Psychological resilience is protective against cognitive deterioration in motor neuron diseases. Amyotroph Lateral Scler Frontotemporal Degener 2024:1-9. [PMID: 39138961 DOI: 10.1080/21678421.2024.2385690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 07/14/2024] [Accepted: 07/22/2024] [Indexed: 08/15/2024]
Abstract
OBJECTIVES Recent studies suggest that psychological resilience (PR) is associated with more well-preserved cognition in healthy subjects (HS), but an investigation of such phenomenon in patients with motor neuron diseases (MNDs) is still lacking. The aim of our study was therefore to evaluate PR and its relationship with baseline cognitive/behavioral and mood symptoms, as well as longitudinal cognitive functioning, in MNDs. METHODS 94 MND patients and 87 demographically matched HS were enrolled. PR was assessed using the Connor-Davidson Resilience Scale (CD-RISC). Patients were further evaluated both at baseline and every 6 months for cognitive/behavioral disturbances using the Edinburgh Cognitive and Behavioral ALS Screen (ECAS), and for mood symptoms using the Hospital Anxiety and Depression Scale (HADS). CD-RISC scores were compared between patients and HS using the Mann-Whitney U test, and regression models were applied to evaluate the role of CD-RISC scores in predicting baseline cognitive/behavioral and mood measures, as well as longitudinal cognitive performances, in MND patients. RESULTS MND cases showed significantly greater PR compared to HS (p from <0.001 to 0.02). In MNDs, higher PR levels were significant predictors of both greater cognitive performance (p from 0.01 to 0.05) and milder mood symptoms (p from <0.001 to 0.04) at baseline, as well as less severe memory decline (p from 0.001 to 0.04) longitudinally. CONCLUSIONS PR is an important protective factor against the onset and evolution of cognitive/mood disturbances in MNDs, suggesting the usefulness of resilience enhancement psychological interventions to prevent or delay cognitive and mood disorders in these neurodegenerative conditions.

Effects of folic acid supplementation on cognitive function and inflammation in elderly patients with mild cognitive impairment: A systematic review and meta-analysis of randomized controlled trials. Arch Gerontol Geriatr 2024; 126:105540. [PMID: 38964091 DOI: 10.1016/j.archger.2024.105540] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 06/03/2024] [Accepted: 06/17/2024] [Indexed: 07/06/2024]
Abstract
OBJECT The aim was to assess the effect of folic acid supplementation on cognitive function and inflammatory cytokines in elderly patients with mild cognitive impairment. METHODS From its inception until February 2024, four databases including Web of Science were searched. Two researchers independently screened the literature, assessed the quality, extracted data, and conducted a meta-analysis using RevMan. RESULTS The systematic review included seven studies (with a total of 1102 participants, mean age 65-80 years), seven of which were appropriate for meta-analysis. Although a small number of studies found relatively large heterogeneity, the majority of studies showed significant benefit from folic acid supplementation, including the FSIQ (823 individuals, standardized mean difference [SMD] = 8.36, 95 % confidence interval [CI] = 0.79 - 1.08), Arithmetic (823 individuals, SMD = 0.17, 95 % CI = -0.03-0.31), Information, SMD = 1.73, 95 % CI 0.41-3.05), Digit Span (823 individuals, SMD = 0.17, 95 % CI = -0.03 - 0.31), Block Design (823 individuals, SMD = 0.26, 95 % CI 0.03-0.49), Picture Completion (823 individuals, SMD = 0.27, 95 % CI = -0.15 - 0.69) and Picture Arrangement (823 individuals, SMD = -0.12, 95 % CI = -0.26 - 0.01). Finally, folic acid supplementation had a significant effect on the reduction of most inflammatory cytokines, blood biomarkers of Alzheimer's disease, and Hcy. CONCLUSIONS Folic acid supplementation seems to have a positive impact on cognitive function in older adults with mild cognitive impairment, but further evidence of its effectiveness in improving inflammatory cytokines is needed from high-quality studies.

