Background/Aims: Recent studies of cases with mild cognitive impairment (MCI) suggested that besides Alzheimer disease (AD)-related biomarkers, some personality dimensions are associated with progression to AD. To date, there are no studies addressing the psychological determinants of subtle cognitive decline in healthy elderly controls. Methods: 488 community-dwelling healthy controls were assessed with a detailed neuropsychological battery at baseline and an 18-month follow-up. Personality factors and facets were investigated at baseline using the NEO-Personality Inventory-Revised (NEO-PI-R). Upon follow-up, there were 264 stable controls (sCON) and 224 deteriorating controls (dCON). Their personality data were compared to those of the 102 MCI cases using one-way analysis of variance and logistic regression models. Results: Significantly higher scores of Openness factor (as well as Aesthetics, Ideas and Values facets) were found in sCON than in both dCON and MCI cases. The three groups did not differ in the other NEO-PI-R factor and facet scores. Openess factor (and the same facets) was associated with cognitive preservation in healthy controls (OR: 0.72, 95% CI: 0.59, 0.87). Lower scores in the same factor and facets conferred higher risk to have MCI (OR: 0.61, 95% CI: 0.46, 0.79). Conclusion: Higher openness to new experiences and thoughts may be a protective factor against early cognitive decline in brain aging.

ABSTRACTBackground: Apathy, a complex neuropsychiatric syndrome, commonly affects patients with Alzheimer's disease. Prevalence estimates for apathy range widely and are based on cross-sectional data and/or clinic samples. This study examines the relationships between apathy and cognitive and functional declines in non-depressed community-based older adults.Methods: Data on 1,136 community-dwelling adults aged 50 years and older from the Baltimore Epidemiologic Catchment Area (ECA) study, with 1 and 13 years of follow-up, were used. Apathy was assessed with a subscale of items from the General Health Questionnaire. Logistic regression, t-tests, χ2 and Generalized Estimating Equations were used to accomplish the study's objectives.Results: The prevalence of apathy at Wave 1 was 23.7%. Compared to those without, individuals with apathy were on average older, more likely to be female, and have lower Mini-mental State Examination (MMSE) scores and impairments in basic and instrumental functioning at baseline. Apathy was significantly associated with cognitive decline (OR = 1.65, 95% CI = 1.06, 2.60) and declines in instrumental (OR = 4.42; 95% CI = 2.65, 7.38) and basic (OR = 2.74; 95%CI = 1.35, 5.57) function at 1-year follow-up, even after adjustment for baseline age, level of education, race, and depression at follow-up. At 13 years of follow-up, apathetic individuals were not at greater risk for cognitive decline but were twice as likely to have functional decline. Incidence of apathy at 1-year follow up and 13-year follow-up was 22.6% and 29.4%, respectively.Conclusions: These results underline the public health importance of apathy and the need for further population-based studies in this area.

Background: Findings on the associations between anxiety and cognitive decline are mixed and often confounded. Objective: We studied whether anxiety symptoms were associated with the risk of cognitive decline after adequate adjustment of confounding factors. Methods: Our study consists of 2,551 community-dwelling older adults recruited between the ages of 60–64 years and followed up for 12 years in the PATH Through Life cohort study. Anxiety symptoms were measured using the Goldberg Anxiety Scale (GAS; range 0–9). General cognitive function, episodic memory, working memory, verbal intelligence, processing speed, and psychomotor speed were measured. Multilevel analyses were carried out to investigate the association between anxiety symptoms and cognitive decline over 12 years, taking into account confounding variables. Results: We did not find a significant association between baseline anxiety symptoms and cognitive decline over 12 years. Although some associations between anxiety symptoms with psychomotor speed (β= –0.04, 99%CI: –0.08, 0.00) and processing speed (β= –0.27, 99%CI: –0.48, –0.07) were found, these were attenuated after adjusting for depression. We also did not find an association between cumulative anxiety and decline in cognitive performance. Conclusion: In this sample of cognitively healthy men and women aged 60 years and above, anxiety symptoms were not associated with the risk of cognitive decline. Long follow-up study time, appropriate selection of confounding factors, and estimating the effect of cumulative anxiety are important to establish the association between anxiety and cognitive symptoms.

