This paper demonstrates the effects of education on cognitive functioning which could serve as an alternative preventive method to halt or delay cognitive decline in older adults. The purpose of this proposal is to discuss and illustrate the benefits of improving cognitive ability through continuing education. As such, taking advantage of educational programmes that are already in place would not only provide mental stimulation for older adults, but would be a source for social networking, as well as technology training and physical education activities. To establish a link between cognition and education, this paper provides examples from a number of studies as well as a review of a longitudinal study on educational differences in the prevalence of dementia. The findings of this systematic review revealed a connection between cognitive decline and education after considering regions and economic status. Suggestions from these reviews imply that keeping one’s mind stimulated could be influential in delaying the onset of dementia resulting in possibly extending the time older adults are independent.

Community Dwelling Older Adults

Background: Previous studies have indicated that B vitamin deficiencies are an essential cause of neurological pathology. There is a need to provide evidence of the benefit of B vitamins for the prevention of cognitive decline in community-dwelling older adults. Objective: To examine the association between intake and plasma levels of vitamins B12, B6, and folate and cognitive function in older populations through a systematic review and meta-analysis. Methods: Medline (PubMed), EMBASE, and Cochrane databases were used to search the literature though August 8, 2019. We included observational population-based studies evaluating the association between concentrations or intake levels of vitamins B6, B12, or folate and cognition in older adults aged ≥45 years. The quality of all studies was assessed by the modified Newcastle-Ottawa Scale. Odds ratios (ORs) and hazard ratios (HRs) were analyzed by the random-effects model. Sensitivity analyses were conducted by excluding the studies with significant heterogeneity. Results: Twenty-one observational studies with sample sizes ranging from 155–7030 were included in the meta-analysis. Higher levels of vitamin B12 (OR = 0.77, 95% CI = 0.61–0.97) and folate concentration (OR = 0.68, 95% CI = 0.51–0.90) were associated with better cognition in cross-sectional studies, but not in sensitivity analyses or prospective studies. High vitamin B6 concentrations showed no significant benefit on cognition and dementia risk. Prospective studies did not provide substantial evidence for the relationship. Conclusion: The results from our meta-analysis suggest that vitamins B12, B6, and folate may not be modifiable risk factors for slowing cognitive decline among community-dwelling older individuals.

Abstract The US population over 65 is projected to increase to 21% by 2050. Given mobility issues arising from health concerns, economic status changes, loss of friends and partners, older people are at a higher risk for social isolation and loneliness. Since the declaration of national emergency for COVID-19 on March 13, 2020, many older adults have not been able to connect with others in traditional ways. Instead, activities and contacts have been facilitated virtually via videoconferencing or phone calls to maintain physical and social distance. Amidst COVID-19, the transition to using technologies to connect socially and reduce loneliness has been a critical factor in preventing social isolation and loneliness. Identifying effective strategies involving the use of technology, designing new ways to deliver services virtually, and developing educational programs to promote technology is vitally necessary. This systematic review explored the relationship between technology use and social isolation or loneliness, and examined interventions that reduced social isolation in older adults. A unified strategy was used to systematically search seven databases (MEDLINE, PubMed, Embase, CINAHL, Web of Science, PsycInfo, and AgeLine) to examine qualitative and quantitative studies published in English between 2010 and 2020. Preliminary results indicate that technology can alleviate social isolation and loneliness in older adults despite some mixed results. The findings of this study will provide a foundation for policymakers and practitioners to shape policies and design programs that help older adults to alleviate social isolation and loneliness, particularly amidst the COVID-19 pandemic.

Background. Cognitive decline occurs in all persons during the aging process and drugs can only alleviate symptoms and are expensive. Some researches demonstrated that Tai Chi had potential in preventing cognitive decline while others’ results showed Tai Chi had no influence on cognitive impairment. Therefore, we conduct a systematic review and meta-analysis to assess the efficacy and safety of cognitive impairment patients practicing Tai Chi. Methods. A comprehensive literature search was carried out in multiple databases, including PubMed, Cochrane, MEDLINE (Ovid), Web of Science, Embase, Scopus, PsycInfo (Ovid), CKNI, Wan Fang, VIP, SinoMed, and ClinicalTrails, from their inception to 1 July 2020 to collect randomized controlled trials about practicing Tai Chi for patients with cognitive impairment. Primary outcomes included changes of cognitive function and secondary outcomes included changes of memory functions. Data were extracted by two independent individuals and Cochrane Risk of Bias tool version 2.0 was applied for the included studies. Systematic review and meta-analysis were performed by RevMan 5.3 software. Results. The results included 827 cases in 9 studies, of which 375 were in the experimental group and 452 were in the control group. Meta-analysis showed that Mini-Mental State Examination WMD = 1.52, 95% CI [0.90, 2.14]; Montreal Cognitive Assessment WMD = 3.5, 95% CI [0.76, 6.24]; Clinical Dementia Rating WMD = −0.55, 95% CI [−0.80, −0.29]; logical memory delayed recall WMD = 1.1, 95% CI [0.04, 2.16]; digit span forward WMD = 0.53, 95% CI [−0.65, 1.71]; and digit span backward WMD = −0.1, 95% CI [−0.38, 0.19]. No adverse events were reported in the included articles. Conclusion. There is limited evidence to support that practicing Tai Chi is effective for older adults with cognitive impairment. Tai Chi seems to be a safe exercise, which can bring better changes in cognitive function score.