J Affect Disord 2024; 351:962-970. [PMID: 38346647 DOI: 10.1016/j.jad.2024.02.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 01/29/2024] [Accepted: 02/07/2024] [Indexed: 02/17/2024]
Abstract
BACKGROUND Cognitive impairment and psychological resilience are closely related in older adults, but their combined effect on mortality has not been reported. Using a nationally representative sample from the Chinese Longitudinal Healthy Longevity Study, this study examined the interactions between cognitive impairment and psychological resilience and their associations with overall survival. METHODS A total of 32,349 community-dwelling older adults (86.85 ± 11.16 years, 56.06 % female) were enrolled in 1998, 2000, 2002, 2005, 2008, 2011, and 2014; all participants were followed until 2018. Cognitive function and psychological resilience were assessed using the Mini-Mental State Examination (MMSE) and the 7-item psychological resilience questionnaire (PRQ), respectively. Illiterate subjects with an MMSE score <18, or literate subjects with an MMSE score <24 were defined as having cognitive impairment. Cox proportional risk regressions were used to analyze the association of cognitive impairment and psychological resilience with all-cause mortality. RESULTS After 146,993.52 person-years of follow-up, 23,349 older adults died. Both MMSE and PRQ scores (as continuous variables) were negatively associated with mortality risk after adjusting for all covariates. The hazard ratio (HR) of all-cause mortality for cognitive impairment was not significantly moderated by levels of psychological resilience (P-interaction = 0.094). In joint analyses, participants with combined cognitive impairment and low resilience (by the median of PRQ: < 25 points) had the highest risk of mortality (adjusted-HR: 1.56, 95%CI: 1.48-1.61), which was higher than that of patients with either condition alone. There was a significant additive interaction effect of cognitive impairment and low resilience on all-cause mortality (relative excess risk due to interaction: 0.11, 95 % CI: 0.09-0.13), and 7 % of the overall mortality risk was attributable to their synergistic effect. CONCLUSIONS Cognitive impairment and low resilience are synergistically associated with increased risk of all-cause mortality in community-dwelling older adults. The potential mechanisms underlying this combined effect warrant further exploration.

J Family Community Med 2024; 31:153-159. [PMID: 38800795 PMCID: PMC11114877 DOI: 10.4103/jfcm.jfcm_304_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 02/03/2024] [Accepted: 02/26/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Healthcare professionals (HCPs) face a variety of work-related stressors that have impact on their mental health and cognitive performance. Work resilience is a psychological resource that helps workers cope with stress and prevents unfavorable psychological impact. The aim of this study was to assess the associations between working as HCPs and cognitive function as well as work resilience. MATERIALS AND METHODS This was a comparative cross-sectional study conducted among HCPs at Suez Canal University Hospital in Ismailia Governorate, Egypt, during April 2023 to August 2023. Two hundred and thirty-five HCPs and 107 administrative employees (Admins) were invited to participate in this study. A self-administered questionnaire was used to obtain sociodemographic and other relavent data. Cognitive function was assessed with the Mini-Mental State Examination test; work resilience was assessed with the Brief Resilience Scale; and psychological distress was measured with the Depression, Anxiety, and Stress Scale - 21-items (DASS-21) scale. Statistical significance was determined by Mann Whitney U-test for continuous variables, and Chi-square test or Fisher's exact, as appropriate, for categorical variables. Multiple logistic regression models were employed to determine associations between the main outcomes (cognitive impairment and low resilience) and the main covariate (working as HCPs vs. Admins), adjusting for all potential confounders. RESULTS HCPs showed a significantly greater cognitive impairment, less resilience, and DASS-21 than the Admins. The odds of impaired cognitive function in HCPs were significantly higher than the Admins (odds ratio [OR]: 4.45, 95% confidence interval [CI]: 1.27-15.67, P = 0.020), adjusted for all potential covariates. Similarly, the odds of low resilience in HCPs were significantly higher than Admins (OR: 5.81, 95% CI: 2.72-12.44, P < 0.001), adjusted for all potential covariates. However, the adjusted association between impaired cognitive function and low resilience was not statistically significant (OR: 0.55, 95% CI: 0.23-1.33, P = 0.185). CONCLUSION HCPs had significantly impaired cognitive function and low work resilience. Workplace policies and interventions to control depression, stress, and anxiety are required as it is the encouragement of physical activity. Programs that combine positive coping skills training (e.g., relaxation training, positive thinking, and problem solving) with resilience-building interventions (e.g., taking a proactive approach to solving problems, being flexible and adaptive) should be developed, with special attention to HCPs who have a higher sense of self-efficacy.

