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.

The Relationship

The present study examined the relation between cognitive performance and social networking in older adults from Canada and Greece. The two groups were matched on age, gender, education level, and MMSE scores. Participants reported the amount of both off-line and online networking, as well as the social support received in these contexts. Immediate and delayed recall, speed of processing, and executive functioning were also assessed. Online networking was associated with executive functioning. Interestingly, country context didn’t moderate the relationship, despite differences observed between Greeks and Canadians in executive functioning and online networking. Our findings suggest that online social participation could serve both as a source of social support and as cognitive training, benefiting older adults’ cognitive vitality. The findings are discussed in relation to the characteristics of the specific countries, stressing the need to explore the effects of online social networking and participation on cognitive function in the aging population.

Abstract As the number of older adults increases, increased prevalence of cognitive and sensory impairments pose growing public health challenges. Research on the relationship between hearing impairment and cognition, however, is minimal and has yielded mixed results, with some studies finding that hearing impairment is associated with cognitive decline, and others reporting that the association is weak or non-existent. Most of this research has been conducted outside of the U.S., and the few U.S.-based longitudinal studies have relied mostly on small, non-representative samples involving short follow-up periods. Further, despite known gendered patterns in cognitive and hearing impairments, no studies to date have examined whether the relationship between the two varies by gender. Our study addresses these weaknesses in the literature by utilizing nine waves of the Health and Retirement Study (1998-2014; n=14,169), a large, nationally representative, longitudinal study that facilitates examination of long-term interrelationships between hearing and cognitive impairments. In this study, we use autoregressive latent trajectory (ALT) methods to model: 1) the relationship between hearing impairment and cognitive decline, and 2) sex differences in the relationship. ALT models enable us to determine whether hearing impairment and cognitive impairment are associated, net of their common tendency simply to co-trend with age. Results indicate that hearing and cognitive impairments are strongly interrelated processes that trend together over time. Moreover, hearing impairment has an increasing impact on cognitive impairment across age while the effect of cognitive impairment on hearing impairment levels out over time. Sex differences in these patterns are discussed.

Abstract Studies suggest that depression is closely linked to hearing impairment, which is highly prevalent among older adults in the United States. There is evidence that social engagement may be impacted by hearing impairment in older adults. However, there is relatively little research on these associations among Chinese older adults. This study examines the relationships between hearing impairment, social activities, and depressive symptoms among older adults in China. Using nationally representative data from the China Health and Retirement Longitudinal Study 2011, we conducted cross-sectional analysis on adults age 60 years and older (n=10,994). Depressive symptoms were assessed by the 10-item Center for Epidemiologic Studies Depression scale and we considered self-reported hearing status (if participants wear a hearing aid and how they would rate their hearing), and social activities (i.e., volunteering, dancing, attending courses, etc.). Models were controlled for age, gender, education, and other covariates. Descriptive analysis showed that 9% of older adults experienced hearing impairment. Multiple linear regression analyses revealed that hearing impairment was positively associated with depressive symptoms among older Chinese adults (β=1.32, p<.001). Social activities were found to partially mediate the relationship between hearing status and depressive symptoms. Respondents with hearing impairment were less likely to engage in social activities (OR=.78, p<.01) and those who did not participate in social activities reported more depressive symptoms (β=1.28, p<.001). These findings suggest that Chinese older adults experiencing hearing loss are at greater risk of depression and that social activities play an important role in the relationship between hearing status and depression.

The Relationship

Long-term supplementation with folic acid may improve cognitive performance in older individuals. The relationship between folate status and cognitive performance might be mediated by changes in methylation capacity, as methylation reactions are important for normal functioning of the brain. Although aberrant DNA methylation has been implicated in neurodevelopmental disorders, the relationship between DNA methylation status and non-pathological cognitive functioning in human subjects has not yet been investigated. The present study investigated the associations between global DNA methylation and key domains of cognitive functioning in healthy older adults. Global DNA methylation, defined as the percentage of methylated cytosine to total cytosine, was measured in leucocytes by liquid chromatography–MS/MS, in 215 men and women, aged 50–70 years, who participated in the Folic Acid and Carotid Intima-Media Thickness (FACIT) study (clinical trial registration number NCT00110604). Cognitive performance was assessed by means of the Visual Verbal Word Learning Task, the Stroop Colour-Word Interference Test, the Concept Shifting Test, the Letter–Digit Substitution Test and the Verbal Fluency Test. Using hierarchical linear regression analyses adjusted for age, sex, level of education, alcohol consumption, smoking status, physical activity, erythrocyte folate concentration and 5,10-methylenetetrahydrofolate reductase 677 C → T genotype, we found that global DNA methylation was not related to cognitive performance on any of the domains measured. The present study results do not support the hypothesis that global DNA methylation, as measured in leucocytes, might be associated with cognitive functioning in healthy older individuals.

