Abstract
Background and Objectives Subjective cognitive decline (SCD) may be indicative of future objective cognitive decline. However, factors other than objective cognitive performance may influence SCD. This review addresses whether family history or close, nonfamilial exposure to dementia is associated with self-reported SCD. Research Design and Methods Searches were conducted in PubMed, PsycINFO, Web of Science, and the Dissertations and Theses database. Eligible articles included measures of self-reported cognition for community-dwelling middle-aged or older adults (40+ years) not diagnosed with dementia, and who had either a family history of dementia, a family member, spouse, or close friend with dementia. The quality of evidence was evaluated using the LEGEND Appraisal Tool. Evidence was synthesized narratively. Results A total of 32 articles were included, with 28 rated as good quality. Across studies, the relationship between dementia exposure and SCD was inconsistent. A significant association between exposure and SCD was found in 6 studies; however, 17 reviewed studies found no evidence of a relationship. The remaining 9 studies found mixed associations. Modifying factors that could potentially influence these associations were exploratorily identified among studies to provide context to our results. These factors included dementia worry, emotional closeness, and measurement sensitivity. Discussion and Implications Findings of this review suggest that both first-degree relatives and spouses of persons with dementia may have an increased likelihood of reporting SCD, although the current heterogeneity in definitions of exposure to dementia and SCD may influence these findings. In addition to the relationship between dementia exposure and SCD, future research should examine potential modifiers, including meaning attributed to exposure, as identifying how these perceptions affect cognition may promote early intervention.

Relationship between consistent subjective cognitive decline and occurrence of falls six months later. Arch Gerontol Geriatr 2023; 104:104841. [PMID: 36265390 DOI: 10.1016/j.archger.2022.104841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 10/10/2022] [Accepted: 10/14/2022] [Indexed: 11/13/2022]
Abstract
PURPOSE To examine the association between consistent subjective cognitive decline and fall occurrence six months later. METHOD A cohort study was conducted at two time points in community-dwelling older adults. The first survey was conducted from May to July 2020 and the second from November 2020 to January 2021. Older adults without missing data who had not fallen during the past year were analyzed. The questionnaire included sociodemographic data, a questionnaire for medical checkup of older adults, and a frailty screening index. We divided the participants into three groups according to the occurrence of subjective cognitive decline (SCD): 1) no SCD (did not complain of SCD at both time points), 2) unstable SCD (complained of SCD once), and 3) consecutive SCD (consistently complained of SCD). Multiple logistic regression analysis was used to examine the association between fall occurrence and SCD. Fall occurrences were obtained from the second survey. RESULTS In total, 322 participants were included in the analysis. The numbers of patients with no SCD, unstable SCD, and consecutive SCD were 226 (70.2%), 61 (19.0%), and 35 (10.9%), respectively. In the second survey, the number of falls was 26 (8.1%). Multiple logistic regression analysis showed that consecutive SCD was associated with fall occurrence, even after adjusting for age, sex, comorbidity, cohabitants, and frailty status (OR:3.143, 95% CI:1.076-9.388); however, unstable SCD was not (OR:2.348, 95% CI:0.816-6.468). CONCLUSION Consistent complaints of SCD were associated with the occurrence of falls. We highlighted the importance of evaluating SCD over time when considering falls.

Abstract
OBJECTIVES Examine race and personal exposure to Alzheimer's Disease (AD) on projected memory failure attributions and medical help-seeking thresholds of pre-morbid adults. The goal is to better understand race discrepancies in help-seeking for those potentially at risk for early-onset AD. METHODS 498 adults aged 40 to 65 (M = 52.27), screened for current memory failure, completed an online questionnaire exploring their help-seeking intentions and threshold, attributions of hypothetical memory failures, and level of AD concern. RESULTS Non-Hispanic Whites (n = 248) were significantly more concerned about AD than African Americans (n = 250) (p =.027). Personal exposure to AD moderated the impact of race on memory failure attributions (p =.036), so that personal exposure was more influential for African Americans. Those who were more likely to attribute hypothetical memory failures to AD had lower projected thresholds for seeking a medical evaluation (p =.010). Memory failure attribution emerged as a potential mediator of the impact of race on projected help-seeking behaviors (p =.057). CONCLUSIONS African Americans were more influenced by personal experience when considering the causes of hypothetical memory failures. CLINICAL IMPLICATIONS Healthcare providers should emphasize to African American families the value of early AD detection and treatment in terms of quality of life for both patient and caregiver.