Abstract
OBJECTIVES Resilience during old age reflects the capacity to adapt to changes and challenges associated with normative aging and is an important component of successful aging. Belief in the incremental theory of intelligence and personality could help older adults maintain cognitive functioning and social engagement, which may further contribute to their resilience. The current study investigated how implicit theories of intelligence and personality affected older adults' resilience and examined cognitive functioning and social participation as two mediators. METHOD A total of 108 older adults aged 60-92 were recruited and completed relevant scales and cognitive tasks. Path analyses were conducted to estimate the expected mediation model. RESULTS The incremental theory of intelligence, but not personality, was positively related to older adults' resilience. Both cognitive functioning and social participation mediated the effect of the implicit theory of intelligence in the model without covariates. When background variables were controlled, the mediation effect of cognitive functioning remained significant, while the link between the implicit theory of intelligence and social participation was weakened. CONCLUSION Older adults' implicit theory of intelligence plays a significant role in fostering resilience in late adulthood, especially through maintaining older adults' cognitive functioning.

Abstract
OBJECTIVES The purpose of this study was to explore whether psychological resilience can influence changes in cognitive function in older adults and provide clues and rationale for improving cognitive function and preventing the onset of dementia in the geriatric population. METHODS A total of 2495 older adults aged 60 years or older from the Ma' anshan Healthy Aging Cohort were included in the study. Participants' cognitive functioning and psychological resilience were measured using the MMSE (mini-mental state examination) scale and the SRQS (stress resilience quotient scale) scale during the 5 years of follow-up, and the association was explored. Those with MMSE scores ≤ 17 in the illiterate group, ≤ 20 in the elementary school group, and ≤ 24 in the secondary school and above group were considered cognitive impairment. RESULTS The prevalence of cognitive impairment increased from 6.89% to 14.30% during the five years of follow-up. At 5-year follow-up, the group with the highest psychological resilience had 41 (6.83%) individuals whose cognitive functioning changed from normal to cognitive impairment, while the group with the worst psychological resilience had 114 (18.33%) individuals. The study also found a significant effect of different levels of psychological resilience on changes in cognitive functioning after adjusting for potential confounders. Compared with Q1 (the reference group), the Odds ratio of cognitive decline in Q2, Q3 and Q4 groups were 0.51(0.42,0.64), 0.37(0.29,0.47) and 0.19(0.13,0.27), respectively. CONCLUSIONS Improving the level of psychological resilience in older adults may be one way to prevent the incidence of cognitive impairment.

Abstract
Cognitive impairment and dementia are burgeoning public health concerns, especially given the increasing longevity of the global population. These conditions not only affect the quality of life of individuals and their families, but also pose significant economic burdens on healthcare systems. In this context, our comprehensive narrative review critically examines the role of nutritional supplements in mitigating cognitive decline. Amidst growing interest in non-pharmacological interventions for cognitive enhancement, this review delves into the efficacy of vitamins, minerals, antioxidants, and other dietary supplements. Through a systematic evaluation of randomized controlled trials, observational studies, and meta-analysis, this review focuses on outcomes such as memory enhancement, attention improvement, executive function support, and neuroprotection. The findings suggest a complex interplay between nutritional supplementation and cognitive health, with some supplements showing promising results and others displaying limited or context-dependent effectiveness. The review highlights the importance of dosage, bioavailability, and individual differences in response to supplementation. Additionally, it addresses safety concerns and potential interactions with conventional treatments. By providing a clear overview of current scientific knowledge, this review aims to guide healthcare professionals and researchers in making informed decisions about the use of nutritional supplements for cognitive health.

