This study aimed to investigate whether (1) depression is associated with cognitive decline in Korean older adults and (2) the relationship between depression and cognitive function varies by gender. Using Korean Longitudinal Study of Aging data of 2006 to 2014, we studied 1787 adults aged 65 years or older who had normal cognitive function at baseline. This study examined the effects of depression on cognitive decline by using an interaction term of baseline depression and time, and compared relationships by gender. Among male participants, K-MMSE (Korean-Mini-Mental Status Examination) scores decreased with age, at an annual rate of approximately 0.465 points. Baseline depression was found to accelerate the decline in cognitive function, by approximately 0.184 points per year. Among female participants, K-MMSE scores decreased with age, at an annual rate of approximately 0.585 points. Baseline depression was not related to the decline in cognitive function. These results suggest the need for community-based programs to increase awareness of mental health problems need to be developed to encourage the use of health services to prevent or delay cognitive decline in older Korean males.

Abstract Hearing and vision impairment have been independently linked to accelerated cognitive decline in older adults, however there is limited evidence on the effect of dual sensory impairment (DSI) (both hearing and vision impairment) on cognition. Additionally, the impact of social isolation and loneliness, both correlates of DSI and independent risk factors for cognitive decline, on the DSI-cognition relationship has yet to be studied. Using data from the National Social Life, Health, and Aging Project (N=3,091), multivariable linear regression models were used to describe the cross-sectional relationship between self-reported functional sensory impairment (none, hearing only, vision only, DSI) and cognitive function, measured by the survey adapted Montreal Cognitive Assessment. We also included an interaction term in the model to investigate whether cognition is worse among older adults with sensory impairment who also are socially isolated or lonely. Participants in this sample are between 62-91 years with 15% reporting hearing impairment, 11% reporting vision impairment, and 7% reporting DSI. DSI was associated with significantly lower global cognitive function compared to no sensory impairment (-0.31 standard deviations (SD), 95% CI:-0.44 to-0.18), hearing impairment alone (-0.29 SD, 95% CI: -0.44 to -0.15), and vision impairment alone (-0.22 SD, 95% CI: -0.39 to -0.06). Furthermore, cognitive function was significantly worse among older adults with both DSI and smaller social networks (p-interaction <0.05). No differences in the DSI-cognition relationship were observed by level of loneliness. These findings add to the limited research on the relationship between DSI, social isolation and loneliness, and cognition.

AbstractObjectiveTo analyse the relationship between serum folate (SF), vitamin B12 and impaired cognitive function in the Chilean elderly.DesignWe analysed the relationships between impaired cognitive function and age, SF (µg/l) and vitamin B12 (pg/ml) with Student’s t test, as well as between impaired cognitive function and gender, educational level, residence area, diabetes and hypertension with the χ2 test. Multiple logistic regressions with interactions were estimated to assess the impact of SF on impaired cognitive function according to these methods.SettingChile.SubjectsOlder adults (>65 years, n 1051), drawn from representative households of a national prevalence study, assessed using the Modified Mini Mental Status Examination (MMMSE). Individuals with altered MMMSE scores (≤13 points) were sequentially assessed using the Pfeffer Functional Activities Questionnaire (PFAQ).ResultsMultivariate models using the MMMSE demonstrated an increased risk of impaired cognitive function for seniors who had hypertension, diabetes and higher vitamin B12 levels. SF and its square (SF2) were statistically significant, indicating that this predictor of impaired cognitive function displays a U-shaped distribution. The interaction between SF and vitamin B12 was not statistically significant. Models using the MMMSE plus PFAQ suggested that urban residence decreased the risk of impaired cognitive function, whereas male gender, older age, vitamin B12 levels and hypertension increased this risk. The variables SF and SF2 and the SF × vitamin B12 interaction were statistically significant (P<0.05). The risk of impaired cognitive function depended on different combinations of SF and vitamin B12 levels. When SF was low, a one-unit increase in SF (1 µg/l) diminished the risk. When SF was elevated, a further increase in SF raised the risk, especially at low vitamin B12 levels.ConclusionsThe relationship between folate, vitamin B12 and impaired cognitive function warrants further study.