Abstract
OBJECTIVES To examine relationships between subjective memory impairment (SMI) and parental dementia among in older adults while considering the interactive influence of depressive symptoms, ethnicity, and race. METHOD The sample was drawn from the Health and Retirement Study, a nationally representative longitudinal study of aging (n = 3,809; Mage = 66.09; SD = 1.88; 84.20% White; 12.23% Black; 7.88% Hispanic). Biennial assessments included two measures of SMI (current memory problems and perceived memory decline), depressive symptoms, and parental dementia, over periods of up to sixteen years. Multilevel modeling analyses examined longitudinal relationships between parental dementia and SMI and whether depressive symptoms, ethnicity, and race interactively influenced this association. RESULTS Results showed that when older adults reported parental dementia, they were more likely to report a decline in memory in the past two years. They also reported poorer current memory problems, especially when they experienced increased depressive symptoms. Associations of parental dementia were consistent across ethnicity and race. CONCLUSIONS Results demonstrate the importance of considering parental dementia as a factor that may contribute to SMI in older adults.

Abstract
Objective: Since women tend to use pornography less, they may enroll less in studies concerning it and/or those who do may be gender-atypical. Methods: One study plus replication, assessed proportion of participants reporting being women, responding to each of two, minimally different (one including the word "pornographic") study advertisement versions, and their pornography use frequency, Erotophilia-Erotophobia, and Openness to Experience. Results: Proportion responding to each version did not differ. In one sample only, women responding to one version differed in Openness to Experience. Conclusions: Advertising to North American convenience samples using the word "pornographic", may produce neither self-selection out by, nor over-sampling of gender-atypical, women.

JMIR Res Protoc 2021; 10:e25233. [PMID: 33988514 PMCID: PMC8164128 DOI: 10.2196/25233] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 03/29/2021] [Accepted: 04/13/2021] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Increasing evidence has promoted the clinical utility of self-reported memory problems for detecting early impairment associated with Alzheimer disease (AD). However, previous studies investigating memory problems often conflated the types of problems (ie, retrospective and prospective) with their features (ie, frequency and consequences). This bias limits the specificity of traditional measures of memory problems and minimizes their ability to detect differential trajectories associated with cognitive decline. In this study, we use a novel measure of self-reported memory problems that uses daily reports of memory lapses to disentangle types from features for analyzing the impact of each dimension in two longitudinal data sets. Furthermore, this study explores the individual difference factors of age and gender as potential moderators of the relationships between self-reported memory lapses and objective cognitive decline. OBJECTIVE The aim of this study is to describe the protocol for a secondary data analysis project that explores the relationship between experiences of daily memory lapses and their associations with cognitive decline in middle-aged and older adults. METHODS This study uses multilevel, coordinated analyses across two measurement burst data sets to examine the links between features and consequences of memory lapses (retrospective and prospective) and their association with objective cognitive decline. This study's sample (N=392; aged 50-85 years; n=254, 64.8% women) is drawn from two ongoing, nationally funded research studies: The Effects of Stress on Cognitive Aging, Physiology, and Emotion study and the Einstein Aging Study. Both studies assess the daily experience of memory lapses, including the type as well as the emotional and functional outcomes, and objective measures of cognition, such as processing speed and episodic memory. We will use multilevel modeling to test our conceptual model demonstrating that differences in frequency and types of memory lapses show differential trends in their relationships with cognitive decline and that these relationships vary by the age and gender of participants. RESULTS This project was funded in August 2019. The approval for secondary data analysis was given by the institutional review board in February 2020. Data analysis for this project has not yet started. CONCLUSIONS The early and accurate identification of individuals most at risk for cognitive decline is of paramount importance. Previous research exploring self-reported memory problems and AD is promising; however, limitations in measurement may explain previous reports of inconsistences. This study addresses these concerns by examining daily reports of memory lapses, how these vary by age and gender, and their relationship with objective cognitive performance. Overall, this study aims to identify the key features of daily memory lapses and the differential trajectories that best predict cognitive decline to help inform future AD risk screening tools.

