“…It allowed us to investigate the course of personality traits in MCI subjects and healthy controls circumventing potential age confounds. Moreover, the emphasis was on MCI, while many previous studies primarily focused on AD subjects [7,22] or healthy seniors [5,8]. A limitation of the present study is related to the methodology.…”

Background: Personality traits contribute to cognitive functioning. We present a study comparing personality traits in normal ageing and mild cognitive impairment (MCI). Methods: We conducted a representative longitudinal study including 222 subjects from a cohort born between 1930 and 1932 (n = 500) examined at three examination waves (t1: 1993/1994; t2: 1997/1998; t3: 2005/2007). Personality traits were assessed with the NEO-Five-Factor Inventory questionnaire. Results: Healthy controls and patients with MCI showed a significant (p < 0.05) decrease concerning their levels of neuroticism and extraversion over time. MCI subjects scored significantly higher on neuroticism at baseline and lower on openness at all examinations compared to healthy controls. Subjects with higher baseline neuroticism showed a 2.24 times higher risk of developing MCI at the third follow-up (odds ratio = 2.24, 95% confidence interval = 1.12–4.45 – scores adjusted for education and sex). Conclusions: MCI subjects differ in their premorbid personality traits compared to healthy controls. According to our study, higher neuroticism should be considered a risk factor for the development of MCI.

“…Higher extraversion and lower neuroticism scores are associated with higher episodic memory performance in old age [5]. Furthermore, a significant association between verbal memory, general cognitive ability and openness is reported [6].…”

“…Nevertheless, we add interesting information to the growing literature on the ways in which person characteristics such as personality can influence cognitive aspects of aging (in general) and cognitive resilience in late-life (in particular). Recent research indicates that personality influences both cognitive changes (Meier et al, 2002), general compensation (Freund & Baltes, 1998, and memory compensation at one point in time. In this study, one personality trait (i.e., conscientiousness) influenced 6-year change in the use of memory compensation strategies even after controlling for age and education.…”

“…In addition, knowing that episodic memory performance and BDNF levels are both known to decrease steadily with the normal ageing process [45], young adults carrying the Met allele could find themselves at a lower risk of episodic memory alterations due to the abundance of BDNF [46]. Another possible explanation for this age-dependent effect of the BDNF Met variant on episodic memory performance could be that extraversion, a moderating factor of the relationship between genotype and memory performance in the present study, is considerably shaped by experiences over the lifespan, especially by social and stressful experiences, and is negatively associated with age [47,48], in part because of the lower social stimulation found in older adults [35]. In light of these results, it appears likely that among introverted BDNF Met carriers, older adults exhibit, on average, a higher level of introversion than young adults, which could exacerbate between-group differences on memory performance in older adults.…”

“…In older adults (above the age of 60), extraversion has been positively associated with episodic memory, such that extraverted older adults tend to exhibit better free recall abilities relative to age-equivalent introverted individuals [29,34,35]. However, much less research has attempted to study the relation between extraversion and episodic memory performance in young adults.…”

While most studies have been interested in the distinct, predisposing roles of the common BDNF Val66Met variant and extraversion personality traits on episodic memory, very few studies have looked at the synergistic effects of genetic and personality factors to account for cognitive variance. This is surprising considering recent reports challenging the long-held belief that the BDNFMet variant negatively impacts cognitive function. A total of 75 young healthy adults (26 of them carried at least one copy of the BDNFMet allele) took part in this study consisting of genetic profiling from saliva, personality assessment using the Revised NEO Personality Inventory (NEO PI-R) and a short battery of neuropsychological tests. An ANOVA revealed that BDNFMet carriers were significantly less extraverted than BDNFVal carriers (F1,73 = 9.54; p < 0.01; ηp2 = 0.126). Moreover, extraversion was found to significantly moderate the relationship between the BDNF genotype and episodic memory performance (p = 0.03). Subsequent correlational analyses yielded a strong and significant correlation (r = 0.542; p < 0.005) between introversion and delayed episodic memory specific to BDNFMet individuals. The present study suggests that introversion and the BDNFMet variant synergistically interact to reduce episodic memory performance in healthy, young adults. These findings reaffirm that a more accurate explanation of cognitive variance can be achieved by looking at the synergistic effects of genotype and phenotype factors.