Abstract
OBJECTIVES Psychological stress has been proposed as a risk factor for cognitive impairment and dementia. However, it remains unclear how an individual's stress-coping ability (i.e., psychological resilience) is related to cognition. This cross-sectional study investigated whether perceived stress and psychological resilience were associated with cognition and a modifiable dementia risk score in a large community-based sample of cognitively normal adults. The moderating effect of psychological resilience was also examined. METHODS Participants (mean age = 57 ± 7 years) enrolled in the web-based Healthy Brain Project completed the Perceived Stress Scale and the Connor-Davidson Resilience Scale. Domains of attention and working memory were assessed using the Cogstate Brief Battery (n = 1,709), and associative memory was assessed using the Cambridge Neuropsychological Test Automated Battery (n = 1,522). Dementia risk was estimated for 1,913 participants using a modified version of the Cardiovascular Risk Factors, Aging, and Incidence of Dementia dementia risk score, calculated using only readily modifiable dementia risk factors. RESULTS In separate linear regression analyses adjusted for age, sex, education, and race, greater levels of perceived stress and lower levels of psychological resilience were associated with poorer performance across all cognitive domains, as well as a higher modifiable dementia risk score. Psychological resilience did not moderate the effect of perceived stress on cognition or the dementia risk score. DISCUSSION Higher perceived stress and lower resilience were associated with poorer cognition and a greater burden of modifiable dementia risk factors. Intervention studies are required to determine if lowering stress and building resilience can mitigate cognitive deficits and reduce dementia risk.

Abstract
This study assessed the social support-cognitive function relationship in older Chinese Han adults by sex, while examining the mediating effect of resilience. Community-dwelling participants (60-94 years, M = 70.85 ± 7.31; n = 333) completed questionnaires assessing social support, resilience, and cognitive function. The mediating effect of resilience by sex was tested through structural equation modeling. Cognitive function was lower in older age groups (70-79 and ≥80 years). In structural equation modeling, social support positively predicted cognitive function, while resilience mediated this relationship in both sexes. In men, alongside the direct contribution of objective support, the relationship between subjective support and cognitive function was completely mediated by tenacity. In women, tenacity partially mediated this relationship, whereas subjective support directly predicted cognitive function. This study provides evidence of the mediating effect of resilience in the social support-cognitive function relationship among older Chinese adults, revealing important sex differences.

[PMID: 36739004 DOI: 10.1016/j.jad.2023.01.112] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 01/22/2023] [Accepted: 01/30/2023] [Indexed: 02/05/2023]
Abstract
BACKGROUND Limited epidemiological evidence exists regarding the association of social participation and psychological resilience with cognitive health. This study aimed to comprehensively investigate the effects of social participation and psychological resilience on adverse cognitive outcomes among older adults in China. METHODS We used two waves (2011 and 2014) of data from the Chinese Longitudinal Survey of Health and Longevity (CLHLS), and 9765 respondents were eligible for the subsequent screening for the present prospective analysis. The Cox proportional hazards model was utilized to examine the association of social participation and psychological resilience with cognitive impairment, cognitive decline and greater cognitive decline. The restricted cubic spline plots were applied to clarify the dose-response relationships between them. RESULTS Compared to those with low social participation, participants with high social participation had a lower hazard ratio (HR) of 0.72 (95 % confidence interval [CI]: 0.59-0.89) for cognitive impairment, 0.85 (95 % CI: 0.76-0.94) for cognitive decline and 0.78 (95 % CI: 0.67-0.90) for greater cognitive decline. Participants with high psychological resilience had an HR of 0.77 (95 % CI: 0.63-0.95) for cognitive impairment 0.85 (95 % CI: 0.76-0.94) for cognitive decline and 0.85 (95 % CI: 0.73-0.98) for greater cognitive decline compared with those with low psychological resilience. Similar effects were observed for social participation score and psychological resilience score. The dose-response analysis also showed that the risk of adverse cognitive outcomes decreased gradually with increasing social participation scores and psychological resilience scores. Additionally, the multiplicative interaction between social participation and psychological resilience was not significant. LIMITATION All information was collected by self-report, which may lead to biases in the process of information collection. CONCLUSION In this study, social participation and psychological resilience were independently associated with a lower risk of adverse cognitive outcomes, and therefore both need to be considered as broader measures to preserve cognitive health among older Chinese adults.