Abstract
Aim The aim of this study was to investigate potential barriers to help-seeking for memory problems as well as outreach to providers. Findings Participants who endorsed having hearing problems were the most likely to endorse barriers to help-seeking as well as speaking to a physician. Message Physicians and healthcare agencies can work to design outreach for persons who experience barriers, particularly hearing loss. Purpose Early detection of age- and disease-related cognitive problems affords patients the opportunities to receive medical treatment, engage in research, and plan for the future. Understanding help-seeking behavior has potential to aid both patients and clinicians. This study was designed to identify predictors of endorsed barriers to memory-related help-seeking as well as medical help-seeking endorsement. Methods This cross-sectional correlational study used a convenience sample of 97 older adults. The participants answered anonymous questionnaires about subjective memory, mood, and health and several items designed to investigate help-seeking for memory issues. Results Persons who endorsed multiple barriers to help-seeking were more likely to also endorse having hearing problems. In addition, participants who reported that they would not talk to a doctor or physician about memory concerns also had significantly worse subjective hearing. Conclusion Hearing loss may be a particular risk for not seeking help for memory problems. Physicians and healthcare agencies can work to design outreach for persons who experience barriers, such as hearing loss and the concomitant outcomes.

Abstract
Objectives: To determine if the fear of developing Alzheimer's disease (FDAD) construct, in combination with similar psychoemotional factors, could help elucidate the nature of older adults' subjective memory complaints (SMCs) and subsequent objective memory performance.Methods: One hundred ninety-three healthy older adults (aged 65-93) were administered clinician and self-report measures of depression, worry, anxiety, illness attitudes, and memory, and each rated their concern with developing AD.Results: Self-reported FDAD was not associated with objective memory performance (p > .05). FDAD, trait anxiety, general anxiety, and general and illness-related worry were independently associated with subjective memory report (ps < .05). The relationship between FDAD and subjective memory report was mediated by measures of general trait and state anxiety, but not general worry or illness-specific worry.Conclusions: FDAD was not associated with objective memory functioning, suggesting AD concerns were not reflective of memory pathology. The mediating effect of anxiety on the relationship between FDAD and subjective memory report suggests that assessment of anxiety, beyond AD fear, may help identify older adults at risk for developing negative perceptions of memory and related distress.

Abstract
This study explored psychosocial and cognitive predictors of perceived threat of Alzheimer's disease (AD). Respondents were 1641 adults (mean age: 64.4; 54% female; 82% white) who completed a module in the Health and Retirement Study, a nationally representative survey of adults aged ≥50. Findings show that perceived threat was significantly higher for those aged 50 to 64 ( P < .001) and 65 to 74 ( P < .05) than for those ≥75. Respondents with a family history of AD had significantly greater perceived threat ( P < .001) than those with no experience. Stronger endorsement of the beliefs that stress ( P < .01) or genetics ( P < .01) are important AD risk factors was significantly associated with greater perceived threat, as was having more depressive symptoms ( P < .01), poorer self-rated memory ( P < .01), and lower cognitive function ( P < .01). Personal experience moderated the relationship between perceived threat and 2 variables: age and self-rated memory. Understanding perceived AD threat may inform practice and policies centered on early and accurate diagnosis.

Abstract
This study examined the patterns and predictors of help-seeking behavior for personal concerns about developing Alzheimer’s disease (AD) among middle-aged persons. Data were obtained from a survey of two subsamples of 40- to 60-year-old adults with concerns about AD: (a) 99 adult children with a living parent with a diagnosis of probable AD and(b)70 adults in a matched group with no parental history of AD. Descriptive analyses of the types and levels of help seeking show that respondents who are concerned about developing AD take their fears mainly to their informal rather than formal networks. Bivariate and multivariate analyses identified significant correlates of help seeking within three clusters: memory assessment, AD experience, and sociodemographics. The most robust predictors were aspects of AD experience. Understanding the patterns and correlates of help seeking for AD concerns can help health care professionals to develop more effective models of early intervention with implications for early detection of the disease.

Abstract
With increased societal awareness of dementia, older adults show increased concern about developing dementia, leading to misidentification of aging-related cognitive glitches as signs of dementia. While some researchers have suggested self-reported cognitive concerns accurately identify older adults with early signs of dementia, there is evidence that subjective cognitive decline is not associated with objective cognitive performance and instead reflects psychological factors consistent with models of health anxiety, including dementia worry. We examined the construct of dementia worry and its relationship to subjective memory concerns in 100 older adults (Mage = 69 years) without signs of dementia, using a recently developed measure of dementia worry. Consistent with hypotheses, dementia worry was related to exposure to dementia, having a high number of depressive or general worry symptoms, and having more memory concerns. Exposure to dementia moderated the relationship of dementia worry to depression and general worry. Furthermore, dementia worry moderated the relationship of objective memory impairment to subjective memory ratings. The results provide further evidence of the role of psychological factors such as dementia worry in subjective memory report and emphasize the need for objective cognitive testing before making determinations about dementia in older adults expressing memory concerns.

