Abstract Background: Studies have been investigating the effect of financial difficulties on cognitive function especially in the US and Australia. However, there is still a discrepancy regarding the results. This study aims to estimate the effect of financial difficulties on cognitive function in a Japanese elderly population sample. It is rewarding to focus on the Japanese setting, which has the highest proportion of elderly in the world. Method: This study uses a longitudinal panel dataset which include randomly selected elderly Japanese citizens aged 60 and over; the National Survey of the Japanese Elderly. It is a panel dataset containing income and cognitive function. It is ideal dataset to capture the probability of onset of cognitive impairment as it focuses on the elderly. We estimate the effect of participants’ equivalent income on the probability of onset of cognitive impairment at a following survey point using random-effect probit model. Result: The first main result is there is a significant negative effect from financial difficulties on cognitive function. The results indicate that when participants’ equivalent income drops by 1%, they are 2.2% more likely to develop cognitive impairment. The second result is that this negative effect is heterogeneous, depending on their income level. Specifically, this negative effect is observed only at low income level, but not at high income level. That is, the deteriorating effect by impoverishment would be severe when the financially needy people faced income drops. Discussion: Income support plays an important role in improving recipients’ cognitive function, especially among the poor.

Background: Obesity is a potentially modifiable risk factor for cognitive impairment. However, sex-specific relationships between obesity and cognitive impairment in late life remain unclear.Objective: We aimed to assess sex differences in the association between various obesity parameters and cognitive impairment in a low-income elderly population in rural China.Methods: A population-based cross-sectional study was conducted to collect basic information from elderly residents aged 60 years and older from April 2014 to August 2014 in rural areas of Tianjin, China. Obesity parameters, including body mass index (BMI) and waist circumference (WC), and Mini Mental State Examination scores were measured, and the relationships between these variables were assessed.Results: A total of 1,081 residents with a mean age of 67.70 years were enrolled in this study. After adjusting for age, educational attainment, smoking status, drinking status, physical exercise participation, and the presence of diabetes and hyperlipidemia, blood pressure group; a high BMI was found to be associated with an increased prevalence of cognitive impairment in elderly women. Each 1-unit increase in BMI was associated with a 5.9% increase in the prevalence of cognitive impairment. WC was related to the prevalence of cognitive impairment in elderly men, and each 1-cm increase in WC was associated with a 4.0% decrease in the prevalence of cognitive impairment. However, there were no significant associations between WC and cognitive function in women or between BMI and cognitive impairment in men.Conclusion: A greater WC was positively associated with better cognitive function in low-income elderly men in rural China, whereas a higher BMI was associated with an increased risk of cognitive impairment in elderly women, independent of sociodemographic, lifestyle, and health-related comorbid factors. Our results suggest weight management of elderly women in rural China may have cognitive benefits. However, randomized controlled trials would be needed to confirm causality.

Functional incapacity and cognitive impairment are conditions related to the process of human aging. Cognitive impairment is considered an important predicitve factor for functional impairment in elderly populations. This cross-sectional study analyzes the association between cognitive performance and functional capacity in an elderly population sample in Natal, Brazil. A total of 213 elderly persons were assessed by the BOAS Multidimensional Questionnaire (Brazil Old Age Schedule) and the Mini-Mental State Examination (MMSE). The results of multivariate analysis and linear regression showed that age and schooling level are factors associated with cognitive performance in the elderly of this study. The final explicative model, elaborated by logistic regression, found that cognitive performance was the only predicitve variable of functional incapacity for the activities of daily living even when adjusted for sociodemographic variables.

