Examining the influence of self-care practices on brain activity in healthy older adults.

Introduction: Studies on the aging brain often occur in active settings, but comparatively few investigate brain activity in resting states. However, exploring brain activity in a resting state offers valuable insights into spontaneous neural processes unaffected by task-specific influences. Objective: To investigate the relationship between self-care practices, cognitive function, and patterns of brain activity in healthy older adults, taking into account predictions from aging brain models. Methodology: 77 older adults aged 61 to 87 completing a self-care practices questionnaire, neuropsychological tests, and resting-state electroencephalogram (EEG) recordings. Participants were classified into two groups according to their self-care practices: traditional self-care (T-SC) and developmental self-care (D-SC). Results: Although neuropsychological tests did not yield significant differences between the D-SC and T-SC groups, patterns of brain activity revealed distinct behaviors. The T-SC group demonstrated patterns more consistent with established aging brain models, contrasting with the D-SC group, which exhibited brain activity akin to that observed in younger adults. Specifically, the T-SC group displayed hyperactivation related to memory and executive function performance, alongside heightened alpha power in posterior regions. Furthermore, bilateral frontal activation in the beta band was evident. Conclusions: The findings suggest a nuanced relationship between self-care practices and brain activity in older adults. While the T-SC group demonstrated brain activity patterns consistent with conservative aging, indicating the preservation of typical aging characteristics, the D-SC group displayed activity suggestive of a potential protective effect. This effect may be linked to self-care strategies that foster development and resilience in cognitive aging.

Self-care interventions of community-dwelling older adults: a systematic review and meta-analysis.

Introduction: The current notion of "care in old age" should be reconceptualized in the ageing societies of the 21st century. Currently, "being old" means that one is actively involved in their care and has the desire to retain control and independence. Objective: Understand and analyze the efficacy of interventions in the physical and psychological self-care practices of healthy community-dwelling older people. Methodology: Systematic review and meta-analysis. The guidelines of the PRISMA guide were followed. The methodological quality of the studies was checked using Cochrane Effective Practice and Organisation of Care criteria, and the search was performed between 2016 and 2021. Results: Of the 1,866 evaluated, 8 studies met the criteria. The systematic review reveals that self-care interventions focus on physical health-related variables but not on psychological variables. The meta-analysis shows that interventions significantly improve physical health-related variables (care visits, hospital admission, medication, and gait speed). Conclusion: Self-care training programs should include psychological variables to increase health and well-being in healthy older people.

Practices of Self-Care in Healthy Old Age: A Field Study.

Two competing psychological approaches for how to care for oneself to stay healthy in old age have coexisted and dominated the scientific literature. OBJECTIVE: Identify the self-care practices of healthy older adults and establish the relationship between these practices and the cognitive processes involved. METHOD: 105 healthy older people (83.91% women) recorded their self-care practices using the Care Time Test and underwent a cognitive evaluation. RESULTS: The frequency and variety of different activities that participants spent performing on a day of the week where they had the fewest obligations are as follows: nearly 7 h on seven survival activities, 4 h and 30 min on three maintenance of functional independence activities and 1 h on one activity that promoted personal development. Older people who carry out activities in a developmental approach showed better everyday memory (8.63 points) and attention levels (7.00 points) than older people who carry out activities using a conservative approach (memory: 7.43; attention level: 6.40). CONCLUSION: The results evidenced that the frequency and variety of activities that promote personal development are associated with better attention and memory performance.
