequency of social contacts with family/relatives or of visits at the deaf club meeting friends. It is concluded that the variety of activities at the deaf clubs are important for the subjective wellbeing of older deaf sign language users. Further research should investigate the importance and perceived value of the various activities at the deaf clubs. When evaluating the results of this study, the fact that the total number of participants was small, and the dropout rate was high, has to be borne in mind.
