Objectives Psychological well-being (PWB) may be a potential modifiable risk factor of age-related diseases. We aimed to determine associations of PWB with sensorineural and cognitive function and neuronal health in middle-aged adults. Methods This study included 2039 Beaver Dam Offspring Study participants. We assessed PWB, hearing, visual acuity, contrast sensitivity impairment, olfactory impairment, cognition, and retinal (macular ganglion cell inner-plexiform layer, mGCIPL) thickness. Age-sex-education-adjusted multivariable linear, logistic regression, and generalized estimating equation models were used and then further adjusted for health-related confounders. Results Individuals with higher PWB had better hearing functions, visual acuity, and thicker mGCIPL and reduced odds for hearing, contrast sensitivity and olfactory impairment in age-sex-education-adjusted models. Effects on mGCIPL and visual and olfactory measures decreased with adjustment. Higher PWB was associated with better cognition, better combined sensorineural-cognitive function, and decreased cognitive impairment. Discussion Psychological well-being was associated with sensorineural-cognitive health indicating a potential of PWB interventions for healthy aging.

Population aging is one of the most important social trends of the 21st century and in the United States, the number of people aged ≥65 is projected to increase by nearly 50% in the next 15 years. Most biomedical and public health efforts have focused on reducing harmful risk factors when targeting chronic disease—an approach that has contributed greatly to prevention and treatment programs. However, evidence suggests that the number of years lost to disability is increasing and historic gains we have made in life expectancy are eroding, and even reversing in some groups. As our society ages and grapples with these issues, expanding the focus to include resilience, as well as psychosocial assets in our prevention and treatment programs might help inform the multidisciplinary response effort we need. Here we synthesize research evaluating associations between different dimensions of psychological well-being (e.g., purpose in life, optimism, life satisfaction) and social well-being (e.g., structural, functional, quality) with chronic conditions. We also evaluate evidence around three biopsychosocial pathways hypothesized to underlie these associations. These factors are meaningful, measurable, and potentially modifiable; thus, further pursuing this line of inquiry might unveil innovative paths to enhancing the health of our rapidly aging society.

The brain’s default network (DN) has received considerable interest in the context of so-called “normal” and pathological aging. Findings have generally been couched in support of a pessimistic view of brain aging, marked by substantial loss of structural brain integrity accompanied by a host of impairments in brain and cognitive function. A critical look at the literature, however, reveals that the standard loss of integrity, loss of function (LILF) view in normal aging may not necessarily hold with respect to the DN and the internally guided functions it supports. Many internally guided processes subserved by the DN are preserved or enhanced in cognitively healthy older adults. Moreover, differences in motivational, contextual, and physiological factors between young and older adults likely influence the extant neuroimaging and cognitive findings. Accordingly, normal aging can be viewed as a series of possibly adaptive cognitive and DN-related alterations that bolster cognitive function and promote socioemotional well-being and stability in a stage of life noted for change. On the other hand, the available evidence reveals strong support for the LILF view of the DN in neurodegenerative disorders, whereby syndromes such as Alzheimer’s disease (AD) and semantic dementia (SD), characterized by progressive atrophy to distinct DN subsystems, display distinct aberrations in autobiographical and semantic cognition. Taken together, these findings call for more naturalistic, age-appropriate, and longitudinal paradigms when investigating neurocognitive changes in aging and to adequately assess and control for differences in non-neural factors that may obscure “true” effects of normal and pathological aging. A shift in the framework with which age-related alterations in internally guided cognition are interpreted may shed important light on the neurocognitive mechanisms differentiating healthy and pathological aging, leading to a more complete picture of the aging brain in all its complexity.