Background: Participation in exercise may be useful for dementia prevention; however, the specific exercise types which may best to reduce the risk of developing cognitive decline have remained unidentified in the literature. Objective: To examine the relationships of specific exercise types with the risk of developing cognitive decline in older women. Methods: This 1- to 2-year population-based cohort study included 687 community-dwelling older Japanese women without disability, neurological disease, dementia, or cognitive impairment assessed as <24 points on the Mini-Mental State Examination (MMSE) at the baseline survey. Developing cognitive decline was defined as a decrease of ≥3 points in the participant’s MMSE score during the follow-up. We classified individuals into participation (≥3 months) and non-participation (<3 months) groups for 17 different exercise types. Log-binominal regression analyses were applied to compare risk ratios and confidence intervals of developing cognitive decline between the two groups. Results: Thirty-nine participants (5.7%) developed cognitive decline during the follow-up period. After adjusting for confounders (age, MMSE score, depressive symptoms, body mass index, heart disease, hypertension, diabetes, smoking, low educational level, and the follow-up period in the baseline survey), those who participated in calisthenics demonstrated a significantly lower risk of developing cognitive decline than those who did not participate in calisthenics. No significant relationships between other exercise types and the risk of developing cognitive decline were found. Conclusion: Participation in calisthenics significantly reduced the risk of cognitive decline in community-dwelling older Japanese women, indicating that calisthenics may be a useful type of exercise for promoting dementia prevention.

Abstract Background In the current study, we aimed to investigate the association of dietary inflammation scores (DIS) and lifestyle inflammation scores (LIS) with the risk of metabolic syndrome (MetS) in a prospective population-based study. Methods A total of 1625 participants without MetS were recruited from among participants of the Tehran Lipid and Glucose Study(2006–2008) and followed a mean of 6.1 years. Dietary data of subjects were collected using a food frequency questionnaire at baseline to determine LIS and DIS. Multivariable logistic regression models, were used to calculate the odds ratio (ORs) and 95 % confidence interval (CI) of MetS across tertiles of DIS and LIS. Results Mean ± SD age of individuals (45.8 % men) was 37.5 ± 13.4 years. Median (25–75 interquartile range) DIS and LIS for all participants was 0.80 (− 2.94, 3.64) and 0.48 (− 0.18, − 0.89), respectively. During the study follow-up, 291 (17.9 %) new cases of MetS were identified. Based on the age and sex-adjusted model, a positive association was found between LIS (OR = 7.56; 95% CI 5.10–11.22, P for trend < 0.001) and risk of MetS, however, the association of DIS and risk of MetS development was not statistically significant (OR = 1.30;95% CI 0.93–1.80, P for trend = 0.127). In the multivariable model, after adjustment for confounding variables, including age, sex, body mass index, physical activity, smoking, and energy intake, the risk of MetS is increased across tertiles of DIS (OR = 1.59; 95% CI 1.09–2.33, P for trend = 0.015) and LIS(OR = 8.38; 95% CI 5.51–12.7, P for trend < 0.001). Conclusions The findings of the current study showed that greater adherence to LIS and DIS, determined to indicate the inflammatory potential of diet and lifestyle, are associated with increased the risk of MetS.

Abstract Background During Covid-19 pandemic, the Italian government adopted restrictive limitations and declared a national lockdown on March 9, which lasted until May 4 and produced dramatic consequences on people’s lives. The aim of our study was to assess the impact of prolonged lockdown on behavioral and psychological symptoms of dementia (BPSD). Methods Between April 30 and June 8, 2020, we interviewed with a telephone-based questionnaire the caregivers of the community-dwelling patients with dementia who had their follow-up visit scheduled from March 9 to May 15 and canceled due to lockdown. Among the information collected, patients’ BPSDs were assessed by the Neuropsychiatric Inventory (NPI). Non-parametric tests to compare differences between NPI scores over time and logistic regression models to explore the impact of different factors on BPSD worsening were performed. Results A total of 109 visits were canceled and 94/109 caregivers completed the interview. Apathy, irritability, agitation and aggression, and depression were the most common neuropsychiatric symptoms experienced by patients both at baseline and during Covid-19 pandemic. Changes in total NPI and caregiver distress scores between baseline and during lockdown, although statistically significant, were overall modest. The logistic regression model failed to determine predictors of BPSD worsening during lockdown. Conclusion This is one of the first studies to investigate the presence of BPSD during SARS-CoV-2 outbreak and related nationwide lockdown, showing only slight, likely not clinically relevant, differences in BPSD burden, concerning mostly agitation and aggression, anxiety, apathy and indifference, and irritability.