Abstract Normal aging can be characterized by a gradual decline in some cognitive functions, such as memory. Memory complaints are common among older adults, and may indicate depression, anxiety, or cognitive decline. Objectives: To investigate the association between memory complaints and age in cognitively unimpaired older adults, and the relationship between memory complaints and memory performance. Methods: Cognitive screening tests as well as memory complaint questionnaires validated for the Brazilian population were used: the Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Memory Complaint Questionnaire (MAC-Q), Memory test of 18 pictures, Forward and Backward Digit Span (WAIS-III). Fifty seven regular members of the SESC social club participated (50 women), having a mean age of 71.4 years, and 4 to 8 years of education - 34 from 4 to 7 years and 23 with 8 years of education. Results: Results revealed no significant association between cognitive complaints and age or cognitive performance. Older participants in this sample did not show worse performance or a higher level of complaints. There was no significant association between age and GDS scores. Conclusions: The studied sample constitutes a particular group of older adults whose participation in activities may be protecting them from cognitive decline, thus highlighting the impact of lifestyle on cognitive performance during the aging process.

Few studies have examined the effects of health literacy on people at risk of developing dementia; its effects on the pathogenesis of subjective cognitive decline (SCD) are particularly unclear. This study aimed to clarify the relationship between health literacy and SCD in a population of healthy community-dwelling older adults. SCD status was assessed using the Cognitive Function domain of the Kihon Checklist (KCL-CF). Health literacy, in turn, was evaluated using the Communicative and Critical Health Literacy (CCHL) scale. Global cognitive function and depressive symptoms were evaluated using the Mini-Mental State Examination (MMSE) and a five-item version of the Geriatric Depression Scale (GDS-5), respectively. Participants who were suspected of having SCD were significantly older than their non-SCD peers, and scored significantly worse on the CCHL, MMSE, and GDS-5. In addition, SCD status was found to be associated with CCHL and GDS-5 scores, as well as age, according to a logistic regression analysis. These findings suggest that low health literacy is linked to SCD morbidity in healthy community-dwelling older adults and should prove useful in the planning of dementia prevention and intervention programs for this population.

Background: Recent studies have shown that long working hours can have adverse consequences on health and possibly trigger biological processes that mediate the relationship between long working hours and cognitive decline. Objective: To investigate whether long working hours and the overall duration such exposure is associated with a decline in cognitive function. Methods: Data obtained during the Korean Longitudinal Study on Aging (n = 2,518) during the period 2006–2018 were used to explore the relationship between long working hours and cognitive decline. Korean version of the Mini-Mental State Examination (K-MMSE) scores were used to evaluate cognitive function. Cox proportional hazard regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs), which were used to evaluate declines in K-MMSE scores over the 12-year study period. Results: Overall HR (95% CI) for a decline in cognitive function in long working hours group was 1.13 (0.73–1.17). When categorized by sex, women with long working hours had an HR (95% CI) of 1.50 (1.05–2.22), K-MMSE scores decreased significantly after working long hours for 5 years (p < 0.01). Conclusion: The study furthers understanding of the effects of long working hours on cognitive decline among female workers. Further research is required to determine the effects of long working hours on cognitive functions.

Abstract Poor oral health, diabetes mellitus (DM), and cognitive impairment are common problems in older adults. Using national surveys, this symposium aims to present new findings regarding the impact of the co-occurrence of DM and poor oral health on cognitive function, cognitive decline, and mortality. This symposium will also cover the topic of dental care use among adult populations in the U.S. Using data from the Health and Retirement Study (HRS) (2006- 2018), the first study shows that adults with both DM and edentulism had the worst cognitive function, followed by those with edentulism alone, and those with DM alone. Using the same HRS data, the second study found that co-occurrence of DM and edentulism had a higher risk of more rapid cognitive decline with advancing age than the presence of each condition alone. The third study used data from the 2006-2016 HRS linked with mortality files, and revealed that the risk of diabetes and edentulism on mortality may vary across racial/ethnic groups. Using the Behavioral Risk Factor Surveillance System survey (2002-2018), the fourth study examined disparities of dental service utilization among racial/ethnic groups (Whites, Hispanics, Blacks, Asians, American Indians or Alaska Natives, and Native Hawaiian or other Pacific Islanders). Age differences in dental services were also compared between older adults and other younger and middle-aged populations. This symposium highlights the role of oral health in improving cognitive health. Policies and programs are needed to increase dental care access, a critical way to help maintain good oral health.