Effects Of Aging

The questions of whether and why language processes change in healthy aging require complicated answers. Although comprehension appears to be more stable across adulthood than does production, there is evidence for age-related changes and also for constancy within both input and output components of language. Further, these changes can be considered at various levels of the language hierarchy, such as sensory input, words, sentences, and discourse. As concluded in several other comprehensive reviews, older adults’ language production ability declines much more noticeably than does their comprehension, presumably because comprehension is able to benefit from contextual processing in a way that production cannot. Specifically, lexical and orthographic retrieval become more difficult during normal aging, and these changes appear to represent the most noticeable age-related declines in language production. Some theories of age-related decline focus on global deterioration of cognitive function, whereas other theories predict changes in specific processes related to language function. Both types of theories have received empirical support as applied to language performance, although additional theoretical development is still needed to capture the patterns of effects. Further, in order to truly understand how cognitive aging impacts the ability to understand and produce language, it is necessary to examine how age-related shifts in goals, expertise, and compensatory strategies influence language processes. There are important implications of research on language and cognitive aging, in that language can play a role in physical health and psychological well-being. In summary, our review of the existing literature on language and cognitive aging supports previous claims that language ability is asymmetrically impacted by age, with smaller overall effects of aging on comprehension than production processes.

The Life Course

The context in which dependents, regardless of age, receive care affects their health. This study adapted the Home Observation for Measurement of the Environment (HOME) Inventory, originally designed for child development research, to assess the quality of stimulation and support available to elders in their habitual households in Sri Lanka. Whether the adapted domains correlated with indicators of health and well-being in ways consistent with the child development literature was then examined. Through mixed-methods research based on 248 household surveys, four focus groups, and 15 interviews, three domains emerged: Physical Environment, Variety of Stimulation, and Emotional and Verbal Responsiveness. Regression modeling revealed that a higher quality physical home environment correlated with two measures of cognitive function after adjusting for covariates, but no consistent association with two psychological well-being scales. In contrast, higher Variety of Stimulation scores correlated with better cognitive function and lower psychological distress. There was no consistent correlation between Responsiveness and selected health outcomes. Qualitative data indicate that elders are active household contributors who strive to achieve harmonious relations with coresident kin. These findings reveal notable synergies between early and late life efforts to improve cognitive and psychological health, and highlight household considerations for future healthy aging research.

Abstract Motion perception is affected by healthy aging, which impairs the ability of older adults to perform some daily activities such as driving. The current study investigated the underlying causes of age-related motion contrast sensitivity losses by using an equivalent noise paradigm to decompose motion contrast sensitivity into calculation efficiency, the temporal modulation transfer function (i.e., temporal blur) and 3 sources of internal noise: stochastic absorption of photons by photoreceptors (i.e., photon noise), neural noise occurring at the retinal level (i.e., early noise) and at the cortical level (i.e., late noise). These sources of internal noise can be disentangled because there impacts on motion contrast sensitivity vary differently as a function of luminance intensity. The impact of healthy aging on these factors was evaluated by measuring motion contrast sensitivity of young and older healthy adults at different luminance intensities, temporal frequencies and with/without external noise. The older adults were found to have higher photon noise, which suggests a lower photon absorption rate of cones. When roughly equating the amount of photons being absorbed by the photoreceptors, older adults had lower calculation efficiencies, but no significant aging effect was found on temporal modulation transfer function, early noise and late noise.

Objectives: The contribution of vascular disease to neurocognitive decline is now widely recognized. Fetuin-A is an abundant plasma protein known to predict vascular disease. Prior studies have shown that fetuin-A levels are lower in patients with Alzheimer’s disease in direct proportion to the severity of cognitive impairment; however, their association with normal cognitive aging is unknown. We evaluated the association of serum fetuin-A levels with cognitive function in relatively high-functioning, community-dwelling older adults from the Rancho Bernardo Study. Methods: This is a population-based study of 1382 older adults (median age 75) who had plasma fetuin-A levels and cognitive function evaluated in 1992-96; 855 had repeat cognitive function assessment a median of 4 years later. Results: Adjusting for age, sex, education, and depression, higher levels of fetuin-A were associated with better baseline performance on the Mini-Mental Status Exam (MMSE) (P=0.012) and a tendency for better Trails Making B scores (P=0.066). In longitudinal analyses, the likelihood of a major decline (highest decile of change) in Trails B was 29% lower (P=0.010) for each SD higher baseline fetuin-A level; odds of major decline in MMSE was 42% lower (P=0.005) per SD higher fetuin-A for individuals with no known CVD, but were not related to fetuin-A in those with CVD (P=0.33). Fetuin-A was not related to Category Fluency performance. Results did not vary by sex and were not explained by numerous vascular risk factors and comorbidities. Conclusions: Higher plasma fetuin-A concentrations are associated with better performance on tests of global cognitive function and executive function and with reduced likelihood of major decline in these cognitive abilities over a 4-year period. These observations are consistent with the hypothesis that higher fetuin-A protects against cognitive decline in relatively high functioning older adults, although this may be less apparent in those with established vascular disease. Fetuin-A may serve as a biological link between vascular disease and normal age-related cognitive decline.

