We examined features of everyday activities (capacity and frequency) between older adults with and without cognitive impairment over 12 months. Participants aged ≥60 years and at risk for depression were included (n = 260); 26% ( n = 69) had an acquired cognitive impairment at baseline. Cognitive impairment was defined as one standard deviation below norms on the Repeatable Battery for the Assessment of Neuropsychological Status. Features of everyday activities were measured by a computerized adaptive test version of Late-Life Function and Disability Instrument (LLFDI) at six time points (baseline, 6 weeks, 3, 6, 9, 12 months). There were significant between-group differences in activity frequency ( p = .04), but not activity capacity ( p = .05). The group difference in activity frequency exceeded minimal detectable changes (MDC90 = 3.7) and reached moderate clinical meaningfulness (∆ at six time points = 3.7–4.7). Generalized linear mixed models revealed no Group × Time interactions on activity capacity and frequency ( p = .65 and p = .98). Practitioners may assess changes in activity frequency to monitor cognitive status of clients even when there is no loss of activity capacity.

Sources of health disparities such as educational attainment, cardiovascular risk factors, and access to health care affect cognitive impairment among older adults. To examine the extent to which these counteracting changes affect cognitive aging over time among Mexican older adults, we examine how sociodemographic factors, cardiovascular diseases, and their treatment relate to changes in cognitive function of Mexican adults aged 60 and older between 2001 and 2015. Self and proxy respondents were classified as dementia, cognitive impairment no dementia (CIND), and normal cognition. We use logistic regression models to examine the trends in dementia and CIND for men and women aged 60 years or older using pooled national samples of 6822 individuals in 2001 and 10,219 in 2015, and sociodemographic and health variables as covariates. We found higher likelihood of dementia and a lower risk of CIND in 2015 compared to 2001. These results remain after adjusting for sociodemographic factors, cardiovascular diseases, and their treatment. The improvements in educational attainment, treatment of diabetes and hypertension, and better access to health care in 2015 compared to 2001 may not have been enough to counteract the combined effects of aging, rural residence disadvantage, and higher risks of cardiovascular disease among older Mexican adults.

ABSTRACTBackground:The association between disability and depression is complex, with disability well established as a correlate and consequence of late life depression. Studies in community samples report that greater volumes of cerebral white matter hyperintensities (WMHs) seen on brain imaging are linked with functional impairment. These vascular changes are also associated with late life depression, but it is not known if depression is a modifier in the relationship between cerebrovascular changes and functional impairment.Methods:The study sample was 237 older adults diagnosed with major depression and 140 never depressed comparison adults, with both groups assessed at study enrollment. The dependent variable was the number of limitations in basic activities of daily living (ADL), instrumental ADLs, and mobility tasks. The independent variable was the total volume of cerebral white matter lesions or hyperintensities assessed though magnetic resonance imaging.Results:In analyses controlling for age, sex, race, high blood pressure, and cognitive status, a greater volume of WMH was positively associated with the total number of functional limitations as well as the number of mobility limitations among those older adults with late life depression but not among those never depressed, suggesting the association between WMH volume and functional status differs in the presence of late life depression.Conclusions:These findings suggest older patients with both depression and vascular risk factors may be at an increased risk for functional decline, and may benefit from management of both cerebrovascular risk factors and depression.

Abstract Driving cessation is a major life transition in late life, and can affect the quality of social life in older adults. The present study aims to systematically review the literature on how driving cessation affects social participation among older adults in the US. The study selection followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Extant literature published from 1990 to 2019 that examined driving cessation and social participation or social engagement among older adults in the US was searched using eight search engines: PsycINFO, CINAHL, SocIndex, AgeLine, MedLine, Scopus, Transportation Research Board Publication Index, and Cochrane Library. Quantitative studies that met the inclusion criteria were reviewed. The assessment of methodological quality was also conducted for included studies. In total, seven studies met the inclusion criteria. Six of the included studies found significant relationships between driving cessation and at least one domain of social participation, such as volunteering, employment, leisure-time activities, and the frequency of contacts. However, the measures of social participation were inconsistent across studies, which might explain that no effects of driving cessation were found on the structure of social network, such as contacts with friends and extended family. There is a need to assist older adults in successfully transitioning to driving cessation and maintaining the social participation. The overall quality of included studies is moderate based on the assessment of risk of bias and confounding.

