Introduction: Aging is a natural process that occurs in all individuals. Due to the increase in aging figures worldwide, the diagnosis of mild cognitive impairment and other dementia syndromes has increased. An element of essential relevance in protecting against the risk of suffering from dementia is the cognitive reserve. Objective: To indicate the levels of cognitive reserve in a sample of Cuban older adults with Mild Cognitive Impairment. Methods: An exploratory study was carried out using questionnaires, with a cross-sectional, quantitative design. The sampling was non-probabilistic and intentional, obtaining a sample of 51 older adults with mild cognitive impairment. The information collection was carried out from the Cognitive Reserve Scale (CRS). Quantitative data was analyzed through frequency analysis. Results: Most of the participants showed higher levels of cognitive reserve for carrying out activities of daily life and for relating to other people. The dimensions most affected were Formation / Information and Hobbies. Conclusions: The research allowed a preliminary approach to the cognitive reserve of older adults. It would be interesting to conduct investigations of this nature in larger samples, including groups of healthy controls, which would allow comparison of results. In addition, it would be relevant to investigate the impact of institutionalization. Keywords: older adult, cognitive reserve, Mild Cognitive Impairment.

The Impact

Background Few studies have demonstrated the impact of characteristics like age and sex on the association between hand grip strength (HGS) and mild cognitive impairment (MCI). In this cross-sectional study, we aimed to examine the effects of sex and age on the relationship between HGS and MCI. Methods We enrolled older adults age ≥60 years (n = 1009) and measured HGS and MCI in all participants. We analyzed the differences in MCI prevalence among the different variables. The role of sex and age in the association between MCI and HGS was analyzed using binary logistic regression. Results Women had significantly higher prevalence of MCI than men, as did the older group (age ≥70 years) compared with the younger group (age 60–70 years). In men, the low and middle HGS tertiles were significantly associated with MCI. In contrast, only the low tertile of HGS was associated with MCI in women. In the older group, the low tertile of HGS was significantly associated with MCI, which was not observed in the younger group. Conclusions HGS was associated with MCI in older adults, and this association was stronger in men. HGS may be useful for evaluating MCI in older adults.

BACKGROUND Coronavirus disease 2019 has forced worldwide the implementation of unprecedented restrictions to control its rapid spread and mitigate its impact. The Spanish government has enforced social distancing, quarantine and home confinement. This restriction of daily life activities and separation from loved ones may lead to social isolation and loneliness with health-related consequences in community-dwelling older adults with mild cognitive impairment or mild dementia and their caregivers. Additionally, an inadequate access to healthcare and social support services may aggravate chronic conditions. Technology home-based interventions emerge for combating social isolation and loneliness preventing the risk of viral exposure. OBJECTIVE The aim of this cohort study is to explore, analyze and determine the impact of social isolation on: 1) cognition, quality of life, mood, technophilia and perceived stress of community-dwelling older adults with mild cognitive impairment or mild dementia, and on caregiver burden; 2) health and social care services access and utilization, and 3) cognitive, social and entertainment use of ICTs. METHODS This study will be conducted in the Spanish region of Andalucía (Málaga). In total 200 dyads, consisting of a person with mild cognitive impairment or mild dementia (PMCI/MD) and their informal caregiver will be contacted by telephone. Potential respondents will be participants of the SMART 4 MD (N=100) and TV-AssistDem (N=100) clinical trials. RESULTS The change in means in the variables will be analyzed comparing baseline results in the previous studies with those during and after confinement using the ANOVA test of repeated measures or the non-parametric Friedman test if appropriate. The performance of a multivariate analysis of variance (ANCOVA) to introduce possible covariates will also be contemplated. A 95% confidence level will be used. CONCLUSIONS If the hypothesis is proven, these findings will demonstrate the negative impact of social isolation due to the COVID-19 confinement on cognition, quality of life, mood, and perceived stress of community-dwelling older adults with mild cognitive impairment and mild dementia, the impact on technophilia, caregiver burden, and health and social care services access and utilization; and the cognitive, social and entertainment use of ICTs during the COVID-19 confinement and afterwards.

Community Dwelling Older Adults

High-level depressive symptoms have been reported in individuals with mild cognitive impairment (MCI), resulting in increased risk of progression to dementia. However, studies investigating the correlates of depressive symptoms among this population are scarce. This study aimed to investigate the significant socio-demographic, lifestyle-related and disease-related correlates of depressive symptoms among this cohort. Cross-sectional data were obtained from a sample of 154 Chinese community-dwelling older adults with MCI. MCI subjects were screened by the Montreal Cognitive Assessment. Depressive symptoms were measured by the Geriatric Depression Scale. Possible correlates of depressive symptoms in individuals with MCI were explored by multiple linear regressions. The prevalence of depressive symptoms among Chinese older adults with MCI was 31.8%. In multiple regression analysis, poor perceived positive social interaction, small social network, low level of physical activity, poor functional status, subjective memory complaint, and poor health perception were correlated with depressive symptoms. The findings highlight that depressive symptoms are sufficient to warrant evaluation and management in older adults with MCI. Addressing social isolation, assisting this vulnerable group in functional and physical activities, and cultivating a positive perception towards cognitive and physical health are highly prioritized treatment targets among individuals with MCI.

There are no studies on the association between food insecurity and mild cognitive impairment (MCI). Thus, cross-sectional, community-based data on individuals aged ≥50 years from the World Health Organization’s Study on Global AGEing and Adult Health (SAGE) conducted in South Africa (2007–2008) were analyzed to assess this association. The definition of MCI was based on the National Institute on Ageing-Alzheimer’s Association criteria. Past 12-month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Multivariable logistic regression analysis was conducted. The sample consisted of 3,672 individuals aged ≥50 years [mean (SD) age 61.4 (18.3); 56% females]. The prevalence of MCI was 8.5%, while 11.0% and 20.8% experienced moderate and severe food insecurity, respectively. After adjustment for potential confounders, moderate and severe food insecurity were associated with 2.82 (95%CI = 1.65–4.84) and 2.51 (95%CI = 1.63–3.87) times higher odds for MCI compared with no food insecurity, respectively. The OR for those aged ≥65 years with severe food insecurity was particularly high (OR = 3.87; 95%CI = 2.20–6.81). In conclusion, food insecurity was strongly associated with MCI among South African older adults. Future longitudinal research is required to assess whether addressing food insecurity may reduce risk of MCI and subsequent dementia.

Abstract Background Barriers to the early detection of mild cognitive impairment (MCI) and dementia can delay diagnosis and treatment. myMemCheck® was developed as a rapid free cognitive self-assessment tool that can be completed at home to identify older adults that would benefit from a more comprehensive cognitive evaluation. Objective Two prospective cross-sectional studies were conducted to examine the psychometric properties and clinical utility of myMemCheck®. Methods In Study 1, participants were independent living residents referred to an outpatient memory clinic (N = 59); older adults in the community and post-acute nursing home residents (N = 357) comprised Study 2. Results Psychometric analyses were performed on cognitive and psychological testing data, including myMemCheck®. myMemCheck® evidenced adequate reliability and strong construct validity. Receiver operating characteristic analysis evidenced an optional myMemCheck® cut score for identifying older adults at risk for MCI or dementia. myMemCheck® explained 25% of cognitive status beyond basic patient information. Conclusions myMemCheck® may help fast-track the diagnostic process, facilitate appropriate referrals for cognitive and neuropsychological evaluation, reduce assessment burden in health care and prevent negative outcomes associated with undetected cognitive impairment.