We investigated the association between poststroke cognitive impairment and a specific effective network connectivity in the prefrontal–basal ganglia circuit. The resting-state effective connectivity of this circuit was modeled by employing spectral dynamic causal modeling in 11 poststroke patients with cognitive impairment (PSCI), 8 poststroke patients without cognitive impairment (non-PSCI) at baseline and 3-month follow-up, and 28 healthy controls. Our results showed that different neuronal models of effective connectivity in the prefrontal–basal ganglia circuit were observed among healthy controls, non-PSCI, and PSCI patients. Additional connected paths (extra paths) appeared in the neuronal models of stroke patients compared with healthy controls. Moreover, changes were detected in the extra paths of non-PSCI between baseline and 3-month follow-up poststroke, indicating reorganization in the ipsilesional hemisphere and suggesting potential compensatory changes in the contralesional hemisphere. Furthermore, the connectivity strengths of the extra paths from the contralesional ventral anterior nucleus of thalamus to caudate correlated significantly with cognitive scores in non-PSCI and PSCI patients. These suggest that the neuronal model of effective connectivity of the prefrontal–basal ganglia circuit may be sensitive to stroke-induced cognitive decline, and it could be a biomarker for poststroke cognitive impairment 3 months poststroke. Importantly, contralesional brain regions may play an important role in functional compensation of cognitive decline.

Abstract Background Visual impairment (VI) and determinants of poor cardiovascular health are very common in sub-Saharan Africa. However, we do not know whether these determinants are associated to VI among older adults in this region. This study aimed at investigating the association between the determinants of poor cardiovascular health and near VI among older adults living in Congo. Methods Participants were Congolese older adults aged ≥ 65 years included in EPIDEMCA-FU (Epidemiology of Dementia in Central Africa - Follow-up) population-based cohort. Near VI was defined as visual acuity &lt; 20/40 measured at 30 cm. Associations between determinants of poor cardiovascular health collected at baseline and near visual acuity measured at 1 st follow-up were investigated using multivariable logistic regression models. Results Among the 549 participants included, 378 (68.8% [95% Confidence Interval: 64.9%-72.7%]) had near VI. Of the determinants of poor cardiovascular health explored, we found that having high BMI ≥ 25 kg/m 2 (Odds Ratio= 2.15 [95% CI: 1.25–3.68]), diabetes (OR=2.12 [95% CI: 1.06–4.25]) and hypertension (OR=1.65 [95% CI: 1.02–2.64]) were independently associated with near VI. Conclusions Several determinants of poor cardiovascular health were associated to near VI in this population. This study suggests that promoting a good cardiovascular health could represent a target for VI prevention among older adults.

Abstract Objectives Playing analog games may be associated with better cognitive function but, to date, these studies have not had extensive longitudinal follow-up. Our goal was to examine the association between playing games and change in cognitive function from age 11 to age 70, and from age 70 to 79. Method Participants were 1,091 nonclinical, independent, community-dwelling individuals all born in 1936 and residing in Scotland. General cognitive function was assessed at ages 11 and 70, and hierarchical domains were assessed at ages 70, 73, 76, and 79 using a comprehensive cognitive battery of 14 tests. Games playing behaviors were assessed at ages 70 and 76. All models controlled for early life cognitive function, education, social class, sex, activity levels, and health issues. All analyses were preregistered. Results Higher frequency of playing games was associated with higher cognitive function at age 70, controlling for age 11 cognitive function, and the majority of this association could not be explained by control variables. Playing more games was also associated with less general cognitive decline from age 70 to age 79, and in particularly, less decline in memory ability. Increased games playing between 70 and 76 was associated with less decline in cognitive speed. Discussion Playing games were associated with less relative cognitive decline from age 11 to age 70, and less cognitive decline from age 70 to 79. Controlling for age 11 cognitive function and other confounders, these findings suggest that playing more games is linked to reduced lifetime decline in cognitive function.