Abstract
Anticipatory dementia is related to anxiety, which is a clinical predictor of early conversion to Alzheimer's disease. The Fear of Alzheimer's Disease Scale (FADS) is a reliable and valid instrument to address anticipatory dementia. The aim of the present investigation was to develop the Korean version of the Fear of Alzheimer's Disease Scale (K-FADS) and to verify its reliability and validity. We developed the K-FADS to consist of 30 items with total scores ranging from 0 to 120, as in the original FADS. One hundred eight healthy volunteer participants, drawn from 3 different university hospitals, were evaluated. The K-FADS revealed good reliability (Cronbach α=0.96) and good validity as compared to the Korean version of the State-Trait Anxiety Inventory Form (r=0.242, P=0.013). Test-retest reliability was excellent, as the intra-class correlation coefficient comparing the retest to test was 0.98 (95% confidence interval, 0.96-0.99). Our results show that the K-FADS is a suitable and valuable scale to assess anticipatory dementia in elderly Koreans.

Abstract
Screening rates for Alzheimer’s disease (AD) and memory impairment are low. There is misinformation, fear, and stigma associated with memory loss and aging. Physicians are slow or reluctant to screen for memory impairment in older adults. The challenges to effective screening for AD are not unique. Thirty years ago, screening for breast cancer also suffered from low participation, fear, stigma, and misinformation. Targeted public health strategies increased disease awareness and early detection for breast cancer, and today, breast cancer screening is generally accepted by health care providers and the public. Strategies used to increase breast cancer screening can serve as examples for the promotion of screening and early detection for AD.

Abstract
BACKGROUND As the prevalence of Alzheimer's disease (AD) is rapidly increasing, apprehension about developing the degenerative disease (anticipatory dementia or fear of developing AD) has become a topic of interest. However, most studies of anticipatory dementia have utilized brief, nonvalidated measures to explore older adults' apprehension. As such, there is a significant need for a psychometrically sound instrument to measure this fear. METHODS The current study utilized 101 older adults ages 65 to 91 to develop and validate an important new scale, the Fear of Alzheimer's Disease Scale (FADS). Construct validity of the FADS was assessed with the State-Trait Anxiety Inventory-Form Y (STAI-Y). RESULTS Analyses revealed a three-factor model for the FADS (i.e., General Fear, Physical Symptoms, and Catastrophic Attitude) and an α of 0.94 for the entire measure, indicating good internal consistency. The FADS demonstrated good construct validity, as it was significantly correlated with both the state and trait subscales of the STAI-Y, with the trait subscale yielding the highest correlation. CONCLUSION The FADS is a reliable and valid instrument and is the first of its kind available to directly address anticipatory dementia among a general population of older adults.

