The theory of mind (ToM) is not substantially influenced by aging, suggesting the emergence of various compensatory mechanisms. To identify brain regions subserving ToM in older adults, we investigated the associations of individual differences in brain structure with performance on the Reading the Mind in the Eyes Test (RMET), a widely used measure of ToM, using voxel-based morphometry (VBM) and tract-based spatial statistics (TBSS). In contrast to findings obtained from young adults, where multiple cortical regions are implicated in ToM, VBM analysis revealed a significant positive correlation between RMET score and gray matter (GM) volume only in the right middle temporal gyrus, a region implicated in social cognition.

Purpose: Executive function (EF) has three subsystems: inhibition, updating, and shifting. Of these three, only inhibition is considered to be involved in affective theory of mind (ToM). This study investigated whether inhibition remains the sole driver for affective ToM in the three EF subsystems in older adults as well as in young people without functional reorganization via aging within EF.

This study aimed to verify whether the incidence of frailty in elderly individuals is higher among those who are housebound than those who are not. This study found no correlation between elderly people's houseboundedeness and physical, mental, social, and overall frailty. However, the Tilburg Frailty Indicator (TFI) frailty score and grip strength value were higher in non-housebound elderly persons than in housebound elderly ones.

The rates of care-needs certification were mainly compared between two cohorts: 7,820 specific health checkup examinees/basic checklist respondents and 29,234 non-examinees/non-respondents. Among approximately 37,000 elderly citizens of X City, the number of individuals newly certified as requiring long-term care were observed from the date of the first specific health checkup in 2008 to March 31, 2013. The aggregated totals of these individuals and associated factors were evaluated.

This study aimed to examine the factors influencing the requirement of a certificate of long-term care using a basic checklist and items listed in the Special Health Checkup. This study included 7,820 individuals living in Uji city, who were selected from among 8,000 elderly individuals who, in 2008, underwent a specific health checkup (hereafter referred to as the 'specific health checkup for the old-old elderly individuals') for those aged 75 years and above. They answered questions from basic checklists at the time, and 180 individuals were excluded as they had already qualified for requiring the certificate of long-term care at the time of the checkup.

Background: We examined the relationships between mothers' sense of coherence (SOC) and their child's social skills development among preschool children, and how this relationship is mediated by mother's childrearing style.

Methods: Mothers of 1341 Japanese children, aged 4-5 years, completed a self-report questionnaire on their SOC and childrearing style. The children's teachers evaluated their social skills using the social skills scale (SSS), which comprises three factors: cooperation, self-control, and assertion.