Abstract Background Cognitive decline is common in older adults. Similarly, the prevalence of renal dysfunction is also increased in the elderly population. We conducted this study to clarify the relationship between renal dysfunction and decline of cognitive function in community-dwelling elderly population. Methods A cross-sectional analysis was performed using data from the Korean Frailty and Aging Cohort Study, a nationwide cohort study. Total 2847 (1333 men, 1514 women) eligible participants were enrolled for this study. The estimated glomerular filtration rate (eGFR, mL/min/1.73m2) was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation. Global cognitive function was assessed with the Mini-mental State Examination-Korean version. Other domains of cognitive function were tested with the Consortium to Establish a Registry for Alzheimer’s disease and the Frontal Assessment Battery. Results The mean age of all participants was 76.0 ± 3.9 years and eGFR (all in mL/min/1.73 m2) was 77.5 ± 14.3. And the mean eGFR was 91.7 ± 3.2 in quartile 1, 84.9 ± 1.8 in quartile 2, 76.1 ± 3.7 in quartile 3, and 57.2 ± 10.8 in quartile 4. In baseline characteristics, participants with lower eGFR tend to have lower cognitive function scores than participant with higher eGFR. In linear regression analysis, eGFR was correlated with the word list memory (β = 0.53, P = 0.005), word list recall (β = 0.86, P < 0.001), and word list recognition (β = 0.43, P = 0.030) after adjustment of confounding variables. Moreover, after multivariate adjustment the association with cognitive impairment in quartile 2 was stronger (adjusted OR: 1.535, 95% CI: 1.111–2.120, P = 0.009), and the ORs of cognitive impairment were 1.501 (95% CI: 1.084–2.079, P = 0.014) in quartile 3 and 1.423 (95% CI: 1.022–1.983, P = 0.037) in quartile 4. Conclusion In older adults, the immediate, recent memory, and recognition domains were significantly related to renal function. Also, the mild renal dysfunction was independently associated with impairment of global cognitive function. These results suggest that the early stages of renal dysfunction could be an effective target to prevent worsening of cognitive impairment. Therefore, regular monitoring and early detection of mild renal dysfunction in elderly population might be needed.

Each year in the world, especially in Indonesia, many elderly people exposed to higher risk of dementia due to an increased number of the elderly population and the incidence of mild cognitive impairment in the elderly. The aim of this study is to find out what factors are related with cognitive function in the elderly population. The study used analytic method with cross sectional study design. Subjects were 60 elderly people; male or female ≥ 60 years old. Data were analysed with Chi Square Test (α = 0.05). Cognitive function was measured by MMSE test. The result were found a significant relation between age and cognitive function ( p = 0.014), level of education and cognitive function (p value = 0.000), physical activity and cognitive function (p value = 0.003), cognitive activity and cognitive function (p value = 0.002), and social interaction and cognitive function (p value = 0.000). Gender variable did not have relation with cognitive function (p value = 0.343). This study conclude that there was a relation between age, education level, physical activity, cognitive activity and social interaction with cognitive function in the elderly population. There was no relation between gender and cognitive function in the elderly population.Keywords: cognitive function, cognitive impairment, elderly, MMSE

Modifiable Factors

Background: Identification of early modifiable factors is crucial to delay or prevent the development of cognitive impairment and reduce the social and economic burden.Objective: This study aimed to examine the longitudinal associations of childhood neighborhood quality (CNQ) with the risk of later-life cognitive dysfunction and the role of body mass index (BMI) in this association.Methods: A total of 8,289 community-dwelling middle-aged and elderly population from wave 2011, wave 2013, and wave 2015 of the China Health and Retirement Longitudinal Study (CHARLS) were included. Cognitive function and CNQ were measured by standardized questionnaires. Multilevel linear regression models were used to estimate the associations of CNQ and cognitive function. The interactions of BMI with CNQ in the progress of cognitive function were also estimated.Results: The participants with higher CNQ had a significantly low risk of cognitive impairment than those with lower CNQ score (β = 0.067, 95% CI: 0.031, 0.103), and the results remained similar (β = 0.039, 95% CI: 0.004, 0.075) after controlling other confounding variables. Furthermore, there was an interaction between BMI with CNQ score (P &lt; 0.001) for the risk of cognitive impairment. In BMI-stratified analysis, we found that the association of CNQ and cognitive function was not statistically significant in overweight or obese population (β = 0.019, 95% CI: −0.032, 0.070), but was statistically significant in people with lower BMI (β = 0.059, 95% CI: 0.010, 0.107).Conclusions: Higher CNQ score is significantly associated with the lower risk of cognitive dysfunction in adulthood. BMI may moderate the associations of CNQ with the risk of cognitive function.

Objectives. In this study, we aimed to conduct a 6-year follow-up and acquire a large sample dataset to analyze the most important demographic factors and cognitive function scale variables associated with mild cognitive impairment (MCI) progression for an elderly cohort (age ≥ 60 years old). Patients and Methods. We analyzed the subjects who had participated in a survey in 2011 and were successfully contacted in the later survey in 2017. For each subject, the basic demographic information was recorded, including sex, age, education level, marital status, working status, income level, and physical mental illness history. Cognitive assessments were performed using the following scales if possible: (1) the mini-mental state examination (MMSE) scale, (2) Montreal cognitive assessment (MoCA), (3) the clinical dementia rating (CDR) scale, and (4) Hamilton Depression Scale (HAMD-17). Results. The progression outcomes were different between sexes, among age brackets, education degrees, occupations types, and income levels; different progression groups had distinct children numbers (p<0.001), heights (p<0.05), and body weights (p<0.01); the positive ends six years later were positively related to better performance in the MoCA and MMSE scales (progressed vs stable p<0.01). Moreover, we constructed some indicators using age, MoCA, and MMSE scores, which showed an efficiency in predicting the progression outcomes. Conclusions. In conclusion, the MCI progression outcomes were associated with sex, age, education degrees, occupations types, income level, children number, height, and weight. MoCA and MMSE scales are supporting tools to predict the progression outcomes, especially combined with the demographic data.

