“…Our finding that PDS predicted SM difficulties is consistent with a large body of research (Goda et al, 2020; Künzi et al, 2021; Potter et al, 2009; Rönnlund et al, 2011; Sabatini et al, 2021). Since there is a link between chronic stress and PDS conditions, such as depression (Monroe & Harkness, 2005), it has been proposed that long-term PDS may damage the neurogenesis in the hippocampus, a brain region crucial for supporting memory (Dillon & Pizzagalli, 2018).…”

Objectives To investigate how indicators of psychological stress and physical health differentially influence subjective and objective memory in older adults. Methods: 404 adults aged ≥55 without cognitive impairment participated in remote assessment of physical health (PHY; multimorbidity, body-mass-index), psychological distress (PDS; perceived stress, anxiety, depression), subjective memory complaints (SM), and task-based objective memory performance (OM). Results: Separately, both PHY and PDS significantly predicted SM ( p < 0.01), but only PHY was associated with OM ( p = 0.05). Combined models showed that PHY and PDS maintained significant association with SM ( p < 0.01, R2 = 0.30), while only PHY was associated with OM ( p = .07, R2 = 0.03; for associative OM, p = 0.04). Discussion: SM is associated with participants’ psychological profile, highlighting the importance of addressing these factors when assessing SM. The results also reveal that remotely-administered OM tasks are more immune to participants’ psychological profile, and support previously-established links between physical health and objective and subjective memory function.

“…However, the MMSE score was not associated with SCD risk according to our logistic regression analysis. A previous study [ 37 ] has similarly reported that MMSE scores are not associated with the development of SCD in community-dwelling older adults. This is probably because the MMSE score did not fully capture the early stage of cognitive decline observed in SCD.…”

“…SCD morbidity (i.e., KCL-CF score ≥ 1) was found in 35.3% of our study population. This rate has been variously estimated in prior research on community-dwelling older adults at 32.5% [ 28 ], 34.5% [ 36 ], 34.9% [ 29 ], 35.4% [ 37 ], and 37.6% [ 38 ]. Moreover, high response rate to options that suggest SCD was recorded for the following questions: “Do your family or your friends point out your memory loss?” and “Do you find yourself not knowing today’s date?”.…”

Few studies have examined the effects of health literacy on people at risk of developing dementia; its effects on the pathogenesis of subjective cognitive decline (SCD) are particularly unclear. This study aimed to clarify the relationship between health literacy and SCD in a population of healthy community-dwelling older adults. SCD status was assessed using the Cognitive Function domain of the Kihon Checklist (KCL-CF). Health literacy, in turn, was evaluated using the Communicative and Critical Health Literacy (CCHL) scale. Global cognitive function and depressive symptoms were evaluated using the Mini-Mental State Examination (MMSE) and a five-item version of the Geriatric Depression Scale (GDS-5), respectively. Participants who were suspected of having SCD were significantly older than their non-SCD peers, and scored significantly worse on the CCHL, MMSE, and GDS-5. In addition, SCD status was found to be associated with CCHL and GDS-5 scores, as well as age, according to a logistic regression analysis. These findings suggest that low health literacy is linked to SCD morbidity in healthy community-dwelling older adults and should prove useful in the planning of dementia prevention and intervention programs for this population.

“…The MMSE is internationally popular as a screening test for dementia and is characterized by task contents like writing, sentence construction, and graphical imitation. The maximum score is 30 points, and a person is suspected to have dementia if they obtained a score of 23 points or less [ 34 ].…”

Most older adults wish to maintain independence in their familiar communities. However, many experience pain and pain-related disabilities which reduce their health-related quality of life (HRQOL), leading to increased hospitalizations and mortality. This study aimed to determine the impact of physical, mental, and cognitive factors, particularly central sensitization-related symptoms (CSS), on the HRQOL of community-dwelling older adults. A total of 206 participants were included in the analysis, which measured HRQOL, basic attributes, physical functions and body pain, mental factors, cognitive factors, and CSS severity using validated tools. A correlation analysis was used to examine the association between HRQOL and each measure. Furthermore, multiple regression analysis (forced entry method) was performed to identify the factors influencing the HRQOL. The study found that pain intensity and CSS severity significantly influenced the HRQOL among community-dwelling older adults. The higher the pain intensity and CSS severity, the lower their HRQOL. The participants had mild pain and CSS, demonstrating the need to monitor, address, and treat even non-severe issues in community-dwelling older adults. This association, revealed for the first time in this study, suggests that approaches to reduce pain and CSS are important for maintaining and improving the HRQOL of community-dwelling older adults.