This study examined the influence of insulin resistance and inflammation on the association between body composition and cognitive performance in older adults, aged 60–69 and aged 70 and older. Subjects included 1127 adults from NHANES 1999–2002. Body composition was categorized based on measurements of muscle mass and waist circumference as sarcopenic nonobese, nonsarcopenic obese, sarcopenic obese, and normal. Using OLS regression models, our findings suggest body composition is not associated with cognitive functioning in adults ages 60–69; however, for adults aged 70 and over, sarcopenia and obesity, either independently or concurrently, were associated with worse cognitive functioning relative to non-sarcopenic non-obese older adults. Furthermore, insulin resistance accounted for a significant proportion of the relationship between cognitive performance and obesity, with or without sarcopenia. Additionally, although high CRP was significantly associated with poorer cognitive functioning in adults ages 60–69, it did not influence the association between body composition and cognitive performance. This study provides evidence that age-related physiological maladaptations, such as metabolic deregulation, which are associated with abdominal fat, may simultaneously contribute to lower cognition and muscle mass, reflecting a degradation of multiple physiological systems.

Abstract Cognitive health has emerged as an important public health concern for America’s aging population. Type 2 Diabetes (T2D) may be associated with an exacerbated decline in cognitive performance. This study aimed to examine the relationship between T2D control and cognitive performance in older adults (≥60 years) using the 2013-2014 National Health and Nutrition Examination Surveys. Participants who completed the following cognitive assessments were included: 1) Consortium to Establish a Registry for Alzheimer’s Disease Word List (CERAD-WL), 2) Animal Fluency (AF), 3) Digit Symbol Substitution Test (DSST) (higher scores associated with better cognition). Participants were stratified by four groups: no T2D (N=557), treated/controlled T2D (controlled; N=41), treated/uncontrolled T2D (uncontrolled; N=120), untreated T2D (N=86), based on self-reported T2D treatment, fasting plasma glucose, and hemoglobin A1c. Logistic regression was used to examine the relationship between T2D control and cognition. We observed that those with uncontrolled and untreated T2D each had ~15% lower DSST than those with no T2D (P<0.01). CERAD-WL and AF were similar across all groups. Unadjusted analyses showed that individuals with 1) lower CERAD-WL were more likely to have controlled and untreated T2D, 2) lower AF were more likely to have controlled and uncontrolled T2D, and 3) lower DSST were more likely to have uncontrolled and untreated T2D (P’s<0.05). After adjusting for significant demographics and cardiovascular risk factors, only having uncontrolled T2D was associated with lower DSST (β=-3.164, P=0.04). These data indicate the need for longitudinal studies to further explore dynamic relationship and causal pathway between T2D control and cognitive impairment.

Abstract Cognitive health is a rising public health concern in the U.S. Currently, approximately 5.7 million older adults suffer from Alzheimer’s disease (AD), and by the year 2050 this number is expected to increase to 14 million. Subjective memory complaints (SMC) are shown to be an early indicator of cognitive decline, and accordingly included as a clinical criterion for diagnoses of MCI, an indicator of pre-dementia states, and a research criterion for AD diagnoses. Among older adults, depressive symptoms hinder the accuracy of memory self-ratings. However, there has yet to be consensus regarding the nature of how depressive symptoms may condition the relationship between SMC and cognitive performance. The aims of the present study are to both investigate whether SMC is related to episodic memory and to determine whether depressive symptoms act as a moderator for the relationship between SMC and episodic memory among older adults. This research used nationally representative sample of 8,123 older adults aged 65 and older who completed the Leave Behind Questionnaire in the 2012 and 2014 waves of the Health and Retirement Study. Linear regression was performed and results showed that there was a significant main effect of SMC on episodic memory performance, in that older adults with increased SMC have worse episodic memory. There was also a significant moderating effect of depressive symptoms, in that depressive symptoms cause older adults to underestimate their memory abilities. In order to use SMC as a tool for early detection efforts it is critical to understand these complex relationships.