Psychological Well Being

ABSTRACTBackground: Frailty can be defined as the presence of multiple, interacting medical and functional problems. Frailty is associated with psychiatric conditions but its relation to psychological well-being is unclear. A “frailty identity crisis” has been proposed as a maladaptive response to the sense of self as health deficits accumulate. We evaluated this so-called identity crisis by investigating associations between well-being, frailty, and mortality in community-dwelling older Canadians.Methods: In this secondary analysis of the Canadian Study of Health and Aging (N = 5,703; age 70+), frailty was defined by an index of 33 health deficits. Psychological well-being was measured using Ryff's 18-item scale, with six domains (autonomy, personal growth, environmental mastery, positive relations, purpose in life, and self-acceptance). Cognition was measured using the Modified Mini-Mental State Examination. Associations between well-being, frailty, and mortality were measured using linear regression, adjusting for age, sex, education, cognition, and mental health.Results: For each additional frailty-defining deficit, the psychological well-being score worsened by 0.3 points (0.29, 95% CI: 0.22–0.36, p < 0.001), independent of age, sex, education, cognition, and mental health. Among the six domains of well-being, only “purpose in life” and “autonomy” were not associated with frailty (all others, p < 0.001). Worse psychological well-being was associated with five-year mortality independent of age, sex, education, frailty, and mental health; this association was not statistically significant when adjusting for baseline cognition.Conclusions: Frailty was associated with low levels of well-being. Psychological well-being impaired by a frailty identity crisis may play an important role in defining subjective health in older adults.

Purpose: To investigate the value of visual acuity and patient-perceived visual function test when subretinal drusenoid deposits (SDD) are incorporated into the classification of age-related macular degeneration (AMD). A total of 50 participants were recruited into the study in these groups: healthy ageing (n = 11), intermediate AMD (iAMD) with no SDD (n = 17), iAMD with SDD (n = 11) and non-foveal atrophic AMD (n = 11) confirmed by two retinal imaging modalities. Best-corrected visual acuity (BCVA) and low luminance visual acuity (LLVA) were measured and low luminance deficit (LLD) was calculated. Participants were also interviewed with the low luminance questionnaire (LLQ). Linear regression was used to assess function–function relations. Compared with healthy participants, BCVA and LLVA scores were significantly reduced in the atrophic AMD group (p < 0.0001 and p = 0.00016, respectively) and in patients with SDD (p = 0.028 and p = 0.045, respectively). Participants with atrophy also had reduced BCVA (p = 0.001) and LLVA (p = 0.009) compared with the iAMD no SDD group. However, there were no differences in visual function tests between healthy aging and iAMD without SDD and between iAMD with SDD and atrophic AMD groups. The LLD score did not differ between groups. BCVA and LLVA correlated well. The LLQ did not correlate with visual function tests. This study shows that LLD is not a marker of disease severity as assessed clinically. Although LLQ is a good marker for disease severity using the current AMD classification, it does not differentiate between eyes with and without SDD. Eyes with non-macular geographic atrophy and SDD had lower function than eyes with no SDD and healthy controls.
