Hypertension, inflammation and oxidative stress are important factors in the development of cognitive impairment. Our previous study demonstrated that tart cherry juice can lower systolic blood pressure (BP) and improve inflammatory and oxidative stress status in older adults. As part of our previous trial, we explored whether daily consumption of tart cherry juice would improve cognitive abilities. In this randomized controlled trial, 37 adults between the ages of 65-80 with normal cognitive function were recruited and randomly assigned to consume two cups of Montmorency tart cherry juice for 12 weeks. Subjective memory and objective cognitive performance were assessed at baseline and after the 12-week juice supplementation using a validated subjective memory questionnaire and a standardized battery of tests. Daily caloric intake and physical activity levels were assessed throughout the study period. After the intervention, participants in the tart cherry group had higher contentment with memory scores (mean difference of 2.7; 95% CI: 1.2 to 4.2; p = 0.02), lowered their scores of movement time (mean difference of -10.4; 95% CI: -13.4 to -7.5; p = 0.03) as well as performed better on the paired associates learning task (mean difference of -8.5; 95% CI: -12.5 to -4.5; p = 0.02) compared to the control group. The within-group analysis showed that the visual sustained attention (p < 0.0001) and spatial working memory (p = 0.06) improved after the 12-week consumption of tart cherry juice compared with corresponding baseline values. Daily tart cherry juice consumption may improve cognitive abilities. This may be through anti-oxidative and anti-inflammatory properties of tart cherry and its ability to lower BP. Further research is needed to confirm these findings.

Objectives: The purpose of this study was to determine whether stability and change in cognitive status are associated with sociodemographic characteristics and health function., Design: Secondary analysis of data., Setting: Baltimore Study of Black Aging-Patterns of Cognitive Aging., Participants: Community-dwelling black adults (N = 407; mean age 68.6 ± 9.1)., Measurements: Baseline (n = 602) and 33-month follow-up (n = 450) assessments of cognition, health, and psychosocial function., Results: For the present analyses, participants were grouped as being cognitively normal (n = 249), having stable mild cognitive impairment (MCI) (n = 32), or being MCI converters (n = 72; normal at baseline, MCI at follow-up) or reverters (n = 54; MCI at baseline, normal at follow-up). Multivariate analysis of variance showed that the groups differed significantly in education and lung function (P < .010). Post hoc analyses indicated that converters had fewer years of education than the other groups, whereas those who were cognitively normal had better lung function than converters and reverters (P < .050)., Conclusion: These results suggest that education and lung health are associated with patterns of cognitive status change and stability. Future research should account for sociodemographic and health factors when examining stability of cognitive status classifications., (© 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.)

Objective: Poor diet quality contributes to morbidity, including poor brain health outcomes such as cognitive decline and dementia. African Americans and individuals living in poverty may be at greater risk for cognitive decrements from poor diet quality., Design: Cross-sectional., Setting: Baltimore, MD, USA., Subjects: Participants were 2090 African Americans and Whites (57 % female, mean age=47·9 years) who completed two 24 h dietary recalls. We examined cognitive performance and potential interactions of diet quality with race and poverty status using baseline data from the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. Healthy Eating Index-2010 (HEI-2010) scores were calculated and interpreted using federal guidelines. A neurocognitive test battery was administered to evaluate cognitive function over several domains., Results: Linear regression analyses showed that lower HEI-2010 scores were associated with poorer verbal learning and memory (P<0·05) after adjustment for covariates. Diet quality within the sample was poor. Significant interactions of HEI-2010 and poverty status (all P<0·05) indicated that higher diet quality was associated with higher performance on tests of attention and cognitive flexibility, visuospatial ability and perceptual speed among those below the poverty line. No significant race interactions emerged. Higher diet quality was associated with better performance on two measures of verbal learning and memory, irrespective of race and poverty status., Conclusions: Findings suggest that diet quality and cognitive function are likely related at the population level. Future research is needed to determine whether the association is clinically significant.

The objectives of the study were to examine whether measures of total obesity (body mass index [BMI]) and central obesity (waist circumference [WC] and waist-to-hip ratio [WHR]) are associated with cognitive function in African Americans, and whether sex moderates these associations. A sample of 194 African Americans, with a mean age of 58.97 years, completed a battery of cognitive tests and a self-reported health questionnaire. Height, weight, waist and hip circumference, and blood pressure were assessed. Linear regression analyses were run. Results suggested lower performance on measures of verbal fluency and complex attention/cognitive flexibility was accounted for by higher levels of central adiposity. Among men, higher WHR was more strongly related to complex attention/cognitive flexibility performance, but for women, WC was a salient predictor. Higher BMI was associated with poorer verbal memory performance among men, but poorer nonverbal memory performance among women. Findings suggest a need for healthy lifestyle interventions for African Americans to maintain healthy weight and cognitive function., (© The Author 2015. Published by Oxford University Press.

Objective The purpose of the current study is to examine the association between subjective memory complaints and sleep (quantity and quality) in African American older adults. Method Participants from the Baltimore Study of Black Aging (BSBA; n = 351; mean age = 71.99) completed a self-report sleep scale, subjective memory complaint scale, global cognitive status measure, and demographic questionnaire. Results Worse overall sleep quality was significantly associated with subjective reports of difficulty recalling the placement of objects, recalling specific facts from reading materials, and worse memory currently compared to the past. Specific sleep parameters (e.g. longer sleep latency and shorter sleep duration) were associated with negative appraisals of participants' ability to do specific tasks involving memory (e.g. difficulty recalling placement of objects). Participants classified as poor sleepers (Pittsburgh Sleep Quality Index [PSQI] total score > 5) were more likely to report worse memory now compared to the past than participants classified as good sleepers (PSQI total score ≤ 5). Conclusions Evaluation of sleep may be warranted when older adults, particularly African Americans, communicate concerns regarding their memory. Insufficient sleep may be a useful marker of acute daytime dysfunction and, perhaps, cognitive decline. Given memory problems are the hallmark of dementia, our findings support further evaluation of whether poor sleep can aid in the diagnosis of cognitive impairment. [ABSTRACT FROM AUTHOR]

Aims and objectives The aims of the current study were to (i) assess older people's awareness of the association between CVD risk factors and cognitive function; and (ii) examine whether awareness varies as a function of demographic factors. Background Cardiovascular disease ( CVD) risk factors have been linked to subtle deficits in cognitive function. CVD risk factors increase the risk of cognitive decline and dementia. The association between cardiovascular disease ( CVD) risk factors and cognitive decrements has been well documented among older people; however, we are unaware of any studies that have measured older people's awareness of this relationship in an effort to assess educational needs. Design A descriptive, cross-sectional survey design was employed. Methods Community-based older adults aged 60 and older completed a survey that assessed their knowledge of the association between CVD risk factors and cognitive function. Results One hundred fifty older adults, with a mean age of 72.88 years, completed the survey. Results showed that over 75% of the sample was aware that CVD risk factors affect cognitive function. White older adults and older adults with greater perceived financial well-being tended to be more aware of these relationships than non-White participants with less perceived financial well-being. Conclusions Results suggest that many, but not all older people have awareness of this relationship. As such, there is a need for increased education about the cognitive effects of CVD risk factors, particularly among older people who are already at risk for developing CVD and those with lesser financial well-being. Implications for Practice Appropriate educational strategies can expose older patients to the importance of healthy lifestyle and self-care to maintain cognitive function. Nurses can incorporate education into care by identifying patients that would benefit from tailored interventions and providing information to at-risk patients about how to maintain their cognitive function through management of specific CVD risk factors.
