Short-Term Lifestyle Strategies for Sustaining Cognitive Status

Cognitive decline impacts older adults, particularly their independence. The goal of this project was to increase understanding of how short-term, everyday lifestyle options, including physical activity, help an older adult sustain cognitive independence. Using a secondary analysis of lifestyle choices, we drew on a dataset of 4,620 community-dwelling elders in the US, assessed at baseline and one year later using 2 valid and reliable tools, the interRAI Community Health Assessment and the interRAI Wellness tool. Decline or no decline on the Cognitive Performance Scale was the dependent variable. We examined sustaining one's status on this measure over a one-year period in relation to key dimensions of wellness through intellectual, physical, emotional, social, and spiritual variables. Engaging in physical activity, formal exercise, and specific recreational activities had a favorable effect on short-term cognitive decline. Involvement with computers, crossword puzzles, handicrafts, and formal education courses also were protective factors. The physical and intellectual domains of wellness are prominent aspects in protection from cognitive decline. Inherent in these two domains are mutable factors suitable for targeted efforts to promote older adult health and well-being.

The psychological impact of dependency in adults with chronic fatigue syndrome/myalgic encephalomyelitis: A qualitative exploration

Chronic fatigue syndrome/myalgic encephalomyelitis can limit functional capacity, producing various degrees of disability and psychological distress. Semi-structured interviews explored the experiences of adults with chronic fatigue syndrome/myalgic encephalomyelitis being physically dependent on other people for help in daily life, and whether physical dependency affects their psychological well-being. Thematic analysis generated six themes: loss of independence and self-identity, an invisible illness, anxieties of today and the future, catch-22, internalised anger, and acceptance of the condition. The findings provide insight into the psychological impact of dependency. Implications for intervention include better education relating to chronic fatigue syndrome/myalgic encephalomyelitis for family members, carers, and friends; ways to communicate their needs to others who may not understand chronic fatigue syndrome/myalgic encephalomyelitis; and awareness that acceptance of the condition could improve psychological well-being.

Five dimensions of wellness and predictors of cognitive health protection in community-dwelling older adults: a historical COLLAGE cohort study

Wellness is associated with cognitive health protection; however, findings are limited because they only examine variable(s) within one dimension of wellness. This research examined the association between multiple dimensions of wellness and cognition among aging adults. The sample included 5,605 male and female community-dwelling adults 60 years and older. Four dimensions of wellness demonstrated a statistically significant higher mean difference in cognitively healthy older adults compared to cognitively impaired older adults, F(4, 5,595) = 47.57, p < .001. Emotional wellness demonstrated the strongest association with cognitive health, followed by physical and spiritual wellness, F(5, 5,372) = 50.35, p < .001. Future research is needed to examine the cognitive protective benefits of wellness using longitudinal, prospective designs that control for the potential temporal relationship between wellness and cognition.

The Six Dimensions of Wellness and Cognition in Aging Adults

Objective: Examine how wellness in six dimensions (occupational, social, intellectual, physical, emotional, and spiritual) protects cognition in aging adults. Background: cognitive impairment increases with age. Baby boomers represent a significant percent of the population at risk for cognitive impairment. Cognitive impairment has a negative impact on nursing resources, health care finances, patient mortality, and quality of life. Wellness and prevention is one focus of Institute of Medicine’s vision for the future of nursing. Method: Literature was retrieved from Cumulative Index to Nursing and Allied Health Literature and MEDLINE. Research that examined the affect of wellness in each of the six dimensions on cognition in older adults was included. Results: One or more of the following may protect cognition in aging: midlife occupation complexity, marriage, social networks, formal education, intellectual activities, physical activity, healthy nutrition, motivational ability, purpose in life, and spirituality. Conclusion: Wellness in one or more of the six dimensions may protect cognition in aging. The cognitive protective benefits may increase when wellness in more than one dimension is demonstrated. High wellness in one dimension may protect cognition by compensating for low wellness in another dimension. The interconnectedness of each of the dimensions signifies the importance of evaluating older adults holistically. Wellness throughout the life span may result in improved cognition in aging. Application: Future research is needed to examine the relationship between the six dimensions of wellness and cognition, and to determine if one dimension of wellness is a significant predictor of cognitive health in aging adults.

'Keeping your brain active': the activities of people aged 50-65 years

OBJECTIVE

The paper aims to construct a baseline of knowledge about current activities, attitudes and motivations of a sample of people aged 50-65 years in relation to 'keeping one's brain active', with a particular focus on activities suggested in the literature and in popular parlance to have positive effects.

METHODS

An online survey of people aged 50-65 years concerning their activities and motivations in relation to 'keeping one's brain active' was conducted with a sample of people employed in Scotland and in two online discussion forums. The survey ascertained respondents' background demographic data, data on health and lifestyle factors, activities they engaged in and reasons for engagement, including any concerns about dementia and experience of dementia. The achieved sample of 402 responses was representative of the general population on most counts, although the sample included more better-educated people and more smokers.

RESULTS

Dementia prevention was a motivating factor for 21% of the respondents. More women and more of those living alone reported this motivation. It was linked with experience of dementia and future fears of developing the condition. New 'brain-training' technologies were used by younger people in higher socio-economic groups, and dementia prevention was cited as a motivation.

CONCLUSION

The findings indicate that dementia prevention motivates activities perceived to keep the brain active, despite there being a virtual absence of scientific evidence showing that the desired effects will follow. Given the existence of evidence suggesting that other activities, particularly physical exercise, may be more important and the possibility that stress itself may promote the development of dementia, further research is urgently needed.

Ethnically Diverse Older Adults' Beliefs about Staying Mentally Sharp

This study examined diverse older adults' ( n = 396, ages 50+) views about how to stay mentally sharp. We conducted 42 focus groups in four languages at nine United States locations using a standardized discussion guide and methods. The groups represented African Americans, American Indians, Chinese Americans, Latinos, Whites other than Latinos, and Vietnamese Americans. All groups mentioned benefits of social interaction. All groups, especially Chinese and African Americans, mentioned benefits of community engagement. Participants in all groups expressed their belief that mental stimulation, particularly reading, promoted cognitive health; African Americans and Whites were especially likely to say that mental exercises (e.g., puzzles) were useful. Results suggest opportunities for education about potential cognitive health benefits of being socially connected through senior center activities and volunteer programs.

Cross-validation of the Florida Cognitive Activities Scale (FCAS) in an Alzheimer's disease research center sample

We conducted a cross-validation study of the Florida Cognitive Activities Scale (FCAS) in a sample of heterogeneously diagnosed elderly participants in the Florida Alzheimer's Disease Research Center. FCAS scales were found to be significantly correlated with neuropsychological measures and with ratings of medial temporal atrophy (MTA). The pattern of significant differences in FCAS scores among groups of normals, those with mild cognitive impairment, and early-stage Alzheimer disease cases suggests that the cognitive activities tapped by the FCAS are affected throughout disease progression in the same way as the neuropsychological performance measures. Notably, FCAS score differences among these groups were as large as they were for ratings of MTA. The accumulation of reliability and validity data indicates that the FCAS scales are sensitive measures of individual differences in cognitive activity and would serve as valid longitudinal measures of change in the study of aging, cognitive decline, and degenerative dementia.