Goal. To review the literature on the problem of the influence of variability of blood pressure on the cognitive function of patients with dyscirculatory encephalopathy after suffering ischemic stroke on the background of hypertension. Research Methods: Bibliosemantic, Comparative and Systemic Results. In the Recommendations of the European Society of Cardiologists / European Society for Hypertension (European Approach). Society for Cardiology / European Society of Hypertension - ESC / ESH) 2018 for the treatment of hypertension emphasized that the study of cognitive function (CF) should be mandatory in the list of methods of examination of patients to detect the damage of target organs caused by hypertension, in order refinement of stratification of risk of cardiovascular events, namely stroke (Williams B. et al., 2018). Cognitive impairment in patients with cardiovascular disease is known to be one of the earliest and most sensitive indicators of cerebral vascular injury and is a consequence of chronic cerebral ischemia and / or recurrent acute cerebral circulation disorders. It is proved that the variability of blood pressure has a negative effect on cerebral circulation, is a predictor of chronic brain ischemia, which can result in the appearance or deepening of cognitive impairment. In the ASCOT study on the prognostic significance of variability in daily monitoring of blood pressure, intracutaneous variability, and long-term variability, it was found that visit-to-visit variability is a strong predictor of stroke and coronary events, not independent of the level. Conclusions. Analysis of the literature on this problem has shown the negative effect of blood pressure variability on the course of chronic brain ischemia, which exacerbates cognitive and emotional-volitional disorders in patients with hypertensive dyscirculatory encephalopathy. The peculiarities of the effect of blood pressure variability on CF in patients with brain stroke are poorly understood and need further investigation.

Abstract Background: Malnutrition is one of the health problems in the elderly population, which increases the risk of poor clinical outcomes. The purpose of this investigation was to evaluate the nutritional status and cognitive function of an elderly Chinese population, to explore the association between malnutrition and cognitive condition as well as the cognitive domain.Methods: A cross-sectional study was conducted in 2365 participants aged 60 years or above from January 2013 to September 2019. We used the Mini Nutritional Assessment Short Form (MNA-SF), and the Mini Mental State Examination (MMSE) to assess the impact of malnutrition on cognitive function. Nutrition-associated factors were analyzed.Results: 33.45% of the participants were identified as malnutrition risk and 5.54% were malnourished, while 36.74% had cognitive impairments. 48.63% had nutritional deficits and 53.65% had cognitive impairment in those over 80 years old. Malnutrition is associated with global cognition (ρ= 0.349, P < 0.0001) and the cognitive domain particularly in orientation (ρ= 0.343, P < 0.0001). The impact was extended to attention and calculation (ρ=0.310, P < 0.0001) as well as language (ρ= 0.302, P < 0.0001) of those over 80 years of age. Malnutrition is an independent risk factor for cognitive impairment after adjusting for other variables (OR=2.004, 95% CI: 1.621-2.479).Conclusion: The prevalence of malnutrition and cognitive impairment was relatively high and increased with age. Malnutrition leads to cognitive decline and disorientation, and also contributes to attention problems, calculation problem and language impairment in the oldest old. Thus, clinicians should assess the nutritional and cognitive status of the elderly regularly to the early dictation and timely intervention.

Critical Challenge

Strategies to improve cognitive aging are highly needed. Among those, promotion of exercise and physical activity appears as one of the most attractive and beneficial intervention. Indeed, results from basic and clinical studies suggest that exercise and physical activity have positive effects on cognition in older persons without cognitive impairment, as well as in those with dementia. Despite inconsistent results, aerobic exercise appears to have the strongest potential to enhance cognition. However, even limited periods of walking (45 minutes, three times a week, over a 6-month period) have also been shown to enhance cognition, particularly executive functions. Changing long-term lifestyle habits in these older persons remains a critical challenge and attractive programs susceptible to gain adherence are needed to succeed in achieving improved cognitive aging.