Nutrition Strategies Promoting Healthy Aging: From Improvement of Cardiovascular and Brain Health to Prevention of Age-Associated Diseases. Nutrients 2022; 15:nu15010047. [PMID: 36615705 PMCID: PMC9824801 DOI: 10.3390/nu15010047] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/19/2022] [Accepted: 12/21/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND An increasing number of studies suggest that diet plays an important role in regulating aging processes and modulates the development of the most important age-related diseases. OBJECTIVE The aim of this review is to provide an overview of the relationship between nutrition and critical age-associated diseases. METHODS A literature review was conducted to survey recent pre-clinical and clinical findings related to the role of nutritional factors in modulation of fundamental cellular and molecular mechanisms of aging and their role in prevention of the genesis of the diseases of aging. RESULTS Studies show that the development of cardiovascular and cerebrovascular diseases, neurodegenerative diseases, cognitive impairment and dementia can be slowed down or prevented by certain diets with anti-aging action. The protective effects of diets, at least in part, may be mediated by their beneficial macro- (protein, fat, carbohydrate) and micronutrient (vitamins, minerals) composition. CONCLUSIONS Certain diets, such as the Mediterranean diet, may play a significant role in healthy aging by preventing the onset of certain diseases and by improving the aging process itself. This latter can be strengthened by incorporating fasting elements into the diet. As dietary recommendations change with age, this should be taken into consideration as well, when developing a diet tailored to the needs of elderly individuals. Future and ongoing clinical studies on complex anti-aging dietary interventions translating the results of preclinical investigations are expected to lead to novel nutritional guidelines for older adults in the near future.

Ma Y, Leung P, Wang Y, Wang L. Psychological resilience, activities of daily living, and cognitive functioning among older male Tekun adults in rural long-term care facilities in China. SOCIAL WORK IN HEALTH CARE 2022; 61:445-467. [PMID: 36398735 DOI: 10.1080/00981389.2022.2147628] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 10/29/2022] [Accepted: 11/03/2022] [Indexed: 06/16/2023]
Abstract
Most of the rural long-term care (LTC) facilities in China are ill-equipped to manage the physical and psychological needs of older residents with dementia. These facilities mostly consist of older male Tekun (socially and economically vulnerable) adults. Preventing or delaying the onset of dementia is especially crucial for these older Tekun adults. A sample of 711 older male Tekun adults from rural LTC facilities in the Anhui province of China was used to investigate the association between psychological resilience and cognitive functioning, and to examine the moderating effect of activities of daily living (ADLs) on that association. Linear and quantile regression found that resilience was positively associated with cognitive functioning for the total sample, with a greater effect among those with a lower level of cognitive functioning. The benefit of resilience on cognitive functioning was observed only in participants with disability in ADLs. Our findings present evidence in support of interventions to foster psychological resilience and potentially improve cognitive functioning among vulnerable older adults. Resilience-promoting intervention is a strength-based approach that aligns with social work values and can be used in practice. The implications for social work practice were discussed.
