“…Overall, an enhanced functional connectivity within mesocortical networks may explain why open people display a broad range of interests, an active imagination, and high levels of curiosity and creativity (McCrae and Costa, 1997;McCrae and Sutin, 2009). As mesocortical networks have been involved in adaptive behaviors and survival-oriented responses (Alcaro et al, 2007;Floresco and Magyar, 2006), it may also be that the reduced mortality risk reported in open people has a specific neurobiological basis (Iwasa et al, 2008;Taylor et al, 2009;Turiano et al, 2012).…”

“…Recent findings suggest that more adaptive personality factors such as consciousness, extraversion and openness are inversely related to all-cause mortality. Persons with these characteristics would be more likely to engage in healthy behaviours 35. Feelings of loneliness could then be considered to be an expression of a frailty factor, signifying sensitivity to distress.…”

Feeling lonely rather than being alone is associated with an increased risk of clinical dementia in later life and can be considered a major risk factor that, independently of vascular disease, depression and other confounding factors, deserves clinical attention. Feelings of loneliness may signal a prodromal stage of dementia. A better understanding of the background of feeling lonely may help us to identify vulnerable persons and develop interventions to improve outcome in older persons at risk of dementia.

“…Past studies suggested that neuroticism affects biological or physiological mechanisms and may affect certain clinical outcomes and mortality (Wilson et al 2005;Shipley et al 2007), but recent studies revealed that specified personality traits do not influence mortality (Iwasa et al 2008;Andre et al 2014). According to the hierarchical model of functional and behavioral competence (Lawton and Brody 1969;Lawton 1972), higher-level functional decline consists of the complex abilities required to maintain functional capacity at early stages -IADLs, intellectual activity, and social role performance -which are not diagnosed in certain diseases.…”

Numerous factors that affect functional decline have been identified, and personality traits are considered to be an important factor in functional decline risk. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG) was developed to measure three higher-level functional capacities, instrumental activities of daily living, intellectual activity, and social roles, in Japanese elderly, which were previously not assessed adequately with existing scales of functional decline. The objective of this study was to explore the effect of personality traits as predictors of higher-level functional decline over a 7-year follow-up in a rural Japanese community. Data on 676 participants (mean 67.1 years) who were free of functional decline and had completed questionnaires at baseline and 7 years later, were analyzed. Demographic characteristics, lifestyle and personality characteristics were obtained from a self-administered questionnaire at baseline. Higher-level functional decline was examined using the subscales of the TMIG at baseline and at a 7-year follow-up examination. Over the 7-year study period, 21.7% of eligible participants reported decline in higher-level functional capacity. After adjustment for putative confounding factors, the traits that were significant predictors of decline in higher-level functional capacity at the 7-year follow-up had higher psychoticism scores [odds ratio (95% confidence interval) 2.12 (1.23-3.66)] and lower extraversion scores [1.89 (1.01-3.56)]. The personality traits of higher psychoticism and lower extraversion were significantly associated with a risk of future functional decline. A better understanding of these personality traits may help identify of at-risk individuals and could help reduce functional decline in older adults.
