AI Article Synopsis
- The study aims to explore the relationship between quality of life (QOL) and cognitive function in elderly individuals living in the community.
- A total of 12,059 seniors were invited to participate, with 1,920 completing both cognitive screenings and QOL questionnaires, which assessed various aspects like daily activities and mental health.
- Results showed that cognitive function significantly influences QOL scores, more so than factors like gender or age, indicating the importance of mental capabilities for overall well-being in older adults.
Article Abstract
Aim: It has become important for elderly to live better rather than to live longer. There have been many reports about quality of life (QOL) of the elderly, but we have no knowledge about the relation between the QOL and the cognitive function. We investigated the relationship between the QOL and the cognitive function among community-dwelling elderly.
Methods: A total of 12,059 community-dwelling elderly were invited to join a cognitive screening study by telephone (TICS-J) combined with a mailed QOL questionnaire. Among them, 1,920 subjects (age 71.87+/-5.50 (mean+/-SD) years old, duration of education 11.08+/-2.61 years) who completed both TICS-J and QOL questionnaire were actually measured. TICS-J was administered by the previously reported method, and the QOL questionnaire was developed based on the component of QOL proposed by Lawton, and consisted of 6 subscales (daily activity, satisfaction with health, satisfaction with human support, satisfaction with economic state, symptoms of depression, and positive mental attitude). Correlations were analyzed among the scores of TICS-J, age, duration of education, and scores on each QOL subscale. Multiple linear regression analysis was conducted after QOL subscale scores, adjusting for gender, age, and duration of education, were entered as dependent variables.
Results: Four out of 6 subscales scores of QOL showed significant differences between men and women. All QOL subscale scores showed significant differences between the two groups in the TICS-J scores. Partial correlations were seen among TICS-J scores and each QOL subscale score. Multiple linear regression analysis revealed significant influence of cognitive function by TICS-J on QOL subscales scores.
Conclusions: Cognitive function was considered to have more influence on QOL scores than gender or age. TICS-J and the QOL questionnaire in this study were useful to evaluate the outcome of welfare in community-dwelling elderly.

Department of Bioengineering, University of California, San Diego, La Jolla, CA, 92093, USA.
Background: PSEN1, PSEN2, and APP mutations cause Alzheimer's disease (AD) with an early age at onset (AAO) and progressive cognitive decline. PSEN1 mutations are more common and generally have an earlier AAO; however, certain PSEN1 mutations cause a later AAO, similar to those observed in PSEN2 and APP.
Methods: We examined whether common disease endotypes exist across these mutations with a later AAO (~ 55 years) using hiPSC-derived neurons from familial Alzheimer's disease (FAD) patients harboring mutations in PSEN1, PSEN2, and APP and mechanistically characterized by integrating RNA-seq and ATAC-seq.

Background: Obesity and metabolic syndrome are major public health concerns linked to cognitive decline with aging. Prior work from our lab has demonstrated that short-term high fat diet (HFD) rapidly impairs memory function via a neuroinflammatory mechanism. However, the degree to which these rapid inflammatory changes are unique to the brain is unknown.

Background: The promotion of healthy dietary behaviors in adolescence is critical, which have long-term implications for lifelong health. Integration is an important method for improving limited theories of dietary behavior change. The present study proposes an integrated model aimed at identifying the diverse determinants of healthy dietary behaviors in adolescents and assesses its stage-specific nature as the potential for effective interventions.

Heart rate variability (HRV) is a key indicator of cardiac autonomic function, making reliable assessment crucial. To examine the test-retest stability of resting HRV in healthy individuals, fifty participants attended two lab sessions within a week, at the same time of day. After a 5-minute acclimatization period, electrocardiogram and respiration were recorded at rest.