Abstract Plasma-based biomarkers of amyloid beta (Aβ), a neuropathological hallmark of Alzheimer’s disease, show promise in predicting cognitive impairment and mapping onto cerebral amyloidosis, but little is known about how midlife plasma Aβ associates with late-life cognitive outcomes. Midlife plasma variants Aβ42 and Aβ40 were measured using a fluorimetric bead-based immunoassay in a subsample of visit 3 ARIC participants (1993-95; n=2585, mean age=59.4±5.2, 57% female, 23% African American). We investigated the relationship between midlife plasma Aβ and late-life mild cognitive impairment (MCI; n=923) and dementia (n=628) diagnosed from 2011-19. Multinomial logistic regressions estimated relative risk ratios (RRR) of MCI, dementia, and death vs normal cognitive status as a function of:(1) Aβ42:Aβ40 ratio, (2) Aβ42 and Aβ40 included as separate terms, and (3) Protected Aβ group (participants with Aβ42≥46 pg/ml and Aβ40 <233 pg/ml). Adjusters included age, sex, education, site-race, and APOE4. Every doubling of midlife plasma Aβ42:Aβ40 up to a threshold of 0.20 was associated with 41% lower risk of developing MCI/dementia in comparison to cognitively normal (RRR=0.59 [95% CI:0.42, 0.82]), with no association for ratio values ≥0.20. Every standard deviation increase in plasma Aβ42 was associated with 17% lower risk of dementia (RRR=0.83 [0.70, 0.99]), whereas every standard deviation increase in plasma Aβ40 was associated with 16% higher risk of MCI (RRR=1.16 [1.02, 1.31]). The protected midlife plasma Aβ group had 86% lower risk of late-life dementia vs all others (RRR=0.14 [0.04, 0.47]). Early measurement of plasma Aβ may prove an accessible and effective population screener for future cognitive impairment.

ABSTRACTBackground:Previous studies suggest that there is a strong association between depression and cognitive decline, and that concurrent depressive symptoms in MCI patients could contribute to a difference in neurocognitive characteristics compared to MCI patients without depression. The authors tried to compare neurocognitive functions between MCI patients with and without depression by analyzing the results of neuropsychological tests.Methods:Participants included 153 MCI patients. Based on the diagnosis of major depressive disorder, the participants were divided into two groups: depressed MCI (MCI/D+) versus non-depressed MCI (MCI/D−). The general cognitive and functional statuses of participants were evaluated. And a subset of various neuropsychological tests was presented to participants. Demographic and clinical data were analyzed using Student t-test or χ2 test.Results:A total of 153 participants were divided into two groups: 94 MCI/D+ patients and 59 MCI/D− patients. Age, sex, and years of education were not significantly different between the two groups. There were no significant differences in general cognitive status between MCI/D+ and MCI/D− patients, but MCI/D+ participants showed significantly reduced performance in the six subtests (Contrasting Program, Go-no-go task, Fist-edge-palm task, Constructional Praxis, Memory Recall, TMT-A) compared with MCI/D− patients.Conclusions:There were significantly greater deficits in neurocognitive functions including verbal memory, executive function, attention/processing speed, and visual memory in MCI/D+ participants compared to MCI/D−. Once the biological mechanism is identified, distinct approaches in treatment or prevention will be determined.

Cognitive Complaint

Most old adults receive their health care from their primary care practitioner; as a consequence, as the population ages, the manifestations and complications of cognitive impairment and dementia impose a growing burden on providers of primary care. Current guidelines do not recommend routine cognitive screening for older persons by primary care physicians, although the vast majority recommend a cognitive status assessment and neurological examination for subjects with a cognitive complaint. Also, no clinical practice guidelines recommend interventions in older adults with cognitive impairment in primary care settings. However, primary care physicians need to conduct a review of risks and protective factors associated with cognitive decline and organize interventions to improve or maintain cognitive function. Recent epidemiological studies have indicated numerous associations between lifestyle-related risk factors and incidental cognitive impairment. The development of biomarkers could also help in diagnosis, prognosis, selection for clinical trials, and objective assessment of therapeutic responses. Interventions aimed at cognitive impairment prevention should be pragmatic and easy to implement on a large scale in different health care systems, without generating high additional costs or burden on participants, medical and social care teams.

