As the elderly population grows worldwide, living a healthy and full life as an older adult is becoming a topic of great interest. One key factor and severe challenge to maintaining quality of life in older adults is cognitive decline. Assistive robots for helping older adults have been proposed to solve issues such as social isolation and dependent living. Only a few studies have reported the positive effects of dialogue robots on cognitive function but conversation is being discussed as a promising intervention that includes various cognitive tasks. Existing dialogue robot-related studies have reported on placing dialogue robots in elderly homes and allowing them to interact with residents. However, it is difficult to reproduce these experiments since the participants’ characteristics influence experimental conditions, especially at home. Besides, most dialogue systems are not designed to set experimental conditions without on-site support. This study proposes a novel design method that uses a dialogue-based robot system for cognitive training at home. We define challenges and requirements to meet them to realize cognitive function training through daily communication. Those requirements are designed to satisfy detailed conditions such as duration of dialogue, frequency, and starting time without on-site support. Our system displays photos and gives original stories to provide contexts for dialogue that help the robot maintain a conversation for each story. Then the system schedules dialogue sessions along with the participant’s plan. The robot moderates the user to ask a question and then responds to the question by changing its facial expression. This question-answering procedure continued for a specific duration (4 min). To verify our design method’s effectiveness and implementation, we conducted three user studies by recruiting 35 elderly participants. We performed prototype-, laboratory-, and home-based experiments. Through these experiments, we evaluated current datasets, user experience, and feasibility for home use. We report on and discuss the older adults’ attitudes toward the robot and the number of turns during dialogues. We also classify the types of utterances and identify user needs. Herein, we outline the findings of this study, outlining the system’s essential characteristics to experiment toward daily cognitive training and explain further feature requests.

The aim of this study was to examine the association between lifestyle activities, including physical, cognitive, and social activities, and Alzheimer’s disease (AD) signature cortical thickness, as well as to examine the mediating role of AD signature cortical thickness in lifestyle activities and cognitive function in community-dwelling healthy older adults. Participants were 1026 older adults who met the study inclusion criteria. The physical, cognitive, and social activities of daily life were assessed using a self-reporting questionnaire. AD signature cortical thickness was determined using FreeSurfer software. Cognitive function was evaluated using the National Center for Geriatrics and Gerontology-Functional Assessment Tool. Path analysis (based on structural equation modeling (SEM)) of cognitive activities indicated that the direct path from cognitive activities to cognitive function was significant (p < 0.001), as was the direct path from AD signature cortical thickness to cognitive function (p < 0.001). Physical (p < 0.05) or social activities (p < 0.05) had a direct effect on cognitive function. However, AD signature cortical thickness did not mediate the relationship between physical or social activities and cognitive function. Our findings suggest that higher levels of cognitive activities later in life have a significant and positive direct effect on cognitive function. Additionally, AD signature cortical thickness significantly mediates the relationship between cognitive activities and cognitive function.

Abstract Research has found relationships between experiencing stressful events and lower cognitive function in late life. However, there is little research about the cumulative experiences of significant historical events and cognitive function. Historical events may be unique compared to other life events due to their potential distal relationship to the individual. This study aims to examine the relationship between experiencing significant historical events and cognitive function among Chinese older adults. Data were drawn from the PINE Study, a cohort study of 3,126 US Chinese older adults collected from 2017-2019. Participants were asked if they experienced the Japanese invasion, famine, Great Leap Forward, Vietnam War, Cultural Revolution, and the Tian’anmen Square Protests. A composite score of 0-6 was calculated to count the number experienced. Cognitive function was measured through global cognition, episodic memory, working memory, processing speed, and Chinese MMSE. Linear and quantile regression were performed. Among the participants, 1908 (61.04%) were female with mean age of 75.33 (SD=8.22) years. The average number of historical events experienced was 2.36 (SD=1.44). After adjusting for covariates, every one additional historical event experience was associated with better global cognition (b=0.26, SE=0.009, p&lt;.01), episodic memory (b = 0.045, SE=0.012, p&lt;.001), and processing speed (b=0.383, SE=0.135, p&lt;.01). Number of historical events was not significantly associated with working memory or C-MMSE. The positive relationship between historical events and some cognitive domains suggests a potential resilience effect after experiencing historical events. Future research should examine whether participants found events stressful and whether there are differential relationships to cognitive function.

Abstract The increasing diversity in the aging population warrants systematic investigations regarding ethnic differences related to cognitive aging and ethnicity-unique risk factors. However, due to the great paucity of population-based longitudinal data on cognitive aging in racial/ethnic minority populations, our knowledge in this area remain limited. The purpose of this symposium is, therefore, to examine various psychological, socio-cultural, and physical factors associated with cognitive aging among U.S. Chinese older adults, representing one of the biggest and fastest growing older minority populations nationally. Using longitudinal data from a population-based prospective cohort study, namely The Population Study of ChINese Elderly in Chicago (PINE) with a sample size of 3,157, this symposium presents findings from five research projects. Session 1 investigates the relationship between psychological well-being and change of cognitive function over four years. Session 2 and 3 examine the relationships between two socio-cultural factors and cognitive function. Specifically, session 2 investigates the associations between immigration-related factors and the incidence of cognitive impairment. Session 3 explores the relationship between cognitive function and Tai-Chi practice. Session 4 and 5 examine the relationships between two physical health indicators and cognitive aging. Specifically, session 4 examines the relationship between physical function and change of cognitive function over two years. Session 5 explores the association between body mass index and cognitive function decline over two years. Taken together, this symposium aims to further our knowledge of cognitive aging among ethnically/culturally diverse populations. The research findings will identify unique factors related to cognitive aging in older minority populations.

The Relationship

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.

Abstract Background Physical fitness declines with age. Low levels of physical fitness appear to be a risk factor of cognitive impairment. Literature elucidates social networking as a potential moderator for the relationship between physical fitness and cognitive impairment. Present study aimed to examine the relationship between physical fitness and cognitive function among community-dwelling older Malaysians, and if social network moderates said relationship. Methods Data of 2322 representative community-dwelling older adults were obtained from the first wave of the “Longitudinal Study on Neuroprotective Model for Healthy Longevity” national survey. Cognitive function, physical fitness and social network was assessed through Malay-version of Mini-Mental State Examination, 2-min step test and Lubben Social Network Scale-6 respectively. Moderated hierarchical multiple regression was employed to investigate if social networks moderate the relationship between physical fitness and cognitive function. Results A positive association between physical fitness and cognitive function were found upon controlling for covariates. Moderated hierarchical multiple regression revealed social networks to be a moderator of the association between physical fitness and cognitive function. When physical fitness was low, those with small social network revealed lowest cognitive function. Conclusions Social networks moderated the relationship between physical fitness and cognitive function as older adults with low levels of physical fitness and small social networks revealed lowest cognitive function. Therefore, community support or peer-based interventions among physically unfit older adults should be implemented to promote cognitive function.