Abstract Background Dementia prevalence is increasing worldwide, and thus, the global impact of cognitive impairment and dementia has become a priority public health issue. This study aimed to assess the patterns of and risk factors for cognitive decline over time in community-dwelling Korean adults aged ≥ 65 years. Methods Older adults with normal cognitive function at baseline in 2006 were evaluated, and changes in their cognitive function were followed over time. The data were obtained from the 2006–2016 Korean Longitudinal Study of Aging. Cognitive function in 2016 was classified based on the Korean-Mini-Mental State Examination score as normal, mild dementia, and moderate and severe dementia. The t-test, ANOVA, and linear mixed models were used to analyse the patterns and risk factors f cognitive decline over time. Results Of the 1,262 participants examined, 752 maintained normal cognitive function, 267 older adults showed a change from normal cognitive function to mild dementia, and 243 older adults showed a decline from normal cognitive function to moderate and severe dementia between 2006 and 2016. There were significant differences in cognitive function over time among the three groups, and these were influenced by age, gender, education level, religion, activities of daily living, instrumental activities of daily living, regular exercise, number of meetings with friends, and depression. The differences have gradually increased over 10 years. Conclusions This study identified the patterns of cognitive decline over time and important factors related to cognitive decline. Individualised interventions such as improving physical function through regular exercise, increasing social activity, and managing depression by early detection and treatment may contribute to maintain cognitive function.

Population aging has recently been an important issue as the number of elderly people is growing worldwide every year, and the extension of social security costs is financially costly. The increase in the number of elderly people with cognitive decline is a serious problem related to the aging of populations. Therefore, it is necessary to consider not only physical care but also cognitive patterns in the future care of older adults. Since food contains a variety of bioactive substances, dietary patterns may help improve age-related cognitive decline. However, the relationship between cognitive function and individual food components remains ambiguous as no clear efficacy or mechanism has been confirmed. Against this background, this review summarizes previous reports on the biological process of cognitive decline in the elderly and the relationship between individual compounds in foods and cognitive function, as well as the role of individual components of food in cognitive function, in the following order: lipids, carotenoids, vitamins, phenolic compounds, amino acids, peptides, and proteins. Based on the research presented in this review, a proper diet that preserves cognitive function has the potential to improve age-related cognitive decline, Alzheimer’s disease, and Parkinson’s disease. Hopefully, this review will help to trigger the development of new foods and technologies that improve aging and cognitive functions and extend the healthy life span.

Abstract Chronic pain and cognitive decline are common age-related conditions affecting a large segment of older populations. Little is known about the pathway of cognitive functioning during the course of pain management in older adults. The current study aimed to examine the association between chronic body pain management and cognitive function over time among Chinese older adults. A total of 792 respondents aged 60 and above from urban and rural households in 28 provinces, 150 counties/districts, and 450 communities were selected from the China Health and Retirement Longitudinal Study (2013–2015). Cognitive function was measured in three domains: episodic memory, mental status, and global cognitive function. Difference-indifferences approach and mixed-effects linear regression models were employed to assess the association between chronic body pain management and cognitive function over time. Scores of mental status were found to decline slower by 0.49 unit (SE = 0.22, p &lt; 0.05) in respondents who received pain management using analgesics, complementary and alternative medicine, or both from 2013 to 2015 after controlling for basic demographic and health confounders. Chronic pain management was associated with slower decline in domain-specific cognitive function, mental status over time. Findings of the study may contribute to understanding the mechanism of change in diverse cognitive abilities attributable to pain symptoms. More research is needed to elucidate the mediating effect of pain on cognitive decline, which could lead to testing of the impact of pain management on cognitive function among older population in both clinical and community settings.

Abstract Evidence suggests that depressive symptoms among older adults were associated with cognitive impairment and affect cognitive decline over time, while physical activity was associated with lower risk of cognitive decline or have positive effect on cognitive function. The purpose of this study is to examine whether physical activity could mediate the effects of depressive symptoms on the cognitive function of older adults. Data from the 2014 Health and Retirement Survey (HRS) of older adults ≥ 60 years (N=9,753) were used. Hierarchical regression was conducted to examine the relationship between depressive symptoms, physical activity, and cognitive function. Mediation analysis was used to examine whether physical activity could mediate the effects of depressive symptoms on cognitive function. Regression results indicated that increased depressive symptoms was associated with poorer cognitive function, while increased moderate and mild physical activity were associated with better cognitive function. Mediation analysis indicated that the direct effect of depressive symptoms on cognitive function was significant. The indirect effect of depressive symptoms on cognitive function mediated by moderate and mild physical activity were also significant. Findings suggest that physical activity could potentially improve the cognitive function of older adults who have depressive symptoms. Moderate and mild physical activity could benefit older adults with depressive symptoms and reduce the risk of cognitive decline. Frail, disabled or chronically ill older adults are less likely to participate in vigorous physical activity, but they could benefit from moderate or mild physical activity and have better cognitive health.