Aortic Stiffening

Introduction: Stiffening of the aorta is associated with greater pulse pressure and transmission of pulsatile energy into the cerebral circulation, which can increase susceptibility to microvascular damage in the brain. We tested the hypothesis that higher aortic stiffness measured in late-life is associated with a greater prevalence odds of dementia measured ~5 years later. Methods: Dementia-free ARIC-NCS participants (n=4753; mean age: 75 years; 42% male; 21% black) with measures of aortic stiffness at the visit 5 (2011-2013) examination were included. Aortic stiffness was measured by carotid-femoral pulse wave velocity (cfPWV) using the VP-1000 Plus device (Omron Co., Japan) and modeled as continuous (per standard deviation (SD)), categorical into distribution-based quartiles, and as elevated vs. non-elevated cfPWV according to the upper 25 th percentile (13.34 m/s). Cognitive status (normal/mild cognitive impairment (MCI)/dementia) was ascertained at the visit 5 and 6 (2016-2017) examinations with expert review by an adjudication committee of in-person cognitive testing. A multivariable logistic regression model estimated the adjusted association of cfPWV with 5-year odds of dementia. Results: Among dementia-free participants, a 1 SD higher cfPWV was associated with a greater odds of dementia (Odds Ratio (OR): 1.19 (95% Confidence Interval (CI): 1.03, 1.39). Elevated cfPWV (upper 25 th percentile) was also associated with a greater odds of dementia (OR: 1.54, 95% CI: 1.08, 2.19) in this sample. This association was stronger among participants who were cognitively normal at visit 5 (n=3758, Table): the multivariable-adjusted OR of dementia = 2.16 (95% CI: 1.35, 3.47) for elevated vs. non-elevated cfPWV. The risk of dementia among those with baseline MCI (n=955) was not associated with cfPWV levels. Results were robust to adjustment for vascular risk factors. Conclusions: Among older adults, especially when MCI is not present, greater central aortic stiffness is associated with dementia risk.

Famine Exposure

Previous studies on the Chinese famine suggested long-term effects of early-life famine exposure on health conditions. This study aims to investigate the association between exposure to the Chinese famine of 1959–1961 at different early-life stages and the risk of cognitive decline in adulthood. A total of 6417 adults born between 1952 and 1964 in the 2015 survey data of China Health and Retirement Longitudinal Study were included in this study. Cognitive performance was estimated through a series of comprehensive neuropsychological tests, including the Telephone Interview of Cognitive Status (TICS-10), word recall, and pentagon drawing. Multiple generalized linear model (GLM) was employed to detect the association between multi-stage early-life famine exposure and late-life cognitive performance. Compared with the unexposed group, respondents exposed to famine in the fetal period performed worse in the TICS (difference −0.52, 95% confidence interval (CI): −0.93 to −0.10), word recall (difference −0.46, 95% CI: −0.74 to −0.19), and general cognition (difference −1.05, 95% CI: −1.64 to −0.47). Furthermore, we also found negative effects of famine exposure on performance of word recall and pentagon drawing in the early (word recall difference −0.56, 95% CI: −1.00 to −0.11; pentagon drawing difference −0.76, 95% CI: −1.40 to −0.12), mid (word recall difference −0.46, 95% CI: −0.81 to −0.11; pentagon drawing difference −0.66, 95% CI: −1.16 to −0.16), and late (word recall difference −0.30, 95% CI: −0.55 to −0.04; pentagon drawing difference −0.75, 95% CI: −1.13 to −0.37) childhood-exposed groups. Early-life famine exposure in different stages is positively associated with late-life cognitive decline. Fetal famine exposure might affect the overall cognitive status in adulthood, and childhood famine exposure has potential adverse effects on visuospatial episodic memory.