Abstract
In this monograph, we ask whether various kinds of intellectual, physical, and social activities produce cognitive enrichment effects-that is, whether they improve cognitive performance at different points of the adult life span, with a particular emphasis on old age. We begin with a theoretical framework that emphasizes the potential of behavior to influence levels of cognitive functioning. According to this framework, the undeniable presence of age-related decline in cognition does not invalidate the view that behavior can enhance cognitive functioning. Instead, the course of normal aging shapes a zone of possible functioning, which reflects person-specific endowments and age-related constraints. Individuals influence whether they function in the higher or lower ranges of this zone by engaging in or refraining from beneficial intellectual, physical, and social activities. From this point of view, the potential for positive change, or plasticity, is maintained in adult cognition. It is an argument that is supported by newer research in neuroscience showing neural plasticity in various aspects of central nervous system functioning, neurochemistry, and architecture. This view of human potential contrasts with static conceptions of cognition in old age, according to which decline in abilities is fixed and individuals cannot slow its course. Furthermore, any understanding of cognition as it occurs in everyday life must make a distinction between basic cognitive mechanisms and skills (such as working-memory capacity) and the functional use of cognition to achieve goals in specific situations. In practice, knowledge and expertise are critical for effective functioning, and the available evidence suggests that older adults effectively employ specific knowledge and expertise and can gain new knowledge when it is required. We conclude that, on balance, the available evidence favors the hypothesis that maintaining an intellectually engaged and physically active lifestyle promotes successful cognitive aging. First, cognitive-training studies have demonstrated that older adults can improve cognitive functioning when provided with intensive training in strategies that promote thinking and remembering. The early training literature suggested little transfer of function from specifically trained skills to new cognitive tasks; learning was highly specific to the cognitive processes targeted by training. Recently, however, a new generation of studies suggests that providing structured experience in situations demanding executive coordination of skills-such as complex video games, task-switching paradigms, and divided attention tasks-train strategic control over cognition that does show transfer to different task environments. These studies suggest that there is considerable reserve potential in older adults' cognition that can be enhanced through training. Second, a considerable number of studies indicate that maintaining a lifestyle that is intellectually stimulating predicts better maintenance of cognitive skills and is associated with a reduced risk of developing Alzheimer's disease in late life. Our review focuses on longitudinal evidence of a connection between an active lifestyle and enhanced cognition, because such evidence admits fewer rival explanations of observed effects (or lack of effects) than does cross-sectional evidence. The longitudinal evidence consistently shows that engaging in intellectually stimulating activities is associated with better cognitive functioning at later points in time. Other studies show that meaningful social engagement is also predictive of better maintenance of cognitive functioning in old age. These longitudinal findings are also open to important rival explanations, but overall, the available evidence suggests that activities can postpone decline, attenuate decline, or provide prosthetic benefit in the face of normative cognitive decline, while at the same time indicating that late-life cognitive changes can result in curtailment of activities. Given the complexity of the dynamic reciprocal relationships between stimulating activities and cognitive function in old age, additional research will be needed to address the extent to which observed effects validate a causal influence of an intellectually engaged lifestyle on cognition. Nevertheless, the hypothesis that an active lifestyle that requires cognitive effort has long-term benefits for older adults' cognition is at least consistent with the available data. Furthermore, new intervention research that involves multimodal interventions focusing on goal-directed action requiring cognition (such as reading to children) and social interaction will help to address whether an active lifestyle enhances cognitive function. Third, there is a parallel literature suggesting that physical activity, and aerobic exercise in particular, enhances older adults' cognitive function. Unlike the literature on an active lifestyle, there is already an impressive array of work with humans and animal populations showing that exercise interventions have substantial benefits for cognitive function, particularly for aspects of fluid intelligence and executive function. Recent neuroscience research on this topic indicates that exercise has substantial effects on brain morphology and function, representing a plausible brain substrate for the observed effects of aerobic exercise and other activities on cognition. Our review identifies a number of areas where additional research is needed to address critical questions. For example, there is considerable epidemiological evidence that stress and chronic psychological distress are negatively associated with changes in cognition. In contrast, less is known about how positive attributes, such as self-efficacy, a sense of control, and a sense of meaning in life, might contribute to preservation of cognitive function in old age. It is well known that certain personality characteristics such as conscientiousness predict adherence to an exercise regimen, but we do not know whether these attributes are also relevant to predicting maintenance of cognitive function or effective compensation for cognitive decline when it occurs. Likewise, more information is needed on the factors that encourage maintenance of an active lifestyle in old age in the face of elevated risk for physiological decline, mechanical wear and tear on the body, and incidence of diseases with disabling consequences, and whether efforts to maintain an active lifestyle are associated with successful aging, both in terms of cognitive function and psychological and emotional well-being. We also discuss briefly some interesting issues for society and public policy regarding cognitive-enrichment effects. For example, should efforts to enhance cognitive function be included as part of a general prevention model for enhancing health and vitality in old age? We also comment on the recent trend of business marketing interventions claimed to build brain power and prevent age-related cognitive decline, and the desirability of direct research evidence to back claims of effectiveness for specific products.

Abstract
The fear of developing Alzheimer disease (AD) is highly salient, particularly for biologic family members. The current study evaluated social/cognitive explanations for perceived AD threat beyond genetic relatedness, including personal experience with AD, belief in negative aging stereotypes, and performance on delayed memory tasks. Participants were 97 healthy older adults aged 50 to 85, self-referred for a free community memory screen. Results showed that, as expected, personal AD experience was related to perceived AD threat. Furthermore, consistent with expectations, AD experience moderated the relationship between perceived AD threat and other explanatory variables, including age, belief in negative aging stereotypes, and cognitive performance. In those with AD experience, whether genetic or not, younger age was associated with more perceived AD threat, but an inverse relationship was seen in those without AD experience. Those with genetic AD experience seem particularly vulnerable to the effects of negative age stereotype beliefs on perceived AD threat, and show an inverse relationship between their actual cognitive performance and their perception of personal AD threat. Results highlight the importance of considering personal experience with AD when assessing a person's self-reported concerns about AD or his/her own memory changes.
