“…This partially supports the findings of Siegler et al [7] reporting patients diagnosed with a memory disorder to score significantly higher on neuroticism and lower on openness, extraversion and conscientiousness. However, our data is not in line with the results of Clement et al [14], who claim that, although psychological distress is present in MCI subjects, they do not differ in personality traits compared to healthy controls. However, it has to be noted that their study had a cross-sectional design and a relatively small sample size.…”

“…Moreover, a higher level of chronic psychological distress is associated with a higher incidence of MCI [12], although Jelicic et al [13] did not identify any relationship between neuroticism and cognitive performance/decline in a sample of healthy older adults. Accordingly, Clement et al [14] reported no differences between MCI subjects and healthy controls with respect to personality traits. These discrepancies may be a result of methodological differences and limitations.…”

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.

Aims: To describe personality traits and their changes in mild cognitive impairment (MCI) and control subjects. Methods: Sixty-three MCI and 90 control subjects were asked to describe their current personality traits by the Structured Interview for the Five-Factor Model (SIFFM). For each subject, a close relative retrospectively assessed these descriptions both as to the previous and current personality traits, using the Revised NEO Personality Inventory, Form R (NEO-PI-R). Results: Self-assessed MCI subjects reported significantly lower scores in the openness dimension than control subjects [F(1, 150) = 9.84, p = 0.002, η_p² = 0.06]. In current observer ratings, MCI subjects had higher scores on neuroticism [F(1, 137) = 7.55, p = 0.007, η_p² = 0.05] and lower ones on extraversion [F(1, 137) = 6.40, p = 0.013, η_p² = 0.04], openness [F(1, 137) = 9.93, p = 0.002, η_p² = 0.07], agreeableness [F(1, 137) = 10.18, p = 0.002, η_p² = 0.07] and conscientiousness [F(1, 137) = 25.96, p < 0.001, η_p² = 0.16]. Previous personality traits discriminated the groups as previous openness [odds ratio (OR) = 0.97, 95% confidence interval (CI) = 0.95-0.99, p = 0.014] and conscientiousness (OR = 0.96, 95% CI 0.94-0.98, p = 0.001) were negatively related to MCI group membership. In MCI subjects, conscientiousness [F(1, 137) = 19.20, p < 0.001, η_p² = 0.12] and extraversion [F(1, 137) = 22.27, p < 0.001, η_p² = 0.14] decreased between previous and current evaluations and neuroticism increased [F(1, 137) = 22.23, p < 0.001, η_p² = 0.14], whereas no significant change was found in control subjects. Conclusions: MCI subjects undergo significant personality changes. Thus, personality assessment may aid the early detection of dementia.

“…In a previous study focusing on the differences in the levels of depressive symptoms between a mild cognitive impairment group and a normal cognitive function group that had been matched based on age and education, the authors found a significantly greater level of depressive symptoms in the mild cognitive impairment group [12]. According to Shin [13], however, the depression level was higher in those with mild cognitive function impairment than in the normal group, but the difference was not statistically significant.…”
